Health: Are the dice rolled before ten years of age? Researchers find that children who grew up in disadvantaged households will age in poorer health, even if their socio-economic status improves as adults.
Teens work very hard to create a favorable online image through careful selection of which photos, activities and links to post on Facebook and Instagram, according to a recent study. Content that makes them appear interesting, well-liked and attractive to their friends and peers is a primary goal.
Study dispels notion that social media displaces human contact - A new study shows no evidence for the proposition that social media crowds out face-to-face communication with those who ought to matter most, our close friends and family members, debunking the social displacement hypothesis.
New research on English Football suggests darker skin toned soccer players occupy positions thought to require athleticism whereas lighter skin toned players occupy positions requiring creativity and organizational skills
Did humans domesticate themselves? Human ‘self-domestication’ is a hypothesis that states that among the driving forces of human evolution, humans selected their companions depending on who had a more pro-social behavior. Researchers found out new genetic evidence for this evolutionary process.
Franzmeier et al. show that greater left frontal hub connectivity within the fronto-parietal control network is associated with greater resilience of cognitive performance during early stages of autosomal dominant & sporadic Alzheimer’s disease.
Humans will actually react pretty well to news of alien life. Across multiple studies, researchers found that reactions were significantly more positive than negative, and more reward vs. risk oriented.
Like the horse of Troy, scientists have developed a way to sneak synthetic cells right into tumor tissue, where they then begin producing cancer-fighting proteins from the inside. The technique was tested in both cell cultures and in mice, and found to be an effective treatment in both cases.
Researchers have developed a printing technique using cells and molecules normally found in natural tissues to create constructs that resemble biological structures, embedded in an ink similar to their native environment, that mimic body parts for tissue engineering or regenerative medicine.
A strip of paper can now indicate presence of pathogens, tumor DNA or any genetic signature of interest. 100-fold greater sensitivity, the ability to detect multiple targets at once, and other new features further enhance SHERLOCK's power for detecting genetic signatures- Broad institute, Harvard
"Our models indicate that between 1999 and 2015, half of the orangutan population (~100,000) was affected by logging, deforestation, or industrialized plantations. Although land clearance caused the most dramatic rates of decline, it accounted for only a small proportion of the total loss."
Women who work as cleaners or regularly use cleaning sprays or other cleaning products at home appear to experience a greater decline in lung function over time than women who do not clean, according to new research published in the American Journal of Respiratory and Critical Care Medicine.
Scientists Create a New Form of Light by Linking Photons. Photons typically don’t interact, but physicists bound three together in the lab. This new form of light could someday be used to build light crystals that could lead to intriguing new ways of communicating and computing
A free ride with Lyft didn't reduce the number of skipped doctor's appointments among Philly's Medicaid population, according to a study from UPenn. Further, just 85 of 288 people who answered reminder phone calls accepted the rides in the first place.
Researchers found that petroleum-based chemicals used in perfumes, paints and other consumer products can, taken together, emit as much air pollution in the form of volatile organic compounds as motor vehicles do.
South Korea introduced the so-called Cinderella Law in 2011, involving internet gaming shutdown between 12:00 and 06:00 AM for those below 16. Intending to curb 'Internet Addiction', a large scale analysis now shows no reduction as well as internet usage now exceeding that of 2011 for the age group.
Scientists may have found the region of the brain most important for the sense of rhythm. When part of the brain tied to movement was temporarily disabled, people struggled to detect changes in rhythm.
Poor fitness linked to weaker brain fiber, higher dementia risk - A new study suggests that the lower the fitness level, the faster the deterioration of vital nerve fibers in the brain. This deterioration results in cognitive decline, including memory issues characteristic of dementia patients.
Psychologists clash over how easy it is to implant false memories of committing a crime. Reliance on mundane false memories has been problematic for experts who believe that false memories have critical real world consequence
Nearly 150,000 orangutans vanished over 16 years - “Worryingly, however, the largest number of orangutans were lost from areas that remained forested during the study period. This implies a large role of killing.”
A treatment program for opioid addiction launched by the Rhode Island Department of Corrections was associated with a significant drop in drug overdose deaths after inmates were released—and contributed to an overall drop in overdose deaths statewide, a new study finds.
Ninety percent of all attempts to treat the dependence or abuse of alcohol result in relapse within four years. A study on neurochemical changes associated with alcohol addiction finds that glutamate, a neurotransmitter, may play a role in alcohol relapse and addiction.
Researchers discover brain cells change following close contact with a stressed individual. Health-care workers treating soldiers with post-traumatic stress disorder (PTSD) report that some soldiers' partners and family members display symptoms of PTSD despite never serving in the military.
Researchers have created a chemical "remote control" for on-demand pain relief. They implanted special bioengineered cells in mice that respond to spearmint. When the mice smelled spearmint, the cells released a toxin originally found in Chinese bird spiders. The toxin is a natural pain reliever.
Researchers Reverse Alzheimer's in Mouse Models - The study, published in Journal of Experimental Medicine, found that by removing BACE-1 enzyme, amyloid plaque in brains of mice with Alzheimer's disease not only stopped building up, but also dissolved away without affecting neuro-development.
Some people disturbed by the 2016 election suffered a loss of appetite, trouble sleeping and concentrating, and have become easily annoyed, while others equally disturbed by the election have not experienced such symptoms of depression. A new study explains the differences between these two groups.
Surgical instruments may spread Alzheimer’s proteins - a study of eight people suggests that unclean instruments may sometimes lead to a rare and potentially fatal kind of brain bleeding disorder, cerebral amyloid angiopathy (CAA), published in Acta Neuropathologica.
