The research team identified an association between the polygenic risk score and radiographic progression, an observation that was pronounced in people with a younger age of onset of rheumatoid arthritis. |
| Simulated human eye movement aims to train metaverse platforms Posted: 07 Mar 2022 10:20 AM PST Computer engineers have developed virtual eyes that simulate how humans look at the world accurately enough for companies to train virtual reality and augmented reality programs. Called EyeSyn for short, the program will help developers create applications for the rapidly expanding metaverse while protecting user data. |
| The secret to longevity? Ask a yellow-bellied marmot Posted: 07 Mar 2022 10:19 AM PST A new study shows that aging slows to a crawl when yellow-bellied marmots hibernate. These large ground squirrels are able to virtually halt the aging process during the seven to eight months they spend hibernating in their underground burrows, the researchers report. The study is the first to analyze the rate of aging among marmots in the wild. |
| A speed limit could be a breakthrough for stem cell therapy Posted: 07 Mar 2022 10:19 AM PST One of the most promising approaches to replacing sick or damaged cells with healthy cells is cellular reprogramming, whereby one cell type in our body converts to another cell type. Research has uncovered new ways to improve the cellular reprogramming efficiency, unlocking potential for cellular repair therapies. |

| Field-based patient trial for cell-free Zika testing delivers highly accurate results Posted: 07 Mar 2022 08:30 AM PST Researchers have led one of the first field trials for a synthetic biology-based diagnostic using patient samples. This work, conducted on-site in Latin America, reveals the potential for cell-free synthetic biology tools and companion hardware for providing rapid, de-centralized, and low-cost patient testing for infectious diseases like the Zika virus. |
| Optimism may promote emotional well-being by limiting how often one experiences stressful situations Posted: 07 Mar 2022 05:23 AM PST 'Don't worry, be happy,' is more than just song lyrics. A growing body of evidence supports an association between optimism and healthy aging, but it is unclear how optimism impacts health. When it comes to dealing with day-to-day stressors, such as household chores or arguments with others, a new study has found that being more or less optimistic did not make a difference in how older men emotionally reacted to or recovered from these stressors. However, optimism appeared to promote emotional well-being by limiting how often older men experience stressful situations or changing the way they interpret situations as stressful. |
