Britain in Huawei Dilemma as China Relations Sour 

All, Business, News, Technology
There is growing speculation that Britain may be about to reverse course and ban Chinese firm Huawei from Britain’s rollout of 5G mobile telecoms technology.  Prime Minister Boris Johnson approved Huawei’s involvement in the construction of non-core elements of Britain’s 5G mobile network in January. The United States strongly criticized that decision, warning that the company is closely linked to the Chinese government and poses a big security risk. It appears Johnson may be about to heed that warning. “I am very, very determined to get broadband into every part of this country, reaching out for across the whole of the U.K. And we're convinced that we can do that,” Johnson told reporters Monday. “I am also determined that the U.K. should not be in any way be vulnerable to high-risk state vendors.

Researchers Say Climate Change Causing Arctic Spider Population Boom

All, News
A new study suggests earlier Arctic springs driven by climate change are providing wolf spiders in the region the opportunity to have more babies. The study, published in the June 24 edition of the biological sciences journal Proceedings of the Royal Society B, found that Arctic wolf spiders are taking advantage of the early spring season by producing more batches of offspring — called clutches — because warmer temperatures extend the season when the spiders are active. Authors of the study, from the Arctic Research Center at Denmark’s Aarhus University, dissected individual egg sacs from the spiders and counted the number of eggs and partially developed juvenile spiders. They compared those egg contents with the size of the mothers and determined that the spiders were producing two separate clutches, something previously only…

After US Departure, WHO Looking at Germany    

All, News
In the wake of America's official departure from the World Health Organization, a former senior director at the U.N. health agency predicted that other countries, particularly Germany, would likely step in to fill any void left by the single-biggest financial contributor.   At a briefing on Wednesday morning, Dr. David Heymann, a former assistant WHO director-general and an American, said he was “very disappointed” at the U.S. decision to exit the agency.   He says the U.S. has been behind incredibly important activities at WHO, noting it was the U.S. and its Cold War enemy Russia that spearheaded the global initiative to eradicate smallpox.   Heymann said, however, that WHO would likely just get on with its work.   He says Germany has become an important partner in global health recently and other countries are stepping up as…

Facebook Civil Rights Audit: ‘Serious Setbacks’ Mar Progress

All, Business, News, Technology
A two-year audit of Facebook’s civil rights record found "serious setbacks" that have marred the social network’s progress on matters such as hate speech, misinformation and bias.   Facebook hired the audit’s leader, former American Civil Liberties Union executive Laura Murphy, in May 2018 to assess its performance on vital social issues. Its 100-page report released Wednesday outlines a "seesaw of progress and setbacks" at the company on everything from bias in Facebook's algorithms to its content moderation, advertising practices and treatment of voter suppression.   The audit recommends that Facebook build a "civil rights infrastructure" into every aspect of the company, as well as a "stronger interpretation" of existing voter suppression policies and more concrete action on algorithmic bias. Those suggestions are not binding, and there is no formal…

Fossils Reveal Dinosaur Forerunner Smaller Than a Cellphone

All, News
Meet Kongonaphon kely, a pocket-sized dinosaur forerunner that was smaller than your cellphone.  The creature, which predated dinosaurs and flying pterosaurs, was just shy of 4 inches (10 centimeters) tall, according to a study published Monday in the journal Proceedings of the National Academy of Sciences. "Some of these things would have been quite cute animals," said study lead author Christian Kammerer, a paleontology researcher at the North Carolina Museum of Natural Sciences. Looking like a small dinosaur that could fit in your hand, Kammerer mused that it "would probably make a great pet."  Of course, no humans were around when Kongonaphon was roaming the wild, jumping around with its strong hind legs and feeding on bugs with its peg-like teeth, Kammerer said. The name means tiny bug slayer. The fossils, dug up in Madagascar, date from 237…

Czech Volunteers Develop Functioning Lung Ventilator іn Days

Tomas Kapler knew nothing about ventilators — he's an online business consultant, not an engineer or a medical technician. But when he saw that shortages of the vital machines had imperiled critically ill COVID-19 patients in northern Italy, he was moved to action."It was a disturbing feeling for me that because of a lack of equipment the doctors had to decide whether a person gets a chance to live," Kapler said. "That seemed so horrific to me that it was an impulse to do something."And so he did. "I just said to myself: 'Can we simply make the ventilators?'" he said.  Working around the clock, he brought together a team of 30 Czechs to develop a fully functional ventilator — Corovent.

The British government is set to end the participation of Chinese telecom giant Huawei in the building of Britain’s 5G phone network — a policy about-turn that will further deteriorate London’s strained relations with Beijing, but will please Washington, according to British media reports. The major policy change follows a fresh reassessment by Britain’s National Cyber Security Center, or NCSC, on the eavesdropping risks posed by the Chinese company, according to Britain’s Sunday Telegraph newspaper. British officials have confirmed to VOA the newspaper report is accurate. Previously the NCSC, a department within Britain’s intelligence agency GCHQ, said the security risks posed by Huawei could be safely managed and mitigated, a view not shared by U.S. intelligence agencies.
