This episode of Reactions dives into something truly out-of-this-world: amorphous ice.

There could be billions of shallow lakes and ponds on Earth, though lack of mapping systems makes it hard to know just how many exist. Together, they emit significant amounts of greenhouse gases into the atmosphere, but emissions from these systems vary considerably and are not well understood.

Canada is facing a dire wildfire situation through the coming months, officials warned on Monday after vast swaths of forests and grasslands from its Pacific to Atlantic coasts have been scorched.

The digital age has been a tremendous boon to the fields of both statistics and astronomy. However, according to Dr. Max Bonamente, a professor of physics and astronomy at The University of Alabama in Huntsville (UAH), most astronomers are not sufficiently trained to realize the substantial benefits to be gained by putting these disciplines together. He and his colleagues are working to change all...

Studying radioactive materials is very difficult due to the potential health risks they pose to scientists. Expense is also a major barrier, with some radioisotopes costing more than $10,000 per microgram (or $10 billion per gram). Some radioisotopes cannot be produced in sufficient quantities, making them difficult to study in detail with current techniques. Scientists have recently developed a...

Billions of tons of snow piled atop the Sierra Nevada Mountains can cause parts of the Central Valley, just west of the range, to sink—muddling groundwater assessments that take sinking as a sign of depleted aquifers. A recent Stanford University study is now offering a way to account for this heavy mountain snowpack and more accurately gauge groundwater levels.

A new "digital decision support tool" enabling the transition towards more diversified and sustainable agricultural systems has been developed by an international team of researchers from Germany, France, and Czech Republic.

A fossil from a rare dinosaur that roamed South America 110 million years ago has been returned to Brazil from Germany, ending a diplomatic spat triggered by charges that researchers stole it.

Risk assessment instruments (RAIs) are widely used to inform high-stakes decision-making in the criminal justice system and other areas, such as health care and child welfare. These tools typically assume a relation between predictors and outcomes that does not vary with time. But because societies change, this assumption may not hold in all settings, generating what a new study calls cohort...

California's complex system of water rights took shape starting in the mid-1800s, when settlers saw the state's water as abundant and free for the taking—a time when a Gold Rush prospector could stake claim to river flows simply by nailing a notice to a tree.

Coming out to your parents can be a difficult and sensitive process for a person at any age. But for Hispanic teens, sharing that information can become even more challenging.

Interfacial reactions happen at the boundary where materials in different phases, for example a solid and a liquid, meet each other. These reactions drive all elemental cycling on Earth and play pivotal roles in human activities such as agriculture, water purification, energy production and storage, environmental contaminant remediation, and nuclear waste repository management.

Donning Indiana Jones hats and astronaut-like suits, Lee Berger is something of a paleontology action hero.

Following Russia's invasion of Ukraine in 2022, Western governments implemented a suite of sanctions on Russian businesses, escalating the sanctions they implemented following Russia's annexation of Crimea in 2014. The goal in both cases was to inflict enough pain on Russian elites that they would pressure Vladimir Putin to reverse course and end the conflict.

In a study published in the journal National Science Review and led by Dr. Zhongbao Jian (State Key Laboratory of Polymer Physics and Chemistry, Changchun Institute of Applied Chemistry, CAS), E/CO/PM terpolymerizations were carried out with seven palladium catalysts, which were strictly non-alternating (>99%) with Pd4.

In early 2014, a great anomaly descended upon the seas: A patch of warm water that manifested in the Gulf of Alaska. Scientists called it "The Blob."

Especially after the last few COVID-affected years, nobody doubts that emerging infectious diseases can threaten the whole world. But humans are not the only ones at risk. With intensive global trade, many tree parasites are accidently introduced to Europe in packaging or directly on goods. Traveling in wood, on plants or in the soil of their pots, they can remain undetected for a long time.

Understanding the behavior of nuclear matter—including the quarks and gluons that make up the protons and neutrons of atomic nuclei—is extremely complicated. This is particularly true in our world, which is three dimensional. Mathematical techniques from condensed matter physics that consider interactions in just one spatial dimension (plus time) greatly simplify the challenge.

Researchers at the University of Liège, Eric Parmentier and Marc Thiry have just made the unexpected discovery of a novel organization of muscle fibers in Parophidion vassali, a fish that lives in the Mediterranean Sea and, like many fish, uses specialized muscles to produce sounds. This is an important discovery that could well change our understanding of muscle contraction.

Striking differences in the content shared by people who live in wealthier versus poorer neighborhoods has led researchers to believe that our general online posting activity, beyond Nextdoor, can reveal our socioeconomic status, making user profiling possible.

Researchers from the Griffith Asia Institute (GAI) have proven that lower application rates of fertilizers do not affect the yield or quality of two mango varieties in Southern Vietnam.

Cancer surgeons may soon have a more complete view of tumors during surgery, thanks to new imaging agents that can illuminate multiple biomarkers at once, University of Illinois Urbana-Champaign researchers report. The fluorescent nanoparticles, wrapped in the membranes of red blood cells, target tumors better than current clinically approved dyes and can emit two distinct signals in response to...

Preserving endangered and typical habitats in Europe with their biodiversity is the goal of Natura 2000, a network of nature reserves established by the EU. By 2030, EU member states want to significantly expand this network.
