For many insects, winter survival is in the genes
...se a number of specialized proteins to survive the chilly
months. These so-called "heat-shock proteins" ensure that the insects will be back to bug us come spring. A study of flesh flies and a handful of other insects suggests that they have an arsenal of protective heat-shock proteins that are turned o...
New findings blow a decade of assumptions out of the water
...en, letting in cold air. The house could get quite chilly
before the draft reaches the thermostat and the furnace turns on. But if the thermostat is in the same room as the window, the furnace will turn on and even out the temperature much faster. In his research Deutsch used a novel analysis of surface nu...
Icelandic volcano caused historic famine in Egypt, says Rutgers-based team
...In the northern hemisphere, the summer of 1783 was chilly
the coldest in at least 500 years in some locations, according to tree ring data. Sulfate aerosols in the atmosphere kept the warmth of the sun from the Earth's surface. While the computer linked these reduced northern hemisphere temperatures to ...
Seals protect brain, conserve oxygen by turning off shivering response on icy dives

...and other marine mammals are disappearing from the chilly
waters off the Alaskan coast. The population decline, which has become a focus of research in the past 10-15 years, is potentially due to a variety of factors, Polasek said, including: changes in availability of prey warming ocean waters pollutio...
