Cellular memory of stressful situations

Stress is unhealthy. The cells use therefore a variety of mechanisms to deal with stress and avert its immediate threat. However, certain stressful situations leave marks that go beyond the immediate response; some even seem ...

Solar cell polymers with multiplied electrical output

One challenge in improving the efficiency of solar cells is that some of the absorbed light energy is lost as heat. So scientists have been looking to design materials that can convert more of that energy into useful electricity. ...

Imaging the genome: Cataloguing the fundamental processes of life

The team of researchers, led by Dr Rafael Carazo Salas from the Department of Genetics, combined high-resolution 3D confocal microscopy and computer-automated analysis of the images to survey the fission yeast genome with ...

Brewing yeasts reveal secrets of chromosomal warfare and dysfunction

Using two yeasts that have been used to brew tea and beer for centuries, researchers at Fred Hutchinson Cancer Research Center have revealed how reproductive barriers might rapidly arise to create species boundaries. Schizosaccharomyces ...

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 ...

Two for one in solar power

Solar cells offer the opportunity to harvest abundant, renewable energy. Although the highest energy light occurs in the ultraviolet and visible spectrum, most solar energy is in the infrared. There is a trade-off in harvesting ...

Safer nuclear fuels

Exploratory research on revolutionary new types of nuclear fuel pellets that would be safer in the event of a nuclear disaster has yielded promising results, according to a team of scientists from the University of Tennessee ...
