Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily

... findings definitely will change how theoreticians think about virus-cell interactions. This same phenomenon could provide a general way that viruses use to infect cells, so it will be exciting to look at other viral systems with our experimental method,” she said. Many different viruses could enter cells...

Art and music for the birds

...ng. “My interest with the piece was to get us to think about the impact we have on the other species around us,” she adds. The bird listening stations are part of the exhibition “Inside/Outside: Habitat” on view at the Abington Arts Center’s Sculpture Park in Jenkintown, Pa., through Wednesday, Nov. 21...

Brain inflammation may be friend, not foe, for Alzheimer's patients

...mmation is not simply the bad guy that many people think it is.” The work could have ramifications for the development of a vaccine or other strategy to protect against or fight off Alzheimer’s. Work on an Alzheimer’s vaccine has at times been promising, reducing the number of plaques in the brains of a...

Studies to find better ways to preserve human eggs, ovarian tissue under way

... destroy dynamic reproductive tissue. “I don’t think when you are faced with the reality that you may die, your fertility is the most important thing you are thinking or talking about, but there are a lot of women interested in talking about it,” says Dr. Emmi. She hopes her work with Dr. Ying C. Song,...

Ancient DNA traces the woolly mammoth's disappearance

...the researchers said, because scientists tended to think that the major environmental changes happened about fifteen to twenty-five thousand years ago, when the glaciers reached their fullest extent. The findings also offered early human hunters a potential alibi; they didn’t come on the scene in large num...

New study finds genetically engineered crops could play a role in sustainable agriculture

...ied crops. The results are significant for how we think about technology and the future of sustainable agriculture,” said Peter Kareiva, chief scientist of The Nature Conservancy. According to lead author, Michele Marvier, of Santa Clara University, “We can now answer the question: Do Bt crops have ef...

Salty oceans provide early warning for climate change

...tic to the North Atlantic). Instead the scientists think that energy is transferred through the ocean along a deep pressure wave. “The surge of salt generates a pressure gradient in the ocean that sends energy to the north without water actually being transported,” explains Zahn. Regardless of whether ...

Researchers shed light on shrinking of chromosomes

...arried out the experiments in Ellenberg’s lab, “we think that the ‘super condensation’ at later stages helps to disentangle such chromosomes and acts as a back-up mechanism to rescue separation defects.” The EMBL researchers found that an enzyme called Aurora kinase is crucially involved in this process....

Nurtured chimps rake it in

Finally, a research team that included Verbalis recently reported in the American Journal of Medicine that release from muscles of a cytokine known as interleukin-6 (Il-6) is also ...

Turn-ons and turn-offs for neurons

Ants show us how to make super-highways

Professor Franks said: "I think every road user who has ever inwardly cursed as their vehicle bounced across a pothole – jarring every bone in their body – will identify with this story. When it comes to rapid road repairs, the ants have their own do-it-yourself highways agency." ...

Protein enables discovery of quantum effect in photosynthesis

Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

... University of Bath. "People studying diseases think that the kind of gene-for-gene interaction between pathogen and host that we have found is quite common, but actually rather few are known, which is why this research is so interesting. "The immune systems of all animals, even relatively simple on...
