A review of more than 100 studies finds that swearing helps people tolerate pain, ease stress, build and maintain interpersonal connections, and in some cases, be more persuasive.
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...
Based on a false sense of security, students who participated in frequent COVID-19 testing at two universities engaged in more behavior known to increase the risk of spreading the virus than they might have otherwise, according to results of surveys.
New data from an international research team adds another dimension -- literally -- to understanding the economic and environmental impacts of how cities are built. Using satellite mapping, researchers measured the height of built-up infrastructure in urban areas across the globe, which could improve projections of energy use and emissions and inform city planning and economic development efforts,...
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 high-profile sexual harassment case 7 years ago in California is now reverberating in Europe, with implications for those who speak out against the unsavory academic practice of “passing the harasser.” In February 2018, two astrophysicists at the University of Helsinki, Syksy Räsänen and Till Sawala, spearheaded an open letter from more than 70 Finnish astronomers and...
A new study measures how spatial, temporal, cognitive, and cultural limitations affect humans' understanding of their environments.
Most Americans report experiencing at least one traumatic event in childhood, and a new study shows that these experiences have significant impacts on our health risks as adults. Physical illnesses such as obesity and chronic pain are affected, but mental disorders show the most significant association, including post-traumatic stress disorder (PTSD), bipolar disorder, substance abuse, and...
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. After observing these results with a short-term intervention, the research team plans to progress to similar studies in people.
A new study conducted in England shows that the risk of death due to COVID-19 remains very low for children and young people, and most deaths occur in those with underlying health conditions.
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,...

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.
For centuries, Indigenous communities in the American Southwest imported colorful parrots from Mexico. But according to a recent study, some parrots may have been captured locally and not brought from afar. The research challenges the assumption that all parrot remains found in American Southwest archaeological sites have their origins in Mexico. It also presents an important reminder: The ecology...
While the physical differences between humans and non-human primates are quite distinct, a new study reveals their brains may be remarkably similar. And yet, the smallest changes may make big differences in developmental and psychiatric disorders.
Aerospace and mechanical engineers have developed a machine-learning assisted superfast new way to create high-performance, energy-saving thermoelectric devices.
Federal subsidies promote planting cover crops to store carbon in agricultural soils, among other benefits, but the approach as currently practiced can reduce yields in the U.S. Corn Belt, researchers find. Their analysis highlights the need to better implement the practice.
MACHETE is a new CRISPR-based technique developed to study large-scale genetic deletions efficiently in laboratory models.
An experiment carried out across ten workplace cafeterias found no significant change in the overall number of calories purchased when food and drink labels showed the amount of physical activity required to burn off their calories.
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.
