The Missing Ocean on Mars.  Recent measurements indicate that  water once covered ~20% of the planet's surface. 13% of the original water remains in the polar ice caps while 87% has been lost to space. Curiosity found evidence that Mars may had water for 1.5 billion years - plenty of time for something interesting to happen. (It only took about 1 billion for simple-celled life to develop here on Earth.) :)

For decades, planetary scientists have suspected that ancient Mars was a much warmer, wetter environment than it is today, but estimates of just how much water Mars has lost since its formation vary widely. Now, new isotopic measurements by researchers at NASA's Goddard Space Flight Center reveal that an ocean once covered approximately twenty percent of the Martian surface. This new picture of early Mars is considerably wetter than many previous estimates, raising the odds fort... more »

Google is making a wristband which can detect disease

Google is trying to develop a wristband that would be able to detect signs of cancer and other diseases as they appear in your body. All you have to do is swallow a pill that has magnetic nanoparticles with surface markers that will circulate in your bloodstream and bind to cancer cells. A wristband monitor would attract and count the particles, collecting information about what the particles had detected. Wow…talk about diagnostics.

Asteroid Miners May Get Help from Metal-Munching Microbes

Asteroid mining may become a multispecies affair.

The asteroid-mining firm Deep Space Industries (DSI) is investigating the feasibility of injecting bioengineered microbes into space rocks far from Earth, to get a jump on processing their valuable resources.

"You could come back [to the asteroids] in 10 to 20 years and have a preprocessed pile of materials," Joseph Grace, of DSI and NASA’s Ames Research Center, told Space.com last month at the annual fall meeting of the American Geophysical Union (AGU) in San Francisco.

The scientists working on the concept envision launching a small probe that DSI is developing, called Mothership, out to a promising near-Earth asteroid in deep space. Mothership would be carrying a number of tiny CubeSats, one of which would deploy and spiral downt... more »

Zombies, Run!  View while trying out the zombie-gamified running app today.  Fun!  https://zombiesrungame.com/.  :)

How it works: Walk, jog, or run (with your smart phone) - listen to music while the story unfolds in real-time. You get missions to help out  and (hopefully) survive the zombie apocalypse. When the zombies come, run! 

Probably can't tell from the picture, but there's about five progressively more distant horizons - the view goes on forever. :)

When sanctuaries are burning and peaceful worshippers are murdered, it really is persecution.   

http://dictionary.reference.com/browse/persecution

#WhoIsBurningBlackChurches 

This story is finally starting to hit the major press: in the past week, six black churches have burned down. Three of them are being investigated as arson, and the other three are still being examined by fire investigators -- but are highly likely to be arson as well.

I try to put this into my own world and imagine: if six synagogues had been torched the week after a major anti-Semitic terrorist attack, I would be thinking about nothing else. It would be front page, above the fold, in every newspaper in the country. Why, then, is this only now receiving proper coverage?

If you ask why these churches are so important -- why these aren't just ordinary arsons, or arsons against churches first and black churches second -- you can go back to what President Obama said in his eulogy for Clementa Pinckney a few days ago (which people are starting to refer to as "the 'grace' speech"):

The church is and always has been the center of African American life; a place to call our own in a too-often hostile world, a sanctuary from so many hardships.

Over the course of centuries, black churches served as hush harbors, where slaves could worship in safety, praise houses, where their free descendants could gather and shout “Hallelujah.” Rest stops for the weary along the Underground Railroad, bunkers for the foot soldiers of the civil-rights movement.

They have been and continue to community centers, where we organize for jobs and justice, places of scholarship and network, places where children are loved and fed and kept out of harms way and told that they are beautiful and smart and taught that they matter.

That’s what happens in church. That’s what the black church means — our beating heart, the place where our dignity as a people is inviolate.

"The place where our dignity as a people is inviolate:" one of the best distillations of an idea I have heard. A phrase likely to enter the English lexicon. These churches are not simply houses of worship to a god you or I may not share; they are the centers of their communities, and more, they are and have been the refuges and safe harbors of their communities since the days of slavery.

I am glad to see that the news is finally covering this, but why has it taken so long? And how long will it take to stop those responsible, and bring the ones who have already burned buildings to justice?

For the most part, the world has moved beyond the most horrific and public punishments intended to produce suffering.  In general, the state no longer punishes for revenge, but acts to uphold fairness and justice. Those who fail to follow the rules of civilized society are issued an adult "time-out" and lose the privilege of participating.

It's time to reject out-dated, barbaric, deadly punishments. They've never been fair[9], they cost additional time and money, and they demean those of us who desire, order, and implement them. They have no place in advanced societies.

Everything is connected. :)

On care for our common home

Pope Francis has written something about environmental issues.  I recommend it!   Here are two quotes:

If we approach nature and the environment without this openness to awe and wonder, if we no longer speak the language of fraternity and beauty in our relationship with the world, our attitude will be that of masters, consumers, ruthless exploiters, unable to set limits on their immediate needs. By contrast, if we feel intimately united with all that exists, then sobriety and care will well up spontaneously.

Everything is connected. Concern for the environment thus needs to be joined to a sincere love for our fellow human beings and an unwavering commitment to resolving the problems of society. Moreover, when our hearts are authentically open to universal communion, this sense of fraternity excludes nothing and no one. It follows that our indifference or cruelty towards fellow creatures of this world sooner or later affects the treatment we mete out to other human beings. We have only one heart, and the same wretchedness which leads us to mistreat an animal will not be long in showing itself in our relationships with other people.

For more, try my blog post.

How Tesla will change the world. Interesting article about a very important topic.

#energy #outlook #economy #environment #transport #sustainability #abundance

I occasionally will write a long article. This article is, I have to say, longer than even what I would write. But it explains a tremendous number of really important things extremely clearly: power production and use, the history of cars, how these things all fit together, and how Tesla is trying to change that. There's no way I could give you a useful short summary, because the point of this article is that, by the time you're done reading it, you'll understand all of the things well enough that you can join in very serious conversations about them.

So don't feel compelled to read this at one sitting -- but this is an article you may want to bookmark, and read bit by bit, because by the time you reach the end, you'll have learned a lot.___How Tesla will change the world. Interesting article about a very important topic.

Choosing between options is hard. There are so many possible opportunities and adventures; the idea that we can only take one path through the infinite possibilities of life never seems enough - yet each day overflows with wonder and beautiful, amazing things if we put our attention right.

"That sounds like a really good idea, but it would be an even better idea for someone who didn't already have a good job."

That logic made some sense to me, and he convinced me to think about it for 48 hours before making a final decision. Seen in that light, it really was a difficult choice, but ultimately, I decided I had to give it a shot. I didn't think I'd regret trying and failing. And I suspected I would always be haunted by a decision to not try at all. After much consideration, I took the less safe path to follow my passion, and I'm proud of that choice.

The founder of Amazon goes on to share some very good questions. They help remind me to make the most of the little time I get.

Tomorrow, in a very real sense, your life -- the life you author from scratch on your own -- begins.

How will you use your gifts? What choices will you make?

Will inertia be your guide, or will you follow your passions?

Will you follow dogma, or will you be original?

Will you choose a life of ease, or a life of service and adventure?

Will you wilt under criticism, or will you follow your convictions?

Will you bluff it out when you're wrong, or will you apologize?

Will you guard your heart against rejection, or will you act when you fall in love?

Will you play it safe, or will you be a little bit swashbuckling?

When it's tough, will you give up, or will you be relentless?

Will you be a cynic, or will you be a builder?

Will you be clever at the expense of others, or will you be kind?

In the end, we are our choices. Build yourself a great story. 

Commencement is a bit bigger event, but really we awaken every day and into each moment. What we do today matters. Steve Jobs at his commencement address in 2005 said:

When I was 17, I read a quote that went something like: "If you live each day as if it was your last, someday you'll most certainly be right." It made an impression on me, and since then, for the past 33 years, I have looked in the mirror every morning and asked myself: "If today were the last day of my life, would I want to do what I am about to do today?" And whenever the answer has been "No" for too many days in a row, I know I need to change something.

Remembering that I'll be dead soon is the most important tool I've ever encountered to help me make the big choices in life. Because almost everything — all external expectations, all pride, all fear of embarrassment or failure — these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.

Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma — which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.

Europa mission may include a lander. The Europa Clipper mission planned for launch in 2022 (arrival in 2025 via SLS) may get approval for a soft lander - and a chance to discover life.

A soft lander could sample the surface, do mass spectroscopy, and carry instruments such as a microscope and imaging camera. It would have the best chance of assessing whether life might exist in the oceans beneath the ice.

The Dehumanising Insanity of Prohibition

This is one of the best pieces I've read, certainly in recent times, about the war on drugs, drug decriminalisation, drug legalisation, drug addiction, prohibition, and psychology. It's a longish piece at about 10k words based on an interview with famed (infamed?) journalist Johann Hari regarding his recent book Chasing the Scream: The First and Last Days of the War on Drugs. but well worth anyone's time.

Key quotes:

Power concedes nothing without a struggle.

It’s not your morality and it’s not your brain. To a much larger degree than we’ve ever before appreciated, it’s your cage. Addiction is an adaption to your environment.

Anywhere in the developed world, people near you are being giving loads of heroin in hospitals [right] now.

In the culture of terror created by prohibition, if you are prepared to push the moral limit a little bit further than the other guys, you gain a brief market advantage, because people will back off when they’re scared.

But ever since Prohibition we’ve known that the cure is worse than the disease. When you ban substances that people enjoy using so much that they’ll break the law to do it, you create a black market with huge profits. And since purveyors of illicit drugs have no legal way to secure their investment, the trade will be run by increasingly violent criminals. In a single stroke, therefore, prohibition creates organized crime and all the social ills attributable to the skyrocketing cost of drugs—addicts are forced to become thieves and prostitutes in order to afford their next fix.

What we do at the moment is take people who are addicted because they are isolated, distressed, and in pain, and inflict more isolation, distress, and pain on them in the hopes that it will make them stop.

You and I have probably got enough money in the bank that we could spend the next year drinking vodka and never stop. We could just be drunk all the time. But we don’t. And the reason we don’t is not because someone’s stopping us but because we want to be present in our lives. We’ve got relationships. We’ve got friends. We’ve got people we love. We’ve got books we want to read. We’ve got books we want to write. We’ve got things we want to do. Most of addiction is about not wanting to be present in your life.

We can understand why the Portuguese system works so well, because it’s all about reconnecting people with the collective, with the group, with the society, giving them a purpose.

The A options are truly egregious - very wrong and constitutionally protected (thank goodness!) in the United States - we cannot make religious requirements or prohibitions legal. The B options are not violations - they are necessary conditions to ensure that no religious liberty violations take place. 

It's like the way we used to teach sharing with kids - one decides how to cut the cookie (make the rule), and the other gets to pick their side (favored or not).  A fair approach works well for all parties.  :)

Improving boiler efficiency with new biotemplates and wicking technologies - could be 3x more efficient w/2x the steam. Fascinating article from +Rajini Rao on recent work at Drexel University.

How to Boil Water

❉ In breaking news, scientists have figured out how to boil water - at least 3 times more efficiently and producing twice as much steam. Before you shake your fist at "wasteful research spending", this isn't really about your whistling tea kettle! 

❉ Phase change heat transfer processes (boiling, condensation) are a big part of everyday technology from water purification and HVAC units, power plants and cooling electronics.   When water boils, a thin layer of steam can coat the heated surface, insulating it and drastically cutting down on the efficient transfer of heat to liquid. This can lead to surface burnout and a destructive condition known as critical heat flux. What is needed is a surface that discourages the vapor from sticking and wicks in water to quickly re-wet the heated surface. To create a superhydrophilic wicking surface, Drexel University scientist Matthew McCarthy turned to biotemplating with....viruses! 

❉ The tobacco mosaic virus causes mottling of tobacco leaves, as its name implies, but is harmless to humans. It was the first virus ever to be discovered (in the late 1880's) and is constructed simply of repeating units of a coat protein, wrapped around a single, helical strand of genetic material (RNA). A few tobacco plants can produce billions of virus particles, so it's cheap to make. Dr. McCarthy tweaked the coat protein so it sticks to any engineered surface- from silicon to steel. After dunking the surface in a viral broth, nickel and palladium are added to grow a metallic grass

❉ The viral tendrils work like a wicking surface, drawing down water to replace what's boiled away.  It's the same idea behind thermal fabrics designed for athletes which draws moisture away from the body. They say a watched pot never boils. I'd volunteer to test a virally coated tea kettle, how about you? 

Waterproofin' with Hydrophobin: This old post shows how a fungal spore protein can do the opposite, creating a superhydrophobic surface that repels water but allows gases to exchange.

Happy to hear that Saudi Arabia has restored their ambassador to Sweden.  It's good that the conversations between these important nations continue.

I'm impressed with Saudi Arabia's decision, and with the diplomacy, courage, and assessment provided by Swedish foreign minister, Margot Wallström.  The conversation deserves support.  

Thanks +Jochen Fromm and +Russ Abbott for sharing.

#humanrights   #saudiarabia   #sweden   #international   #collaboration   #diplomacy  

A few weeks ago Margot Wallström, the Swedish foreign minister, denounced the subjugation of women in Saudi Arabia. As the theocratic kingdom prevents women from travelling, conducting official business or marrying without the permission of male guardians, and as girls can be forced into child marriages where they are effectively raped by old men, she was telling no more than the truth. Wallström went on to condemn the Saudi courts for ordering that Raif Badawi receive ten years in prison and 1,000 lashes for setting up a website that championed secularism and free speech. These were ‘mediaeval methods’, she said, and a ‘cruel attempt to silence modern forms of expression’. And once again, who can argue with that?

The backlash followed the pattern set by Rushdie, the Danish cartoons and Hebdo. Saudi Arabia withdrew its ambassador and stopped issuing visas to Swedish businessmen. The United Arab Emirates joined it. The Organisation of Islamic Co-operation, which represents 56 Muslim-majority states, accused Sweden of failing to respect the world’s ‘rich and varied ethical standards’ — standards so rich and varied, apparently, they include the flogging of bloggers and encouragement of paedophiles. Meanwhile, the Gulf Co-operation Council condemned her ‘unaccept-able interference in the internal affairs of the Kingdom of Saudi Arabia’, and I wouldn’t bet against anti-Swedish riots following soon.

Yet there is no ‘Wallström affair’. Outside Sweden, the western media has barely covered the story, and Sweden’s EU allies have shown no inclination whatsoever to support her. A small Scandinavian nation faces sanctions, accusations of Islamophobia and maybe worse to come, and everyone stays silent. As so often, the scandal is that there isn’t a scandal. [Emphasis added]

World Factbook
on +Android 

Redditor gray_dorian has put the CIA World Factbook onto Android.  Thanks to open government the CIA does not provide an API for the World Factbook (so that the data could be read programmatically) so the data had to be scraped via a zip file, then more recent data added from CSV files. A custom parser was created, the data cleaned and then the rationalised data was loaded into an SQLite database.

NO PERMISSIONS, NO TRACKERS, NO ADS. CIA World Factbook app does not spy on you!

This a FREE app to browse World Factbook, a guide prepared by the Central Intelligence Agency for use by US Government officials.

Now, there are already a few similar apps on Play Store, what makes this app unique is:
- Designed for phones and tablets
- Speed, the app is super fast
- Only one click to see the country details
- Countries sorted by GDP by default, no longer Afghanistan is at the top place
- Tabbed interface to quickly switch between continents and categories
- Drawer menu to sort countries by any measurable indicator (GDP, Area, Population etc)
- Compare North vs South Korea or any other two countries side-by-side
- Browse through country flags in grid-mode
- See Guide for fields

Note: this application is not associated with the CIA

Are you looking for solutions, or comfort?

There may not be a more important question to ask someone who's not feeling his or her best. Offering solutions, my natural response, can come across as overbearing or manipulative when comfort is wanted. Conversely, comfort can seem distant or shallow to someone looking for solutions. ___This is beautiful.  Not just because the question is so helpful, but because "adventure for solutions" is such a perfect way to describe the request. :)

In many areas we take water for granted. However, in some parts of the world, it takes enormous effort to get water. Stella Artois and water.org are working together so that 1 limited edition chalice equals 5 years worth of clean drinking water.

The Missing Ocean on Mars.  Recent measurements indicate that  water once covered ~20% of the planet's surface. 13% of the original water remains in the polar ice caps while 87% has been lost to space. Curiosity found evidence that Mars may had water for 1.5 billion years - plenty of time for something interesting to happen. (It only took about 1 billion for simple-celled life to develop here on Earth.) :)

For decades, planetary scientists have suspected that ancient Mars was a much warmer, wetter environment than it is today, but estimates of just how much water Mars has lost since its formation vary widely.

Skunk Works claims continued progress on compact fusion.

Lockheed Martin's Skunk Works claims the ability to generate cheap energy from nuclear fusion with little waste or global warming is within its grasp.

This is the same Skunk Works created by the near-mythical Kelly Johnson, an aerospace engineer able to head teams that built the SR-71 Blackbird reconnaissance jet years before any other organization even thought Mach-3 flight was possible.

The Lockheed Martin project is designed to take advantage of the practice of rapid prototyping that the Skunk Works pioneered by building relatively small, easily improved incremental projects that lead to a finished product that actually works.

Currently Lockheed Martin is in the process of testing a magnetic confinement bottle, where the Skunk Works team has apparently made significant progress. In terms of how a fusion reactor would be created, the magnetic bottle is the primary hurdle.
 
If that's accomplished successfully most of the science and engineering is known. However, that doesn't mean that building the prototype fusion reactor is a done deal. Lockheed Martin is looking for industry partners to help develop the Compact Fusion reactor into a real product.

What is gravity, really? Physicist +Brian Koberlein writes an interesting and accessible article on our understanding of gravity. 

"...we found gravity wasn’t a force at all...[it's] a warping of spacetime. Basically, mass tells space how to bend, and space tells mass how to move."

[emphasis mine]

#physics  #gravity #spacetime

Cradle to Grave

Gravity is perhaps the best known of the four fundamental forces. It’s also the one that’s easiest to understand. At a basic level, gravity is simply the mutual attraction between any two masses. It’s the force that lets the Sun hold the planets in their orbits, and the force that holds the Earth to you. The force is always attractive, and the strength of the force between two masses depends inversely on the square of their distances, making it an inverse square force. But gravity’s simplicity is just a veneer that hides a deeply subtle and complex phenomenon.

When Newton proposed his model of universal gravity, one criticism of the model was how gravity could act at a distance. How does the Moon “detect” the presence of Earth and “know” to be pulled in Earth’s direction? A few ideas were proposed, but never really panned out. Since Newton’s model was so incredibly accurate, the action-at-a-distance problem was largely swept under the rug. Regardless of how masses detected each other, Newton’s model let us calculate their motion. Another difficulty came to be known as the 3-body problem. Calculating the gravitational motion of any two masses was straight forward, but the motion of three or more masses was impossible to calculate exactly. The motion could be approximated to great precision, and was even used to discover Neptune, but an exact, general solution for three masses would never be found. Newton’s idea was simple, but it’s application was complex.

In the early 1900s, we found that gravity wasn’t a force at all. In Einstein’s model, gravity isn’t a force, but rather a warping of spacetime. Basically, mass tells space how to bend, and space tells mass how to move. General relativity isn’t just a mathematical trick to calculate the correct forces between objects, it makes unique predictions about the behavior of light and matter, which are different from the predictions of gravity as a force. Space really is curved, and as a result objects are deflected from a straight path in a way that looks like a force.

But despite its simple approximation as a force, and its beautifully subtle description as a property of spacetime, we’ve come to realize over the past century that we still don’t know what gravity actually is. That’s because both Newton’s and Einstein’s models of gravity are classical in nature. We now know that objects have quantum properties, with particle-like and wave-like behaviors.  When we try to apply quantum theory to gravity, things become complicated and confusing. In most quantum theory, quantum objects exist within a background framework of space and time. Since gravity is a property of spacetime itself, fully quantizing gravity would require a quantization of space and time. There are several models that attempt this, but none of them have yet achieved a fully quantum model.

Usually our current understanding of gravity is just fine. We can accurately describe the motions of stars and planets. Seemingly odd predictions such as black holes and the big bang have been confirmed by observation. Every experimental and observational test of general relativity has validated its accuracy. Large objects with strong gravity can be described just fine by classical gravity. For small objects with weak gravity we our approximate quantum gravity is good enough. The problem comes when we want to describe small objects with strong gravity, such as the earliest moments of the big bang.

Without a complete theory of quantum gravity, we won’t fully understand the earliest moment of the universe. We know from observation that the early observable universe was both very small and very dense. From general relativity this would imply that the universe began as a singularity. Most cosmologists don’t think the universe actually began as a singularity, but without quantum gravity we aren’t exactly sure. Even if we put the quantum aspects of gravity aside, there is still a part of gravity we don’t understand. Within general relativity it is possible to have a cosmological constant. Adding this constant to Einstein’s equations causes the universe to expand through dark energy, just as we observe. While general relativity allows for a cosmological constant, it doesn’t require one. The cosmological constant agrees with what we observe, but there are other proposed models for dark energy that agree as well (at least for now). If dark energy is really due to the cosmological constant, then the constant must be very close to zero, at about 10-122. Why would a constant be so incredibly close to zero? Why does it even exist when general relativity doesn’t require it?

We don’t know, and without that understanding, both the origin and fate of the universe remain mysteries.

Tomorrow: Electromagnetism was the first unified theory, combining the forces of magnets and charges. The result gave us a new understanding of light, and led us down a path toward a theory of everything.___What is gravity, really?

Asteroid Miners May Get Help from Metal-Munching Microbes

Asteroid mining may become a multispecies affair.

The asteroid-mining firm Deep Space Industries (DSI) is investigating the feasibility of injecting bioengineered microbes into space rocks far from Earth, to get a jump on processing their valuable resources.

"You could come back [to the asteroids] in 10 to 20 years and have a preprocessed pile of materials," Joseph Grace, of DSI and NASA’s Ames Research Center, told Space.com last month at the annual fall meeting of the American Geophysical Union (AGU) in San Francisco.

The scientists working on the concept envision launching a small probe that DSI is developing, called Mothership, out to a promising near-Earth asteroid in deep space. Mothership would be carrying a number of tiny CubeSats, one of which would deploy and spiral down to the asteroid’s surface.

The CubeSat would then inject into the asteroid a low-temperature fluid laden with bacteria, which would propagate through cracks and fissures generated by the injection process. Over time, the microbes — genetically engineered to process metals efficiently — would break down harmful compounds within the asteroid and/or transform resources into different chemical states that are more amenable to extraction.

This work would be slow, but the bacteria would be doing it for free (after the initial expenditure of getting them out to the asteroid, of course).

"The use of self-sustaining biomining mitigates the need for sustained docking, anchoring, drilling, processing or other technically challenging traditional mining approaches," Grace and his colleagues wrote in a poster they presented at AGU. "If shown to function, the use of life to preprocess valuable deep-space resources could change the economic practicality of a large range of human activity in space."

All you have to do is swallow a pill that has magnetic nanoparticles with surface markers that will circulate in your bloodstream and bind to cancer cells. A wristband monitor would attract and count the particles, collecting information about what the particles had detected. Wow…talk about diagnostics.

Energy industry changes could happen faster than expected. “Should solar continue on its exponential trajectory, the energy infrastructure will be 100-percent solar by 2030,” [Tony] Seba said. “The only reason for this not to happen is that governments will protect or subsidize conventional coal, nuclear, oil, gas generating stations—even when this means higher prices for consumers.”

Although the exact time may be debated, the idea that the cross-over point may come sooner than expected is interesting.

As a rule, Seba said, when a technology product achieves critical mass (historically defined as about 15-20 percent of the market), its market growth accelerates further, and sometimes exponentially, due to the positive feedback effects. In hundreds of markets around the world, unsubsidized solar is already cheaper than subsidized fossil fuels and nuclear power. A new Deutsche Bank report just made headlines at the end of October for predicting that solar electricity in the US is on track to be as cheap or cheaper than fossil fuels as early as 2016.

Within just 15 years, he said, solar and wind power will provide 100 percent of energy in competitive markets, with no need for government subsidies.

TRIGGER WARNINGS FOR RAPE DISCUSSION

Campus Rape: It's Not All Misogyny

Amongst those who frequently talk about rape and other sexual assault issues pertaining to male perpetrators and female victims, there is often an assumption that rapists are aggressively hostile towards women.  But open hostility - such as believing that women are all asking for it, that they're sluts who manipulate men into buying gifts and dinners and then don't put out, or other typically stated resentments by so-called "men's rights activists" (MRAs) and "pick up artists" (PUAs) - is not actually required for rape to occur.

The key difference lies in whether the man himself thinks of what he's doing as rape or not.  Several studies and reports have circulated in recent years indicating that a lot more men will admit to descriptive situations that involve coerced sex as long as you don't use the word rape in the description.  We've several chilling stories about how men will casually admit to having had sex with a woman who was unconscious, having used roofies, or having used some of the PUA techniques that involve physical coercion because they feel entitled to sex in these situations and fundamentally do not see themselves as having raped anybody.

Even victims don't often want to admit they've been raped.  That word is so loaded with ugliness, trauma, and victim-blaming that many victims themselves will go to lengths to explain away a rape, especially during the initial trauma period.  This is part of why we've seen calls for rape investigations to be less brutal towards victims, less requiring of nailed-down specifics, and more flexible as their minds process what happened over time.  Unfortunately, because our society is still so deeply mired in victim-blaming, many of these attempts to revise justice systems or reporting systems get written off as allowing female victims time to "make things up" instead of recognizing the psychological processes at work.

A new study by Sara Edwards, PhD, and Kathryn Bradshaw of University of North Dakota in Grand Forks, and Verlin Hinsz, PhD of North Dakota State University in Fargo, appearing in the peer-reviewed journal Violence and Gender entitled “Denying Rape but Endorsing Forceful Intercourse: Exploring Differences Among Responders,” (available for free at http://online.liebertpub.com/doi/full/10.1089/vio.2014.0022 until February 6, 2015) contrasted male survey respondents who were willing to engage in coercive sexual activities versus those who were willing to rape in terms of their responses to other survey elements geared to gauge their relative hostility towards women versus a callous sexual attitude as part of wider hyermasculinity.

Hostility towards women was measured using statements as I've mentioned above, and the callous sexual attitude measurement looked at what many of us engaged in activism typically refer to as entitlement: the objectification of women, the supposition that "real men" are sexually dominant and "score" a lot, that men allegedly have uncontrollable desires, and that therefore if a man is to be a "real man" he needs to be supplied with sex regardless of whether the woman involved really wants to or not.

From the study:

Given that callous sexual attitudes permit violence and consider women as passive sexual objects, it follows that for men who endorse these, sexual aggression becomes an appropriate and accepted expression of masculinity. In this sense, using force to obtain intercourse does not become an act of rape, but rather an expression of hypermasculinity, which may be thought of as a desirable disposition in certain subcultures. Taken together, these research findings suggest that an expression of hypermasculinity through callous sexual attitudes may relate to an inclination to endorse a behavioral description (i.e., using force to hold an individual down) versus referring to a sexually aggressive act as rape. Hence, we hypothesize that the construct of callous sexual attitudes will be found at the highest levels in those men who endorse intentions to force a woman to sexual acts but deny intentions to rape.

In other words, the researchers wanted to see if this entitlement attitude many of us have been decrying is linked to approval for coerced sex if you take away the loaded word "rape", versus requiring actual hostile misogyny to approve of such situations.

And it is.

Their conclusion:

As hypothesized, a sizable number of participants indicated that they might use force to obtain intercourse, but would not rape a woman. Men who indicate intentions to use force but deny intentions to rape exhibit a unique disposition featuring an inverse construct of hostility toward women but high levels of callous sexual attitudes (Check 1985). Given that hostility toward women involves resentment, bitterness, rejection sensitivity, and paranoia about women's motives, we consider the inverse of hostility toward women in men that intend to use force to be indicative of an affable, trusting, and nonreactive affect toward women. When combined with callous sexual attitudes, we interpret this function as representing personality characteristics that might lend themselves to allowing men to not perceive his actions as rape and may even view the forced intercourse as an achievement. The primary motivation in this case could be sexual gratification, accomplishment, and/or perceived compliance with stereotypical masculine gender norms. The use of force in these cases might be seen as an acceptable mean to reach one's goal, or the woman's “no” is perceived as a token resistance consistent with stereotypical gender norms. While the ultimate outcome of either act constitutes rape, this pattern of results suggests that there might be different types of offenders with potential differences in underlying motivation, cognition, and/or personality traits.

I want to highlight some phrases in there:

"an affable, trusting, and nonreactive affect toward women" - This is why so many victims of rape are so mind-boggled by the event that they themselves don't know how to label it, because he was their friend.  He was that nice guy, that harmless guy, that funny guy, that decent fella everyone likes.  So even if the victim can get over her own mental roadblock and realizes, "He is not nice because HE RAPED ME," when she reports this to mutual friends, she is routinely met with disbelief.  "What? Him?  No way!  He's so nice!  He'd never do that!"  Except that he did, and now the victim is plunged into a world of self-doubt, doubt by friends, and questions from all sides about what she did to make this happen.  Did she lead him on?  Did she ever flirt with him or send him mixed signals?  Those questions should be irrelevant but that's what she'll get in her face constantly, even from within her own head.

"may even view the forced intercourse as an achievement" - This is why so many of us complain about casual use of women as prizes in literature/movies/games/other entertainment, even down to those items geared towards very young children.  When we routinely enforce the girl-as-prize trope, we are helping to enforce a key component of a set of attitudes that is leading to real-life rape.  The stories and games that deliver women as literal prizes to "heroes" rarely give the woman a choice in this outcome, teaching girls and boys, men and women that female consent is irrelevant if the male has "earned" this reward, or worse, that a female who withholds consent at the point of being a prize is breaking the game or wrecking the ending.

"The primary motivation in this case could be sexual gratification, accomplishment, and/or perceived compliance with stereotypical masculine gender norms." - Or what many of us simply call "entitlement", the notion that a man is allowed to have these things, that women are provided by fate or circumstances to supply it, and if women don't like it they shouldn't go out, shouldn't wear that dress, shouldn't drink, or shouldn't live their lives.  Because boys will be boys and apparently part of that is being allowed to stick your penis in any available vagina, with "availability" not necessarily including "clear consent".

"the woman's “no” is perceived as a token resistance consistent with stereotypical gender norms" - This is why we chant, "Whatever we wear, wherever we go, yes means yes and no means no!"  Because PUA training (and society in general) tells men that women really do want to say yes to them but have to be coerced into it one way or another so women can free themselves from the sexist bonds of the supposed morality of chastity.  Some PUAs even see themselves as heros of sexual liberation, casting themselves in such a positive light that they cannot comprehend why they ever get negative reactions.

Plus it implies that a woman who has said yes before - to that man or to any other man - then somehow owes more yeses, because that chastity gate has been unlocked and therefore is expected to remain unlocked for all time.

All of this concocted nuance about the word "no" misses the point that "no" should be seen as an absolute.  If a man suspects a woman of playing "head games" and meaning "yes" when she says "no", he should either directly ask for clarification or go with the assumption of "no" meaning "no" until the woman herself changes it to a "yes" of her own volition.  Because here's a hint to the male "players" out there: most of the time when a woman says "no" to you she does not want to have sex with you and you need to get over your entitlement issues and move along.


So what does all of this mean for campus rape prevention?  It means we can't keep just screaming, "Misogyny!" at the obvious MRAs and PUAs and expect anything to get better, because to be blunt, the actual misogynists are not going to listen anyway.  But this study reveals inroads to getting to those men who are raping while defining it away in their own minds as something else, the ones who seem "like such a nice guy" but apparently don't mind scoring points with their brethren using coercive techniques upon women.

The authors conclude,

Men who are primarily motivated by negative, hostile affect toward women and who conceptualize their own intentions and behaviors as rape are unlikely to benefit from the large group primary prevention efforts done as part of college outreach efforts. However, programming using a group and norm-based approach appears to be appropriate for men who endorse force but deny rape, as long as the programming can establish rapport and credibility with participants. Because these men do not view their sexually aggressive intentions as rape, failing to attend to issues around beliefs about the stereotypical rapist and not identifying with them could weaken the effectiveness of the programming due to not receiving buy in from participants. This would ultimately likely leave the men who could benefit most from these prevention efforts disengaged.

In other words, we need to establish campus-specific socialization programs that reduce the need for and spread of hypermasculine norms, which frankly would benefit many men anyway since many men do not want to engage in those narrow definitions of what constitutes a "real man".  The traditional campus hazing rituals and party games that emphasize "real manhood" in terms of aggression, drunkenness, and other stereotypical "masculine" behaviours need to be barred from campuses entirely.  Further, there needs to be real education available in a non-obtrusive way that suggests alternative definitions of masculinity that embrace all men - gay, straight, nerds, jocks, etc - while simultaneously clamping down on any lingering "boys will be boys" excuses that not only allow perpetual violence but help to enforce it as a valid behaviour in the first place.

This might mean that some of the blunt campaigns those of us who already get it favour - like posters that simply say, "Don't Rape" - are not effective with the "callous sexual attitude" set because as far as they're concerned, they're not raping so they'll ignore those posters.  Better simple slogans may be those that emphasize consent - ie "No means no" and "Absence of No Does Not Mean Yes" - may be more effective.  We need other strategies to get and hold the attention of men who already have a callous sexual attitude and turn them away from that, using their own social groups to bolster these strategies because that's going to be a lot more effective than an external force coming forth with what seems like a scolding for something they're pretty sure they've never done.

We also need to do better at seeding the concepts of female autonomy and required consent on a wider social scale.  That means shunning those games/movies/books/etc that promote women as prizes or sex as a point system.  Male virgins need to no longer be objects of ridicule while female virgins need to no longer be objects of high value.  "Deflowering" and "cherry popping" need to go in terms of concepts of some kind of special event men get to apply to women.  First sex is over-romanticized all over the place which is bad enough for so many reasons outside the scope of this article, but specifically making it a prize that experienced men get to win out of inexperienced women needs to be seen as creepy, not points to be won.

Lastly, as I have said so many times, a lot of this has to come from the men who get it towards the men who don't.  That can be as simple as no longer silently standing by when your male friends display callous sexual attitudes.  Stand up and say, "Hey, that's not cool" when you hear rape jokes in your video game sessions.  When your friend in the bar is assigning point values to women around the room, try saying, "Or maybe they're human beings and not prizes for you to win."  For too long the actual good guys have lived in fear of rejection by the jerks.  It's time to turn that around and speak out so the jerks are the ones being ostracized for their ugly attitudes, and that can only happen if those of you who know better take the initiative and do it.

Banhammer is in effect for any comments that engage in victim-blaming or derailment from the focus of this study.

PS If you think you may have coerced someone into sex or think you might be inclined to do so, don't bury that.  Deal with it.  Start by seeking professional counselling because that professional can help you figure out what you're doing wrong, how to stop it, and what, if anything, you need to do to rectify what you've already done.___Gender and Violence.   Socially acceptable violence: rape is unacceptable to 86.4%, yet a sizable number of participants  (31%) indicated that they might use force to obtain intercourse.

TW: Rape: Rape culture and Sexual Coercion
Here is an outstanding post by +Kimberly Chapman who discusses research on how men misunderstand the concept of rape. As I wrote on Kimberley's original thread, there is a lot of social science research showing that the socialisation of sex is a big part of this problem. Men and women don't know how to recognise rape because sexual coercion is part of the way rape culture becomes normalised. 

Research on teenagers shows that girls experience sexual coercion regularly within their early relationships. They do not see this as rape and they do not understand these experiences as abnormal because they have nothing else to compare to. Heterosexual girls and boys are socialised to accept the idea that girls are the "gatekeepers" of male sexuality. Girls are put in a "no win situation" where if they don't have sex, they risk losing their boyfriends, who pressure them into sex. At the same time, if they don't carefully manage their sexual relationships, they will be seen as "sluts" or "too easy." Girls and boys see that it's a woman's role to keep boys' sexual desires in check; it's their job to say no; and they buy into the myth that once sex is initiated it's too difficult to say no (e.g. http://goo.gl/3DyPlN). 

At the cultural levels, rape is constructed as something that happens to women as they walk down the street at night, even though research shows that women are overwhelmingly raped and assaulted by intimate partners. Nationally representative data published by the Australian Bureau of Statistics finds that 17% of all Australian women aged over 18 have experienced sexual assault since the age of 15; this obviously does not include under-age girls (http://goo.gl/pXdIai).  Almost 88% of these incidents involved a man that the women knew, predominantly former partners, as well as friends, colleagues and family members.

Only 14% of these women reported incidents involving a partner to the police, and only 16% reported incidents involving a stranger. The main reason for not reporting rape and sexual assault is that the women thought others would perceive the event was "too minor" and they wanted to avoid being shamed. 

We need to move away from thinking that there are different "kinds" of rape, and see the connection between a culture of coercion and sexual assault.

My God It's Full of Stars

One of the more difficult ideas to grasp in astronomy is the sheer scale of the cosmos. Even as a professional in the field it’s much easier to focus on numbers and data than really step back and appreciate scale. Every now and then there is an image that forces you contemplate scale, such as the Hubble Ultra Deep Field. Now NASA and ESA have released a new image of the Andromeda galaxy. It is the most detailed image of Andromeda ever made,and you can check it out in this video.

The total image has about 1.5 billion pixels, and shows over 100 million stars across 40,000 light years. In the image you can see the brilliant swirls of Andromeda’s spiral arms, but when you zoom in the dusty swirls resolve into individual stars. A vast sea of stars.

Andromeda is relatively close by cosmic standards. It’s only 2.5 million light years away, which is why we can resolve the galaxy in such detail.  But this shows only the brighter stars of Andromeda. It’s estimated that Andromeda contains about a trillion stars, most of which are too small and dim to resolve in this image. We’re still only seeing a fraction of the stars in this galaxy.

As you look on this image, keep in mind that this is only part of a nearby galaxy. Our own galaxy would look similar, as would many others. It’s estimated that there are 100 billion galaxies in the visible universe. That’s more than 10 galaxies for every man, woman and child on Earth. Multiply this image by ten, and for all of it there is only one single human being. The same is true for every person on the planet.

Images such as these often give a feeling of smallness. Within the vast cosmos we are merely dust upon dust. But to me it demonstrates just how rare and wondrous each of us are. We can look on an image such as this, see the spirals of stars, and we can understand the cosmos.___Gigapixels of Andromeda [4k].
