Korean team claims to have created the first room-temperature, ambient-pressure superconductor

A team of physicists affiliated with several institutions in South Korea is claiming to have created the elusive room-temperature/ambient-pressure superconducting material. Their work has not yet been peer reviewed. They have posted two papers on the arXiv preprint server.

Physicists achieve breakthrough in Monte Carlo computer simulations

Researchers at Leipzig University have developed a highly efficient method to investigate systems with long-range interactions that were previously puzzling to experts. These systems can be gases or even solid materials such as magnets whose atoms interact not only with their neighbors but also far beyond.

New insights into the origin of the Indo-European languages

An international team of linguists and geneticists led by researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig has achieved a significant breakthrough in our understanding of the origins of Indo-European, a family of languages spoken by nearly half of the world's population. The work is published in the journal Science.

Better energy harvesting with 'law-breaking' device

If you take an object and set it out in the sun, it will begin to warm up. This is because it is absorbing energy from the sun's rays and converting that energy to heat. If you leave that object outside, it will continue getting warmer, but only to a point. A sunbather lying on a beach won't catch fire, after all.

New proof that Earth's plate tectonics recently underwent a fundamental change

Earth is truly unique among our solar system's planets. It has vast water oceans and abundant life. But Earth is also unique because it is the only planet with plate tectonics, which shaped its geology, climate and possibly influenced the evolution of life.

Team creates simple superconducting device that could dramatically cut energy use in computing

MIT scientists and colleagues have created a simple superconducting device that could transfer current through electronic devices much more efficiently than is possible today. As a result, the new diode, a kind of switch, could dramatically cut the amount of energy used in high-power computing systems, a major problem that is estimated to become much worse.

Researchers build a DNA structure and coat it with glass, creating a very low density, very strong material

Materials that are both strong and lightweight could improve everything from cars to body armor. But usually, the two qualities are mutually exclusive. Now, University of Connecticut researchers and colleagues have developed an extraordinarily strong, lightweight material using two unlikely building blocks: DNA and glass.

Researchers find evidence of a 2,000-year-old curry, the oldest ever found in Southeast Asia

It's hard to imagine a world without spice today. Fast global trade has allowed the import and export of all manner of delicious ingredients that help bring Indian, Chinese, Vietnamese, Malaysian, Sri Lankan (and so many more) cuisines to our dinner tables.

Scientists discover new isopod species in the Florida Keys

An international team of scientists from the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science and the Water Research Group from the Unit for Environmental Sciences and Management at the North-West University in South Africa have discovered a new species of marine cryptofauna in the Florida Keys.

Study shows glyphosate impairs learning in bumblebees

What impacts do agrochemicals have on the ongoing global insect decline? Biologists at the University of Konstanz have found out that aversive learning is impaired in bumblebees exposed to glyphosate. Their study is published in the journal Science of the Total Environment.
