Recent science shows that a simple gas—hydrogen—is more than just a building block of water. Because it is so small, the molecule can slip through cell walls and even the blood‑brain barrier, reaching places that many medicines cannot. Researchers have tested hydrogen in a variety of ways: breathing
The Russian president signed a new order that reshapes how animal vaccines are made after a cattle outbreak caused thousands of deaths in Siberia. The event led to protests and demands that top officials step down, a rare reaction in wartime Russia. The decree combines several state‑owned firm
Parkinson’s disease slowly changes how the brain works. It starts when tiny cells that make dopamine begin to disappear. Dopamine is a key messenger in the brain that helps control movement. Without enough of it, people often feel stiff, move slowly, and shake when resting. These problems grow worse
A 24‑year‑old former college basketball star from Louisville began feeling short of breath one November. Doctors first thought she had pleurisy, an inflammation of the lung lining, and gave her anti‑inflammatory pills. Her condition worsened; she sweated heavily at night, couldn’t lie flat without s
Alopecia areata is a long‑term autoimmune condition that causes hair to fall out without scarring. The problem starts when the immune system attacks growing hair follicles, called anagen follicles. Scientists have discovered that Janus kinase (JAK) inhibitors can stop this harmful signaling, givi
The new study shows that when temperatures drop, heart‑related deaths rise sharply across the United States. Researchers looked at data from 2000 to 2020 in 819 counties, covering about 80 % of adults over 25. They found that the safest temperature for heart health is around 23 °C (74 °F). When temp
The experiment began with a curious question: how do tiny mosquitoes spot us? A professor and a college student tried to answer it by putting the student in a room full of insects. The first attempt used a mesh suit, but it didn’t stop the mosquitoes from biting. After many painful stings, the team
The number of young women dying from high blood pressure has more than quadrupled over the last twenty years, a new study shows. In 2023, nearly five women out of every hundred thousand in the 25‑to‑44 age group lost their lives to heart disease caused by high blood pressure, compared with just one
Alcohol can damage the liver in many ways, from fat buildup to serious cancer. People with heavy drinking habits often develop a chain of liver issues that can become life‑threatening. One dangerous form is alcohol‑related hepatitis, which can kill quickly if not treated fast. The disease usu
The link between flu infections and heart problems is clearer now. Doctors once saw more heart attacks during cold seasons but didn’t know why. Recent studies explain the connection. Flu can trigger serious heart events, especially in people with existing heart disease. About half of adults hospita
