Three days after Hurricane Fiona struck Puerto Rico in mid-September, the National Weather Service issued an extreme heat advisory, warning that the heat index—which incorporates humidity to calculate perceived temperature—could reach up to 109 degrees.

Dwarfed by its more prestigious sibling, the Amazon, South America's second largest forest is a little-known victim of 25 years of gradual invasion by agriculture.

The effects of climate change on tropical regions are still poorly understood. However, tropical regions are among the most populated areas in the world. Researchers at the Leibniz Institute for Applied Geophysics (LIAG) have now created both an age-depth model and a moisture distribution for the last 500,000 years from one of the oldest lakes in central Mexico, Lake Chalco.

If there's news about amphibians these days, odds are it's not going to be good. A pathogenic fungus has been decimating populations around the world for about forty years and counting, pushing many species to extinction. Once a species is classified as extinct, odds are it isn't coming back.

Large asset managers holding shares in multiple companies across the same industry are often accused of hurting competition through the substantial concentration of ownership in the hands of a relative few. Investors such as BlackRock, Vanguard and State Street fall into this camp, controlling 90% of U.S. publicly traded firms in 2018.

For at least 200,000 years, we humans have been trying to understand our environments and adapt to them. At times, we have succeeded; often, we have not. When we get it wrong—through anthropogenic exacerbations leading to the Dust Bowl and the growth of the dead zone in the Gulf of Mexico—the results can be disastrous. However, in both success and failure, we can learn from our past...

When it comes to preventing tick bites—especially in light of the dramatic, decade-long rise in tick-borne diseases—bug sprays help but are less than optimal.

A few years ago, scientists discovered a curious case of protozoa (oxymonads) that do not have mitochondria. Since then, the research group of Associate Professor Hampl from the Faculty of Science of Charles University and the BIOCEV research center has been asking how the unique loss of mitochondria occurred.

The United Nation's 27th annual climate summit, COP27, opened on Monday in Sharm el-Sheikh, Egypt. The event, which should pressure governments into ramping up their decarbonization pledges, will be the first to put the issue of financial compensation for damages suffered by developing countries at the top of the agenda. What is at stake and who are the movers and shakers of climate finance?

Humans have the highest prenatal growth rate of all extant primates, but how this exceptional rate came about has been a mystery up to now. Leslea Hlusko, a scientist at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), has participated in a study led by Tesla Monson, a paleoanthropologist at Western Washington University (WWU) in the United States), looking at teeth,...

Two weeks of eating a diet heavy in tomatoes increased the diversity of gut microbes and altered gut bacteria toward a more favorable profile in young pigs, researchers found.

As the COVID-19 pandemic settled in over the course of the first half of 2020, few works enjoyed as much renewed interest as those of the Algerian-born French existentialist Albert Camus. His classic 1947 novel "The Plague" tells the story of a town beset and isolated by an outbreak of the bubonic plague. The plague drags on and health authorities struggle to contain it. The population experiences...

The COVID-19 pandemic forced everyone to reexamine their priorities. Local governments were no exception, and a new study from the University of Kansas has found that while the pandemic did cause municipalities to adjust their focus on sustainability efforts, it did not devastate them, and in some cases, caused cities to put new emphasis on certain types of sustainability initiatives.

Studying the parental behaviors of termites has provided a University of Florida scientist with a rare look into how a queen and king pair push the limits of parenthood.

Tiger Beach in the Bahamas is famous for its paradisiacal beauty and for being frequented by an animal that might scare most people away but is actually an outstanding diving tourism attraction: the Tiger shark (Galeocerdo cuvier). The sea is crystal clear and only 5 m deep on average, so the sharks, which can surpass 3 m in length, can easily be seen. They are drawn to the site by local tour...

A new study led by ISGlobal and IGTP uses a mouse model with human liver cells to characterize proteins associated with the latent form of the malaria parasite Plasmodium vivax. The findings lay the groundwork for identifying biomarkers of latent malaria vivax infections and moving forward in eliminating the disease.

More than half of charitable giving via payment apps is "forgotten" as soon as a fundraiser leaves according to a new University of Copenhagen study published in the Journal of Economic Behavior & Organization. On the other hand, digital solutions make it easier to donate more than spare change.

The summer of 2022 brought extreme heat over most of the Eurasian continent and North America. This abnormal warming led to extraordinarily long-lasting extreme heat waves, especially in Europe and China. Because of this extreme heat, a research team has undertaken a review of the recent achievements in the study of heat waves.

20 years ago, Danish chemist Morten Meldal discovered a new method for assembling molecules.

Biodegradable microplastic particles in soils can lead to an increased rise in CO2 emissions to the Earth's atmosphere. This is shown by an interdisciplinary study published in Applied Soil Ecology by the Collaborative Research Centre 1357 "Microplastics" at the University of Bayreuth. In this study, experts in soil ecology and ecological microbiology compare the effects of a conventional and a...

The promise for American agriculture is tantalizing: healthier soil, more carbon kept in the ground, less fertilizer runoff, and less need for chemicals. The reality of planting cover crops during the off-season—a much-touted and subsidized approach to climate change mitigation—is more complicated, according to new Stanford University-led research.

Racism is often debated, discussed and analyzed in politics, the classroom and the workplace.

On July 5, the LHC roared to life for its third run after three years of continual improvements to the machine as well as to the experiments' detectors and analysis tools, and immediately reached a record energy of 13.6 TeV. Just three weeks later, the compact muon solenoid (CMS) collaboration was ready for its physics data-taking period.

Universitat Autònoma de Barcelona (UAB) researchers have developed a magnetic material capable of imitating the way the brain stores information. The material makes it possible to emulate the synapses of neurons and mimic, for the first time, the learning that occurs during deep sleep.
