Zipping through space at close to the speed of light, Solar Energetic Particles, or SEPs, are one of the main challenges for the future of human spaceflight. Clouds of these tiny solar projectiles can make it to Earth—a 93 million mile journey—in under an hour. They can fry sensitive spacecraft electronics and pose serious risks to human astronauts. But their onset is extraordinarily hard to...

As Richard Feynman famously put it, "the double slit experiment is absolutely impossible to explain in any classical way and has in it the heart of quantum mechanics. In reality, it contains the only mystery."

Gene editing with CRISPR enzymes inside living cells could become more effective and accurate after researchers at The University of Texas at Austin unveiled how inner workings can help or hinder the process.

A study conducted by researchers at the University of São Paulo in Brazil shows that competition for nutrients and lack of cooperation among bacteria of the species Escherichia coli in the same population and in situations of food scarcity prevent mutants that are better adapted to the environment from flourishing, except those that organize in small groups. The phenomenon masks the emergence of...

An international team led by Artem R. Oganov, a Professor at Skoltech and MISIS, and Dr. Ivan Troyan from the Institute of Crystallography of RAS performed theoretical and experimental research on a new high-temperature superconductor, yttrium hydride (YH6). Their findings were published in the journal Advanced Materials.

An international research team led by NUST MISIS has developed a new iron-cobalt-nickel nanocomposite with tunable magnetic properties. The nanocomposite could be used to protect money and securities from counterfeiting. The study was published in Nanomaterials.

Researchers hope to use an agricultural pest's genetic code against it to prevent billions of dollars in annual losses in the United States.

Bacteria employ many different strategies to regulate gene expression in response to fluctuating, often stressful, conditions in their environments. One type of regulation involves non-coding RNA molecules called small RNAs (sRNAs), which are found in all domains of life. A new study led by researchers at the University of Illinois describes, for the first time, the impacts of sRNA interactions in...

Throughout history, leather has been a popular material for clothes and many other goods. However, the tanning process and use of livestock mean that it has a large environmental footprint, leading consumers and manufacturers alike to seek out alternatives. An article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, details how sustainable materials...

Since its introduction, the emerald ash borer (EAB) has become the most devastating invasive forest insect in the United States, killing hundreds of millions of ash trees at a cost of hundreds of millions of dollars.

Effective, specific, with a reversible and non-harmful action: the identikit of the perfect biomaterial seems to correspond to graphene flakes, the subject of a new study carried out by SISSA—International School for Advanced Studies of Trieste, Catalan Institute of Nanoscience and Nanotechnology (ICN2) of Barcelona, and the National Graphene Institute of the University of Manchester, as part of...

New research conducted at the UNESCO World Heritage listed 'Plain of Jars' in Laos has established the stone jars were likely placed in their final resting position from as early as 1240 to 660 BCE.

Genetic analysis provides clarity and also prompts further questions around an ancient massacre in Potočani, Croatia, in a study published March 10, 2021 in the open-access journal PLOS ONE by Mario Novak from the Institute for Anthropological Research, Croatia, Ron Pinhasi from the University of Vienna, Austria, David Reich from Harvard Medical School and Harvard University, U.S., and...

Scythian people of ancient Ukraine led more complex lives than commonly assumed, according to a study published March 10, 2021 in the open-access journal PLOS ONE by Alicia R. Ventresca Miller of the University of Michigan and colleagues.

Unusual seismic activity in a volcanic zone near Iceland's capital Reykjavik that has been dormant for almost 800 years has left experts stumped and searching for clues as to whether an eruption is imminent.

Climate envoy John Kerry confirmed Wednesday the United States would lay out new financing commitments for the Paris Agreement to cut greenhouse gas emissions ahead of an April 22 summit, the pact's fifth anniversary.

As plastic debris weathers in aquatic environments, it can shed tiny nanoplastics. Although scientists have a good understanding of how these particles form, they still don't have a good grasp of where all the fragments end up. Now, researchers reporting in ACS' Environmental Science & Technology have shown experimentally that most nanoplastics in estuarine waters can clump, forming larger...

In the dry air and soil of Texas' Southern High Plains, improving soil health can be tough. We usually think of healthy soil as moist and loose with lots of organic matter. But this can be hard to achieve in this arid area of Texas.

What goes up, nearly always comes back down. When it comes to the objects we send to space, atmospheric reentries are actually a fundamental tool in minimizing the creation of space debris and ensuring a sustainable future in space.

Severe river floods are escalating in temperate climates and putting at risk populations, livelihoods and property, according to evidence published today in Geophysical Research Letters by an Oxford-led international team.

There's a surprising amount of information stored in the hardened plaque, or calculus, between teeth. And if that calculus belongs to the remains of a person who lived in ancient times, the information could reveal new insights about the past. But the tiny samples can be difficult to work with. Now, in ACS' Journal of Proteome Research, scientists apply a new method to this analysis, finding more...

Scientists at Tokyo Institute of Technology (Tokyo Tech) have uncovered mechanisms underlying the activation of the MRN complex—the cell's DNA scissors. Using purified yeast proteins, they demonstrated that phosphorylation of Ctp1, a homolog of a tumor-suppressor protein, plays a key role in activating MRN complex's DNA clipping activity. Intriguingly, a short segment of yeast Ctp1 or its human...

Nearly 100 percent of the red snapper sampled in the Gulf of Mexico over a six-year period by University of South Florida (USF) marine scientists showed evidence of liver damage, according to a study reported in Aquatic Toxicology.

Recent studies estimate that we use an astounding 129 billion face masks globally every month—that is 3 million a minute. Most of them are disposable face masks made from plastic microfibers.
