The last time you watched a spider drop from the ceiling on a line of silk, it likely descended gracefully on its dragline instead of spiraling uncontrollably, because spider silk has an unusual ability to resist twisting forces. In a new paper appearing this week in Applied Physics Letters, from AIP Publishing, researchers from China and […]

Mapping how words leap from brain to tongue

When you look at a picture of a mug, the neurons that store your memory of what a mug is begin firing. But it’s not a pinpoint process; a host of neurons that code for related ideas and items — bowl, coffee, spoon, plate, breakfast — are activated as well. How your brain narrows down […]

An international team of researchers bioengineering human liver tissues uncovered previously unknown networks of genetic-molecular crosstalk that control the organ’s developmental processes — greatly advancing efforts to generate healthy and usable human liver tissue from human pluripotent stem cells. The scientists report online in Nature on June 14 that their bioengineered human liver tissues still […]

One of the many tragedies of war are the dangers that persist long after conflicts formally end — dangers like abandoned minefields peppered with active, deadly ordnance. Buried landmines threaten the lives of ordinary people near former battlefields all over the world, and disarming them has always been a dangerous effort. Now, researchers at the […]

Zika virus is a mosquito-borne infectious disease linked to certain birth defects in infants in South and Central America and the United States. A Lawrence Berkeley National Laboratory (Berkeley Lab) researcher, Banumathi Sankaran, worked as part of a multi-institutional team to map a key viral protein called NS5. Necessary to virus reproduction, NS5 contains two […]

The study is the first large-scale analysis of chloride trends in freshwater lakes. It was conducted by a team of fifteen researchers as part of the Global Lake Ecological Observatory Network (GLEON) Fellowship Program, an initiative that seeks to train the next generation of freshwater scientists and practitioners. Lead author Hilary Dugan, a limnologist at […]
