Layered controls can significantly curb exposure to COVID-19

Posted: 13 Apr 2022 11:16 AM PDT

Using a new computational model that simulates the life cycle of pathogen-laden particles, researchers found that a combination of distancing of six feet, universal mask-wearing, and increased room ventilation could reduce the risk of infection by more than 98 percent in more than 95 percent of scenarios studied.

New polymer materials make fabricating optical interconnects easier

Posted: 13 Apr 2022 10:12 AM PDT

Researchers have developed new polymer materials that are ideal for making the optical links necessary to connect chip-based photonic components with board-level circuits or optical fibers. These materials can be used to easily create interconnects between photonic chips and optical printed circuit boards, the light-based equivalent of electronic printed circuit boards.

Engineers have developed a heat engine with no moving parts that is as efficient as a steam turbine. The design could someday enable a fully decarbonized power grid, researchers say.

Hubble sheds light on origins of supermassive black holes

Posted: 13 Apr 2022 10:08 AM PDT

Astronomers have identified a rapidly growing black hole in the early universe that is considered a crucial "missing link" between young star-forming galaxies and the first supermassive black holes. They used data from NASA's Hubble Space Telescope to make this discovery.

Scientists demonstrate that some tropical plants have potential to remove toxic heavy metals from the soil

A team of researchers has demonstrated that some plant species could help to remove toxic heavy metals and metalloids from contaminated soil.

Undersea detector proves it’s swell

Posted: 13 Apr 2022 07:42 AM PDT

Highly energetic particles called muons are ever present in the atmosphere and pass through even massive objects with ease. Sensitive detectors installed along the Tokyo Bay tunnel measure muons passing through the sea above them. This allows for changes in the volume of water above the tunnel to be calculated. For the first time, this method was used to accurately detect a mild tsunami following a typhoon in 2021.

Real-time ultrafast humidity sensing optical sensor

Early research into the growing electronic sports (esports) industry highlights a need for better coaching to prevent burnout among professional players.

Feel the attraction of zwitterionic Janus Particles

Posted: 13 Apr 2022 06:09 AM PDT

Researchers have created a more accurate computer simulation of double-faced nanoparticles that form self-assembled structures based on electrostatic attraction. By including temporary charge fluctuations, compact clusters are shown to be a possible outcome, which may lead to new smart nanomaterials.

A 4 V-class metal-free organic lithium-ion battery gets closer to reality

Posted: 13 Apr 2022 06:08 AM PDT

Organic, metal free, high-energy batteries are a pathway to a greener future. Yet scientists have struggled to find ways to boost the voltage in organic lithium-ion batteries. Now, a study has proposed a small organic molecule known as croconic acid that can maintain a working voltage of around 4 Volts.

Study explores effects of extended spaceflight on brain

Posted: 12 Apr 2022 11:11 AM PDT

Scientists from the U.S., Europe and Russia are part of a team releasing the results of a large collaborative study involving the effects of long duration spaceflight on the brain.

Method efficiently breaks down plastic bottles into component parts

Posted: 12 Apr 2022 11:09 AM PDT

A research team has demonstrated that a material called a metal-organic framework (MOF) is a stable and selective catalyst for breaking down polyester-based plastic into its component parts. Only three things are needed: plastic, hydrogen and the catalyst. An important bonus is that one of the component parts the plastic is broken down into is terephthalic acid, a chemical used to produce plastic.
