Scientists have, for the first time, mapped a young gene’s short, dramatic evolutionary journey to becoming essential, or indispensable. The researchers detail one gene’s rapid switch to a new and essential function in the fruit fly, challenging the long-held belief that only ancient genes are important.
A new set of long-term climate records based on cave stalagmites collected from tropical Borneo shows that the western tropical Pacific responded very differently than other regions of the globe to abrupt climate change events.
Bioengineers have developed a computational model of 1,366 genes in E. coli that includes 3D protein structures and has enabled them to compute the temperature sensitivity of ...
Architect genes are responsible for organizing structures of the body during embryonic development. Some of them, namely the Hox genes, are involved in the formation of forelimbs. They are activated in two successive waves, enabling the formation of the arm, then the hand. Scientists are uncovering the workings of this complex process.
A 2012 law that loosened conflict-of-interest restrictions for FDA advisory panels could weaken the agency's review system and could allow more drugs with safety problems to gain market approval, says a new analysis.
Colonies of gannets maintain vast exclusive fishing ranges despite doing nothing to defend their territory from rival colonies, scientists have discovered.
A property known as "entanglement" is a fundamental characteristic of quantum mechanics. Physicists and mathematicians have now shown how different forms of this phenomenon can be efficiently and systematically classified into categories. The method should help to fully exploit the potential of novel quantum technologies.
By activating a brain circuit that controls compulsive behavior, neuroscientists have shown that they can block a compulsive behavior in mice -- a result that could help researchers develop new treatments for diseases such as obsessive-compulsive disorder and Tourette's syndrome.
Spindle-shaped inclusions in three-billion-year-old rocks are microfossils of plankton that probably inhabited the oceans around the globe during that time, according to scientists.
