Berkeley Lab researchers and their colleagues extend electron spin in diamond for incredibly tiny magnetic detectors

From brain to heart to stomach, the bodies of humans and animals generate weak magnetic fields that a supersensitive detector could use to pinpoint illnesses, trace drugs – and maybe even read minds. Sensors no bigger than a thumbnail could map gas deposits underground, analyze chemicals, and pinpoint explosives that hide from other probes.

Now scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley, working with colleagues from Harvard University, have improved the performance of one of the most potent possible sensors of magnetic fields on the nanoscale – a diamond defect no bigger than a pair of atoms, called a nitrogen vacancy (NV) center.

Reappraisal is a widely-used cognitive strategy that can help people to regulate their reactions to emotionally charged events. Now, new research suggests that reappraisal may even be effective in changing people’s emotional responses in the context of one of the most intractable conflicts worldwide: the Israeli-Palestinian conflict.

“Negative intergroup emotions play a crucial role in decisions that perpetuate intractable conflicts,” observes lead researcher Eran Halperin of the New School of Psychology at the Interdisciplinary Center in Israel. (more…)

Scientists Find Evidence That Human Ancestors Used Fire One Million Years Ago

300,000 years earlier than believed

An international team led by the University of Toronto and Hebrew University has identified the earliest known evidence of the use of fire by human ancestors. Microscopic traces of wood ash, alongside animal bones and stone tools, were found in a layer dated to one million years ago at the Wonderwerk Cave in South Africa. (more…)
