DNA packaging directly affects how fast DNA is copied in cells

Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends signals through an unusual pathway, affecting the cell's ability to divide and grow. This opens up new doors to study how the copying of the DNA and its packaging are linked. These findings may help scientists to find therapies and medicines... Read more ›

Bystander CPR up to 10 minutes after cardiac arrest may protect brain function

The sooner a lay rescuer (bystander) starts cardiopulmonary resuscitation (CPR) on a person having a cardiac arrest at home or in public, up to 10 minutes after the arrest, the better the chances of survival and brain protection, according to an analysis of nearly 200,000 out-of-hospital cardiac arrest cases in the U.S. from 2013 to 2022.

Study reveals best timing for getting the RSV vaccine during pregnancy to protect newborns

Current guidelines recommend that pregnant people receive a vaccine against respiratory syncytial virus (RSV) -- which typically causes mild, cold-like symptoms in most adults but can be deadly for infants -- during weeks 32-36 of pregnancy. New research suggests that vaccination earlier in that time-frame, closer to 32 weeks, could provide the best protection for newborns against RSV. Read more ›

Fighting microplastics for a cleaner future

Creating sustainable chemicals and developing better waste management will contribute to better sustainability. This research is part of figuring out how to make green hydrogen available for waste management using catalysts. The research uses solvents in low amounts that also act as hydrogen sources to break down a specific class of plastics called condensation polymers, which include polyethylene terephthalate (PET) bottles, packaging, textiles, and 3D printing.

Fear of another heart attack may be a major source of ongoing stress for survivors

Fear of another heart attack was a significant ongoing contributor to how heart attack survivors perceive their health, according to a study. While anxiety and depression are recognized as common conditions after a heart attack, they did not explain the impact of fear of recurrence in this study. The researchers suggest that fear of another heart attack should be evaluated and addressed separately from depression and anxiety. Read more ›
