The new superconducting magnets will produce fields about 40% stronger, allowing particle beams to be squeezed more tightly before they collide. That should create far more collisions for the ATLAS and CMS experiments to analyze, giving physicists a much larger window into the fundamental workings of the universe.

Another is frequently covered in tiny parasites, and researchers say many more undiscovered sea spiders may still be hiding in the region.

Its magnetic field may be partly responsible, but astronomers say an unexplained “mystery engine” may also be at work.

In a 30-patient trial, the edited cells successfully took hold and appeared to shield blood cells from a CD33-targeted cancer treatment.

Researchers warn that thousands of cases may remain hidden because genetic testing is often not performed, even as targeted treatments move into clinical trials.

The discovery suggests magnetism worked alongside gravity to help transform a vast cloud of gas and dust into the sun and planetary disk.

The shift suggests that rising diagnosis rates may partly reflect broader identification and changing diagnostic patterns, rather than only an increase in the underlying conditions.

The finding, combined with similar evidence from Miranda, suggests the distant Uranian system could harbor multiple hidden ocean worlds.

The coupling is carried by spin-polarized electrons, allowing time crystals separated by up to 40 micrometers to lock to a common frequency. The discovery reveals surprisingly long-range connections between these exotic spin systems and could help researchers develop future spin-based devices.

Researchers found that removing a protein called NUDT5 protected cells from the drug, even though simply blocking the protein had little effect. The unexpected result points to a hidden cellular role that could help explain why people respond differently to certain leukemia treatments.

People who spent more time in REM sleep had lower risks of 83 conditions, including dementia, heart failure, and Parkinson’s disease, while more deep sleep was associated with lower risks of conditions such as type 2 diabetes and major depression.

Researchers found that matching signals between two visual areas lasted longer, while conflicting signals rapidly faded away. This “consensus building” mechanism could help explain how the brain turns many specialized inputs into one unified view of the world.

Researchers found that stellar winds weaken sharply at extremely low metallicities, potentially allowing massive stars to retain more material and evolve in unexpected ways. The team also found large differences in iron abundance, a key ingredient in stellar winds and supernovae.

Researchers identified unusual sediment layers suggesting that earthquakes on the two systems have occurred just minutes to hours apart, including around the massive Cascadia earthquake of 1700. If such synchronization happened again, several major West Coast cities could face emergencies at nearly the same time.

By blocking tiny blood vessels associated with inflammation, GAE can significantly reduce pain, with some patients reporting little or no pain afterward. Studies suggest the benefits may last two to four years in people who respond well.

But the enduring popularity of the Viking myth means exhibitions often balance historical accuracy with stories that reflect modern ideas about national identity and culture.

Individual sensitivity varies dramatically, meaning even caffeine consumed earlier in the day could affect nighttime recovery for some people.

The possible multistage journey suggests remarkable organization and raises the possibility that the stone was valued long before it became part of Stonehenge.

By comparing three Clusia species, researchers discovered that this water-saving form of photosynthesis, known as CAM, did not arise through a single evolutionary change. Instead, ancient genome duplications followed by millions of years of genetic reshuffling produced strikingly different strategies, from strong CAM to stress-triggered and hybrid forms.

Lake Mead also reached record lows, raising concerns for a river system that supplies water and power to more than 40 million people. Federal officials have taken emergency steps to stabilize Lake Powell, including sending in water from another reservoir and reducing releases downstream.

Scientists say changing clouds and increasingly thin ice may explain the pause, but continued Arctic warming could eventually trigger another period of rapid change.

In a worst-case scenario, those signals could culminate in a VEI 8 eruption that blasts ash tens of kilometers into the atmosphere, unleashes deadly pyroclastic flows, buries parts of the western United States in ash, and cripples transportation, electricity, water systems, agriculture, and communications across much of North America.

Children with a congenital TORCH infection were about three times more likely to be diagnosed with autism, more than seven times more likely to have an intellectual disability, and up to 30 times more likely to have severe to profound intellectual disability.

Preventing damage from wildfires and logging delivered the greatest biodiversity benefits and nearly matched deforestation prevention for protecting carbon. Restoration remains important, particularly where forests have already been heavily cleared, but it was more expensive and less effective on its own.

People with the highest inflammation levels faced a 43% greater risk of heart attack and stroke, raising hopes that earlier testing and anti-inflammatory treatments could help prevent serious heart disease.

The discovery also allowed researchers to grow human hindbrain neurons in the lab, opening new possibilities for studying ALS, spinal muscular atrophy, and other brainstem diseases.

Deep beneath Italy’s Gran Sasso mountain, researchers searched for an extremely faint radiation signal predicted by a theory suggesting that tiny fluctuations in spacetime, caused by gravity, gradually destroy quantum superpositions. After 62 days of measurements with a highly shielded germanium detector, they found no such signal.

The discrepancy is tiny, but for one of nature’s most fundamental constants, it is large enough to keep scientists wondering whether hidden experimental errors or something more surprising is involved.

Researchers identified eight widely used preservatives associated with hypertension, although the observational study cannot prove they were directly responsible.

Researchers say the findings challenge routine supplementation for prevention and point instead toward strategies such as balance and resistance exercise.

Experts warn that preparing only for familiar pathogens could leave the world vulnerable when rare but deadly viruses suddenly reemerge.

Japan’s upcoming MMX sample return mission could provide the measurements and physical evidence needed to solve the mystery.

The findings could give forecasters an earlier warning that a seemingly disorganized storm is becoming primed to strengthen.
