Predicting infectious SARS-CoV-2 from diagnostic samples: People with COVID-19 are unlikely to spread the new coronavirus if more than eight days have passed since their symptoms began, according to experiments in monkey cells.
SARS-CoV-2 can infect & replicate in humans, but it doesn't spread in mice, which prevents scientists from using mice to try to develop new therapies. In a new study, researchers created mice expressing the human ACE2 receptor for SARS-CoV-2.
Men and Women Misperceive What the Opposite Sex Finds Attractive. Women overestimated men's preference for thinness in female partners. At the same time, men overestimated women's preference for muscularity in male partners.
Material scientists have designed patches for shoes that give them 20 to 35 percent more grip than typical sneakers or boots. This technology uses the ancient art of Japanese paper cutting, kirigami, and can be applied to everything from basketball sneakers to orthopedic shoes.
Researchers discover estrogen can make drinking alcohol more rewarding to female mice over males. Meanwhile, reducing certain estrogen receptors in the brain can diminish binge drinking behavior in female — and not male — mice. This study may explain why men and women experience alcohol differently.

First study of COVID-19 patients with diabetes shows that 10% die within seven days of hospital admission and two thirds are men.
Stranger harassment/street harassment, is associated with posttraumatic stress disorder symptoms in women. Stranger harassment was also associated with increased self-blame, shame, taking rape precautions, fear of men, and safety concerns, which in turn were all related to PTSD symptom severity.
Prosociality influences vaccination behavior: A study of polio resurgence in Israel suggests that communication of prosocial health outcomes could allay fears about vaccine risks.
Scientists explain why stress can age you on a cellular level
Genetic research offers insight into rise of first cities. It reveals how a high level of human movement in Asia not only led to the spread of ideas and material culture but to a more genetically connected society well before the rise of cities, not the other way around, as previously thought.
Pancreatic cancer cells ‘completely blocked’ at Cellular level: CRISPR-mediated genomic editing reduces overall ISGylation, impairing self-renewal of Pancreatic Cancer stem cells and their in-vivo tumorigenic capacity.
The ‘Reward Pathway’ Unlocked: Using a specialized magnetic resonance imaging sensor that can track dopamine levels, neuroscientists have discovered how dopamine released deep within the brain influences distant brain regions.
A Study demonstrated that Grape Seed Extract intake significantly reduced Fasting Blood Glucose, Total Cholesterol, LDL cholesterol, triglycerides, and CRP levels— improving glycemic control, reducing inflammation and optimizing body weight.
Long childhoods and extended parenting help young grow smarter: Scientists think that this period of childhood and adolescence, which gives us lots of time to explore, create, and learn, is a key reason why we are smart enough to learn skills that take years to master.
Prostate Cancer precision therapy: 9.6% of germline mutations missed by tumor-only testing in prostatecancer patients. 98% of germline mutations were clinically actionable.
The surfaces that kill bacteria and viruses
Salvage logging in burned forests can negatively affect habitat for white-headed woodpeckers (Dryobates albolarvatus), a species of conservation concern, but also meets socioeconomic demands for timber and human safety.
Researchers have created a sodium-ion battery that holds as much energy and works as well as some commercial lithium-ion battery chemistries. It can deliver a capacity similar to some lithium-ion batteries and to recharge successfully, keeping more than 80 percent of its charge after 1,000 cycles.
Spanish dig unearths human remains in hunt for Irish rebel lord
Scientists are developing mathematical and statistical approaches that use a range of data, from areas such as genomics and biochemistry, to reconstruct highly diverse gut microbial communities computationally.
Primary prevention if Sexual violence: Although risk reduction approaches that aim to prevent victimization can be important, a decrease in the number of actual and potential perpetrators in the population is necessary to achieve measurable reductions in the prevalence of sexual violence.
Research has found telomeres, protective caps on the ends of the strands of DNA -- of subjects who considered their mothers' parenting style as "cold" were on average 25% smaller compared to those who reported having a mother whose parenting style they considered "warm."
Germany's youth are open to Cultured Meat
Study finds "endocrine-disrupting" chemicals in pesticides, nonstick cookware, and fire retardants on fabrics may increase risk of celiac disease (gluten sensitivity) in young people.
Anammox bacteria allow wastewater to be used for generating electricity: Anammox bacteria can be persuaded to generate electricity from wastewater if they are grown on electrodes in the absence of nitrite.
Scientists analyzed seafloor sediment samples from the Gulf of Mexico. Some of these samples contained migrated gaseous hydrocarbons harboring microbial communities featuring bacteria & archaea that are well-known inhabitants of deep biosphere sediments.
Bacterial Communities Have Memory
Researchers have developed a deep-learning model that maps fuel moisture levels in fine detail across 12 western states, opening a door for better fire predictions. To see dryness unfold over time, can help reveal areas at greatest risk and “chart out candidate locations for prescribed burns.”
The more biotech science you know, the less you fear GMO crops, study finds | Genetic Literacy Project
Prescription drug costs steadily soar, yet price transparency is lacking: A new study found ‘continual, marked, annual increases’ of the country’s 49 most popular brand-name drugs. “It is especially concerning to see drugs in the same class having increases that appear to be coordinated.”
Black people find it more difficult than white people to listen to someone from a different racial group about issues like police treatment of minorities, according to an online study of Americans.
Women who are frequent social media users and who are less satisfied with their appearance are particularly likely to consider cosmetic surgery in the future, but social media use was a stronger predictor of women’s desire for cosmetic surgery than their body dissatisfaction.
Dragon docks at International Space Station 19 hours after NASA-SpaceX launch
A mass extinction event 360 million years ago was caused by a brief breakdown of the ozone layer that shields the Earth from damaging ultraviolet (UV) radiation, researchers conclude. This is a newly discovered extinction mechanism with profound implications for our warming world today.
As Millennials Near 40, They’re Approaching Family Life Differently Than Previous Generations
Youth who said they were teased or ridiculed about their weight increased their body mass by 33 percent more each year, compared to a similar group who had not been teased, according to researchers. The findings appear to contradict the belief that such teasing might motivate youth to change...
A conservative religious environment strongly increases the chances of adolescent porn viewing. The new study strengthens the findings of existing research by using multilevel data to account for important differences between individuals.
