The United States government is rolling back conservation policies in a way that demonstrably risks accelerating already at-risk coral reefs around its island territory, Guam, in the Pacific Ocean. Part of the issue is the way the Endangered Species Act (ESA) is defined.
Separated by an ocean and more than a decade, innovative experiments with 31 tin isotopes having either a surplus or shortage of neutrons show how neutrons influence nuclear stability and element formation. The experiments, conducted between 2002 and 2012 at Oak Ridge National
In 2024, 38 Australian women were murdered by a partner or ex-partner. Thankfully, new data show the number of women killed by intimate partners has reduced to 32 over the most recent reporting period. The annual rate to June 2025 was among the lowest on record.
The profession of journalism is facing dual challenges of lost trust and relevance. A research project among educators, students, journalists and communities in six states has found that pairing student journalists with communities through structured conversation can help to
The tiny shell protecting the HIV virus resembles a slightly rounded ice cream cone, but there is nothing sweet about it. More than 40 million people worldwide live with AIDS because of this virus, and treatments must continually evolve as HIV mutates. During the acute stage of
Why do some systems collapse suddenly after what seems like a minor disturbance? A single transmission line failure can cascade into widespread blackouts. A delayed shipment can ripple through a global supply chain, emptying store shelves far from the original disruption. A
Britain's landscape is highly fragmented by roads, with researchers from Cardiff University finding that more than 70% of the UK's roadless areas are smaller than 1 km2. The researchers say that more than 60% of roadless patches in the UK are smaller than the typical area many
A new study published in the Journal of Climate reveals how surface warming in Antarctica, particularly over the Antarctic Peninsula, is significantly altering the stability of the lowest layers of the atmosphere.
New research shows that maintaining and adopting proposed marine protected areas (MPAs) in the Southern Ocean could almost double the protection of genetic hotspots from 28% to about 54%. These actions would stave off an otherwise high likelihood of ecosystem collapse in the
An earthquake typically sets off ruptures that ripple out from its underground origins. But on rare occasions, seismologists have observed quakes that reverse course, further shaking up areas that they passed through only seconds before. These "boomerang" earthquakes often
A research team led by Professor Tae-Woo Lee has developed a technology to mass produce ultra-high color purity perovskite nanocrystals (PeNCs), the core material for next-generation displays, without the need for high temperature, vacuum, or specialized gas facilities. This
Due to climate change, extreme weather events such as flooding are expected to increase in Germany in the future. This poses hidden risks to the health care system that have hardly been the focus of resilience planning to date: restrictions on access to hospitals and the supply
Up to 30% of bird diversity hotspots, places where large numbers of different bird species occur, in the western United States face threats from high-severity wildfires in the future that could eliminate critical forest habitats, according to research published in the journal
Birds currently inhabiting many territories across Africa, Latin America and Asia are, on average, considerably smaller than those that predominated in 1940. This is the conclusion of an international study led by the Institute of Environmental Science and Technology at the
In the everyday world, governed by classical physics, the concept of equilibrium reigns. If you put a drop of ink into water, it will eventually evenly mix. If you put a glass of ice water on the kitchen table, it will eventually melt and become room temperature. That concept
Researchers at the University of Oklahoma have developed new hybrid materials that challenge conventional thinking about how light-emitting compounds work and could advance the field of fast radiation detection. The research, published in the Journal of the American Chemical

Record warmth followed by a huge snowfall led to the recent avalanche that killed at least eight skiers
An ecosystem is not a still life. Even where everything looks stable—a woodland, a lake, the soil—the internal "bookkeeping" keeps changing: how many individuals belong to which species, and for how long. Some populations expand, others crash. That dynamism is part of what we
In a paper published in the journal Small, a team of physicists from IISER Pune have developed tiny electronic devices from a special semiconductor material called bismuth oxyselenide (Bi2O2Se). This development has potential applications in future flexible smartphones,
By applying new methods of machine learning to quantum chemistry research, Heidelberg University scientists have made significant strides in computational chemistry. They have achieved a major breakthrough toward solving a decades-old dilemma in quantum chemistry: the precise
Despite rare earth elements' importance in manufacturing cell phones, magnets and a host of other consumer and commercial electronics, the lack of a sustainable, environmentally friendly approach to obtaining these metals has led to a global shortage, according to Amir Sheikhi,
Ion channels are narrow passageways that play a pivotal role in many biological processes. To model how ions move through these tight spaces, pores need to be fabricated at very small length scales. The narrowest regions of ion channels can be just a few angstroms wide, about
In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma that viruses lack protein synthesis machinery, and blurs the line between
For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its limits. In a perspective article published in the journal Genetics, an
Violence and harassment in Canadian schools have reached such crisis levels that these public institutions should be categorized as hazardous workplaces, says a national report conducted by researchers in the School of Psychology and the Department of Criminology at the
Researchers at Case Western Reserve University have discovered a way to breach one of cancer's most stubborn defenses: the impenetrable fortress that solid tumors build around themselves.
Corralling a wild rhinoceros into a small chute to give it eyedrops might seem like a crazy plan. But if it's crazy and it works, then it's not crazy.

Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan. Instead, order emerges on its own from countless interactions between molecules that are constantly moving and rearranging. One of the most striking
Scientists have captured footage of a sleeper shark farther south than ever before, suggesting this Antarctic ocean is not shark-free
Proteins often function in pairs or groups, concealing their internal connection points and making it difficult for scientists to study their individual units without altering their natural structure. In a study published in the Journal of the American Chemical Society,
Scientists are proposing to build a laser in a crater on the moon to help future lunar missions land safely in the dark and find their way around. This ultra-stable light source could also help us keep time more accurately, as they explain in a paper available on the arXiv
The Antarctic ice sheet does not behave as one single tipping element, but as a set of interacting basins with different critical thresholds. This is the finding of a new study by the Potsdam Institute for Climate Impact Research (PIK) and the Max Planck Institute of
Radioactive cesium ions, due to their high-water solubility, pose a serious threat to human health and the environment. Conventional adsorbents such as Prussian blue (PB), although effective for cesium removal, often involve complex fabrication and high operational costs.
About 56 million years ago, Europe and North America began pulling apart to form what became the ever-expanding North Atlantic Ocean. Vast amounts of molten rock from Earth's mantle reached the ocean floor as the crust stretched and thinned, creating a volcanic, rifted margin
A new study finds entrepreneurs become more committed to their business ventures when they are told they will fail, increasing their efforts to make those businesses successful. "Most entrepreneurs—people who start their own businesses—actually identify with the business
