The first generation of stars in the universe could have produced significant amounts of water upon their deaths, just 100 million to 200 million years after the Big Bang. Signatures of water have previously been observed some 780 million years after the Big Bang. But now, computer simulations suggest that this essential condition for life…
After brain surgery, Jon Nelson and other volunteers are tasked with rehabbing their brain. This job is harder than it might seem, as people re-learn how to navigate the world with a range of emotions that they haven’t felt in a long time.

Venus is not an obvious place to look for life. Its globe-spanning cloud decks are made…
Even as Texas grapples with a measles outbreak that has already left one child dead, the childhood vaccination schedule is coming under new scrutiny by the Trump administration. The recommended list of immunizations starting at birth protects kids against more than a dozen deadly diseases from measles to whooping cough. U.S. Health and Human Services…
Imagine seeing cake in a virtual world, then tasting it. Researchers have taken a step toward that reality with a device that delivers virtual tastes by squirting chemicals onto the tongue. The system, called “e-Taste,” can detect chemicals in foodstuffs and wirelessly transmit this information to a device that delivers the same or equivalent chemicals…
Alpha Centauri, the nearest star system to the sun, is probably shedding comets and asteroids into our solar system — and even producing a few meteors in our sky. Located just 4.3 light-years from Earth, Alpha Centauri consists of three stars that revolve around one another. If Alpha Centauri has an Oort cloud of distant…
