Wood stoves -- a viable home heat source?
MADISON, WI -- JULY 14, 2009 -- The stress of rising natural gas prices is leading many consumers to rethink how they heat
their homes. For some this means moving towards modern alternative energy options, while others have been turning to a more traditional method for a solution to these rising ...
Targeting helpers of heat shock proteins could help treat cancer, cardiovascular disease

Genome of a heat and drought resistant cereal plant analyzed
2009-01-30. The global climate is changing, and this change is already impacting food supply and security. People living in regions already affected by aridity need plants that can thrive / grow under dry conditions.
One example is sorghum: Also known as milo, durra, or broomcorn, sorghum is a ...
The continents as a heat blanket
Drifting of the large tectonic plates and the superimposed continents is not only powered by the heat-driven convection processes in the Earth's mantle, but rather retroacts on this internal driving processes. In doing so, the continents function as a thermal blanket, which leads to an accumulati...

Wasps and bumble bees heat up, fly faster with protein-rich food
Good pollen makes bees hot, biologists at UC San Diego have found. Wasps warm up too when they find protein-rich meat, a separate experiment has shown.
In both cases warmer flight muscles likely speed the insects' trips home, allowing them to quickly exploit a valuable resource before competito...
Too hot to handle! Scientists identify heat sensing regulator
Neuroscientists at Johns Hopkins are a step closer to understanding pain sensitivity - specifically why its variable instead of constant - having identified a gene that regulates a heat-activated molecular sensor.

Moss genome shows how plants invaded the land and learned to survive heat and drought
Berkeley -- Some 400 million years ago, on a lifeless lakeshore lapped by waves, floating algae learned to survive in the open air and launched an invasion that transformed the Earth into a green paradise.
The secrets of these first steps onto land are now being revealed thanks to the sequencin...

Molecular thermometers on skin cells detect heat and camphor
The human brain is like a general in a bunker.
