Could you stand on the surface of Jupiter? Exploring the enigmatic outer planets

Could you stand on the surface of Jupiter? Exploring the enigmatic outer planets    

I get some pretty great questions from kids once they learn that I’m an astronomer. Several children have asked me if it is possible to stand on the surface of Jupiter. We know Jupiter has lots of clouds and a thick atmosphere. But if you went deep enough, and assuming you were not crushed by atmospheric pressure or the planet’s gravity, would you find land that you could stand on? To answer that question, we first need to peek under the clouds to get a feel for what these planets are like.As you descend into the atmosphere of the outer planets, two things happen: It gets hotter, and the pressure rises. Jupiter and Saturn are gas giants made of mostly hydrogen and helium. At a certain depth, the hydrogen, along with perhaps some liquid helium, compresses into an ocean. Jupiter’s ocean might be the largest in the Solar System, and it is so pressurized that the hydrogen loses its electrons, turning it into liquid metal. As it moves, this ocean creates an electrical current that gives Jupiter a magnetic field 15 times the size of the Sun. It is the largest magnetic field of any planet in the Solar System.

The Messy US Influence That's Helping Iranians Stay Online    

The United States Treasury announced on Friday that it is sanctioning the Iranian technology company Arvan Cloud, along with two senior employees of the company and an affiliated firm based in the United Arab Emirates. Officials from both the Treasury and the US State Department said on Friday that the company has close ties to Iran's Information and Communications Technology Ministry and plays a key role in providing infrastructure for the regime's surveillance activities and restrictive intranet known as the National Information Network (NIN).US sanctions against Iran are extensive, and the Treasury's Office of Foreign Assets Control has issued a number of sanctions specifically related to the Iranian government's long-standing attacks on internet freedom and digital access within the country. The full scope of US sanctions against Iran have already significantly isolated the country's economy, and its government's own internet shutdowns, digital blocking, and censorship have only further fueled financial hardship. But a US government official told WIRED on Friday that the Biden administration has seen consistent evidence that naming and shaming regime collaborators stifles an impacted company's ability to recruit top talent within the country.

Working with Chronic Pain: Our Favorite Reads    

It really was, at least before the world shifted to hybrid work. Rather than sitting quietly at my desk, breathing deeply, and pushing through the pain, I was able to walk to my bed and take a 30-minute nap in the middle of the day. Rather than using up chunks of vacation time to recover from a migraine, I could take advantage of the flexibility and still be able to get work done.

Ask Ethan: How do magnetic fields split energy levels?    

One of the most remarkable things about physics is how universal it is. If you take the same species of atomic nucleus — with a fixed number of protons and neutrons — then there will only be a fixed set of energy levels that the electrons orbiting that nucleus can occupy. As the electrons transition between the various energy levels, they emit (as they fall to lower energy levels) and absorb (as they rise to higher energy levels) photons of a very specific wavelength and energy: only those wavelengths and energies allowable by the rules of quantum mechanics. The values for these energy levels are universal: the same for all atoms of the same species everywhere and at all times throughout the Universe.Until, that is, you apply either an external electric or magnetic field. All of a sudden, these energy levels split, and take on a great variety of values, with the amount of splitting depending entirely on the strength of the field applied. But how is this possible? That’s what Jon Coal wants to know, asking:

You're Not Powerless in the Face of Imposter Syndrome    

Research shows that high achievers from underrepresented backgrounds often find themselves confronting imposter syndrome or feeling they don’t fit in, are not welcome, or don’t belong. But understanding imposter syndrome does little to end it. The author, who studied underrepresented board members for his PhD and who interacts with hundreds of aspiring and existing board directors in his role at an executive search firm, has found that attributes of moxie — strength of will, self-discipline, and the ability to persist despite challenges — were vital to underrepresented directors’ success. He recommends four tactics to help make moxie your own super power.

How to Keep Working When You're Just Not Feeling It    

Motivating yourself is one of the main things that sets high achievers apart, and it’s hard. How do you keep pushing onward when your heart isn’t in it? In her research, Fishbach has identified some simple tactics: Set goals that are intrinsically rewarding, and make them very specific. If a task isn’t satisfying, focus on aspects of it that are or combine it with pleasant activities. Reward yourself in the right way for getting things done. To avoid slumps, break objectives into subgoals; look at how much you’ve accomplished until you’re halfway there; and then count down what you have left to do. And use social influence: Let high performers inspire you, boost your get-up-and-go by giving advice, and keep the people you want to succeed for front of mind.

The Instagram Founders' New News App Is Actually an AI Play    

The invasion of chatbots has disrupted the plans of countless businesses, including some that had been working on that very technology for years (looking at you, Google). But not Artifact, the news discovery app created by Instagram cofounders Kevin Systrom and Mike Krieger. When I talked to Systrom this week about his startup—a much-anticipated follow-up to the billion-user social network that's been propping up Meta for the past few years—he was emphatic that Artifact is a product of the recent AI revolution, even though it was devised before GPT began its chatting. In fact, Systrom says that he and Krieger started with the idea of exploiting the powers of machine learning—and then ended up with a news app after scrounging around for a serious problem that AI could help solve.That problem is the difficulty of finding individually relevant, high-quality news articles—the ones people most want to see—and not having to wade through irrelevant clickbait, misleading partisan cant, and low-calorie distractions to get those stories. Artifact delivers what looks like a standard feed containing links to news stories, with headlines and descriptive snippets. But unlike the links displayed on Twitter, Facebook, and other social media, what determines the selection and ranking is not who is suggesting them, but the content of the stories themselves. Ideally, the content each user wants to see, from publications vetted for reliability.

The #1 rideshare app in Japan isn't Uber, it's a taxi app    

To anyone who’s ever used a ride-hailing app, Go’s front page is a familiar sight. Car icons crawl through a street map in shades of pastel, while a blue map pin indicates the pickup point. A user connects their payment card, enters their destination, and a car arrives to whisk them on their way.Except this app hails taxis, unlike Uber and Didi’s private cars. Go is Japan’s highly successful taxi app, with a network of 100,000 cabs aggregated from multiple local taxi companies. Thanks to regulation that effectively bans Uber and Didi from operating private car-sharing services, Go commands 70% of the mobility market in Japan. In May, the company drew funding from Goldman Sachs that pushed it above the $1 billion valuation mark, making it the latest in Japan’s small group of unicorns.

The AI Hype Cycle Is Distracting Companies    

Machine learning has an “AI” problem. With new breathtaking capabilities from generative AI released every several months — and AI hype escalating at an even higher rate — it’s high time we differentiate most of today’s practical ML projects from those research advances. This begins by correctly naming such projects: Call them “ML,” not “AI.” Including all ML initiatives under the “AI” umbrella oversells and misleads, contributing to a high failure rate for ML business deployments. For most ML projects, the term “AI” goes entirely too far — it alludes to human-level capabilities. In fact, when you unpack the meaning of “AI,” you discover just how overblown a buzzword it is: If it doesn’t mean artificial general intelligence, a grandiose goal for technology, then it just doesn’t mean anything at all.

When Should You Get a Mammogram?    

Medical boards and task forces recommend mammogram screenings for breast cancer begin at age 40. But people in high-risk groups may want to consider getting tested even earlierWhen it comes to detecting breast cancer, regular testing matters. But precisely how early and how often you should get screened isn’t so straightforward. Medical guidance can seem bewilderingly inconsistent. Some agencies recommend annual checks from age 40 onward, for example, while others have said to wait until age 50. There is no “generalizable” age that can be applied to everyone, says Vivian Bea, section chief of breast surgical oncology at New York–Presbyterian Brooklyn Methodist Hospital.
