InSight lander takes its first selfie on Mars: NASA

December 12, 2018 3:05 pm

Washington: NASA’s InSight spacecraft has used a camera on its robotic arm to take its first selfie — a mosaic made up of 11 images, the US space agency said. This is the same imaging process used by Curiosity rover mission, in which many overlapping pictures are taken and later stitched together, NASA said in a statement. Visible in the selfie are the lander’s solar panel […]

Evidence of water discovered on asteroid Bennu: NASA

December 11, 2018 2:05 pm

Washington: Scientists have discovered evidence of water on asteroid Bennu, using data from NASA’s OSIRIS-REx spacecraft which recently reached the rocky cosmic body to unravel its mysteries. From August through early December this year, the spacecraft aimed three of its science instruments toward Bennu and began making the mission’s first observations of the asteroid. During […]

Long-lasting re-writable paper developed

Long-lasting re-writable paper developed

December 8, 2018 4:12 pm

Beijing : Scientists have developed an easy-to-make “rewritable” paper that can be drawn or printed on over and over again. Printed materials often get used once and are then discarded, creating waste and potential pollution. Researchers including those from the Fujian Normal University in China wanted to develop a simple method for making long-lasting re-writable paper that can be wiped clean […]

Rice plants may help clean wastewater from farms

Rice plants may help clean wastewater from farms

December 8, 2018 4:02 pm

Washington : Rice plants can be used to clean water draining from farms — which contain pesticides — before it gets into rivers, lakes, and streams, scientists suggest. Researchers wanted to stop pesticides from getting into water outside the farm in a way that was easy and cost-efficient for farmers. “We wanted something that was common, that could be applied […]

Four new gravitational waves detected

Four new gravitational waves detected

December 4, 2018 12:33 pm

Washington: Scientists have made four new detections of gravitational waves — ripples in the fabric of space and time — emanating from separate black hole mergers. So far the US-based LIGO and Europe-based VIRGO gravitational-wave detectors have recorded gravitational waves from a total of 10 black hole mergers and one merger of neutron stars. The […]

Black hole 'donuts' are actually gas fountains: Study

Black hole ‘donuts’ are actually gas fountains: Study

December 3, 2018 2:47 pm

Tokyo: Rings of gas surrounding supermassive black holes are not simple donut shapes, but dynamic fountains of gaseous matter, according to a study that may prompt re-writing of astronomy textbooks. Based on computer simulations and new observations from the Atacama Large Millimetre/submillimetre Array (ALMA) in Chile, researchers have concluded that the gas expelled from the centre interacts […]

Novel device can capture drinking water from air

Novel device can capture drinking water from air

December 3, 2018 12:51 pm

Dubai: Scientists have developed a simple device that can capture water from thin air, and release it when warmed by sunlight. The advance could provide a secure new source of drinking water in remote arid regions, researchers said. Globally, Earth’s air contains almost 13 trillion tonnes of water, a vast renewable reservoir of clean drinking water. Trials of many materials […]

Brain zapping may alleviate depression symptoms

Brain zapping may alleviate depression symptoms

December 2, 2018 2:55 pm

Washington: Scientists, including one of Indian origin, have identified a brain region that can be electrically stimulated to improve mood in people suffering from depression. According to a study published in the journal Current Biology, stimulation of a brain region called the lateral orbitofrontal cortex (OFC) reliably produced acute improvement in mood in patients who […]

NASA’s Martian quake sensor InSight lands at slight angle

December 1, 2018 9:45 am

Los Angeles: NASA’s unmanned Martian quake sensor, InSight, has landed at a slight angle on the Red Planet, and experts are hopeful the spacecraft will work as planned, the US space agency said Friday. The USD 993 million lander arrived Monday at its target, a lava plain named Elysium Planitia, for a two-year mission aimed […]
