- The DNA markers from the blood of healthy centenarians are more similar to those of people in their 20s than people in their 70s. These differences could someday be used to determine biological age — whether a person’s body functions as older or younger than their chronological age. https://news.brown.edu/articles/2018/12/aging 24 comments science
- Brain-computer interface enables people with paralysis to control tablet devices - Three clinical trial participants with paralysis chatted with family and friends, shopped online, and used other tablet computer applications just by just thinking about pointing and clicking a mouse. http://news.brown.edu/articles/2018/11/tablet 24 comments science
- Despite widespread use of the "smiley face" pain scale in clinics, some researchers say a more empirical approach would be better. A new electroencephalography-based test could offer a better way for patients to rate their pain and could also ease the over-prescription of opioids, a new study shows. https://news.brown.edu/articles/2018/11/pain 15 comments science
- The number of patients with end-stage kidney disease who died within a year of starting dialysis decreased in states that expanded Medicaid coverage in the wake of the Affordable Care Act, according to a new study. https://news.brown.edu/articles/2018/10/dialysis 106 comments science
- Just a few drinks of alcohol can change how memories are formed. Researchers found that alcohol hijacks a conserved memory pathway in the brain and changes which versions of genes are made, forming the cravings that fuel addiction. https://news.brown.edu/articles/2018/10/alcohol 440 comments science
- Ancient Mars had right conditions for underground life, new research suggests - the breakdown of water molecules trapped in ancient Martian rocks likely produced enough chemical energy to sustain microorganisms for hundreds of millions of years beneath the Red Planet’s surface. https://news.brown.edu/articles/2018/09/radiolysis 3 comments space
- Rapid-onset gender dysphoria in adolescents and young adults may spread through groups of friends or online sources, and may be a harmful coping mechanism like drugs, alcohol or cutting, a new study suggests. More research is needed to determine whether it is temporary or likely to be long term. https://news.brown.edu/articles/2018/08/gender 3314 comments science
