Mysterious split-second burst of radio waves 'discovered' from outer space

Mysterious split-second burst of radio waves 'discovered' from outer spaceWashington, July 12 - A split-second burst of radio waves has been discovered by scientists using the Arecibo radio telescope in Puerto Rico that provides important new evidence of mysterious pulses that appear to come from deep in outer space.

The finding by an international team of astronomers marks the first time that a so-called "fast radio burst" has been detected using an instrument other than the Parkes radio telescope in Australia.


'Homemade' telescope helps discover 7 hidden dwarf galaxies

'Homemade' telescope helps discover 7 hidden dwarf galaxiesWashington, July 11 : A new 'homemade' telescope has helped the scientists in finding seven unseen dwarf galaxies in space.

Astronomers from Yale University made a telescope by stitching together telephoto lenses, which came to their aid in discovering the celestial surprises that were previously overlooked because of their diffuse nature. The galaxies may yield important insights into dark matter and galaxy evolution, while possibly signaling the discovery of a new class of objects in space.


Scientist unravel brain's way of interpreting emotions

Scientist unravel brain's way of interpreting emotionsWashington, July 10 : Scientists have unraveled the process of human brain of interpreting emotions by turning feelings into codes.

Cornell University neuro-scientist Adam Anderson, the senior author of the study, discovered that fine-grained patterns of neural activity within the orbitofrontal cortex (OFC), an area of the brain associated with emotional processing, act as a neural code which captures an individual's subjective feeling.


Siblings learn from each other during playtime: Study

Washington, July 10 - A new study has revealed that uninterrupted playtime between siblings is key for learning, as young children learn a lot from their older siblings.

Through the study, researchers from Concordia University have confirmed that teaching occurs naturally and spontaneously, but that both older and younger siblings initiate learning activities and that, siblings acting as teachers use a variety of instructional techniques during these informal lessons.


First ever pic of 'photosynthesis in action' revealed

First ever pic of 'photosynthesis in action' revealedWashington, July 10 - A new study has shown the first snapshots of photosynthesis in action as it splits water into protons, electrons and oxygen, the process that maintains Earth's oxygen atmosphere.

Petra Fromme, lead author of the research said that this study is the first step towards their ultimate goal of unraveling the secrets of water splitting and obtaining molecular movies of biomolecules.


NASA discovers fast neutrons emitting from Sun's outer layer

NASA discovers fast neutrons emitting from Sun's outer layerWashington, July 10 - NASA's MESSENGER spacecraft has discovered part of the outer layer of the Sun that is sending out modestly energetic subatomic particles called fast neutrons, which flowed past Mercury into space.

The researchers said that such charged particles twirl and gyrate around the magnetic field lines created by the vast magnetic systems that surround the Sun and Earth. Neutrons, however, not being electrically charged, travel in straight lines from the flaring region and can carry information about flare processes unperturbed by the environment through which they move.


Working memory plays major role in academic achievement

Working memory plays major role in academic achievementWashington, July 9 : A new study has revealed that working memory plays an important role in reading and early academic achievement among children.

The study suggested that children with learning difficulties might benefit from teaching methods that prevent working memory overload.

The study sought to identify the cognitive skills underpinning learning success, so children were tested for IQ and so-called "executive functions", a set of cognitive processes that people use to control their thoughts and actions, including how they remember information, control their emotions and shift between thoughts.


Study suggests faint galaxies illuminated early universe

Study suggests faint galaxies illuminated early universeWashington, July 9 - A new study has found that the light from tiny galaxies more than 13 billion years ago played a larger role than previously thought in creating the conditions in the universe as we know it today.

According to a new study by researchers at the Georgia Institute of Technology and the San Diego Supercomputer Center (SDSC) at the University of California, ultraviolet light from stars in these faint dwarf galaxies helped strip interstellar hydrogen of electrons in a process called reionization.


NASA captures 'mid-level' solar flare

NASA captures 'mid-level' solar flareWashington, July 9 - NASA has captured mid-level solar flares at its Solar Dynamics Observatory.

According to NASA , the solar flares, which have been classified as an M6.5-class flare, caused short-lived impacts to high frequency radio communications on the sunlit side of Earth.

The agency said that the initial solar radio observations suggest a coronal mass ejection (CME) was likely associated with this even, but any transient would not likely have a trajectory directly at Earth, and that more analysis will be conducted as more data becomes available. (ANI)


Jupiter's Moon shaped same way as Earth's surface: Study

Jupiter's Moon shaped same way as Earth's surface: StudyWashington, July 9 - A new laboratory model suggested that the ridges and troughs shaped on the surface of Jupiter's icy moon Ganymede were formed the same way as Earth's tectonic process.

Physical analog models were created that could simulate geologic structures in laboratory settings so that the developmental sequence of various phenomena could be studied as they occur.

The research suggested that characteristic patterns of ridges and troughs, called grooved terrain on Ganymede, resulted from its surface being stretched.


NASA says purported 'UFO' on Mars mere 'hot pixel'

NASA says purported 'UFO' on Mars mere 'hot pixel'Washington, July 8 - NASA has recently stated that the bright light recorded by the Curiosity rover on Mars was just a 'hot pixel' and not a UFO .

Justin Maki, leader of the team that built and operates Curiosity's navigation camera, said that in the thousands of images that they have received from Curiosity, they have seen ones with bright spots nearly every week and it was the hot pixel that has been around since they started using the Right Navcam, the Huffington Post reported.

He further added that these could be caused by cosmic-ray hits or sunlight glinting from rock surfaces.


New Mars map provides insight into water modifying planet's surface

New Mars map provides insight into water modifying planet's surfaceWashington, July 8 - A new geological map of mars has revealed new insight into surface modified by water over much of planet's history.

The map has been produced by Scott C. Mest and David A. Crown of the Planetary Science Institute, which established that the water in this area would be in the canyon systems of Waikato Vallis in the north part of the map and Reull Vallis in the central part of the map and these canyons were believed to have formed when underground water was released from plains materials to the surface, causing the ground to collapse.


'World's biggest-ever flying bird' had 24-foot wide wingspan

'World's biggest-ever flying bird' had 24-foot wide wingspanWashington, July 8 - Scientists have identified the fossilized remains of an extinct giant that could be the world's biggest-ever flying bird with 20-24-foot wingspan and soaring ability that enabled the creature to stay aloft for long distances without flapping its wings.

The creature has surpassed size estimates based on wing bones from the previous record holder i. e. a long-extinct bird named Argentavis magnificens.

Author Dan Ksepka of the National Evolutionary Synthesis Center in Durham, North Carolina, said that the upper wing bone alone was longer than his arm.


New 'Duck-billed' dino tracksite found in Alaska

New 'Duck-billed' dino tracksite found in AlaskaWashington, July 7 : New tracksite filled with footprints of duck-billed dinosaurs', technically known as hadrosaurs, have been found by three paleontologists in Alaska's Denali National Park.

The discovery has demonstrated that they not only lived in multi-generational herds but thrived in the ancient high-latitude, polar ecosystem.


Scientists decode plants' genes linked with elevated CO2 levels

Scientists decode plants' genes linked with elevated CO2 levelsWashington, July 7 : The researchers have discovered a new genetic pathway, encoded with four genes, in plants that control the density of breathing pores in response to elevated CO2 levels.

Julian Schroeder, biology professor, said that for each carbon dioxide molecule that was incorporated into plants through photosynthesis, a plant loses about 200 hundred molecules of water through their stomata.
