Residents of public housing throughout the United States experience higher levels of air pollution, according to an inter-institutional study led by a researcher from The University of Texas at El Paso that appeared in Scientific Reports.

To human eyes, the night sky between the stars appears dark, the void of space. But X-ray telescopes capture a profoundly different view. Like a distant fireworks show, our images of the X-ray sky reveal a universe blooming with activity. They hint at yet unknown cosmic eruptions coming from somewhere deeper into our galaxy.

Assembly of HIV-1, which causes AIDS, takes place on the inner plasma membrane leaflet of infected cells, a geometric building process that creates hexamers out of trimers of the viral Gag protein, as guided by Gag's N-terminal matrix domain.

The mission's team has chosen to operate its seismometer longer than previously planned, although the lander will run out of power sooner as a result.

Animals—both herbivores and predators—follow their noses for a broad range of food sources. The principle applies to hunters trying to ferret out easy prey or grazers searching for the richest plants.

Cannabis, a plant gaining ever-increasing attention for its wide-ranging medicinal properties, contains dozens of compounds known as cannabinoids.

It's hard to forget the excruciating heat that blanketed the Pacific Northwest in late June 2021. Temperatures in Oregon, Washington and British Columbia soared to well above 100 degrees Fahrenheit, with Seattle setting an all-time heat record of 108 degrees on June 28.

Synthetic dimensions in photonics offer exciting new ways to manipulate light, to study physical phenomena with exotic connectivities, and explore higher-dimensional physics. Dynamically modulated ring resonator systems, where resonant modes are coupled to construct a synthetic frequency dimension, can provide great experimental flexibility and reconfigurability.

Researchers at the University of Jyväskylä, Finland, have found that the larvae of freshwater pearl mussel survive best in the original salmon fish population of their home river. Their study was published in Freshwater Biology.

A new study from The University of Western Australia has challenged earlier claims that Aboriginal stone artifacts discovered off the Pilbara coast in Western Australia represent Australia's first undisturbed underwater archaeological site.

The gelatin in the skin of Pacific whiting, an abundant fish on the Pacific Coast of North America, may help prevent skin wrinkling caused by ultraviolet radiation, a new Oregon State University study found.

Rensselaer Polytechnic Institute researchers have developed an accessible way to make N95 face masks not only effective barriers to germs, but on-contact germ killers. The antiviral, antibacterial masks can potentially be worn longer, causing less plastic waste as the masks do not need to be replaced as frequently.

NASA's fourth attempt to complete a critical test of its Moon rocket achieved around 90 percent of its goals, but there's still no firm date for the behemoth's first flight, officials said Tuesday.

The extremely salty, very cold, and almost oxygen-free environment under the permafrost of Lost Hammer Spring in Canada's High Arctic is the one that most closely resembles certain areas on Mars. So, if you want to learn more about the kinds of life forms that could once have existed—or may still exist—on Mars, this is a good place to look. After much searching under extremely difficult...

It's a given that certain bacteria and viruses can cause illness and disease, but the real culprits are the sequences of concern that lie within the genomes of these microbes.

A state's risk of a coup is negatively associated with its army's degree of mechanization, understood as the extent to which militaries depend on tanks and armored vehicles in relation to personnel.

Researchers have identified how the bacterium that causes tuberculosis (TB) can evolve rapidly in response to new environments, according to a study published today in eLife.

Heavy rainstorms are causing major flooding and landslides in southern China, destroying buildings, crops and roads, and forcing many people to flee their homes.

The sex and sexual characteristics constitute key aspects of an organism's life and are determined by a biological process known as sex determination. These ever-evolving mechanisms are broadly classified based on the type of "switch" that triggers them. Genetic sex determination is dependent on sex chromosomes, such as the X and Y chromosomes in human beings, whereas environmental sex...

Distilling liquor might be a relatively simple process—heating a fermented liquid and keeping only the boiled alcohol—but it is dangerous and illegal without a license.

Silk has been cultivated for centuries by domesticated silkworms, but it has been difficult to commercially produce spider silk in bulk due to their cannibalistic tendencies. However, spider silk fibers are attracting attention for their fineness, mechanical properties, and lustrous appearance. Spider silk produced through recombinant protein expression systems and chemical synthesis has been...

Everyone remembers those old high school movies where the ultra-nerdy teenage boy falls in love with a the most beautiful girl in the whole school. The movie begins with the girl not knowing anything about the geeky leading man that most wouldn't consider a strong partner, but by the end, she's fallen for him too. It's a classic romantic movie formula.

Quantum sensors, which detect the most minute variations in magnetic or electrical fields, have enabled precision measurements in materials science and fundamental physics. But these sensors have only been capable of detecting a few specific frequencies of these fields, limiting their usefulness. Now, researchers at MIT have developed a method to enable such sensors to detect any arbitrary...

A new SwRI study describes how unique populations of craters on two of Saturn's moons could help indicate the satellites' age and the conditions of their formation. Using data from NASA's Cassini mission, SwRI postdoctoral researcher Dr. Sierra Ferguson surveyed elliptical craters on Saturn's moons Tethys and Dione for this study, which was co-authored by SwRI Principal Scientist Dr. Alyssa...
