Mars fungi could make red planet regolith fertile for crops
You're on the fourth human mission to Mars, and you've been tasked with establishing the first self-sustaining food crop on a Martian settlement. You're nervous because you're using a new type of fungi called beneficial fungi, which you're told will help enhance the Martian
Analysis reveals overseas environmental toll of UK consumption
British demand for everyday global commodities can be linked to more than 29,000 hectares of deforestation worldwide in a single year, with tens of thousands of hectares stripped directly from overseas ecosystems. The stark figure forms the centerpiece of an environmental
Rodent eradication sparks insect boom on Lord Howe Island
The removal of invasive rodents from Lord Howe Island has triggered a rebound of invertebrate life, with researchers from the University of Sydney and collaborators documenting sharp increases in the abundance of insects and other small animals that underpin the island's

A battle between “slimes” and “zoglins” could be the best way to calculate pi—at least for fans of this megahit game
Experts explain how sunscreen really works—and why better ones may be coming soon
Thick and creamy, gloopy or spray-on, sunscreen can be confounding. This science-backed guide can help you get ready for summer
Mars astronauts may do laundry by blasting clothes with a plasma beam
There is currently no good way for astronauts in space to do laundry, but researchers may have finally come up with one: a bright purple jet of microbe-killing plasma
Why your brain needs plenty of “Aha!” moments
In the age of AI, instant answers to our questions are readily available. But columnist Helen Thomson finds that continuing to encourage those delicious flashes of insight that come from your own thoughts may be beneficial both for your everyday life and your long-term brain
Tropical cyclones now release ocean carbon, but warming could flip role by 2035
The ocean is an important carbon sink that absorbs 20–30% of the total anthropogenic CO2 emissions in the industrial era (1.0–3.0 Pg annually, 1 Pg = 1015 g). Tropical cyclones are among the most devastating weather systems that profoundly disturb the upper ocean. However,
The Southwest's drought is shrinking wildlife's suitable habitat, with predators hit hardest
As people in the United States are coping with historic drought conditions, the country's wildlife is also facing problems because of the extreme aridity. Herbivores, omnivores, and carnivores in the southwestern U.S. have all seen the extent of their suitable habitat shrink
China launches crewed space flight as part of moon ambitions
China launched its crewed Shenzhou-23 spacecraft and eased it into a successful docking with a space station early Monday as part of Beijing's ambitions to send humans to the moon by 2030, state media said.
With ice cream and giant fans, hajj pilgrims battle searing heat
To avoid the punishing sun, Inas Gamal abandoned her ambitious plan of spending the days ahead of the hajj praying in Mecca's Grand Mosque and retreated to the comfort of an air-conditioned hotel room to perform her daytime prayers.
Adorable tiny blue octopus found nearly 6,000 feet beneath the Galápagos
A mysterious little blue octopus discovered nearly 6,000 feet beneath the waters of the Galápagos Islands has officially been identified as a brand-new species. About the size of a golf ball, the tiny creature stunned researchers during a deep-sea expedition when it suddenly
Beet juice lowers blood pressure in older adults in just 2 weeks
Drinking nitrate-rich beetroot juice may do more than support heart health — it could actually reshape the bacteria living in the mouth in ways that help lower blood pressure in older adults. In the largest study of its kind, researchers found that older people who drank
Scientists supercharge natural killer cells to fight aggressive cancers
Scientists at McGill University have found a way to supercharge the immune system’s natural killer (NK) cells, helping them break through the defenses tumors use to stay alive. By temporarily blocking two proteins, researchers turned these cells into far more effective cancer
Scientists discover hidden liver switch that cuts harmful cholesterol
Scientists at UT Southwestern have uncovered a surprising new “master switch” that helps control how much cholesterol the liver sends into the bloodstream. The newly identified protein, HELZ2, works by shutting down the genetic instructions needed to produce apoB — a key
Expedition to Hess Rise in the Northwest Pacific begins
Located in the middle of the North Pacific, between Japan and Canada, lies one of the world's largest oceanic plateaus, the so-called Hess Rise. The plateau is roughly T-shaped and extends over a length of about 1,000 kilometers. Due to its distance from the nearest mainland,
This tiny blue octopus from the Galápagos could curl up in your hand and shows how much deep ocean remains unexplored
The Galápagos Islands off the coast of Ecuador are home to more than a thousand plant and animal species found nowhere else on Earth—things like marine iguanas and giant tortoises. In a new paper in the journal Zootaxa, scientists have announced the discovery of the newest
The Pennine hills are full of holes—here's how they're helping fight climate change
Thousands of holes are appearing in the Pennine hills, as part of efforts to improve carbon storage by restoring damaged peatland.
Cooling poverty is making extreme heat more dangerous for millions
Imagine walking along Ipanema beach on a summer afternoon. The sand is golden, there's a cooling sea breeze, the shade of a parasol and a cold drink in hand. Now look up.
Graphene quantum dots show promise in targeting Parkinson's-related protein clumping
The buildup of a protein called 𝛂-synuclein (ASN) into toxic clumps is a hallmark of synucleinopathies, a group of neurodegenerative diseases that includes Parkinson's and multiple system atrophy (MSA). These aggregates are associated with cellular dysfunction and lead to
Fear silences women politicians in public debate, surveys suggest
Women politicians are significantly more likely than their male colleagues to refrain from speaking out in public for fear of threats or harassment—particularly on issues relating to migration and gender equality. Politicians with an immigrant background are also more likely to
When order gives way to chaos—the turbulent birth of magnetic nanovortices
Magnetic switching processes are considered a prime example of controllable physics at the nanometer scale: in certain thin-film systems, a short electrical current pulse is sufficient to reverse the magnetization in a targeted way. The underlying effect is the so-called
Companies struggle to realize circular ambitions, says researcher
The research, conducted by Wierikx at the Department of Industrial Engineering & Innovation Sciences, is based on more than 3,000 organizational assessments. The results reveal a consistent pattern: companies are relatively strong in setting circular ambitions, but face major
New 'AI scientists' are improving—but reveal their fundamental limits
Many of the most exciting discoveries in science involve highly specialized knowledge and making connections between far-flung facts. Scientists must combine deep analysis with broad reasoning strategies.
Not just a fun hobby: Board games can help build connections and reduce stress
Researchers at the University of Plymouth recently confirmed what board game fans and role-playing game (RPG) enthusiasts have known for decades: that tabletop games "enhance well-being, foster inclusion, and support learning, with strong evidence that games improve engagement."
