Supercomputing movies have revealed how glycans -- molecules that make up a sugary residue around the edges of the SARS-CoV-2 spike protein -- act as infection 'gates' that open to allow access to our cell's receptors. |
| Understanding enzyme evolution paves the way for 'green' chemistry Posted: 19 Aug 2021 08:30 AM PDT Researchers have shown how laboratory evolution can give rise to highly efficient enzymes for new-to-nature reactions, opening the door for novel and more environmentally friendly ways to make drugs and other chemicals. |
| Antibodies block specific viruses that cause arthritis, brain infections Posted: 19 Aug 2021 08:30 AM PDT Researchers have found antibodies that protect against specific mosquito-borne viruses that cause arthritis and brain infections. The findings could lead to a universal therapy or vaccine for the viruses. |
| Rattlesnake rattles trick human ears Posted: 19 Aug 2021 08:30 AM PDT Rattlesnakes increase their rattling rate as potential threats approach, and this abrupt switch to a high-frequency mode makes listeners, including humans, think they're closer than they actually are, researchers report. |
| Landslide disaster risk in the Kivu Rift is linked to deforestation and population growth Posted: 19 Aug 2021 08:30 AM PDT New research shows how deforestation and population growth have greatly impacted landslide risk in the Kivu Rift. This is what researchers established from an analysis of six decades of forest cover and population trends in the region. |
| Teens who use cannabis frequently more likely to have premature baby Posted: 19 Aug 2021 07:27 AM PDT Teenagers who use cannabis frequently may be more likely to have children born preterm, when they become parents up to twenty years later, finds a new study. The research repeatedly assessed 665 participants in a general population cohort on their tobacco and cannabis use between ages 14 to 29 years, before pregnancy. |
| Increased snowfall will offset sea level rise from melting Antarctic ice sheet Posted: 19 Aug 2021 07:27 AM PDT A new study predicts that any sea level rise in the world's most southern continent will be countered by an increase in snowfall, associated with a warmer Polar atmosphere. Using modern methods to calculate projected changes to sea levels, researchers discovered that the two ice sheets of Greenland and Antarctica respond differently, reflecting their very distinct local climates. |
| Tracking water storage shows options for improving water management during floods and droughts Posted: 19 Aug 2021 07:27 AM PDT Researchers have created a balance sheet for water across the United States -- tracking total water storage in 14 of the country's major aquifers over 15 years. |
| Common solar tech can power smart devices indoors Posted: 19 Aug 2021 07:27 AM PDT Any time you turn on a light at home or in the office, you are expending electrical energy. But what if flipping the light switch meant providing other useful energy too? We usually think of solar, or photovoltaic (PV), cells fixed to roofs, converting sunlight into electricity, but bringing that technology indoors could further boost the energy efficiency of buildings and energize swaths of wireless smart technologies such as smoke alarms, cameras and temperature sensors, also called Internet of Things (IoT) devices. Now, a new study suggests that a straightforward approach for capturing light indoors may be within reach. |
| Study of tyrannosaur braincases shows more variation than previously thought Posted: 19 Aug 2021 07:26 AM PDT Scientists have used CT scans to digitally reconstruct the brain, inner ear, and surrounding bones (known as the braincase) of two well-preserved Daspletosaurus specimens. This massive tyrannosaur lived in the coastal forest of what is now Alberta around 75 million years ago -- preceding the more famous T. rex by about 10 million years. Their results suggest that dinosaur brains, and the bones enclosing and protecting, them vary more than previously thought within species, or among closely related species. |
| Measuring electric current in soil could provide answers on soil health Posted: 19 Aug 2021 07:26 AM PDT Researchers have developed a way to assess soil health by measuring the electric current produced by its tiniest microbes. They used a probe originally developed to measure the electrochemical signal of microbes in aquatic environments, and tested it on healthy and unhealthy soil samples to measure microbial metabolism and other indicators of soil health. This proof-of-concept research could someday lead to a simple, real-time test for farmers to determine whether soil is productive. |
| Humans managed shellfish and their predators for millennia Posted: 18 Aug 2021 05:02 PM PDT A new study confirms that for millennia, Indigenous people managed their relationship with shellfish and sea otters to safeguard their access to shellfish which remain important for food, social, and ceremonial uses today. |
| Developing enhanced fish vaccines with nanocellulose Posted: 18 Aug 2021 12:37 PM PDT Scientists are developing new fish vaccines using nanocellulose produced from Maine's wood pulp industry. Nanocellulose poses no known harmful effects to fish tissue and is unlikely to cause cellular damage. Fish vaccines made with nanocellulose may also be more effective and less expensive to produce than current vaccines made with adjuvants that are water and oil based, according to researchers. |
| How fructose in the diet contributes to obesity Posted: 18 Aug 2021 10:52 AM PDT Eating fructose appears to alter cells in the digestive tract in a way that enables it to take in more nutrients, according to a preclinical study. These changes could help to explain the well-known link between rising fructose consumption around the world and increased rates of obesity and certain cancers. |
| Posted: 18 Aug 2021 10:05 AM PDT With wind generation one of the fastest-growing renewable energy sectors in the world, experts are using machine learning and other signal processing techniques to characterize annoying noise features from wind farms. Two new publications from the ongoing Wind Farm Noise Study take another step towards improving wind turbine noise assessment methods, guidelines and wind turbine design to make wind energy more acceptable to surrounding communities. |
| Scientists dig deep to understand the effects of population pressure on violence levels Posted: 18 Aug 2021 10:05 AM PDT A continuous rise in global population has led to fears that conflicts and war will become more frequent as resources dwindle. But this widespread belief has not been quantified based on actual Japanese archaeological data, until now. Researchers have now examined the skeletal remains of people living in the Middle Yayoi period of Japan to set the record straight on the relationship between population pressure and the frequency of violence. |
| Treading wander paths to uncover the geological history of southwest Japan Posted: 18 Aug 2021 10:05 AM PDT The breakup of the supercontinent and formation of the current Afro-Eurasia landmass were caused by movement of Earth's tectonic plates. The position of these tectonic plates is preserved in magnetic fields in rocks. These remnant magnetic fields can help generate apparent polar wander paths (APWPs). Researchers have now constructed an APWP of southwest Japan and compared it to that of East Asia, shedding light on the interaction between the Asian continent and southwest Japan. |
