Astronauts encountered minor toxic ammonia leak and glove damage in spacewalk job

On Friday, two of the National Aeronautics and Space Administration astronauts ventured outside the International Space Station for a spacewalk to perform a plumbing work have encountered a minor glove damage and leaking ammonia. However, NASA has confirmed that it was a very minor incident and it wasn’t a dangerous situation at all. Two NASA astronauts have been assigned to restore a ...

Study: Jellyfish and eels don’t push water to move forward

University of South Florida’s research team has revealed that jellyfish doesn’t move forward in water by creating a wave-like body motion to push against the water, instead it sucks the water toward them. Dr. Brad Gemmell, assistant professor in the Department of Integrative Biology, University of South Florida, along with a team of scientists from five institutions, studied the movement of these ...

Mass increase of Antarctic ice sheet greater than losses, finds NASA

A new study by NASA has found that Antarctica has started gaining ice sheets as it was accumulating about 10,000 years ago. Scientists say that the new data offer previously unrecorded gains in Antarctica, and challenges the reports of the 2013 Intergovernmental Panel on Climate Change (IPCC) that Antarctica is losing ice. According to the study published in the Journal of ...

World’s fastest silicon phototransistor could speed up digital cameras

Researchers and engineers at the University of Wisconsin-Madison (UW) have created the world’s most responsive and fastest flexible silicon transistor. For the first time, engineers have created a flexible silicon phototransistor that can sense high-sensitivity photodetection and stable performance under bending conditions. The highlight of the newly developed transistor is its size, which can be used to improve products like digital ...
