Light-Activated, Injectable Gel Could Help Build New Faces | 80beats

gel
Before LED light is shined on it, the injected gel is still fluid and
can fill up any gaps of spaces under the skin.

What’s the News: Scientists have developed a gel that could be used to rebuild the faces of crash victims. Activated by light, it solves several of the problems inherent in the usual methods.

What’s the Context:

Dealing with damaged soft tissue is often more complex than dealing with damaged bone and skin. The shape of someone’s face is dependent on the fat, muscle, and other tissue below the surface, and doctors trying to restore someone’s facial structure must contend with scar tissue, swelling, and loss of movement.
Current methods include injecting hyaluronic acid (HA), a naturally occurring molecule that helps thicken the gel that surrounds cells in the body, or synthetic materials, but both of these have their issues: HA injections don’t last, and synthetic materials can cause inflammation. Grafting soft tissue from other parts of the body is also an option, but that can cause scar tissue to form where it was removed and at the graft site.
Additionally, it’s not possible to control the shape of the synthetic materials after they’re ...


Extroverted Elephants Change Their Best Friends Over Time | Discoblog

spacing is important

While there are many different specific personality types, people are often categorized as either introverted or extroverted. Some like to keep to just a few close friends, rarely leaving their small comfort zones, while others are more outgoing, collecting friends wherever they go; most of us fall somewhere the middle. But we’re not the only mammals with this type of social diversity. Researchers in Sri Lanka have now found that many female Asian elephants—previously believed to be kind of antisocial—are social butterflies, changing their circle of friends as the seasons pass. Moreover, they maintain close ties with pals even after extended periods of separation.

In an Asian elephant society, females and calves stick together in groups of a few individuals, called herds, while males roam about more independently, doing male things. These small bands are part of much a larger group. In the new study, published in the journal BMC Ecology, researchers wanted to see how the relationships of individual female elephants changed over time, so they stalked nearly 300 pachyderms for five seasons in the Udawalawe National Park in Sri Lanka.

As expected, Shermin de Silva, a behavioral ecologist at the ...


Memory improves when neurons fire in youthful surroundings | Not Exactly Rocket Science

As we get older, our memories start to fail us. The symptoms of this decline are clear, from losing track of house keys to getting easily muddled and confused. Many of these problems stem from a failure of working memory – the ability to hold pieces of information in mind, block out distractions and stay focused on our goals. Now, a team of American scientists has discovered one of the reasons behind this decline, and a way of potentially reversing it.

Our working memory depends on an area known as the prefrontal cortex or PFC, right at the front of the brain. The PFC contains a network of nerve cells called pyramidal neurons that are all connected to one another and constantly keep each other buzzing and excited – like a neural version of Twitter. This mutual stimulation is the key to our working memory. As we age, the buzz of the pyramidal neurons gets weaker, and information falls more readily from our mental grasp.

But this decline isn’t the fault of the neurons themselves. By studying monkeys, Min Wang from the Yale University School of Medicine has found ...

It’s official: we’ve moved to open.nasa.gov

It was February 2008 when I posted my first article on opennasa.com! So much has changed both at NASA and in the world since then. We originally launched opennasa.com because we were a group of people extremely passionate about space exploration that wanted to share, first hand, our perspective of what was happening inside the U.S. space program. We started a conversation that lasted 3.5 years. 277 posts, 5,274 comments, 347 tags and an average of ~54 unique visitors per day.  It’s been such an amazing adventure.  We have really appreciated the conversation and the #opengov community that has formed within the space industry since then.

Yesterday we launched open.nasa.gov. Like openNASA, the new site will be a collaborative platform for the open government community to share success stories and projects they are working on. We are excited to finally have a home on nasa.gov and look forward to highlighting the ways that transparency, participation, and collaboration are being embraced by NASA policy, technology, and culture and discuss the amazing future that becomes possible because of that commitment.

Content from authors who will participate in the new open.nasa.gov site will be ported over, but this site will remain online and serve as an archive for the content from all those who have contributed to the project.  We have a lot planned for the new site, and anticipate it will be an even more successful project than openNASA.  We encourage you to check out the new site and let us know what you think! See you at nasa.gov.

Dear NASA Folks: Show Up For Work, Please

Message from the NASA Administrator 29 July 2011

"As you know, Congress is debating how it plans to meet its obligations and raise the debt ceiling so that the country can pay its bills. The President expects that Congress will do its job, enact an increase of the debt ceiling that he can sign into law, and end this impasse. I am sending this note to remind you that NASA employees should plan to come to work next week, as scheduled, at their normal place and time."

Poll Suggests Public Concern Over Direction In Space

IBOPE Zogby Poll: Six in 10 Disagree With Ending Space Shuttle & Fear Others Will Surpass U.S. in Exploration

"Majorities of U.S. voters disagree with the decision to end space shuttle missions and fear other nations might surpass the U.S. in space exploration. Also, future space exploration through both NASA and private companies is seen as preferable to either going it alone. The IBOPE Zogby interactive poll conducted from July 22-25 also shows 74% say the space shuttle was a worthwhile use of government resources. The final space shuttle mission ended with the safe landing of the Atlantis last week."

Jack Marburger

Statement by Director John P. Holdren on the Passing of Jack Marburger

"It is with great sadness that I note the passing of Dr. John H. Marburger, III, former Director of the White House Office of Science and Technology Policy and Science Advisor to President George W. Bush. Jack Marburger leaves a legacy of exceptional public service and substantial scientific contributions. He was the Nation's longest-serving Presidential Science Advisor, and his focus on basic research as a driver of economic growth was a common thread across Congresses and Administrations."

More Climate Change Arm Waving

New NASA Data Blow Gaping Hole In Global Warming Alarmism

"NASA satellite data from the years 2000 through 2011 show the Earth's atmosphere is allowing far more heat to be released into space than alarmist computer models have predicted, reports a new study in the peer-reviewed science journal Remote Sensing. The study indicates far less future global warming will occur than United Nations computer models have predicted, and supports prior studies indicating increases in atmospheric carbon dioxide trap far less heat than alarmists have claimed."

Senate Issues Subpoena to NASA for SLS Materials (Update)

Keith's 11:00 am EDT note: Sources are reporting that the Senate Commerce Committee has finally made good on its threat and has issued a subpoena to NASA regarding materials related to the SLS decision. Prior to this several letters and a hearing were held to prompt NASA in this regard. No luck. Congress is more or less convinced that the decision regarding SLS design/architecture has already been made and they are using the tools at their disposal to force NASA/the White House to admit that this is indeed the case. Stay tuned.

NASA Has Not Delivered All Of The Documents Requested by Congress, earlier post

Senate Threatens NASA With Subpoena For Missing Documents, earlier post

Keith's 1:00 pm EDT note: According to NASA PAO "While we share the Senators' commitment to human space exploration and implementation of the Authorization Act, we also have a commitment to be responsible stewards of taxpayer dollars. The Space Launch System is the most important -- and expensive -- decision NASA will make for the next decade, and we want to get it right so we don't repeat the mistakes of the past or get pushed into making a premature decision about our nation's deep space exploration plans."

Hope For Laid Off NASA Contractor Employees

DOE, Interior Eye Employees Jettisoned by Space Program, New York Times

"The Energy Department and the Department of the Interior are among dozens of federal agencies looking to hire some of the engineers and scientists from NASA's closing space program. NASA and the Office of Personnel Management held a job fair yesterday in Cape Canaveral, Fla., less than a week after the space shuttle Atlantis landed. All told, about 5,500 contract employees at Florida's Kennedy Space Center have lost their jobs in recent months, and NASA contractors are expected to lay off another 2,000 over the next year. For an area nicknamed the "Space Coast," the end of the space program is a blow. But federal agencies are swooping in to take advantage of a pool of employees they say have skills that are usually hard to find."

Russia Has Decided To Throw the ISS Away in 2020 (Update)

Russia Plans to Sink the International Space Station in 2020, Fox

"Russia's space agency announced Wednesday that the International Space Station -- a space base the world's scientists and billions of U.S. tax dollars helped build and maintain some 200 miles above the surface of the Earth -- will be de-orbited and allowed to sink into the Pacific Ocean in 2020, just like its Russian predecessor, Mir. "We will be forced to sink the ISS. We cannot leave it in orbit as it is a very complicated and a heavy object," Roscosmos' deputy head Vitaly Davydov said in an interview posted on the agency's website."

NASA and International Partners Discuss New Uses for Space Station

"The Multilateral Coordination Board (MCB) for the International Space Station partner agencies met Tuesday, July 26, to discuss how to use the space station as a test bed for technologies that will enable missions beyond low Earth orbit."

Keith's note: So, I guess that's it then. Russia gets to make the decision to scrap something we paid the lion's share to build and operate - after paying to keep Russia's space program aloft for a decade prior to that. Who makes all of these "deals" for the U.S. anyway? We seem to be getting the short end of the stick each and every time. Why have these MCB meetings about other uses for the ISS when Russia simply plans to scrap it anyway?

Space station sinking? Not so fast, MSNBC

"The interview from "Good Morning Russia" ("Utro Rossii") caused a stir when a Russian-language transcript turned up on the space agency's website, but don't panic: If anything, the International Space Station will be in operation well after 2020. Russia, NASA and the other partners in the 16-nation venture are looking into extending the station's lifetime to 2028 -- that is, if they can verify that its components will still be in working order until then."

Why Is NASA Caving to the Russians On ISS?, OpEd, Jim Oberg, Txchnologist

"With the retirement of the Space Shuttle Atlantis last week, American astronauts are now totally dependent on Russian vehicles for access to space. The question in front of us is how best to negotiate for fair compromises in the US-Russian space alliance. Some of NASA's recent agreements are not encouraging. The US needs to realize that it holds some high cards. True, the Russians have, in the Soyuz, the only vehicle that can carry passengers. But the destination - the International Space Station, which is more than 80 percent funded by the U.S. - provides many critical space services without which getting into orbit is pretty pointless for the Russians. Chief among them is electrical power and space-to-Earth communications, most of which comes via American equipment."

Closing NASA Data Centers

White House Announces Plans to Shut Down Hundreds of Duplicative Data Centers as Part of Campaign to Cut Waste

"To date, agencies have closed 81 data centers and will close 114 more during this calendar year for a total of 195 in 2011.This represents an increase in both planned and actual closures from the data released in April 2011. As agencies have continued to update their data center inventories, they have increased their planned closures, demonstrating the seriousness in which they are attacking waste."
