Experts and cave divers in Mexico's Yucatan peninsula have found ocher mines that are some of the oldest on the continent, which could explain why ancient skeletons were found in the narrow, twisting labyrinths of now-submerged sinkhole caves.

Figuring out how much energy permeates the center of the Milky Way—a discovery reported in the July 3 edition of the journal Science Advances—could yield new clues to the fundamental source of our galaxy's power, said L. Matthew Haffner of Embry-Riddle Aeronautical University.

Utah State University biologist Edmund 'Butch' Brodie, Jr. and colleagues from São Paulo's Butantan Institute report the first known evidence of oral venom glands in amphibians. Their research, supported by the Brazilian National Council for Scientific and Technological Development, appears in the July 3, 2020, issue of iScience.

An international team of scientists from Austria, Germany, and Ukraine has found a new superconducting system in which magnetic flux quanta can move at velocities of 10 to 15 km/s. This opens access to investigations of the rich physics of non-equilibrium collective systems and renders a direct-write Nb-C superconductor as a candidate material for single-photon detectors. The results are published...

A team of researchers at the University of California has found that the histone H3-H4 tetramer is a copper reductase enzyme. In their paper published in the journal Science, the group describes two experiments they carried out that showed that histones are involved in reducing copper inside of cells. Johannes Rudolph and Karolin Luger with the University of Colorado at Boulder have published a...

A research group led by Prof. Cao Hongtao at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS), has developed a novel direct growth method of vertically orientated nanocavity arrays to generate plasmonic structural colors, which feature wide gamut, improved color saturation, excellent stability in ambient condition and mass-production...

Even today, nobody can reliably predict when and where an earthquake will occur. However, eyewitnesses have repeatedly reported that animals behave unusually before an earthquake. In an international cooperation project, researchers from the Max Planck Institute of Animal Behavior in Konstanz/Radolfzell and the Cluster of Excellence Center for the Advanced Study of Collective Behavior at the...

Last year, Google produced a 53-qubit quantum computer that could perform a specific calculation significantly faster than the world's fastest supercomputer. Like most of today's largest quantum computers, this system boasts tens of qubits—the quantum counterparts to bits, which encode information in conventional computers.

The massive star that exploded to form the supernova known as Cassiopeia A most likely had a companion star that has yet to be spotted, a spectroscopic analysis by RIKEN astrophysicists suggests. This will provide fresh impetus to efforts to locate the companion.

When major sports leagues and events shut down or were postponed earlier this year, the move was a powerful message for many that the COVID-19 pandemic needed to be taken seriously—even these bastions of social life around the world were taking measures to prevent the spread of the coronavirus.

Let's turn back time. Before extinction knocked dinosaurs off their pillar, before the "Great Dying" extinction wiped out 95% of all organisms—we had the Paleozoic Era.

Beavers and wolverines in northern Alberta are using industry-created borrow pits as homes and feeding grounds, according to a new study by University of Alberta ecologists.

Hauffiopteryx altera (Latin for different from) has been identified as a new species of Ichthyosaurs by researchers from McGill University and the State Museum of Natural History Stuttgart in Germany.

It was a dark time for animals. Poaching was rampant. Wild birds and mammals were being slaughtered by the thousands. An out-of-control wildlife trade was making once-common animals hard to find and pushing rare species into extinction.

Coronavirus has had an unprecedented impact on pubs in Britain. The British Beer and Pub Association estimates that the industry lost over £100m each month of lockdown.

Scientists have made a pivotal breakthrough in the important, emerging field of spintronics—which could lead to a new high speed energy efficient data technology.

The first comprehensive worldwide assessment of heatwaves down to regional levels has revealed that in nearly every part of the world heatwaves have been increasing in frequency and duration since the 1950s.

Toxic chemicals are being used by food sellers across sub-Saharan Africa to improve the look of meat and fish, scientists and food inspectors say, putting the health of millions at risk.

The term "heatwave" is no stranger to Australians. Defined as when conditions are excessively hot for at least three days in a row, these extreme temperature events have always punctuated our climate.

A new group of trapdoor spiders that builds burrows hidden by camouflaged doors has been discovered in eastern Australia. One of the almost 20 new species found in this group occurs in the suburbs of Brisbane.

A new report from Imperial and Sainsbury's outlines how well-managed fridges can keep food cooler, be greener, and cut costs.

Easily produced, nature-like nanostructures of cobalt phosphide are highly effective catalysts for the electrolysis of water, according to research performed by chemist Ning Yan and his team at the University of Amsterdam's Van 't Hoff Institute for Molecular Sciences together with co-workers from the School of Physics and Technology at Wuhan University, China. In a paper featured on the front...

The coffee-stain effect is a well-known effect in physics and daily life in which a dark-colored edge remains when a fluid containing particles evaporates. This is caused by an "avalanche" of particles moving to the outer edge, University of Twente scientists showed in a past study. In inkjet and 3-D printing, this is an undesired effect. Now, researchers have demonstrated that the effect can be...

A new discussion paper published in Policy Sciences by two Leiden researchers claims that governments are working with one hand tied when it comes to data on vulnerable groups. At the core of this paper is the idea that even though the volume of data has increased in recent years, the quality of the data in combination with potential known or unknown data gaps limits government's ability to create...
