Scientists have redefined how the key blood-clotting protein fibrinogen behaves when it contacts air, overturning two decades of scientific consensus on wound healing. It is the culmination of more than a decade of international collaboration by Dr. Richard Campbell of The University of Manches...
Slash, aka Saul Hudson, is probably best known as the guitarist for Guns N' Roses. But there's more to Slash than his music. He's also a lifelong reptile lover and an avid supporter of zoos and museums.
All living things have a fleet of tiny copy machines that turn instructions from DNA into RNA molecules responsible for helping build proteins that keep organisms alive. One of those nanoscale machines, called eukaryotic RNA polymerase II, performs a crucial early step required by nearly every b...
Low concentrations of caustic soda (sodium hydroxide, NaOH) are more efficient than high doses for preparing organic waste for biogas production. This finding increases methane production, reduces reagent consumption and, consequently, diminishes process costs and minimizes the risk of inhibitin...
Researchers from the MPIK in Heidelberg used an atomic gas as a time-dependent lens to shape and spectrally manipulate intense high-frequency laser pulses. This gas-based optical element could pave the way toward better XUV- and X-ray pulse control for applications such as chemical reaction stee...
