A new graph-theoretic framework provides a unified description of atom-light interactions across regimes ranging from weak to deep-strong coupling.
Hurricane Polo is expected to make landfall Monday in a small town on Mexico's Pacific coast, where authorities expect heavy rain and severe damage.
Indigenous workers in Australia earn 15.9% less per hour on average than all workers—or 84 cents for every $1 earned by non-Indigenous people—our research found.

In a new study published in Physical Review Letters, researchers have shown that magnetic order can survive weak quantum fluctuations in disordered magnets that lack an energy gap. The work establishes robust ferromagnetism in the two-dimensional random-bond quantum Ising model, confirming a longstanding conjecture in quantum statistical mechanics.
SpaceX launched its enormous Starship toward orbit for the first time Monday, aiming for six full laps around Earth to prove its readiness for NASA's Artemis moon program.

Tiny, striped zebrafish are helping scientists trace how a gene linked to albinism influences eye development, work that may ultimately help explain some of the vision problems experienced by people with the condition and guide the search for new treatments.

New international best practice guidance, co-written at ANSTO, sets out how to measure where nanoparticles like titanium dioxide end up in the body and how long they remain. The guidance has been shared by the Organization for Economic Co-operation and Development (OECD), a forum and knowledge hub for data, analysis and best practices in public policy.

In the 1960s, a miner working at a mineral extraction site in Jebel Irhoud, Morocco, struck something far more valuable than any mineral in the area: a skull with distinctly humanlike features. After an initial examination, archaeologists excavated further and uncovered more remains, which they estimated to be around 40,000 years old. They identified the main skull as an African Neanderthal and na

Paying a steeper price for a subscription service can trigger a familiar impulse: You want to get your money's worth. For companies selling AI tools, cloud computing and other digital services, that can complicate a basic pricing strategy. Raising prices may keep some customers from signing up, but those who do pay may be motivated to use the service more.

From the 13th to the 16th century, herring from the Sound—the strait in the Baltic Sea between Denmark and Sweden—was one of northern Europe's most important trade goods. Salted herring from the so-called Skanör-Falsterbo fishery fed large parts of Europe. Around 1570, however, the fishery collapsed rapidly, with far-reaching consequences for trade, politics and society. It took almost 400 years,

When light or sound bounces around inside an oddly shaped room, its reflections can quickly become difficult to predict. But new research led by scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) shows that waves can behave very differently when they travel through a special class of materials.

RNA vaccines, which have proved effective against COVID-19, are now being developed for many other diseases, including cancer. One drawback is that they require ultracold storage, but MIT researchers have found a promising way to overcome that limitation.
Three years after its first test flight, SpaceX's Starship rocket will attempt Monday to enter Earth orbit, a key step in developing the massive launch vehicle for future missions to the moon and Mars.
For weeks, Indonesia has been battling fires that have burned vast swaths of forest and peat ecosystems, causing toxic haze to blanket parts of the country, Malaysia and Singapore.

Weather forecasts in the Southern Hemisphere (SH) are generally less accurate than those in the Northern Hemisphere because Antarctica and the surrounding Southern Ocean have relatively few weather observations. With limited information about atmospheric conditions in one of the world's most remote regions, forecasting models often struggle to predict the movement of weather systems. This is espec

Bioimaging technologies, such as fluorescence imaging (FI) and magnetic resonance imaging (MRI), are powerful tools in basic research and clinical medicine. But they have drawbacks. FI allows researchers to visualize cells and other biological processes at high resolution, but it lacks imaging depth. MRI can capture images deep within the body, but it lacks the single-cell resolution provided by F

Farmers used to sniff their soil to gauge how healthy it was. According to ecologist Rosa Boone, you can deduce a great deal from its smell: "The fungi and bacteria present in the soil are important for soil health and are responsible for the soil's smell." Boone discovered that the smell of soil can be captured and analyzed in the lab, providing insights into these microbial communities. "Monitor

Even if industry rapidly becomes more sustainable, households will still need to change their lifestyles to meet climate targets. Industrial ecologist Stephanie Cap warns that households cannot do this alone: Businesses and governments must create the conditions to make these changes possible. Cap defends her dissertation titled "Everything Must Change: 1.5°C decarbonisation scenarios across indus

How are species boundaries maintained in the face of environmental disturbance? This is not only a fundamental question in evolutionary biology but also an increasingly important one as human activities and climate change alter habitats and bring previously separated species into contact.

When we think of a volcanic eruption, rivers of glowing lava or giant columns of ash come to mind. But beneath Earth's surface, a more complex story is unfolding. Magma deep within volcanoes is more than molten rock. It is a thick mixture of melted rock and solid mineral crystals known as "magma mush". To picture it, imagine a semi-frozen granita: a slushy blend of solid ice crystals suspended in

When Marineland Canada in Niagara Falls, Ontario, closed in September 2024, it had no regular income to support the care of the 30 belugas and four dolphins housed there. To ensure their welfare, the Association of Zoos and Aquariums led an international effort to relocate the animals to the United States and Spain.

Bionic Reading is a method of bolding certain letters in words that is purported to facilitate reading speed and comprehension. The idea is that guiding the eyes to focus on highlighted initial letters lets the brain complete the word. But does steering someone's gaze actually help them read?

Agri-photovoltaics combines electricity generation and agriculture on the same land—to ensure this works well in the long term, it is worth taking a closer look at the soil. Researchers at the Leibniz Centre for Agricultural Landscape Research (ZALF) have, for the first time, measured how the construction phase of agri-photovoltaic installations affects soil structure.

Moral language—words and phrases that express ideas about right and wrong, virtues, fairness, harm and social obligations—is widely used in social media posts and other online content. Posts containing moral language sometimes spread quickly and attract a lot of attention on social media, yet whether moral language is always linked to greater user engagement remains unclear.

Industrial activities such as textile manufacturing, paper production, leather processing and food processing can generate wastewater containing synthetic dyes. Because many synthetic dyes are chemically stable, difficult to biodegrade and environmentally persistent, their release into waterways can pose risks to aquatic ecosystems and human health.

Astronomers have identified what may be the first example of a new class of radio galaxy, one whose central black hole appears to have launched powerful jets on four separate occasions. High-resolution observations with the upgraded Giant Metrewave Radio Telescope (GMRT), combined with data from MeerKAT and the Very Large Array, reveal four pairs of radio structures arranged symmetrically around t

Chemosynthetic bacteria have been documented in various marine environments and in association with invertebrate hosts such as annelid worms and mollusks, but their presence in fish appears to be a new discovery. The findings show that fish gills host a complex and specialized microbiome that is not yet well understood but could play an important role in fish metabolism, immunity and health.
Heavy rain and strong winds battered the northeastern United States on Sunday as an unusually powerful autumn storm intensified, leaving tens of thousands without power. U.S. media reported one person dead.
