David Bennett, 57, is doing well three days after the experimental surgery, doctors say.
Deeper analysis of fossils from one of Eastern Europe's most significant paleontological sites has led to the discovery of a new species of pangolin, previously thought to have existed in Europe during the early Pleistocene but not confirmed until now.
Florida State University researchers have new insight into the complicated puzzle of environmental conditions that characterized the Late Ordovician Mass Extinction (LOME), which killed about 85% of the species in the ocean.
In a medical first, doctors transplanted a pig heart into a patient in a last-ditch effort to save his life and a Maryland hospital said Monday that he’s doing well three days after the highly experimental surgery. While it’s too soon to know if the operation really will work, it marks a step in the decades-long quest to one day use animal organs for life-saving transplants. Doctors...
It's widely understood that animals such as salmon, butterflies and birds have an innate magnetic sense, allowing them to use the Earth's magnetic field for navigation to places such as feeding and breeding grounds.
A study published by researchers at the University of Illinois Chicago describes a new method for analyzing pyroptosis—the process of cell death that is usually caused by infections and results in excess inflammation in the body—and shows that process, long thought to be irreversible once initiated, can in fact be halted and controlled.
The discovery of a supermassive black hole in a relatively small galaxy could help astronomers unravel the mystery surrounding how the very biggest black holes grow.

A treasure trove of some 200 Roman-era coins was discovered in northwestern Spain thanks to the apparent efforts of a hungry badger hunting for food, archaeologists have said.
The notion that some computational problems in math and computer science can be hard should come as no surprise. There is, in fact, an entire class of problems deemed impossible to solve algorithmically. Just below this class lie slightly "easier" problems that are less well-understood—and may be impossible, too.
A snowy owl apparently touring iconic buildings of the nation's capital is captivating birdwatchers who manage to get a glimpse of the rare, resplendent visitor from the Arctic.
Dig this: Catalysis appears to function because of holes.
In the particle world, sometimes two is better than one. Take, for instance, electron pairs. When two electrons are bound together, they can glide through a material without friction, giving the material special superconducting properties. Such paired electrons, or Cooper pairs, are a kind of hybrid particle—a composite of two particles that behaves as one, with properties that are greater than...
In the fields of chemistry and materials, most successful, widely used machine learning schemes introduced over the last decade aim to model molecular energies or interatomic potentials. Accordingly, the representations used to map atomic configurations into vectors of descriptors or features used as model inputs reflect fundamental properties of the interatomic potential such as invariance to...
Ordinary matter behaves very differently when subjected to extreme temperatures and pressures, such as that inside stellar and planetary cores. Conventional rules of condensed matter physics and plasma physics are not applicable in such scenarios. In particular, an extreme state known as "warm dense matter" (WDM) straddles the boundary of condensed matter physics and plasma physics.
The recovery of the fisher, a charismatic, long-tailed forest carnivore, will likely be hindered by the increasing frequency and intensity of future wildfires, new research by Oregon State University indicates.
Within three decades, the San Joaquin Valley's annual average temperature could increase by 4 degrees, worsening water quality and health hazards in the impoverished communities of California's agricultural heartland, according to a new regional climate change report.
AMOLF researchers, collaborating with researchers from the Erasmus MC, have discovered a genetic mechanism that ensures that a nerve cell retains its identity once it has differentiated. This concerns a neuron in the worm C. elegans that can detect salt. Its identity is activated by a genetic switch during the cell's development. Jeroen van Zon and his colleagues have discovered how it is possible...
Ecological communities on the Oregon coast are being subtly destabilized by the pressures of climate change despite giving an appearance of stress resistance, new research by Oregon State University shows.
Marine life hitching a ride on ocean-crossing ships poses a threat to Antarctica's pristine ecosystems, with the potential for invasive species to arrive from almost anywhere across the globe, say the authors of a new study.
Scientists have developed an innovative technique using small wearable sensors to gather data on how people -- who have suffered from a traumatic hand amputation -- use a prothesis versus a transplanted hand in everyday life. So far, the data shows people with a transplanted hand demonstrate a more balanced use of their hands than those who use a prothesis.
Researchers studying locusts have found that the presence of smell can be determined by simply adding and subtracting the presence of certain neurons.
The recovery of the fisher, a charismatic, long-tailed forest carnivore, will likely be hindered by the increasing frequency and intensity of future wildfires, new research indicates.
Results of a new study represent a step toward improving our understanding of Crohn's disease and the factors that cause its intestinal inflammation.
Consuming more than 7 grams (>1/2 tablespoon) of olive oil per day is associated with lower risk of cardiovascular disease mortality, cancer mortality, neurodegenerative disease mortality and respiratory disease mortality, according to a new study. The study found that replacing about 10 grams/day of margarine, butter, mayonnaise and dairy fat with the equivalent amount of olive oil is associated...
The fossilized remains of an ichthyosaur have been found in England's Midlands, the largest and most complete of its kind discovered in the...
You're likely familiar with the idea of the sterile mule: a hybrid animal born of a horse and a donkey that is unable to breed.
Nearly 700 people died due to natural disasters in the contiguous United States in 2021—the most since 2011, said a federal weather agency in a report released Monday.
Whether a transformer catches fire in a power grid, a species disappears from an ecosystem, or water floods a city street, many systems can absorb a certain amount of disruption. But how badly does a single failure weaken the network? And how much damage can it take before it tips into collapse?
Newly developed risk scores synthesize genetic information into an easy-to-interpret metric that could help clinicians identify young children most at risk of developing obesity. The study used a novel statistical methods to establish scoring criteria using data collected from children from birth to three years of age.
The United States staggered through a steady onslaught of deadly billion-dollar weather and climate disasters in an extra hot 2021, while the nation's greenhouse gas emissions last year jumped 6% because of surges in coal and long-haul trucking, putting America further behind its 2030 climate change cutting goal.
Trevor Franklin, a doctoral student in Cornell's Robert Frederick Smith School of Chemical and Biomolecular Engineering, was preparing a study about anti-fouling surfaces when he noticed something strange.
Almost 100 billion tons of CO2 could be pulled out of the atmosphere by the end of the century. That is, if high-income countries switch to a plant-based diet. The double carbon profit of returning farmland to its natural state would equal about 14 years' worth of agricultural emissions, researchers from Leiden University write in Nature Food.
Atomic environment fingerprints, or structural descriptors, are used to describe the chemical environment around a reference atom. Encoding information such as bond-lengths to neighboring atoms or coordination numbers, these fingerprints are used, for example, as inputs in machine learning approaches or to eliminate redundant structures in structural searches
