Global fish production and consumption have hit new heights, according to the United Nations. People worldwide are consuming much more fish per capita, and more than 23 million people now work in the aquaculture industry. That booming business is putting pressure on the world's
New research published at COP31 issues a stark warning about the health of the frozen parts of the planet—ice sheets, mountain glaciers, sea ice, permafrost and snow cover—known as the cryosphere. The study, published in Science, finds that human-driven climate change is
A star's explosive demise has added a shiny new feature to NGC 1433, a barred spiral galaxy approximately 50 million light-years away in the southern constellation Horologium (the Pendulum Clock). New images of supernova SN 2026ahvu from the U.S. Department of Energy–fabricated

Wheat researchers at South Dakota State University are perfecting an AI-powered web application designed to speed the work of wheat breeders and equip farmers with a more accurate tool for making decisions.
Left to their own devices, babies in the womb would suck their mothers dry. A developing baby benefits from taking as many essential nutrients as possible, but evolutionary theory predicts that to survive pregnancy, mothers need to keep some of these nutrients for themselves.
Earlier this week, the U.S. Department of Agriculture's Animal and Plant Health Inspection Service (USDA's APHIS) announced the first detection of H5N1 avian flu in a dairy herd in Oregon.

While young people are constantly exposed to news about climate change, their resulting anxiety does not always translate into environmental action. A new study published in Climate reveals that the relationship between climate distress and climate action is highly complex.
The Rhine, as the boundary between Western and Central Europe, appears to be a constant feature of European history. As early as the late fourth and early third millennia B.C., the traces of human activity east and west of the river differed. Archaeologists have long concluded
Bioprinting uses living cells and molecular signals to produce biological tissues and even whole organs, building them layer by layer in the lab. To keep the bioink, or blend of cells and materials that power this printing, correctly aligned to grow a target tissue, researchers
Humor is becoming an increasingly popular feature of job advertisements, with employers using it to stand out, capture attention and attract potential candidates.
If people ever think about cleaning up space debris, they typically think of something equivalent to a giant garbage truck in the sky, collecting lost astronaut tools and dead satellites, then hauling them back down to Earth to be deposited in a landfill. But dealing with space
A new comprehensive study by researchers at the University of Hawaiʻi (UH) at Mānoa Climate Resilience Collaborative reveals that traditional sea-level rise models, which account only for rising ocean waters, drastically underestimate the true threat to coastal infrastructure
Ask any reptile lover where to find a cold-blooded creature, and chances are they will point to a rocky outcrop.
What's the best way to protect ourselves against climate change? The default is to reach for concrete and steel to build seawalls, dikes, dams and drainage systems. These can work. But they are expensive and inflexible. There's another, much cheaper option which gets vastly
When amphibians and reptiles get an infection, they sometimes raise their body temperature above its usual level by moving to a warmer environment. This well-documented behavioral response is known as behavioral fever.
The ESA's Euclid has already teased us with some early results. In the past, it's given us a small image covering 60 square degrees of the sky, created with a few days of observations. Those images showed individual targets from the Horsehead Nebula to the Perseus cluster of
It officially opens next month The post Trail Cameras Show Coyotes Using the World’s Largest Wildlife Crossing appeared first on Nautilus .
A new study reveals that viral infections may leave behind hidden damage to the immune system long after symptoms disappear. Researchers found that mice recovering from an acute infection experienced lasting changes to their spleens and weakened immune responses, potentially
A study of more than 750,000 pregnancies found that early exposure to Ozempic, Wegovy, and similar drugs was not linked to increased pregnancy complications when used for weight loss, but was associated with a higher risk of premature birth when prescribed for diabetes. The
Vancomycin-resistant Enterococcus faecium is listed by the World Health Organization as one of the highest-priority bacteria in its 2024 Bacterial Priority Pathogens List, ahead of MRSA, due to its ability to transfer resistance genes between humans, animals and the environment.
Businesses and institutions in just 6% of Montreal's mapped area account for about 100,000 metric tons (110,000 tons) of food waste sent to landfill each year—half of the total amount from nonhousehold sources in the city as a whole, McGill University researchers found. Food
A major study of nearly 1,900 older adults suggests that stopping statins after age 70 may be relatively safe in the short term for people who have never experienced a heart attack or stroke. However, a higher rate of serious cardiovascular events or death during longer
A new national database developed at the University of Michigan shows that none of the top 99 public transportation systems in the United States are easy for people with disabilities to use in four key areas of accommodation and accessibility.
Why do some volcanoes erupt with spectacular lava fountains while others release lava more quietly? Scientists have discovered that a hidden effect of extreme heat inside magma may help explain the difference. Experiments revealed that superheated magma can delay crystal
Lumina, a huge computer model laden with complex astrophysics, is giving scientists a breathtaking virtual view of the young universe
Our uniquely human walking style comes with evolutionary benefits—but also a cost
A mysterious force driving the expansion of the Universe may have undergone a dramatic reversal billions of years ago. Scientists exploring an overlooked branch of an alternative gravity theory discovered that dark energy could have switched from negative to positive roughly
China's one-child policy is widely considered one of the most stringent public policies in modern history. Yet researchers have long debated how much it actually contributed to the country's dramatic fertility decline.
The first consensus guidelines on stuttering, released this summer, are throwing new light on an ancient condition
Elon Musk's SpaceX was poised Friday to carry out its latest test of the world's biggest and most powerful rocket, the Starship, with plans for a groundbreaking "catch" of the spaceship following a day in orbit.
Wildfires that consumed vast swaths of Indonesia this year were driven largely by a strong El Niño, fueled by climate change and decades of natural landscape destruction, researchers said Friday.

Scientists have discovered a faster way to identify diamond-based materials that could power quantum computers and sensors at room temperature. The breakthrough has already revealed promising new quantum building blocks that could help unlock computing capabilities far beyond
Discussing racism with children can seem daunting to parents, caregivers and educators for several reasons. Often, it can feel uncomfortable talking about people's differences; conversations about racism reveal implicit biases and, for some, immense privilege.
Quantum computers have the potential to perform calculations more quickly than supercomputers, but they could be even faster and more energy-efficient if they were built with photons as their basic units, called qubits.
If we want big things in space, we'll have to build and assemble them there. Rocket fairings are not large enough to accommodate the large things we want to have in space. Not only that, but the stubborn rocket equation refuses to bend itself to our desires.
As the major powers and the private companies go full tilt with their plans to develop infrastructure and extract resources on the moon, the questions around environmental protection, international regulation and who benefits all come into play. Vilnius University Institute of
