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. |
| 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. |
| Physicists discover method for emulating nonlinear quantum electrodynamics in a laboratory setting Posted: 07 Mar 2022 01:20 PM PST On the big screen, in video games and in our imaginations, lightsabers flare and catch when they clash together. That clashing, or interference, happens only in fiction -- and in places with enormous magnetic and electric fields, which happens in nature only near massive objects such as neutron stars. A team of physicists has discovered discovered that it is possible to produce this effect in a laboratory setting, using a class of novel materials. |
| Lead exposure in last century shrank IQ scores of half of Americans, study finds Posted: 07 Mar 2022 01:20 PM PST Researchers calculate that exposure to car exhaust from leaded gas during childhood stole a collective 824 million IQ points from over 170 million Americans alive today, more than half of the population of the United States. |
| Traffic accidents significantly dropped during COVID-19 lockdown, study finds Posted: 07 Mar 2022 10:19 AM PST Research shows that traffic accidents decreased by nearly half during the two-month period at the start of the COVID-19 pandemic when residents of most states were under a stay-at-home order. |
| Extending the battery life of small drones to strengthen security on U.S. Border Posted: 07 Mar 2022 10:04 AM PST To enhance security of the nation's border, a pioneer in drone technology is proposing a continuous flight of small drones over its perimeter with enhanced, wireless batteries to extend flying time. |
| 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. |
| Using raw materials more sustainably Posted: 07 Mar 2022 08:31 AM PST Insights into the oxidation of hydrocarbons at vanadium pentoxide pave the way for a new catalyst design. |
| Harnessing AI and Robotics to treat spinal cord injuries Posted: 07 Mar 2022 08:30 AM PST By employing artificial intelligence (AI) and robotics to formulate therapeutic proteins, a team has successfully stabilized an enzyme able to degrade scar tissue resulting from spinal cord injuries and promote tissue regeneration. The study details the team's ground-breaking stabilization of the enzyme Chondroitinase ABC, (ChABC) offering new hope for patients coping with spinal cord injuries. |
| Nanoparticle reduces skin and lung scarring for scleroderma, mouse study finds Posted: 07 Mar 2022 08:30 AM PST Researchers found a unique immune cell plays a key role in the chronic inflammation and scarring in the lungs and skin of people with scleroderma, or systemic sclerosis. After injecting mice with biodegradable PLG nanoparticles, which are used in medical sutures, researchers found that the nanoparticles specifically targeted these inflammatory cells and prevented skin and lung fibrosis. Researchers say it's a promising step towards targeted treatment for patients with early scleroderma. |
| Physicists publish on X-ray lasers taking pictures of complex molecules Posted: 07 Mar 2022 08:30 AM PST Physicists have used the world's largest X-ray laser to take pictures of complex molecules. With ultra-bright X-ray flashes, the scientists were able to take snapshots of gas-phase iodopyridine molecules with atomic resolution. In the process, the molecules are exploded by the X-ray laser, and the image is reconstructed from the pieces. |
| Tiny 'skyscrapers' help bacteria convert sunlight into electricity Posted: 07 Mar 2022 08:30 AM PST Researchers have made tiny 'skyscrapers' for communities of bacteria, helping them to generate electricity from just sunlight and water. |
| Safer, more powerful batteries for electric cars, power grid Posted: 07 Mar 2022 08:30 AM PST A new study tackled a long-held assumption that adding some liquid electrolyte to improve performance would make solid-state batteries unsafe. Instead, the research team found that in many cases solid-state batteries with a little liquid electrolyte were safer than their lithium-ion counterparts. They also found, if the battery were to short-circuit, releasing all its stored energy, the theoretically super-safe, all-solid-state battery could put out a dangerous amount of heat. |
| Lensless camera captures cellular-level, 3D details in living tissue Posted: 07 Mar 2022 08:29 AM PST The lensless Bio-FlatScope is a small, inexpensive camera to monitor biological activity that can't be captured by conventional instruments. The device could eventually be used to look for signs of cancer or sepsis or become a valuable endoscopy tool. |
| Posted: 07 Mar 2022 06:17 AM PST Scientists have long tried to use graphene, which is composed of carbon, as a kind of sieve. But this material doesn't have any pores. Now, a team has found an alternative material which comes with pores from the outset. |
| Electric Truck Hydropower, a flexible solution to hydropower in mountainous regions Posted: 07 Mar 2022 06:17 AM PST Researchers have developed an innovative hydropower technology based on electric trucks that could provide a flexible and clean solution for electricity generation in mountainous regions. |
| 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. |
| Self-sustained divertor oscillation mechanism identified in fusion plasma experiment Posted: 02 Mar 2022 06:27 AM PST To harness the forces that power the Sun, researchers heat fuel to such a high temperature that atoms melt into electrons and nuclei to form a hot, gaseous soup called plasma. The plasma can rip through any material on Earth, so it must be confined by magnetic fields -- but it can only be controlled for short periods. Now, in a first step to prolonged control, researchers have discovered that the underlying mechanism mirrors the unlikely biological predator-prey model. |
