Wayne Marinovich26,506Wildlife Photographers CircleWell, it has been over a year since I last shared my wildlife photographers circle. I have recently been through it, and dropped some folks who no longer seems to be posting. Whilst going though all the people, I realise just how many friends I have made in this online world. I look forward to meeting more of you in the flesh someday.Please feel free to share this with your followers (that is how this works after all). If you are not on here and are a keen amateur, semi-pro or seasoned pro, let me know and I will add you.  2014-05-23 08:07:52474938

David Bowden37,155Its been awhile....For over three years I collected and shared an exclusive B&W circle. This circle "was" one of the most shared on G+ for awhile. I would share it once a month with everyone as a part of my personal desire to share more quality B&W images and photographers. The requirement for being in this circle was that the photographer shot at least 60% B&W images (I tend to shoot 80%).There are some excellent photographers and friends here. I encourage you to take a look at their work. While I know that bulk circle sharing is a thing of the past or no longer the norm on G+ (which is a shame) I wanted to re-share a collection of truly inspirational people.You wont be disappointed. Re-share if you like their work</david>2014-05-06 23:16:1649012223

Justin Hill22,577338 Photographers :- Due to a post I saw float past in my stream today I am suddenly aware of the fact that I have not shared any of my circles for a very long time. So to rectify that here's my circle of photographers. If you are missing from this circle you are most probably in my other photography circle that is HDR based...if you are also missing from that one then I am sorry as I simply cannot add everyone that crosses my path or stream. Enjoy...2013-10-11 14:09:1333813311

Where I've Been.

I have been missing from plus for a bit now and a couple of you have kindly inquired as to my whereabouts.  I wanted to share a quick post and photo providing that answer.  My wife and I had our first child recently and I have cut back on a few endeavors, including plus, to adjust for his arrival.  I do plan on returning as time permits, but for the time being my posting will be limited.  Thanks for understanding.

Finally.

Happy New Year Everyone!

I have been hoping to photograph Snowy Owls for a few years now, but have come up empty.  This was finally the year and I was able to find a number of them over my Christmas vacation and get a few photos.  They are truly magnificent and it was special to see them in the wild.  I had as much fun observing them as I did photographing them.  I look forward to my next encounter with them, but for now will have to enjoy the photos I took of them.

Carry The One Radio: Tapping into the Brains Avoidance Centers.

Carry The One Radio:  Tapping Into the Brains Avoidance Centers
#ScienceSunday  

Check out +ScienceSunday's content partner, Carry the One Radio, and their new episode with Dr. Garret Stuber at UNC, Chapel Hill.

http://carrytheoneradio.com/episode/2014-02-01

The What - Traditionally, dopamine is known to transmit reward signals (food, sex, etc.) in the brain and promote behaviors that lead to that reward again. What you may not know, however, is that the area of the brain that releases dopamine, the ventral midbrain, also receives signals of aversion (things we find unpleasant or even dangerous) from a far-off brain region called the lateral habenula. These avoidance signals promote behaviors that lead us to avoid unpleasant or dangerous things in the world.

The Lab - These brain circuits are necessary for survival and are the focus of Dr. Garret Stuber and his laboratory at the University of North Carolina - Chapel Hill. Using a tool known as optogenetics, Dr. Stuber can excite specific populations of neurons within mouse brains and observe their effects on behavior. For example, by stimulating the neurons in the lateral habenula that signal aversion, he can cause mice to avoid the location in which they received that stimulation. He is essentially creating an aversive stimulus by stimulating the neurons that would normally respond to harmful or unpleasant cues in the world.

Why? - His work has important implications in addiction and psychiatric disorders

The Unexpected.

While out photographing Snowy Owls on Amherst Island this year, this hawk decided to get pretty close to me.  I always attempt to maintain my distance from the wildlife I photograph out of respect for them.  This hawk was not concerned about me and landed quite close to me.  I was appreciative of the great opportunity to get a close shot to this beautiful hawk.  You never know what to expect each day you go out to shoot, but I always enjoy it.  All in all, it was a great day of photography.

Cheers everyone.

Science in Action

I thought it would be fun to start snapping some photos of the science I'm doing on a daily basis. There are often cool visuals that we see everyday that you would never see unless you worked in a lab. This is a photo of our centrifuge as we purify plasmid for a lentiviral gene delivery experiment.

Carry the One Radio: Pulling DNA.

Check out the most recent edition of Carry the One Radio (content partner with +ScienceSunday) on Sophie Dumont's work at UCSF. Her lab is working to understand how the chromosome (an organized structure of DNA) is divided and segregated into separate daughter cells.

Carry the One Radio: Pulling DNA.

We bring you the newest interview by Carry the One Radio (brought to you by +Sama Ahmed) of Sophie Dumont at the University of California, San Francisco.

Find the episode here: http://www.carrytheoneradio.com/episode/2013-12-01

The Process - When a cell divides (called a parent cell), it provides a complete copy of genes to each new cell that is formed (called daughter cells). This complicated process occurs repeatedly to accomplish an organism's development, repair, and replenishment. To reliably split the DNA correctly requires an orchestra of microscopic interactions among many molecules.

The Mechanics - While we know many of the molecules involved, scientists still know relatively little about the mechanical interactions that underlie this process. Our guest this month, Sophie Dumont, Assistant Professor in the Department of Cell and Tissue Biology at UCSF, hopes to understand these interactions. Specifically, her lab is working to understand how the chromosome (an organized structure of DNA) is divided and segregated into separate daughter cells.

The Implications - Her work has implications in various developmental disorders and cancer, which can result from errors in cell division. At the end of our talk she discusses what it’s like to be a woman in science and gives advice to listeners interested in a career in science.

Mantis Eating a Fish

This really has to be seen to be believed. A mantis (probably a very hungry one) pounces on and eats an actual fish. Although, given that they are capable of eating birds, it's not altogether too surprising.

What's So Special About Science?

I love this quote out of the AAAS presidential address.

Knowledge is in every country the surest basis of publick happiness” - George Washington, first annual address to congress which you can find here, http://ahp.gatech.edu/first_state_union_1790.html

I also particularly like the concluding passage from the AAAS presidential address.

"The American public already highly values science and scientists and seems to have an intuitive grasp of heavy-tailed, not immediately monetizable, returns.

Through communication with the public, we must continue to provide the evidence that may justify those beliefs—indeed, this is the mission of AAAS. But also as individuals, we must seize every opportunity to demonstrate that what we do is altruistic and idealistic and that it is also economically vital. Our message is that science is a single, unified, long-term enterprise in which basic science discoveries, and research accomplishments of applied science and engineering, are things to be admired in their own right that also, often unpredictably, lead to better jobs and better lives, new products and new industries. Both of these perspectives will be well served if the United Statesis able to keep itself (and help to put the rest of the world) on a Solow-inspired trajectory of technology-enabled exponential growth."

Back Pain and Tissue Engineering

I have discussed my research using cell-based strategies to treat back pain a number of times on plus.  A recent Nature Outlook article discusses recent techniques to biologically repair and treat the diseased intervertebral disc.

(Note that the first picture is +Aubrey Francisco  one of our newest curators on +ScienceSunday !)  

Back Pain – Incredibly complex. This is probably the best way to start a discussion about this problem.  It is now ranked 6th in terms of disease burden according disability adjusted life years (http://www.ncbi.nlm.nih.gov/pubmed/23245608), ahead of malaria, diabetes, tuberculosis, lung cancer, and many other  diseases.  Despite the incredible disease burden, the underlying mechanisms that drive the development of chronic back pain are poorly understood.  One suspected contributor to back pain is degenerative disc disease.

Intervertebral Disc – The intervertebral disc is the cartilaginous tissue located within your spine that provides flexibility to your spine and acts as an energy dissipater (shock absorber).  Unfortunately, this tissue is susceptible to a process that leaves the tissue poorly hydrated, disorganized (it starts highly organized), and with a smaller height than in healthy tissues.  This is associated with altered mechanics, an inflammatory environment, disc herniation, and new nerve ingrowth into the disc.  These are all believed to contribute to the development of back pain in some patients.  I say some patients, because it is unclear to what degree each of these is contributing to back pain in each patient and there are many possible sources of back pain that are unrelated to the intervertebral disc.  In addition to functional changes in the intervertebral disc, growing evidence is implicating inflammatory signaling molecules and their interactions with pain sensing nerves (nociceptors) in and around the disc as a contributor to back pain (Disclaimer: this is my current research area and I have a vested research interest in these interactions).  For the fields current views on how the intervertebral disc is related to back pain, see the recently published review by Mak Risbud and Ivan Shapiro. 

(http://www.nature.com/nrrheum/journal/vaop/ncurrent/abs/nrrheum.2013.160.html)

Tissue Engineering - Due to the degeneration of the intervertebral disc, many efforts have been ongoing to restore mechanical function to the diseased tissue.  Some of these efforts have been non-biological in nature, such as total disc replacement efforts (http://www.synthes.com/sites/NA/Products/Spine/Interbody_and_Vertebral_Body_Replacement_Systems/Pages/ProDisc-C-Total-Disc-Replacement.aspx).  More recently, there has been a growing interest in biologically mediated efforts.  The most simplistic way of looking at these efforts is that new cells embedded in biomaterials, could develop and replace intervertebral disc tissue that has been damaged through disease progression.  These efforts are promising, but will likely evolve as our understanding of the underlying mechanisms of back pain change.  See the recent Nature Outlook article to hear from current opinion leaders in the field

The Growing #ScienceSunday Family
Welcome our newest curator, Aubrey Francisco

#ScienceSunday began just over two years ago, and we have been thrilled by the way it's become part of the fabric of Google+. We've now had over 150,000 page +s, over 80,000 circlers, and #ScienceSunday trends every week as people pass on their science-related stories, images, and even the occasional pun ;)

To keep up with the ever growing interest in science and +ScienceSunday on Google+, we have added our sixth curator to the #ScienceSunday family, Aubrey Francisco.

Meet Aubrey Francisco
Aubrey Francisco grew up in Amsterdam, NY and completed her undergraduate degree in Bioengineering at Syracuse University. She recently received her PhD in Biomedical Engineering from Duke University. Her doctorate work focused on the development of laminin functionalized biomaterials for cell-based regeneration of the intervertebral disc. During her undergraduate and graduate work, Aubrey developed a strong interest in science education and outreach through her experience as a teaching assistant and guest lecturer, and as a mentor for 8th grade girls interested in math and science. Aubrey recently relocated to the San Francisco Bay Area, where she hopes to start a career that combines her interests in science, education, and policy to help improve STEM education and scientific literacy.

The image shows Aubrey at work in the lab, working on a new biomaterial that could help millions of people around the world with back pain. You can read the full story on her work here: http://goo.gl/I6laJ2

Additionally, many reviewers contacted us saying they are ready and willing to do anything to get these reviews done. In light of this feedback, our review staff have risen to the challenge, and will be working with reviewers to go the extra mile in exceptionally creative ways to reschedule as many of the 200+ missed October review meetings as possible."

In other words, scientists with serious work loads are going to do whatever it takes to make sure the grants that were not reviewed, get reviewed ASAP.  The effects of the shutdown will continue to ripple through many communities, but I'm proud to be part of one that will go the extra mile to reduce the negative impact on research caused by the shutdown.

*The Science of The Zombie Brain 

Our new content partners at +ScienceSunday, Carry the One Radio, have produced a great podcast discussing the science of the brain through the eyes of the Zombie Brain.  It's a great bit of fun and I encourage you to check it out.

It's always great to see science being discussed in new and fun ways!

The Science of The Zombie Brain

Carry the One Radio, our newest +ScienceSunday  content partner,  brings us another fascinating podcast looking at the  science of brains through the lens of the  Zombie Brain!

Catch the podcast here: http://www.carrytheoneradio.com/episode/2013-10-31

The What - No, zombies are not real (at least not yet), but that does not mean we can’t enjoy analyzing their mental capacities.

The Who - This is the work of Brad Voytek, scientist at UCSF and our guest this month on Carry the One Radio. When Brad isn’t busy with his scientific research mapping the prefrontal cortex, the part of the brain that makes us human, he “studies” the effects of zombification on the brain. He uses this work as a fun way to teach neuroscience. Listen as Brad describes the zombie brain and how it can help us teach how the human brain might work.

*Keep tuning in for more great content from Carry the One Radio here at +ScienceSunday!

ScienceSunday Introduces Carry the One Radio.

ScienceSunday would like to introduce our new Content Partner, Carry the One Radio.  We will be carrying and sharing their short interviews with scientists .  We will be developing new content with Carry the One Radio to bring to you on a regular basis.   Please enjoy and share wide and far! 

The Interview - Samantha Ancona Esselmann interviews Dr. Mark Ansel (UCSF) to discuss the role of microRNAs in the immune system.  Dr. Mark Ansel is an Assistant Professor in the UCSF Department of Microbiology & Immunology and we discuss his work on these recently discovered molecules and their role in helping the body protect itself.

Immune System - The key to understanding our immune system might lie in understanding microRNAs. These are tiny strings of nucleotides (the same molecules that makes DNA) that influence how and which genes are expressed.

microRNA - Within the cell, most RNA is produced from our DNA (genes) and translated to make proteins that help the cell function. microRNAs are produced from DNA but don’t make proteins. Instead, microRNAs ensure that the right genes are translated under the right conditions.

Role in Immune System - microRNAs work in the immune system by helping a type of white blood cell, known as a T-cell, make antibodies that bind and destroy cellular invaders. The set of microRNAs that Dr. Ansel and his lab studies regulate genes that let T-cells recognize their environment and produce the correct antibodies. He has found that without these microRNAs, T-cells cannot properly mediate immunity.

Implications - Dr. Ansel's work has important implications in understanding the immune system and what  goes wrong in diseases like HIV and AIDS. At the end of our interview, he talks about what motivates him most in science—the thrill of discovery.

Music: Kevin MacLeod: J. S. Bach: Prelude in C - BWV 846

Two Egrets.

These beautiful Great Egrets did me a favor and set up in a spot that both put the background in relative shadow and direct light on them.  This allowed me to expose for them and their reflections and produce one of my favorite Egret shots in some time.  I would say I spend many hours per photo that I find acceptable.  This often involves sitting for a long time watching the light and scene for the right moment.  I love every minute of it!

Brain, Plumbing, and Sleep.

Researchers out of the University of Rochester have demonstrated that the glymphatic system, which you can think of as the brain's "plumbing" system, changes states during sleep.  The space between cells can increase by 60% when asleep or anesthetized!  This change allows molecules such as beta-amyloid, a molecule associated with Alzheimer’s, to be cleared more rapidly when asleep than awake!  This study helps provide a novel clue into the function of sleep.

The video below shows dye flowing through the brain when asleep (left) and when awake (right).  The increased flow and clearance described above can be observed with the increased flow nad clearance of the dye on the left!

Retrograde motion
When you plot the position of Mars in the sky, you’ll notice that in general it moves from West to East. But when we are closest to Mars, it seems to go backwards for a bit before continuing. This is called retrograde motion, and this challenged early models of the Solar system which had Earth at the center. The animation shows why Mars appears to go backwards for a bit.

This Great Egret just finished its morning fishing routine and was ready to perch in a nearby tree.  It's always a magnificent experience to spend extended time with an animal in the wild.  Often, you get a quick glimpse of an animal and they are off.  But this Great Egret remained fishing for about 2 hours while I photographed the bird.  A wonderful experience.

Pain is Good - Pain has largely developed to help provide a reflexive withdrawal from a harmful situation.  It helps you remove yourself form the situation, protect the affected region while healing, and promote avoidance in the future.  In fact, those who don't sense pain due to congenital defects have a shorter life expectancy!  *Edit:* +Rajini Rao pointed us to a specific mutation in a voltage-gated sodium channel (Nav1.7) that is preferentially expressed in afferent (sensory) neurons (http://knowingneurons.com/2013/09/25/a-world-without-pain/).  This mutation leads to a lack of pain sensation.

Pain can be Bad - Unfortunately, the pain response can become chronic and debilitating in some people.  We are especially aware of this phenomenon in lower back pain, which is the 6th most devastating disease in terms of loss of disability-adjusted life years!

Researchers are working hard to understand what causes chronic pain responses and how to treat and separate them from the appropriate and beneficial pain response.

At Home.

I'm always fascinated by the interaction between wildlife and their environment.  This Bison was at home resting on Antelope Island with the beautiful colors and patterns of the grass, beach, and the Great Salt Lake all around.  The Bison was introduced to Antelope Island in 1893 and has a population of around 550-700 on the island at this time.  The dry grass prairies provide a near optimum environment for the Bison.  It was a lot of fun being out in the island with these beautiful beasts and I look forward to spending more time on Antelope Island!

The Lake that Does Not Instantly Turn Birds to Stone

There have been some incredible images floating around the internet of animals that have been preserved by Lake Natron.  Unfortunately, some of the information and implications being spread with them are not quite accurate.

There is an implication that these birds are instantly turned to stone; however, this is simply not the case.  These birds are preserved over a much longer period of time.  Only birds that become immersed are preserved.  In fact there are birds that are perfectly capable of surviving in the lake.  It is the largest breading ground for North Africa's lesser flamingo.

It's also important to note that these animals were staged in these positions, as the photographer freely admits.  He simply found them washed up on the shore after being preserved in the lake.

It's Horribly beautiful!! wow!!

Any Animal That Touches This Lethal Lake Turns to Stone!

There's a deceptively still body of water in Tanzania with a deadly secret—it turns any animal it touches to stone. The rare phenomenon is caused by the chemical makeup of the lake, but the petrified creatures it leaves behind are straight out of a horror film.

Photographed by Nick Brandt in his new book, Across the Ravaged Land, petrified creatures pepper the area around the lake due to its constant pH of 9 to 10.5—an extremely basic alkalinity that preserves these creatures for eternity. According to Brandt:

"I unexpectedly found the creatures - all manner of birds and bats - washed up along the shoreline of Lake Natron in Northern Tanzania. No-one knows for certain exactly how they die, but it appears that the extreme reflective nature of the lake’s surface confuses them, and like birds crashing into plate glass windows, they crash into the lake. The water has an extremely high soda and salt content, so high that it would strip the ink off my Kodak film boxes within a few seconds. The soda and salt causes the creatures to calcify, perfectly preserved, as they dry.

I took these creatures as I found them on the shoreline, and then placed them in ‘living’ positions, bringing them back to ‘life’, as it were. Reanimated, alive again in death."

Who's More Pig-Headed, Dems or Republicans?  Science Attempts to Answer

An interesting study conducted during the 2012 election attempts to answer this question and provides some insight into the stalemate occurring with the government shutdown.  It appears that both sides have equal levels of "belief superiority", while conservatives tend to be more rigid in their belief systems.

The study was conducted during the 2012 election and may offer some insights into our current stalemate.  Study author Dr. Katlin Toner states that “Once people get into a position that they’re feeling superior about, it makes them unable to compromise.  Because if you believe you’re totally right, then why should you yield on anything?”

Scientists in the News Here on Google+!

One of the great things about google+ is the high quality and heavily engaged group of scientists that interact here.  The science we hear in the news is usually out of reach, but not on plus.  +Rajini Rao shares a post on a recent paper published out of her lab on NHE9 and Autism.

Don't miss this opportunity to read her post, check out the story (http://www.sciencedaily.com/releases/2013/09/130930114101.htm), and directly engage and ask her questions about her most recent findings!

#ScienceEveryday  

A Part of the Puzzle: NHE9 and Autism

❑ People with autism have difficulty with social interaction, language delay and stereotyped interests or repetitive behaviors that vary widely in severity between individuals. Currently diagnosed at rates of 1 in 88 children, autism spectrum disorders are an urgent public health issue. 

❑ Autism is one of the most inheritable of neurodevelopmental disorders. We know this from twin studies, family trees and rare chromosomal abnormalities. But it is also the most complex - because no single gene contributes to more than 1% of autism cases. We describe this as extremely heterogenic.  Most likely, these myriad genes impact a few common pathways, such as signaling between nerve cells. Although geneticists trawl through massive banks of DNA sequence and clinical data to uncover candidate genes, each one still has to be analyzed individually to separate the chaff from the grain- harmless variations in DNA (polymorphisms) from disease-causing mutations. 

❑ In a study just published we focused on a gene that had been flagged as a suspect in attention-deficit hyperactivity disorder, addiction and epilepsy as well as autism spectrum disorders. We knew that the gene made a transporter named NHE9, that shuttled positively charged particles of hydrogen, sodium and potassium into and out of cellular compartments called endosomes. By regulating the acidity inside these compartments, we showed that NHE9 controlled traffic to the cell surface and delivery of cargo (such as the neurotransmitter glutamate) critical for communication between nerve cells. 

❑ We drew upon decades of basic research in simpler models like bacteria and yeast to develop a structure of the transporter protein (inset in the image). To do this, we used evolutionary conservation analysis to predict if variants would be harmless or disruptive of the protein structure and function (simply, highly conserved portions of the protein are critical for function, whereas the more variable regions are often not). Using yeast as a model, we quickly (and cheaply!) screened through mutations to find those that resulted in loss of transport function. Then we extended our findings to the more complex neurobiological model: glial cells from mouse brains. We chose to study these cells because they are critical for mopping up neurotransmitter glutamate from nerve junctions, and we knew that patient brains showed elevations of glutamate, which tend to spark seizures. We hope this systematic screening process will be useful in the near future when gene sequences are routinely available for everyone, so we can determine risk levels in patients. Also, our study sheds a spotlight on the importance of trafficking in neurological disorders, that could be a target for future therapy.

Morning Flight.

I have been spending some time with the Great Egrets on Jordan Lake near Durham, NC recently.  It is wonderfully serene out there early in the morning with a number of egrets, herons, bald eagles, and osprey on the lake.  It is probably one of the few times I get to sit back and relax.  This Great Egret just finished catching a morning meal and was headed back to a tree to perch for a bit.  I spent about the 3 hours in total with this bird and enjoyed every minute.

We have seeded the cells in a collagen gel.  The cells attach to this collagen and then begin pulling on the the collagen fibers, visualize the cells pulling on interconnected tiny ropes.  As the cells pull on these ropes, they begin to contract the gel we have seeded them in.  They will pull on the collagen until the gel reaches high enough mechanical strength (the contracting of the gel increases its strength) to withstand the cells pulling on the ropes and the gell stops contracting.  After the cells have completed this process, the collagen has gone from randomly oriented fibers (tiny ropes) and aligned all the fibers in a single direction!  They are capable of modifying their environment in many ways, and this is just one of them.

Watch the gif and see if you can see how the cells and collagen have changed their structure due to the cells actions.___

Breakfast for One

I have been on a bit of a Great Egret kick recently.   I have been spending time down on Jordan Lake near Durham, North Carolina photographing these beauties.  I parked for a couple of hours this weekend on a favorite spot for them to fish hoping one would make an appearance.  I wasn't disappointed!  This one showed up and fished very patiently.  I had my focus locked on for about an hour before the strike.  I was starting to cramp up!  

This shot is immediately after the fish was plucked from the water.  You can see the water droplets around the face from the fresh capture.  I cropped down from the photo I posted on my website (http://www.robbybowles.com/Art/Wild/i-wJVwHFb/A) so that it would be easier to see the action.

I have been on a bit of a Great Egret kick recently.   I have been spending time down on Jordan Lake near Durham, North Carolina photographing these beauties.  I parked for a couple of hours this weekend on a favorite spot for them to fish hoping one would make an appearance.  I wasn't disappointed!  This one showed up and fished very patiently.  I had my focus locked on for about an hour before the strike.  I was starting to cramp up!  

This shot is immediately after the fish was plucked from the water.  You can see the water droplets around the face from the fresh capture.  I cropped down from the photo I posted on my website (http://www.robbybowles.com/Art/Wild/i-wJVwHFb/A) so that it would be easier to see the action.

3D Printed Food!

Hod Lipson, a Professor at +Cornell University, produces a 3D printed meal.  This included the food, silverware, and all.  I actually worked in an adjacent lab during my time at Cornell and Hod Lipson's lab was responsible for 3D printing a number of molds I used in my research.  I remember when they first started working to 3D print food and it's cool how far they have taken it at this point.

What do you think?  Would you eat 3D printed food?

Fall Begins.

It's always great when the colors begin to change and you can start including them in your photos.  This Great Egret here on Jordan Lake perches against the backdrop of the first sign of color change.  I often go out looking for Bald Eagles to photograph on the lake, but I really should spend more time on these beautiful birds.

Afternoon Nap.

It's been a long time since I shared a photo for #WildlifeWednesday, as I have been busy with work.  However, today I wanted to share a photo of a Bison on Antelope Island near Salt Lake City, which is soon to be my new home!  Looking forward to all the great photo opportunities out there!  And hopefully many more #WildlifeWednesday's to come.

Knee Rainbow Fail: Be Willing to be Wrong
#ScienceSunday (curated by +Allison Sekuler, +Rajini Rao, +Chad Haney, +Rajini Rao, and +Robby Bowles) 

This is a failed experiment and they happen all the time in science.  In fact I spend most of my time "failing".  But the great thing about science is that we check to make sure what we are seeing is real, and not a byproduct of our experiment.  We run controls to confirm our experiments are real phenomena.  

So the beautiful photo you see here, did not tell me what I had hoped.  However, it's better to know you are wrong, than assume you are right.  You can do great damage assuming you are correct.  

Be willing to be wrong, you may be surprised where it leads you!

Evening Light

It has been an incredibly busy 6-8 months with a new baby and the very grueling faculty job search that started in the Fall of last year.  As a result, I haven't been posting much or using plus as much as I would like.  I'm trying to ease my way back into it.  Here is my first photo in quite some time from a recent trip to Salt Lake City.  This photo was taken about 2 hours north on Bear Lake.  My newborn waited patiently with my wife for about 10 minutes while I sped through setting up the shot and getting back into the car before he awoke.  Mission accomplished!

New Biomaterials for Disc Regeneration

A recent study that I was involved in shared by +Duke University.  In this work a graduate student in my lab designed a new biomaterial to promote regeneration of the nucleus pulposus.  This is the inner region of the disc that is responsible for resisting the compressive forces experienced in your spine.  As you can imagine, this tissue is quite important and the hope is to restore it to its pre-diseased state by injecting cells embedded in biomaterial carriers.

Induro Love.

The Induro blog covered our nature photography today!  Always fun to get a little exposure :).  We haven't been able to get out to do any photography recently with the newborn, but hopefully it won't be too long!

I really do recommend the Carbon CT series of tripods, they provide great stability and ease of use.

Posts Worth Spreading.

Check out +Mark Bruce's most recent edition of SciTech #ScienceSunday  Digest.  As always, it contains a number of exciting scientific breakthroughs from the previous week!  Check them out, I guarantee you won't be disappointed. 

SciTech #ScienceSunday Digest 11 - 17th Mar 2013
Standard genetic parts, graphene speaker, hair-thin endoscope, self assembling tissues, true nanocomposites, robotic cloud, and more.

1. A Precision Genetic Grammar for Engineering Cells.
A research group / company called BIOFAB has launched an online shop for a library of standard biological parts that it has created http://www.nature.com/news/dna-tool-kit-goes-live-online-1.12585. These standard biological parts - DNA sequences - allow precise control of gene activity in the bacterium Escherichia coli  and should allow biologists to design bigger and more complicated circuits and engineer cells that can make medicines and perform other useful tasks simply by plugging in various sets of genes. The sequences overcome a significant barrier in synthetic biology in which genes inserted into an organism often do not behave predictably. Where previously biologists had a 50% chance of making a cell express a protein at a certain level, these new parts minimise downstream disruptions and result in a 93% chance of doing so. But there is still a way to go “before in silico designs of genetic circuits can be popped into a cell and run like an app.”

2. Loudspeakers Driven by Graphene Diaphragm.
Researchers have created an earphone-sized speaker that utilises a graphene diaphragm that, even without any specialized acoustic design, performs comparably to a high quality commercial headset http://www.technologyreview.com/view/512496/first-graphene-audio-speaker-easily-outperforms-traditional-designs/. When the electric field in the speaker oscillates this causes the graphene to oscillate in turn, which generates surprisingly high-quality sound. Perhaps unsurprisingly this is all due to graphene’s key properties of thinness and strength, which enables such high performance without the need for costly and complex damping engineering of the device, and results in the diaphragm converting most of its energy into sound. I’m left wondering if (i) they can get it to work in reverse to harvest vibrations from the environment to produce electricity, and (ii) they can scale it up to larger-size speakers for use in large displays and walls?

3.  Engineering a Hi-Res Endoscope as Thin as a Human Hair.
An endoscope as thin as a human hair and with resolution four times better than related devices has been developed by Stanford engineers http://engineering.stanford.edu/news/high-resolution-endoscope-thin-human-hair. The device currently has a resolution of 2.5 micrometers and should reach 300 nanometers in future; it has been designed for minimally-invasive bioimaging. One of the limitations is that the endoscope must remain rigid as the distortions from bending distort the image and information beyond recognition; nevertheless the team plans to attempt to engineer in flexibility to the fiber in future. So will we see this device being used in future brain computer interfaces and optogenetics? 

4. LEGO-Inspired Tissue Engineering.
Tissue engineers have developed a new “plug-and-play” method to assemble complex cell microenvironments in a scalable, highly precise way to fabricate tissues with any spatial organization of interest — such as those found in the heart or skeleton or vasculature http://www.kurzweilai.net/designing-interlocking-building-blocks-to-create-complex-tissues. The lock-and-key technique can be used to build cellular assemblies using a variety of shapes just a fraction of a millimeter in size that lock into templates like LEGO building blocks. The tiny building blocks are made with standard fabrication techniques and contain living cells and desired molecules and the assembly technique is simple: a mixture of various types of shapes is placed onto a template and shaken for a few minutes during which each shape can dock only into its matching well - after several cycles the template becomes filled with shapes to form a precisely defined pattern, and so a large number of subunits forms into new tissues. Controllable self-assembly of macro-scale tissue structures = very cool. 

5. Nanocomposite Macromaterials Finally Benefit from Nanomaterial Properties.
Researchers have finally managed to create composite materials that actually match the strength and flexibility of the nanowires that have been placed inside them http://spectrum.ieee.org/nanoclast/semiconductors/nanotechnology/researchers-cross-the-valley-of-death-in-nanocomposite-design. Previously, promising nanomaterials have been added to composites in order to improve their material properties for a range of applications but in general failed to produce materials with the desired properties, due mainly to the other materials in the mix. The group has managed to get around this limitation by using a shape-memory alloy (nickel-titanium) that had enough elasticity to be used with nanowires in a material matrix without losing the superior functionality of the nanowires. The shape-memory alloy can deform enough to give the nanowires a chance to do their job and bear bear the high load. This particular composite is twice as strong as high-strength steel while managing an elastic strain limit up to 10 times greater. We also had stronger, light-weight magnesium alloys http://news.ncsu.edu/releases/wms-zhu-mg-alloy-2013/. 

6. A Cloud Computing Platform for Robots.
A large European research effort has launched the RoboEarth Cloud Engine, a cloud-computing platform for robots http://www.alphagalileo.org/ViewItem.aspx?ItemId=129194&CultureCode=en. The Cloud Engine is designed to allow robots connected to the Internet to directly access the powerful computational, storage, and communications infrastructure of modern data centers for the purpose of robotic tasks and robotic learning. Jokes about Skynet aside the system should allows robots with a wireless connection to perform complex functions like mapping, navigation, or processing of human voice commands in the cloud, at a fraction of the time required by onboard computers and will help pave the way towards lighter, cheaper, more intelligent robots. On a personal note I did have a chuckle at the final sentence in this release “robots don’t kill jobs but rather tend to lead to an overall growth in jobs” - their PR person is staying on message it seems ;-) 

7. Smallest NanoElectoMechanical Vibration Sensor.
Researchers combined a carbon nanotube with a magnetic molecule to create a novel nanoelectomechanical system http://phys.org/news/2013-03-smallest-vibration-sensor-quantum-world.html. When an external magnetic field is applied the spin of the molecule is flipped and this results in a recoil being transferred to the carbon nanotube, which starts to vibrate; it is this vibration which changes the atomic distances of the tube, thus its conductance can be used as a measure of motion. Aside from accurately measuring nanoscale magnetic forces the system could also be used for determining the mass of individual molecules and also possibly as a qubit. 

8. Electronic Sensor Tattoos Printed Directly onto Skin.
Researchers have developed a method to print flexible electronic sensors directly onto skin http://www.technologyreview.com/news/512061/electronic-sensors-printed-directly-on-the-skin/; the devices consist of ultrathin electrodes, electronics, sensors, and wireless power and communication systems. The researchers also found that they could use commercially available “spray-on bandage” products to add a thin protective layer and bond the system to the skin in a “very robust way. The device attaches to the skin and can measure things like temperature, strain, and the hydration state of the skin and these measurements can be recorded and transmitted for medical purposes. One application would be monitoring healing near the skin’s surface, as in the case of surgical wounds, and it can be worn for up to two weeks before the skin’s natural exfoliation process causes it to flake off.

9. Room Temperature Electrically Powered Nanolasers.
An electrically powered nanolaser has been designed that circumvents previous problems of requirement for a larger light source and overheating http://spectrum.ieee.org/nanoclast/semiconductors/nanotechnology/electrically-powered-nanolasers-capable-of-being-operated-at-room-temperature. The group “shows for the first time that metal heating loss is not an insurmountable barrier for room-temperature operation of a metallic cavity nanolaser under electrical injection.” By enabling a room temperature electrical capability the device could play an important role across electronics, with nanolasers that speed up computers, broaden Internet bandwidth and serve as light sources for computer-chip-based sensing technologies that are integral to embedded computing.

10. Breaking 10% Efficiency for Organic Photovoltaics.
The benefits of organic photovoltaics are their low cost and low weight, but if they are ever to deliver on the promise of cheap solar power they need to break the 10% energy efficiency benchmark. With this in mind a group has developed a design for plasmonic-assisted organic photovoltaics that should break this 10% efficiency http://www.nanowerk.com/spotlight/spotid=29503.php. Their proposal exploits the benefits of using various plasmonic nanostructures for broad-band, polarization-insensitive and angle-independent absorption enhancement, and their integration with one or two electrode(s) with an organic photovoltaic device. These plasmonic nanostructures are comprised of arrays of metallic nanoparticles that can be randomly distributed or aligned in periodic arrays - now they just need to build the thing to prove that it works.

Organs and tissue are incredibly complex in terms of their cellular and material components.  An orchestra of cell signaling and material architecture is necessary to produce and maintain function of these complex tissues.  Therein lies one of the great challenges in tissue engineering and growing new organs.  How can we create these complex tissues in the lab?  A paper recently published in PNAS (http://www.pnas.org/content/early/2013/02/27/1300569110) may provide one key tool to help create these complex structures.

Legos – The concept has been around for a long time in the form of a favorite childhood toy of many.  The researchers at Columbia University have created very small building blocks of multiple shapes that allow complex components to be built up to help create complex organs.  The key here is the ability to incorporate different cells and/or different molecules within these blocks.  Complex organization and cell signaling can be obtained by placing varying blocks in proximity to one another.  One can easily see how patterning these blocks could help create a complex tissue.  Additionally, this technology can help us understand how cells interact spatially with one another in a more complex manor than has traditionally been obtained in tissue engineered tissues.

Hydrogels – The researchers used a material called a hydrogel, and traditional computer-chip-fabrication technologies to produce the building blocks.  A hydrogel is a network of polymer chains that is hydrophilic (it “likes” water).  This material is often used in tissue engineering because it is often biocompatible, very cell friendly, and easily obtained and manipulated.

Future – The researchers will now continue to use these blocks to study cell signaling and tissue development.  And who knows, maybe you will see lego-like tissue-engineered organs helping to treat human disease soon!___

An intriguing paper was recently published in PNAS (http://www.pnas.org/content/early/2013/03/06/1218772110.full.pdf+html) on the ability to predict personal and private traits from facebook likes.

A direct quote from the paper states "We show that a wide variety of people’s personal attributes,ranging from sexual orientation to intelligence, can be automatically and accurately inferred using their Facebook Likes."

It is important to note that the statistical techniques used are not particularly complex.  This makes similar methods fairly easy to employ if one has access to the data.  With more and more of our lives being made available online through our own actions on social media, this almost seems inevitable.

Will this cause you to change any of your online behavior?  Does it concern you?___

Man has 75% of Skull Replaced!

Now this is just cool and amazing.  3D printing was used to replace 75% of a man’s skull!!

3D Printing - The technique used here was similar to a tissue engineering article I recently posted about (https://plus.google.com/u/0/114146479114949843175/posts/RvjmfiwN2or).  The patient had their head scanned and then that data used to produce a CAD (computer aided design) file.  This file was imported into a 3D printer, which then produced an implant layer-by-layer with the correct topology to match the patient’s skull!  This patient specific technology can dramatically improve implant fit and outcome.

PEKK  -  The material used for the printing was a thermoplastic, polyetherketoneketone (PEKK).  Thermoplastics are polymers that soften above a certain temperature but harden once cooled again.  This property allowsthis materi... more »

PEKK  -  The material used for the printing was a thermoplastic, polyetherketoneketone (PEKK).  Thermoplastics are polymers that soften above a certain temperature but harden once cooled again.  This property allows this material to be 3D printed for this purpose.  Other extremely important properties of PEKK for this application are its biocompatibility and similar mechanical properties to bone.  Matching mechanical properties to bone is extremely important for implants interfacing with bone!  If too stiff, the patient will experience bone loss and eventual implant loosening and failure.  But if the implant is not stiff enough, the implant may fail to provide the protection and withstand the forces placed upon it.  Biomedical engineering is a tricky business!

Future - 3D printing and PEKK are sure to have a huge impact on the biomedical world, especially orthopaedic applications.  It will be amazing to see where we go from here!

Mysterious Notochord

I’m sharing this beautiful image from a paper recently published in the Journal of Cell Biology (http://jcb.rupress.org/content/200/5/667) on the notochord and it’s role in spine morphogenesis.  Now you may be asking why this would be of interest to you.  The reason is simple, back pain is a huge problem, it dramatically reduces our quality of life and has huge societal costs.  The cells studied in this paper (notochordal cells) may be playing a significant role in the development of back pain.  Here is why.

I’m sharing this beautiful image from a paper recently published in the Journal of Cell Biology (http://jcb.rupress.org/content/200/5/667) on the notochord and it’s role in spine morphogenesis.  Now you may be asking why this would be of interest to you.  The reason is simple, back pain is a huge problem, it dramatically reduces our quality of life and has huge societal costs.  The cells studied in this paper (notochordal cells) may be playing a significant role in the development of back pain.  Here is why.    

The Intervertebal Disc - The intervertebral disc is a cartilaginous tissue found in your spine, which is believed to play a role in the development of back pain when injured or diseased.   This disc is responsible for providing motion to your spine, as well as acting as a shock absorber in your spine.  It’s incredibly integral to our daily experience, but can be very painful when things go wrong.

Notochordal Cells - An interesting feature of the intervertebal disc is the presence of vacuolated cells in the IVD (generally called notochordal-like cells).  However, we lose these cells as we age, and by the age of 11, they are gone.  Some animals never lose these cells, including some dogs, and the ones that do not generally don’t suffer from disc disease!  However, we still don’t know a whole lot about these cells, and is why papers such as the on just published is so important.  It may lead to novel understanding of how these cells are functioning and how we can intervene in the development of back pain.

Use in Regenerative Medicine - There is a lot of interest in using this cell type to aid in regenerative medicine strategies to treat disc disease, but there is a problem.  They are gone by the age of 11, so they would be difficult to obtain when the patient is suffering from back pain, which is generally much older than 11.  As a result, a number of scientists are interested in developing notochordal-like cells from stem cells in order to deliver them later in life and return the diseased IVD to a more healthy state.  

The Future - The real breakthrough would be the development of technologies to intervene much earlier in life and prevent disc disease all together.  This is why advancements such as those presented in this paper are integral to helping us understand these mysterious cells, their role in spinal development, their role in the development of spinal pathology, and how they may be harnessed to relieve your aching back!___
