Campaigners say UK government protections on the environment are already being flouted.
The threat to you garden is low, but it can trigger allergies, says Kath Smyth with the Calgary Horticultural Society.
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.
Police in Port Moody, B.C., say a dog has been killed following a cougar attack in a quiet residential area early Wednesday...
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...
DNA, archaeological and skeletal evidence demonstrates an indiscriminate massacre and haphazard burial of 41 individuals from an early pastoralist community in what is now eastern Croatia 6,200 years ago.
In a recent study, aspirin use to avoid the development of cardiovascular diseases in healthy individuals was associated with a 29 percent lower likelihood of COVID-19 infection, as compared to aspirin non-users. The proportion of patients treated with aspirin was significantly lower among the COVID-19-positive individuals, as compared to the COVID-19-negative ones. And those subjects who had been...
Geoscientists used 3D-printed rocks and an advanced, large-scale computer model of past earthquakes to understand and prevent earthquakes triggered by energy exploration.
New research finds that Scythian people of ancient Ukraine led more complex lives than commonly assumed.
Computer engineers at the world's largest companies and universities are using machines to scan through tomes of written material. The goal? Teach these machines the gift of language. Do that, some even claim, and computers will be able to mimic the human brain. But this impressive compute capability comes with real costs, including perpetuating racism and causing significant environmental damage,...
A gene therapy for chronic pain could offer a safer, non-addictive alternative to opioids. Researchers have developed the new therapy, which works by temporarily repressing a gene involved in sensing pain. It increased pain tolerance in mice, lowered their sensitivity to pain and provided months of pain relief without causing numbness.
A new systematic review of 65 studies from around the world involves a total of 97,333 health care workers and finds that one in five have experienced depression, anxiety, and/or PTSD during the ongoing COVID-19 pandemic.
Scientists have identified key genes involved in brain waves that are pivotal for encoding memories. The findings could eventually be used to develop novel therapies for people with memory loss disorders such as Alzheimer's disease and other forms of dementia.
Memory involves both recall of specific details (who, where, when) and feelings of remembering and reliving past events. New research shows that these objective and subjective memories function independently, involve different parts of the brain, and that we make decisions based on subjective memory.
