Scientists used data gathered by NASA's Cassini spacecraft during 13 years of exploring the Saturn system to make detailed images of the icy moon—and to reveal geologic activity.

Smoke from California and Oregon wildfires has cloaked Canada's third-largest city of Vancouver—known for its majestic mountain views and fresh ocean breezes—in the dirtiest air in the world this week.

Meteorologists were forced to break out the Greek alphabet Friday to name Atlantic storms for only the second time ever after the 2020 hurricane season blew through their usual list, ending on Tropical Storm Wilfred.

Points matter when designing nanoparticles that drive important chemical reactions using the power of light.

State and federal authorities are investigating the mysterious loss of a significant swath of a rare desert wildflower that's being considered for federal protection at a contentious mine site in Nevada with some of the largest untapped lithium deposits in the world.

Six years after it began, the Flint, Michigan, water crisis remains among the highest-profile emergencies in the United States.

The list of hurricane names is officially used up with the development of the 23rd tropical cyclone of the year. Tropical Storm Wilfred just formed in the Eastern Atlantic Ocean today, Sept. 18. Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Wilfred's rainfall rates.

Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Hurricane Teddy's rainfall rates. Teddy is a major hurricane in the Central North Atlantic Ocean.

NASA-NOAA's Suomi NPP satellite provided an infrared image of Tropical Depression 22 in the Gulf of Mexico during the early morning hours of Sept. 18. TD22 is expected to become a tropical storm, according to the National Hurricane Center (NHC).

Tropical Storm Noul made landfall in central Vietnam on Sept. 17 and NASA-NOAA's Suomi NPP satellite captured an image of the storm over Laos. Noul was weakening as it moves toward Thailand where it is forecast to dissipate.

Subtropical Storm Alpha has formed near the coast of Portugal, becoming the first named storm using the Greek Alphabet list, now that the annual list of names is exhausted. NASA's Aqua satellite obtained visible imagery of the new storm.

Researchers observed three chimpanzee communities of the Tai National Park. They kept full demographic records and collected fecal samples to conduct paternity tests on all new community members, for up to 30 years. Catherine Crockford, the lead author, says: "When we study our closest living relatives, like chimpanzees, we can learn about the ancient environmental factors that made us human. Our...

The removal of one gene renders poxviruses—a lethal family of viral infections that are known to spread from animals to humans—harmless, a new study in the journal Science Advances reports.

Large volcanic eruptions can help to forecast monsoons over India. This seasonal rainfall is key for the country's agriculture and thus for feeding 1 billion people. As erratic as they are, volcanic eruptions improve the predictability, an Indian-German research team finds. What seems to be a paradox is, in fact, due to a stronger coupling between the monsoon over large parts of South and...

Flooding has affected well over a million people across East Africa, another calamity threatening food security on top of a historic locust outbreak and the coronavirus pandemic.

As our lives become increasingly intertwined with technology—whether supporting communication while working remotely or streaming our favorite show—so too does our reliance on the data these devices create. Data centers supporting these technology ecosystems produce a significant carbon footprint—and consume 200 terawatt hours of energy each year, greater than the annual energy consumption...

A new hollow optical fiber greatly reduces the "noise" interfering with the signals it transmits compared to the single-mode fibers now widely used, researchers at the University of Rochester report.

Astronomers using the National Science Foundation's Very Long Baseline Array (VLBA) have made the first direct geometric measurement of the distance to a magnetar within our Milky Way Galaxy—a measurement that could help determine if magnetars are the sources of the long-mysterious Fast Radio Bursts (FRBs).

In the past decade, researchers have engineered an array of new tools that control the balance of genetic inheritance. Based on CRISPR technology, such gene drives are poised to move from the laboratory into the wild where they are being engineered to suppress devastating diseases such as mosquito-borne malaria, dengue, Zika, chikungunya, yellow fever and West Nile. Gene drives carry the power to...

Global maps of places where people and forests coexist show that an estimated 1.6 billion people live within 5 kilometers of a forest. The assessment, based on data from 2000 and 2012 and published September 18 in the journal One Earth, showed that of these 1.6 billion "forest-proximate people," 64.5 percent were located in tropical countries, and 71.3 percent lived in countries classified as low...

Research has found a proposal to regulate mining of Indigenous lands in Brazil's Amazon rainforest could affect more than 863,000 square kilometers of forest and harm the nation's economy.

On July 26, Svalbard's only active coal mine, Gruve 7, was reported to be flooded by its operators, Store Norske Spitsbergen Kulkompani. It had been shut down earlier this year due to the ongoing COVID-19 pandemic; now plans to reopen the mine will now be delayed even further as a result. Glacial meltwater entered the mine through a crevasse at the junction between the overlying ice cap and...

Each September, scientists like me look out for the point when the Arctic's meager summer fizzles out and sea ice begins to grow once more. This point is known as the annual sea ice minimum extent. It has declined consistently over the past 15 years, and 2019 was the second lowest after 2012 in 42 years of continuous satellite records. This year's minimum is imminent, and there is already even...

You can feel it on your laptop and mobile phone. It's behind your refrigerator and office copy machine. While heat is desirable for appliances like a coffee maker, it can jeopardize the reliability and safety of electronic systems in other devices, causing premature failure at best and explosions at worst.
