Healthy coral reefs of Madagascar resisting damage from climate change
... other Indian Ocean reefs. The researchers believe cool water currents from adjacent deep ocean areas offset the warming effects of climate change. "The resiliency and health of the coral reefs with their biodiversity and endemism makes the reefs of Madagascar a high conservation priority," said Gerald R....Scientists to employ Arctic ice and polar bears to protect diversity of world's crops
...perts believe the deep permafrost will be reliably cool for at least the next 100 years.

... RNA was reduced by approximately 80 percent. "The cool thing is that here, an antiviral is encoded by a host function and not by the virus - so it cannot change," said Sarnow. In other words, because the virus needs miR-122 to replicate, there is no way the virus could develop resistance to a strategy th...Respiration rate of sorghum may indicate cold tolerance

...led why they are models of lethal efficiency. "The cool thing is that the neurotoxin receptor is on actively recycling synaptic vesicles, so the toxin targets only active neurons and shuts them down," he said. "There is no wasted toxin, because once a nerve terminal is shut down, it doesn't take up any mo...Early land animals could walk and run like mammals, new study finds
