Whether it's redfin pickerel in the Kennebec River or sturgeon in the Great Lakes, nearly one-third of freshwater fish species are facing possible extinction, threatening food supplies, ecosystems and outdoor recreation. As conservationists work to preserve these species, the
Antibiotics are medical marvels that have transformed once deadly bacterial infections into manageable conditions. But with a rise in antibiotic resistance that renders existing treatments ineffective, new agents are urgently needed. Scientists at Caltech and Princeton
The Great Unconformity is a major gap in Earth's geologic record. The missing layer between Precambrian and Cambrian rocks represents a gap of around a billion years of history. Among much debate surrounding the cause of the gap, a new study, published in the Proceedings of the
Mexico stands at a critical security crossroads following the confirmed death of Nemesio Oseguera Cervantes, known as El Mencho, the founder and leader of the Jalisco New Generation Cartel.
In physics, the classical "Hall effect," discovered in the late 19th century, describes how a transverse voltage is generated when an electric current is exposed to a perpendicular magnetic field. Simply put, the magnetic field causes the electrons, which are negatively

Biologists have long wondered why caribou are the only deer in the world in which females—like males—have antlers. A study of shed antlers collected from calving grounds in the Arctic National Wildlife Refuge provides a new answer. The study is published in the journal Ecology
If you've been following exoplanet research over the last couple of years, you've definitely heard of K2-18b. Located 124 light years away in the constellation Leo, it's attracted a lot of attention as it sits squarely in its red dwarf host star's habitable zone, and
As you read this, the screen is probably flashing over 240 times per second, yet, as a human, you won't notice this flickering light. However, to a fruit fly hovering above your head, the screen would represent a strobe light fit for an Ibiza rave. This is because the way
When deciding whether to invest in environmental projects, it's important to consider the economic value of any long-term benefits. Whether climate solutions (such as offshore wind power or solar farms) are recognized as valuable or worthless depends very much on which economic
A team of scientists from around the world has created the first system that can predict when and where extremely powerful solar storms, called superflares, are most likely to happen. These storms can disrupt power grids, communications, and satellites, and even pose dangers to
One of the best forms of heat relief is pretty simple: trees. In cities, as studies have documented, more tree cover lowers surface temperatures and heat-related health risks. However, as a new study led by MIT researchers shows, the amount of tree cover varies widely within
Eastern Canada has seen a rise in the number of hurricane- and near-hurricane strength events battering its maritime areas, with particularly violent storms in 2003 (Hurricane Juan), 2019 (Dorian) and 2022 (Fiona). While this seems to be a recent phenomenon, the region has
Beaver dams are critical to river health and a source of biodiversity. They create wetlands, slow water and improve water quality. They also reduce flood peaks and delay runoff. But beaver dams are often blamed when extreme rainstorms cause flooding—especially when they fail.
A study published in Ecological and Evolutionary Physiology reveals a surprising link between cellular aging markers and survival in black-legged kittiwakes (members of the gull family). In the work titled "Who's coming home? Shorter early-life telomeres predict return to the
Pesticides can harm aquatic ecosystems and human health, so scientists need to understand how they move from farm fields into streams. A management tool commonly implemented is riparian buffers—strips of vegetation, like shrubs or grasses, bordering streams—that the U.S.

Thunderstorms can generate weak electrical discharges on the plants underneath, but until now, they had never been observed in nature
Simon Fraser University researchers have uncovered fiberglass contamination in a key estuary on Vancouver Island, raising concerns about how an as-yet-overlooked contaminant could affect aquatic birds, marine life and coastal communities that rely on shellfish and seafood.
A key characteristic of modern human society is rapid urbanization, a process that can reshape natural environments and disrupt the habitats of many organisms. One widespread byproduct of urbanization is artificial light at night (ALAN), which has become one of the most
