Anthony Cheung’s formal mathematical training essentially ended with high school calculus. But as a musician and composer, he has explored mathematical phenomena in new ways, especially through their influence on harmony and timbre. “Through technology and thinking about acoustics, we can change sounds on the computer in innumerable ways,” says Cheung, whose musical composition earned him a 2012 Rome Prize from the American Academy in Rome.

It's easy to go online and get a 360-degree, ground-level view of almost any street in the US and throughout the world. Soon, scientists hope to do the same with coral reefs and other underwater wonders. They are learning to use specialized fisheye lenses underwater in the Florida Keys in hopes of applying "street view" mapping to research and management plans in marine sanctuaries nationwide. Some of the images will be available online...
In early August 2014, not one but two hurricanes were headed for the Hawaiian Islands. Storms arriving from the east are a relative rarity, and landfalling storms are also pretty infrequent. This image is a composite of three satellite passes over the tropical Pacific Ocean in the early afternoon.
North American lions, cheetahs and short-faced bears: Those are just a few fearsome critters from 25,000 years ago paleontologists already might have found in their first excavation of a bizarre northern Wyoming cave in 30 years. Good fossils also come in small packages: Exquisite rodent bones best examined by microscope, or even snippets of genetic material from long-extinct species, could be in their haul.
During the world's largest international maritime exercise, Sailors demonstrated a new system that could transform the future of electronic warfare and defense of ships at sea. Sponsored by the Office of Naval Research, Electronic Warfare Battle Management for Surface Defense will help Sailors and Marines coordinate electronic countermeasure responses to inbound threats faster than is possible through traditional voice communications
As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water which is predicted to extend across the whole Arctic Ocean before the middle of this century. Storms thus have the potential to create Arctic swell – huge waves that...
The federal government is planning to use sound blasting to conduct research on the ocean floor along most of the East Coast, using technology similar to that which spawned a court battle between environmentalists and researchers in New Jersey this summer. The U.S. Geological Survey plans this summer and next to map the outer limits of the continental shelf, and also study underwater landslides that would help predict tsunamis.
Fifteen years ago, NASA's Chandra X-ray Observatory was launched into space aboard the Space Shuttle Columbia. Since its deployment, Chandra has helped revolutionize our understanding of the universe through its unrivaled X-ray vision. Chandra, one of NASA's current "Great Observatories," along with the Hubble Space Telescope and Spitzer Space Telescope, is specially designed to detect X-ray emission from hot and energetic regions.
Thanks to NASA's Kepler and Spitzer Space Telescopes, scientists have made the most precise measurement ever of the radius of a planet outside our solar system. The size of the exoplanet, dubbed Kepler-93b, is now known to an uncertainty of just 74 miles (119 kilometers) on either side of the planetary body.
Even within a phylum so full of mean little creatures, the yellow-colored Ormia ochracea fly is distinguished among other arthropods for its cruelty — at least to crickets. Native to the southeastern U.S. states and Central America, the fly is a most predatory sort of parasite. It swoops onto the back of a singing male cricket, deposits a smear of larvae, and leaves its wicked brood to invade, kill and consume the cricket from inside out.
It takes only a couple of minutes, twice a day, but 101-year-old Richard Hendrickson is fiercely proud that he has done the same thing for his country and community nearly every day since Herbert Hoover was in the White House in 1930. The retired chicken and dairy farmer has been recording daily readings of temperature and precipitation on eastern Long Island longer than any volunteer observer in the history of the National Weather Service.
The globe is on a hot streak, setting a heat record in June. That's after the world broke a record in May. The National Oceanic and Atmospheric Administration announced July 21, 2014, that last month's average global temperature was 61.2 degrees, which is 1.3 degrees higher than the 20th century average. It beat 2010's old record by one-twentieth of a degree.
Inspired by science fiction, three bowling ball-size free-flying Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) have been flying inside the International Space Station since 2006. These satellites provide a test bed for development and research, each having its own power, propulsion, computer, navigation equipment, and physical and electrical connections for hardware and sensors for various experiments.
Scientists from Queen Mary University of London have found a successful way of identifying bird sounds from large audio collections, which could be useful for expert and amateur bird-watchers alike. The analysis used recordings of individual birds and of dawn choruses to identify characteristics of bird sounds. It took advantage of large datasets of sound recordings provided by the British Library Sound Archive, and online sources.
Researchers from Northwestern University and the University of New Mexico report evidence for potentially oceans worth of water deep beneath the United States. Though not in the familiar liquid form — the ingredients for water are bound up in rock deep in the Earth’s mantle — the discovery may represent the planet’s largest water reservoir.
Ever since we started the Google self-driving car project, we’ve been working toward the goal of vehicles that can shoulder the entire burden of driving. Just imagine: You can take a trip downtown at lunchtime without a 20-minute buffer to find parking. Seniors can keep their freedom even if they can’t keep their car keys. And drunk and distracted driving? History.
Scientists have demonstrated the feasibility of flying via brain control — with astonishing accuracy. The pilot is wearing a white cap with myriad attached cables. His gaze is concentrated on the runway ahead of him. All of a sudden the control stick starts to move, as if by magic. The airplane banks and then approaches straight on towards the runway. The position of the plane is corrected time and again
Astrophysicists recently won the ‘solar science lottery’ as they were observing the skies just as one of the most energetic and rarest of solar eruptions took place. The international team, which included researchers from Trinity College Dublin, was able to record the rare event from multiple telescopes to build the most detailed picture yet of an ‘X-class solar flare.’
DataApex has announced the release of a control driver for Symbiosis Technology Components manufactured by Spark Holland BV. The Symbiosis is SPARK's unique solution for fast integrated online SPE‐LC‐MS automation (XLC‐MS). Clarity can now control more than 470 instruments in total.
The U-2 spy plane outlasted the Cold War, outlived its successor and proved crucial a half-century ago when two superpowers were on the brink of nuclear war. But defense cuts now threaten to knock the high-flying reconnaissance aircraft out of the sky. The Air Force wants to gradually retire the fleet of 32 "Dragon Lady" planes, which can soar to an altitude of 70,000 feet, collect intelligence on North Korea and Russia and rapidly send ...
Devices that tap directly into the nervous system can restore sensation, movement or cognitive function. These technologies, called brain-machine interfaces or BMIs, are on the rise, increasingly providing assistance to people who need it most. But what exactly does it take to build a BMI?
NOAA's GOES-East satellite captured this stunning view of the Americas on Earth Day, April 22, 2014 at 11:45 UTC/7:45 a.m. EDT. The data from GOES-East was made into an image by the NASA/NOAA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, MD.
Recently published research describes how archaeologists outfitted a customized drone with a heat-sensing camera to unearth what they believe are ceremonial pits and other features at the site of an ancient village in New Mexico. The discovery of the structures hidden beneath layers of sediment and sagebrush is being hailed as an important step that could help archaeologists shed light on mysteries long buried by eroding desert landscapes
A joint study by researchers at the University of California, San Diego and the University of Toronto has found that a computer system spots real or faked expressions of pain more accurately than people can. The research team found that humans could not discriminate real from faked expressions of pain better than random chance
On August 3, 2004, NASA’s Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft began a seven-year journey, spiraling through the inner solar system to Mercury. One year after launch, the spacecraft zipped around Earth, getting an orbit correction from Earth’s gravity and getting a chance to test its instruments by observing its home planet.
Using data from NASA's Van Allen Probes, researchers have tested and improved a model to help forecast what's happening in the radiation environment of near-Earth space -- a place seething with fast-moving particles and a space weather system that varies in response to incoming energy and particles...
