Controversy Continues Over Whether Hot Water Freezes Faster Than Cold
5hIt sounds like one of the easiest experiments possible: Take two cups of water, one hot, one cold. Place both in a freezer and note which one freezes first.

Life in the Earth's interior is as productive as in some ocean waters
6hTerrestrial and marine habitats have been considered the ecosystems with the highest primary production on Earth by far. Microscopic algae in the upper layers of the oceans and plants on land bind atmospheric carbon (CO2) and produce plant material driven by photosynthesis. Since sunlight does not penetrate into the subsurface, hardly any such primary production is to be expected.

Artificial intelligence could spot baby chickens in distress
21hChickens make more sounds than most of us realize. They cluck when content, squawk when frightened, and sing "buk, buk, ba-gawk" when laying an egg. Their chicks vocalize too, and they can vary that simple sound to signal pleasure or distress. Now, scientists have developed an artificial intelligence (AI) program that automatically identifies these SOS calls, an advance that could help farmers sa
