“two studies published in November found that legalization has not been associated with increases in adolescent marijuana use or addiction. In fact, there is some evidence that both decline when pot prohibition is repealed for adults.”
“Earth saw a lot of commotion when its magnetic poles flipped 42,000 years ago.
Scientists have known about the flip since the late 1960s. Earth’s magnetic poles aren’t static – they’re generated by electric currents from the planet’s liquid outer core, which is constantly in motion. As of late, Earth’s magnetic North pole has wandered considerably on a path toward northern Russia.
But for the most part, scientists didn’t think the last pole flip had a major environmental impact. Sure, the planet’s magnetic field got weaker, allowing more cosmic rays to penetrate the atmosphere, but plant and animal life wasn’t known to have been greatly affected.
A new study now suggests a more dramatic phenomenon occurred: The additional cosmic rays may have depleted ozone concentrations, opening the floodgates for more ultraviolet radiation in the atmosphere. Shifting weather patterns may have expanded the ice sheet over North America and dried out Australia, prompting the extinction of many large mammal species. A solar storm, meanwhile, might have driven ancient humans to seek shelter in caves.
As competition for resources grew, our closest extinct human relative, Neanderthals, may have died out.”
…
“Not all researchers are convinced by Turney and Cooper’s analysis. Chris Stringer, an anthropologist at the Natural History Museum in London, told The Guardian that although the Laschamps excursion could have contributed to Neanderthals’ demise, it’s hard to know exactly when they died out.
“They did survive longer and ranged more widely than just Europe, and we have a very poor fix on the timing of their final disappearance across swathes of Asia,” Stringer said.
James Channell, a geologist at the University of Florida, told NPR that historical records of ice cores dating back 42,000 years don’t indicate a global climate crisis. Still, he added, “there does appear to be a linkage” between the extinction of large mammals and the weakening of Earth’s magnetic field.
At the very least, the new study offers a hint about what could happen if magnetic north and south flip again.”
“While there is still some debate around the potential increase in drunk driving, there is a vast, peer-reviewed, scientific literature around the harms of secondhand smoke inhalation, and around the massive health benefits associated with the sharp decline in smoking in part due to smoke-free policies.
We know that smoking bans have been effective at reducing secondhand smoke exposure. Bans in restaurants, bars, and other hospitality establishments have the added benefit of ensuring that workers are not forced to carry the health costs against their will simply due to their place of employment. Bans have also been effective at reducing smoking and “reducing opportunities to smoke, changing smoking norms, and reducing smoking rates.”
Smoking and exposure to secondhand smoke increases the risk of cardiovascular disease, pulmonary disease, cancer, and death. Research has shown that heart attack admissions “rapidly declined” after the implementation of 100 percent smoke-free laws.
All of this to say that if there was in fact a small increase in fatal drunk driving accidents as a result of these bans, the bans were still worth it.”

“it turns out that your brain on grievance looks a lot like your brain on drugs. In fact, brain imaging studies show that harboring a grievance (a perceived wrong or injustice, real or imagined) activates the same neural reward circuitry as narcotics.”
…
“in substance addiction, environmental cues such as being in a place where drugs are taken or meeting another person who takes drugs cause sharp surges of dopamine in crucial reward and habit regions of the brain, specifically, the nucleus accumbens and dorsal striatum. This triggers cravings in anticipation of experiencing pleasure and relief through intoxication. Recent studies show that similarly, cues such as experiencing or being reminded of a perceived wrong or injustice — a grievance — activate these same reward and habit regions of the brain, triggering cravings in anticipation of experiencing pleasure and relief through retaliation. To be clear, the retaliation doesn’t need to be physically violent—an unkind word, or tweet, can also be very gratifying.”
…
“similar to the way people become addicted to drugs or gambling, people may also become addicted to seeking retribution against their enemies—revenge addiction. This may help explain why some people just can’t let go of their grievances long after others feel they should have moved on—and why some people resort to violence.”
…
“Trump’s unrelenting efforts to retaliate against those he believes have treated him unjustly (including, now, American voters) appear to be compulsive and uncontrollable. The harm this causes to himself and others is obvious but seems to have no deterrent effect. Reports suggest he has been doing this for much of his life. He seems powerless to stop. He also seems to derive a great deal of pleasure from it.”
…
“Like substance addiction, revenge addiction appears to spread from person to person. For instance, inner-city gun violence spreads in neighborhoods like a social contagion, with one person’s grievances infecting others with a desire to seek vengeance. Because of his unique position and use of the media and social networks, Trump is able to spread his grievances to thousands or millions of others through Twitter, TV and rallies. His demand for retribution becomes their demand, causing his supporters to crave retaliation—and, in a vicious cycle, this in turn causes Trump’s targets and their supporters to feel aggrieved and want to retaliate, too.”
…
“Political parties and interest groups have come to rely upon inflaming grievances and stoking vindictiveness to generate donations and motivate voters. Media, entertainment and social networking giants also rely upon grievance and revenge-based content to attract viewers and users and increase advertising and sales. More people need to become savvy about how, why and for whose benefit they are being made to feel aggrieved and must decide to stop dealing in the drug of their own destruction.”
“The scientists who do this kind of research argue that we can better anticipate deadly diseases by making diseases deadlier in the lab. But many people at the time and since have become increasingly convinced that the potential research benefits — which look limited — just don’t outweigh the risks of kicking off the next deadly pandemic ourselves.”
“On Monday afternoon, President Trump told the press that he’s taking a drug called hydroxychloroquine as a preventative to ward off the coronavirus — a practice for which there is no evidence and that could, in theory, have negative side effects as serious as hallucinations and heart failure.
“I take it,” Trump said. “So far, I seem to be okay.”
Hydroxychloroquine is an anti-malarial drug that a non-randomized study from a French lab, publicized in March, initially suggested could be used as a treatment in fighting the coronavirus. In March, Trump frequently touted the drug, calling it “one of the biggest game changers in the history of medicine.” But further studies have concluded that it is not effective in many cases and should not be routinely used to treat patients.
Trump seems to be taking it not as a treatment for Covid-19 — he’s apparently tested negative — but as a preventive measure to protect himself from contracting it. There’s no medical evidence supporting the idea that this would work, and the risk of potential psychiatric and cardiac side effects, which are serious, would likely strongly outweigh any (hypothetical) benefits.
Nevertheless, Trump claims to be taking the drug anyway.”
…
“On the one hand, if Trump — a notorious liar — is telling the truth about taking the drug, it’s certainly newsworthy that the president is taking a dangerous medication for no good reason. It would not only speak to his judgment and fitness for office but also suggest a risk to his health and mental competence.
On the other hand, Trump may be trying to goad the media into getting bogged down in an issue that’s less important than the actual outbreak and Trump’s failed response to it. At the press conference, he told reporters, “I was just waiting for your eyes to light up when I said this, when I announced this,” indicating he’s perfectly aware that he’s starting a controversy.”
