A powerful storm system bringing heavy snowfall was blowing into Colorado on Friday, a day after devastating wildfires fueled by hurricane-force winds destroyed hundreds of homes and forced tens of thousands to flee.

An endangered leopard captured in Iraq's mountainous north had its hind leg amputated on Friday following a trap-inflicted wound, an AFP photographer said.

The number of cougars spotted in Michigan's Upper Peninsula has risen over the years. But barriers to the big cats' eastern migration have so far kept them from establishing reproducing populations here.

On Tuesday, the EPA announced it approved a request that it study health impacts of dozens of "forever chemicals" industrial waste detected in the Cape Fear River. But that is misleading, say members of North Carolina environmental groups who filed a petition seeking the studies.

France has culled 600,000 to 650,000 chickens, ducks and other poultry over the past month, officials said Friday, in a race to contain a bird flu virus threatening to become the fourth major outbreak in the country since 2015.

Extreme weather in Alaska that has brought record high temperatures and torrential downpours has left authorities in the far northern US state warning of "Icemageddon".

The previously elusive methanediol molecule of importance to the organic, atmospheric science and astrochemistry communities has been synthetically produced for the first time by University of Hawaiʻi at Mānoa researchers. Their discovery and methods were published in Proceedings of the National Academy of Sciences on December 30.

Hundreds of homes are feared lost in fast-moving wildfires in the US state of Colorado, officials said Thursday, as flames tore through areas desiccated by a historic drought.

The summit of an underwater mountain, higher than Mount Kosciuszko, has been mapped for the first time by the Australian icebreaker Research and Supply Vessel (RSV) Nuyina.

Realizing the vision of culturing organs for use in life-saving transplantation procedures is still a long way off. However, the work of Prof. Jacob Hanna on stem cells is paving the way for this to become a reality.

A new study shows how cell membranes curve to create the "mouths" that allow the cells to consume things that surround them.

Natural evolution is a slow process that relies on the gradual accumulation of genetic mutations. In recent years, scientists have found ways to speed up the process on a small scale, allowing them to rapidly create new proteins and other molecules in their lab.

More hurricanes are likely to slam Connecticut and the region as the planet continues warming due to greenhouse gas emissions, according to a study led by Yale University researchers.

Nearly three months after an undersea pipeline spilled thousands of gallons of crude oil into the waters off Southern California, authorities have announced that coastal cleanup efforts are now complete.

Let's take a journey into the depths of the Earth, down through the crust and mantle nearly to the core. We'll use seismic waves to show the way, since they echo through the planet following an earthquake and reveal its internal structure like radar waves.

A tiger was shot dead at a Florida zoo after biting a cleaner who had put his arm through the fencing of its enclosure, law enforcement and local media said.

Iran on Thursday announced it launched a satellite carrier rocket bearing three devices into space, though it's unclear whether any of the objects entered orbit around the Earth.

A joint research team led by Prof. Husi Letu from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS) has developed a new dataset, East Asia-Pacific longwave/shortwave downward radiation at the surface data set (2016–2020), from the new generation geostationary satellite Himawari-8.

With the holiday season's soon ending, many retailers are preparing for consumer returns requesting either exchanges and/or refunds.

Astronomers have managed to link the properties of the inner planets of our solar system with our cosmic history: with the emergence of ring structures in the swirling disk of gas and dust in which these planets were formed. The rings are associated with basic physical properties such as the transition from an outer region where ice can form where water can only exist as water vapor. The...

Orchid hunting conjures images from the 1800s—explorers in mud-spattered khaki, traipsing through impenetrable jungle, overloaded with equipment: jars, bottles, bags and boxes, a gun (to shoot down tree-top orchids) and a magnifying glass. Things have changed a bit since then. You don't need to sail halfway around the world—and all you need is a camera or smartphone.

Has your home recently been overrun by tiny gray moths, flapping erratically around your kitchen? Spotted some suspicious webs in a cereal box? You might be sharing your dried food with pantry moths (Plodia interpunctella).

The publishing of several articles that reveal the vulnerability of farmed fish to the anisakis parasite has prompted the research group in Marine Zoology of the University of Valencia to experimentally assess the infective susceptibility of fish. The results from the ANITEST project, which just ended, show that in the improbable case that the parasite reaches farms, fish are not very susceptible...

Emily Setton removes the lid from a small, plastic dish on her lab bench. Within the clear, rectangular plate are half-circle wells containing hundreds of round beads about the color and size of couscous—the large kind.
