There's no sign that methane emissions are declining globally.
NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution of these elements throughout the young solar system. The
An international team of scientists has discovered that plants are not responding to global warming in the way researchers long assumed. Scientists have expected that ecosystems would keep pace with warming by rising the temperature at which photosynthesis works best.
Globally, agriculture faces mounting pressures. These are driven by climate change, land degradation, labor shortages, supply chain disruptions and the demand for food from a growing population.
Scientists at the SETI Institute recently searched for technological signals from 3I/ATLAS, the third interstellar object observed in our solar system. Using the Allen Telescope Array (ATA) at the Hat Creek Radio Observatory in Northern California, the team scanned a wide range
El Niño is a recurring climate event with impacts across the globe. It has three phases: one cold (known as La Niña), one neutral, and one warm (El Niño).
The arrival of winter marks not only a change in weather, temperature, and day length, but also a change in our activity and behavior. The social outdoor events and trips to the beach over summer soon become a distant memory, and we ready ourselves for more solitary evenings
Off the southern coast of Japan, the Philippine Sea Plate lies underneath the Japanese mainland. The locked tectonic plates threaten to unleash a catastrophic megathrust earthquake, likely within the next few decades. Given the potential devastation a large quake could evoke,
A defendant stands in the dock. An expert describes them as a "psychopath." In an instant, one word threatens to eclipse their history, circumstances and the crime itself.
Diminutive warty birch caterpillars (Falcaria bilineata), less than 1.5mm long, ardently defend their leaf tip homes from invading caterpillars by scraping and pounding the leaf to warn off potential invaders. But how might the day-old caterpillars defend themselves when
Human-made objects are just too tempting The post Watch How “Trashy” City Bowerbirds Attract Their Mates appeared first on Nautilus .
Though decaf fans might disagree, caffeine is a critical component of a cup of joe. This compound is incredibly bitter on its own, but regular coffee itself is not. A team reporting in the Journal of Agricultural and Food Chemistry has investigated why and explains that the
For more than 30 years, manufacturers of ski and snowboard waxes have used PFAS—per- and polyfluoroalkyl substances—to make skis and snowboards glide faster over snow. These synthetic chemicals were highly effective and common in competitive racing just about everywhere.
Potent drugs like chemotherapy can be life-saving, but often with life-threatening side effects. Notably, they can be indiscriminate, killing both cancer cells and healthy cells in one swoop. Increasing a drug's on-target efficiency can reduce side effects and enable healthier
When a person coughs or sneezes, they expel a cloud of microscopic particles capable of carrying viruses and bacteria that act as vectors for respiratory diseases such as flu, COVID-19 or tuberculosis. Understanding how these aerosols disperse in the air is crucial for
Summer brings with it the sight of surfers moving seamlessly across wave crests, with ocean waters carrying them along coastlines. A team of scientists has now created a similar phenomenon—with small objects rather than surfers—that can be controlled by humans rather than by
UCF College of Medicine Assistant Professor Renee Fleeman continues to refine a powerful therapy for drug-resistant bacteria that pierces the gooey coating that anchors and protects such germs from the drugs we take to kill them. Her research has found that an antimicrobial
Nanodiamonds are tiny diamond particles only a few nanometers in size. Because they are chemically highly stable and can host so-called color centers, optically active defects in the crystal lattice, they are considered promising materials for quantum technologies, sensing and
Researchers at IMDEA Materials Institute have developed a new hybrid methodology that combines quantum mechanics and thermodynamic calculations to predict the phase diagram of nickel-cobalt alloys.
The weather on Earth can get pretty messy sometimes. But in space, it can be wild, and the effects can be far-reaching. Solar flares, giant explosions on the sun, can send out streams of energy that block radio communications and fry satellite electronics. Geomagnetic storms,
We’re not in Kansas anymore, but you knew that The post Stupid in the Land of Oz appeared first on Nautilus .
In its native habitat, switchgrass flowered earlier when growing farther north. In experiments with diverse genetic samples, it flowered earlier in the south.
Scientists from the Space Telescope Science Institute (STScI) in Baltimore, Maryland, sought to study one stellar subject and ended up finding something even more exciting. The team's results published today in Astronomy & Astrophysics.
Close to 100 scientists from all over Europe, the United States, and Japan are gathering this week at the Institute for Solar Physics (KIS) in Freiburg to present and discuss the first scientific results from the successful third flight of the balloon-borne solar observatory
Humans can communicate various instructions to dogs without using actual words—simply by modulating the tone of their voice, a new study from ELTE University's Department of Ethology shows. By repeating the nonsense syllable 'bü' in different intonations, humans successfully
Quantum computing, once only a theoretical possibility, promises to deliver faster, more energy-efficient computers—but only if scientists can build and scale the hardware needed to run the machines. New research from Virginia Commonwealth University brings scientists one small
The Hadley circulation, a key atmospheric conveyor belt transporting heat and moisture from the tropics to the subtropics, directly influences subtropical aridity, the positions of tropical rainfall belts, and extreme weather risks. However, climate models have long shown
Many rivers flow into the Arctic Ocean north of the Arctic Circle—including the Lena in Siberia and the Mackenzie River in Canada. The deltas of these large and small rivers store large amounts of carbon, which is bound there in frozen soils and sediments. Climate change,
Computational chemists at the University of Amsterdam's Van 't Hoff Institute for Molecular Sciences have developed a comprehensive software suite to create accurate models of DNA in biomolecular assemblies. Called MDNA, the user-friendly molecular modeling toolkit helps
In 2010, the New York City-based restaurant Serendipity 3 revealed its $69 hot dog, winning the Guinness World Record for the world's most expensive hot dog. Served on a toasted pretzel roll with truffle butter and covered in foie gras, the award-winning hot dog made the
An international team of researchers including our Department of Geography has discovered a vast geological structure hidden beneath the East Antarctic Ice Sheet. The findings are published in the journal Nature Geoscience.
Young guppies who were able to see and interact with live fish developed larger brains than guppies who only saw other fish on a screen. This is shown in a new study from Stockholm University, published in Biology Letters. The findings suggest that live social interaction in
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a new method to recycle mixed plastic packaging without using harmful chemical solvents—an approach that could make one of the world's most difficult waste streams significantly easier to
Why do certain surfaces behave very differently from what theoretical calculations suggest? Scientists long assumed that the aluminum oxide surface should be highly reactive and capable of splitting water molecules. In experiments, however, this behavior is barely observed.
A new study in Nature Communications finds a critical climate tipping point in Tibetan permafrost ecosystems. Warming of 2–4 degrees Celsius triggers a self-reinforcing cycle of carbon release that could significantly accelerate climate change, according to the work.
