Smoking May Compromise Immune Health, Even Years After Quitting - Scientific American (No paywall)    

Numerous factors shape how a person’s immune system reacts to infections and other challenges. Age, sex and genetics are fundamental contributors—as the COVID pandemic highlighted. Now a new study shows that smoking has an equally important impact on certain immune responses, with some of its effects possibly lasting well beyond when a person quits.To explore which environmental factors had the biggest role, researchers measured the production of cytokines—key messenger molecules that mediate inflammation—in the blood of 1,000 healthy people after exposing the samples to either bacteria, fungi, antibodies or other agents known to elicit an immune response. Smoking was found to greatly alter both the innate response—the body’s general and immediate first line of defense—and the slower, more threat-specific adaptive response. The data suggest that the cytokine secretion in the innate immune response rapidly returns to the level of nonsmokers after a person quits smoking but that the effects on the adaptive response appear to endure for years or decades through a process called epigenetic memory. The results were published today in Nature.

What does 'pasture-raised' really mean? - National Geographic (No paywall)    

Many chickens fear open spaces, which leave them vulnerable to predators from above. Unless these open spaces are well-designed with trees, brush cover, or even solar panels, “pasture-raised” hens may never experience the pasture. Still, when it comes to chicken welfare, pasture-raised sets the highest standards, and the label indicates the hens can spend most of their day outside—if they want.To get the “free range” label, hens must have outdoor access for at least half of their lives, but like “pasture raised,” there are few requirements for what that outdoor space should look like—it could be concrete rather than grass, for example. And “cage-free” means only that hens aren’t in cages, but they may be kept indoors 24 hours a day. If a carton of eggs has none of these labels, the hens likely lived in battery cages, usually all-wire, communal enclosures in which each bird has 67 to 86 square inches. (For reference, a standard piece of printer paper is 93.5 square inches).

As a young girl growing up in Tennessee, Anna Mae Bullock liked to sing and recite movie dialogue to entertain her family. By age 20 she had a new name—Tina Turner—and a burgeoning music career with her partner, Ike. But behind the scenes, he was abusing her. Eventually, she found the courage to leave him and move on as a chart-topping, world-touring solo artist. She now lives out of the spotlight in Switzerland and recently released a new book, Happiness Becomes You.

Will Marvel's 'Fantastic Four' Copy The Best Sci-Fi Show On TV?    

The Fantastic Four are back, and now they’re in the Marvel Cinematic Universe. But will their movie be a period piece? On Valentine’s Day, Marvel Studios released a tantalizing promo image with several Easter eggs. Two particular details suggest that not only will Marvel’s Fantastic Four be set in the 1960s, it could introduce an alternate history of spaceflight to the MCU. If any of this sounds familiar, it should; an alternate spaceflight timeline is a very popular sci-fi trope right now. Is Marvel borrowing a premise from For All Mankind? In our timeline, the first issue of The Fantastic Four dropped in the fall of 1961. Like many popular Marvel characters, this superhero team comes from the Silver Age, making them all a bit edgier than their Golden Age predecessors. The early tone and writing of The Fantastic Four is a perfect example of Jack Kirby and Stan Lee honing the Marvel formula, and whatever you think of the MCU, those comics are a great example of how we got here. But is this movie going back to its ‘60s roots?

Could mysterious marine fungi save us from antibiotic resistance? - New Scientist (No paywall)    

TAKE a walk along a seashore almost anywhere in the world and you will probably see colourful patches of life growing on rocks, sea walls and driftwood. These are lichens, mutualistic partnerships between fungi and algae. In Britain, that might include the brightly coloured orange sea lichen and the yellowish maritime sunburst lichen, plus many other drabber species.Lichens are usually seen as land-living organisms and, indeed, the vast majority are, growing ponderously on inland rocks, tree trunks, leaves and soil. But coastal ones aren’t accidental vagrants from the land: they are marine-adapted species found only on or very near the shore. Until recently, they were thought to be outliers in the almost completely landlubbing kingdom of the fungi. Not any more. “In every marine ecosystem we look at, we find fungi,” says Michael Cunliffe at the University of Plymouth, UK.

Did Pluto ever actually stop being a planet? Experts debate. - National Geographic (No paywall)    

Declared the ninth planet in our solar system after its discovery in 1930 by American astronomer Clyde Tombaugh, Pluto is small, marble-colored, and became quickly beloved thanks to its association with Mickey Mouse’s pet dog (who was originally named Rover but renamed after the planet in 1931).To celebrate the 94th anniversary of Pluto’s discovery, we sat down with Brown and Philip Metzger, retired planetary physicist at NASA’s Kennedy Space Center (and current associate scientist at the University of Central Florida), to get some answers. Are Brown and likeminded people correct in reducing Pluto’s significance and instead focusing on new discoveries like the yet-unconfirmed “Planet Nine”? Or do Metzger and others have a solid argument for the triumphant return of Pluto?

The obesity pay gap is worse than previously thought - The Economist (No paywall)    

Obese people experience discrimination in many parts of their lives, and the workplace is no exception. Studies have long shown that obese workers, defined as those with a body-mass index (BMI) of 30 or more, earn significantly less than their slimmer counterparts. In America, several state and local governments are contemplating laws against this treatment. On November 22nd, one such ban came into force in New York City.Yet the costs of weight discrimination may be even greater than previously thought. “The overwhelming evidence,” wrote the Institute for Employment Studies, a British think-tank, in a recent report, “is that it is only women living with obesity who experience the obesity wage penalty.” They were expressing a view that is widely aired in academic papers. To test it, The Economist has analysed data concerning 23,000 workers from the American Time Use Survey, conducted by the Bureau of Labour Statistics. Our number-crunching suggests that, in fact, being obese hurts the earnings of both women and men.

The Other Time America Panicked Over a President's Age - The Atlantic (No paywall)    

One spring day in 1984, I was chatting with Burns “Bud” Roper, the veteran pollster. At the time, I was The Wall Street Journal’s White House correspondent, covering Ronald Reagan’s reelection campaign. Thanks to a surging economy, Reagan seemed poised for an easy victory in November. The campaign was shaping up to be a bore. “Bud,” I asked, “is there any chance he could lose?”When it came to polling, Bud had seen it all, going back to Harry Truman versus Thomas Dewey. He told me he hadn’t found anything that could stop Reagan. Then he paused. “Actually, there is one thing,” he added. “People won’t say it if you ask them directly, but when you look deeply at the numbers, a lot of them are concerned about his age.” Reagan was 73 at the time.

Hydrogen can play a key role in Australia’s energy transition by giving us additional ways of storing and moving energy around. As the world shifts towards cleaner energy production, there’s a push to make hydrogen production cleaner as well. In Australia, low-emission hydrogen is produced in two main ways. One method produces what is known as “green hydrogen”. It uses electricity produced from renewables – such as solar, wind or hydro – to “crack” water into separate streams of hydrogen and oxygen.

How newly discovered brain cells have made us rethink the human mind - New Scientist (No paywall)    

IT IS strange to think that we still don’t know what our brains are made of. Yet, despite decades of research and the development of high-tech scanning techniques, that is the truth. Sure, we know the basics. The average human brain weighs approximately 1.4 kilograms and has the consistency of soft tofu. It is made up of two general cell types: neurons, which do the thinking, and glia, which support them. But beneath this simple description lies a mind-boggling complexity – a complexity that continues to surprise even neuroscientists.Everyone knows neurons, the cells that send electrical impulses between different areas of the brain. Your brain contains around 86 billion of them and they come in many different varieties depending on their shape, function and properties. But there is still a lot we don’t know about them. Take rosehip neurons, which were discovered in 2018. Named for their shape, the cells seem to damp down the electrical activity of other neurons. Intriguingly, there is no equivalent cell in mouse brains, despite the fact that mice tend to have analogues of other human brain cells. We don’t really know much about what they do in the human brain, says Rebecca Hodge at the Allen Institute for Brain Science in Seattle, Washington, who was part of the team that discovered the cells.

Netflix Just Quietly Released the Year's Best Disaster Thriller    

Having watched their Norwegian neighbors make a decent stab at the Hollywood-style disaster movie with a loosely related trilogy of films about avalanches (The Wave), earthquakes (The Quake), and oil rig explosions (The Burning Sea), Sweden decided to get in on the action themselves last year with The Abyss (or Avgrunden, if you don’t want to get confused with James Cameron’s similarly perilous underwater epic). And they didn’t have to look far for inspiration, either.Out now on Netflix six months after being released in Scandinavia, the quasi-blockbuster is set in the real-life Kiruna, the country’s northernmost town, which in 2014 had to slowly start moving three kilometers east due to the threat of mining subsidence.

The Big Decisions that Impact Your Career - Harvard Business Review (No paywall)    

A career is a marathon not a sprint — and yours will benefit from a good strategy. Here are four smart choices you can make when you’re young that will help you reach success in the future. Work at companies that specialize in your skillset. Having a couple of recognizable brand names on your resume — specifically brands that have a strong reputation in your sector — can help you stand out from the crowd. Work with the best people that you can: people who have impressive experiences, people with a track record of success, and people with whom you can see yourself keeping in touch long-term. Look for opportunities to stretch yourself. If you use your first few jobs to gain a deep understanding of the roles and departments that exist within your sector — and how they work together to meet their collective goals — you will be a more competitive candidate for leadership roles down the line. Don’t get distracted by shortcuts. The truth is that there will never be a substitute for doing great work and building out strong experiences.

Whiting and Watts introduced this measure as “pq common sense,” defining common sense as the fraction of claims (q) that are shared by a fraction of people (p). For the study, they had 2,046 people rate 4,407 claims in categories ranging from practical truths to philosophical statements in topics such as geography, mathematics, and culture. Survey participants also classified claims based on their viewpoints of fact versus opinion, literal language versus figures of speech, and knowledge versus reasoning.“We find that plainly worded facts, like claims about physical reality, are the most commonsensical,” Whiting explained. (For example, plants need nutrients in the soil for them to grow.) However, people more aware of others’ emotions exhibited more common sense, and demographics such as age, education, or a person’s political leanings didn’t significantly influence results, he said.

The Psychology Behind Unethical Behavior - Harvard Business Review (No paywall)    

Leaders are often faced with ethical conundrums. So how can they determine when they’re inching toward dangerous territory? There are three main psychological dynamics that lead to crossing moral lines. First, there’s omnipotence: when someone feels so aggrandized and entitled that they believe the rules of decent behavior don’t apply to them. Second, consider cultural numbness: when others play along and gradually begin to accept and embody deviant norms. Finally, when people don’t speak up because they are thinking of more immediate rewards, we see justified neglect. There are several strategies leaders can use to counter these dynamics, including relying on a group of trusted peers to keep you in check, keeping a list of things you will never do for profit, and looking out for ways you explain away borderline actions.On a warm evening after a strategy off-site, a team of executives arrives at a well-known local restaurant. The group is looking forward to having dinner together, but the CEO is not happy about the table and demands a change. “This isn’t the one that my assistant usually reserves for me,” he says.

'Madame Web' Proves the Worst Superhero Movie Trend Needs to Go Away Forever    

Kevin Feige was on to something when he chose to steer Marvel away from superhero origin stories. In 2014, the Marvel Studios exec claimed that Doctor Strange would be the last origin story in the franchise’s cinematic universe, and while that hasn’t entirely been the case (see Shang-Chi, Captain Marvel, Moon Knight, or She-Hulk), Marvel’s subversive strategy has served it pretty well. The past decade has seen new heroes and villains introduced in seamless fashion, with each entry of the MCU serving as a back-door pilot, of sorts, for adventures to come. Sony’s Spider-Man universe is relatively young: it’s only been around for half a decade, but not for lack of trying. The studio has held the rights to the eponymous webhead for the past 25 years, and has tried to get a genuine franchise off the ground at least twice before. Though Sony is now leasing Peter Parker out to Marvel Studios, the studio hasn’t stopped trying to establish a comprehensive web of heroes and villains to set itself apart from the MCU.

People Don't Want to Be Compared with Others in Performance Reviews. They Want to Be Compared with Themselves - Harvard Business Review (No paywall)    

Why do people hate performance reviews? Maybe because, according to surveys, most of us don’t think they’re fair. A team of researchers set out to examine this in more detail. In four studies based on the data collected from 1,024 American and Dutch employees, they compared two types of reference points: employees who were compared against each other, and employees whose current performance was compared against their own past performance. The latter seemed to be perceived as far more fair — in that case, participants believed that the evaluations were more individualized, believing that the manager incorporated specific information about them. Thus, they considered that the evaluations were more discerning and accurate, and that they had been treated in a more respectful way.People hate performance evaluations. They really do. According to a survey of Fortune 1,000 companies done by the Corporate Executive Board (CEB), 66% of the employees were strongly dissatisfied with the performance evaluations they received in their organizations. More strikingly, 65% of the employees believed that performance evaluations were not even relevant to their jobs.
