AI uncovers how a severed bond between two gut proteins sparks Crohn’s disease, and how restoring it could heal inflammation. UC San Diego researchers combined artificial intelligence with molecular biology to unravel how immune cells in the gut decide between inflammation and healing, a process gone awry in Crohn’s disease...

In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions.

“The real challenge, the thing that stops us from having useful quantum computers today, is that you build a qubit and the information just doesn’t last very long,” said Andrew Houck, Princeton’s dean of engineering and co-principal investigator. “This is the next big jump forward.”

In an article in the journal Nature,...

The universe’s expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously thought, a new study suggests.

“Remarkable” findings published today in Monthly Notices of the Royal Astronomical Society cast doubt on the long-standing theory that a mysterious force known as ‘dark energy’ is driving distant galaxies away increasingly faster.

Instead, they show no evidence of an accelerating universe.

If the results are confirmed, it could open an entirely new chapter in scientists’ quest to uncover the true nature of dark energy, resolve the ‘Hubble tension,’ and understand the past and future of the universe.

Long-term melatonin use may secretly strain the heart—raising the risk of failure, hospitalization, and death. Long-term melatonin use for sleep problems may come with unexpected heart dangers. Researchers found that chronic users were almost twice as likely to die and 3.5 times more likely to be hospitalized for heart failure. Though melatonin is widely regarded as harmless, experts now urge caution with extended use.

Key Research Findings

A large review of health data from more than 130,000 adults with insomnia found that people who took melatonin for a year or longer were more likely to develop heart failure, be hospitalized for the condition, or die from any cause compared to those who didn’t take the supplement.
While the study cannot prove that melatonin directly causes t...
