Washington, Nov. 18 - Researchers have created the first battery electrode that is capable of healing itself.
The development has opened a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell phones and other devices.
The team from Stanford University and the Department of Energy's (DOE) SLAC National Accelerator Laboratory, said that the secret of the breakthrough is a stretchy polymer that coats the electrode, binds it together and spontaneously heals tiny cracks that develop during battery operation.
Washington, Nov. 18 - Researchers have discovered some of the underlying physics that could help explain how insects could so quickly recover from a stall in midflight - unlike an aircraft, where a stalled state most often leads to a crash landing.
The analysis, in which the researchers studied the flow around a rotating model wing, improves the understanding of how insects fly and informs the design of small flying robots built for intelligence gathering, surveillance, search-and-rescue, and other purposes.
Washington, Nov. 18 - Researchers have developed an image analysis and segmentation algorithm specifically to aid planetary scientists with this very basic, but often difficult, task.
Instruments on the Curiosity Mars rover not only measure the chemistry of rocks, elemental abundances of soils and wind speeds, but also take an incredible number of images from both mast-mounted cameras and up-close imaging systems mounted to robotic arms.
The process of analyzing soil images can be daunting, particularly when there are thousands of images and when the particles can be on the order of only 5-10 pixels wide.
Washington, Nov 17 : A researcher has tried to explore leveraging penguins' "rocket" properties to create new propulsion technologies with high maneuverability and improved hydrodynamic efficiency.
Back in 1991, Nature published a picture from the IMAX movie Antarctica, along with the caption: "Emperor penguins may be waddling jokes on land, but underwater they can turn into regular rockets... accelerating from 0 to 7 m/s in less than a second."
Washington, Nov 17 - The US space agency NASA Saturday rolled out to the launching pad at Cap Canaveral, Florida, the Atlas 5 rocket, which will blast off Monday for Mars carrying the MAVEN spacecraft, which will study the atmosphere of that planet.
The rocket, 57.3 metres long, is scheduled to take off from Florida Monday at 1:28 p. m.
Meteorologists point to a 60 percent probability of favourable weather conditions for the rocket launch on that day and hour.
Washington, Nov. 16 - Researchers have said that the dominant, abundant corals that have wide distributions are much affected by global changes in climate and ocean chemistry mostly affect.
The team of scientists from the University of Hawaii - Manoa (UHM), Joint Institute for Marine and Atmospheric Research (JIMAR) and the National Oceanic and Atmospheric Administration (NOAA) evaluated both the geologic record of past extinctions and recent major events to assess the characteristics of dominant corals under various conditions.
Washington, Nov. 16 - Researchers have found two new species of beautiful soft coral species, named Gorgonians, in the waters of the Pacific.
The two new species belong to the gorgoniid genus Eugorgia, which is exclusively found in the eastern Pacific.
It has a wide geographic and bathymetric range of distribution, found from California to Peru and extends down to 65 m deep.
The genus Eugorgia is recognised for their vibrant colored colonies decorating the ocean bottom. The white color has been reported only for one species, Eugorgia alba, but this research adds two more pale representatives within the genus.
Washington, Nov. 16 - Scientists have combined data from Chandra X-ray Observatory, NASA's Spitzer Space Telescope, and ground-based facilities to build a 3D model of the 300-year old Cassiopeia A supernova that blew a massive star apart, and sent the debris flying at a velocity of millions of miles per hour.
To coincide with Cas A being featured in this new 3D effort, a specially-processed version of Chandra's data of this supernova remnant is also being released.
Washington, Nov. 16 - Two large, complex sunspots have been spotted by astrophysicists moving across the face of the sun.
One, which produced considerable solar activity in the past weeks, has almost rotated off completely.
A new sunspot rounded into view on Nov. 11, 2013 and is now making its way across the Earth-side of the sun.
An active region can contain one or more sunspots. The National Oceanic and Atmospheric Administration numbers active regions consecutively as they are observed on the sun.
Active region 1890 first appeared on Nov. 2, 2013, and is now almost out of view over the sun's right-hand horizon.
Washington, Nov 15 - The Hubble Space Telescope has clicked the best ever image of the globular cluster Messier 15, a gathering of very old stars that orbits the Milky Way's center.
This glittering cluster contains over 100,000 stars, and could also hide a rare type of black hole at its center.
This multi-colored firework display is a cluster of stars known as Messier 15, located some 35,000 light-years away in the constellation of Pegasus (The Winged Horse). It is one of the oldest globular clusters known, with an age of around 12 billion years.
Washington, Nov. 15 - Researchers are using new theoretical models to find if Earth-like conditions exist in some other planet.
Yann Alibert of the Center for Space and Habitability (CSH) at the University of Bern, said that the question whether so-called exoplanets are habitable or not is difficult to answer, as all the necessary conditions a planet has to fulfill in order to be habitable is not known.
Based on the mass and radius of a planet Yann Alibert was able to determine criteria that exclude the possibility of life as we know it.
Washington, Nov. 15 - NASA's Hubble Space Telescope has shown how Milky Way looked in it's formative years.
Astronomers used Hubble's deep-sky surveys to study the evolution of 400 galaxies similar to the Milky Way and noted their appearance at various stages of development over a time span of 11 billion years.
Judging from images of these far-flung galaxies, they found the Milky Way likely began as faint, blue, low-mass object containing lots of gas. Gas is the fuel for star birth and the blue color is an indicator of rapid star formation.
Washington, Nov. 13 : A new study has found well-preserved remnants of a complex ecosystem in a nearly 3.5 billion-year-old sedimentary rock sequence in Australia.
The Pilbara district of Western Australia constitutes one of the famous geological regions that allow insight into the early evolution of life.
Mound-like deposits created by ancient photosynthetic bacteria, called stromatolites, and microfossils of bacteria have been described by scientists in detail.
Washington, Nov. 13 - NASA has brought out a natural-color photograph of Saturn from space, the first of its kind, in which Saturn, its moons and rings, and Earth, Venus and Mars, all are visible.
The new panoramic mosaic of the majestic Saturn system taken by NASA's Cassini spacecraft, which shows the view as it would be seen by human eyes, was unveiled at the Newseum in Washington on Tuesday.
Washington, Nov. 12 - Researchers have been able to create robotic devices after observing snails and clams.
By studying and adapting the biological properties of the snail to robotic devices, team led by Anette Hosoi, professor of mechanical engineering at the Massachusetts Institute of Technology, has been able to create a " RoboSnail," which can climb walls and stick to overhead surfaces much like its living counterpart.
Such a device can have potential uses in invasive surgery and oil well drilling, among other applications.
