The thirteenth tropical depression of the Atlantic Ocean season formed today, Oct. 21 and NOAA's GOES-East satellite captured its development. NASA's GOES Project created an animation from the NOAA satellite imagery that shows the depression's development over three days.

NASA will conduct a sounding rocket launch at 2 p.m. EDT, Monday, Oct. 21, 2013, from the White Sands Missile Range in New Mexico carrying an experiment to support the calibration of the EUV Variability Experiment, or EVE, aboard the Solar Dynamics Observatory, or SDO, satellite. EVE measures the total extreme ultraviolet output of the sun, called its irradiance.
ANN ARBOR, Mich. – Most parents would love to get an e-mail response from their kids' health care provider for a minor illness rather than making an office visit, but about half say that online consultation should be free, according to a new University of Michigan C.S. Mott Children's Hospital National Poll on Children's Health.
A quick glance at a world precipitation map shows that most tropical rain falls in the Northern Hemisphere. The Palmyra Atoll, at 6 degrees north, gets 175 inches of rain a year, while an equal distance on the opposite side of the equator gets only 45 inches. Scientists long believed that this was a quirk of the Earth's geometry – that the ocean basins tilting diagonally while the planet spins pushed tropical rain bands north of the equator. But a new University of Washington study shows that the pattern arises from ocean currents originating from the poles, thousands of miles away.
Typhoon Francisco passed west of Guam on Oct. 18 as NASA and the Japan Space Agency's TRMM satellite passed overhead and measured its heavy rainfall. Francisco is forecast to intensify into a super typhoon.
Francisco developed in the Western Pacific Ocean on October 16, 2013. The Tropical Rainfall Measuring Mission satellite called TRMM passed over on October 18, 2013 at 1002 UTC/6:02 a.m. EDT when Typhoon Francisco was located west-northwest of Guam.
Powerful Typhoon Wipha never made landfall in the northwestern Pacific but affected several land areas there as seen by NASA's Aqua and Terra satellites. By Oct. 18, extra-tropical storm Wipha moved into the Bering Sea and was bringing rains, warmer temperatures and gusty winds to Alaska.
CAMBRIDGE, Mass-- A central topic in spoken-language-systems research is what's called speaker diarization, or computationally determining how many speakers feature in a recording and which of them speaks when. Speaker diarization would be an essential function of any program that automatically annotated audio or video recordings.
Shuangyashan is a coal mining prefecture-level city located in the eastern part Heilongjiang province, People's Republic of China, bordering Russia's Khabarovsk and Primorsky krais to the east. Since China is known to have underground coal fires it is not unreasonable to posture that the fires seen on this satellite image might be from coal seam fires. The number of coal fires burning under the Earth's surface at any given time is not known, but it is reasonable to assume that anywhere that coal is present, fire may be as well.
The Indian state of Punjab has two growing seasons—one from May to September and another from November to April. In November, Punjab farmers typically sow crops such as wheat and vegetables; but before they do that, farmers often set fire to fields to clear them for planting. That was probably the case on October 18, 2013, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured this natural-color image.
While consumption of soda and other sugary drinks among young children in California is starting to decline, a new study released today shows an alarming 8 percent spike among adolescents, the biggest consumers of these beverages.
Tropical Depression 15-E formed on Oct. 12 at 11 p.m. EDT and strengthened into Tropical Storm Octave. Four days later NASA's Terra satellite saw the weakened storm headed for landfall in western Mexico.
TD15-E formed about 470 miles/755 km south of the southern tip of Baja California, near 16.1 north and 110.2 west. By 5 a.m. EDT on Oct. 13, TD15-E became Tropical Storm Octave. Octave's maximum sustained winds peaked at 65 mph/100 kph at 11 p.m. EDT on Oct. 13 when it was about 215 miles/345 km northwest of Socorro Island, near 20.6 north and 113.7 west.
Tropical Storm Priscilla lived just 3 days in the eastern Pacific Ocean making for one of the shortest-lived tropical storms of the season.
Priscilla skipped the depression phase and went from a low pressure area to a full-blown tropical storm at 5 a.m. EDT/0900 UTC on Oct. 14. Priscilla formed near 14.3 north and 115.7 west, about 705 miles/1,135 km southwest of the southern tip of Baja California. Priscilla moved north-northeast and had maximum sustained winds near 40 mph/65 kph at birth.
NASA's Aqua satellite passed over Typhoon Francisco on Oct. 17 after it had passed the eastern side of Guam and started to head on a track that would take it past the western side of Guam. Tropical Storm Warnings are in effect for Guam on Oct. 17 and 18 (local time).
A simple, color-coded system for labeling food items in a hospital cafeteria appears to have increased customer's attention to the healthiness of their food choices, along with encouraging purchases of the most healthy items. In their report in the October issue of Preventive Medicine, Massachusetts General Hospital (MGH) investigators describe customer responses to surveys taken before and after the 2010 implementation of a system using green, yellow or red "traffic light" labels to reflect the nutritional quality of items.
Supermassive black holes: every large galaxy's got one. But here's a real conundrum: how did they grow so big?
A paper in today's issue of Science pits the front-running ideas about the growth of supermassive black holes against observational data — a limit on the strength of gravitational waves, obtained with CSIRO's Parkes radio telescope in eastern Australia.
