This image of Hurricane Gonzalo was taken from the International Space Station by European Space Agency astronaut Alexander Gerst on October 16, 2014. In addition to the crew Earth observations from the space station, NASA and NOAA satellites provided continuous coverage of Hurricane Gonzalo as it moved toward Bermuda.
A cutting-edge paper has provided the first potential indication of direct detection of Dark Matter — something that has been a mystery in physics for over 30 years. Space scientists at the University of Leicester have detected a curious signal in the X-ray sky — one that provides a tantalizing insight into the nature of mysterious Dark Matter.
In May 2014, two new studies concluded that a section of the land-based West Antarctic ice sheet had reached a point of inevitable collapse. Meanwhile, fresh observations from September 2014 showed sea ice around Antarctica had reached its greatest extent since the late 1970s. To better understand such dynamic and dramatic differences in the region's land and sea ice, researchers are travelling south to Antarctica.
The Milky Way glitters brightly over the Atacama Large Millimeter/Submillimeter Array’s (ALMA) antennas, in this image taken by the ESO Ultra High Definition Expedition team as they capture the site in 4K quality. Currently under construction in the thin, dry air of northern Chile's Atacama desert at an altitude of 5,000 meters above sea level, ALMA will initially be composed of 66 high-precision antennas
Raytheon Company has unveiled its wearable computing Intel-Ops solution at the AUSA 2014 Meeting and Exposition. The new technology merges a proven, wearable computer system with situational awareness capabilities to create an enhanced real-time view of the battlefield for commanders and their troops.
The cold waters of Earth’s deep ocean have not warmed measurably since 2005, according to a new NASA study, leaving unsolved the mystery of why global warming appears to have slowed in recent years. Scientists at NASA's Jet Propulsion Laboratory in Pasadena, CA, analyzed satellite and direct ocean temperature data from 2005 to 2013 and found the ocean abyss below 1.24 miles (1,995 meters) has not warmed measurably.
Researchers are demonstrating revolutionary robotic techniques inspired by plants, featuring a 3-D-printed ‘trunk,’ ‘leaves’ that sense the environment and ‘roots’ that grow and change direction. Humans naturally understand problems and solutions from an animal’s perspective, tending to see plants as passive organisms that don’t ‘do’ much of anything, but plants do move, and they sense, and they do so in extremely efficient ways.
NASA has formally delivered to Alaskan officials a new technology that could help pilots flying over the vast wilderness expanses of the northern-most state. The technology is designed to help pilots make better flight decisions, especially when disconnected from the Internet, telephone, flight services and other data sources normally used by pilots.
UN-SCAN-IT Gel 7.1 gel analysis software converts virtually any scanner, digital camera or other image input device into an accurate high‑speed densitometer and digitizer system. Features include a zoomable and scalable analysis screen, lane analysis, segment analysis, dot blot analysis, color and grayscale gel analysis, clone drawing mode, MW calculation and calibration curves.
The National Oceanic and Atmospheric Administration (NOAA) and NASA are funding three demonstration projects that will lay the foundation for the first national network to monitor marine biodiversity at scales ranging from microbes to whales. The U.S. Department of the Interior's Bureau of Ocean Energy Management (BOEM) also plans to contribute.
Researchers have designed a new imaging system capable of obtaining up to 12 times more color information than the human eye and conventional cameras, which implies a total of 36 color channels. This important development will facilitate the easy capture of multispectral images in real time, and in the not too distant future it could also be used to develop new assisted vehicle driving systems, or to obtain more accurate medical images.
Scientists have created a new map of the world's seafloor, offering a more vivid picture of the structures that make up the deepest, least-explored parts of the ocean. The feat was accomplished by accessing two untapped streams of satellite data. Thousands of previously uncharted mountains rising from the seafloor, called seamounts, have emerged through the map, along with new clues about the formation of the continents.
India celebrated putting a spacecraft into orbit around Mars on September 24, 2014, hoping the rare feat will show the world it is open for business in space exploration and inspire a new generation of homegrown scientists to help drive growth. Those motivations help explain why India, a poor country of 1.2 billion, even invests in a space program when so many of its people lack access to proper toilets, electricity and health care.
Researchers have equipped a robot with a novel tactile sensor that lets it grasp a USB cable draped freely over a hook and insert it into a USB port. The sensor is an adaptation of a technology called GelSight, which was developed at MIT. The new sensor isn’t as sensitive as the original GelSight sensor, which could resolve details on the micrometer scale. But it’s smaller, and its processing algorithm is faster.
When natural disasters or human-made catastrophes topple buildings, search and rescue teams immediately set out to find victims trapped beneath the wreckage. During these missions, time is imperative, and the ability to quickly detect living victims greatly increases the chances of rescue and survival.
NTU is working with other international universities to build a global network of ‘citizen scientists’ on a free-to-access database for oceanographic data. To gain a better understanding of marine microbes that support the nutrient cycle and form the foundation of the food web, NTU scientists have embarked on a pilot project to crowd-source the collection of oceanographic data globally.
In our vain struggle to kill flies, hands and swatters often come up lacking. This is due to no fault of our own, but rather to flies’ compound eyes. Arranged in a hexagonal, convex pattern, compound eyes consist of hundreds of optical units called ommatidia, which together bestow upon flies a nearly 360-degree field of vision. With this capability in mind, researchers are drawing on this structure to create miniature light-emitting devices
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.
The University of Waterloo has unveiled a new satellite image of Antarctica, and the imagery will help scientists all over the world gain new insight into the effects of climate change. The mosaic is free and fully accessible to the academic world and the public. Using Synthetic Aperture Radar with multiple polarization modes aboard the RADARSAT-2 satellite, the CSA collected more than 3,150 images of the continent.
Researchers in Bangladesh have designed a computer program that can accurately recognize users’ emotional states as much as 87 percent of the time, depending on the emotion. Writing in the journal Behaviour & Information Technology, A.F.M. Nazmul Haque Nahin and his colleagues describe how their study combined — for the first time — two established ways of detecting user emotions: keystroke dynamics and text-pattern analysis.
As a report from the Obama administration warns that one in four bridges in the United States needs significant repair or cannot handle automobile traffic, Tufts University engineers are employing wireless sensors and flying robots that could have the potential to help authorities monitor the condition of bridges in real time.
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.
