A new Colorado State University study of the interior U.S. West has found that tree ranges are generally contracting in response to climate change but not expanding into cooler, wetter climates—suggesting that forests are not regenerating fast enough to keep pace with climate change, wildfire, insects and disease.

In 1862, Charles Darwin predicted the existence of a moth with a long tongue based on a comet orchid's nectar spurs. This was confirmed in 1903 with the discovery of a long-tongued hawkmoth, illustrating morphological trait matching in nature.

A new study led by Prof. Tan Zhiliang from the Institute of Subtropical Agriculture of the Chinese Academy of Sciences has unveiled intricate coordination mechanisms between ruminal mucosal microbiota and host epithelial cells across developmental stages.

A recent study reveals that age plays a significant role in the outcomes of intermittent fasting. Researchers discovered that chronic intermittent fasting disrupted the development of insulin-producing beta cells in young mice. The findings raise concerns about potential risks for humans, especially teenagers.

Under-sea mountains are key locations for predators -- with 41 times more sharks than the open ocean, new research shows.

A team of Chinese scientists has used targeted gene editing to develop rice that produces coenzyme Q10 (CoQ10), a vital compound for human health.

An interdisciplinary research team from Leipzig University and the Saxon AI center ScaDS.AI has developed a novel approach that integrates artificial intelligence (AI) methods with biophysical modeling. This innovative strategy can be applied to the development of new therapeutics, such as antibodies and vaccines, including those for pandemic preparedness.

Understanding the behavior of tiny droplets in our cells could aid the search for new treatments. A team of Leiden researchers has developed a method to study how these droplets transition from liquid to solid. This change plays a role in various diseases, including neurodegenerative disorders like Alzheimer's and muscular dystrophy. The findings were published in Cell Reports Physical Science.

French customs officers seized nine dinosaur teeth last month from a courier truck transiting through the country from Spain on its way to Italy, they said on Friday.

Picture a horse running across an open field, the wind blowing his mane, his hooves stamping into the grassy knoll, eyes on the horizon.

Researchers have revealed new details about the CRISPR-Cas5-HNH/Cascade complex, a variant of the type I-E CRISPR-Cas system, providing insights into its DNA recognition and cleavage mechanisms.

A team of microbiologists, chemists and pharmaceutical specialists at Shandong University, Guangzhou Medical University, Second Military Medical University and Qingdao University, all in China, has developed an AI model that generates antimicrobial peptide structures for screening against treatment-resistant microbes.

While sharks might have a fearsome reputation, the chances of being bitten by one are incredibly low. In 2024, just 47 people were hurt in unprovoked shark attacks—the lowest level in almost 30 years.

In a study published in Nature Structural and Molecular Biology, scientists from the Department of Medical Biochemistry and Biophysics at Karolinska Institutet, have discovered that water molecules play a crucial role in helping proteins, specifically transcription factors, read and regulate the human genome.

Cells in the body have to move around in order to do their jobs. During development, for instance, cells are distributed to create and grow tissue. And in the event of an immune response, different cells are shuttled around. While this process, known as cell migration, is essential for health, it can also go awry and contribute to disease, including chronic inflammation, fibrotic diseases, and cancer metastasis.

Undersea mountains are key locations for predators—with 41 times more sharks than the open ocean, new research shows.

A team of veterinary surgeons performed cataract surgery on Thunder, a resident bald eagle at Moccasin Lake Nature Park in Clearwater, at a clinic in Brandon on Thursday.

Farmworker communities are protesting the California Department of Pesticide Regulation's proposal to limit the pesticide 1,3-dichloropropene, arguing the measures don't go far enough to protect against long-term cancer risks.
