Discovery changes how scientists think about plant cell wall formation
University of Georgia researchers have discovered that two proteins come together in an unexpected way to make a carbohydrate, a chain of sugar molecules, in plant cell walls. This fundamental discovery changes ...
Astrobiologists discover 'sweet spots' for the formation of complex organic molecules in the galaxy
(PhysOrg.com) -- Scientists within the New York Center for Astrobiology at Rensselaer Polytechnic Institute have compiled years of research to help locate areas in outer space that have extreme potential for ...
Manipulating single molecules to unravel secrets of protein folding
Physicists at the Technische Universitaet Muenchen (TUM) are opening a new window into the life of biological cells, using a technique that lets them grab the ends of a single protein molecule and pull, making ...
New complex offers potentially safer alternative for gene therapy delivery
Spontaneous ordering of DNA fragments in a special matrix holds the key to creating non-toxic gene therapy delivery vectors, according to a study recently published in the European Physical Journal E.
Novel alloy could produce hydrogen fuel from sunlight
Scientists from the University of Kentucky and the University of Louisville have determined that an inexpensive semiconductor material can be "tweaked" to generate hydrogen from water using sunlight.
Biology, materials science get a boost from robust imaging tool
Shape and alignment are everything. How nanometer-sized pieces fit together into a whole structure determines how well a living cell or an artificially fabricated device performs. A new method to help understand ...
New way of synthesizing organic chemicals mimics nature
Feasible use of methane as a raw material
A team of EU-funded researchers has moved one step closer to using methane as a raw material.
