How Liver Cancer Develops

Liver cancer is the second-leading cause of cancer-related death and represents the fastest rising cancer worldwide. In most cases, the tumor develops in patients with chronic liver disease. Such diseases include chronic infections with hepatitis viruses or a so-called fatty liver due to nutritional or genetically caused lipometabolic disorders or an excessive consumption of alcohol.

NASA Analyzes Hurricane Jose's Hidden Cloud-Filled Eye

NASA satellite imagery provided a couple of views of Hurricane Jose's cloud-filled eye allowing forecasters to see that it still existed. NASA-NOAA's Suomi NPP satellite provided a visible look at the storm, while the GPM satellite provided a deeper look under the high clouds that were covering the eye.

Biodiversity Proves Its Real-World Value

Hundreds of experiments have shown biodiversity fosters healthier, more productive ecosystems. But many experts doubted whether these experiments would hold up in the real world. A Smithsonian and University of Michigan study published today in the journal Nature offers a decisive answer: Biodiversity’s power in the wild does not match that predicted by experiments—it surpasses it.

New Research May Improve Communications During Natural Disasters

Storms like Hurricane Irma and other natural disasters bring with them lots of uncertainty – where will they go, how much damage will they cause. But, what is certain is that no matter where they strike, natural disasters knock out power.

NASA Tracking Tropical Storm Talim in Philippine Sea

NASA's Terra satellite passed over Tropical Storm Talim early on Sept. 11 and obtained a visible-light image of the storm as it moved through the Philippine Sea.

NASA Sees Hurricane Irma Affecting South Florida

As Hurricane Irma approached southern Florida, a NASA satellite captured a night-time image of the storm in the Florida Straits and identified where the strongest storms were occurring within Irma's structure. NOAA's GOES satellite provided a visible image at the time of Irma's landfall in the Florida Keys.

10 greatest sightings, so far, from NOAA's exploration of the deepwater Pacific

Today, the NOAA Ship Okeanos Explorer is embarking on the last leg of NOAA’s three-year mission to explore the deep Pacific Ocean when it heads to the Musicians Seamounts and the Hawaiian Islands.

Starting September 7, you, too, can join the expedition virtually by following the live video streamed by a remotely operated vehicle (ROV) diving down to the seafloor near Musicians Seamounts. Dives will continue through September 29, usually between 2:00 p.m.–12:00 a.m. Eastern, depending on weather and ocean conditions.

Fishing in the Arctic

As the Arctic warms twice as fast as the rest of the planet, the range and distribution of at least some fish stocks found in places like the Bering Sea will likely extend northward. That could bring some big changes to the region. More than 60 percent of all seafood caught in the United States comes from the waters off Alaska and generates billions of dollars in revenue each year.

As previously ice-covered areas of the Arctic become seasonally ice-free, there will be pressure to expand US fishing north of the Bering Strait. That can’t happen under the Arctic Management Plan, established in 2009, which prohibits commercial fishing until scientists and fisheries managers understand what’s going on with the ecosystem.

MEXICO CITY'S EARTHQUAKE ALERT WORKED. THE REST OF THE COUNTRY WASN'T SO LUCKY

"Alerta sísmica! Alerta sísmica!" Few things strike as much fear into the hearts of Mexico City residents as the words “seismic alert” blaring from speakers in schools and parks. It means an earthquake is rumbling up from the Pacific coast, and you have 60 to 90 seconds to get someplace safe.

Heat stress escalates in cities under global warming

Heatwaves are intensifying in cities due to the double whammy of the urban heat island effect and global warming, according to a new study.
