People punish generous group members by rejecting them socially — even though the generosity benefits everyone — because the “big givers” are nonconformists, according to a Baylor University study.
A team led by scientists at The Scripps Research Institute has identified a family of tiny RNA molecules that work as powerful regulators of the immune response in mammals. Mice who lack these RNA molecules lose their normal infection-fighting ability, whereas mice that overproduce them develop a fatal autoimmune syndrome.

A new study in PLOS ONE that examined food poisoning infection as-it-happens in mice revealed harmful bacteria, such as a common type of Salmonella, takes over beneficial bacteria within the gut amid previously unseen changes to the gut environment. The results provide new insights into the course of infection and could lead to better prevention or new treatments.
New research from Johns Hopkins suggests that bits of genetic material from plants eaten by mice can NOT enter the bloodstream intact as previous research from another institution had indicated.

The breakthrough paired a traditional nerve bridge graft with a novel combination of scar degrading and growth factor treatments to grow new nerve cells from the thoracic level to the lower spinal cord region.

In 2 large studies, the association between aspirin use and risk of colorectal cancer was affected by mutation of the gene BRAF, with regular aspirin use associated with a lower risk of BRAF-wild-type colorectal cancer but not with risk of BRAF-mutated cancer, findings that suggest that BRAF-mutant colon tumor cells may be less sensitive to the effect of aspirin, according to a study in the June 26 issue of JAMA.
Use of advanced treatment technologies for prostate cancer, such as intensity-modulated radiotherapy and robotic prostatectomy, has increased among men with low-risk disease, high risk of noncancer mortality, or both, a population of patients who are unlikely to benefit from these treatments, according to a study in the June 26 issue of JAMA.
Researchers at Boston University College of Health & Rehabilitation Sciences: Sargent College have identified a combinatorial therapeutic approach that has proven effective in treating muscular dystrophy in a mouse model.
According to a study of physicians’ attitudes about pain drugs published in The Journal of Pain, negative physician attitudes about opioid medications are closely associated with lower rates of prescribing and more favorable attitudes are linked with higher prescribing levels.
For treating the estimated 100 million Americans with chronic pain -- a population larger than those with heart disease, cancer and diabetes combined -- researched reported in The Journal of Pain shows that primary care physicians overwhelmingly prefer to prescribe non-steroidal anti-inflammatory medications (NSAIDS), in accordance with published clinical practice guidelines.
A Johns Hopkins study of more than 1,800 men ages 52 to 62 suggests that African-Americans diagnosed with very-low-risk prostate cancers are much more likely than white men to actually have aggressive disease that goes unrecognized with current diagnostic approaches. Although prior studies have found it safe to delay treatment and monitor some presumably slow-growing or low-risk prostate cancers, such “active surveillance” (AS) does not appear to be a good idea for black men, the study concludes.
Nursing homes with higher proportions of Black residents do worse financially and deliver lower-quality care than nursing homes with few or no Black residents, finds a new study in Health Services Research.
A study found that people who are blindfolded employ the same strategy to intercept a running ball carrier as people who can see, which suggests that multiple areas of the brain cooperate to accomplish the task.
Humans and their pet dogs are close, so close that they both develop a type of cancer called diffuse large B-cell lymphoma. In humans it’s the most common lymphoma subtype while in dogs, it’s one of the most common cancers in veterinary oncology.
An international team of astronomers has found that a nearby star previously thought to host two or three planets is in fact orbited by six or seven worlds, including an unprecedented three to five "super-Earths" in its habitable zone.
Jamie K. Teer, Ph.D., assistant member of the Cancer Biology and Evolution Program at Moffitt Cancer Center, and colleagues have developed a new streamlined method to rapidly identify the genetic changes in small protein fragments unique to melanoma cancer cells. These fragments can be used as targets for tumor-infiltrating lymphocytes that have been shown to reduce cancerous lesions.
Leading experts on water issues in the Western U.S. have come together to establish what is known about the future of Colorado River water, and to understand the wide range of estimates for future flows.
Researchers have demonstrated that a protein called caspase-2 is a key regulator of a signaling pathway that leads to cognitive decline in Alzheimer's disease. The findings, made in a mouse model of Alzheimer's, suggest that inhibiting this protein could prevent the neuronal damage and subsequent cognitive decline associated with the disease. The study was published this month in the online journal Nature Communications.
How much is too much? It depends on how you say it – especially on a restaurant menu. Cornell University research reveals that descriptions of portion size impacts how much we eat and how much we’re willing to pay for our food.

A new nanoscale transistor made by Michigan Technological University scientists could represent the next frontier in electronics.
Overweight or obese adolescents who were spoken to about their weight by their mothers and fathers were more likely to engage in binge eating and use unhealthy weight-control behaviors than teens whose parents spoke with them in terms of eating healthier, according to a study published in JAMA Pediatrics. “I often do not even have my pediatric patients weigh themselves facing the scale; the number is not the goal,” says Ashley Barrient, MEd, LPC, RD, LDN, dietician and bariatric counselor at Loyola Center for Metabolic Surgery & Bariatric Care. “Kids are overwhelmed by talk of weight and dieting and feel they cannot change the numbers. But if you talk with them about the whole family making healthy eating changes as a team, they feel supported and positive change happens more frequently.”
