S9S23The Black Mambas: South Africa's all-female anti-poaching unit  Most anti-poaching units in Africa follow a familiar pattern: male rangers armed with rifles patrol the bush to catch those hoping to snare big game for the lucrative illegal trade in their body parts. One unit operating in the Olifants West Nature Reserve within the Greater Kruger National Park in South Africa is a bit different.The Black Mambas, named after the deadly snake, is the first all-female anti-poaching unit in South Africa. Since they were established in 2013, they've had a significant impact on local wildlife conservation. By removing snares and traps, the group claims to have reduced poaching significantly and eliminated rhino poaching within the reserve.

S25The genes that made us truly human may also make us ill  Over the past 15 million years, our ancestors acquired the genetic changes that eventually made us human, and separated us from our closest living relatives – the chimpanzee and other great apes.Our ancestors' brains quadrupled in size, allowing greater behavioural flexibility, while modifications to the tongue and vocal cords contributed to the development of human speech and language. Ancient humans acquired skeletal, muscle and joint modifications which allowed them to walk upright, move across large distances, and grasp and throw projectile weapons.

S37How Pit Viper Built 'Party Mountain' Out of Potty Humor and '90s Nostalgia  When Chuck Mumford first launched Pit Viper, the Salt Lake City-based sunglass company he founded with college buddy Chris Garcin in 2012, he picked up an old Samsonite briefcase at Goodwill, spray painted it neon colors, and filled it with a bunch of the outrageously bright military-grade sunglasses he'd designed."I would take it everywhere I went," Mumford says. "I was totally ruthless."

S7S41Sam Altman's Second Coming Sparks New Fears of the AI Apocalypse  Open AI's new boss is the same as the old boss. But the companyâand the artificial intelligence industryâmay have been profoundly changed by the past five days of high-stakes soap opera. Sam Altman, OpenAI's CEO, cofounder, and figurehead, was removed by the board of directors on Friday. By Tuesday night, after a mass protest by the majority of the startup's staff, Altman was on his way back, and most of the existing board was gone. But that board, mostly independent of OpenAI's operations, bound to a "for the good of humanity" mission statement, was critical to the company's uniqueness.As Altman toured the world in 2023, warning the media and governments about the existential dangers of the technology that he himself was building, he portrayed OpenAI's unusual for-profit-within-a-nonprofit structure as a firebreak against the irresponsible development of powerful AI. Whatever Altman did with Microsoft's billions, the board could keep him and other company leaders in check. If he started acting dangerously or against the interests of humanity, in the board's view, the group could eject him. "The board can fire me, I think that's important," Altman told Bloomberg in June.

S19Unifying Your Company Around a Moral Goal  In turbulent times, companies need a reliable anchor to guide decision-making. When organizations become moral communities, underpinned by purpose, they provide that stability for stakeholders as well as a reassuring sense of hope, solidarity, agency, and meaning. Three strategies can help. First, tell a big story about what your organization believes in and what it is trying to accomplish. Second, treat purpose as an organizing principle that guides company structure, strategy, and culture. Third, model courageous, purpose-driven leadership yourself.

S3S67What Hamas Promises, Iranians Know Too Well  Young Iranians can have no illusions about the mix of misogyny, anti-Semitism, and Islamism that Hamas and Iran’s rulers share.Of all the cataclysmic events I have ever experienced, October 7 affected me like no other. The videos of hateful protests and bloody or charred bodies unearthed memories I’d long kept buried. In one, I am a girl standing in the doorway of our home in Tehran, staring at graffiti that appeared overnight on a neighbor’s wall. Punctuated by a Swastika—something I had never seen before—were three words, scrawled in black paint on red brick: Kikes get lost.

S18Research: When -- and Why -- Employee Curiosity Annoys Managers  Researchers conducted a series of studies to understand when curiosity may lead to different reactions in the workplace. They found that curious employees were often seen by their leaders as insubordinate and, in turn, less likable. However, curious employees who were politically skilled were not seen this way. They distinguished between constructive curiosity, which involved seeking information, knowledge, or learning by asking many provocative questions that don’t have easy answers, and unconstructive curiosity, which involved seeking information, knowledge, or learning by asking too many questions and questions with easy answers. Their findings have implications for both managers, who should ensure they’re not dismissing employees expressing constructive curiosity, and employees, who should ensure they’re not engaging in unconstructive curiosity.

S20Taupo: The super volcano under New Zealand's largest lake  Located in the centre of New Zealand's North Island, the town of Taupo sits sublimely in the shadow of the snow-capped peaks of Tongariro National Park. Fittingly, this 40,000-person lakeside town has recently become one of New Zealand's most popular tourist destinations, as hikers, trout fishers, water sports enthusiasts and adrenaline junkies have started descending upon it.The namesake of this tidy town is the Singapore-sized lake that kisses its western border. Stretching 623sq km wide and 160m deep with several magma chambers submerged at its base, Lake Taupo isn't only New Zealand's largest lake; it's also an incredibly active geothermal hotspot. Every summer, tourists flock to bathe in its bubbling hot springs and sail through its emerald-green waters. Yet, the lake is the crater of a giant super volcano, and within its depths lies the unsettling history of this picturesque marvel.

S13Return-to-Office Plans Don't Have to Undermine Employee Autonomy  In recent years, organizations have been hard at work reviewing, renewing, articulating, and disseminating their corporate purpose. Renewed corporate purpose statements have more explicitly centered human-centric values, such as employee well-being, growth, and inclusion. This has been a good thing: Gartner research shows that businesses who put these human-centric values front and center see better talent and business outcomes. However, return-to-office mandates, if not done strategically and transparently, can feel like an about-face in employee flexibility, autonomy, and well-being, and starkly at odds with a human-centric corporate purpose. The authors identified three imperatives to help leaders navigate the return-to-office revolution in a way that strengthens, rather than damages, employees’ connection to the organization and its purpose.

S6S26Brazil's politicians, unions, and workers can't agree on how to protect gig labor  While on the campaign trail in 2022, Brazilian President Luiz Inácio Lula da Silva made it clear he wanted to take on gig work platforms. “We’re not against someone working [by] delivering food on a bike,” said Lula during a union event in April of that year. “What we’re against is them not being respected as workers. We’re against them not having rights.” As president, he vowed he would establish regulation to give the workers “a minimum of social security.”A few months after he was sworn in, Lula called together labor groups, representatives for gig work platforms, and government officials to create a working group that would craft new rules for the industry — the first step in making good on his promise. But barely a year after winning the presidency, the dream of gig work regulation in Brazil may be slipping away. Lula’s working group disbanded prematurely in late September, and there is little consensus on how Congress should proceed. Experts now fear that Brazil may have missed a valuable chance to regulate gig work, potentially leaving workers even worse off than before.

S32'A Shot in the Arm' Documentary Treats Vaccine Denialism with a Dose of Empathy  A pandemic film shows that compassion and civil dialogue might be the best antidote to vaccine distrustGlobal vaccination trends are telling us both good news and bad news stories, nearly four years after the start of a global pandemic. On the plus side, some childhood immunizations have begun recovering to pre-COVID rates. Against that, almost half of the 73 countries that reported pandemic-related declines in vaccine rates have either flatlined or continue to drop. Also on the downside, UNICEF reported earlier this year that public trust in vaccinations had eroded worldwide. And that includes the U.S., where one new pandemic documentary aims to probe (and show ways to ease) this distrust.

S24What eating a big meal does to your body  Eating plays a big part in our lives at this time of year. But what happens if we indulge a little too much?I am pretty confident that I can predict how I am going to feel after a big meal: snoozy, sluggish and definitely full. But by lunchtime the next day I am sure I will find room for another roast. When you think about it, it is pretty weird that the day after an enormous meal we can eat exactly the same quantity again. Did we not learn our lesson the first time?

S50Grinding scientists: How mechanochemistry could revolutionize the creation of new materials  The archetypal image of chemistry is a set of glassware, full of colorful liquids about to be mixed. Froth, bubbles, and smoke ensue. Much of industrial chemical synthesis is a tamer version of this. But could we replace the bubbling flask with the slow grind of a ball mill? A scientific review article details progress in the field of mechanochemistry, investigating this question.Most traditional chemical syntheses rely on random thermal motion driven by mixing to bring reactants together. Solvents dissolve materials into fluid form, and the dissolved materials are comingled, stirred, heated, filtered, and distilled to create and isolate new compounds. Electrochemical synthesis drives a reaction with an electrical current. Electrolysis of water to liberate hydrogen and oxygen is one example. Photochemistry uses light to drive reactions, with photosynthesis being an abundant natural demonstration. The breakdown of plastic under prolonged sunlight is another. (Nanofabrication, if it is possible, would synthesize molecules by using tiny machines to pluck atoms out of bins and poke them together.)

S8S46The "action fallacy" tells us that the most effective leaders are unseen  “Leadership is about overcoming crises.” “Leadership is about acting when others hesitate.” Management blogs, consulting pitches, and social media posts are rife with similarly catchy leadership clichés. As a historian teaching at a business school, however, I know that such simple wisdom corresponds little to how history’s most influential leaders actually achieved great things. Nor, I suspect, does it apply to leaders today. So what wisdom does apply? I decided to undertake a study to answer that question. Here’s what I found out.When you think of history’s great leaders, who comes to mind? Napoleon, JFK, Churchill, or one of the other great statesmen who combined charisma with a penchant for action? Or perhaps Ernest Shackleton, the fearless British explorer, whose epic struggle for survival aboard the ice-bound Endurance is a pillar of today’s business school curriculums and a never-ending stream of bestsellers.

S70A Moral Case Against the Israeli Hostage Deal  Early this morning, Hamas and Israel agreed to a hostage deal: 30 children and 20 women will return to Israel, in exchange for five days of cease-fire and 150 Palestinians who are in Israeli custody and have been accused or convicted of serious crimes. Each additional 10 Israeli hostages freed will buy another day of respite from fighting. In arguing for the deal, Prime Minister Benjamin Netanyahu called the return of hostages “a sacred duty” and quoted the 12th-century sage Maimonides, to the effect that redeeming Jewish prisoners (pidyon shvuyim) is a great mitzvah. (Islam commands a similar duty to free prisoners.) Netanyahu omitted mention of the various restrictions on this blessed activity—the most important of which is not to overpay for hostages, or do anything else that might encourage more hostage-taking. The far-right segment of his government split on the deal, with three ministers from the very-very-far-right Otzma Yehudit voting nay and 35 others consenting. The only-slightly-less-far-right Religious Zionist Party eventually voted yes on the deal.For the moment, the mood inside Israel is tentative relief—which will turn to immense relief the moment the children start crossing the border and running into their families’ arms. (Two of the Israeli children on the exchange list are relatives of Yifat Zaila, whom I spoke with in Israel a few weeks ago.) Under these circumstances, one understands why Netanyahu might have ignored the other part of Maimonides’s recommendation. Anyone who wants to think about cold calculus now, however, might consider a document that makes the case against paying for the freedom of hostages. “We maintain that no compensation should be given” for the freedom of the innocent, it says. To pay for freedom would be “a surrender of the great fundamental principle” that hostages are not the property of hostage-takers, and that “if compensation is to be given at all, it should be given to the outraged and guiltless” victims of the crime, rather than to the criminals themselves.
