Temperature heals lithium dendrites

Rechargeable lithium-ion, the dominant battery technology for portable electronics, is increasingly becoming the battery of choice for electric-vehicle and electric-grid energy-storage applications. In a lithium-ion battery, the cathode (positive electrode) is a lithium metal oxide...

Robot takes cues from spider that can walk and roll

Once again, we get visual proof that it pays to check out Nature's outstanding engineering tricks in order to work up interesting machines that behave in innovative ways—for machines, that is. Esslingen, Germany-based Festo has...

Preventing tumors from shedding their identifying proteins allows immune system to attack

A team of researchers with the Dana-Farber Cancer Institute and Brigham and Women's Hospital in the U.S. has found that introducing an antibody into a cancerous mouse model prevented the escape of ligands from...

Researchers develop a novel RNA-based therapy to target West Nile virus

A Yale-led research team developed a new RNA therapy, delivered through the nose, to treat mice infected with West Nile Virus. The innovative approach reduced the virus in the brain, allowing the immune system to...

Opioid Epidemic and Fentanyl Deaths Soar is Getting Even Worse

The number of Americans dying from opioid overdoses continues to rise, with deaths from synthetic opioids such as fentanyl doubling in just a year, according to a new report. The report, published today (March 28) by the Centers...

Liquid Sculptures : How It Works

A mesmerizing new video shows scientists crafting dazzling, slinky-like sculptures made completely out of liquid — and the liquid structures can hold their shape for months. Researchers created the ghostly-looking sculptures by manipulating the properties...

Memory Researchers Link Two Brain Regions to Conceptual Organization

If your idea of a perfect dog is an abstract rendering of canine qualities extracted across many encounters in your life, you are not alone in how your brain connects memories, say University of...

Can the causal order between events change in quantum mechanics?

Researchers at the University of Vienna and the Austrian Academy of Sciences develop a new theoretical framework to describe how causal structures in quantum mechanics transform. They analyse under which conditions quantum mechanics allows the...

New Material : be invisible to infrared night vision tools

Materials inspired by disappearing Hollywood dinosaurs and real-life shy squid have been invented by UCI engineers, according to new findings in Science this Friday. The thin swatches can quickly change how they reflect heat, smoothing or wrinkling...

Dietary supplement shows promise for reversing cardiovascular aging

Scientists have long known that restricting calories can fend off physiological signs of aging, with studies in fruit flies, roundworms, rodents and even people showing that chronically slashing intake by about a third can...
