| Slow research to understand fast change Posted: 17 May 2021 11:47 AM PDT A new open-access research collection reveals unexpected lessons drawn from decades of rich data from the Long Term Ecological Research (LTER) Network. |
| Proteins that predict future dementia, Alzheimer's risk, identified Posted: 17 May 2021 11:47 AM PDT The development of dementia late in life is associated with abnormal blood levels of dozens of proteins up to five years earlier, according to a new study. Most of these proteins were not known to be linked to dementia before, suggesting new targets for prevention therapies. |
| Clinical trial suggests convalescent plasma may improve survival with severe COVID-19 Posted: 17 May 2021 09:50 AM PDT A randomized double-blind controlled trial of convalescent plasma for adults hospitalized with severe COVID-19 found that mortality at 28 days in the treatment arm was half the rate seen in the control arm (12.6 percent vs. 24.6 percent), although treatment was not associated with other improvements in clinical status. |
| Alcohol may have immediate effect on atrial fibrillation risk, events Posted: 17 May 2021 09:49 AM PDT Alcohol appears to have an immediate -- or near-immediate -- effect on heart rhythm, significantly increasing the chance that an episode of atrial fibrillation (AFib) will occur, according to new research. |
| Lipid droplets help protect kidney cells from damage Posted: 17 May 2021 09:49 AM PDT Researchers have found out how microscopic structures called lipid droplets may help to prevent a high-fat diet causing kidney damage. The work in fruit flies opens up a new research avenue for developing better treatments for chronic kidney disease. |
| Cells from the center of tumors most likely to spread around the body Posted: 17 May 2021 09:49 AM PDT Cells from different parts of kidney tumors behave differently, and surprisingly, cells within the center of a tumor are the most aggressive and have the highest chance of spreading around the body. |
| Rare COVID-19 response in children explained Posted: 17 May 2021 09:47 AM PDT One of the enduring mysteries of the COVID-19 pandemic is why most children tend to experience fewer symptoms than adults after infection with the coronavirus. The immune system response that occurs in the rare cases in which children experience life-threatening reactions after infection may offer an important insight, a new study suggests. |
| Scientists find new way of predicting COVID-19 vaccine efficacy Posted: 17 May 2021 07:57 AM PDT Australian researchers have identified the immune response associated with protection from COVID-19 -- a discovery that may help cut the time it takes to develop new vaccines. |
| Sperm help 'persuade' the female to accept pregnancy Posted: 17 May 2021 07:26 AM PDT Sperm are generally viewed as having just one action in reproduction -- to fertilize the female's egg - but studies are overturning that view. |
| High-intensity intermittent training improves spatial memory in rats Posted: 17 May 2021 07:26 AM PDT Despite lower exercise volume, HIIT was as effective as endurance running for improving exercise capacity and spatial memory. Researchers found that activity-specific physiological adaptations in the muscles and increased signaling and neurogenesis in the hippocampus underlie these improvements. Findings also suggested that benefits can potentially be optimized by tailoring exercise time and intensity. |
| Engineered organism could diagnose Crohn's disease flareups Posted: 17 May 2021 07:26 AM PDT Researchers have engineered a bacterium capable of diagnosing a human disease, a milestone in the field of synthetic biology. |
| New epigenetic regulatory mechanisms involved in multiple myeloma growth Posted: 17 May 2021 07:26 AM PDT An international team of researchers has analyzed the function of the histone demethylase KDM5A in multiple myeloma, one of the three major hematological cancers, and clarified the mechanism by which it promotes myeloma cell proliferation. They also developed a novel KDM5 inhibitor and showed that it inhibits cancer cell growth in a myeloma mouse model. The researchers expect that new therapies targeting KDM5A will be developed in the future. |
| COVID-19 vaccination: Thrombosis can be prevented by prompt treatment, researchers report Posted: 17 May 2021 07:26 AM PDT A rare syndrome has been observed in people following vaccination against COVID-19. This involves thrombosis at unusual sites in the body, associated with a low thrombocyte count and a clotting disorder. In medical jargon, this syndrome is referred to as VITT (vaccine-induced thrombotic thrombocytopenia). Doctors at MedUni Vienna and Vienna General Hospital have now successfully treated an acute instance of this syndrome. |
| Zapping nerves with ultrasound lowers drug-resistant blood pressure Posted: 17 May 2021 05:36 AM PDT Brief pulses of ultrasound delivered to nerves near the kidney lowered blood pressure in people with drug-resistant hypertension. |
| Study shows online gambling soared during lockdown, especially among regular gamblers Posted: 17 May 2021 05:36 AM PDT Regular gamblers were more than six times more likely to gamble online compared to before the COVID-19 pandemic, according to new research. |
| Preemie boys age faster as men, study shows Posted: 17 May 2021 05:36 AM PDT Using an epigenetic clock, the researchers looked at the genes of 45 of those who were ELBW babies along with 47 who were normal birth weight when they were age 30 to 35 to compare their biological age, controlling for chronic health problems and sensory impairments. |
| How plankton hold secrets to preventing pandemics Posted: 17 May 2021 05:36 AM PDT Whether it's plankton exposed to parasites or people exposed to pathogens, a host's initial immune response plays an integral role in determining whether infection occurs and to what degree it spreads within a population, new research suggests. |
| Posted: 17 May 2021 05:36 AM PDT During an inflammatory response, things need to happen quickly: researchers have recently discovered that certain immune cells that function as security guards can use a shortcut to get from the tissue to lymph nodes. |
| Save our oceans to protect our health: Scientists call for global action plan Posted: 17 May 2021 05:36 AM PDT An interdisciplinary European collaboration called the Seas Oceans and Public Health In Europe (SOPHIE) Project has outlined the initial steps that a wide range of organizations could take to work together to protect the largest connected ecoInsystem on Earth. They call for the current UN Ocean Decade to act as a meaningful catalyst for global change, reminding us that ocean health is intricately linked to human health. |
| Researchers report first instance of COVID-19 triggering recurrent blood clots in arms Posted: 15 May 2021 10:46 AM PDT Researchers are reporting the first instance of COVID-19 triggering a rare recurrence of potentially serious blood clots in people's arms. |
