Highly efficient nanoparticles could bring down the cost of fuel cells
(Phys.org) —Fuel cells are a promising, non-polluting way to power cars, but their platinum catalysts are so expensive that there's no way current technology could be economically scaled up for widespread use. Now scientists ...
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.
New chemical sponge has potential to lessen the carbon footprint of oil industry
UK scientists have discovered a ground-breaking technique with the potential to dramatically reduce the amount of energy used in the refinement of crude oil.
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.
