Senescent cells undergo an irreversible and permanent arrest of cell division and are hallmarks of both the aging process and multiple chronic diseases. Senescent cells -- and more importantly the factors they secrete, known collectively as the senescence-associated secretory phenotype (SASP) -- are widely accepted as drivers of aging and multiple age-related diseases. A new … [Read more...]
Neuron Found in Mice Could Have Implications for Effective Diet Drugs
Ever eaten something, gotten sick and then didn't want to eat that food again because of how it made you feel? That's because a signal from the gut to the brain produced that sickness, creating a taste aversion. Conventional wisdom renders there's one circuit in the brain that suppresses eating -- it comes from the stomach and makes you feel sick if you activate it too hard. … [Read more...]

TV Could Sway Viewers to Prefer Thinner Women: Study
People who watch lots of TV prefer thinner women, which suggests that TV can influence opinions about preferred body shapes, researchers say. Their study included 299 men and women in a remote area of Nicaragua, in Central America. Participants were either regular TV viewers or had little or no access to it. While regular viewers preferred thinner females, those with little or … [Read more...]
Permanent hair dye and straighteners may increase breast cancer risk
Scientists at the National Institutes of Health found that women who use permanent hair dye and chemical hair straighteners have a higher risk of developing breast cancer than women who don't use these products.

Long-term study finds faster breast cancer radiation treatment as effective as long course
A shorter course of higher-dose radiation treatment to part of the breast is showing promise in women with early-stage breast cancer who undergo breast conserving surgery, says a study led by Hamilton researchers. Accelerated partial breast irradiation (APBI) sees larger doses of radiation delivered to parts of the breast affected by cancer. This treatment takes place in … [Read more...]

Skiers have lower incidence of depression and vascular dementia — but not Alzheimer’s
Half as many diagnosed with depression, a delayed manifestation of Parkinson's, a reduced risk of developing vascular dementia -- but not Alzheimer's. These connections were discovered by researchers when they compared 200,000 people who had participated in a long-distance cross-country ski race between 1989 and 2010 with a matched cohort of the general population. The results … [Read more...]
Critical process for how breast cancer spreads in bones
Once breast cancer spreads to bone, treatment becomes nearly impossible. Breast cancer cells can lie dormant in the bone, often undetectable and able to escape typical treatments. Unfortunately, these dormant cells can awaken at any time to generate tumors. All of this combined makes it difficult to understand how the cells proliferate and how to stop them from doing … [Read more...]
Data-driven definition of unhealthy yet pervasive ‘hyper-palatable’ foods
A popular U.S. brand of potato chips once promoted itself with the slogan, "betcha can't eat just one!" Maybe that's because potato chips, like so many foods in the American diet, can pack a mix of ingredients apt to light up people's brain-reward neural circuitry and overpower mechanisms that are supposed to signal when we've had enough to eat. Researchers call this … [Read more...]
