NASA-NOAA's Suomi NPP satellite captured night-time look at Hurricane Irma as it weakened to a large tropical storm and the GOES East satellite provided a daytime view as the large storm continued moving north over Florida.

A 52-million-year-old ankle fossil suggests our prehuman ancestors were high-flying acrobats.

These first primates spent most of their time in the trees rather than on the ground, but just how nimble they were as they moved around in the treetops has been a topic of dispute.

For years, scientists thought the ancestors of today’s humans, monkeys, lemurs and apes were relatively slow and deliberate animals, using their grasping hands and feet to creep along small twigs and branches to stalk insects or find flowers and fruits.

Operation IceBridge is flying in Greenland to measure how much ice has melted over the course of the summer from the ice sheet. The flights, which began on Aug. 25 and will go on until Sept. 21, repeat paths flown this spring and aim to monitor seasonal changes in the elevation of the ice sheet.

As Hurricane Irma bears down on the U.S., the MIT Urban Risk Lab has launched a free, open-source platform that will help residents and government officials track flooding in Broward County, Florida. The platform, RiskMap.us, is being piloted to enable both residents and emergency managers to obtain better information on flooding conditions in near-real time.

Southern cities such as Houston and Tampa — which faced the wrath of hurricanes Harvey and Irma, respectively — may not be the only urban environments vulnerable to extreme weather. Northern cities also face the potential for flooding as global temperatures continue to warm.

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.

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.

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'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.

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.
