Scientists Say Your Organs Don’t Grow Old Slowly—They Age in Two Sudden Bursts. Here’s When. - Popular Mechanics

It’s weird to think there was a time when people didn’t logically assume that inhaling cigarette smoke several times a day didn’t have some kind of native effect on the body. Some doctors even recommended smoking at one point. Now we know smoking causes a range of issues, like cancer and emphysema. But those are the broad implications that affect everyone. According to new research, cigarettes can impact our reproductive organs, but those impacts may affect men and women differently. A study published in Frontiers in Toxicology by researchers at the Universities of Nottingham and Sheffield looked at how cigarette smoke extract affected male and female mice over twelve weeks. The team found that while tobacco smoke wrecks reproductive health across the board, regardless of whatever factors you threw in front of it, it does operate through distinct biological routes depending on sex.

A large study led by Rutgers researchers has identified a possible vision risk associated with widely used diabetes and weight loss medications, including Ozempic and Wegovy. The findings suggest that people taking these drugs may face a slightly higher risk of developing a rare eye condition that can cause sudden and potentially permanent vision loss. The condition, known as ischemic optic neuropathy, occurs when blood flow to the optic nerve is reduced. Because the optic nerve carries visual information from the eye to the brain, damage to it can lead to significant vision problems.
