Jurassic marine reptile was warm-blooded, had blubber, used camouflage

Science
Dec. 5 (UPI) -- New research suggests Jurassic ichthyosaurs were more like modern marine mammals than previously realized. The ancient marine reptiles were ubiquitous in the Jurassic oceans. Studies of ichthyosaur fossils suggest they were dolphin-like in appearance, but until now, paleontologists knew relatively little about their biology and behavior. According to the new study, the reptiles were warm-blooded, had blubber and used coloration to camouflage themselves from predators. "Ichthyosaurs are interesting because they have many traits in common with dolphins, but are not at all closely related to those sea-dwelling mammals," Mary Schweitzer, professor of biological sciences at North Carolina State University, said in a news release. Previous research suggested ichthyosaurs gave l...

Facebook used to 'incite offline violence' in Myanmar, says report

Technology
Facebook has said it agrees with a report that found it had failed to prevent its platform being used to "incite offline violence" in Myanmar.The independent report, commissioned by Facebook, said the platform had created an "enabling environment" for the proliferation of human rights abuse.It comes after widespread violence against the Rohingya minority which the UN has said may amount to genocide. The report said Facebook would have to "get it right" before 2020 elections.Facebook has more than 18 million users in Myanmar. For many, the social media site is their main or only way of getting and sharing news.The network said it had made progress in tackling its problems in Myanmar but that there was "more to do". Last year, the ...

Chemicals used in Deepwater Horizon spill were ineffective, study says

Science
Nov. 1 (UPI) -- The chemical dispersants used to clean up oil after the Deepwater Horizon spill in the Gulf of Mexico in 2010 were ineffective and unneeded, a new study says. Researchers report in a study published this week that dispersants used in the largest oil spill in U.S. history -- 210 million gallons of oil poured into the Gulf over 87 days after a BP oil rig exploded -- played no role in its clean up. BP injected 3,000 tons of a subsea dispersant called Corexit to push back the spread of oil and dissolve its particles. Instead, the researchers report, the dispersant was rendered ineffective due to the depth of the oil. And according to the study, the Corexit may have suppressed the growth of oil degrading sea bacteria, in addition to making the oil itself more toxic. "The resul...

Chinese kit 'putting all of us at risk' if used in 5G

Technology
Security threats from Chinese companies building 5G networks could end up "putting all of us at risk" if they are not tackled quickly, according to a former security minister. Speaking to Sky News, Admiral Lord West, a former First Sea Lord who served under Gordon Brown as a security minister, urged the government to set up a unit reporting directly to the prime minister to monitor the risk posed by Chinese equipment in 5G.5G has been hailed as the next great leap for mobile communications, enabling everything from smart cities to hologram calls.However, the best 5G technology comes from Chinese companies, raising the fear that China's government could have ground-level access to - even control of - the UK's critical data infrastructure.

The Amazon is flooding five times more often than it used to

The Amazon is flooding five times more often than it used to

Science
Sept. 19 (UPI) -- The Amazon, the world's largest river, is flooding five times more frequently than it did 100 years ago. Scientists in England, Chile and Brazil analyzed river level records dating back more than a century. The data showed extreme floods -- when water levels rise at least 95 feet, triggering an emergency declaration in the city of Manaus -- occurred approximately once every 20 years during the first half of the 20th century. Today, extreme floods occur every four years. "Increases of severe droughts in the Amazon have received a lot of attention by researchers," Jonathan Barichivich, researcher at the Austral University of Chile, said in a news release. "However, what really stands out from this long-term river record is the increase in the frequency and severity of the ...
