NASA’s Curiosity rover has discovered opal on Mars. The deposits may prove to be valuable to future Martian explorers not as jewelry but as a potential source of water.

Researchers have developed a new open-source program that can convert drawings or digital models into nanoscale sculptures made of DNA. In tests, the system nailed rounded objects like vases and bowls.

A team experimenting with Parkinson's disease treatments has demonstrated how implanting carefully cultivated stem cells into rats can bring about remarkable recovery from motor symptoms typical of the disease.

A bizarre object named ‘Oumuamua, defying classification, was the first interstellar object ever discovered. Now a newly proposed origin story neatly explains all of its observed oddities – it may be a piece of nitrogen ice from an “exo-Pluto.”

Newts do it. Lizards do it. Even educated axolotls do it. Regenerating limbs isn’t something many animals can do, but now there’s a surprising new addition to the list – alligators. A study has shown that alligators can regrow part of a lost tail.

Perhaps on other planets, diamonds are as common and boring as rocks. Astronomers suggest that some planets might actually be largely made of diamonds, and now a team has calculated how such a planet could form and how it would be structured.

What kind of threat can tiny plastic fragments pose to the health of living organisms? Scientists have turned to human tissue for answers, and discovered evidence of plastic fragments in every single sample they studied.

In some ways, the most Earth-like world in our solar system is Saturn’s largest moon, Titan. And now, astronomers from NASA JPL and Arizona State University have used years of Cassini data to construct the first global map of Titan.

A photographic search by NASA's Lunar Reconnaissance Orbiter (LRO) has discovered the crash site of the Israeli Beresheet moon lander. By making a series of comparison images, the hunt confirmed the area where the privately operated unmanned spacecraft impacted the lunar surface on April 11, 2019.

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. ​
