| 'Information theory' recruited to help scientists find cancer genes Posted: 20 Apr 2021 10:11 AM PDT Using a widely known field of mathematics designed mainly to study how digital and other forms of information are measured, stored and shared, scientists say they have uncovered a likely key genetic culprit in the development of acute lymphoblastic leukemia (ALL). |
| Astronauts' mental health risks tested in the Antarctic Posted: 20 Apr 2021 09:15 AM PDT Astronauts who spend prolonged time alone in space face mental health stressors like loneliness, isolation and more. A psychologist developed the Mental Health Checklist, a self-reporting instrument for detecting mental health changes in isolated, confined, extreme environments. She's reporting results that show significant declines in positive emotions. |
| Reversal of blood droplet flight predicted, captured in experiments Posted: 20 Apr 2021 09:15 AM PDT To search for answers about how blood droplets from a gunshot wound can reverse direction while in flight, researchers explored the influence of propellant gases on blood backspatter. They report using numeric modeling to capture the behavior of gun muzzle gases and predict the reversal of blood droplet flight, which was captured experimentally. Their experiments also show the breakup of blood droplets, a future extension of their modeling efforts. |
| A gene finding links severe canine juvenile epilepsy to mitochondrial dysfunction Posted: 20 Apr 2021 09:15 AM PDT Researchers found a cause for severe epilepsy resulting in death in Parson Russell Terrier puppies at a few months of age. A change in the PITRM1 gene can lead to a dysfunction of mitochondria, the cellular energy pumps. Concurrently, amyloid-beta accumulation and widespread neurodegeneration associated with Alzheimer's disease were identified in the puppies' brains. Changes to the PITRM1 gene in humans also cause a severe but slowly progressing brain disease. |
| Review summarizes known links between endocrine disruptors and breast cancer risk Posted: 20 Apr 2021 09:15 AM PDT Exposure to certain endocrine-disrupting chemicals could elevate the risk of breast cancer, according to a new comprehensive systematic review of epidemiological research. However, for many chemicals, evidence is inconsistent or still limited. |
| Differing immune responses discovered in asymptomatic cases vs those with severe COVID-19 Posted: 20 Apr 2021 09:15 AM PDT Using data from the Human Cell Atlas, researchers have identified the differences in immune cells' response in those who had no symptoms compared to severe symptoms. |
| SARS-CoV-2: British variant is 45 percent more contagious than the original virus, study finds Posted: 20 Apr 2021 09:14 AM PDT Researchers compared the R (basic reproduction number) of the original SARS-CoV-2 virus with the R of the British variant, and found that the British variant is almost 1.5 times more infectious. |
| Chickens and pigs with integrated genetic scissors Posted: 20 Apr 2021 09:14 AM PDT Genetically engineered animals provide important insights into the molecular basis of health and disease. Research has focused mainly on genetically modified mice, although other species, such as pigs, are more similar to human physiology. Researchers have now generated chickens and pigs in which target genes in desired organs can be efficiently altered. |
| Is social media use a potentially addictive behavior? Maybe not Posted: 20 Apr 2021 09:14 AM PDT Frequent use of social media may not amount to the same as addiction, according to new research. |
| Organ tissues become increasingly immune throughout life Posted: 20 Apr 2021 09:14 AM PDT Researchers have offered new ways to think about the immune system. The research, which indicates organ tissues become increasingly immune throughout life, may begin to alter fundamental ideas regarding the rules of vaccination and the immune system's function within the body. |
| Role of physical, mental health in cognitive impairment Posted: 20 Apr 2021 09:14 AM PDT A recent study suggests that preserving physical and mental health helps older adults experiencing cognitive impairment stave off declines in cognitive engagement. |
| Study reveals roadmap of muscle decline with age Posted: 20 Apr 2021 09:14 AM PDT Scientists have produced a comprehensive roadmap of muscle aging in mice that could be used to find treatments that prevent decline in muscle mobility and function. |
| Overgrowth of gut yeast in newborns may increase asthma risk Posted: 20 Apr 2021 09:14 AM PDT An overgrowth of yeast in the gut within the first few months of life may cause changes to the immune system that increase the risk of asthma later on, shows a new study. |
| Our attention is captured by eye-glance Posted: 20 Apr 2021 06:29 AM PDT Researchers looked at the way we process human gaze, focusing on the estimation of the temporal duration of social interactions. They discovered that when we make eye contact with another person, our attention is solicited, causing a distortion in our temporal perception: time seems shorter than it really is. These results will make it possible to develop a diagnostic tool to evaluate the mechanisms at work in people who are sensitive to social gaze. |
| Cool and COVID-safe: How radiant cooling could keep our cities comfortable and healthy Posted: 20 Apr 2021 06:29 AM PDT A novel system of chilled panels that can replace air conditioning can also help reduce the risk of indoor disease transmission, new analysis suggests. |
| Individualized training is key for autistic adolescents learning to drive Posted: 20 Apr 2021 06:28 AM PDT A new study identified clear strengths and a series of specific challenges autistic adolescents experience while learning to drive. |
| Flushing a public toilet? Don't linger, because aerosolized droplets do Posted: 20 Apr 2021 06:28 AM PDT Because COVID-19 has been detected in urine and stool samples, public restrooms can be cause for concern. Researchers measured droplets generated from flushing a toilet and a urinal in a public restroom and found a substantial increase in the measured aerosol levels in the ambient environment with the total number of droplets generated in each flushing test ranging up to the tens of thousands. Due to their small size, these droplets can remain suspended for a long time. |
