Scientists present ‘moving’ theory behind bacterial decision-making

Biochemists at North Carolina State University have answered a fundamental question of how important bacterial proteins make life-and-death decisions that allow them to function, a finding that could provide a new target for drugs to disrupt bacterial decision-making processes and related diseases.

Scripps Research scientists shed light on how DNA is unwound so that its code…

Researchers at The Scripps Research Institute have figured out how a macromolecular machine is able to unwind the long and twisted tangles of DNA within a cell’s nucleus so that genetic information can be “read” and used to direct the synthesis of proteins, which have many specific functions in the body.

Getting warmer? Prehistoric climate can help forecast future changes

New data on a prehistoric warm period allow for more accurate predictions of future climate and improved understanding of today’s warming. Past warm periods provide real data on climate change and are natural laboratories for understanding the global climate system. Scientists examined fossils from 3.3 to 3.0 million years ago, known as the mid-Pliocene warm period. Research was conducted by the Pliocene Research, Interpretation and Synoptic Mapping group, led by the US Geological Survey.

Ocean growing more acidic faster than once thought

University of Chicago scientists have documented that the ocean is growing more acidic faster than previously thought. In addition, they have found that the increasing acidity correlates with increasing levels of atmospheric carbon dioxide.The increasingly acidic water harms certain sea animals and could reduce the ocean’s ability to absorb carbon dioxide.

Developing a neighborhood watch for the Internet

Internet network performance problems are not only annoying to users — they are costly to businesses and network operators. But since the Internet has no built-in monitoring system, network problems often go unnoticed. To help fix this problem, Northwestern University researchers have developed a new way to detect and report such problems in real time. Network Early Warning System focuses only on problems that affect end-users and does so without requiring any extra network-measurement traffic.
