For those who menstruate, monthly cycles often bring discomfort and disruption. Health conditions such as polycystic ovary syndrome (PCOS), diabetes, and heart disease can further interfere with hormonal balance and menstrual regularity. Now, researchers have identified another factor that can disrupt the menstrual cycle: Long COVID.

A new study strongly associates Long COVID with increased menstrual flow, longer duration, missed periods, and unexpected bleeding between cycles. These findings shed light on how the virus continues to affect health beyond initial infection and may guide future treatment for irregular menstruation.

Imagine waking up with the flu one morning, calling out sick, and spending time resting and recovering. A week passes, and symptoms linger. Then two or three weeks slip by, and still no relief. Now picture over 100 weeks passing with the same unrelenting illness.

One man experienced this with COVID-19, worsened by his suppressed immune system. He endured acute symptoms for more than 750 days. Throughout this time, he visited the hospital five times because of his constant respiratory struggles.

Unlike in Mary Shelley’s Frankenstein, electricity cannot reanimate dead bodies. Yet new research shows the fictional idea isn’t far off. Electrical stimulation may boost the body’s natural healing processes.

Researchers at Trinity College Dublin found that electrical stimulation can reboot macrophages. These white blood cells either move through tissues or reside within them. At injury sites, they reduce inflammation and accelerate healing. The findings could lead to breakthroughs in treating injuries and disease.

Autumn brings many things: cooler weather, pumpkin carving, and longer walks outside. Yet the season also carries a downside—rising rates of respiratory illness.

The Nimbus variant of COVID-19 was uncovered in the summer of 2025. Now, as fall begins, another newly identified variant has appeared: Stratus, more formally known as XFG. Stratus is a recombinant virus, formed from two variants, LF.7 and LP.8.1.2. It first emerged in Canada but has since spread worldwide.

For as long as mosquitoes have been biting humans, one question has persisted: what makes certain people so tasty? Is it bananas, garlic, clothing color, or blood type?

Most of these common beliefs have no evidence behind them. But a recent field experiment may finally offer some real clarity. Researchers found that certain hedonistic habits made people more attractive to mosquitoes—specifically beer drinking, sleeping with partners, and skipping sunscreen.
