When you think of outer space, you're likely picturing stars, planets and moons. But much of space is filled with clouds of gas, plasma and stardust—known as interstellar clouds.
As debate intensifies over data center construction and how to regulate artificial intelligence (AI), a new nationally representative survey finds that Americans are broadly pessimistic about the impact of AI and want more government action to regulate the technology.
Last night, Labor unveiled a budget designed to tackle intergenerational equity in Australia through bold tax reform. It comes at a time when politics is consumed with the international shocks created by US President Donald Trump, whether through chaotic tariff announcements or
Researchers at the Technion have discovered how changes in genetic regulatory sequences can lead to alterations in the form and structure of animals—even when genetic regulatory systems are stable and resistant to change. The study, published in Science Advances, was led by Dr.
When third-year veterinary students at Cummings School of Veterinary Medicine at Tufts University step into the operating room to undertake their inaugural surgery, the energy in the room is palpable: there's excitement, but also nerves.
As modern technologies shrink to the nanoscale, surfaces increasingly dictate how materials deform, yield, and fail. Yet probing this regime has long been hindered by the challenge of preparing and controlling surfaces with true atomic precision, particularly at the outermost
Geological faults hold many secrets that may help us answer important questions about the nature of our planet and what really happens deep underground. One of the biggest mysteries lies within the Atotsugawa Fault System in Japan. What makes the area unusual is that, despite
When inorganic nanoparticles come together, their optical, electronic, and magnetic properties depend strongly on how they are arranged. Being able to reorganize these arrangements in a controlled way could therefore provide a powerful method for tuning material properties.
Describing new species can take decades. But scientists are working to identify new ways to speed up our understanding of this hidden biodiversity. By looking at the genetic data of thousands of beetle species, our researchers are able to reveal the true breadth of tropical
Government departments and other public bodies in the UK must consider requests to release information about AI-produced content, regulators have confirmed. The move follows a successful request by New Scientist for the release of a minister's ChatGPT logs
Medications are designed to treat diseased tissues while sparing healthy ones, often by attaching the drug to something that helps guide it directly to its target. But drugs also need time to work, which means they need to stay near the diseased tissues long enough.
More than 500 million years ago, during what is known as the Cambrian period, the seas and oceans on Earth were filled with a myriad of marine animals, many of which have now become extinct. This evolutionary burst in new forms of life, referred to as the Cambrian explosion,
People exposed to the Andes strain of the hantavirus may not develop symptoms for up to 42 days, a delay that makes tracing infections more difficult
With millions of people now using GLP-1 drugs such as Wegovy and Zepbound, scientists are racing to find ways to help people retain their weight loss after they stop taking the medication
Long-held assumptions tell us that atoms with the same number of protons, neutrons and electrons are indistinguishable, but one physicist wants to put this idea to the test
Insulators are materials in which electrons cannot move freely. Past theoretical studies predicted the existence of an unusual insulating state dubbed obstructed atomic insulator (OAI), in which electrons are localized inside a crystal, while their centers of charge lie in
Are we really falling short on protein—or is the high-protein craze overblown?
Tropical forests store more than 60% of the world's vegetation biomass and are among the most important ecosystems for regulating the global carbon cycle and climate. However, their regulatory role is greatly influenced by the forests' carbon residence time—how long carbon
In a forest of pine and eucalyptus trees in central Portugal, chainsaws and diggers hum away clearing paths blocked by trees uprooted in winter storms, but the threat now is a high risk of summer fires.

It's autumn in the Southern Hemisphere, which means it's fog season in the Victorian Alps. NASA's Terra satellite captured this view of morning fog filling valleys in several national parks across the mountains of eastern Victoria in May.
Archaeologists have found something unexpected inside a 1,600-year-old Roman-era Egyptian mummy: a fragment of Homer's Iliad. It wasn't placed beside the body, but inside the mummy's abdomen. But the real surprise isn't just where the fragment was found. It's how it got there.
Scientists at UBC Okanagan have uncovered how plants produce mitraphylline, a rare natural compound with promising anti cancer potential. The team identified two enzymes that work together to build the molecule’s unusual twisted structure, solving a mystery that had puzzled
Scientists at the University of Maryland, Baltimore County, have uncovered a crucial trick used by enteroviruses—the group behind diseases like polio, myocarditis, encephalitis, and even the common cold—to reproduce inside human cells. The team captured, in unprecedented
Researchers found a new way to kill harmful “zombie” cells that linger after chemotherapy and help cancers become more aggressive. These senescent cells survive by relying on a protective protein called GPX4, even while sitting on the edge of a deadly iron-triggered collapse.
Iodine deficiency is often seen as a problem of the past, but this isn't entirely true. During the 20th century, the iodization of salt became one of the most effective public health interventions for preventing conditions caused by a lack of this mineral, including goiter
Ganymede, Jupiter's largest moon, is also the solar system's largest satellite, even larger than the planet Mercury. It is also the only celestial body aside from Earth (and the gas giants) to have an intrinsic magnetic field. As if this didn't make the icy body interesting
Gravitational wave researchers working on the world's most sensitive scientific instruments have found a way to tune their detectors using a process akin to the pitch-correction used in music production.
