Identical twins share over 99 percent of the same genetic material, which can make them ideal subjects for studying how other factors besides genetics can affect health. A new study by the San Francisco State University Kinesiology Department, CSU Fullerton, and Cal Poly, Pomona finds that 30 years of strenuous exercise made one twin much healthier than the other, with one exception.
Researchers have reversed wrinkled skin and hair loss, hallmarks of aging, in a mouse model. When a mutation leading to mitochondrial dysfunction is induced, the mouse develops wrinkled skin and extensive, visible hair loss in a matter of weeks. When the mitochondrial function is restored by turning off the gene responsible for mitochondrial dysfunction, the mouse returns to smooth skin and thick fur, indistinguishable from a healthy mouse of the same age.
Highly cooperative and generous people can attract hatred and social punishment, especially in competitive environments, new University of Guelph study finds.
Exposure to secondhand smoke is causing thousands of still births in developing countries, according to new research carried out by the University of York.
Those with conservative leanings tend to favor preservation of socio-economic order and social hierarchy. This can influence the demand for luxury products positioned as having the ability to maintain one's status.
Greening vacant urban land significantly reduces feelings of depression and improves overall mental health for the surrounding residents, researchers show in a new randomized, controlled study published in JAMA Network Open. The findings have implications for cities across the United States, where 15 percent of land is deemed "vacant" and often blighted or filled with trash and overgrown vegetation.
Physical conditions in a neighborhood matter. Trash, a lack of sidewalks and parks, and vacant or dilapidated spaces have been associated with depression, while living near green spaces has been associated with less depression, anxiety and stress. In Philadelphia, a citywide cluster randomized trial looked at whether greening vacant urban land by getting rid of trash, grading the land, planting new grass and some trees, and installing low wooden fencing could improve self-reported mental health.
A recent study in North Carolina found that in the first two weeks after being released from prison, former inmates were 40 times more likely to die of an opioid overdose than someone in the general population.
Morris Animal Foundation-funded researchers suspected and have now confirmed that plague vaccine bait, designed to protect prairie dogs and assist with recovery efforts of the black-footed ferret, is readily consumed by thousands of small rodents each year but with no apparent ill effect. Results were recently published in the journal EcoHealth.
New research from the University of Chicago Booth School of Business finds that when it comes to predicting who is most likely to act in a trustworthy manner, one of the most important factors is the anticipation of guilt.
