Submission + - Ocean Cleanup concludes Mega Expedition of Great Pacific Garbage Patch->

hypnosec writes: The reconnaissance mission of the Great Pacific Garbage Patch dubbed the Mega Expedition by Ocean Clean has been concluded and the large-scale cleanup of the area is set to begin in 2020. The primary goal of the Mega Expedition was to accurately determine how much plastic is floating in the Great Pacific Garbage Patch. This was the first time large pieces of plastic, such as ghost nets and Japanese tsunami debris, have been quantified.

Submission + - DNA can efficiently store data for thousands of years->

hypnosec writes: Researchers have managed to store data onto DNA with higher efficiency and successfully read it off without errors. Researchers including Robert Grass, Ph.D., of ETH Zurich, successfully encoded 83 kilobytes of text from the Swiss Federal Charter from 1291 and the Method of Archimedes from the 10th century onto DNA. The team then encapsulated the DNA in silica spheres and warmed it to nearly 160 degrees Fahrenheit for one week, which is the equivalent of keeping it for 2,000 years at about 50 degrees. When they decoded it, it was error-free.

Submission + - Wikipedia might not be a reliable place for information on global warming->

hypnosec writes: Wikipedia might not be the most reliable online resource for information on certain politically sensitive topics, a new study has revealed. According to a paper published in the journal PLOS ONE, Wikipedia entries on politically controversial scientific topics including acid rain, global warming, climate change can be unreliable due to information sabotage. According to researchers, Wikipedia entries on such topics receive near-daily edits, many of which make the information rather distorted. Dr. Gene E. Likens, co-author of the study and President Emeritus of the Cary Institute of Ecosystem Studies and a Distinguished Research Professor at the University of Connecticut, Storrs suggested that though acid rain is not a controversial topic, “Wikipedia’s acid rain entry receives near-daily edits, some of which result in egregious errors and a distortion of consensus science.”

Submission + - Toyota recalls 625,000 hybrid vehicles over software glitch->

hypnosec writes: Japanese car manufacturer Toyota on Wednesday recalled 625,000 hybrid vehicles globally to fix a software defect. The automaker said that the defect in question might lead to shut down of the hybrid system while the car is being driven. The recall was due to software settings that could result in “higher thermal stress” in parts of a power converter, potentially causing it to become damaged. Toyota dealers will update the software for both the motor/generator control ECU and hybrid control ECU in the involved vehicles.

Submission + - Gobbling up space debris the Pac-Man way->

hypnosec writes: Switzerland's orbital cleaning satellite project dubbed CleanSpace One is inching ahead towards completion as engineers from eSpace, École polytechnique fédérale de Lausanne (EPFL)’s Center for Space Engineering and Signal Processing 5 Laboratory (LTS 5), and partners from HES-SO are currently testing a camera system, visual approach algorithms and a “Pac-Man” style capture system. The prototype resembles a net in the form of a cone that unfolds and then closes back down once it has captured the small satellite. With a plan to launch in 2018, CleanSpace One's approach and capture systems has passed the prototype stage. The next stage will combine putting together the first version of the engineering models – which will be more accurate than the prototypes – and more extensive tests.

hypnosec writes: In a first of its kind initiative, Thom Feeney, a shoe shop worker from Yorkshire in the UK has started a crowdfunding campaign on IndieGoGo to bailout Greece with a goal of €1.6 billion. The reason Feeney started this campaign was that he got bored of the daily dithering over Greece with various European countries deliberating whether they can help the Greek people or not. "Why don't we the people just sort it instead?" Feeney writes in the crowdfunding campaign description.

Submission + - Corals may survive global warming thanks to "genetic rescue"-> 1

hypnosec writes: Researchers have found that some coral populations already posses genetic variants that could help them tolerate the increasing ocean temperatures and if such corals are mixed and matched with corals from different latitudes they can be made to survive global warming through 'genetic rescue'. Researchers exposed the corals' larvae to increasingly warm temperatures for long periods of time, and then analyzed the genes of the surviving individuals. Their results reveal that the more heat-tolerant corals produced larvae that were 10 times more likely to survive heat exposure than the larvae of the less heat-tolerant corals.
