Scientists developing a prototype optical quantum hard drive have improved storage time by a factor of over 100. The team's record storage time of six hours is a major step towards a secure worldwide data encryption network based on quantum information
The quantum dots in these displays also use materials and technologies - including engineered nanoparticles and the heavy metal cadmium - that have been a magnet for health and environmental concerns. Will the dazzling pictures this technology allow blind us to new health and environmental challenges, or do their benefits outweigh the potential risks?
By taking advantage of natural body processes, researchers at UC Santa Barbara and MIT have developed a method of targeting inflamed tissues, creating a way to treat both the inflammation and its underlying cause.
Using neutron crystallography, a team of researchers unequivocally mapped the active site of the enzyme dihydrofolate reductase (DHFR), an enzyme necessary for nucleotide biosynthesis and a classical drug target.
Researchers derived a new set of equations that allows for calculating electron paramagnetic resonance (EPR) transition probabilities with arbitrary alignment and polarization of the exciting electromagnetic radiation.
To stay warm when temperatures drop outside, we heat our indoor spaces - even when no one is in them. But scientists have now developed a novel nanowire coating for clothes that can both generate heat and trap the heat from our bodies better than regular clothes.
Rather than soothe and comfort, a hot cup of tea or cocoa can cause people with sensitive teeth a jolt of pain. But scientists are now developing a new biomaterial that can potentially rebuild worn enamel and reduce tooth sensitivity for an extended period.
Life processes depend fundamentally on phenomena occurring on the membranes separating cells from their environment. Hitherto poorly understood, the mechanisms responsible for transport through the cell membrane will be able to be studied faster and more cheaply - thanks to a new microfluidic system. The system enables the serial formation of cell membranes and measurement of the processes taking place on them.
