Devastating wildfires that have ravaged the US West Coast continued to rage on Wednesday as smoke from the deadly blazes spread across the country and even reached Europe.

Researchers have developed an automated 3-D printing method that can produce multicolor 3-D microstructures using different materials. The new method could be used to make a variety of optical components including optical sensors and light-driven actuators as well as multimaterial structures for applications such as soft robotics and medical applications.

A sustained dialogue must be established between molecular ecologists, policymakers and other stakeholders for DNA-based approaches to be adopted in marine monitoring and assessment, according to KAUST scientists and colleagues.

NASA-NOAA's Suomi NPP satellite passed over the South China Sea and captured a visible image of Tropical Storm Noui as it continued to organize and intensify.

Entire wildlife areas have been destroyed and endangered populations of animals gravely depleted by wildfires burning in Eastern Washington.

Diversity in many biological communities is a sign of an ecosystem in balance. When one species dominates, the entire system can go haywire. For example, the uncontrolled overgrowth of certain oceanic algae species causes toxic red tides that kill fish and other sea life, and sicken humans. On a more individual level, the human gut hosts a large community of different bacteria that is crucial for...

Tropical Storm Karina was making night moves like the old Bob Seger song. NASA-NOAA's Suomi NPP satellite provided an infrared image of Tropical Storm Karina's nighttime movement as it moved away from the Baja California peninsula of Mexico. Infrared data showed the storm was weakening.

Tropical cyclones can become post-tropical before they dissipate, meaning they can become sub-tropical, extra-tropical or a remnant low-pressure area. As Hurricane Paulette transitioned into an extra-tropical storm, NASA's Terra satellite provided a visible image of the powerful storm, and the National Hurricane Center issued their final advisory on the system.

Chat with an atmospheric scientist for more than a few minutes, and it's likely they'll start advocating for a planetary name change. Planet Ocean-Cloud is much more fitting than Earth, they'll say, when so much of our planet's life systems are affected by the interactions of clouds and the oceans.

NASA analyzed the cloud top temperatures in Hurricane Teddy using infrared light to determine the strength of the storm. Infrared imagery revealed that the strongest storms were on Teddy's western side.

Around 120,000 years ago in what is now northern Saudi Arabia, a small band of homo sapiens stopped to drink and forage at a shallow lake that was also frequented by camels, buffalo and elephants bigger than any species seen today.

Researchers have compiled a new database of tweets from parliament members from 26 European countries and illustrated how this resource could help address challenges in the burgeoning field of Twitter research. Livia van Vliet of the University of Amsterdam, Netherlands, and colleagues present the new database and findings in the open-access journal PLOS ONE on September 16, 2020.

A simple manufacturing technology based on chitin, one of the most ubiquitous organic polymers on Earth, could be used to build tools and shelters on Mars, according to a study published September 16 in the open-access journal PLOS ONE by Javier Fernandez of Singapore University of Technology and Design, and colleagues.

A new study of older pet dogs found that problem solving, sociability, boldness and dependency decline with age, and reported no associations between an enriched diet, lifelong training experiences, and measures of behavior and cognition after a one-year diet period. A team of researchers at the University of Veterinary Medicine, Vienna, Austria, and University of Liverpool, UK present these...

Researchers at the University of Washington, Portland State University and the University of Oregon have shown that deep-seated landslides in the central Oregon Coast Range are triggered mostly by rainfall, not by large offshore earthquakes.

The painful toxins wielded by a giant Australian stinging tree are surprisingly similar to the venom found in spiders and cone snails, University of Queensland researchers have found.

For more than 1 million years, independent cavefish populations that are geographically and hydrologically isolated from one another have evolved to include about 29 different populations. Among them, the tiny Mexican tetra, Astyanax mexicanus, which comprises river-dwelling surface fish and multiple independently evolved populations of blind cavefish. Many of the behaviors between these cavefish...

Vibrations in the ground may help to improve advanced warnings about sudden floods that result from glacial melting, according to a study published today in Science Advances.

It's not often a new mass extinction is identified; after all, such events were so devastating they really stand out in the fossil record. In a new paper, published today in Science Advances, an international team has identified a major extinction of life 233 million years ago that triggered the dinosaur takeover of the world. The crisis has been called the Carnian Pluvial Episode.

176,500 metric tons of synthetic microfibers—chiefly polyester and nylon—are released every year onto terrestrial environments across the globe, according to a new study in the open access journal PLOS ONE by Jenna Gavigan and colleagues at the University of California at Santa Barbara. The microfibers are shed from clothing during washing, and the amount ending up on land now exceeds the...

Hurricane Sally lumbered ashore near the Florida-Alabama line Wednesday with 105 mph (165) winds and rain measured in feet, not inches, swamping homes and trapping people in high water as it crept inland for what could be a long, slow and disastrous drenching across the Deep South.

Minnesota and Midwestern moose will not be listed as a federally endangered species, putting to bed a petition that's been under review for five years.

A team of researchers from North Carolina State University has demonstrated a way to use low-energy, visible light to produce polymer gel objects from pure monomer solutions. The work not only poses a potential solution to current challenges in producing these materials, it also sheds further light on the ways in which low energy photons can combine to produce high energy excited states.

Along three scenic drives through Colorado's Rocky Mountains in fall, tourists will see less of a brilliant golden tree in the next 100 years, researchers from North Carolina State University projected in a new study.
