Scientists once saw mitochondria—the powerhouses inside our cells—as fixed residents with one job: producing energy. Now they know these tiny structures are more like delivery trucks zipping between cells, dropping off supplies or picking up garbage. This movement happens with help from three main h
The U. S. government just revised the rulebook for the committee that shapes vaccine recommendations for the country. The group, usually made up of doctors and scientists, now welcomes voices from toxicology and data analysis to weigh in on vaccine safety. Critics say this mix of expertise could dil
When the Orion spacecraft returns to Earth during Artemis II, it will face its biggest challenge yet. Traveling at speeds faster than a bullet, the capsule will hit temperatures hot enough to melt steel. This extreme heat is what makes the heat shield so critical - it's the only thing standing betwe
Space travel isn’t just about rockets and moon landings—it’s also a giant science experiment. NASA’s Artemis II mission sent four astronauts on a test flight around the Moon, but hidden among them were four tiny lab tools no bigger than USB drives. These aren’t ordinary gadgets; they’re organ chips
Ottawa just became the latest city to stop shops from selling kratom, a plant that comes from Southeast Asia.

India joins many countries in celebrating dental professionals, but it chose a different date. Instead of March 6 like the U. S. , India picked December 24 in 2016. That day marks the birth of Dr. Rafiuddin Ahmed, who helped shape modern dentistry in the country. Yet, some clinics and media still fo
During a heated online exchange, a world leader hinted at serious consequences if rivals refused to back down. His words suggested dramatic action against critical systems that keep a country running. Critics quickly labeled the statement reckless and dangerous, comparing it to some of history’s wor
The African swine fever virus is a tough survivor, especially in cold or dirty water. Scientists tested how long it can stay active in different water conditions. They found that in natural water, the virus lasted at least 42 days at temperatures of 4°C, 15°C, and 25°C. In very clean water, it survi
For years, central banks kept interest rates unusually low to help economies recover after tough times. The idea was simple: cheaper loans would encourage spending and investment, pushing growth forward. But something unexpected happened along the way. Instead of just helping struggling businesses,
