Scientists at Kyoto University's Institute for Cell-Material Sciences have discovered a novel cluster compound that could prove useful as a catalyst. Compounds, called polyoxometalates, that contain a large metal-oxide cluster carry a negative charge. They are found everywhere, from anti-viral medicines to rechargeable batteries and flash memory devices.

Glaciers are experiencing fast and significant changes under global warming. Glacier shrinkage significantly impacts global sea level, regional water cycles, ecosystems, and natural hazards.

Just 150 fragments of staghorn coral planted off Florida's shore might give new hope to the state's endangered reefs.

Have you ever wanted to become a snake hunter in the Florida Everglades? Now's your chance.

Federal officials say the FBI's database of people prohibited from purchasing firearms only works if it has "complete, accurate and timely information."

Metro areas in the United States have become increasingly unaffordable to residents, especially Black and Latino Americans, finds a new report from the USC Dornsife Equity Research Institute (ERI), published by the National Equity Atlas.

An international research team has recently developed a new proton capture reaction rate of copper-57 for the extreme astrophysical environment at the surface of neutron stars. The researchers found that the new reaction rate changes some of the most critical nucleosynthesis paths in Type-I X-ray bursts.

Herbicide-resistant crops are now commonplace in the U.S. and Canada. With proper stewardship, these same crop-trait technologies can also play a key role in integrated weed management—reducing the intensity of herbicide use and the selection pressure on weed populations. But does this weed management potential match the reality in the field?

Land use change, like cutting down a forest to make way for agriculture, can be a major contributor to climate change by releasing greenhouse gases into the atmosphere. Researchers at the University of New Hampshire studied a practice known as silvopasture which intentionally preserves trees in pastures where livestock graze. They found that compared to a completely cleared, tree-less, open pasture, the integrated silvopasture released lower levels of carbon dioxide and nitrous oxide and soil carbon storage remained the same...

Mutual fund investors are known to be vulnerable to fluctuating market conditions. What is less well understood is how corporate managers are affected by waves of investor optimism. A researcher has published a study in the journal Financial Innovation, where he argues that corporate managers and investors are jointly caught up in market euphoria. Using a long time series of aggregate flows in and out of bond and equity mutual funds as a proxy for investor sentiment, the study's author, Thorsten Lehnert... Читать дальше...

A new analysis demonstrates that restoration of mangroves and coral reefs can be a cost-effective solution for coastal flood reduction in more than 20 countries across the Caribbean.

Holographic interferometry is the technique of measuring stress, strain, and vibration with light. It is defined by the wavelength of light, finding flaws in structural bonds. It makes full use of a hologram's ability to reproduce the optical field reflected or transmitted by an object.

Oil spills and industrial pollution pose a huge threat to the ecological environment. Concerns over safety have seen an increased focus on improving the filtration of oily wastewater; for example, during the treatment of sewage. Membrane separation technology offers a promising and efficient option for treating that wastewater, particularly with its low energy consumption. However, it remains a challenge to find low-cost, strong and environmentally-friendly composite membranes that can achieve a high level of separation.

The third dimension may be responsible for preventing electronics from becoming thinner, tinier and more flexible, according to an international collaboration that developed a way to manufacture new, idealized two-dimensional semiconductor materials. They published their approach on June 3 in Nano Research.

As industry has developed over the past century, excess carbon dioxide emission had led to climate problems and greenhouse effects. Scientists are constantly working toward solutions for the problems of greenhouse gases, which are warming the earth's surface and the lower parts of the atmosphere. Carbon dioxide is the most prevalent of the greenhouse gases.

Medical devices, cars, and many advanced technologies contain innumerable delicate components that are held together by electrically conductive polymers, such as polyaniline. For several decades, synthesis of polyaniline for industrial electronics applications has faced a major limitation: what solvent best facilitates synthesis? This abstract question is important for minimizing the cost and complexity of polyaniline production and facilitating useful properties such as shaping. The ability to use a range of cheap...

As the days get colder, teachers not only face the usual seasonal battle of keeping classrooms at a comfortable temperature but also trying to reduce the COVID-19 virus count in the environment. How to reduce virus spread is important knowledge for teachers—just as it was a century ago when the 1918 flu pandemic hit.

Incarcerated workers generate billions of dollars worth of goods and services annually but are paid pennies per hour without proper training or opportunity to build skills for careers after release, according to a comprehensive nationwide report released by the University of Chicago Law School's Global Human Rights Clinic and the American Civil Liberties Union

This month, Denver, Las Vegas and Phoenix all posted record high temperatures. And across the nation, Americans are ramping up for a scorching summer. Yet despite more frequent and intense heat waves on the horizon, cities are underprepared to deal with the challenge, according to a UCLA-led research team.

Staph infections pose lethal threats in hospitals, where the Staphylococcus aureus bacterium can be transferred from the skin or nasal passages into open wounds and, potentially, the bloodstream. The Centers for Disease Control and Prevention reported that staph infections killed nearly 20,000 Americans in 2017 alone. Antibiotic-resistant strains of S. aureus, including the notorious MRSA, present especially grave threats to patients.

A study in the Global Business and Economics Review looks at the economic and psychosocial effects of the COVID-19 pandemic on the nations of the GCC (the Gulf Cooperation Council).

A research team led by Prof. Qian Shengbang and Ph.D. student Li Fuxing from the Yunnan Observatories of the Chinese Academy of Sciences has found that the formation and evolution of the massive binaries in the Milky Way and Andromeda Galaxy (M31) may share the same mechanism.

Most of the Spanish population is pessimistic about the future climate actions by the government and citizens after the impact of COVID-19. This is the conclusion of a study carried out by researchers at the Institute of Environmental Science and Technology of the Universitat Autònoma of Barcelona (ICTA-UAB), which seeks to determine how the COVID-19 crisis has affected society's attitude toward climate change.

The concern that media access may be harmful to children and adolescents has been a topic of public debate since long before the existence of the smartphone.
