How a shape-shifting tiny rover inspired by Japanese toys autonomously explored the moon

Moon missions come in all shapes and sizes, from car-sized rovers packed with scientific equipment to towering rocket payloads—and now, a small, shape-shifting machine that is about the size of the average palm.

Binary asteroids’ puzzling configurations may link to multi-satellite history

Binary asteroid systems are widespread throughout our inner solar system. For decades, the standard paradigm held that many of them form when a rapidly spinning primary asteroid casts off material, which then reaccumulates into an elongated moon orbiting near the Roche limit.

Consciousness likely not unique to earthlings, paper says

Does consciousness depend on flesh and blood? The answer is almost certainly no, according to Eric Schwitzgebel, a distinguished professor of philosophy at the University of California, Riverside. In a new working paper, Schwitzgebel and Jeremy Pober, a former UCR graduate student who is now a postdoctoral researcher at the University of Lisbon, assert that […]

On the hunt for cosmic dawn and the universe’s very first stars

After only four short years, NASA’s James Webb Space Telescope (JWST) and observational cosmologists like Richard Ellis at University College London (UCL) have pushed the cosmic lookback time to an era when the universe’s very first stars and galaxies are within observational reach.

Electron matter waves gain ultrafast torque that flips handedness in femtoseconds

Many natural processes, ranging from magnetism to chemical reactions, entail the movement and rotation of particles at very small scales. In quantum mechanics, particles exhibit both particle-like and wave-like behaviors, and their states can be described mathematically using representations known as wavefunctions.

New art test could help museums spot fake Van Goghs without touching paintings

A new study published in the peer-reviewed journal Surface Topography: Metrology and Properties introduces a pioneering, noninvasive technique that can distinguish authentic artworks from forgeries, offering museums, collectors, and auction houses a major advantage in tackling art fraud.

NASA’s CloudCube pioneers miniaturized radar to study clouds, precipitation

A compact, multifrequency radar built by a team at NASA’s Jet Propulsion Laboratory will make it easier to collect information about dynamic cloud systems. Called CloudCube, this new instrument simultaneously probes the atmosphere with three radar signals, spanning 36 to 240 GHz, for optimized sensitivity to a wide range of water droplet and ice particle […]

Cosmic acceleration holds up as new analysis rebuts slowdown claim

Our universe’s expansion is still accelerating despite recent claims suggesting otherwise, an international team of astrophysicists says.

Lab-created ‘moon’ rock could help scientists interpret lunar data and explore how water might form on the moon

The moon may look unchanged from afar, but its surface is constantly reshaped by microscopic impacts and a steady stream of particles from the sun, a process known as space weathering. Now, Georgia Tech researchers have recreated one of those weathering sources, solar wind, in the lab—offering new insight into how the lunar surface evolves. […]

AI helps reveal large-scale quantum effects hidden in stacked atomic sheets

Quantum materials are a class of exotic materials with special properties that are governed by quantum mechanics rather than classical physics. Those properties—like superconductivity, entanglement and unusual forms of magnetism—often originate in the tiny repeating patterns of atoms inside crystals, but through clever engineering, they can be observed and controlled at a more human scale.

Open-source FLIM Playground could speed reproducible analysis of complex cell images

Modern fluorescence microscopy can generate images of living cells as stunning to look at as they are informative to study. For techniques like fluorescence lifetime imaging microscopy (FLIM), those images provide a window into cell metabolism, helping scientists study cancer treatment, autoimmune disease and more.

The Milky Way was rewired by a cataclysmic collision billions of years ago. Now it is on course for another

No matter the time or vantage point, from a pre-Neolithic cave to a post-lockdown London high-rise, the predictability of the night sky has always been humanity’s symbol of permanence and reassuring stability.
