A low-cost anti-inflammatory drug appears to reduce the risk of death in patients with COVID-19. The promising result comes from a large study of therapies being conducted in the U.K.
Emergency use authorization makes it easier for doctors to use a drug in a manner not specifically approved by the Food and Drug Administration. The FDA granted these drugs this status in March.
The race is on. What will it take to develop, test and distribute a safe and effective vaccine?
Getting DNA into plant cells is tricky. Researchers have tried using infectious bacteria, as well as gene guns that shoot gold bullets. Then a physicist came up with a new approach almost by accident.
NASA’s six-wheeled rover landed on the red planet in January 2004 for what was billed as a 90-day mission. The plucky robot was still going until a dust storm on Mars last summer killed it.
A lot of vaccines and some medications need to be delivered by injection. Two groups of researchers are designing ways of delivering these medications by putting them in pill form.
Astronomers have found a distant dwarf planet that appears to confirm the existence of Planet Nine, a giant planet lurking in the outer reaches of the solar system.
New options for non-addictive pain treatment are sorely needed. One researcher is borrowing from the field of cancer nanomedicine to test an idea that could bring relief to chronic pain sufferers.
Astronomers have found 12 more moons orbiting the planet Jupiter. These moons are all small — just 5 kilometers or less across — and one of them behaves very strangely.
Engineers in California are working on a new test that could offer a fast, cheap way to see if people are infected with the parasite.
Researchers have evidence supporting the existence of plumes of water shooting up from the interior of Jupiter’s icy moon Europa.
The NASA mission is set to launch Saturday morning. The InSight spacecraft will land in the Elysium Planitia to listen for “Marsquakes” and learn more about what Mars is made of.
NASA is building a new space-based laser communication that will allow live, high-definition video from Mars and beyond — something that’s not possible with standard radio equipment.
Hawking was a theoretical physicist who changed how scientists think about gravity. He also wrote the best-selling book A Brief History of Time and lent his machine-aided voice to TV shows. He was 76.
