New research shows sharks use their noses and bodies to locate smells

...the odor alone (the odor-oozing nozzle). Plume and target preference and search time were not significantly affected by light condition. In the light, lesioning the lateral line increased search time, but did not affect success rate or plume preference. However, lesioned animals no longer discriminated ...

Salk scientists hammer out a pathway that promotes muscle cell survival in mice

...now firmly in place, expression of muscle-specific target genes was also reduced. Conversely, when the researchers boosted SIK1 levels or inhibited HDAC activity with a drug, muscle cell health was restored in mice genetically engineered to lack CREB and suffering from muscle weakness as a result.

'Personality-gene' makes songbirds curious

...ard to control experimentally. Birds are an easier target for research and indeed, they also have different personalities. An international team of researchers have now found evidence for the existence of a "curiosity-gene" in a songbird, the great tit (Parus major). The gene (Drd4) carries the building i...

Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness

...ay, as well as many hormone and neurotransmitters, target a specific family of cell surface receptors known as G-protein coupled receptors. The researchers believe that the presence or absence of nitric oxide or SNOs determines whether these receptors continue to function properly. This action is controlled...

Alien plants attack using 'resource conservation' as weapon, researchers say

... what the characteristics of the invasives are and target your strategy to those characteristics," he said. Funk pointed to recent experiments that tried to eliminate invaders by deliberately reducing available resources-for example, by mixing sugar into the soil to lock up nutrients or by blocking sunli...

Targeting sugar on blood vessels may inhibit cancer growth

...ng cancers. "If novel drugs can be developed to target tumor heparan sulfate, we might be able to make a leap in cancer-fighting therapies, because several molecules critical to tumor endothelial growth also bind to heparan sulfate," Fuster said. "Altering this binding would allow for suppression of a b...
