Tabby's star may be orbited by a planetary-mass companion
By analyzing data from NASA's Transiting Exoplanet Survey Satellite (TESS) and conducting new radial velocity measurements, U.K. and French astronomers have found evidence that the mysterious Tabby's star may be orbited by an object about nine times more massive than Jupiter.
Neuroscientists reveal limits of human compassion for global crises
New research from the University of Sussex has revealed the biological limits to human compassion and empathy. The study found a stark contrast between how the brain processes information about risk to human lives and information about financial risk and could help explain why
New Ribo-Tweezer tool can pluck individual protein pieces out of a working ribosome
Every human cell has millions of ribosomes that make proteins. For decades, biologists thought of ribosomes as tiny, uniform machines. But now a Stanford Medicine team is showing that ribosomes are much more interesting and complicated than previously thought.
Martian space suits will need to be 40% lighter
Long before a human ever sets foot on the Red Planet, we already know how harsh the environment is. Once a human finally does, the only things protecting them from that environment will be the infrastructure we've built there and the spacesuit that keeps them in a protective
Review explains links between plasmids, horizontal gene transfer and antimicrobial resistance
The arms race between bacteria and antibiotics is nothing new—antimicrobial resistance has been an emerging issue in human and animal health for a long time. But in a new review published in JAC-Antimicrobial Resistance, NC State researchers used a One Health approach to study
Helical nanoparticles trigger cancer alarms and deliver gene therapy
Cancer cells survive by hiding from the immune system's surveillance. A KAIST research team has developed a new anticancer platform that makes cancer cells send out their own danger signals—prompting immune cells to attack—while simultaneously delivering gene therapy. The
Chicxulub's lingering dust may have turned falling debris into a global firestorm
Sixty-six million years ago, the six-mile-wide (10-kilometer-wide) Chicxulub asteroid crash-landed in Mexico's Yucatán Peninsula and changed life on Earth forever. The reign of the dinosaurs ended, and only creatures that could shelter in burrows or shallow waters survived into
Climate change and social concerns could drive more radical protests
Around the world, hundreds of thousands of people engage in conventional protests—and sometimes more radical forms of action—in the face of environmental change, harms to animals and nature, and climate inaction.
‘Forever chemicals’ could be aging dolphins beyond their years
Common dolphins in New Zealand are biologically older than their calendar ages. Trace metals and “forever chemicals” may be to blame.
More evidence Mars once had water emerges from old Spirit rover data
More than 20 years after NASA's Spirit rover landed on Mars, a researcher from Edith Cowan University (ECU) has uncovered new evidence that suggests water may once have covered large parts of the red planet.
More green space alone won't beat urban heat
New research from Victoria University (VU) reveals that reducing the impact of extreme heat in urban areas requires more than simply adding green spaces—it requires a different approach to urban planning.
A slowing Atlantic current could unleash stronger California storms
A weakening Atlantic current could supercharge California’s atmospheric rivers while leaving Greenland with fewer snow-producing storms. The changes could raise flood risks, strain infrastructure, and reshape water supplies far beyond the Atlantic.
JWST could spot volcanic 'exo-Ios' around super-Jupiters
Jupiter's moon Io is the most volcanically active planetary body in the solar system, boasting hundreds of active volcanoes that spew molten lava into space. This activity results from a process called tidal heating, in which Jupiter's massive gravity constantly stretches and
Cracking the axolotl code: How to regrow limbs and stay young
Minor cuts and scrapes usually heal in time, but losing a finger or a whole limb? For most vertebrates, that's a done deal. Unless, of course, you've got the self-healing machinery of an axolotl.
Astronomers find strongest evidence yet that Betelgeuse has a companion
At long last, astronomers have firm evidence that Betelgeuse, one of the most famous stars in the night sky, is not alone. Using the European Southern Observatory's Very Large Telescope (ESO's VLT), a team led by French researcher Miguel Montargès obtained the clearest image

Misfolded insulin may be quietly driving diabetes
Researchers found that insulin-producing cells depend on a team of helper proteins to keep insulin production on track. When one key partner was missing, damaged proteins built up and the cells made less insulin. Strengthening this system could offer a new way to protect the

Hidden charcoal reveals the true age of ancient cave paintings
A new analysis has precisely dated paintings in France’s Font-de-Gaume cave for the first time. Scientists discovered charcoal inside black pigments once thought to contain only minerals, allowing them to use radiocarbon dating. The results show that a bison was painted about
Benefits of middle school program trickle down to next generation
A substance-use prevention program delivered to students and their families in the sixth and seventh grades led to wide-ranging benefits well into adulthood and—for those who became parents—even positively affected their children, according to a new study by researchers in the
Moon's thick crust could amplify elusive gravitational-wave signals
Gravitational waves are tiny ripples in the fabric of spacetime that are produced when massive objects in the cosmos accelerate or collide. By detecting these waves, astrophysicists can study various cosmic events, including black hole mergers, neutron star collisions and the
Record snow drought drives water-hauling crisis for Rocky Mountain ranchers
As water shot into an open stock tank atop a high-country mesa, a trickle soaked the dusty earth below. Scott Snyder rose from the shade to fasten a hose and stop the spillage.
Why losing weight may not be enough to prevent type 2 diabetes
A healthy lifestyle can prevent type 2 diabetes for many people, but new research suggests that weight loss alone may not be enough for one particularly vulnerable group. Even after losing about 8% of their body weight and keeping it off for years, people in a high-risk
AI-powered camera system offers low-cost way to monitor bumblebees, potentially other insects
Researchers have developed a low-cost, semi-automated, AI-driven method that uses remote cameras to survey bumblebees and potentially other insects. The new tool could have important implications for efforts to conserve declining insect populations. Several bumblebee species
