Each day, more deaths are being linked to the heat wave that struck the Pacific Northwest this past week, with medical staff who treated people overwhelmed by temperatures well above 100 degrees Fahrenheit (38 Celsius) saying the toll from the extreme weather will keep creeping up.

Hurricane Elsa churned through the Caribbean Friday, bringing powerful winds and the potential for storm surges and heavy rain.

Wander around a desert most anywhere in the world, and eventually you'll notice dark-stained rocks, especially where the sun shines most brightly and water trickles down or dew gathers. In some spots, if you're lucky, you might stumble upon ancient art—petroglyphs—carved into the stain. For years, however, researchers have understood more about the petroglyphs than the mysterious dark stain,...

For the first time in the UAE, researchers at NYU Abu Dhabi have used nuclear magnetic resonance techniques to determine the structure of a specific nanobody, Nb23, potentially leading to a better understanding of how this small protein derived from an antibody type, found only in camelids (i.e camels, llamas, and alpacas) and sharks, can fight diseases ranging from rheumatoid arthritis, lupus and...

For decades, people have wondered why pelagic red crabs—also called tuna crabs—sometimes wash ashore in the millions on the West Coast of the United States. New research shows that atypical currents, rather than abnormal temperatures, likely bring them up from their home range off Baja California.

Archaeologists have unearthed a rare trove of more than 80 metal objects in Mississippi thought to be from Hernando de Soto's 16th-century expedition through the Southeast. Many of the objects were repurposed by the resident Chickasaws as household tools and ornaments, an unusual practice at a time when European goods in North America were few and often reserved for leaders.

Research led by Kansas State University's Suprem Das, assistant professor of industrial and manufacturing systems engineering, in collaboration with Christopher Sorensen, university distinguished professor of physics, shows potential ways to manufacture graphene-based nano-inks for additive manufacturing of supercapacitors in the form of flexible and printable electronics.

A huge global network of researchers is working together to take the pulse of our global tropical forests.

Nitrogen is essential for all life on Earth. In the global oceans however, this element is scarce, and nitrogen availability is therefore critical for the growth of marine life. Some bacteria found in marine waters can convert nitrogen gas (N2) to ammonia (known as N2 fixation), and thereby supply the marine food web with nitrogen.

There are plenty of negatives associated with smart technology—tech neck, texting and driving, blue light rays—but there is also a positive: the digital age is not making us stupid, says University of Cincinnati social/behavioral expert Anthony Chemero.

A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet's core and crust). For decades, scientists argued that hit-and-run collisions with other bodies during the formation of our solar system blew away much of Mercury's rocky mantle and left the big, dense, metal core inside. But new research reveals that collisions are not...

A year after University at Buffalo scientists demonstrated that it was possible to produce millions of mature human cells in a mouse embryo, they have published a detailed description of the method so that other laboratories can do it, too.

When the U.S. Space Force's Tactically Responsive Launch-2 (TacRL-2) mission launched from Vandenberg Space Force Base on June 13, it carried a payload designed and built in record time by Lawrence Livermore National Laboratory (LLNL). 

Hot vents in the deep sea are home to microbes that feed on ethane. They were discovered recently from scientists of the Max Planck Institute for Marine Microbiology. Now the researchers from Bremen succeeded in finding an important component in the microbial conversion of the gas. They were able to decode the structure of the enzyme responsible for the ethane fixation. The structure highlights...

Originally discovered as a bacterial mode of defense against invading viruses, the remarkable ability of CRISPR-Cas9 to modify specific locations of DNA has made it a researcher favorite among gene editing tools. The ongoing effort to explore further possibilities of the CRISPR-Cas9 system is ushering in newer developments to this tool. In one of the latest refinements of the technique, as...

Dozens of fires raged across western Canada and California on Friday with little relief expected from a deadly heat wave that has seen temperatures hit record highs.

In his Ph.D. thesis, EPFL researcher Martí Bosch proposes a method for spatially quantifying the impact of mitigation measures—planting green spaces and using different building materials—on the urban heat island effect.

During the course of evolution, animals have adapted to the particular demands of their local environments in ways that increased their chances of survival and reproduction. This is also true of diverse aspects of the sensory systems that enable species to perceive their surroundings. In the case of the visual system, these adaptations have shaped features such as the positioning of the eyes and...

Plastics are a growing problem for natural ecosystems around the globe, and in particular for our marine and freshwater environments. Rivers are the leading source of plastic pollution, as it has been estimated that they deliver several million metric tons of plastic annually to our oceans from poor land-based waste management. The problem is that the estimates made for plastics flowing from the...

NIMS and Harvard University jointly developed a technique capable of measuring the viscosity of both liquids and gasses using the same device. This device can be used to identify unknown fluids based on their viscosities and may potentially be used to analyze biological fluids (e.g., breath and blood) for health monitoring and medical checkups. The device may also be used to investigate the...

The flavor of a tomato is an interaction between its taste and aroma. Now, researchers from Japan and the United States have revealed that the pigments that determine the colors of tomatoes also affect their flavor.

In the 19th century, the notorious pathogen Phytophthora infestans caused a large famine in Ireland and other parts of Western Europe. To this day, it continues to pose a major threat to global food production. It has long been a mystery how this microscopically small organism and other members of the Phytophthora genus mechanically gain entry through the protective layer on the leaves of crops....

Microorganisms produce natural products, for example, as disease-causing virulence factors or as defense substances against predators and competitors. A team led by Dr. Robin Teufel and first author Ying Duan from the Institute of Biology II at the Faculty of Biology of the University of Freiburg, together with researchers from the University of Bonn, have now discovered a novel enzyme that is...

More efficient use of phosphorus fertilizers would make it possible to meet food demand in 2050, without using more of the world's land for agriculture. This is what environmental scientists José Mogollón and colleagues have discovered by working out various future scenarios for food production and trade. This could be achieved with only 7% more phosphorus fertilizer. And if our future is more...
