A strange quantum rule caps electrical resistance
Physicists have uncovered a surprising limit to electrical resistance caused by particles colliding. Using ultracold potassium atoms trapped in a grid of light, researchers created a highly controlled stand-in for electrons moving through a solid. As collisions became more frequent and intense, resistance initially rose, but eventually hit a ceiling and stopped increasing.

Strange gamma rays could reveal how stars forge heavy elements
Scientists traced a mysterious surge of low-energy gamma rays from zinc-70 to magnetic changes occurring inside its nucleus. The breakthrough could improve models of how stars, supernovae, and neutron star mergers create heavy elements.

Tiny black holes may be secretly exploding stars across the Milky Way
Primordial black holes may occasionally pass through white dwarf stars and trigger enormous Type Ia supernova explosions. Researchers found that these events could explain chemical patterns seen in supernova remnants, nearby explosions, and stars across the Milky Way.

Scientists left water inside a battery and nearly doubled its power
A surprisingly simple change could make sodium-ion batteries far more powerful while opening the door to turning seawater into drinking water. Researchers at the University of Surrey found that sodium vanadium oxide performs much better when its naturally occurring water is left inside instead of being removed during manufacturing.

New process turns plastic waste into hydrogen fuel while trapping the carbon
A new chemical process can transform three of the most common plastics into high-purity hydrogen without sorting them first. The technique operates at much lower temperatures than traditional gasification and captures most of the plastic’s carbon in solid or liquid forms instead of releasing it as carbon dioxide.

Black holes may spit out nearly as much matter as they swallow
A black hole observed during a dramatic 2023 eruption did not simply devour gas from its nearby companion star. It also expelled large amounts of material through powerful jets and winds, even after the outburst had nearly faded. The results suggest black holes may continue reshaping their surroundings long after their brightest fireworks end.

AI can tell if your brain is aging faster than you are
A person’s sleeping brain may reveal warning signs of dementia long before memory problems begin. Researchers used machine learning to analyze EEG recordings from about 7,000 adults and found that an older-than-expected “brain age” was tied to a sharply higher dementia risk. Every additional 10 years of brain aging raised that risk by nearly 40%.

This new alloy is up to 10 times stronger than steel and surprisingly flexible
Engineers have transformed a notoriously brittle cobalt-aluminum compound into a material that is both extremely strong and capable of bending without breaking. Their nanoscale design produced a yield strength about six to 10 times greater than high-strength structural steel while sustaining substantial deformation at room temperature. The approach could enable tougher turbine blades and higher-performance engines.

Mysterious Milky Way object accelerates protons beyond one quadrillion electron volts
Scientists have identified LHAASO J1912+1014u as a cosmic accelerator that can push protons beyond one quadrillion electron volts. The finding may help reveal where the Milky Way’s most energetic cosmic rays come from and how they influence the galaxy.

NASA’s Curiosity rover finds a mysterious honeycomb landscape on Mars
NASA’s Curiosity rover has entered a Martian valley covered by an astonishing “sea” of tiny polygon-shaped fractures. The honeycomb patterns, each only a few inches wide, stretch across the landscape and even wrap around a nearby 20-foot-tall butte.

World-first photonic time crystal opens a new era of light control
Scientists have built the first all-optical photonic time crystal, allowing them to reshape the behavior of terahertz light at extraordinary speeds. The breakthrough could open the door to ultrafast computing, smarter communication systems, advanced imaging, and a new generation of highly tunable lasers.

Mathematicians prove perfectly fair elections are impossible
Mathematicians have shown that no electoral system can perfectly balance local representation, proportional national results, and a fixed-size parliament once enough parties compete. A newly proposed voting method could soften these unavoidable trade-offs and produce outcomes that are much closer to fair.

Scientists twist crystal layers and reshape matter from within
Researchers have found a way to build much larger “twisted” oxide materials while precisely controlling how their atomic layers line up. Because these materials can be made over large areas and transferred onto different surfaces, the technique could help turn twistronics from a laboratory curiosity into a practical platform for next-generation electronics.

Giant waves are sweeping Mars’ atmosphere into space
The solar wind may be stripping away Mars’ atmosphere by creating giant rolling waves along its outer edge. Data from MAVEN and Tianwen-1 show that these waves form plasma clouds that carry atmospheric particles into space. The process is concentrated on one side of Mars and may have played a major role in drying out the once potentially habitable planet.

Moonquakes could reveal hidden water beneath the lunar surface
Hidden moon ice may reveal itself through the way it bends and reflects vibrations from moonquakes. The technique could help astronauts locate vital water supplies and uncover clues about the origins of Earth’s oceans.

Scientists just 3D printed one of the hardest metals on Earth
A new 3D printing technique can produce exceptionally hard tungsten carbide cobalt while using less of its expensive raw materials. By softening rather than fully melting the material, researchers created defect-free samples with industrial-grade hardness and opened the door to more efficient manufacturing.

Dark matter’s secret force does the opposite of what scientists expected
Dark matter particles may exert a hidden force on one another, but its effects are stranger than expected. An extra attraction helps the particles cluster, yet it also makes dark matter effectively lighter as the Universe expands. That weakens its gravitational impact and usually slows the growth of cosmic structure rather than accelerating it.
