Scientists found pigment cells inside dinosaur feathers, now we know their actual colors
Dinosaurs are often depicted in dull shades of brown and gray, but fossil evidence is changing that image. Scientists have discovered microscopic pigment structures called melanosomes preserved in ...
The work challenges the assumption that all life descended from one free-living cell. Instead, it suggests that two microbial lineages, the bacteria and archaea, evolved independently from a ...
Scientists say they have built a cell from scratch for the first time that can feed, grow and replicate like a natural cell. This breakthrough in synthetic biology could usher in an era of ...
In the oceans and on land, scientists are discovering rare, transitional organisms that bridge the gap between Earth’s simplest cells and today’s complex ones. By Carl Zimmer A flurry of new studies ...
Let’s say it’s 2036, and scientists are working on a new class of drugs. These medications are mirror-image versions of the molecules your body uses to fight disease. Their big advantage is that ...
John M. Archibald is in the Department of Biochemistry and Molecular Biology, Dalhousie University, Halifax, Nova Scotia B3H 4H7, Canada, and also at the Institute for Comparative Genomics, Dalhousie ...
CINCINNATI (WKRC) - Dodo birds could return from extinction in just "five to seven years," according to a company that specializes in reviving extinct animals. The dodo bird went extinct less than 80 ...
The first life on Earth formed four billion years ago, as microbes living in pools and seas: what if the same thing happened on Mars? If it did, how would we prove it? Scientists hoping to identify ...
