Regrettably, the jet pack would never truly take off: Rocket belts were too expensive, not fuel efficient, and had an extremely short flight duration. The military stopped funding the project, and the rocket belt became a novelty.

Briefly, the researchers found a vas deferens between men treated with phosphodiesterase five inhibitors, like Viagra, and those treated with alprostadil.

Public health experts and the CDC agree that if you are vaccinated and in the company of people who aren’t — or if you don’t know their status — you should continue the safeguards of masking and maintaining your distance.

Putting all these developments together, "it is not unreasonable that we might have the capacity to develop a human embryo from fertilization to birth entirely outside the uterus," Paul Tesar, a developmental biologist at Case Western Reserve University School of Medicine, told the Times. "Whether that is appropriate is a question for ethicists, regulators, and society."

Now, real Going Medieval heads know of course that there is no such thing as a chivalric code, and that chivalry in general has absolutely nothing to do with the treatment of women. Luckily, I have already written that for you, so I don’t need to do it again. What I do want to talk about is that while the idea of chivalry and knights on horses coming to the rescue of damsels in distress is made up, actually the comparison of knights to police is not actually so far off.

That is not, however, a good thing.

One possible piece of evidence for prehistoric mathematics is the Ishango bone. It was dug up by a Belgian geologist in the 1950s in Ishango, in what is today the Democratic Republic of the Congo (near the border with Uganda); the bone had been buried in a volcanic eruption some 20,000 years ago.

Residents of US nursing homes with more than 40% non-white residents died of COVID-19 at 3.3 times the rate of those of those with higher proportions of white residents, a study today in JAMA Network Open shows.

No one talked about it much, but public health professionals were all aware of a potential nightmare scenario when COVID vaccinations started up in bulk. No, not a slew of severe adverse events – the clinical trials made it clear that these were fairly safe interventions. The nightmare scenario – discussed in small groups online and on campus, was this: What if the vaccines reduce the severity of COVID-19, but not the transmissibility?  In other words, what if the vaccine takes someone who would have been sick with COVID-19, isolating, at home, and converts them into an asymptomatic carrier – out in the world, spreading virus like millions of Typhoid Mary’s.

Fortunately, it doesn’t look like this scenario will come to pass.

As the pandemic sends thousands of recovering alcoholics into relapse, hospitals across the country have reported dramatic increases in alcohol-related admissions for critical diseases like alcoholic hepatitis and liver failure.

Alcoholism-related liver disease was a growing problem even before the pandemic, with 15 million people diagnosed with the condition around the country, and with hospitalizations doubling over the past decade.

It is often said that one theory can be driven out only by another; the neoclassicals have a complete theory (though I maintain it is nothing but a circular argument) and we need a better theory to supplant them. I do not agree. I think any other ‘complete theory’ would be only another box of tricks. What we need is a different habit of mind — to eschew fudging, to respect facts and to admit ignorance of what we do not know.

KHN sent queries about reinfection surveillance to all 50 states and the District of Columbia. Of 24 responses, fewer than half provided details about suspected or confirmed reinfection cases. Where officials said they’re actively monitoring for reinfection, they have found far more potential cases than previously anticipated.

There were thousands of Tweets which said exactly what I was going to say. I thought of ‘liking’ them, to show solidarity, but in the end, I thought ‘he’s just a prat who likes the attention, and my kids need a hug’, so I put my phone down

Covid-19’s fierce winter resurgence in California is notable not only for the explosion in overall cases and deaths in the state’s sprawling urban centers. This latest surge spilled across a far greater geographic footprint, scarring remote corners of the state that went largely unscathed for much of 2020.

A line of discussion began in the group after Linda L. posted a screenshot of some caribou crossing the road in Finland - In all these miles of driving and recording by the Street View car, had it ever hit anything? Street View Roadkill? In theory you'd be able to see the entire story: a poor creature running into the road in front of the car and then left on the road out the other side. I had never seen anything, had others?

I had a friend once who claimed it was his special ability to be able to tell exactly when it would start raining. Like he’d look up at the sky and say “in 90 minutes, it will be raining”.  This is not the most useful of talents in the age of meteorology but nevertheless I thought of him as I read this study, appearing in JAMA Internal Medicine, which found that ED visits for respiratory complaints spiked before a thunderstorm.

“Every day, in every way, I am getting better and better.”

Pearson, the world’s learning company, today released the results of its second Global Learner Survey, an annual study capturing the voice of learners worldwide. The findings show learners believe there is little likelihood of ever returning to the pre-COVID world of fully in-person work and learning, with more than 75% saying the pandemic has fundamentally changed education as we know it. While learners come to terms with this new reality, they also are pushing for schools and government to address inequity and rushing to gather the digital skills that will help them adapt to the new economy.

Theirtube is a YouTube filter bubble simulator that provides a look into how videos are recommended on other people’s YouTube. Users can experience how the YouTube home page would look for six different personas. Each persona simulates the viewing environment of real YouTube users who experienced being inside a recommendation bubble through recreating a YouTube account with a similar viewing history. TheirTube shows how YouTube’s recommendations can drastically shape someone’s experience on the platform and, as a result, shape their worldview.

It seems that, with a representative sample, when you throw grit into a regression along with measures of intelligence, grit just explains very little on its own. Grit just doesn’t contribute much at all to educational outcomes and has limited application in job-market success. In fact intelligence “contributes 48–90 times more than grit to educational success.” 1 More study is needed etc etc and I’ll wait for a good metastudy but still, it really isn’t looking good.

But I have been a teacher for 20 years, despite not yet turning 40, and every day it became clearer and clearer that not all students had the same gifts. Yes, of course, some of this variation is environmental. Of course it’s complicated. Of course I’ll never be able to understand all the science. But the realities of teaching and of having grown up in a school system where some students were so similar in so many ways but had such vastly different outcomes just wore me down every day. And then I discovered the behavioral genetics research and its description of how, for example, adopted siblings growing up in the same house and family would go on to totally different academic outcomes. I did not celebrate. I did give in. Because life’s not fair, and neither is school. And pretending like everyone has an equal shot at succeeding in either is the greatest cruelty I know.

Many ingredients combine to give U.S. soft power its strength and reach, but entertainment and culture have always been central to the mix. Film and television have shaped how the world sees the United States—and how it perceives the country’s adversaries. Yet that unique advantage seems to be slipping away. When it comes to some of the great questions of global power politics today, Hollywood has become remarkably timid. On some issues, it has gone silent altogether.

The most glaring example is the growing wariness of U.S. studios to do anything that might imperil their standing with the Chinese government. China’s box office is as large as the American one, and entertainment is above all a business. So Hollywood sanitizes or censors topics that Beijing doesn’t like. But the phenomenon is not limited to China, nor is it all about revenue. Studios, writers, and producers increasingly fear they will be hacked or harmed if they portray any foreign autocrats in a negative light, be it Russian President Vladimir Putin or North Korean dictator Kim Jong Un.

Today, audiences can take their pick: there is no shortage of jingoistic U.S. films or televisions series, nor of material that challenges pro-American foreign policy orthodoxies. When it comes to how other great powers are portrayed, however, some hot-button topics are now off limits. American films dealing with the history and people of Tibet, a popular theme in the 1990s, have become a rare sight. There has never been a Hollywood feature film about the dramatic—and horrific—massacre in Tiananmen Square in 1989. The 2012 remake of Red Dawn initially centered on a Chinese invasion in the United States but was later rewritten to make North Korea the aggressor instead of China. And Variety called the 2014 blockbuster Transformers: Age of Extinction “a splendidly patriotic film, if you happen to be Chinese.”

Nothing has happened to change the fact that after ten years, riders have always been fundamentally unwilling to pay prices that would cover Uber’s actual costs, that Uber was always less efficient than the traditional taxis it drove out of business, that its only “efficiency improvement” was to push driver compensation to minimum wage levels, and that its growth depended entirely on unsustainable predatory subsidies.

There needs to be discussion about how to best restructure airlines, tourist and entertainment industries because they have contributed to overall economic welfare in the past, and clearly can in the future. Uber has only served to reduce overall economic welfare. Society has nothing to gain from “saving” Uber.

When James Baldwin visited San Francisco in 1963 to film a documentary  about U.S. racism, he encountered neighborhoods in turmoil: the city was seizing properties through eminent domain, razing them, and turning them over to private developers. Part of a massive, federal urban renewal program, nearly 5,000 families—no fewer than 20,000 residents, the majority of them people of color—were being displaced from rental homes, private property, and businesses in the Western Addition neighborhoods. Baldwin spoke to a Black teenager who had just lost his home and watched as his neighborhood was destroyed. He told Baldwin: “I’ve got no country. I’ve got no flag.” Soon after, Baldwin would say:  “I couldn’t say you do. I don’t have any evidence to prove that he does.”
