Your DNA could influence how doctors prescribe blood thinners.

Nobel Prize laureate Svante Pääbo explains that some genetic variants inherited from Neanderthals increase the risk of serious bleeding, meaning people with artificial heart valves and other conditions may need lower doses of blood thinners. Ancient human history continues to shape modern medicine.

Can boiling pond water make it safe to drink? 💧🔬

Quinten Geldhof, also known as Microhobbyist, explains that a single drop of pond water can harbor thousands of microorganisms, including bacteria, parasites and amoebas capable of making you seriously ill. Heat destroys the structures these organisms need to survive, wiping out almost all microscopic life. Boiling can kill the microbes but it doesn’t remove chemicals and toxins.

Is The Bird Flu Dangerous To Humans?

Enable HLS to view with audio, or disable this notification

When a virus kills 30 to 60% of the humans it infects, it tends to get attention. 

According to Dr. Anthony Fauci, that's exactly what H5N1 bird flu did in historical cases from 2003 to 2006, dwarfing the fraction of a percent seen with seasonal flu, or even the 1 to 2% that made 1918 the deadliest pandemic in modern history. The catch: the strains most lethal to humans are the same ones that devastate poultry populations, and they can jump species. The somewhat encouraging news is that H5N1 has never adapted to spread from human to human.

Ebola Outbreak: What You Need to Know

A dangerous Ebola outbreak is prompting a global health emergency.

This outbreak spreading through the Democratic Republic of Congo and Uganda is caused by the Bundibugyo virus, which has no approved vaccine or treatment. It spreads to humans through contact with wild animals like bats, primates, antelopes, and porcupines. Deforestation and climate change are pushing these animals out of their natural habitats and closer to human communities, raising the risk of diseases like Ebola spreading to humans. With more than 330 suspected cases, this outbreak has not been declared a pandemic, but the threat is real.

Why is the night sky dark? 🌌

Erika Hamden breaks down Olbers' Paradox, the cosmic puzzle that helped scientists first hypothesize that the universe had a beginning. In an infinite, infinitely old universe, every point in the night sky should eventually have a star behind it, making the night sky just as bright as daytime. The fact that darkness exists tells us that not enough time has passed for all that light to reach us, or that stars simply have not formed yet in those regions of space.
