It has been claimed that because most of our DNA is active, it must be important, but now human-plant hybrid cells have been used to show this activity is mostly random noise

A joint research team from South Korea has developed a fascinating wheel inspired by origami and Da Vinci bridge principles that could unlock access to the Moon’s most dangerous and scientifically useful terrain. The wheel expands from 230 mm to 500 mm in diameter on demand, allowing small rovers to navigate steep lunar pits and lava tube entrances that would trap conventional vehicles.

Astronomers using the Hubble Space Telescope have discovered the largest planet forming disk ever observed around a young star, stretching nearly 40 times the diameter of our Solar System. Nicknamed “Dracula’s Chivito” for its hamburger like appearance when viewed edge on, this massive disk reveals an unexpectedly chaotic and asymmetric structure with wisps of material extending far above and below its central plane. The discovery offers an unprecedented window into how planets might form in extreme environments, challenging previous assumptions about the orderly nature of planetary nurseries.

Three start-ups are aiming to create gene-edited babies. Columnist Michael Le Page has no doubt that editing our offspring will one day become routine, but not like this

Yesterday the Sun reached its southernmost point in planet Earth's sky.

At the end of their lives, most satellites fall to their death. Many of the smaller ones, including most of those going up as part of the “mega-constellations” currently under construction, are intended to burn up in the atmosphere. This Design for Demise (D4D) principle has unintended consequences, according to a paper by Antoinette Ott and Christophe Bonnal, both of whom work for MaiaSpace, a company designing reusable launch vehicles for the small satellite market.

Launched in March, NASA’s SPHEREx space telescope has completed its first infrared map of the entire sky in 102 colors. This map will enable 3D distance measurements to other galaxies and allow astronomers to measure the influence of Cosmic Inflation on the large-scale structure of the Universe.

Can you tell that today is a solstice by the tilt of the Earth?

Sleep is often the first thing that many people associate with rest, but humans also require restorative downtime when awake

Solar sails have some major advantages over traditional propulsion methods - most notably they don’t use any propellant. But, how exactly do they turn? In traditional sailing, a ship’s captain can simply adjust the angle of the sail itself to catch the wind at a different angle. But they also have the added advantage of a rudder, which doesn’t work when sailing on light. This has been a long-standing challenge, but a new paper available in pre-print from arXiv, by Gulzhan Aldan and Igor Bargatin at the University of Pennsylvania describes a new technique to turn solar sails - kirigami.

Somewhere at the edge of mathematics lurks a number so large that it breaks the very foundations of our understanding - and in 2025 we came a step closer to finding it

Tiny ball bearings surround a larger central bearing during the Fluid Particles experiment, conducted inside the Microgravity Science Glovebox (MSG) aboard the International Space Station’s Destiny laboratory module.

In this Oct. 20, 2025, photo, tiny ball bearings surround a larger central bearing during the Fluid Particles experiment, conducted inside the Microgravity Science Glovebox (MSG) aboard the International Space Station’s Destiny laboratory module. A bulk container installed in the MSG, filled with viscous fluid and embedded particles, is subjected to oscillating frequencies to observe how the particles cluster and form larger structures in microgravity. Insights from this research may advance fire suppression, lunar dust mitigation, and plant growth in space. On Earth, the findings could inform our understanding of pollen dispersion, algae blooms, plastic pollution, and sea salt transport during storms.

In addition to uncovering potential benefits on Earth, research done aboard the space station helps inform long-duration missions like Artemis and future human expeditions to Mars.
