Lead trapped in Arctic ice reveals economic impact of wars, plagues

Science
July 10 (UPI) -- Today, economists use a wide variety of sophisticated tools to measure economic output. But how does one measure economic activity that happened 1,000 years ago? One way is measure changes in lead pollution levels trapped in ancient ice. Using Arctic ice cores, an international team of researchers successfully retraced the economic ups and down of the last 1,500 years. The findings, published this week in the journal Proceedings of the National Academy of Sciences, revealed the the economic impacts of wars and plagues. "We all were surprised at how similarly lead pollution varied across this half of the Arctic and how closely those variations coincided with known historical events," Joe McConnell, director of DRI's Ultra-Trace Ice Core Chemistry Laboratory at the Desert ...

Badgers lead mammal roadkill list

Science
More than 900 badgers have been reported as roadkill so far this year. Almost twice as many of the nocturnal animals have been counted compared with foxes and hedgehogs, which are next on the 2019 mammal roadkill list.Pheasants top the list of bird fatalities to date, followed by woodpigeons and blackbirds.Project Splatter, which compiles the data, has received more than 5,500 reports from the pubic in the six months to June.Top three mammals (this year so far): Badger 905 Fox 475 Hedgehog 453 Top three birds (this year so far): Pheasant 1,347 Woodpigeon 156 Blackbird 93 Among some of the more unusual sightings this year are reports of a beaver found on the A9 in Scotland, and a wallaby near Oxford.The number of badgers and foxe...
Squeezing blood vessels may lead to Alzheimer’s cognitive decline

Squeezing blood vessels may lead to Alzheimer’s cognitive decline

Health
June 20 (UPI) -- Researchers may be closer to discovering a cause of cognitive decline brought on by Alzheimer's disease, a new study says. The constriction of cells surrounding blood vessels may cause decreased blood flow to the brain, which has already been linked to Alzheimer's disease, according to research published Thursday in the journal Science. "Since reduced blood flow is the first clinically detectable sign of Alzheimer's, our research generates new leads for possible treatments in the early phase of the disease," Ross Nortley, a researcher at University College London and study lead author, said in a news release. The researchers analyzed capillaries in human brain tissue affected by Alzheimer's and in mice engineered to grow a pathology for the disease. They applied a protei...

Vigil photos lead to WeChat lockout

Technology
China's WeChat is a site for social interaction, a form of currency, a dating app, a tool for sporting teams and deliverer of news: Twitter, Facebook, Googlemaps, Tinder and Apple Pay all rolled into one. But it is also an ever more powerful weapon of social control for the Chinese government.I've just been locked out of WeChat (or Weixin 微信 as it is known in Chinese) and, to get back on, have had to pass through some pretty Orwellian steps - steps which have led others to question why I went along with it.One reason is that life in Beijing would be extremely difficult without WeChat. The other is that I could not have written this piece without experiencing the stages which have now clearly put my image, and even my voice, on some sort of biometric datab

St. Louis Blues fend off Boston Bruins in Game 5, grab 3-2 series lead

Sports
June 6 (UPI) -- The St. Louis Blues are one win away from the franchise's first NHL championship after a 2-1 victory over the Boston Bruins in Game 5 of the Stanley Cup Final on Thursday night. Blues goalie Jordan Binnington had a superb performance in net, stopping 38 of the 39 shots he faced. St. Louis has secured back-to-back wins since suffering a 7-2 blowout loss at home in Game 3. "[Binnington] was excellent all game and did a great job in the first period," Blues head coach Craig Berube told reporters. "We were tested in the first, for sure, and Binners stood tall. Big reason we won the game. ... Our goalie was good and our team was gutsy." Blues forward Ryan O'Reilly notched the first goal of the night in the opening minute of the second period. Zach Sanford tossed a no-look, bet...
