Researchers have discovered a new layer of the human genome.
RNA and DNA are often separate molecules in cells, but sometimes the RNA is found embedded in DNA. It was always thought to be a mistake, but new research, published in Cell, is completely changing how scientists view these building blocks. The findings suggest that this hidden component influences DNA in ways we don’t yet understand.
Efforts to block inflammation may actually age you faster.
Researchers have attempted to slow the aging process by turning off a protein that triggers inflammation. Surprisingly, when scientists removed the protein in mice, the animals grew weaker, experienced more inflammation, and had shorter lifespans. The study, published in Nature Aging, revealed that while the protein triggers inflammation, it also prevents other instances of chronic inflammation associated with age-related diseases.
How accurate is your mental health diagnosis?
Research published in Frontiers in Psychiatry shows that when psychiatrists evaluated the exact same clinical symptoms, on average they only agree on the final diagnosis 55 percent of the time. This shows a dangerous gap in how physicians interpret symptoms. Researchers believe we need a more precise diagnostic system to reduce confusion and get patients the help they need.
Will your next ultrasound be at home?
Parents could soon monitor fetal heart rates using nothing more than their mobile phones. Researchers have developed an app that converts your smartphone speaker into a low-pitched doppler radar to detect small vibrations caused by a baby’s heartbeat. The app aims to fill critical monitoring gaps between checkups and provide vital reassurance during high-risk pregnancies. The research is published in The Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies.
