Science on Google+610,661Data blitz is a new hangout (not Hangout On Air), which is hosted by the Science on Google+ Community (http://goo.gl/uhJCN). This monthly hangout will start at 10:00 PM (EDT) on the second Wednesday of each month, and the main goal is to create a platform so researchers can get feedback on their _hot off the press_ research findings and discuss other issues in research, funding, and publishing. There are only two rules. First, to keep things moving, presentations cannot exceed one slide! Second, due to the 10 person limit of hangouts, all individuals who join the hangout will be expected to contribute to the discussion by presenting research or research related issues. RSVP “yes” if you want an invite for the next Science on Google+ Data Blitz.Science on Google+ Data Blitz2013-10-10 04:00:0052

Today is International Day for the Elimination of Violence against Women

Today is International Day for the Elimination of Violence against Women "Combating all forms of violence against women and girls is a fundamental pillar of the respect for human or fundamental rights and remains a priority for the EU, both internally and externally," said in a statement Federica Mogherini, Neven Mimica and Věra Jourová (read it whole: http://europa.eu/!pM33tn)

From today until Human Rights Day on December 10, all EU Delegations around the world will also join the '16-days of Activism against Gender-Based Violence' international campaign by United Nations. Will you take part? http://bit.ly/1r8cLUe

"If the results can be replicated reliably and scaled up — and that's a big "if," since NASA only produced them on a very small scale over a two-day period — they could ultimately result in ultra-light weight, ultra fast spacecraft that could carry humans to Mars in weeks instead of months, and to the nearest star system outside our own (Proxima Centurai) in just about 30 years."

The triviality of this statement is more telling than the statement itself:

“Any creatures who will be alive to witness the death of the sun won’t be human— they could be as different from us as we are from protozoa. Indeed future evolution is going to take place not on the Darwinian time scale, of natural selection, but on the technology time scale, because we’re obtaining the capacity to modify the genome.”

No more restrictions on what name you can choose on Google+. Well. Finally.

When we launched Google+ over three years ago, we had a lot of restrictions on what name you could use on your profile. This helped create a community made up of real people, but it also excluded a number of people who wanted to be part of it without using their real names. 

Over the years, as Google+ grew and its community became established, we steadily opened up this policy, from allowing +Page owners to use any name of their choosing to letting YouTube users bring their usernames into Google+. Today, we are taking the last step: there are no more restrictions on what name you can use. 

We know you've been calling for this change for a while. We know that our names policy has been unclear, and this has led to some unnecessarily difficult experiences for some of our users. For this we apologize, and we hope that today's change is a step toward making Google+ the welcoming and inclusive place that we want it to be. Thank you for expressing your opinions so passionately, and thanks for continuing to make Google+ the thoughtful community that it is.___No more restrictions on what name you can choose on Google+.

In a genome-wide analysis, scientists from University of California-San Diego and Yale found that we are far more genetically similar to our friends than we are to strangers of the same population. In fact, researchers say our friends are as “related” — genetically speaking — as fourth cousins. Their findings suggest that, in addition to our physical and biological environment, our social networks also play an important role in human evolution.

Gordian (un)knots

The Gordian knot was a famously intricate knot attached to a sacred ox cart in the ancient city of Gordium, near Ankara in modern-day Turkey.

In 333 BC, Alexander the Great attempted to untie the knot, but was unable to find the ends of the knot in order to do so. Instead, he is said to have undone the knot using what is now called the Alexandrian solution, which was to cut the knot in half with his sword.

Although there is good historical evidence that Alexander undid the Gordian knot, sources differ on how he accomplished this. According to some accounts, a more plausible theory is that he undid the knot by first removing the pin around which the knot was tied. This might have exposed the two ends of the knot, making it much easier to untie.

According to some accounts, a more plausible theory is that he undid the knot by first removing the pin around which the knot was tied. This might have exposed the two ends of the knot, making it much easier to untie.

Another possibility is that the Gordian knot did not have ends, and was a knotted loop instead of a knotted open piece of rope (or, in this case, bark). In other words, the Gordian knot might have been what mathematicians refer to as an unknot.

More precisely, an unknot is a (possibly knotted) closed loop that can be disentangled (i.e., continuously deformed) into a closed loop with no knot in it, without cutting the knot in the process. The branch of mathematics that deals with concepts like these is known as knot theory. Knot theory can cast light on scientific applications, for example the ways in which long organic molecules such as DNA can form tight coils.

The animation shows a good example of an unknot. However, the knot in the picture is made out of a very stretchy and almost frictionless material, unlike any material that a physical knot would likely be made out of.

What this means is that there may exist “Gordian” unknots which can be disentangled to the unknot in theory, but which cannot be disentangled in practice because of physical limitations of the material. Cutting the knot, or altering it in other ways (for example by soaking it) is considered cheating. The unknot in the animation is thought to be an example of such a Gordian unknot, but it seems that nobody has yet proved this rigorously.

New DNA. New letters/nucleotides

"When biologists talk about the letters in the DNA alphabet, they are actually talking about nucleotides: molecules that bind together to make up the DNA double helix. Normally, these molecules are made up of four letters: A,T, C and G. But scientists at the Scripps Research Institute have managed to add a single pair of artificial "X" and "Y" nucleotides to the genetic code of an E. Coli strain, reports The New York Times. And thus far, the bacteria appear to be reproducing normally and passing on the new X-Y pair to their offspring."

The 117th Element

"After four years of painstaking research, the discovery of the periodic table's 117th element has been confirmed. Element 117, otherwise known as ununseptium, was originally discovered back in 2010 by a group of American and Russian physicists with the Joint Institute for Nuclear Research (JINR). However, it has taken years for the discovery to be replicated by another independent team, which the International Union of Pure and Applied Chemistry (IUPAC) requires. Now the element, with the approval of the IUPAC, can be named and added to the periodic table, extending our understanding of transuranium elements."

Mice fear man, but not women

"People have not paid attention to this in the entire history of scientific research of animals," says Jeffrey Mogil, a pain researcher at McGill University and lead author of the study. "I think that it may have confounded, to whatever degree, some very large subset of existing research*."
That's why a new study in which researchers found that mice actually fear men, but not women, has the potential to be so disruptive.
Previous results reflect this male-induced stress effect — and they know nothing about it.

Well... Another theory.
"Now, physicists are unmasking a more fundamental source for the arrow of time: Energy disperses and objects equilibrate, they say, because of the way elementary particles become intertwined when they interact — a strange effect called quantum entanglement.
“Finally, we can understand why a cup of coffee equilibrates in a room,” said Tony Short, a quantum physicist at Bristol. “Entanglement builds up between the state of the coffee cup and the state of the room.”

"Contrary to popular belief, the presence or absence of certain sex organs isn't the determining factor when deciding which animal of a species is female and which is male. In fact, biologists don't use sex chromosomes either. They actually rely on the size of an animal's gametes — sperm in males and oocytes in females. As the rule goes, females are the sex that contribute the largest gametes, whereas males are the sex that contribute the smallest gametes and therefore expend the least amount of energy on producing these cells. So, in this particular instance of sex-role reversal, the convention still applies: the female in these species of insect produces the largest gametes — egg cells. She simply also happens to sport a penis that she introduces into the male's vagina during copulation."

Land Rover's new concept would give drivers a better view of the road through augmented reality. "The Transparent Bonnet Concept utilizes cameras mounted in the car's grille to capture a view of the road that's usually obscured by the hood. This data is then fed to a heads-up display that shows the video in real-time at the bottom of the windscreen, overlaying where a driver sees their car's bonnet and effectively giving the impression that it — and the engine — are transparent."

Until recently, researchers had been incapable of constructing one of the most emblematic symbols of our own genetic makeup: the eukaryotic chromosome. Now, a team of scientists has announced that the age of the synthetic chromosome is upon us, as a study published in Science today reveals how the group was able to construct a yeast chromosome from scratch — an experiment that allowed the team to make fully functional "designer yeast". ... "I think we will see all kinds of biosynthetic products made in bacteria and yeast over the next 10 years"

Mugshots from DNA

"Researchers at Penn State and the Catholic University of Leuven (KUL) created a statistical model for mapping accurate facial structures using racial, gender, and genetic markers. It's hoped that the model not only be used for forensic analysis, but also for creating a clearer picture of humanity's ancestors."

Major announcement coming...

...That much is clear, from this press release: on Monday at noon Eastern time, astronomers will “announce a major discovery.” No evidence from that page what the discovery actually is. But if you’re friends with a lot of cosmologists on Facebook/Twitter (or if you just read the Guardian), you’ve heard the rumor: the BICEP2 experiment has purportedly detected signs of gravitational waves in the polarization of the cosmic microwave background radiation. If it’s true (and the result holds up), it will be an enormously important clue about what happened at the very earliest moments of the Big Bang.

Physics & Apps. Useful and Fun for Android and iPhone

Symmetry scoured the app stores and pulled out a few of our favorites. These apps stretch the scale from massive galactic phenomena to subatomic particles, and send you on adventures ranging from Ms. Particle Man's fictional pursuit of the Higgs boson to the actual particle pathways that led to its discovery at the Large Hadron Collider.

Watch Live as an Asteroid Hurtles By Earth Later Today

On Wednesday, an 82-foot asteroid barreling through space at 33,000 miles per hour will pass Earth within the moon's orbit, or about 216,000 miles. Astronomers say there’s no chance it will hit us, but you could catch on live video the galactic flyby via webcast.

120 computer-generated papers found/withdrawn

"Two science publishers have withdrawn more than 120 papers after a researcher in France identified them as computer-generated. According to Nature News, 16 fraudulent papers appeared in publications from Germany-based Springer, and more than 100 were published by the New York-based Institute of Electrical and Electronic Engineers (IEEE). The papers were flagged by computer scientist Cyril Labbé, of Joseph Fourier University in Grenoble, France. They were created using software called #SCIgen, which was invented by MIT researchers in 2005 to prove how easy it is to publish nonsense papers in conference proceedings. Labbé developed a way to identify the papers by recognizing common words that SCIgen uses, as described in a 2012 study...."

Non-human mathematics: If we can't check the proof, is it valid?

"Paul #Erdős in the 1930s: he imagined an infinite sequence of numbers containing nothing but +1s and -1s, and he wanted to see the sequence's capacity to contain internal patterns. He came up with a way of measuring this by cutting the infinite sequence at a point and creating smaller subsequences within it (such as considering only every third or fourth number)."
Erdős' main hypothesis was that a discrepancy of any value can always be found, but he was never able to prove it. Now a computer has solved it, but "It raises the question of non-human mathematics: if a proof can only be checked with a computer, can it be accepted as true by humans?"

NOvA experiment sees first long-distance neutrinos

Scientists on the world’s longest-distance neutrino experiment announced today that they have seen their first neutrinos. Billions of those particles are sent through the earth every two seconds, aimed at the massive detectors. Once the experiment is fully operational, scientists will catch a precious few each day.

Quarks & symmetry

"From matching wings on butterflies to the repeating six-point pattern of snowflakes, symmetries echo through nature, even down to the smallest building blocks of matter. Since the discovery of quarks, the building blocks of protons and neutrons, physicists have been exploiting those symmetries to study quarks’ intrinsic properties and to uncover what those properties can reveal about the physical laws that govern them."
