Most U.S. adults have a “heart age” several years older than their chronological age — sometimes by more than a decade. And that gap is wider among men and among those with lower incomes or education or who identify as Black or Hispanic, according to a new study led by Northwestern Medicine.

A research team from NYU Tandon School of Engineering, NYU Abu Dhabi and other universities has developed an AI agent capable of autonomously solving complex cybersecurity challenges.

A new study in Nature shows that delivering a single injection of gene therapy at birth may offer years-long protection against HIV, tapping into a critical window in early life that could reshape the fight against pediatric infections in high-risk regions.

Ancient Roman concrete, which was used to build aqueducts, bridges, and buildings across the empire, has endured for over two thousand years. In a study publishing July 25 in the Cell Press journal iScience, researchers investigated whether switching back to Roman concrete could improve the sustainability of modern-day concrete production. They found that reproducing the ancient recipe would require comparable energy and water and emit similar amounts of CO2. However, the authors suggest that the heightened durability of Roman concrete might make it a more sustainable option because it could reduce the need for replacement and maintenance.

About The Study: Although nonsurgeon physicians have lower mortality rates than other highly educated professionals, this mortality benefit does not extend to surgeons. Because surgeons and nonsurgeon physicians have similar levels of health care knowledge and resources, higher mortality rates among surgeons might reflect differences related to work environment, professional demands, and lifestyle. The results of this study indicate that several causes of death (e.g., motor vehicle collisions), disproportionately affect surgeons, aligning with evidence that hazardous driving events associated with extended work hours are especially pronounced among surgeons.
