Elon Musk Launches the Robotaxi—Can Tesla’s Cybercab Share the Road with America’s Myth of the Highway?
For more than a century, cars have meant freedom, escape and self-reinvention to Americans. Now Tesla’s forthcoming Cybercab makes us ask whether we can have the romance of the open road without actually driving it
Student discovers widespread microplastic pollution in Appalachian streams and fish
When West Virginia University biology undergraduate student Isabella Tuzzio tested fish from central Appalachian streams, her research revealed microplastics in every fish she sampled.
Early humans survived in a range of extreme environments before global migration, study says
Humans are the only animal that lives in virtually every possible environment, from rainforests to deserts to tundra.
How archaeology can offer a blueprint for adapting to climate change
How does climate change affect the way humans organize themselves? How has it shaped the course of human evolution? An international team of scientists, including scientists from the Université de Montréal, think the key to answering those questions is to pay more attention to
Technology to enforce teen social media ban is 'effective,' trial says. But this is at odds with other evidence
Technologies to enforce the Australian government's social media ban for under 16s are "private, robust and effective." That's according to the preliminary findings of a federal government-commissioned trial that has nearly finished testing them.
Moth uses stars to navigate long distances, scientists discover
A species of Australian moth travels up to a thousand kilometers every summer using the stars to navigate, scientists said Wednesday, the first time this talent has been discovered in an invertebrate covering vast distances.
LLMs delve into online debates to create a detailed map of human beliefs
Large language models (LLMs), such as the model underpinning the functioning of the well-known conversational platform ChatGPT, have proved to be very promising for summarizing and generating written texts. However, they could also be interesting tools for conducting research
Antimicrobial resistance genes hitch rides on imported seafood
Colistin is a potent, last-resort antibiotic used only to treat people with dangerous, life-threatening bacterial infections that have developed resistance to other drugs. But it's not foolproof. Worldwide, resistance to colistin is spreading, further diminishing treatment
Rice University breakthrough keeps CO₂ electrolyzers running 50x longer
A Rice University team discovered that bubbling CO₂ through a mild acid dramatically improves the lifespan and efficiency of electrochemical devices that convert CO₂ into useful fuels. This simple trick prevents salt buildup—a major barrier to commercialization—by altering
What the Universe tried to hide: The 21-centimeter signal explained
Scientists are peering into the universe's mysterious Cosmic Dawn using the faint whispers of hydrogen radio waves emitted over 13 billion years ago. These signals, particularly the elusive 21-centimeter signal, offer rare insights into the masses and behavior of the universe’s
Breakthrough magnet design could transform MRI and magnetic levitation
Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works only with infinitely long magnets, they engineered innovative 3D magnet
Half of today’s jobs could vanish—Here’s how smart countries are future-proofing workers
AI is revolutionizing the job landscape, prompting nations worldwide to prepare their workforces for dramatic changes. A University of Georgia study evaluated 50 countries’ national AI strategies and found significant differences in how governments prioritize education and
HIV is surging in over-50s—But campaigns still target the young
HIV is surging among adults over 50 in sub-Saharan Africa, yet prevention and treatment campaigns still focus mainly on the young. New research reveals older adults face comparable or higher infection rates but remain largely invisible in HIV studies, which hampers progress
Zapping aging cells: The fast, label-free test that could transform research
Scientists in Tokyo have developed a groundbreaking, label-free method to identify aging human cells using electric fields. This new technique avoids the downsides of chemical tagging, which can distort results and slow research. By analyzing how cells move under alternating
Quantum breakthrough: ‘Magic states’ now easier, faster, and way less noisy
Quantum computing just got a significant boost thanks to researchers at the University of Osaka, who developed a much more efficient way to create "magic states"—a key component for fault-tolerant quantum computers. By pioneering a low-level, or "level-zero," distillation
FDA under fire: Data discrepancies uncovered in AstraZeneca approval trials
Fresh concerns have emerged about the platelet studies underpinning the FDA approval of ticagrelor, AstraZeneca's multibillion-dollar heart drug. A new BMJ investigation reveals data discrepancies, missing lab readings, and questions about the integrity of the trial process.
