Noted paleoanthropologist Richard Leakey says scientific discoveries may soon make the debate over evolution a part of history. The Kenyan-born scientist serves as a professor at Stony Brook University on New York’s Long Island and recently spent a month in New York raising funds for his Turkana Basin Institute. Leakey says the institute welcomes scientists,…
The great thinkers of the Age of Reason and the Enlightenment were scientists. Not only did many of them contribute to mathematics, physics, and physiology, but all of them were avid theorists in the sciences of human nature. They were cognitive neuroscientists, who tried to explain thought and emotion in terms of physical mechanisms of…
Polar and brown bears diverged between 4 million and 5 million years ago, but they continued to interbreed when the climate warmed. Now, there is evidence that it is happening again.
Fertilizers used in growing feed crops for cattle produce the most potent of the greenhouse gases causing climate change
Researchers at Harvard’s Wyss Institute have coaxed single strands of DNA to fit together like Lego bricks and form scores of complex three-dimensional shapes, including a teeny-tiny space shuttle. The technique, described in the journal Science, adds a new dimension to molecular construction and should help open the way for nanoscale medical and electronic devices….
A basic tenet underpinning scientists’ understanding of extinction is that more abundant species persist longer than their less abundant counterparts, but a new University of Georgia study reveals a much more complex relationship. A team of scientists analyzed more than 46,000 fossils from 52 sites and found that greater numbers did indeed help clam-like brachiopods…
