Diabetes research takes wing thanks to long-lived fruit fly

...year study investigating just how much control JNK seems to wield over insulin production. It's likely, for instance, that JNK counters the effects of the insulin receptor and inhibits the production of insulin, a crucial hormone that converts the food we eat into forms that the body can utilize. JNK dete...

Nanotubes used for first time to send signals to nerve cells

...e cutting edge of nanoelectronics technology -- he seems to develop something new every week, and it's really become a great interaction." ...

Knowledge of dendritic cells branches out

...han being generalized "police "within the body, it seems that DC are effectively organized as specialized squads that deal with specific problems ?just as a police force might have different departments to deal with armed robberies, homicides and fraud. These discoveries at WEHI have profoundly altered our...

No-mow grass may be coming to your yard soon

... Now, that vision of suburban bliss -- and more -- seems plausible as scientists have mapped a critical hormone signaling pathway that regulates the stature of plants. In addition to lawns that rarely require mowing, the finding could also enable the development of sturdier, more fruitful crop plants such ...

Fire ants: Their true story told by the scientist who loves them

...tly in the form of fear and loathing. The loathing seems a little unfair, since opportunistic fire ants will devour termites, ticks, weevils, mosquitoes and other major threats to Southern plants, property and people. Like a sort of subterranean family album, "The Fire Ants" details emigration, growth, st...

Light-sensitive photoswitches could restore sight to those with macular degeneration

...ctly. "I'm struck by how versatile this approach seems to be," Isacoff said, noting its applications for screening, diagnosing and treating disease. "I'm convinced that we'll come up with a therapy that will work in the clinic." ...

New angiogenesis finding may help fight cancer growth

...K-B system can work both ways: Reducing inhibition seems to increase angiogenesis. "Activating the NK-B receptor blocked angiogenesis, and blocking the receptor stimulated angiogenesis," Bresnick says. In theory, selectively stimulating angiogenesis could help treat heart attacks by restoring blood flo...

Nice guys do finish first in lizards' evolutionary race

... the animals recognize and use ?even if that trait seems on the surface to be counterproductive. "Cooperat...on then is why do some organisms cooperate when it seems like being selfish should be the best strategy?" Turns out, it's all in the genes. For two decade...

Tastes great! Study shows brain's response to pleasing -- and changing -- tastes

...er these neurons fire, the more pleasant the taste seems to become. The hardest test for a pleasure code is whether the brain signal can track the change from nasty to nice. The amazing fact is that these neurons pass that test." Aldridge notes that an analogous effect occurs in everyday human life, when...

Eat less, weigh more? Enzyme makes lean mice 'susceptible' to dietary fat

...l of Medicine and an author of the report. "CPT1c seems to allow the body to respond immediately to the level of nutrients and fat in the bloodstream." Hopeful that the discovery has broad implications for understanding the genetic underpinnings of obesity and weight management, the Hopkins investigators...

How nature tinkers with the cellular clock

...k, Professor at DTU. "This double layer of control seems so important that evolution has conserved it despite dramatic changes in the regulation of each mechanism." The new insights gained have broad implications. The principles discovered might govern also the control of other temporally regulated system...

UCSD study reveals how plants respond to elevated carbon dioxide

...rather than closed. Therefore, high carbon dioxide seems to prime the calcium sensors in the leaf. Jared Young, an assistant professor of biology at Mills College, who completed the study while he was a graduate student working with Schroeder at UCSD, likened this priming to removing ear plugs from someone...

Beauty and the brain

...hose images that were closest to prototype. "It seems you don't need to postulate an unconscious calculator of mate value or any other 'programmed-brain' argument to explain why prototypical images are more attractive," Winkielman said. "The mental mechanism appears to be extremely simple: facilitate pr...

Save the whales? Sure, but how many?

Resistant bacteria increasing source of muscle infection

However, she said, they have not yet determined whether the problem is this specific gene or another that is close to it. Others who participated i...

MIT finds most complex protein knot ever seen

...een the knot and the protein's function. This also seems to suggest that the knot has been "highly preserved throughout evolution," Virnau said. Until now, scientists have not paid much attention to knots in proteins, but the MIT researchers hope their work will ignite further interest in the subject. "W...

New path from estrogen to survival in breast cancer cells described

...d to be involved in suppressing cancer development seems important to us," Yeh said. "The reason people live longer is that they don't develop cancer as readily." Players in this newly defined pathway are: BCA3, which had no known function. NEDD8, a protein that can bind to other proteins and alter...

Far more than a meteor killed dinos

The story that seems to be taking shape is that Chicxulub, though violent, actually conspired with the prolonged and gigantic eruptions of the Deccan Flood Basalts in India, as well as with climate change, to nudge species towards the brink. They were then shoved over wi...
