In a discovery published in the journal Nature, an international team of researchers has described a novel molecular device with exceptional computing prowess.

A team, including Lancaster University academics, have taken the first crucial steps to stamp out the worldwide atrocities of witchcraft, including ritual killings, with the successful acceptance of a United Nations Resolution.

California grape growers in coastal areas can use less water during times of drought and cut irrigation levels without affecting crop yields or quality, according to a new study out of the University of California, Davis.

Decades of research have been dedicated to understanding humpback whale songs. Why do they sing? What and where is the intended audience of these songs? To help uncover the answers, many scientists have framed whale songs as something similar to bird songs: vocalizations designed for attracting potential mates, or warnings to competitors.

Lawrence Livermore National Laboratory (LLNL) scientists are working on a new diagnostic capability that will provide, for the first time, the ability to make X-ray radiographic movies.

Nearly 20 years after the United States' invasion of Afghanistan, the cost of its global war on terror stands at $8 trillion and 900,000 deaths, according to a new report from the Costs of War project at Brown University.

What began as a curious survey of an insect in Florida revealed a much larger network of movement across the Caribbean basin. Haplaxius crudus, commonly known as the American palm cixiid, transmits phytoplasmas (bacteria that cause plant diseases) in palm. The American palm cixiid is known to transmit lethal yellowing disease and lethal bronzing disease, both of which are lethal to a variety of palm species, especially coconut and date palms.

Rice physicists have confirmed the topological origins of magnons, magnetic features they discovered three years ago in a 2D material that could prove useful for encoding information in the spins of electrons.

University of Central Florida researchers have developed a nanoparticle-based disinfectant that can continuously kill viruses on a surface for up to seven days—a discovery that could be a powerful weapon against COVID-19 and other emerging pathogenic viruses.

When the humidity in the atmosphere is relatively high, the particles naturally present, also known as aerosol droplets, grow to play a significant role in the chemistry and climate of Earth. These particles are produced from either clean or polluted air, after emissions of gases that nucleate and condense while in the atmosphere. Many times this process is affected by the presence of organic (2-oxocarboxylic) acids that have been characterized to be present over polluted cities.

Climate change could increase the release of greenhouse gases from insect-driven forest decay, a new study has found.

An Imperial-led team of international researchers has used a special X-ray probe to gain new insights into how electrons behave at the quantum level.

When NASA's Mars 2020 Perseverance rover touched down on the Red Planet, the agency's Deep Space Network (DSN) was there, enabling the mission to send and receive the data that helped make the event possible. When OSIRIS-REx took samples of asteroid Bennu this past year, the DSN played a crucial role, not just in sending the command sequence to the probe, but also in transmitting its stunning photos back to Earth.

In Greece, drivers cannot legally purchase custom vanity plates. However, a new study confirms an open secret: that the country has an illegal market for acquiring license plates with distinctive number patterns, perhaps as a form of "conspicuous corruption." Panos Louridas and Diomidis Spinellis of the Athens University of Economics and Business, Greece, report their findings in the open-access journal PLOS ONE on September 1, 2021.

In the face of grave concerns about misinformation, social media networks and news organizations often employ fact-checkers to sort the real from the false. But fact-checkers can only assess a small portion of the stories floating around online.

Sites favored by illegal cannabis farmers on the West Coast of the United States overlap with the habitat ranges of three threatened predators, potentially exposing them to toxic pesticides, according to a study by Greta Wengert at the Integral Ecology Research Center in California and colleagues, publishing September 1 in the open-access journal PLOS ONE.

Dutch scientists were on Wednesday probing the mysterious deaths of dozens of harbour porpoises whose carcasses have been washing up on the country's northern beaches since last week.

In the early solar system, terrestrial planets like Mercury, Venus, Earth and Mars are thought to have formed from planetesimals, small early planets. These early planets grew over time, through collisions and mergers, to make them the size they are today.

The familiar star at the center of our solar system has had billions of years to mature and ultimately provide life-giving energy to us here on Earth. But a very long time ago, our sun was just a growing baby star. What did the sun look like when it was so young? That's long been a mystery that, if solved, could teach us about the formation of our solar system—so-named because sol is the Latin word for sun—and other stellar systems made up of planets and cosmic objects orbiting stars.

In a new paper in the Georgetown Journal of International Affairs, seven researchers hailing from five countries have called for greater attention to the destructive potential and recent history of disasters seen in the world's mountain ranges, including places like the Himalaya and Andes.

Living trees absorb a considerable amount of carbon dioxide from the atmosphere and therefore play an important role in the protection of our climate. Little is known about the role of dead trees in the global carbon cycle, though. The decomposition of wood and the recycling of the nutrients it contains are among the most important processes to take place in forests.

Viruses kill millions around the world each year. "In addition to the novel coronavirus, leading viral killers include hepatitis, HIV, HPV," said Lela Vukovic, Assistant Professor of Chemistry, University of Texas at El Paso.

A new study published today in the journal Environmental Science & Technology finds that exposing certain nanomaterials to light can influence their environmental transformation, fate and, ultimately, their toxicity. The discovery provides new insights into the behavior of engineered nanomaterials and how they can be better designed for numerous commercial applications without impacting the environment or human health.

Over the past few years, scientists have demonstrated how cage-like, porous structures made of silicon and oxygen and measuring only billionths of a meter in size can trap noble gasses like argon, krypton, and xenon. However, for these silica nanocages to be practically useful—for example, to improve the efficiency of nuclear energy production—they need to be scaled up from their lab versions. The scientists have now taken a step forward in bringing this technology out of the lab and into the real world. Читать дальше...

If you have a pet—specifically a dog—then you have probably heard about kennel cough, an infection caused by bacteria or viruses that causes respiratory irritation and a deep, painful-sounding cough. In recent months, kennel cough cases have spiked nationally, forcing kennels to close for sanitation and veterinary visits to surge.
