Bacteria use sugar-fueled currents and molecular gearboxes to move without flagella
New studies from Arizona State University reveal surprising ways bacteria can move without their flagella—the slender, whip-like propellers that usually drive them forward.
How countries can be held responsible for staying within new legal climate target of 1.5°C
Global emissions need to peak this year to stay within 1.5°C of global temperature rise since pre-industrial levels. This means that starting now, countries need to emit less greenhouse gases. Emissions also need to be cut in half by 2030 to prevent the worst effects of climate
The 'anti-weather' of Venus
Conditions on Venus's surface have largely remained a mystery for decades. Carl Sagan famously pointed out that people were quick to jump to conclusions, such as that there are dinosaurs living there, from scant little evidence collected from the planet. But just because we
Rainfall's origin reveals a hidden driver behind drought risks for farmers
A new University of California San Diego study uncovers a hidden driver of global crop vulnerability: the origin of rainfall itself.
Empowering street vendors in Indonesia through a sustainability-integrated financial literacy program
Earlier this year our Grantham Scholar, Eva Andriani, traveled to Indonesia to conduct some participatory research with a community of street vendors. We spoke to Eva to find out about her experience and the impact of her research.
Geopolitics, backsliding and progress: Here's what to expect at this year's COP30 global climate talks
Along with delegates from all over the world, I'll be heading to the United Nations COP30 climate summit in the Brazilian Amazon city of Belém. Like many others, I'm unsure what to expect.
A 500-million-year-old brain "radar" still shapes how you see
New research shows that the superior colliculus, a primitive brain region, can independently interpret visual information. This challenges long-held beliefs that only the cortex handles such complex computations. The discovery highlights how ancient neural circuits guide
Scientists find brain cells that could stop Alzheimer’s
Researchers have identified special immune cells in the brain that help slow Alzheimer’s. These microglia work to reduce inflammation and block the spread of harmful proteins. They appear to protect memory and brain health, offering a promising new direction for therapy.
We studied 217 tropical cyclones globally to see how people died. Our findings might surprise you
Tropical cyclones—also known as hurricanes, typhoons or storms, depending on their location and intensity—are among the world's most destructive and costly climate disasters.
New laser treatment could stop blindness before it starts
Aalto University scientists have created a laser-based treatment that uses gentle heat to stop the progression of dry macular degeneration. The approach stimulates the eye’s natural cleanup and repair systems to protect against blindness.
Common pesticides may cause testicular damage and lower sperm counts
A decade-long review by George Mason University researchers reveals growing evidence that neonicotinoid insecticides—the world’s most widely used class of pesticides—may harm male reproductive health. The findings, based on 21 animal studies, show consistent links between
Climate intervention may lower protein content in major global food crops
A new study in Environmental Research Letters reports that cooling the planet by injecting sulfur dioxide into the stratosphere, a proposed climate intervention technique, could reduce the nutritional value of the world's crops.
Saturday Citations: Black hole flare unprecedented; the strength of memories; bugs on the menu
This week, researchers reported finding a spider megacity in a sulfur cave on the Albania-Greece border, and experts say that you, personally, have to go live there. Economists are growing nervous about the collapse of the trillion-dollar AI bubble. And a new study links
Water temperatures in Amazonian lakes rise to unprecedented levels, killing wildlife
During a severe drought and heat wave in 2023, Amazonian lakes reached their highest recorded temperatures. Water temperatures in some areas climbed to an astonishing 41 degrees Celsius (105.8 degrees Fahrenheit) and resulted in the deaths of thousands of aquatic animals,
Rubin Observatory Discovers Surprise ‘Tail’ on Iconic Galaxy
The first image from the Vera C. Rubin telescope reveals a previously unnoticed feature of the galaxy M61 that may explain its mysterious properties
Spins influence solid oxygen's crystal structure under extreme magnetic fields, study finds
Placing materials under extremely strong magnetic fields can give rise to unusual and fascinating physical phenomena or behavior. Specifically, studies show that under magnetic fields above 100 tesla (T), spins (i.e., intrinsic magnetic orientations of electrons) and atoms
'Almost every day': Japan battles spike in bear attacks
The sense of fear is palpable in parts of northern Japan, where some locals have fastened bells to their bags hoping the noise will keep bears away, while signs warn people to be on guard.
Rare footage shows sucker fish as they whale-surf in the ocean's wildest joyride
There are easier ways to cross an ocean, but few are as slick or stylish as the remora's whale-surfing joyride.
James Watson, co-discoverer of the double-helix shape of DNA, has died at age 97
James D. Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died. He was 97.
COVID vaccine linked to fewer infections and allergies in kids with eczema
New research suggests the COVID-19 vaccine could help children with eczema stay healthier overall. Vaccinated kids had lower rates of infections and allergies, including asthma and rhinitis, compared with unvaccinated peers. Experts believe the vaccine may help prevent allergic
MIT quantum breakthrough edges toward room-temp superconductors
MIT scientists uncovered direct evidence of unconventional superconductivity in magic-angle graphene by observing a distinctive V-shaped energy gap. The discovery hints that electron pairing in this material may arise from strong electronic interactions instead of lattice
Einstein might have been wrong about black holes
Researchers are using black hole shadows to challenge Einstein’s theory of relativity. With new simulations and future ultra-sharp telescope images, they may uncover signs that his famous equations don’t tell the whole story.
Deep-sea mining starves life in the ocean’s twilight zone
Scientists have discovered that deep-sea mining plumes can strip vital nutrition from the ocean’s twilight zone, replacing natural food with nutrient-poor sediment. The resulting “junk food” effect could starve life across entire marine ecosystems.
Laser satellites expose a secret Antarctic carbon burst
A new study shows that the Southern Ocean releases far more carbon dioxide in winter than once thought. By combining laser satellite data with AI analysis, scientists managed to “see” through the polar darkness for the first time. The results reveal a 40% undercount in winter
Nanoparticles that enhance mRNA delivery could reduce vaccine dosage and costs
A new delivery particle developed at MIT could make mRNA vaccines more effective and potentially lower the cost per vaccine dose.
A hidden cellular cleanup trick could reverse aging
Researchers found that the body’s natural recycling system, the lysosome, plays a vital role in removing the protein that drives premature aging. When this system breaks down, aging speeds up. By reactivating it, scientists were able to help cells recover their youthful
Turning undersea cables into a global monitoring system for seismic and environmental hazards
EU researchers are exploring how undersea communication cables can double-up as environmental and seismic sensors—a potential game-changer for early warning systems.
Stanford makes stem cell transplants safer without chemo
A Stanford-led team has replaced toxic pre-transplant chemotherapy with a targeted antibody, allowing children with Fanconi anemia to receive stem cell transplants safely. The antibody, briquilimab, removes diseased stem cells without radiation, enabling nearly complete donor
