The Trump administration has canceled plans to open tens of thousands of acres for oil and gas drilling near three national parks in Utah next month, a victory for environmentalists and residents angered by its proposal.

Heavier mixed-breed dogs have higher health risks if neutered or spayed early, according to a new study from researchers at the University of California, Davis. The study found mixed-breed dogs weighing more than 44 pounds as adults are at higher risk for one or more joint disorders if neutered before 1 year of age. Dogs weighing up to 43 pounds had no increased risk for joint problems. The study...

"I'm fascinated with life, and that's why I want to break it."

As levels of atmospheric carbon dioxide continue to climb, scientists are looking for new ways of breaking down CO2 molecules to make useful carbon-based fuels, chemicals and other products. Now, a team of Brown University researchers has found a way to fine-tune a copper catalyst to produce complex hydrocarbons—known as C2-plus products—from CO2 with remarkable efficiency.

To judge the overall effectiveness of cover crops and choose those offering the most ecosystem services, agricultural scientists must consider the plants' roots as well as above-ground biomass, according to Penn State researchers who tested the characteristics of cover crop roots in three monocultures and one mixture.

Chemists at Scripps Research have efficiently created three families of complex, oxygen-containing molecules that are normally obtainable only from plants.

As the uncertainty around reopening college and university campuses this fall continues, those who work, study, teach and conduct research are navigating the uncertain terrain of the "new normal." They are balancing physical distancing and other COVID-19 prevention practices with productivity, creating home workspaces and mastering communications and teamwork across time and space.

If we can harness it, quantum technology promises fantastic new possibilities. But first, scientists need to coax quantum systems to stay yoked for longer than a few millionths of a second.

Researchers have designed an off-grid, low-cost modular energy source that can efficiently produce power at night. The system uses commercially available technology and could eventually help meet the need for nighttime lighting in urban areas or provide lighting in developing countries.

North Carolina State University researchers have demonstrated a new technique for creating ultrasound images. The new approach is substantially simpler than existing techniques and could significantly drive down technology costs.

Researchers at MIPT Laboratory of Terahertz Spectroscopy together with their Russian and international colleagues discovered a new phase of nanoconfined water; separate water molecules that are confined within nanocavities formed by ions of cordierite crystal lattice. The first reliable experimental observation of a phase transition in a network of dipole-dipole coupled water molecules is, in and...

Viruses multiply by injecting their DNA into a host cell. Once it enters the intracellular fluid, this foreign material triggers a defense mechanism known as the cGAS-STING pathway. The protein cyclic GMP-AMP Synthase (cGAS), which is also found inside the fluid, binds to the invading DNA to create a new molecule. This, in turn, binds to another protein called Stimulator of Interferon Genes...

Central America is one of the most diverse floristic regions in the world, but a lack of comprehensive plant records and knowledge of its endangered, endemic tree species impedes conservation work.

The tenth named tropical cyclone of the Atlantic Ocean hurricane season was named today, Aug. 13, after NASA-NOAA's Suomi NPP satellite provided a nighttime image of the storm.

A Canadian-Finnish collaboration has led to the discovery of a novel magnetic compound in which two magnetic dysprosium metal ions are bridged by two aromatic organic radicals forming a pancake bond. The results of this study can be utilized to improve the magnetic properties of similar compounds. The theoretical investigation of the study was carried out by the Academy Research Fellow Jani O....

A Princeton team has developed a class of light-switchable, highly adaptable molecular tools with new capabilities to control cellular activities. The antibody-like proteins, called OptoBinders, allow researchers to rapidly control processes inside and outside of cells by directing their localization, with potential applications including protein purification, the improved production of biofuels,...

Natural mixing of lake waters may resuspend contaminants deposited in a catastrophic mine spill six years ago, according to a new paper led by a University of Alberta scientist.

Antibiotic resistance is an increasing health problem, but new research suggests it is not only caused by the overuse of antibiotics. It's also caused by pollution.

Muja has lived through multiple bombing campaigns and several countries—all while never leaving a tiny pool in Belgrade's zoo for 83 years, making him the world's oldest captive alligator.

A new study, released today in Science, points to a way to repair social ties and promote coexistence after war. The study found that in post-ISIS Iraq, mixing Christians and Muslims on soccer teams made Christian players more tolerant toward Muslims in their league, though the sentiments did not extend to Muslims in the broader community. The findings suggest that meaningful social contact can...

A new federal rule that determines how the Clean Water Act is implemented leaves millions of miles of streams and acres of wetlands unprotected based on selective interpretation of case law and a distortion of scientific evidence, researchers say in a new publication.

Social inequalities, specifically racism and classism, are impacting the biodiversity, evolutionary shifts and ecological health of plants and animals in our cities.

More than half of the world's aboveground carbon is stored in tropical forests, the degradation of which poses a direct threat to global climate regulation. Deforestation removes aboveground carbon in the form of trees, reducing the size of global carbon stocks in the process. Once forests are degraded, they are often perceived to have little ecological value, despite evidence of their ability to...

Mitochondria are small organelles that provide the energy critical for each cell in our body, in particular, in the energy-demanding brain. In this week's edition of Science, a Belgian team of researchers led by Pierre Vanderhaeghen (VIB-KU Leuven, ULB) reports that mitochondria also regulate a key event during brain development: how neural stem cells become nerve cells. Mitochondria influence...
