Popular sweetener byproduct damages DNA in human cells

Sucralose, the artificial sweetener used in Splenda, came under scrutiny after a study found that a related chemical damaged DNA and weakened the gut barrier in laboratory experiments. But later findings have complicated that alarming picture.

Consumers demand transparency, but is it rewarded?

Transparent supply chains boost consumer trust—if the results are positive. But what if they aren't? A new paper by Kühne Logistics University (KLU), in collaboration with the University of Tennessee and Tilburg University, published in the Journal of Business Logistics, reaches a surprising conclusion. The researchers advise companies: It's better to publish mixed results than none at all.

JWST ruled out finding tiny moons around an exoplanet—that's great news

The James Webb Space Telescope (JWST) has opened many wonders of the cosmos to scientists since it began science operations a few years ago. But one thing it hasn't done is find an "exomoon." These still-theoretical moons orbit exoplanets in other star systems, and JWST was supposed to find a plethora of them.

Astronomers unmask a supernova impostor

A distant star has captured astronomers' attention over the past decade, teasing them with indications that it will soon explode as a supernova. But new research shows that something else entirely is behind the star's outbursts. Rather than an impending catastrophic explosion, a previously unseen companion may be responsible for the star's behavior.

AI helps microscopes find the most informative nanoscale features in a sample

Researchers at the Department of Energy's Oak Ridge National Laboratory (ORNL) have developed an artificial intelligence framework that helps researchers use atomic force microscopes to identify important nanoscale features while autonomously targeting the most informative areas of a sample for closer study.

Masked tectonic structures suggest Mercury contracted 40% more than its visible scars alone indicate

The surface of Mercury is filled with craters, ridges and steep cliffs. Over billions of years, as the planet's interior cooled, the planet also shrank. Just as the skin of a drying fruit wrinkles when what is inside it shrinks, Mercury's rocky surface crumpled into ridges and cliffs as its interior cooled and the planet contracted. Mercury has quite literally grown smaller with age.

Fall stargazing 2026: The best skywatching sights in autumn (and how to see them)

With fall now upon us, many of us will be dusting off our binoculars and telescopes ready for the longer nights this season brings. Earlier sunsets mean more stargazing hours, and we'll start to see the return of some favorite celestial sights and deep-sky objects that we haven’t seen since before spring. Fall is also an excellent time for casual stargazers, with the earlier evenings and cooler temperatures offering a comfortable compromise before we head into those freezing winter nights when we can't feel our toes. Don't worry if you're just starting out and don't have any gear yet, as many of this season's celestial objects are visible with the naked eye — and some are actually best viewe...

AI automates 3D membrane mapping, matching manual results in a fraction of time

Cell membranes and the proteins within them control many vital processes and play a key role in health and disease. But studying them in 3D images of cells has so far meant slow, manual work. A team from Helmholtz Munich, the Technical University of Munich (TUM) and the Biozentrum of the University of Basel has developed MemBrain v2, an AI tool that automates this task—cutting work that once took weeks down to a few hours. The study is published in Nature Methods.

Luminescence dating pushes age of South Dakota's Mammoth Site back by more than 100,000 years

Deep within an ancient sinkhole lie the remains of dozens of mammoths, prehistoric wanderers who waded into the warm springs to their deaths. These deaths had long been accepted as having occurred roughly 26,000 years ago, but new dates published in the journal Quaternary Research suggest these ice-age giants were more than 160,000 years old.

The tourism industry is slowly waking up to solo travelers' needs

Solo travel is surging—and an industry still largely built for two is taking note. Google reported in April 2026 that online searches involving "solo travel" hit an all-time high this year, with queries for "women solo travel" reaching a 15-year peak. Hilton's 2026 trends report found that 26% of travelers planned to take a trip alone this year and that nearly half said they planned to add solo days to the front or back of a family trip.

Gravitational-wave analysis narrows the search for black hole impostors

Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape. When two black holes orbit each other and merge, they produce gravitational waves (i.e., ripples in spacetime) that can resemble those emitted by mergers involving other exotic compact objects.

Scientists find a new layer of Alzheimer’s hidden in the genome

Scientists found that the 3D organization of DNA is disrupted in several types of brain cells affected by Alzheimer’s disease, altering how important genes are switched on and off. The discovery reveals a previously underexplored layer of the disease that could open new paths for understanding and eventually treating Alzheimer’s.

Physicists can’t agree on how the Universe works

A massive worldwide survey of physicists has revealed surprisingly little agreement about some of the universe’s biggest mysteries. No majority backed the standard cosmological model, a leading explanation for dark matter, or any single theory of quantum gravity. One area of stronger agreement stood out: 68% said the Big Bang does not necessarily represent the beginning of time. Researchers say the divisions show just how alive and unsettled the frontiers of physics remain.

NASA's next great observatory could spot oceans on distant worlds

We've found more than 5,500 exoplanets so far. Dozens of them are in the habitable zones of their parent stars, where, at least in theory, they could host an ocean. But we've never definitively found a liquid ocean on another planet.

Most men don’t know dairy is linked to prostate cancer risk

Most men may be missing an important dietary clue about prostate cancer. A new survey found that only 20% knew research has linked dairy consumption with increased prostate cancer risk, while 66% said they would consider avoiding dairy after learning about the connection. Studies have also associated plant-based diets with substantially lower risks of prostate cancer, progression, and recurrence.

Global warming is breaking a 400-year climate link between two oceans

The Indian and Pacific oceans have been climatically linked for centuries, but scientists say that connection is now breaking down in an exceptional way. Ancient climate records suggest volcanoes disrupted the relationship in the past, while today human-caused warming appears to be driving a much more unusual shift.
