Cats who suffered burns and smoke inhalation in urban California wildfires are at risk of forming deadly blood clots, according to a new study from researchers at the University of California, Davis, Veterinary Medical Teaching Hospital. The study, recently published in the journal Frontiers in Veterinary Science, follows up on a previous discovery that showed cats injured in urban wildfires had a high incidence of heart problems.

Whether it is cars, energy or mobile phones, modern society is built on metals, and our future strongly depends on these materials, too. To store hydrogen in a safe, compact and still environmentally friendly way is still a major challenge. Metal hydrides could be an appealing solution, especially for those applications where the volume and safety of the storage system is an issue—for example, in stationary storages, in hydrogen refueling stations or ships—as they can provide a very high storage density.

Post-it Notes, Spanx, the iPhone, two-day Prime shipping. From unique gadgets to revolutionary business ideas, the most successful inventions have one thing in common: creativity. But sustaining creativity can be difficult.

For well over a century the immense biodiversity of the lands that constitute Spain's Doñana National Park has attracted the attention of hunters, nature-lovers, and natural scientists from across the Western world. Iberian lynx, fallow and red deer, wild boar, badgers, and vast flocks of migratory and endemic birds thrived in wetlands, dunes, and forests, which have collectively long been considered one of the wildest and most ecologically significant spaces in Western Europe.

The State of California is banking on its forests to help reduce planet-warming carbon dioxide in the atmosphere. But that element of the state's climate-change solution arsenal may be in jeopardy, as new research from the University of California, Irvine reports that trees in California's mountain ranges and open spaces are dying from wildfires and other pressures—and fewer new trees are filling the void.

In recent years, many Americans have begun to rethink their views on racial justice and the prejudice that exists within our country. But as white Americans confront others who are spewing prejudice, how does that impact Black Americans?

In the Standard Model of particle physics, the Brout-Englert-Higgs mechanism provides mass to elementary particles. While physicists are carrying out direct studies of the Higgs boson to test this mechanism, probes of other particles that have mass can also provide insight. For instance, the W and Z bosons—the carriers of the weak force—get their mass from the Higgs mechanism. This impacts their polarization, that is, the degree by which their quantum spin is aligned to a given direction. The W and... Читать дальше...

The genetic evolution of freshwater fish in Ecuador could unlock new insights for conservation ecologists. A new collaboration between biologists and computer scientists at DePaul seeks to sequence the genomes of these species.

The question of how the chemical composition of a protein—the amino acid sequence—determines its 3D structure has been one of the biggest challenges in biophysics for more than half a century. This knowledge about the so-called "folding" of proteins is in great demand, as it contributes significantly to the understanding of various diseases and their treatment, among other things. For these reasons, Google's DeepMind research team has developed AlphaFold, an artificial intelligence that predicts 3D structures.

A strain-sensing smart skin developed at Rice University that uses very small structures, carbon nanotubes, to monitor and detect damage in large structures is ready for prime time.

A novel peptide developed at the Universities of Bayreuth and Bristol is eminently suited for the targeted transport of molecules⁠—for example, of active substances and dyes⁠—into the cells of mammals. The peptide is characterized by a dual function: It can enter the cell from the outside and interact there with a partner peptide. The partner peptide must have previously been placed inside the cell exactly where the transported molecules are to take effect. The transport system presented in the journal... Читать дальше...

In the deep subsurface that plunges into the Earth for miles, microscopic organisms inhabit vast bedrock pores and veins. Belowground microorganisms, or microbes, comprise up to half of all living material on the planet and support the existence of all life forms up the food chain. They are essential for realizing an environmentally sustainable future and can change the chemical makeup of minerals, break down pollutants, and alter the composition of groundwater.

A year after health officials issued a record number of alerts for high ozone levels on Colorado's Front Range, federal and state officials are trying to rein in the gas that can make outdoor activities a health risk.

Although dogs do not require healthy fruits in their diets as we do, giving your furry friend some of these treats may be beneficial for their health.

Dog treats are being voluntarily recalled due to possible salmonella contamination.

Loss of the Y chromosome in blood cells of men is associated with disease and mortality, but no clear, causal relationship has been identified. Now, researchers from Uppsala University show in an international study in the journal Science that loss of the Y chromosome in white blood cells causes development of fibrosis in the heart, impaired heart function and death from cardiovascular diseases in men.

Livestock diseases will be better managed by incorporating the behaviors of individual farmers into national infection control policies, according to new research.

The high heat and low water conditions produced by global warming weaken pine trees' resistance to disease by hindering their ability to mount an effective defense at the same time that pathogenic fungi in their tissues become more aggressive, new research suggests.

Over recent decades, coastal cities in the U.S. have experienced significant increases in floods that occur during high tide, which create dangerous driving conditions, road closures, groundwater contamination and other safety issues. Climate change and sea level rise have facilitated more of these high-tide floods, according to new research in AGU's Journal of Geophysical Research-Oceans.

Since the launch of the first man-made earth satellite, the number of space objects has been rapidly increasing. According to the authoritative statistics from NASA, over 6,400 orbiting spacecraft still existed until early 2021. Furthermore, the total number of rocket debris above 10 cm has exceeded 16,000. The space environment has become highly congested due to the increasing space debris, seriously threatening the safety of orbiting spacecraft.

Distortion and Holocaust denial is present on all social media platforms, but moderation and education can significantly reduce this, according to a landmark report today from UNESCO and the United Nations, supported by analysis by researchers from the Oxford Internet Institute.

Early in 2022, the French legislature greenlighted the cultivation of cannabis inside French territory to supply the nation's ongoing pilot program in medical marijuana. The clinical trials were launched in March 2021 with cannabis supplied from abroad and have been overseen by the country's food and drug office, the Agence Nationale de Sécurité du Médicament, or the National Agency for the Safety of Medicines and Health Products.

Salmon lice are one of the biggest challenges for the Norwegian aquaculture industry today and pose a threat to wild salmon. The authorities have therefore introduced several measures to reduce the lice levels in production facilities and the infection pressure on wild fish.

Eight in 10 U.S. workers say that how employers support their employees' mental health will be an important consideration when they seek future job opportunities, while 71% believe their employer is more concerned about the mental health of employees now than in the past, according to a survey from the American Psychological Association.
