Smallest, fastest-known RNA switches provide new drug targets
(Phys.org)—A University of Michigan biophysical chemist and his colleagues have discovered the smallest and fastest-known molecular switches made of RNA, the chemical cousin of DNA. The researchers say ...
Study provides insight into evolution of first flowers
(PhysOrg.com) -- Charles Darwin described the sudden origin of flowering plants about 130 million years ago as an abominable mystery, one that scientists have yet to solve.
Presto! Fast color-changing material may lead to more powerful computers (w/Video)
(PhysOrg.com) -- Researchers in Japan are reporting development of a new so-called "photochromic" material that changes color thousands of times faster than conventional materials when exposed to light.
Molecular switch that promotes heart cell maturation discovered
A molecular switch that seems to be essential for embryonic heart cells to grow into more mature, adult-like heart cells has been discovered.
Supercomputers help researchers identify key molecular switch that controls cell behavior
If scientists can control cellular functions such as movement and development, they can cripple cells and pathogens that are causing disease in the body.
A protein safeguards against cataracts
The refractive power of the human eye lens relies on a densely packed mixture of proteins. Special protective proteins ensure that these proteins do not clump together as time passes. When this protective ...
Dutch chemists develop switchable antibiotic
Scientists at the University of Groningen have developed an antibiotic whose activity can be controlled using light. It is possible to 'switch on' the substance immediately before use, after which it will slowly lose its ...
Salmonella uses protective switch during infection, research finds
For the first time, researchers have found a particular kind of molecular switch in the food poisoning bacteria Salmonella Typhimurium under infection-like conditions. This switch, using a process called S-thiolation, appear ...
Study reveals secrets of bacterial slime
(Phys.org) —Newcastle University scientists have revealed the mechanism that causes a slime to form, making bacteria hard to shift and resistant to antibiotics.
Scientists devise screening method to aid RNA drug development research
(Phys.org)—Scientists from the Florida campus of The Scripps Research Institute (TSRI) have developed a new method of screening more than three million combinations of interactions between RNA and small molecules to identify ...
Biophysicists unravel secrets of genetic switch
When an invading bacterium or virus starts rummaging through the contents of a cell nucleus, using proteins like tiny hands to rearrange the host's DNA strands, it can alter the host's biological course. The invading proteins ...
Protein associated with learning implicated in causing grasshoppers to swarm
New research has found that a protein associated with learning and memory plays an integral role in changing the behaviour of locusts from that of harmless grasshoppers into swarming pests.
The smallest conceivable switch: Targeted proton transfer within a molecule
For a long time miniaturization has been the magic word in electronics. Dr. Willi Auwaerter and Professor Johannes Barth, together with their team of physicists at the Technische Universitaet Muenchen (TUM), ...
Researchers invent a switch that could improve electronics
Researchers at the University of Pittsburgh have invented a new type of electronic switch that performs electronic logic functions within a single molecule. The incorporation of such single-molecule elements could enable ...
