By 1941, the Russian dandelion, Taraxacum koksaghyz, supplied 30% of the USSR's rubber. During the Second World War, shortages of Havea rubber prompted other countries, including the United States, Britain and Germany, to begin cultivating dandelion rubber. Once the war was over and supplies returned to normal, these countries — including, ultimately, the Soviets — switched back to Hevea tree rubber because it was cheaper.
Giving at scale by the super-wealthy has done little to redistribute wealth from rich to poor, helping perpetuate social inequalities rather than remedying them, while paying considerable dividends to donors in the form of privilege and influence in society and politics, new research shows.
Corporal punishment in state schools in the UK was made illegal in 1986. This is the story about how it was eliminated in one Local Education Authority, Oxfordshire, before that.
My dad became CEO of Oxfordshire in 1978. He was young, and opposed corporal punishment, but knew, as he puts it, that “in a time of cuts, if I went to the politicians and asked them for money for canes they’d ask me how many I wanted, and did I want the luxury versions”. So he didn’t talk to them about corporal punishment.
“The toll of death is simply staggering — worse than I would have predicted,” said Arthur Caplan, founding head of the division of medical ethics at the New York University School of Medicine. “Covid has been nothing short of the worst failure of public policy in modern memory.”...
All other causes of death pale in comparison to the coronavirus death toll. So far, the coronavirus has killed roughly three times as many people as accidents, lung ailments, stroke or Alzheimer’s disease did in 2019. And the coronavirus has outpaced the number of deaths from diabetes, kidney disease, pneumonia and suicide by even larger multiples.
Prosecutors who want to hold police accountable should seek the bird in the hand, not the two in the bush. They should select charges in these cases so that conviction is a real possibility and, therefore, a real constraint on future police behavior. One "guilty" verdict on manslaughter will do more to reshape officers' behavioral calculus than an endless stream of "not guilty" decisions on murder.
Bottom line: Many people don’t like needles, and that could further slow vaccination efforts as winter turns to spring when supplies are expected to multiply and efforts to get the hesitant to sign up for a dose will intensify.
“Fear of needles was one of the barriers that was a significant predictor of people saying, ‘I don’t think I will get this vaccine,’” said Jeanine Guidry, an assistant professor at Virginia Commonwealth University who researches visual communication and conducted a survey of 500 people in July.
Mather had learned about inoculation more than a decade earlier, from an African man named Onesimus, whom he enslaved. When he asked if Onesimus had ever had smallpox, the man showed him a scar on his arm and explained that his community in Africa used infected material from one person to inoculate others against the disease. A few years later, Mather read a report from Turkey describing a similar procedure.
I remember last March, about three days into the shutdown when my Facebook newsfeed was filled with hilarious memes from parents who had been home teaching their children for a few days. The memes praised teachers, joked about suspending their own children, and immediately needing a vacation. As I saw these posts, I laughed along with them but thought to myself “this won’t last long”. And how right I was. People got amnesia and quick.
While all viruses find ways to evade the body’s defenses, a growing field of research suggests that the coronavirus unhinges the immune system more profoundly than previously realized.
A billionth of a century is approximately pi seconds. The diameter of the Earth is roughly half a billion inches. (Incidentally, one millionth of a century is about 52 and a half minutes. This microcentury is apparently the optimal time for a lecture: long enough to get into depth and detail; not so long that people fall asleep.)
In our view, as education researchers who specialize in science education, the learning sciences and educational assessment, we see an abundance of reasons to let states off the hook for testing this year....
Unfortunately, national experts and research findings indicate that high-stakes testing does not live up to its promise. Instead, research has shown serious negative side effects.
