Astronauts Chris Williams of NASA and Sophie Adenot of the European Space Agency work together in the Kibo laboratory module’s Life Science Glovebox, processing genetic-material samples for the DNA Nano Therapeutics‑3 experiment. The investigation is exploring DNA‑inspired assembly techniques as a way to manufacture treatments—such as chemotherapy and immunotherapy—that can kill cancer cells and activate the immune system.

Rotating detonation rocket engines work differently than traditional rockets to maximize thrust while using less fuel—an advantage that could help spacecraft explore farther in the solar system

NASA and other space agencies spend a lot of time and money considering the cleanliness of their missions. Billions of dollars are spent in and on cleanrooms every year, with the express effort of ensuring both that the equipment operates without interference, but also that we don’t accidentally contaminate our exploration target with life from Earth itself. So far, we have primarily focused on bacteria in our efforts to stop this contamination, but according to a new paper by Atul M. Chander of NASA Jet Propulsion Laboratory and his co-authors, we might be missing an entirely different threat - fungi.

Robots can now run a half-marathon faster than humans and are rapidly homing in on the men's 100-metre sprint record. But why are companies so keen to create speedy robots that have no obvious application in homes or factories?

A condition that affects 10 to 15 percent of women may affect men, too. But many doctors don’t know about it

The ongoing closure of the Strait of Hormuz has seen energy prices soar, but Alice Klein pays just A$25 (£13) a month for her electricity, even when charging an electric car or running an air conditioner.

Using nothing but a laser beam, scientists at Texas A&M University have demonstrated that tiny engineered devices can be lifted and steered in three dimensions without any physical contact. This breakthrough could one day form the basis of a propulsion system capable of reaching our nearest neighbouring stars in decades rather than centuries.

Researchers at the Institute of Science Tokyo have developed an origami inspired foldable antenna for CubeSat satellites that weighs just 64 grams yet in orbit, it deploys to two and a half times its stowed size. The antenna folds away neatly for launch and deploys automatically in space, achieving high gain communications performance from a package small enough to fit in your pocket and could one day support missions as far away as the Moon.

A revolutionary cancer treatment is now being applied to a wide range of autoimmune disorders. Columnist Michael Le Page finds it is proving to be even more effective than expected

Direct attacks, oil spills and the threat of nuclear waste are putting the Gulf region’s desalination plants at risk—here’s why that matters

Space travel has taught us valuable lessons for living and working in outer space, specifically regarding how microgravity (often mistakenly called zero-gravity) impacts the human body during short- and long-term spaceflight. This includes decreased muscle and bone mass, fluid shifts, reduced heart rate, psychological health, compromised immune system, and radiation exposure. But with agencies like NASA aspiring to build a lunar base and establish a long-term presence on the Moon, and eventually Mars, how could space travel impact potentially having babies in space?

Why are there three arches across the sky instead of two?

A sub-two-hour marathon has long been seen as a tantalizing benchmark for elite runners—and shoemakers have been in a race to design footwear that can help them get there
