Free online tool calculates risk of COVID-19 transmission in poorly-ventilated spaces

The vital role of ventilation in the spread of COVID-19 has been quantified by researchers, who have found that in poorly-ventilated spaces, the virus spreads further than two meters in seconds, and is far more likely to spread through prolonged talking than through coughing.

Amber-encased fossil shines light on evolution of bioluminescent insects

Trapped in amber for ~100 million years, an exceptionally well-preserved, light-producing beetle sheds light on the diversification of bioluminescent beetles in the Cretaceous period and provides the missing fossil link between fireflies' living relatives.

Light-induced twisting of Weyl nodes switches on giant electron current

Scientists at the U.S. Department of Energy's Ames Laboratory and collaborators at Brookhaven National Laboratory and the University of Alabama at Birmingham have discovered a new light-induced switch that twists the crystal lattice of the material, switching on a giant electron current that appears to be nearly dissipationless. The discovery was made in a category of topological materials that holds great promise for spintronics, topological effect transistors, and quantum computing.

Most effective pollinator of Hoya pottsii revealed

Hoya, with around 300 species, is the largest genus in Asclepiadoideae tribe Marsdenieae in the family Apocynaceae. Hoya species produce white flowers, strong nocturnal fragrance and abundant nectar. The pollination of two Hoya species has been studied previously, but little is known about the specific nature and interactions between flower morphology, pollinators, and their environment.

Scientists streamline process for controlling spin dynamics

Marking a major achievement in the field of spintronics, researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Yale University have demonstrated the ability to control spin dynamics in magnetic materials by altering their thickness. The study, published today in Nature Materials, could lead to smaller, more energy-efficient electronic devices.

Going with the grains to explain a fundamental tectonic force

A new study suggests that tiny, mineral grains—squeezed and mixed over millions of years—set in motion the chain of events that plunge massive tectonic plates deep into the Earth's interior.

What the lungfishes' genome teaches us about the vertebrates' conquest of land

Using cutting-edge DNA sequencing technologies, a group of laboratories in Konstanz, Würzburg, Hamburg and Vienna, led by evolutionary biologist Professor Axel Meyer from the University of Konstanz, have fully sequenced the genome of the Australian lungfish. The genome, with a total size of more than 43 billion DNA building blocks, is nearly 14 times larger than that of humans and the largest animal genome sequenced to date. Its analysis provides valuable insights into the genetic and developmental evolutionary innovations that made it possible for fish to colonize land. The findings, published online in the journal Nature, expand our understanding of this major evolutionary transition in the Devonian ~420 million years ago.

How short circuits in lithium metal batteries can be prevented

There are high hopes for the next generation of high energy-density lithium metal batteries, but before they can be used in our vehicles, there are crucial problems to solve. An international research team led by Chalmers University of Technology, Sweden, has now developed concrete guidelines for how the batteries should be charged and operated, maximizing efficiency while minimizing the risk of short circuits.
