The Science      Newswise — Tokamaks are donut-shaped fusion devices that use magnetic fields to confine plasma. They are a leading design for fusion power plants in the future. However,…

Rachel Feltman: For Scientific American’s Science Quickly, I’m Rachel Feltman. Today we’re taking a break from science fact to talk about some recent science fiction. My guest is journalist, editor…

NASA’s OSIRIS-REx mission encountered an unexpected mystery when it arrived at asteroid Bennu in 2018. Instead of the relatively smooth terrain that earlier observations had suggested, the spacecraft found a…

Your dreams may not foretell the future, but the way that your heart falls asleep just might. Researchers have now shown that in the early stages of sleep, as the…

Protecting brain cells from destruction remains one of the biggest challenges in treating Alzheimer’s disease and related neurodegenerative conditions. These disorders, known as tauopathies, involve the buildup of abnormal tangles…

To us mortals, the flow of time goes one way. Yesterday is gone, tomorrow is yet to come, and no matter how precisely and faithfully a clock marks the passing…

One of science’s greatest strengths is its capacity to learn from mistakes. Confronted with an error, a good scientist will admit to being wrong and use the new information to…

US researchers have built a brain-like computer chip that can analyze fusion plasma at one million samples per second. Fusion reactors heat plasma to temperatures roughly 10 times hotter than…

Some galaxies glow with sweeping spiral arms, while others are shaped by violent collisions, powerful black holes, and explosive bursts of star formation. A newly released collection of 16 images…

Who created AI in the Marvel Cinematic Universe? When it comes to J.A.R.V.I.S., Vision, and Ultron, the short answer is Tony Stark, with a little help from Bruce Banner. But…

Growing older is often associated with memory loss and declining mental abilities. However, scientists are questioning whether these changes tell the whole story. Rather than simply becoming less capable, the…

Our ever-shrinking group of media conglomerates is concerning for many reasons, but at least it makes for some bizarrely fascinating moments of brand synergy. It’s interesting, to say the least,…

A major federal grant program that helps researchers purchase scientific equipment has seemingly gone dark, leaving scientists unsure of whether they will be able to apply for funding. The National…

Scientists have measured the amount of helium produced during the Universe’s first five minutes with unprecedented precision, offering a clearer picture of the conditions that existed shortly after the Big…

In the brains of people with Alzheimer’s and certain other types of dementia, two proteins called amyloid-beta and tau start misbehaving in different ways – though it’s not clear if…

A new Albuquerque mixed-use neighborhood called Mesa del Sol, near the airport, is still under construction. But it’s coming together: earth-toned homes have popped up; rock-based snake sculptures line the…

This problem is the result of many hours of cleaning baby bottles for two daughters. Suppose your baby uses a certain type of bottle that is composed of three pieces…

Scientists who worked out how to control brain cells with light have won this year’s Nobel prize in physiology or medicine. Karl Deisseroth, Peter Hegemann and Georg Nagel were honored…

Chemists are closing in on alternative compounds to protect tyres against ozone damage while causing less harm in the environment. The search has been on since 2020, when rubber additive…

A tiny amount of metal could be standing between us and practical nuclear fusion. And ironically, it’s the very metal engineers use to protect fusion reactors from extreme heat. That…

Actress Christina Applegate’s announcement on Tuesday that she was misdiagnosed with multiple sclerosis (MS) in 2021 immediately made headlines. Her experience, while not the norm, is far from unusual, experts…

Google’s AI explored magnetic field equations relevant to experimental fusion reactors AI agents found new magnetic configurations within hours of starting their investigation Gemini helped extend mathematical solutions linked to…

A population of once-rare hybrid crabs has surged to record numbers, following a marine heatwave that hit the Bering Sea in 2018. This dramatic increase in hybrid crabs is not…

Japan’s mission to collect samples from a Martian moon is off to a good start. Launched atop an H3 rocket from Tanegashima Space Center just after 3:40 P.M. EDT on…

Astronomers have long depicted distant exoplanets with smooth, circular outlines. But new observations reveal that the atmospheres surrounding some of these scorching alien worlds can have surprisingly uneven shapes. Using…

Aging is the price paid for the ability of experiencing existence, one might philosophize. Natural cellular aging begins with differentiation. Once a stem cell becomes a specific cell type, it’s…

A new study suggests that even low levels of physical activity could protect the brain from Alzheimer’s disease – but not in the way scientists expected. The researchers tracked almost…
