AI can now control fusion plasma faster than humans can react

Princeton researchers have tested an AI system that can monitor and control fusion plasma in milliseconds, reacting far faster than a human operator. In one experiment, it predicted a damaging instability about 200 milliseconds before it appeared and adjusted the plasma to stop it from forming.

This “new” frog was hiding in plain sight for 100 years

A common frog found across Ecuador and Colombia has finally been recognized as its own species after more than a century of mistaken identity. Museum specimens from the 1800s helped scientists reveal that Pristimantis milpe had been hiding in plain sight all along.

Quantum oscillations defy expectations in this exotic material

Scientists have uncovered an unusual form of electron behavior in zirconium pentatelluride, a quantum material that can act as both an insulator and a conductor. Under temperatures near absolute zero and magnetic fields reaching 60 tesla, electrons produced quantum oscillations that continued even after conventional physics predicted they should disappear.

Scientists overturn a theory about this shark’s strange head

Scientists have overturned a leading explanation for why male and female bonnethead sharks have differently shaped heads. Instead of males developing a pointed snout at maturity, both sexes actually begin with more pointed heads that become rounder with age, particularly in females.

MIT turns bacteria into living transistors

MIT researchers have created bacterial “transistors” that can be wired together into living circuits capable of performing calculations and directing chemical signals. One day, these biological computers could coat plant roots or leaves, detecting environmental threats and automatically triggering defenses.

Dying radio galaxies fade faster than scientists expected

Astronomers have identified a surprisingly young population of fading radio galaxies whose supermassive black holes have already switched off their powerful jets. The confirmed remnants range from about 8 to 42 million years old, suggesting many may disappear from view much faster than previously recognized. More distant remnants also seem to fade especially quickly, helping explain why they have been so difficult to detect.

Scientists just overturned a century-old physics assumption

Scientists at Carnegie Mellon University have discovered an unexpected form of the Hall effect, overturning the long-held assumption that this electrical response only appears when a magnetic field points perpendicular to a material. Beyond expanding a century-old principle of physics, the finding could eventually lead to simpler magnetic sensors for electronics, transportation, and medical technologies.

ADHD may have a surprising creative advantage

Some of the attention patterns that make ADHD challenging may also help spark creativity by allowing the brain to explore more ideas and unexpected connections. Researchers think creative activities could potentially channel this “defocused attention” while helping strengthen the brain systems involved in focus and self-control.

Alzheimer’s may leave a mark on the brain long before plaques appear

Brain changes associated with Alzheimer’s may begin at least seven years before amyloid plaques become detectable with current PET scans. Researchers uncovered the signal by tracking healthy older adults with repeated brain imaging over nearly 20 years. The discovery could help scientists identify Alzheimer’s earlier and suggests that important disease processes may start before visible plaque buildup.

A search for one exotic particle uncovered two strange new structures

A search for one mysterious particle unexpectedly revealed evidence for two different structures that may belong to the bizarre family of exotic subatomic particles known as XYZ states. The findings could help physicists uncover new ways that quarks and gluons combine to create matter.

Reaching 90 without dementia doesn’t mean you’re in the clear

A study of people over 90 found that dementia risk remains strongly shaped by sex, race and genetics, with women and black participants facing notably higher risks. Intriguingly, some people stayed cognitively healthy despite carrying major risk factors, potentially offering clues to how the brain can resist dementia deep into old age.

Scientists discover two superconducting states hiding as one

Scientists have uncovered hidden complexity inside two ultrathin superconductors that seemed much simpler than they really are. Niobium diselenide and tantalum disulfide appeared to have a single superconducting state, but highly sensitive measurements revealed that each actually contains two strongly interacting states working so closely together that they masquerade as one.

Rocky planets may have formed just 100 million years after the Big Bang

Rocky planets may have been able to start forming just 100 million years after the Big Bang, thanks to enormous early supernovae that scattered planet-building elements across space. Simulations found enough solid material and water around a young star to suggest that Earth-like worlds could have appeared far earlier than previously believed.
