Mechanobiology: Enzyme micropump autonomously delivers insulin in response to glucose levels
'Quadruple helix' DNA discovered in human cells
In 1953, Cambridge researchers Watson and Crick published a paper describing the interweaving 'double helix' DNA structure - the chemical code for all life. Now, in the year of that scientific landmark's 60th Anniversary, ...
Blood test for cancer biomarkers using an electrochemical clamp assay
New hybrid material simplifies organic transistor design
Rethinking basic science of graphene synthesis shows route to industrial-scale production
A new route to making graphene has been discovered that could make the 21st century's wonder material easier to ramp up to industrial scale. Graphene—a tightly bound single layer of carbon atoms with super ...
Mechanism for aprotic sodium-air batteries
Chemists use high speed camera to fully explain high school explosion demonstration
Rare byproduct of marine bacteria kills cancer cells by snipping their DNA
(Phys.org) —Yale University researchers have determined how a scarce molecule produced by marine bacteria can kill cancer cells, paving the way for the development of new, low-dose chemotherapies.
Study shows novel pattern of electrical charge movement through DNA
Electrical charges not only move through wires, they also travel along lengths of DNA, the molecule of life. The property is known as charge transport.
Boron 'buckyball' discovered
The discovery 30 years ago of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion of nanotechnology research. Now, there appears to be a new ball on the pitch.
Scientists invent self-healing battery electrode
Researchers have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell ...
Improving the selective extraction of spent uranium in nuclear waste clean-up
Driven by the need to find ways of separating, recycling and reducing nuclear waste, chemists at The University of Nottingham are developing our understanding of how uranium interacts with elements from around the periodic ...
Wagon-wheel pasta shape for better LED: 'Rotelle' molecules depolarize light more efficiently than 'spaghetti'
One problem in developing more efficient organic LED light bulbs and displays for TVs and phones is that much of the light is polarized in one direction and thus trapped within the light-emitting diode, or ...
