Antarctic ice shelf retreats happened before

...s ago the ice shelf retreated, allowing the sea to flood into the lake. The ice shelf didn't reform until 1500 years later, and has been present ever since. The findings are particularly relevant for other studies on the West Antarctic Ice Sheet where scientists have found that a relatively warm current, ...

...t to its number -- and its number only -- from the flood of electronic signals on the air at any given time. When the transducer captures the signal, it is processed with advanced signal processing algorithms, specially developed by Marmarelis' group, to form the multi-band images.

Beneficial Beetles Battle Pesky Saltcedar

...low their banks, saltcedar bushes can trap natural flood debris, blocking waterflow and causing new, erosive channels to form. These channels sometimes undercut farm roads and fields, causing them to collapse. What's more, river rafters or thirsty wildlife and livestock often can't get through dense thick...

Molecular cabal contributes to stroke damage

...ed sensitivity causes the ASIC channel to open and flood the neuron with lethal doses of calcium. Importantly, the researchers found in cultures of neurons that drugs that inhibited NMDAR or CaMKII prevented the ischemia-induced enhancement of ASIC sensitivity, as well as neuronal death.
