In mice, drug protects against diabetes and atherosclerosis

...he animal results as a long-sought success after a decade of intense efforts to achieve with a chemical what has been observed in mice and humans carrying the gene variant. The lipid chaperone protein aP2 acts as a signal in cells, setting off a chain of inflammatory and metabolic responses to consumptio...

Salty oceans provide early warning for climate change

...ver very short time-scales, usually in less than a decade or two. Ocean water can’t possibly travel this fast (it takes nearly a century for a parcel of water to move from the South Atlantic to the North Atlantic). Instead the scientists think that energy is transferred through the ocean along a deep pressu...

Smoking rate has plummeted in New York City

...ww.cdc.gov/mmwr/ . Beginning in 2002, and after a decade with no progress, New York City increased the tobacco tax, eliminated smoking in virtually all workplaces, and launched hard-hitting anti-tobacco ads. By all indications, the interventions have made a difference. “Hard-hitting ads work,” said Health ...

How plague-causing bacteria disarm host defense

...ly into the host cell's cytoplasm. "More than a decade after its discovery, our understanding of YpkA is still incomplete," Navarro said. "But Yersinia has maintained YpkA over millions of years, so it must be doing something important." The researchers speculate that YpkA plays an important role in di...

Lessons from the orangutans: Upright walking may have begun in the trees

Arctic ice retreating more quickly than computer models project

Puzzling plankton yield secrets to role in evolution/global photosynthesis

...me an intense field of investigation over the last decade as these microalgae, although representing a minor component of the plankton, nevertheless play major roles in oceanic biomass production. "With even more picoplankton genomes in the sequencing queue at DOE JGI, we’re positioned to secure a better...

'Personality-gene' makes songbirds curious

...y differences among humans. Research from the last decade suggested a promising link between the Drd4-gene and the trait curiosity (novelty-seeking). Scientists from the Max Planck Institute for Ornithology in Seewiesen, together with a former lab member who is now at the Cawthron Institute in Nelson (New Z...

Double the death rate from cirrhosis for 'blue collar' men

...ercent of people who drink heavily for more than a decade ?three to four drinks a day for men and two to three drinks a day for women. "Lower socio-economic groups appear to have increased their harmful alcohol consumption relative to middle and higher SES groups. This may be due to the increased afford...

Study of protein folds offers insight into metabolic evolution

...ues of phylogenetic analysis developed in the past decade to plot the evolution of genes and organisms but which have never before been used to work out the evolutionary history of protein architecture across biological networks. "We are interested in how structure evolves, not how organisms evolve," sai...

Lighting up life: Cold Spring Harbor Protocols presents tips for creating glowing plants

Just over a decade ago, biologists isolated a unique protein from jellyfish that could be inserted into other organisms—from E. coli to pigs—and cause them to radiate a brilliant green color. This green fluorescent protein (GFP) has allowed biologists to make many ne...

Researchers learn what sparks plant growth

...rs. The new discovery, which builds on more than a decade of painstaking surveillance of cellular communication between different types of plant tissues, shows clearly for the first time how plants "decide" to grow. The research, conducted by Sigal Savaldi-Goldstein and Howard Hughes Medical Institute inve...

McBride shows DNA detective work with paper-eating bacteria that 'glide'

...at propel the cells. It has been a long process. A decade ago, his lab had found one protein involved. He now knows of 24, and he doesn't expect to find many more. Until recently, McBride was not able to image the bacteria closely enough to see the structures involved in movement. Instead, he bonded latex...

Robotic therapy helps restore hand use after stroke

New sucker-footed bat discovered in Madagascar

...t been intensively studied, Goodman said. "Until a decade ago, these animals remained largely understudied. On the basis of recent surveys and taxonomic research, about one-third of the island's bat species were unknown to scientists until a few years ago, and the majority of these are new to science." ...

New findings blow a decade of assumptions out of the water

... enough iron, the conventional wisdom for the past decade dictated that the Atlantic Ocean would be the prime site for fixing nitrogen. That's because compared to the other low-latitude oceans, the Atlantic is peppered with iron-laden dust blowing off the African continent. Winds can't carry such dust al...

Warming oceans threaten Antarctic glaciers

...el rise of 0.35 millimetres per year over the past decade ?representing about 12 per cent of the current global trend. However, despite recent attention that has focused on the importance of the Greenland ice sheet, the research shows that its glaciers are changing too erratically to establish a trend wi...

Procedure predicts embryos most likely to result in pregnancy

...hese statistics remained unchanged within the last decade suggesting that an improvement is needed over the current methodology used for embryo evaluation. The new procedure will be presented in an abstract at the Society for Gynecologic Investigation Conference in Reno, Nevada on March 16. Emre Seli, M...

Stem cell transplants explored at Stanford as a possible treatment for hearing loss

...aking this dream a reality. It may take another decade or so, but if anyone can do it, he's the guy to place your bets on. "Everyone asks, 'How long before we do this?'" said Heller, PhD, associate professor of otolaryngology, whose accent still bears the trace of his native Germany. "I tell them t...

Gene hunters close in on Lou Gehrig’s disease

...t only 5 percent of all cases -- were discovered a decade ago, but no genetic roots have previously been found for sporadic ALS, which occurs in people without a family history of the disease. In the Johns Hopkins study, described in the online version of Lancet Neurology this month, Traynor and his team...
