Anticoagulant has beneficial side-effects for COVID-19 patients, study finds Posted: 12 Nov 2021 09:25 AM PST Clotting problems and resulting complications are common in COVID-19 patients. Researchers have now shown that a member of the anticoagulant group of drugs not only has a beneficial effect on survival of COVID-19 patients, but also influences the duration of active infection with the SARS-CoV-2 coronavirus. |
Coronavirus lurks and lingers in nursing home patients’ rooms, study finds Posted: 12 Nov 2021 09:25 AM PST Even though most COVID-19 cases come from exposure to airborne coronavirus, a new study points to the importance of surfaces as a reservoir of risk in nursing homes -- especially certain objects close to the beds of patients who have COVID-19. |
Malaria: New knowledge about naturally acquired immunity may improve vaccines Posted: 12 Nov 2021 09:14 AM PST When you have become immune to malaria after having contracted the disease, it seems that the body uses a more efficient protection than if you have been vaccinated against the deadly disease. The researchers believe the new findings may be used to improve existing malaria vaccines. |
Noninvasive brain biopsy shows improved sensitivity in tumor detection Posted: 12 Nov 2021 07:05 AM PST A team of researchers has developed a noninvasive diagnostic method that may one day replace the biopsy with a simple blood test. |
More evidence of an evolutionary ‘arms race’ between genes and selfish genetic elements Posted: 12 Nov 2021 07:05 AM PST Researchers discover further evidence of an evolutionary arms race within organisms -- and the mechanisms at play in this arms race -- to combat selfish genetic elements. |
Posted: 12 Nov 2021 07:05 AM PST Climate change is altering familiar conditions of the world's oceans and creating new environments that could undermine efforts to protect sea life in the world's largest marine protected areas. |
Obesity raises the risk of gum disease by inflating growth of bone-destroying cells Posted: 12 Nov 2021 05:31 AM PST Chronic inflammation caused by obesity may trigger the development of cells that break down bone tissue, including the bone that holds teeth in place, according to new research that sought to improve understanding of the connection between obesity and gum disease. The study, completed in an animal model and published in October in the Journal of Dental Research, found that excessive inflammation resulting from obesity raises the number of myeloid-derived suppressor cells (MDSC), a group of immune cells that increase during illness to regulate immune function. MDSCs, which originate in the bone marrow, develop into a range of different cell types, including osteoclasts (a cell that breaks down bone tissue). |
Low-cost medicine effective in treating high blood pressure for some Posted: 11 Nov 2021 02:11 PM PST Medical researchers found that chlorthalidone was effective in lowering blood pressure in individuals with advanced kidney disease. |
Moderate amounts of caffeine not linked to maternal health risks Posted: 11 Nov 2021 02:11 PM PST Consuming a low amount of caffeine during pregnancy could help to reduce gestational diabetes risk, according to researchers. |
Competing quantum interactions enable single molecules to stand up Posted: 11 Nov 2021 02:11 PM PST Nanoscale machinery has many uses, including drug delivery, single-atom transistor technology, or memory storage. However, the machinery must be assembled at the nanoscale which is a considerable challenge for researchers. |
PFAS exposure, high-fat diet drive prostate cells’ metabolism into pro-cancer state Posted: 11 Nov 2021 12:43 PM PST A high-fat diet synergizes with exposure to PFAS to change the metabolism of benign and malignant prostate cells, according to a new study in mice. |
ESR-STM on single molecules and molecule-based structures Posted: 11 Nov 2021 12:43 PM PST Researchers extend single-atom electron spin resonance with STM from atoms to molecules, opening the power of synthetic chemistry to engineer their quantum states. |
Conflicting health information compromises attention and emotional responses Posted: 11 Nov 2021 12:42 PM PST The 24-hour news cycle and social media bombardment often resulting in conflicting messages about health issues might be making it harder than ever for people to make critical decisions, according to a new study. |
Posted: 11 Nov 2021 12:42 PM PST Breast cancers that have an overactive PI3K enzyme tend to be more aggressive and to spread and divide more like stem cells. But a new study uncovers a surprising relationship between PI3K activity and mutations in the PIK3CA gene that codes for the enzyme. |
Students who repeat a grade experience more bullying, study finds Posted: 11 Nov 2021 12:42 PM PST Students who have repeated a grade have higher risks of being victims of bullying in countries around the world, according to a new study of nearly half a million students. |
Coal creation mechanism uncovered Posted: 11 Nov 2021 12:42 PM PST The mechanism behind one of the first stages of coal creation may not be what we thought it was, according to a team of researchers who found that microbes were responsible for coal formation and production of methane in these areas, which has implications for methane fuel recovery from some coal fields. |
Scientists discover sugar molecule on HIV-infected cell plays role in evading immune system Posted: 11 Nov 2021 12:42 PM PST A new study shows how key features on the surface of HIV-infected cells help the disease evade detection by the immune system. It also shows how these features can be disabled. |
Unstable housing, homelessness associated with COVID-19 re-infection Posted: 11 Nov 2021 10:04 AM PST New study results demonstrate that unstable housing and homelessness is associated with a two-fold greater chance of being re-infected with SARS-CoV-2 compared to those who are securely housed. The research indicates that unstable housing was the only demographical factor associated with re-infection despite the presence of antibodies from the first infection. |
Simple silicon coating solves long-standing optical challenge Posted: 11 Nov 2021 10:04 AM PST Researchers have developed a silicon coating that, when applied to the surface of a glass lens, can counteract the effects of dispersion. |
Sea urchins' ballistic escape from predators Posted: 11 Nov 2021 10:04 AM PST New research shows that sea urchins, albeit having a limited and ancestral sensory system, can show a complex behaviour when escaping a predator. These marine invertebrates tend to move slowly and with unpredictable movements, but when they smell a predator, they escape following a ballistic motion -- straightforward, quick and directional -- to escape the threat. |
Posted: 11 Nov 2021 10:04 AM PST A new study shows that there are species of marine animals such as fish, crustaceans and mollusks (for example, squid) that change their habitats and deepen an average of 55 meters across the climatic gradient of the Mediterranean (spanning a range of 6 degrees C). |
New study finds evidence of COVID antibodies in breast milk of vaccinated mothers Posted: 11 Nov 2021 10:03 AM PST Researchers found that two groups of mothers -- those who had disease-acquired immunity and those with vaccine-immunity -- had high levels of antibodies in their breast milk, and these antibodies provided neutralization against SARS-CoV-2. |
Gut microbiota differences seen in people with autism may be due to dietary preferences Posted: 11 Nov 2021 10:03 AM PST Research suggested that autism spectrum disorder (ASD) may be at least partly caused by differences in the composition of the gut microbiota, based on the observation that certain types of microbes are more common in people with autism. But a new study suggests that the link may actually work the other way around: the diversity in species found in the guts of children with autism may be due to their restricted dietary preferences associated with autism, rather than the cause of their symptoms. |
Sustainable, biodegradable glitter – from your fruit bowl Posted: 11 Nov 2021 10:03 AM PST Researchers have developed a sustainable, plastic-free glitter for use in the cosmetics industry -- and it's made from the cellulose found in plants, fruits, vegetables, and wood pulp. |
Lingering COVID symptoms in young, competitive athletes rare, large study finds Posted: 11 Nov 2021 10:02 AM PST A new study shows that persistent symptoms following COVID-19 infections in collegiate athletes appear to be rare. Also rare is chest pain upon return to exercise, but is nonetheless a concerning finding that may warrant further clinical workup. |
