Oceans turning to acid from rise in CO2

...y. See http://www.royalsoc.ac.uk/ Many scientists view the world's oceans as an important sink for capturing the human-induced greenhouse gas CO2 and slowing global warming. Marine plants soak up CO2 as they breathe it in and convert it to food during photosynthesis. Organisms also use it to make their s...

Tiny roundworm's telomeres help scientists to tease apart different types of aging

...ll Biology Laboratory, provide a much more nuanced view of telomeres and the process of cellular and organismal aging. "Some long-lived species like humans have telomeres that are much shorter than the telomeres in species like mice, which live only a few years. Nobody yet knows why. But now we have conc...

New technology shows our ancestors ate…everything!

...physical anthropologists have had a somewhat naive view on diet, in part due to the limitations of time-consuming, subjective approaches to analyzing teeth," said Teaford. "So it's a huge step to have a reliable technology that detects subtler diet variations." A team of scientists from the University of...

DNA traces evolution of extinct sabertooths and the American cheetah-like cat

...esearchers has obtained data that help clarify our view of the evolutionary relationships shared by the large predatory cats that once roamed the prehistoric New World. The work is reported in the August 9 issue of Current Biology by Ross Barnett of the University of Oxford and a team of researchers from...

Rutgers to lead $52.7 million protein research program

...e hope that the PSI will allow us to develop a new view of the relationships between protein sequence, protein structure and protein function that will ultimately make the three-dimensional structures and functions of most proteins predictable from the protein sequence," said Barry Honig, professor of bio...

Brain networks change according to cognitive task

... By the end of the 20th century, a "connectionist" view stressing the importance of interconnected networks became the consensus. The research presented in the Journal of Neuroscience effectively sets the stage for further development in our understanding of neuroscience. In their article, the Northweste...

MSKCC researchers uncover structure of key protein complex in cells

...biquitin, said the latest work "has given us a new view and a detailed understanding" of the process of sumoylation and should lead to a better grasp of SUMO and ubiquitin. "Identifying the additional roles of sumoylation may well provide us with new targets to inhibit the protein and therapeutic agents f...

Drugs from the deep blue

...quires skills in all areas of chemistry and a wide view of allied disciplines, Molinski said. "It's like a crossword puzzle where you have to find the clues," he said. "Natural products engage your intellectual curiosity with a sense of wonder that comes from standing at the shores of new worlds." ...

Lactose intolerance linked to ancestral environment

...athogens and other toxins." A Darwinian medicinal view complements traditional medicine, Sherman said, because if researchers can better understand why a symptom occurs, such as a fever, runny nose or allergy, they can better evaluate whether it is best to eliminate or tolerate it. ...

India's smoking gun: Dino-killing eruptions

...nction that ended the reign of the dinosaurs. "Our view is that impact added to the stress already generated by an ongoing massive eruption, enhancing significantly the extent of the extinction, which would however have taken place even if the impact had not occurred." Wiped out in the K-T mass extinctio...

FDA: 'Highly Unlikely' Green Tea Lowers Cancer Risk

The robot improves the view that the surgeon has, and its instruments have more flexibility to perform the delicate nerve sparing and sewing parts of the procedure," he said. Patients, in turn, recover quickly and are able to resume their normal life within days of major surge...

Single gene is genetic switch for fly sexual behavior

...ere is "something of a debate going on between the view that single genes can have profound effects on behavior, versus the more holistic view that behavior is so complex that we can never learn anything meaningful about a behavior by studying...

Computer modeling reveals hidden conversations within cells

...k, which shuts them down rapidly. "The prevailing view has been that proteins are either on or off like a light switch, but that didn't explain how activating the same proteins with different chemicals could have opposing effects on cells," explained Hoffmann. "Our model shows that, analogous to how a t...

New understanding of jet lag

...s. "This new finding adds support to the emerging view that the central timekeeper, the SCN, is more complex than previously thought, and in fact adjusts to light cycle shifts at a different rate within its own structure," Block said. "Most importantly, the new research identifies the mechanism that coup...

Virtual animal shelters ?How the Internet is transforming the experience of pet adoptions

...one," Garcia says. "Because potential adopters can view photos and descriptions of dogs over the Internet, they can pre-screen them and decide which specific dogs they want to visit in person. The Internet thus has had a profound effect on the process of dog adoption." Garcia finds that the descriptive o...

Scientists discover gene that controls speed of tuberculosis development

...Academy of Science (PNAS) this week provides a new view of the mechanisms underlying the development of tuberculosis and may contribute to public health efforts aimed at containing the disease. "About one-third of the world's population is infected by Mycobacterium tuberculosis--the bacteria responsible ...

UCSD study clarifies insulin's role in blocking release of energy in patients with type II diabetes

...fluorescent tags so that scientists can physically view the protein under a microscope and watch how the live cell activates PKA in real time. The PKA is normally activated inside the adipocyte cell, the major site of energy storage in the body where many aspects of metabolism are controlled. There, energ...

Research suggests fitness of Florida panthers improved by limited breeding with Texas animals

In view of the paper's importance for management decisions, its authors and the journal's editors agreed to make the full text available now, said Stuart Pimm of Duke University, the principal author. "There are hugely difficult controversies that I'm certa...
