Newly detected air pollutant mimics damaging effects of cigarette smoke

A previously unrecognized group of air pollutants has been discovered that can cause life-threatening conditions similar to those found in tobacco smoke. Inhaling these pollutants exposes individuals to potentially lethal amounts of free radicals, with the average person inhaling 300 times more daily than from smoking one cigarette.

Researchers create safer alternative to heparin

Researchers at Rensselaer Polytechnic Institute have developed a fully synthetic heparin alternative that is safer and more pure than traditional heparin. The new version uses a process called chemoenzymatic synthesis to replicate the natural biosynthesis of heparin, resulting in a higher dose and lower risk of contamination.

Suicidal thoughts among college students more common than expected

A recent survey found that over half of college students reported having at least one episode of suicidal thinking, while 15% seriously considered attempting suicide. The study suggests that interventions should be offered at multiple points, not just during crisis, to address the entire continuum of suicidal thoughts and behaviors.
