"The workouts we completed years ago may continue to influence and improve our health today, according to a fascinating new study of the current lives and health of people who joined an exercise study a decade before. The findings suggest that the benefits of exercise can be more persistent than many of us might expect, even if people are not exercising to the same extent as they previously did. But the impacts also may depend on the types and amounts of exercise involved."

"No matter what you call it - chroma key, green screen or blue screen - it's the film and video technique that gives your local TV weatherperson something in common with the Avengers movies: artificial backgrounds inserted behind the action. You simply record your subject in front of a solid green or blue screen, and then add a touch of software magic to change the background. Dozens of free or inexpensive apps allow you to use the technique on your own clips. It's a great way to jazz up your presentations and other videos - or to keep children busy with a weekend project filming their own toys in action scenes. Here's how to get started."

"Q. How do you take screen shots of articles and then post them on Twitter, with sections highlighted and the URL of the article included? A. Annotating screen shots of text passages - and then posting the image and a link to the article on Twitter - is an effective way to make a point with the selected text. It also lets you get around the service's 140-character limit. You can mark up the screen shot's text in a few different ways on a mobile device or computer."

""Many board members noticed that you were on your phone a lot," he said. "If you can hold out on texting friends or checking your Twitter feed until the breaks, that would be great." Mission failed. Now I did feel like an idiot. But I was also quite angry. The thing is, I hadn't checked my Twitter feed for over two hours. I'd been taking notes. I walked down the hall and began to think. I realized that my friends and I are glued to our phones all day long. That's just the way we are. Phones are crucial to our identities and lifestyle. Telling people in my generation to put our phones away is not a solution. Just ask our teachers how that has worked for them. Even so, the workplace is not ready for how often we are going to pull out our phones. Rather than fight it, I think the other generations are going to have to learn to let go and adapt to us. The reality is that social media breaks take less than 15 seconds and can be re-energizing. That's less time than the widely accepted practice of taking breaks for coffee or snacks. That said, there is no denying that we will need to be mentored so we know when even a 15-second break is unacceptable. The good news is that teachers have been trying to coach us about this for years. We can learn and we can adapt, if the other generations adapt, too."

"The benefits to companies are substantial. Many start-ups enlist their ambassadors as product testers and de facto customer service representatives who can field other teachers' queries. Apple, Google and Microsoft, which are in education partly to woo students as lifetime users of their products, have more sophisticated teacher efforts - with names like the Apple Distinguished Educators program, Google for Education's Certified Innovator Program and Microsoft Innovative Educator Expert program. Each yearlong program selects teachers to attend a conference and work with the company to help create, or develop, education innovations, often using company tools. The tech giants position their programs as professional development for teachers, not marketing exercises."

"Like a lot of children, my sons, Toby, 7, and Anton, 4, are obsessed with robots. In the children's books they devour at bedtime, happy, helpful robots pop up more often than even dragons or dinosaurs. The other day I asked Toby why children like robots so much. "Because they work for you," he said. What I didn't have the heart to tell him is, someday he might work for them - or, I fear, might not work at all, because of them. It is not just Elon Musk, Bill Gates and Stephen Hawking who are freaking out about the rise of invincible machines. Yes, robots have the potential to outsmart us and destroy the human race. But first, artificial intelligence could make countless professions obsolete by the time my sons reach their 20s."

"Most of us use web browsers out of habit. If you surf the web with Microsoft Edge, that may be because you use Windows. If you use Safari, that's probably because you are an Apple customer. If you are a Chrome user, that could be because you have a Google phone or laptop, or you downloaded the Google browser on your personal device after using it on computers at school or work. In other words, we turn to the browsers that are readily available and familiar. It's easy to fall into browser inertia because these apps are all fast, capable and serve the same purpose: visiting a website. So if the differences are minimal, why bother looking for something else? By the end of this column, I hope to persuade you to at least try something else: a new type of internet navigator called a private browser. This kind of browser, from less-known brands like DuckDuckGo and Brave, has emerged over the last three years. What stands out is that they minimize the data gathered about us by blocking the technologies used to track us."

"Google has now given us an option to set search and location data to automatically disappear after a certain time. We should all use it."

"WINTER GARDEN, Fla. - On the wall of a classroom that is home to the West Orange High School TikTok club, large loopy words are scrawled across a whiteboard: "Wanna be TikTok famous? Join TikTok club." It's working. "There's a lot of TikTok-famous kids at our school," said Amanda DiCastro, who is 14 and a freshman. "Probably 20 people have gotten famous off random things." The school is on a quiet palm-tree-lined street in a town just outside Orlando. A hallway by the principal's office is busy with blue plaques honoring the school's A.P. Scholars. Its choir director, Jeffery Redding, won the 2019 Grammy Music Educator Award. Amanda was referring to a different kind of stardom: on TikTok, a social media app where users post short funny videos, usually set to music, that is enjoying a surge in popularity among teenagers around the world and has been downloaded 1.4 billion times, according to SensorTower.

"Over the past three decades, a handful of products like Netscape's web browser, Google's search engine and Apple's iPhone have truly upended the tech industry and made what came before them look like lumbering dinosaurs. Three weeks ago, an experimental chat bot called ChatGPT made its case to be the industry's next big disrupter. It can serve up information in clear, simple sentences, rather than just a list of internet links. It can explain concepts in ways people can easily understand. It can even generate ideas from scratch, including business strategies, Christmas gift suggestions, blog topics and vacation plans."
