Researchers have shown that a dental tool they created can measure the acidity built up by the bacteria in plaque that leads to cavities.

NASA's NICER telescope sees hot spots merge on a magnetar

Posted: 08 Mar 2022 10:05 AM PST

For the first time, NASA's Neutron star Interior Composition Explorer (NICER) has observed the merging of multimillion-degree X-ray spots on the surface of a magnetar, a supermagnetized stellar core no larger than a city.

How animal swarms respond to threats

With the help of microrobots, physicists decode how swarms of animals respond effectively to danger.

Toward ever-more powerful microchips and supercomputers

Posted: 08 Mar 2022 07:51 AM PST

A look at the process to extend 'Moore's law,' which has doubled the number of transistors that can be packed on a microchip roughly every two years, and develop new ways to produce more capable, efficient, and cost-effective chips.

Engineered light waves enable rapid recording of 3D microscope images

Posted: 08 Mar 2022 07:28 AM PST

Researchers have developed a new method for rapid 3D imaging. Instead of having to scan repeatedly in 2D, the researchers proposed a one-scan technique that uses a light needle to process at depth and laterally.

Astronomers discover largest molecule yet in a planet-forming disc

Posted: 08 Mar 2022 07:28 AM PST

Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers have for the first time detected dimethyl ether in a planet-forming disc. With nine atoms, this is the largest molecule identified in such a disc to date. It is also a precursor of larger organic molecules that can lead to the emergence of life.

Natural gas flares likely source of respiratory illness spike

Posted: 08 Mar 2022 07:27 AM PST

Flaring of natural gas from oil wells appeared to cause an increase of around 11,000 hospital visits for respiratory reasons in North Dakota, US, up to 60 miles away from oil drilling sites.

A new study from cognitive scientists offers an answer to why legal documents such as contracts or deeds are often so impenetrable.

Simulated human eye movement aims to train metaverse platforms

Posted: 07 Mar 2022 10:20 AM PST

Computer engineers have developed virtual eyes that simulate how humans look at the world accurately enough for companies to train virtual reality and augmented reality programs. Called EyeSyn for short, the program will help developers create applications for the rapidly expanding metaverse while protecting user data.

Carbon dioxide could be stored below ocean floor, research shows

Posted: 07 Mar 2022 08:31 AM PST

Scientists are searching for new technologies that could help the world reach carbon neutrality. One potential solution is to capture and store carbon dioxide emissions in the form of hydrates under ocean floor sediments, kept in place by the natural pressure created by the weight of the seawater above. Now researchers have demonstrated experimental evidence of the stability of carbon dioxide hydrates in oceanic sediments -- an essential step in making this carbon storage technology a viable reality.

Convenient wireless charging for home use

Posted: 04 Mar 2022 08:20 AM PST

A new wireless charging system can charge devices placed anywhere within a ring around it. Existing systems transfer power in a specific direction or to a specific position. By providing a donut-shaped charging field, the new system offers a more convenient and reliable design for consumer use.
