If you've ever ordered food through DoorDash, Uber Eats or Instacart, you may have realized the person who delivers it isn't a salaried employee. They're gig workers—independent contractors who pick up delivery tasks through an app, get paid per delivery and have no guaranteed
This week, among a lot of other important findings, we learned that emperor cichlid fish have gaze sensitivity and dislike it if you look at them—or especially their children. England is looking for a solution to its 5-billion-liter water deficit. And a high-fiber diet isn't
A new pill, enlicitide, reduced LDL (“bad”) cholesterol by about 60% in a large clinical trial, matching the power of injectable therapies. Because it’s taken orally, it could overcome one of the biggest barriers keeping patients from using current treatments. Researchers say
A lactic acid bacterium isolated from kimchi may help promote the removal of nanoplastics from the body by binding to them in the intestine. Nanoplastics are ultrafine plastic particles measuring less than 1 micrometer that are generated during the degradation of larger plastic
Infectious disease experts say shots against meningococcal meningitis can be lifesaving during an outbreak, but U.S. regulators have attempted to roll back recommendations of such a vaccine for children
Researchers have discovered that cancer spread isn’t random—it follows a kind of biological “program.” By studying colon tumor cells, they identified gene patterns that signal whether a cancer is likely to metastasize. Their AI model, MangroveGS, can predict this risk with
Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked photonic crystals and adjusting their spacing with a tiny mechanical system, they can control how light’s “handedness” behaves. This allows the chip to
A routine quantum optics technique just revealed an extraordinary secret: entangled light can carry incredibly complex topological structures. Researchers found these hidden patterns reach up to 48 dimensions, offering a vast new “alphabet” for encoding quantum information.
Physicists have directly visualized the fundamental electronic building blocks of flat-band quantum materials, a class of systems in which electron motion is effectively quenched and strong interactions give rise to emergent phases of matter. In a study published in Nature
Editor in chief Nancy Shute discusses how science and armed conflict have been intertwined throughout history, from the Greeks in 400 B.C. to the use of tear gas in the protests across the United States as recently as a few months ago.
Damage to the blood-brain barrier is linked to immune changes and cognitive decline
Youth in foster care often experience family instability, which can disrupt the continuity of their relationships and social connections. Therefore, the strength and stability of their social support networks can play a critical role in shaping their lives.

A burst of unusual March heat is hitting the United States this week and into next, busting previous monthly heat records by wide margins. While heat is most acutely felt by people exposed to it, graphics and charts convey the scale of this extreme event. Temperatures in the
A newly discovered Triassic reptile from the UK looked more like a racing greyhound than a crocodile, built for speed on land. With long legs and a lightweight body, it hunted small animals in a dry, upland environment millions of years ago. Scientists identified it as a new
Scientists have uncovered the oldest direct evidence yet that Earth’s tectonic plates were on the move 3.5 billion years ago. By analyzing magnetic fingerprints in ancient rocks, they reconstructed how parts of the planet slowly drifted and even rotated over time. This
On Tuesday, CERN will transport antiprotons on a truck for the first time, testing the plan to deliver antimatter by road to research labs across Europe
Scientists have engineered probiotic bacteria to act as tumor-seeking drug factories. In mice, these bacteria infiltrated tumors and produced a cancer-fighting drug right where it was needed. This targeted approach could make treatments more effective and reduce side effects.
“Forever chemicals” may be affecting kids in ways that last a lifetime. A new study links early PFAS exposure to lower bone density during the teen years, especially in girls. Researchers also found that when exposure happens may play a key role. Reducing exposure during
New research led by James Cook University (JCU) emphasizes that the success of marine protected areas (MPAs) depends largely on understanding and influencing people's behaviors within their borders. The study demonstrates that effective conservation relies on compliance—a
Animals do all sorts of things to attract each other as potential mates. Many birds, for example, produce feathers with elaborate color patterns—from the iridescent plumage of many hummingbirds to the famously brilliant tail of a peacock. Charles Darwin, an early pioneer in the
Across the sciences, researchers are asking why so many scientists leave their fields. A new study from Virginia Tech suggests at least part of the answer may be surprisingly simple. Scientists who feel a stronger sense of belonging in their discipline are more likely to intend
Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed. This loss has been linked to heart disease, cancer, Alzheimer’s, and shorter lifespans. Researchers suspect Y-less cells may grow faster and disrupt
Most of Europe's original natural forests have been transformed for agriculture and managed forests producing energy, paper, and timber. The few remaining "old-growth" natural forests are relics of the past that illustrate how forests would have looked in the absence of human
New research from the University of East Anglia (UEA) reveals that King Harold's legendary 200-mile march to the Battle of Hastings in 1066 never happened. Instead, the journey was made largely by sea. The findings overturn one of the most iconic stories in English history,
Two University of Victoria (UVic) geologists have integrated field geology with statistical modeling to give scientists a new view of the chemical reactions happening on ocean floors billions of years ago. The revised picture shows that big changes in the carbon cycle were
The building blocks of proteins, amino acids, are essential for all living things. Twenty different amino acids build the thousands of proteins that carry out biological tasks. While some are made naturally in our bodies, others are absorbed through the food we eat.
For more than a century, condensed matter physics has grappled with one of its greatest unsolved challenges: how to build superconductors that operate at room temperature and transmit electricity with no loss. Now, in a paper published in Nature, a team of Harvard physicists
Chosen families are evolving but remain a cherished—and vital—lifeline for many. Mention "communal living" and the image that may spring to mind is the free-love, back-to-the-earth hippy communes of the 1960s, complete with bandannas and fringed suede vests. But communal living
The high-performance semiconductor devices powering smartphone displays, AI computing, EV batteries and more are increasingly incorporating 2D materials to overcome silicon's scaling limits. To optimize these technologies, a University of Michigan Engineering team developed a
When most people think about corals, they imagine a tropical reef with crystal blue water, teeming with colorful fish. But, in the depths of the cold, murky Gulf of Maine, deep-sea corals thrive, feasting on a steady supply of organic matter raining down from the surface ocean.
For half the world's population, the water in their drinking glasses comes from below them. Groundwater also supplies 40% of global irrigation projects. Alarmingly, more than a third of the planet's aquifers, or groundwater basins, are dropping. Declining water tables leave
A new Murdoch University study has found that cold-blooded animals (ectotherms) are unable to adjust physiologically to daily temperature fluctuations, a limitation that could leave them increasingly vulnerable as climate change drives even greater temperature variability.
Climate warming can increase plant growth in permafrost regions by lengthening the growing season, speeding up plant metabolic processes, and allowing deeper root penetration as permafrost thaws. However, the capacity for additional vegetation to offset the carbon released
