All the eggs in one basket

...ndscape of coral reefs. The scientists say more protection is needed for the sea turtle nesting sites. "Protecting more nesting beaches is not a politically or socially simple endeavor, but it is the only way to avoid the risk of putting all turtle eggs in a very few baskets." Conservation implications...

Gorilla susceptibility to Ebola virus: the cost of sociality

Experimental vaccine protects lab animals against several strains of H5N1

...ly strain labeled A/Vietnam/1203/04. Cross-strain protection is exactly what one would need, as it would protect against newly emerging variants until a strain-specific vaccine can be developed. The reverse genetics method used by the St. Jude investigators would allow rapid vaccine preparation, which is cruci...

Smell of success for nanobiosensors

...e but also in agriculture, industry, environmental protection or security. "The potential uses of smell technology are endless," notes Josep Samitier, the coordinator of the SPOT-NOSED project that developed nanobiosensors to mimic the way human and animal noses respond to different odours. This new nose bio...

Plant protection from cold decoded

...the genetic cascade that provides the plant's cold protection proteins, according to the paper. The interaction worked both in the test tube and in the live plant. "The better we understand this molecular mechanism, the better we can control the process of increasing the plant's freezing tolerance without caus...

Promising cell protein may play role in infection and dry eye

...the inhibition of microbial proteinases and in the protection against stromal degradation. High levels of the PAI-2 protein are associated with a good prognosis in breast cancer, small cell lung, ovarian cancer, and inhibition of metastasis. PAI-2 also plays a role in inflammation on the surface of the eye. I...

Scientists identify protein with a crucial role in cell death

...xygen into energy, they have apparently lost their protection against apoptosis, and so the cells die off more quickly. Therefore, PARL plays a crucial role in the cells' dying off process and, consequently, probably also in the origin of diseases of ageing, like Parkinson's disease. ...

"Our model, which is confirmed by field data, shows that torpor patterns generally seen in some hibernating animals may be an evolutionary adaptation to help protect them from bacteria that grow well in low te...

Magnetism and mimicry of nature hold hope for better medicine, environmental safety

Critical advances in medicine and environmental protection promise to emerge from a new method for biochemical analysis of fluids developed by an international science team led in part by Arizona State University researchers. Called "digital magnetofluidics," it promises more rapid, more accurate and less ...
