| Clever biomolecular labelling enables identification of immune cells Posted: 07 Jun 2021 05:22 PM PDT Biomolecules regulate the biological functions inside every living cell. If scientists can understand the molecular mechanisms, then it is possible to detect severe dysfunction. At a molecular level, this can be achieved with fluorescent markers that are incorporated into the respective biomolecules. Researchers are now able to show that a complex of manganese makes it possible to conveniently label certain biomolecules. |
| Defying body clock linked to depression and lower wellbeing Posted: 07 Jun 2021 05:22 PM PDT People whose sleep pattern goes against their natural body clock are more likely to have depression and lower levels of wellbeing, according to a large-scale new study. |
| Monoclonal antibody prevents HIV infection in monkeys, study finds Posted: 07 Jun 2021 05:22 PM PDT The experimental, lab-made antibody leronlimab can completely prevent nonhuman primates from being infected with the monkey form of HIV, new research shows. The results will inform a future human clinical trial evaluating leronlimab as a potential pre-exposure prophylaxis, or PrEP, therapy to prevent human infection from the virus that causes AIDS. |
| A breakthrough in the physics of blood clotting Posted: 07 Jun 2021 05:22 PM PDT Understanding the physics of clot contraction could potentially lead to new ways to treat bleeding problems and clotting problems. |
| Posted: 07 Jun 2021 01:12 PM PDT A new study suggests a slowdown in the use of convalescent plasma to treat hospitalized COVID-19 patients led to a higher COVID-19 mortality during a critical period during this past winter's surge. |
| Protein identified as new therapeutic anti-viral target for COVID-19 Posted: 07 Jun 2021 01:11 PM PDT New research identified a novel interaction between the SARS-CoV-2 spike protein and the galectin-3-binding protein (LGALS3BP) which could be a new therapeutic anti-viral target. |
| Researchers find toxin from maple tree in cow's milk Posted: 07 Jun 2021 01:11 PM PDT Cows can pass on the hypoglycin A toxin through their milk, a study shows. The substance can cause severe symptoms in humans and animals. Small amounts of the toxin were detected in the raw milk of cows that grazed in a pasture exposed to sycamore maple. The team calls for further investigations to realistically assess the potential dangers. |
| Odds of stem cell transplant restoring fertility are as random as a coin toss -- until now Posted: 07 Jun 2021 01:10 PM PDT The chances of restoring fertility through sperm stem cell transplant are as random as a coin toss. But a team of scientists developed a new strategy that serves as a 'weighted coin' that can favorably rig the odds to achieve outcomes where fertility is successfully restored. |
| Carbon dioxide sensors in two urban areas registered big drop in emissions during COVID-19 pandemic Posted: 07 Jun 2021 01:10 PM PDT Carbon dioxide emissions in Los Angeles and the Washington DC/Baltimore regions fell roughly 33 percent in April of 2020 compared with previous years, as roads emptied and economic activity slowed due to the COVID-19 pandemic, according to a new study. But while the emissions reductions are significant, the method that scientists used to measure them may have the greater long-term impact. |
| Research advances one step closer to stem cell therapy for type 1 diabetes Posted: 07 Jun 2021 01:09 PM PDT Scientists are developing a promising approach for treating type 1 diabetes by using stem cells to create insulin-producing cells (called beta cells) that could replace nonfunctional pancreatic cells. |
| Trained viruses prove more effective at fighting antibiotic resistance Posted: 07 Jun 2021 01:09 PM PDT Research reveals that viruses known as bacteriophages that undergo special evolutionary training increase their capacity to subdue bacteria. The results provide hope in the ongoing battle against antibiotic resistance, a rising threat as deadly bacteria continue to evolve to render many modern drugs ineffective. |
| Computers can now predict our preferences directly from our brain Posted: 07 Jun 2021 08:03 AM PDT A research team demonstrates it is possible to predict individual preferences based on how a person's brain responses match up to others. This could potentially be used to provide individually tailored media content -- and perhaps even to enlighten us about ourselves. |
| Fundamental advance in understanding T cell immunity Posted: 07 Jun 2021 08:02 AM PDT Researchers have provided a fundamental advance regarding how T cells become activated when encountering pathogens such as viruses. |
| How coronavirus aerosols travel through our lungs Posted: 07 Jun 2021 08:02 AM PDT When we inhale isolated coronavirus particles, more than 65 percent reach the deepest region of our lungs, new research has discovered, and more of these aerosols reach the right lung than the left. |
| New drug to halt dementia after multiple head injuries Posted: 07 Jun 2021 08:01 AM PDT An international study has identified a new drug to stop athletes developing dementia after sustaining repeated head injuries in their career. |
| Regulation of protein homeostasis by cardiac glycosides Posted: 07 Jun 2021 06:57 AM PDT The unfolded protein response (UPR) is a pivotal mechanism to mitigate protein homeostasis through transcriptional or translational control. On the other hand, since dysregulation of UPR has been associated with various human diseases, the compounds modulating UPR can clarify the pathological significance of the UPR. |
| Posted: 07 Jun 2021 06:57 AM PDT To investigate the role genes play in the evolution of social structure, researchers created an experiment they likened to the 1998 film 'The Truman Show.' Genetically identical versions of 20 fruit flies were placed in 98 controlled enclosures, and video cameras recorded their interactions. The study revealed the same clones occupied the same social positions in each enclosure, regardless of living conditions, providing evidence that popularity is heritable. |
| Applying mathematics takes 'friendship paradox' beyond averages Posted: 07 Jun 2021 05:46 AM PDT In network science, the famous 'friendship paradox' describes why your friends are (on average) more popular, richer, and more attractive than you are. But a slightly more nuanced picture emerges when we apply mathematics to real-world data. |
| Researchers identify a molecule critical to functional brain rejuvenation Posted: 07 Jun 2021 05:46 AM PDT A new study has identified a molecule called ten-eleven-translocation 1 (TET1) as a necessary component in the repair of myelin, which protects nerves and facilitates accurate transmission of electrical signals. The discovery could have important implications in treating neurodegenerative diseases and for molecular rejuvenation of aging brains in healthy individuals. |
| Pandemic prevention measures linked to lower rates of Kawasaki disease in children Posted: 07 Jun 2021 05:46 AM PDT Rates of Kawasaki disease -- a condition that creates inflammation in blood vessels in the heart and is more common in children of Asian/Pacific Island descent -- have substantially decreased in South Korea during the COVID-19 pandemic, according to a new study. The decrease could be due to mask-wearing, hand-washing, school closures and physical distancing, suggesting Kawasaki disease may be prompted by infectious agents. |
| Controlling insulin production with a smartwatch Posted: 07 Jun 2021 05:46 AM PDT Researchers have developed a gene switch that can be operated with the green LED light emitted by commercial smartwatches. This revolutionary approach could be used to treat diabetes in the future. |
| Simple blood test can accurately reveal underlying neurodegeneration Posted: 07 Jun 2021 05:46 AM PDT A new study of over 3000 people, has shown for the first time that a single biomarker can accurately indicate the presence of underlying neurodegeneration in people with cognitive issues. |
| Attentive listening helps teens open up, study finds Posted: 04 Jun 2021 09:27 AM PDT Engaged listening techniques such as eye contact, nodding and using key words to praise openness helps teenagers when they admit bad behavior and share hurt feelings with their parents, a new study has shown. |
