A professor of chemical and biomolecular engineering has summarized methods of making zeolites in the lab and examined how the emergence of data analytics and machine learning are aiding zeolite design.
Researchers say that an experimental dendrimer nanoparticle treatment called OP-101 substantially reduced the risk of death and need for a ventilator in a study of 24 severely ill adults hospitalized with COVID-19.
The discovery of how to shift damaged brain cells from a diseased state into a healthy one presents a potential new path to treating Alzheimer's and other forms of dementia, according to a new study.
Whether networks with a high level of cooperation emerge in a community depends on how quickly individuals leave -- for example, because they are exploited by others. Researchers investigated this problem by modeling a well-known cooperation game. They consider a spatial network, where players can relocate between different patches if they judge the local conditions to be unfavorable.
North Carolina State University researchers released findings from an analysis of 284 different studies on the challenges and best practices for teaching K-12 classes online—an effort launched during the COVID-19 pandemic to help teachers and administrators as they transitioned rapidly to online instruction.
Materials scientists have recently discovered a new mechanism to increase the strength and ductility of a high-entropy alloy, two properties which normally vary inversely with each other. The findings provide important insights for the future design of strong yet ductile high-entropy alloys and high-entropy ceramics.
A new analysis by education researchers reveals best practices and challenges for online K-12 education.
Findings from a new study offer a new potential method for cleaning wastewater after use by textiles, cosmetics or other industries.
Researchers had a solution, but they also had a problem. They had created a novel and highly promising material to improve the success of vascular grafts, but they needed a better way to test how well it worked.
Compelling new research challenges the deeply ingrained idea that diet alone should be adequate for everyone seeking to shed pounds. A new rigorous study has the potential to help reshape the science of weight-loss programs so they can be personalized for individual patients with difficult-to-treat obesity.
It's no surprise that hard physical labor wears you out, but what about hard mental labor? Sitting around thinking hard for hours makes one feel worn out, too. Now, researchers have new evidence to explain why this is, and, based on their findings, the reason you feel mentally exhausted (as opposed to drowsy) from intense thinking isn't all in your head.
DNA damage caused by factors such as ultraviolet radiation affect nearly three-quarters of all stem cell lines derived from human skin cells, say researchers, who argue that whole genome sequencing is essential for confirming if cell lines are usable.
Researchers and entrepreneurs have developed an implant made of collagen protein from pig's skin, which resembles the human cornea. In a pilot study, the implant restored vision to 20 people with diseased corneas, most of whom were blind prior to receiving the implant. The promising results bring hope to those suffering from corneal blindness and low vision by providing a bioengineered implant as...
Scientists found marble-sized chunks of rock in an asteroid sample that wouldn't disintegrate. They realized that these pebbles are physical evidence of a mysterious geological process first spotted on the asteroid Bennu by NASA's OSIRIS-REx spacecraft: asteroids shooting gravel out into space.
A new study reveals that a peptide produced by some legumes helps them control nitrogen-fixing bacteria by sequestering all available heme, an iron-containing molecule. This sends the bacteria into an iron-starvation mode that ramps up their production of ammonia, the form of nitrogen that is usable for plants.
Researchers have developed a new enzyme engineering platform to improve plastic degrading enzymes through directed evolution.
How can biodiversity be preserved whilst securing the economic livelihood of smallholder farmers growing vanilla in Madagascar? There is a way, according to a new study. The research team shows that vanilla plantations established on fallow land do not differ in terms of yield from those established in the forest. Cultivation on fallow land also increases biodiversity there.
New algorithm forces turbines in wind farms to be team players, boosting energy output overall.
In mouse studies, researchers find that excess alcohol consumption alters gut microbiome but latter is not directly or significantly linked to liver disease.
The thick layer of ice that has covered a Swiss mountain pass for centuries will have melted away completely within a few weeks, a ski resort said Thursday.
After decades of inaction in the face of escalating natural disasters and sustained global warming, Congress hopes to make clean energy so cheap in all aspects of life that it's nearly irresistible. The House is poised to pass a transformative bill Friday that would provide the most spending to fight climate change by any one nation ever in a single push.
Wildfire has ravaged the Western United States throughout the last decade. Over three million acres have already burned across the country this year. As fires spark earlier and extend further into autumn each year, turning from "fire seasons" to "fire years," the National Interagency Fire Center reports that many Western U.S. regions show above-average fire potential.
Blue marlin (one of the largest fish) and sailfish (one of the fastest fish) provide some of the most prized fights in the sportfishing world, making catching them with rod and reel one of those "once in a lifetime" experiences. Their distinctive elongated front-end bill gives them a built-in sword-like weapon for hunting, and thus the moniker "billfish".
Saildrones, so-called "robot surfboards," will be guided into hurricanes in the Atlantic for the second straight year, with the goal of improving storm forecasts.
