Measuring how much antimicrobial medication is given to food animals is key to understanding how to slow antimicrobial resistance, when dangerous microbes get so used to antimicrobials that they evolve stronger defenses against them. However, measuring the actual antimicrobial use in animals on a large scale is still a logistical challenge. Because data on antimicrobial sales for use in food...

Scientists from Wageningen University and Research (WUR) and Indiana University have discovered that the increasing irrelevance of factual truth in public discourse is part of a groundswell trend that started decades ago.

A couple walking on a North Carolina beach made a rare discovery that could help researchers solve mysteries from long ago.

Megaripples, intermediate-scale bedforms caused by the action of the wind, have been studied extensively and thought to be largely inactive relics of past climates, save for a few exceptions. A new paper by Planetary Science Institute Research Scientist Matthew Chojnacki shows that abundant megaripple populations were identified across the north polar region of Mars and were found to be migrating...

A new University of British Columbia (UBC)-led study looking into the impacts that large industrial farming has on biodiversity found that increased farm size causes a decline in bird diversity.

Many lessons learned in life are learned from trees. Stand firm. Good things take time. Bend, don't break. But metaphors aside, our stately arboreal neighbors offer a wealth of scientific wisdom—and we have a lot to learn.

A solar eclipse over the Arctic created changes in auroras in both of Earth's hemispheres due to connections through the planet's magnetic field, according to a new study. The new work could help scientists predict changes in the near-Earth environment that can interfere with satellite communication.

Black men are disproportionately impacted by injuries in the United States. This disparity is glaring given that injury is one of the top ten causes of death. Data show that injured Black men from disadvantaged neighborhoods experience higher injury mortality, years of life-expectancy loss, and psychological symptoms that persist after initial wounds have been treated.

The United States has probably played a major and previously underestimated role in the trafficking of tiger parts, according to a new study. The research points to San Francisco, Dallas, and Atlanta as the main entry hotspots for these illegal products.

Using the 4.1-meter SOAR Telescope in Chile, astronomers have discovered the first example of a binary system where a star in the process of becoming a white dwarf is orbiting a neutron star that has just finished turning into a rapidly spinning pulsar. The pair, originally detected by the Fermi Gamma-ray Space Telescope, is a "missing link" in the evolution of such binary systems.

Understanding how cells die is key to developing new treatments for many diseases, whether the goal is to make cancer cells die or keep healthy cells alive in the face of other illnesses, such as massive infections or strokes. Two new studies from Washington University School of Medicine in St. Louis have identified a previously unrecognized pathway of cell death—named lysoptosis—and...

Planets like Earth, Jupiter and Saturn, with global magnetic fields of their own, are surrounded by so-called radiation belts: Trapped in the magnetic field, fast moving charged particles such as electrons, protons, and heavier ions whiz aroun, thus forming the invisible, torus-shaped radiation belts. With their high velocities reaching almost the speed of light, the particles can ionize other...

Eyes are crucial players in the evolution of organisms. They allow an animal to find food, a mate, potential prey, to avoid predators and aid in regulating the internal clock by differentiating day from night. Eyes are also delicate features that tend to be not well preserved in fossil crustaceans.

Male mosquitoes beat their wings faster when swarming at sunset to better detect females and increase their chance of reproducing, finds a novel study led by UCL scientists.

Microplastics can deposit and linger within riverbeds for as long as seven years before washing into the ocean, a new study has found.

Scientists are honing the traits of speed, strength and near invulnerability in an important food crop that, much like a superhero, will help protect the vulnerable.

Russian animal rescuers said Wednesday they were fighting for the life of an Amur tiger cub who had been found dying from exhaustion and frostbite in the country's far east.

New research from LSU and the University of Florida suggests that more shark attacks occur during fuller phases of the moon. While the exact cause remains unclear, the researchers found that more shark attacks than average occur during periods of higher lunar illumination and fewer attacks than average occur during periods of lower illumination. Many different types of animals show behaviors that...

Every living thing requires energy. This is also true of microorganisms. Energy is frequently generated in the cells by respiration, that is, by the combustion of organic compounds—in other words, food. During this process, electrons are released, which the microorganisms then need to get rid of. In the absence of oxygen, microorganisms can use other methods to do so, including transporting the...

Australian and European researchers have discovered a genetic element in a common wheat pathogen with potential to help streamline breeding for disease-resistant wheat varieties that are better suited to Australian conditions.

New research has shown how current red squirrel conservation strategies in the UK and Ireland, that favor non-native conifer plantations, are likely to negatively impact red squirrels.

Florida, the "Sunshine State," is rapidly increasing installation of utility-scale solar energy (USSE) facilities to combat carbon emissions and climate change. However, the expansion of renewable energy may come with environmental tradeoffs. Reducing the energy industry's carbon footprint is impeding a large carnivore's paw-print.  

Nearly three years ago University of California San Diego researchers announced the world's first CRISPR-Cas9 genetic editing-based approach to controlling inheritance in mammals.

The results of a comprehensive search for a background of ultra-low frequency gravitational waves has been announced by an international team of astronomers including scientists from the Institute for Gravitational Wave Astronomy at the University of Birmingham.
