The main focus of enzymology lies on enzymes themselves, whereas the role of water motions in mediating the biological reaction is often left aside owing to the complex molecular behavior. Researchers have revised the classical enzymatic steady state theory by including long-lasting protein-water coupled motions into models of functional catalysis.
Scientists report a new method for establishing whether chemical compounds are safe for human use without in-vivo testing, based on so-called 'molecular initiating events' at the boundary between chemistry and biology.
As genome sequencing has gotten faster and cheaper, the pace of whole-genome sequencing has accelerated, dramatically increasing the number of genomes deposited in public archives. Although these genomes are a valuable resource, problems can arise when researchers misapply computational methods to assemble them, or accidentally introduce unnoticed contaminations during sequencing.
Until now, in cases of bone fracture, doctors have used implants made of steel and titanium, which have to be removed after healing. To spare patients burdensome interventions, researchers are working on a bone substitute that completely degrades in the body. Towards this end, material combinations of metal and ceramic are being used.
Researchers have constructed the first gene network that can be controlled by our thoughts. The inspiration for this development was a game that picks up brainwaves in order to guide a ball through an obstacle course.
By transforming human scar cells into blood vessel cells, scientists may have discovered a new way to repair damaged tissue. The method appeared to improve blood flow, oxygenation, and nutrition to areas in need.
Researchers have used synthetic biology to produce an inexpensive and reliable microbial-based alternative to the world's most effective anti-malaria drug, and to develop clean, green and sustainable alternatives to gasoline, diesel and jet fuels. In the future, synthetic biology could also be used to make manned space missions more practical.
Researchers have successfully replicated a direct brain-to-brain connection between pairs of people as part of a scientific study following the team's initial demonstration a year ago. In the newly published study, which involved six people, researchers were able to transmit the signals from one person's brain over the Internet and use these signals to control the hand motions of another person within a split second of sending that signal.
An international team of bioengineers has boosted the ability of bacteria to produce isopentenol, a compound with desirable gasoline properties. The finding is a significant step toward developing a bacterial strain that can yield industrial quantities of renewable bio-gasoline.
In a lab in Bavaria scientists are trying to chemically transform crab shells into a high performance biopolymer. This European research project, Chibio, turns the waste into a raw material and energy source.
During your lifetime, the cells in your body divide many trillions of times. Iain Cheeseman, an associate professor of biology at MIT, has spent his career studying how cells control this process, which is critical to ensuring that the correct genetic information is passed down from generation to generation.
