PROVIDENCE, R.I. [Brown University] -- Recent orbital and rover missions to Mars have turned up ample evidence of clays and other hydrated minerals formed when rocks are altered by the presence of water. Most of that alteration is thought to have happened during the earliest part of Martian history, more than 3.7 billion years ago. But a new study shows that later alteration -- within the last 2 billion years or so -- may be more common than many scientists had thought.

As Typhoon Melor approached a landfall in the central Philippines, NASA's RapidScat instrument identified the strongest winds north of the center. As the storm was making landfall in the eastern Visayas and Bicol regions of the Philippines early on Dec. 14, 2015 NASA-NOAA's Suomi NPP satellite provided a visible image that showed the extend of the storm.
LSU paleoclimatologist Kristine DeLong contributed to an international research breakthrough that sheds new light on how the tilt of the Earth affects the world's heaviest rainbelt. DeLong analyzed data from the past 282,000 years that shows, for the first time, a connection between the Earth's tilt called obliquity that shifts every 41,000 years, and the movement of a low pressure band of clouds that is the Earth's largest source of heat and moisture -- the Intertropical Convergence Zone, or ITCZ.
GAINESVILLE, FL - In Florida, a major fresh-market cabbage producing state, cabbage production currently relies on bare ground and subirrigation systems. Because of the large volume of water these systems need for irrigation, finding alternative production methods is a pressing need. Researchers at the University of Florida recently determined that plasticulture systems using drip irrigation can be effective for cabbage production in the state.
Exeter academics led an international team of experts in analysing observations from the NASA/ESA Hubble Space Telescope and the NASA Spitzer Space Telescope. Their combined power gave a detailed study of the atmospheres of 10 hot-Jupiter exoplanets - the largest number ever collectively studied - in a bid to understand their atmospheres. Previously, scientists had been puzzled that they had not observed water on some of these planets - but the latest study, published in Nature on Monday December 14, has revealed that their view of the water was only obscured by haze and cloud.
Astronomers have used the NASA/ESA Hubble Space Telescope and the NASA Spitzer Space Telescope to study the atmospheres of ten hot, Jupiter-sized exoplanets in detail, the largest number of such planets ever studied. The team was able to discover why some of these worlds seem to have less water than expected -- a long-standing mystery. The results are published in Nature.
RALEIGH, NC - The authors of a new study say that bringing new types of cut flowers to market is good for consumers and the floral industry. Alicain Carlson and John Dole published a study in the October 2015 issue of HortTechnology that can help pineapple lilies gain favor with cut flower growers, and may spark interest among floral consumers.
MOUNT VERNON, WA - Ready-to-eat salad mixes have experienced a tremendous increase in popularity and sales over the last 20 years. A study in HortScience reports that supermarket sales of the produce increased from $197 million in 1993 to $2.7 billion in 2008 in the U.S. Looking for ways to meet consumer demand and extend the production season of popular baby-leaf salad greens in the Pacific Northwest, scientists in Washington evaluated salad cultivars for suitability as spring and fall crops.
"Glasses-less" 3-D displays now commercially available dispense with the need for cumbersome glasses, but existing 3-D stereoscopic content will not work in these new devices, which project several views of a scene simultaneously. To solve this problem, Disney Research and ETH Zurich have developed a system that can transform stereoscopic content into multiview content in real-time.
Most people can tell if you're angry based on the way you're acting. Professor Jeffrey Jenkins can tell if you're angry by the way you move a computer mouse.
The BYU information systems expert says people experiencing anger (and other negative emotions--frustration, confusion, sadness) become less precise in their mouse movements and move the cursor at different speeds.
Thanks to advances in modern technology, Jenkins and his colleagues can now gather and process enough data points from your cursor movement to measure those deviations and indicate your emotional state.
ANN ARBOR, Mich. -- Parents of teens may struggle letting go of the reins when it comes to their children's health checkups, a new national poll suggests.
Just 34 percent of parents say their teen discussed health concerns privately with a doctor without them in the room, and less than 10 percent say their teens can complete their health history form independently.
Today's report from the C.S. Mott Children's Hospital National Poll on Children's Health at the University of Michigan includes a nationally-representative group of parents of teens ages 13-18.
December 11, 2015--(BRONX, NY)--Feeling stressed out increases the likelihood that elderly people will develop mild cognitive impairment--often a prelude to full-blown Alzheimer's disease. In a new study, scientists at Albert Einstein College of Medicine and Montefiore Health System found that highly stressed participants were more than twice as likely to become impaired than those who were not.
NASA analyzed the rainfall rates occurring in Tropical Cyclone 05S, now renamed Tropical Cyclone Bohale.
NASA's Aqua satellite captured an image as Tropical Depression Melor formed in the Northwestern Pacific Ocean close to the island of Yap.
"Less or less severe storms in the mid-latitudes, this at first sight seems to be good news - but unfortunately it isn't," says lead-author Jascha Lehmann. "These storms have a moderating effect on land temperatures as they bring maritime air from the oceans to the continents and a lack of them can thus favor extreme temperatures."
