The Japanese probe Hayabusa collected samples from the asteroid Itokawa and returned them to Earth in 2010. Now researchers from Arizona State University have discovered traces of water in those samples, adding weight to the idea that much of Earth’s water may have come from asteroid impacts.

Scientists have discovered a tiny fragment of a comet in a meteorite. The bulk of the rock itself was once an asteroid, but when the team cracked it open and analyzed the inside, they found that the growing asteroid must have swept up the seed of a comet billions of years ago.

​​Scientiists continue to uncover new connections between the gut microbiome and human health. Another example of this are the emerging ties between gut health and autism, with an exciting new study demonstrating how fecal transplants can dramatically reduce its symptoms in the long term. ​

​NASA’s Curiosity rover and its suite of advanced tools have revealed all kinds of fascinating facts about Mars, but scientists here on Earth have now uncovered a surprising characteristic through one of its more rudimentary instruments, an accelerometer similar to what you'd find in a smartphone.

​If you need to close up an injury or incision in human body tissue, you use sutures, staples or a surgical adhesive … right? Well, if technology that's currently being developed at Arizona State University gets commercialized, liquid silk combined with gold may eventually be a better way to go.

The majority of stars in our Milky Way aren’t Sun-like – they’re the smaller and cooler red dwarfs. To determine how well these stars might be able to support life, A NASA program is using Hubble to monitor their flare activity, and the first results don’t paint a positive picture.

​For centuries, various cultures have used clay as a remedy for infections. Now, scientists from Arizona State University (ASU) and the Mayo Clinic have determined that blue clay in particular may indeed be effective at treating infected wounds.

A new study on the density of the seven planets in the nearby TRAPPIST-1 system has found that these worlds may have even more water than Earth does – but in a cruel case of having too much of a good thing, that might be enough to drown out any hopes of finding life there.

To look through space is to look through time. Astronomers have now peered right back to the “Cosmic Dawn” – when the first stars were beginning to fire up – by picking up an extremely faint radio signal that marks the earliest evidence of hydrogen, just 180 million years after the Big Bang.

Anti-aging research has long focused on DNA structures known as telomeres, which have been directly linked to cell longevity. Now scientists have discovered a new way to potentially supercharge the mechanism, which may help keep this “molecular clock” – and ourselves – running better for longer.

A pair of independent studies from two teams used CRISPR technology​ to genetically alter ants to remove their ability to "smell," which resulted in their inability to interact with normal ants and produced changes in their brains.

​As far as many people are concerned, there are just two ways of exploring other planets – either robots do it while all the humans stay back on Earth, or astronauts go and do so in person. According to a trio of scientists, however, the best idea may lie somewhere between the two.
