Protective kelp forests found near many early coastal archaeological sites
If humans migrated from Asia to the Americas along Pacific Rim coastlines near the end of the Pleistocene era, kelp forests may have aided their journey, according to research presented today at the American Association for the Advancement of Science (AAAS) annual meeting.
Until recently, the "coastal migration theory" was not accorded much importance by most scholars. However, new discoveries have moved it to the forefront of debate on the origins of the First Americans. It is now known that seafaring peoples living in the Ryuku Islands and Japan near the height of the last glacial period (about 35,000 to 15,000 years ago) adapted to cold waters comparable to those found today in the Gulf of Alaska. From Japan, they may have migrated northward through the Kurile Islands, to the southern coast of Beringia (ancient land bridge between what is now Siberia and Alaska), and into the Americas.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
