Rare Chinese Mountain Cat
Rare Chinese Cat Captured on Film
Triggered by body heat, a remote camera recently captured this image of the elusive Chinese mountain cat at about 12,300 feet (3,750 meters) on the edge of the Tibetan Plateau in China’s Sichuan Province. A total of eight images of the feline represent the first time the mountain cat has been photographed in the wild, said Jim Sanderson, a cat specialist with the Wildlife Conservation Network who led the team that snapped the rare shots. A paper about the cat will appear in an upcoming issue of the journal Science.

I am biased by my love of cats but I hope this helps conservation efforts.

Finding Protease Inhibitors
Can’t Cut This by Kathleen M. Wong, ScienceMatters@Berkeley:
When a malaria parasite lands in your blood, one of the first things it does is whip out its scissors. As fast as it can, this protozoan snips the hemoglobin in red blood cells to get the nutrients it needs to survive. Of course, the microbe behind this deadly disease doesn’t actually deploy stainless-steel blades. Instead, it uses an array of biochemical scissors known as proteases.
Proteases are enzymes that snip proteins. They recognize certain strings of amino acids on a substrate protein, bind to this area, then break a nearby chemical bond. Proteases can destroy proteins by snipping them in half, as in malaria. They can also activate proteins by lopping off atoms covering a reactive site.
This versatility has made proteases critical to all manner of organisms, from viruses to plants to humans. Over the past 10 years, protease inhibitor drugs have become indispensable in the fight against AIDS, cardiovascular disease and diabetes. But finding protease inhibitors is no picnic. Humans manufacture tens of thousands of proteins; figuring out which of these a protease targets is extremely challenging and time consuming.

Internships Pair Students with Executives
Preparing to Lead: Internships pair students with executives
Mechanical and aerospace engineering major Zhen Xia is accustomed to solving problems that have cut-and-dried solutions, but an internship at IBM this past summer taught him how to approach problems that don’t have one right answer.
As part of a new internship program, Xia spent three months working with senior marketing executives at the IBM corporate offices in Somers, N.Y. From analyzing the brand’s image to establishing a business case for a new product launch, he found himself in the midst of the complicated intricacies of the business world.
“Unlike technical problem-solving where everything is black and white, problem-solving in business deals heavily with people and customers who have many different viewpoints,” Xia said. “In business, there are various shades of gray, which make things exciting and interesting.”

Publishers Continue to Fight Open Access to Science
Publishers prepare for war over open access
On one side are the advocates of open-access journals – publications that make academic papers freely available and recoup costs by charging authors to publish. The model seems increasingly successful. New open-access journals are springing up weekly and could gain support if the US acts on plans make all its publicly funded health research freely available via a government archive.
Lined up against them are the academic publishers. The idea of open-access journals is frightening for an industry whose profits are based on subscription charges.
…
Dezenhall’s strategy includes linking open access with government censorship and junk science – ideas that to me seem quite bizarre and misleading. Last month, however, the AAP launched a lobby group called the Partnership for Research Integrity in Science & Medicine (PRISM), which uses many of the arguments that Dezenhall suggested.
It is sad to see journals that were founded to promote science so flawed in their thinking today. As I said last month in Science Journal Publishers Stay Stupid: “It is time for the scientific community to give up on these journals and start looking to move to work with new organizations that will encourage scientific communication and advancement (PLoS – arXiv.org – Open Access Engineering Journals) and leave those that seek to keep outdated practices to go out of business.” Organizations can’t ignore principles when choosing tactics. Tactics that might be ok in other situations, should not be acceptable to scientists publishing scientific information. When journals move to harm science to preserve their outdated business practices they deserve to lose the respect of scientists.

How Does That Happen? Science Provides the Answer
In January I dropped some bricks into my pond, which is a metre deep. In March the pond froze over and an image of the bricks appeared like a hologram in the ice (see Photo – follow link above). What caused this?
…
The rough surface of the bricks, particularly around the edges and corners, provides nucleation sites for dissolved gases. Gas molecules collect preferentially around the edges of the bricks, eventually producing bubbles. As these reach a critical size they break away and float straight upwards in the still water. Because there is a layer of ice on the surface, the bubbles become trapped and frozen into it. As the ice layer thickens and bubbles continue to rise from the brick, the 3D shape develops. The rate of bubbling was probably very slow, as was the rate of freezing, so the very detailed effect was able to form.

CMU Professor Gives His Last Lesson on Life
CMU professor gives his last lesson on life by Mark Roth:
“If I don’t seem as depressed or morose as I should be, sorry to disappoint you,” said Dr. Pausch, a 46-year-old computer science professor who has incurable pancreatic cancer. It’s not that he’s in denial about the fact that he only has months to live, he told the 400 listeners packed into McConomy Auditorium on the campus, and the hundreds more listening to a live Web cast.
…
In his 10 years at Carnegie Mellon, Dr. Pausch helped found the Entertainment Technology Center, which one video game executive yesterday called the premier institution in the world for training students in video game and other interactive technology. He also established an annual virtual reality contest that has become a campuswide sensation, and helped start the Alice program, an animation-based curriculum for teaching high school and college students how to have fun while learning computer programming.

It was the virtual reality work, in which participants wear a headset that puts them in an artificial digital environment, that earned him and his Carnegie Mellon students a chance to go on the U.S. Air Force plane known as the “vomit comet,” which creates moments of weightlessness, and which the students promised to model with VR technology.
…
“A recent CT scan showed that there are 10 tumors in my liver, and my spleen is also peppered with small tumors. The doctors say that it is one of the most aggressive recurrences they have ever seen.”
…
“I find that I am completely positive,” he wrote. “The only times I cry are when I think about the kids — and it’s not so much the ‘Gee, I’ll miss seeing their first bicycle ride’ type of stuff as it is a sense of unfulfilled duty — that I will not be there to help raise them, and that I have left a very heavy burden for my wife.”
An inspirational story. For me personally, it reminds me of my father: Bill Hunter who honestly believed, as he was stricken with cancer, he was luckier than most people that have ever lived. He was able to do many things that no-one, not even Kings, could have dreamed of even a hundred years before. I can’t manage such an outlook most of the time, but I do try and keep that spirit alive in me at times. William G. Hunter: An Innovator and Catalyst for Quality Improvement by George Box.

Scores Ill in Peru after Meteor Strike
Scores ill in Peru ‘meteor crash’
Some 600 people in Peru have required treatment after an object from space – said to be a meteorite – plummeted to Earth in a remote area, officials say. They say the object left a deep crater after crashing down over the weekend near the town of Carancas in the Andes.
People who have visited scene have been complaining of headaches, vomiting and nausea after inhaling gases. A team of scientists is on its way to the site to collect samples and verify whether it was indeed a meteorite.
…
The object then hit the ground, leaving a 30m (98ft) wide and 6m (20ft) deep crater. The crater spewed what officials described as fetid, noxious gases. The gases are believed to have affected the health of about 600 people who visited the site.
