What Happens When COVID-19 Persists Beyond Two Full Years

March 11, 2026 by Logan Hamilton Leave a Comment

Some patients are experiencing long COVID for years.

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.

Electrical Stimulation Shows Promising Results For Boosting Healing Processes

March 9, 2026 by Logan Hamilton Leave a Comment

Electrical stimulation may be key to helping the healing process.

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.

New Stratus Variant Of COVID-19: Spread, Symptoms, & Impact

March 4, 2026 by Logan Hamilton Leave a Comment

A new COVID variant could have some serious implications.

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.

Why Do Mosquitoes Bite Some People More? Myths Busted

March 2, 2026 by Logan Hamilton Leave a Comment

We are getting a better understanding of who, and why, mosquitoes bite.

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.

Inhaled Heparin is a Promising New COVID-19 Treatment

February 25, 2026 by Logan Hamilton Leave a Comment

Inhaled heparin may be key to solving COVID problems.

COVID-19 cases are stable or declining across most U.S. states. The CDC reports 36 states show declining or likely declining infections. Only one state shows growth, while 10 states remain unchanged. In some U.S. states and territories, the data is still inconclusive.

Even with cases dropping, new COVID-19 treatments remain essential. Future surges or infectious new variants could still emerge. Researchers are actively seeking therapies to lower risks for patients.

A study from King’s College London tested inhaled heparin. Results showed lower risk of severe complications and reduced need for ventilation. The drug also showed promise for other respiratory infections
