A team at the University of Stuttgart has engineered a compact short-pulse laser that achieves up to 80% efficiency—far surpassing current models. Their new multipass design reuses light within a small crystal, combining power and precision in a palm-sized system. It opens the door to portable, cost-effective lasers for medicine, analytics, and quantum science.

Researchers are using black hole shadows to challenge Einstein’s theory of relativity. With new simulations and future ultra-sharp telescope images, they may uncover signs that his famous equations don’t tell the whole story.

MIT scientists uncovered direct evidence of unconventional superconductivity in magic-angle graphene by observing a distinctive V-shaped energy gap. The discovery hints that electron pairing in this material may arise from strong electronic interactions instead of lattice vibrations.

A colossal black hole 10 billion light-years away has been caught devouring one of the universe’s biggest stars, unleashing a flare 30 times brighter than any seen before. The flare, detected by Caltech’s ZTF, likely marks a tidal disruption event — when a star is shredded by a black hole’s gravity.

Using CERN’s Super Proton Synchrotron, researchers generated plasma fireballs to simulate blazar jets. The beams stayed stable, suggesting plasma instabilities aren’t responsible for missing gamma rays. Instead, the data strengthens the idea of ancient intergalactic magnetic fields, possibly from the Universe’s earliest moments.

Researchers are exploring MXenes, 2D materials that could transform air into ammonia for cleaner fertilizers and fuels. Their atomic structures can be tuned to optimize performance, making them promising alternatives to expensive catalysts.

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By rethinking gravity and cosmic timelines, it could rewrite our understanding of space and time itself.

A team of astrophysicists has unveiled how colossal stars thousands of times more massive than the Sun shaped the earliest star clusters and galaxies. These short-lived giants not only forged the strange chemical fingerprints found in ancient globular clusters but may also have been the seeds of the universe’s first black holes.

Evidence now suggests the universe’s expansion has started to slow, not speed up. The findings imply dark energy is weakening, marking a possible revolution in cosmology.

Astronomers have discovered that aging stars may be devouring their closest giant planets as they swell into red giants. Using NASA’s TESS telescope to study nearly half a million stars, scientists found far fewer close-orbiting planets around older, expanded stars—clear evidence that many have already been destroyed.
