Could Mars soil block Earth microbes? ‘Water bears’ offer a clue

Tardigrades, commonly known as water bears, may be better suited by a new name: Tardiguardians of the Galaxy. Unlike the fictional ragtag team of unenthusiastic heroes, the microscopic animals are providing real insight into how humans could adapt extraterrestrial resources to support space exploration, as well as whether such resources could help protect against the […]

Metasurface-based SLM could enhance AR, VR and LiDAR performance

Many cutting-edge technologies, ranging from augmented reality (AR) and virtual reality (VR) to LiDAR (light detection and ranging) systems, rely on components that enable the precise control of light. These components include so-called spatial light modulators (SLMs), systems that dynamically adjust the position of a light wave within its cycle (i.e., phase), as well as […]

Video: 3 Mich. officers injured in pursuit of suspect who led police through landfill

Huron Township officers picked up a pursuit of a woman, believed to be armed, who called in threats to 911, tried to run over officers and ram cruisers, and fled into a landfill

Image: First glimpse of comet 3I/ATLAS from Juice science camera

This striking image from the science camera on ESA’s Jupiter Icy Moons Explorer (Juice) shows interstellar comet 3I/ATLAS spewing dust and gas. The tiny nucleus of the comet (not visible) is surrounded by a bright halo of gas known as the coma. A long tail stretches away from the comet, and we see hints of […]

3D-printed spring deploys on small commercial spacecraft

With a simple motion, a jack-in-the-box-like spring designed at NASA’s Jet Propulsion Laboratory showed the potential of additive manufacturing, also known as 3D printing, to cut costs and complexity for futuristic space antennas. Called JPL Additive Compliant Canister (JACC), the spring deployed on the small commercial spacecraft Proteus Space’s Mercury One on Feb. 3, 2026. […]

Video: Landsat 9: More than just a picture

For over 50 years, the Landsat program has provided the longest continuous satellite record of Earth’s land surface from space. Landsat 9, launched in 2021, is the latest mission in this remarkable legacy—building on decades of Earth observation with upgraded technology, including enhanced radiometric resolution, improved signal-to-noise performance, and polar night thermal imaging.

A study in stardust: Massive binary stars emit tiny carbon particles

Yale junior Donglin Wu leads a new study showing that some of the biggest stars in the universe shed some of the smallest dust particles. It’s fitting that Wu’s first major scientific journal article as lead author focuses on stardust—tiny solid grains that form from stellar winds, drift into interstellar space, and may eventually become […]

Beam-spin asymmetry study puts proton models to the test

Getting an up-close view of life at the cellular level can be as simple as placing onion skin under a microscope and adjusting the knobs. Peering deeper, into the heart of the atoms within, isn’t as easy. It requires peeling through layers of particle accelerator data to shed light on protons, neutrons and the subatomic […]

Was Achilles a real person

When we hear the name Achilles, we think of a great Greek hero from mythology who fought in the Trojan War. Achilles was known for his strength and bravery on the battlefield. He was also known for his tragic flaw, which led to his downfall. When we turn the pages of history, we also […]

The screech of peeling sticky tape conceals a rapid train of tiny shockwaves, ultrafast imaging shows

A new experiment has uncovered the mechanism responsible for the screeching sound made by peeling sticky tape. Using a combination of ultrafast imaging and synchronized acoustic recordings, Sigurdur Thoroddsen and colleagues at King Abdullah University of Science and Technology have shown that the noise is produced by a rapid train of tiny shockwaves, released through […]

Matching vibrations is all it takes to shut down superconductivity in a nearby crystal

The world is never really at rest. Even in a vacuum near ultracold temperatures where all classical motion should come to a halt, you’ll find quantum fluctuations. In thin, two-dimensional materials, these include random vibrations that can alter electromagnetic fields, a feature that theorists have posited could be quite useful for modifying materials.

Planet Nibiru

A solar system is a mystery, and scientists have been trying to unravel its hidden secrets for centuries. There are various theories and hypotheses about the solar system, but the one that has gained the most traction in recent years is the Planet Nibiru theory.

The outer solar system is the region of the […]

What does it mean to compute? Framework maps hidden computations running inside natural dynamic systems

Some computers are easy to spot. Artificial, human-built computers like those found in smartphones and laptops are abstract dynamic systems with observable computational elements like input, output, energy cost, and logical processes. Other computers aren’t so readily recognized.
