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.

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 demonstrate how it could lead to new therapies for cervical cancer.

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 molecules when they collide, creating a hazardous environment that can also be dangerous to space probes and their instruments.

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.

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 are linked to moon phases yet few studies to date have looked at the connections between lunar phases and shark attacks.

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 electrons to minerals outside the cells.

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.

San Jose's trees are slowly vanishing.

The age of the oldest fossils in eastern Africa widely recognized as representing our species, Homo sapiens, has long been uncertain. Now, dating of a massive volcanic eruption in Ethiopia reveals they are much older than previously thought.

Scientists understand quite well how temperature affects electrical conductance in most everyday metals like copper or silver. But in recent years, researchers have turned their attention to a class of materials that do not seem to follow the traditional electrical rules. Understanding these so-called "strange metals" could provide fundamental insights into the quantum world, and potentially help scientists understand strange phenomena like high-temperature superconductivity.

Economic growth goes down when the number of wet days and days with extreme rainfall go up, a team of Potsdam scientists finds. Rich countries are most severely affected and herein the manufacturing and service sectors, according to their study now published as cover story in the renowned science journal Nature. The data analysis of more than 1,500 regions over the past 40 years shows a clear connection and suggests that intensified daily rainfall driven by climate-change from burning oil and coal will harm the global economy.

Certain groups in the U.S.—Blacks, Asians, Hispanics, Latinos, and low-income populations—are being exposed to higher levels of dangerous fine particulate air pollution (PM2.5) than other groups, according to new research from Harvard T.H. Chan School of Public Health.

Inside a bamboo culm in Thailand, researchers discovered the first case of a genus of tarantula that lives exclusively in bamboo stalks.

NASA's InSight lander is stable and sending health data from Mars to Earth after going into safe mode Friday, Jan. 7, following a large, regional dust storm that reduced the sunlight reaching its solar panels. In safe mode, a spacecraft suspends all but its essential functions.
