The origins of roughness

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to…

Researchers discover a new biochemical compound that can break down environmental pollutants. Read More

New catalyst recycles greenhouse gases into fuel and hydrogen gas

Scientists have taken a major step toward a circular carbon economy by developing a long-lasting, economical catalyst that recycles greenhouse gases into ingredients that can be used in fuel, hydrogen gas, and other chemicals. The results could be revolutionary in the effort to reverse global warming, according to the researchers.…

Ultrasound device improves charge time and run time in lithium batteries

Researchers have developed an ultrasound-emitting device that brings lithium metal batteries, or LMBs, one step closer to commercial viability. Although the research team focused on LMBs, the device can be used in any battery, regardless of chemistry. Read More

Scientists pioneer new way to study exoplanets

A team of scientists using the Low Frequency Array radio telescope in the Netherlands has observed radio waves that carry the distinct signatures of aurorae, caused by the interaction between a star’s magnetic field and a planet in orbit around it. Read More

Russia’s Radio Sputnik airing in Kansas City

As the FBI and other federal agencies look for signs of Russian interference in the 2020 election, Russian propaganda is being transmitted on America’s airwaves. It’s happening in the middle of the country. Jeff Pegues reports. Read More

The search for extraterrestrial intelligence moves up a gear

Breakthrough Listen releases 2 petabytes of data from SETI survey of Milky Way

Breakthrough Listen announced its second major release of SETI data: a radio survey of the plane of the Milky Way and the galactic center. The public is urged to search the data for signals from intelligent civilizations. A former undergraduate initiated the analysis by looking at emissions from 20 nearby…

Fast-charging, long-running, bendy energy storage breakthrough

A new bendable supercapacitor made from graphene, which charges quickly and safely stores a record-high level of energy for use over a long period, has been developed. Read More

New green technology generates electricity ‘out of thin air’

Electrical engineers and microbiologists have created a device they call an ‘Air-gen.’ or air-powered generator, with electrically conductive protein nanowires produced by the microbe Geobacter. The Air-gen connects electrodes to the protein nanowires in such a way that electrical current is generated from the water vapor naturally present in the…
