Computational detective work by physicists has confirmed cerium zirconium pyrochlore is a 3D quantum spin liquid, a solid material in which quantum entanglement and the geometric arrangement of atoms cause electrons to fluctuate between quantum magnetic states no matter how cold they become.

The aviation industry faces multiple pressures from higher fuel costs and increased scrutiny over the environmental and quality-of-life impacts from its aircraft. Researchers are looking for new methods of keeping expenses down while improving overall efficiency, and the relatively new market of unmanned aerial vehicles (UAVs) -- or drones -- is no exception.

A new study has revealed the strongest evidence to date that all bison in North America carry multiple small, but clearly identifiable, regions of DNA that originated from domestic cattle.

Scientists suggest telltale signs of concussions might be found in the gut. By taking blood, stool and saliva samples from 33 football players, the researchers were able to examine the diagnostic potential of the gut's microbiome. They say their findings demonstrate that a simple, objective diagnostic test could be developed to track the impact of concussions and signal when it's safe to return to...

The first detailed academic study of East African maritime traditions shows changes in boatbuilding techniques but the continuing use of wooden vessels by fishers.

Thanks to their easily fossilized exoskeleton, trilobites largely dominate the fossil record of early complex animal life. However, trilobite appendages and the anatomy of the underside of their body are typically not well preserved, which makes it difficult to infer their mating and reproductive behaviors.

Research that examines how the body adapts to new movements is shedding new light on how the nervous system learns, and could help to inform a wide range of applications, from customized rehabilitation and athletic training to wearable systems for healthcare.

In our sun's neighborhood of the Milky Way Galaxy is a relatively bright star, and in it, astronomers have been able to identify the widest range of elements in a star beyond our solar system yet.

It is well documented that lying during interviews takes up more cognitive energy than telling the truth.  A new study found that investigators who used this finding to their advantage by asking a suspect to carry out an additional, secondary, task while being questioned were more likely to expose lie tellers. The extra brain power needed to concentrate on a secondary task (other than lying) was...

Humans are undoubtedly altering the natural environment. But how wild animals respond to these changes is complex and unclear. Scientists have now discovered significant differences in how the brain works in two distinct personality types: those who act fearless and those who seem afraid of new things. Being fearless can help wildlife, specifically birds, find new food sources, explore new nesting...

Researchers have discovered that before cells start to divide, they toss waste products. Using a new method they developed for measuring the dry mass of cells, the researchers found cells suddenly lose mass as they enter cell division.

Perovskite materials may hold the potential to play an important role in a process to produce hydrogen in a renewable manner, according to a recent analysis. Hydrogen has emerged as an important carrier to store energy generated by renewable resources, as a substitute for fossil fuels used for transportation, in the production of ammonia, and for other industrial applications.

In a recent study,botanists investigated the effects of increasing the amount of carbon dioxide channels in plant membranes, but could not detect any impact on photosynthesis in model tobacco plants.

Settling a key dispute in the wireless communications field, researchers found that transmission performance is consistent across different bands of the millimeter-wave (mmWave) spectrum targeted for high-speed, data-rich 5G systems.

Scientists describe their work on an at-home study of rheology, which is used to study the way non-Newtonian liquids or semisolid substances flow. The projects assigned to students had two parts: gathering qualitative visual evidence of rheological properties and taking quantitative measurements. The students checked for four behaviors -- shear thinning viscosity, viscoelasticity, shear normal...

Researchers present clinicians with information about the risk factors for atherosclerotic plaque formation from a mechanical point of view. The scientists are exploring whether it is possible to screen and intervene early for people at risk for atherosclerotic disease from the perspective of hemodynamics, using color Doppler ultrasound, coronary computed tomography angiography, and other...

Healthy adults who eat a diverse diet with at least 8-10 grams of soluble fiber a day have fewer antibiotic-resistant microbes in their guts, according to a new study. The results lead directly to the idea that modifying the diet has the potential to be a new weapon in the fight against antimicrobial resistance. And this does not require eating some exotic diet, but eating a diverse diet, adequate...

Researchers found that less than half of Americans who received treatment for opioid use disorder over a five-year period were offered a potentially lifesaving medication. The numbers were even lower for those with what's known as polysubstance use disorder -- when opioid users also misuse other substances.

Researchers show that cancer cells in an acidic environment undergo lipid synthesis and accumulation. The team identified the key signaling molecules responsible for these changes and discovered that these alterations are associated with poor outcomes and disease progression among breast cancer patients.

Tumors can force neighboring cells into supporting cancer growth by releasing lactate into their local environment, according to researchers. The findings pave the way for future drug treatments that thwart that defense mechanism to help cancer patients.

Scientists reported on an experimental gene-therapy-like technique to restore the normal activity of the TCCF4 gene deficient in individuals with Pitt-Hopkins syndrome.

Engineers have developed p-channel transistors through halide anion engineering. The new technology realizes a threshold voltage of 0 V and is hysteresis-free and high performing.

A national study that enrolled a highly diverse group of pregnant women over 12 years found rising exposure to chemicals from plastics and pesticides that may be harmful to development.

It's always rewarding when what started out as largely an academic endeavor turns out to impact a lot of people -- in this case women. Women suffering from endometriosis, polycystic ovary syndrome (PCOS) and preeclampsia may be protected from future heart disease if they carry a specific common genetic variant on the surface of cells (insulin-like growth factor-1 receptor, or IGF1R). The research...
