Giving time can give you time

A new study by Cassie Mogilner and co-authors found that spending time on others increases participants' feelings of 'time affluence.' This is because giving away time boosts one's sense of personal competence and efficiency, ultimately making people more willing to commit to future engagements despite their busy schedules.

Vitamin D deficiency and poorer lung function in asthmatic children treated with steroids

A new study found that asthma treatment with inhaled corticosteroids is less effective in children with vitamin D deficiency, leading to poorer lung function. Vitamin D supplementation may enhance the anti-inflammatory properties of corticosteroids, improving outcomes for asthmatic children.

Finished heart switches stem cells off

Researchers discovered a crucial switch controlling cardiac stem cell activity, enabling the growth of healthy hearts and potentially treating congenital defects. By silencing this switch, scientists hope to regenerate damaged adult hearts using lab-cultured replacement cells.

Noninvasive imaging technique may help kids with heart transplants

Cardiologists at WashU Medicine have developed a noninvasive imaging technique to detect coronary artery disease in pediatric heart transplant patients, reducing the need for invasive tests. The technique uses contrast-enhanced cardiac MRI to assess coronary arteries and has shown promising results, although further study is needed.

The ecology of natural gas

Researchers study natural gas impacts on drinking water, finding high methane concentrations near fracking sites. Gas leaks also cause soil changes, affecting urban ecosystems. The session discusses policy strategies to encourage cleaner natural gas distribution and reducing greenhouse gas emissions.

Salt cress genome yields new clues to salt tolerance

Researchers sequenced the salt cress genome, identifying genes that contribute to its high salt tolerance. The study sheds light on the genetic characteristics underlying plant stress tolerance, with potential applications for agricultural crop improvement.

Non-surgical treatment of common shoulder injury may increase chances of return-to-play

A new study suggests that nonsurgical treatment for common shoulder injuries like SLAP tears may be more effective than surgery in increasing the chances of return-to-play in baseball players. The researchers found that position players were more likely to return to competition at a higher rate than pitchers, with 73% vs 40% respectively.

Plasmonic chains act like polymers

Researchers at Rice University have discovered that plasmonic chains exhibit properties similar to polymers, with the arrangement of nanoparticles influencing their optical behavior. The study found that the addition of nanoparticles along the chain can alter the energy of super-radiant modes and affect the interaction between particles.

Sports 1, housework, 0

Research finds that while fathers may be more involved with their children through sports, they still tend to do the lion's share of household tasks and childcare responsibilities. The study, conducted by UCLA sociologists, suggests that traditional gender roles persist in middle-class families.
