Breakthrough simplifies design of gels for food, cosmetics and biomedicine
(Phys.org) —Scientists at the University of Strathclyde and City University of New York have created methods that dramatically simplify the discovery of biological gels for food, cosmetics and biomedicine, as published ...
Crystallizing the DNA nanotechnology dream: Scientists have designed the first large DNA crystals
DNA has garnered attention for its potential as a programmable material platform that could spawn entire new and revolutionary nanodevices in computer science, microscopy, biology, and more. Researchers have been working ...
Quantum mechanical calculations reveal the hidden states of enzyme active sites
Enzymes carry out fundamental biological processes such as photosynthesis, nitrogen fixation and respiration, with the help of clusters of metal atoms as "active" sites. But scientists lack basic information about their function ...
Getting more electricity out of solar cells
(Phys.org) —When sunlight shines on today's solar cells, much of the incoming energy is given off as waste heat rather than electrical current. In a few materials, however, extra energy produces extra electrons—behavior ...
Where did all the xenon go?
(Phys.org) —The noble gas xenon should be found in terrestrial and Martian atmospheres, but researchers have had a hard time finding it.
Finding new ways to make drugs
Chemists have developed a revolutionary new way to manufacture natural chemicals and used it to assemble a scarce anti-inflammatory drug with potential to treat cancer and malaria.
Switchable material could harness the power of the sun—even when it's not shining
It's an obvious truism, but one that may soon be outdated: The problem with solar power is that sometimes the sun doesn't shine.
Chemists develop 'nanoreactor' for discovering new chemical reactions
(Phys.org) —In 1952, the famous Urey-Miller experiment mixed together chemicals that were present early in Earth's history, then approximately replicated the environmental conditions on the planet at that time to see if ...
Understanding natural compounds
Antibiotic-resistant germs, dangerous viruses, cancer: unsolved medical problems require new and better drugs. Nature can provide the inspiration for new active agents. A computer-based method developed by a team of researchers ...
'Sticky' ends start synthetic collagen growth
Rice University researchers have delivered a scientific one-two punch with a pair of papers that detail how synthetic collagen fibers self-assemble via their sticky ends.
