What does it take to do a spacewalk? Skill, courage, and being able to wear a men's size medium.

On June 25, astronauts Shane Kimbrough and Thomas Pesquet successfully completed an almost seven-hour EVA (extravehicular activity, or spacewalk) to install solar panels on the International Space Station. What does it take to don a spacesuit and venture ...

Hubble trouble is latest glitch in space telescope's long and storied history

For the past month, our most beloved eye on the universe has been closed, blinded by a computer glitch that NASA experts are still working to solve. After 31 years in space, the Hubble Space Telescope unexpectedly shut down on June 13 after suffering a ...

On June 7, Juno zoomed within just 645 miles (1,038 kilometers) of Ganymede, the largest moon in the solar system. It was the closest a probe had gotten to the icy, heavily cratered world since May 2000, when NASA's Galileo spacecraft flew by at a distance of ...

City-sized asteroids smacked ancient Earth 10 times more often than thought

Asteroids the size of cities, like the one that wiped out the dinosaurs, slammed into the ancient Earth way more often than previously thought, a new study has found. Approximately every 15 million years, our evolving planet would get a hit by a piece of rock ...

A human apolipoprotein L with detergent-like activity kills intracellular pathogens

Most human cells, not just those belonging to the immune system, mount protective responses to infection when activated by the immune cytokine interferon-gamma (IFN-γ). How IFN-γ confers this function in nonimmune cells and tissues is poorly understood.

Optical levitation of glass nanosphere enables quantum control

Researchers at ETH Zurich have trapped a tiny sphere measuring a hundred nanometres using laser light and slowed down its motion to the lowest quantum mechanical state. This technique could help researchers to study quantum effects in macroscopic ...

Researchers unveil 'phenomenal' new AI for predicting protein structures

To function, these long chains of amino acids twist and fold and intertwine into complex shapes that can be slow, even impossible, to decipher. Scientists have dreamed of simply predicting a protein's shape from its amino acid sequence—an ability that would ...
