| How the timing of dinner and genetics affect individuals’ blood sugar control Posted: 25 Jan 2022 09:40 AM PST Eating dinner close to bedtime, when melatonin levels are high, disturbs blood sugar control, especially in individuals with a genetic variant in the melatonin receptor MTNR1B, which has been linked to an elevated risk of type 2 diabetes. The high melatonin levels and food intake associated with late eating impairs blood sugar control in carriers of the MTNR1B genetic risk variant through a defect in insulin secretion. |
| Liquid water beneath Martian south polar cap? Posted: 25 Jan 2022 09:40 AM PST Scientists measured the properties of ice-brine mixtures as cold as -145 degrees Fahrenheit to help confirm that salty water likely exists between grains of ice or sediment under the ice cap at Mars' south pole. Laboratory measurements support oddly bright reflections detected by the MARSIS subsurface sounding radar aboard ESA's Mars Express orbiter. |

| Most 'pathogenic' genetic variants have a low risk of causing disease Posted: 25 Jan 2022 08:25 AM PST Researchers discovered that the chance a pathogenic genetic variant may actually cause a disease is relatively low - about 7 percent. They also found that some variants, such as those associated with breast cancer, are linked to a wide range of risks for disease. The results could alter the way the risks associated with these variants are reported, and one day, help guide the way physicians interpret genetic testing results. |
| Using the eye as a window into heart disease Posted: 25 Jan 2022 08:25 AM PST Scientists have developed an artificial intelligence (AI) system that can analyze eye scans taken during a routine visit to an optician or eye clinic and identify patients at a high risk of a heart attack. Doctors have recognized that changes to the tiny blood vessels in the retina are indicators of broader vascular disease, including problems with the heart. In the research, deep learning techniques were used to train an AI system to automatically read retinal scans and identify those people who, over the following year, were likely to have a heart attack. |
| Sediments a likely culprit in spread of deadly disease on Florida coral reefs, study finds Posted: 25 Jan 2022 08:25 AM PST A new study found that seafloor sediments have the potential to transmit a deadly pathogen to local corals and hypothesizes that sediments have played a role in the persistence of a devastating coral disease outbreak throughout Florida and the Caribbean. |
| Viral proteins join forces to lower plants' defense 'shields' Posted: 25 Jan 2022 08:25 AM PST New research into how viral proteins interact and can be disabled holds promise to help plants defend themselves against viruses -- and ultimately prevent crop losses. The study found that viral proteins interact with each other to help a virus hijack its host plant and complete its life cycle. When some of these viral proteins were disabled, the researchers found that the virus could not move from cell to cell. |
| Posted: 25 Jan 2022 08:25 AM PST The analysis, based on 2016-2019 data survey responses covering nearly 132,000 children ages 3 to 17, examined the complex interplay between common mental health problems among children, social and relational health risks, and protective factors. |
| Southern Ocean storms cause outgassing of carbon dioxide Posted: 25 Jan 2022 08:25 AM PST Storms over the waters around Antarctica drive an outgassing of carbon dioxide into the atmosphere, according to a new international study. The research group used advanced ocean robots for the study, which provides a better understanding of climate change and can lead to better global climate models. |
| Ultrasound technique predicts hip dysplasia in infants Posted: 25 Jan 2022 08:25 AM PST A technique that uses ultrasound images to determine the depth and shape of the hip socket can accurately predict which infants with hip dysplasia will develop normal hip structure and which remain dysplastic, according to a new study. Researchers said statistical shape modeling improves on existing techniques and could spare many infants from unnecessary treatment. |
| New study suggests two paths toward 'super immunity' to COVID-19 Posted: 25 Jan 2022 08:25 AM PST New laboratory research reveals more than one path toward robust immunity from COVID-19. A new study finds that two forms of immunity -- breakthrough infections following vaccination or natural infection followed by vaccination -- provide roughly equal levels of enhanced immune protection. The research follows an earlier study that described extremely high levels of immune response following breakthrough infections -- so-called 'super immunity.' That study was the first to use multiple live SARS-CoV-2 variants to measure cross-neutralization of blood serum from breakthrough cases. |
| Scientists observe record high hydride ion conductivity using modified lanthanum trihydride Posted: 25 Jan 2022 08:25 AM PST Lanthanum trihydride, a compound of lanthanum and hydrogen, when lightly doped with oxygen shows potential as an efficient hydrogen carrier, according to a new study. Hydride ion (H--) conductors are expected to be used in chemical reactors and energy storage systems. However, the low H-- conductivity at room temperature introduces certain technical limitations. These limitations may now be overcome with this latest innovation by the researchers. |
| SARS-CoV-2: New insights into antibody response against viral variants Posted: 25 Jan 2022 08:25 AM PST Researchers present new findings on the immune response against the coronavirus SARS-CoV-2. Their study is based on investigations of antibodies elicited by infection with the Beta variant of the virus. The researchers conclude that the Beta variant can confer broad immunity to multiple viral strains, which could be beneficial for protection against the currently prevalent Delta and Omicron variants, as well as against future viral variants. |
| Can reactor fuel debris be safely removed from Fukushima Daiichi? Posted: 25 Jan 2022 06:30 AM PST Decommissioning and clean-up are ongoing at the Fukushima Daiichi Nuclear Power Plant (FDNPP); however, many difficult problems remain unaddressed. Chief amongst these problems is the retrieval and management of fuel debris. |
| Researchers identify immunological markers for SARS-CoV-2 reinfection Posted: 25 Jan 2022 06:30 AM PST Tracking new hotspots of SARS-CoV-2 will become more important as the virus evolves and becomes endemic. New variants may be more contagious than previous ones -- and escape vaccines. Serum biomarkers, identified in rhesus macaques, can differentiate between primary infection and reinfection. A tool utilizing these biomarkers may help identify surges in reinfection, scientists noted. |
| An unexpected attraction of nucleic acids and fat Posted: 25 Jan 2022 06:30 AM PST All cells on Earth are enveloped in a fatty layer of lipids. Lipid membranes protect the content of the cells, including genetic information such as RNA and DNA. A new study reveals how lipids and RNA can directly interact and how this regulates RNA activity in unexpected ways. The study could help explain how RNA could be regulated in primordial or synthetic biological systems and lead to improvements in the design of RNA vaccines. |
