| Researchers train computers to predict the next designer drugs Posted: 15 Nov 2021 09:35 AM PST Researchers have trained computers to predict the next designer drugs before they are even on the market, technology that could save lives. Identifying these so-called 'legal highs' within seized pills or powders can take months, during which time thousands of people may have already used a new designer drug. But new research is already helping law enforcement agencies around the world to cut identification time down from months to days, crucial in the race to identify and regulate new versions of dangerous psychoactive drugs. |
| COVID patients on SSRI antidepressants are less likely to die, study finds Posted: 15 Nov 2021 09:35 AM PST A large analysis of health records from 87 health care centers across the United States found that people taking a class of antidepressants called selective serotonin reuptake inhibitors (SSRIs), particularly fluoxetine, were significantly less likely to die of COVID-19 than a matched control group. |
| Ultra-large single-crystal WS2 monolayer Posted: 15 Nov 2021 09:35 AM PST A new technique opens a possibility to replace silicon with 2D materials in semiconducting technology. |
| This light-powered catalyst mimics photosynthesis Posted: 15 Nov 2021 09:35 AM PST By mimicking photosynthesis, researchers have designed a new type of photocatalyst that can absorb light and use it to help catalyze a variety of chemical reactions that would otherwise be difficult to perform. |
| Posted: 15 Nov 2021 09:35 AM PST New research has shown the drug losartan, normally used to treat high blood pressure (hypertension), is not effective in slowing down the progression of Alzheimer's disease (AD) in people with mild-to-moderate disease after 12 months of treatment. However, the drug could still be of benefit if prescribed for longer and if given to people with very early disease. |
| Researchers target a mouse’s own cells, rather than using antibiotics, to treat pneumonia Posted: 15 Nov 2021 09:35 AM PST Researchers have discovered a therapy that targets host cells rather than bacterial cells in treating bacterial pneumonia in rodents. The method involves white blood cells of the immune system called macrophages that eat bacteria, and a group of compounds that are naturally produced in mice and humans called epoxyeicosatrienoic acids or EETs. |
| A key brain region responds to faces similarly in infants and adults Posted: 15 Nov 2021 09:35 AM PST In a functional magnetic resonance imaging study of babies ranging in age from two to nine months, researchers have found regions of the infant visual cortex that show strong preferences for either faces, bodies, or scenes, just as they do in adults. |
| Keeping chocolate milk smooth, stable without carrageenan Posted: 15 Nov 2021 09:35 AM PST Fat-free chocolate milk processed for the first time with high-pressure jet technology exhibits enhanced viscosity, stabilizing cocoa particles in the fluid and eliminating the need for adding a controversial emulsifier. That's the conclusion of a team of researchers, whose study suggests that the new technology can preclude the use of carrageenan in chocolate milk. The widely used food additive -- which helps keep the liquid smooth and well-mixed even after days sitting on a store shelf -- is not desired by many consumers, especially in organic chocolate milk. |
| Lab mimics molecule found in poppies Posted: 15 Nov 2021 09:35 AM PST An undergraduate leads the discovery of a way to synthesize a rare molecule drawn from poppies. The molecule could become a building block for painkillers and other drugs. |
| Posted: 15 Nov 2021 09:35 AM PST A simple surgical technique during cardiac surgery was associated with a 56 percent reduction in the incidence of an irregular heart rhythm known as atrial fibrillation that can lead to stroke, with no added risks or side effects, according to a new study. The findings suggest that the method, called posterior left pericardiotomy, has significant potential for preventing prolonged hospital stays and the need for additional interventions and drugs to reduce the risk of strokes and heart failure associated with atrial fibrillation. |
| Altered fat metabolism, enzyme, likely plays key role in Lou Gehrig’s disease Posted: 15 Nov 2021 09:35 AM PST A new study using genetically engineered mice and human cell and tissue samples has added to evidence that higher levels of inflammatory chemicals involved in fat metabolism occur in people with amyotrophic lateral sclerosis (ALS), the neuromuscular disorder, also known as Lou Gehrig's disease. |
| Where does gold come from? New insights into element synthesis in the universe Posted: 15 Nov 2021 09:34 AM PST How are chemical elements produced in our Universe? Where do heavy elements like gold and uranium come from? Using computer simulations, a research team shows that the synthesis of heavy elements is typical for certain black holes with orbiting matter accumulations, so-called accretion disks. The predicted abundance of the formed elements provides insight into which heavy elements need to be studied in future laboratories to unravel the origin of heavy elements. |
| Bulletproof fingerprint technology takes images in the round Posted: 15 Nov 2021 09:34 AM PST Experts have developed a unique method for retrieving high resolution images of fingermarks from curved objects like bullet casings that offers greater detail and accuracy than traditional forensic methods. |
| Posted: 15 Nov 2021 09:34 AM PST More than 70% of microplastics found in samples from oceans and rivers could come from the scientists collecting them. A new article investigates procedural contamination when sampling for microparticles in aquatic environments. The study shows that a significant amount of microplastics and microfibres from scientists' clothing and gear mixes with environmental pollution in the water samples. |
| Hubble tension: Showing the cracks in Gaussian Processes Posted: 15 Nov 2021 09:34 AM PST A new analysis of the Hubble constant to show that the Gaussian Processes data reconstruction technique may not actually be independent of all cosmological models -- and that it may be time to question the validity of model independence itself. |
| Liquid fuels from carbon dioxide Posted: 15 Nov 2021 09:34 AM PST A new electrocatalyst called a-CuTi@Cu converts carbon dioxide (CO2) into liquid fuels. Active copper centered on an amorphous copper/titanium alloy produces ethanol, acetone, and n-butanol with high efficiency. |
| Using T cells to target malignant brain tumors Posted: 15 Nov 2021 09:34 AM PST Doctors and scientists have successfully tested a neoantigen-specific transgenic immune cell therapy for malignant brain tumors for the first time using an experimental model in mice. |
| Dreaming of being an investment shark? Better figure out if you’re an ‘owl’ or a ‘lark,’ study finds Posted: 15 Nov 2021 09:34 AM PST If you're a night owl looking to invest in the next big startup, making that decision first thing in the morning might not be the best idea, according to a new study. |
| Larger conservation areas didn’t protect animals in central Africa Posted: 15 Nov 2021 09:31 AM PST Efforts to protect threatened and endangered species in central Africa might be more successful if they focused on a smaller geographic area, new research suggests. |
| Easternmost Roman aqueduct discovered in Armenia Posted: 15 Nov 2021 07:34 AM PST Archaeologists have discovered remains of a Roman arched aqueduct during excavation work on the Hellenistic royal city of Artashat-Artaxata in ancient Armenia. It is the easternmost arched aqueduct in the Roman Empire. |
| Simulations provide clue to missing planets mystery Posted: 12 Nov 2021 07:05 AM PST New supercomputer simulations show that after creating a ring, a planet can move away and leave the ring behind. Not only does this bolster the planet theory for ring formation, the simulations show that a migrating planet can produce a variety of patterns matching those actually observed in disks. |
| Singing, being male, and being an adult tend to produce more respiratory aerosols, study finds Posted: 11 Nov 2021 02:11 PM PST A new study measured respiratory particles produced from people singing or playing instruments. Is singing worse than talking when it comes to how many particles are being emitted? Yes, according to the study. And the louder one talks or sings, the worse the emissions. A person's age and whether they are male or female also affects their respiratory emissions, with males and adults emitting more airborne particles, on average, than females and minors. |
