Robert Sansone is a natural-born engineer. From animatronic hands to high-speed running boots and a go-kart that can reach speeds of more than 70 miles per hour, the Fort Pierce, Florida-based inventor estimates he’s completed at least 60 engineering projects in his spare time. And he’s only 17 years old.

A couple years ago, Sansone came across a video about the advantages and disadvantages of electric cars. The video explained that most electric car motors require magnets made from rare-earth elements, which can be costly, both financially and environmentally, to extract. The rare-earth materials needed can cost hundreds of dollars per kilogram. In comparison, copper is worth $7.83 per kilogram.

“I have a natural interest in electric motors,” says Sansone, who had used them in different robotics projects. “With that sustainability issue, I wanted to tackle it, and try and design a different motor.”

The high schooler had heard of a type of electric motor—the synchronous reluctance motor—that doesn’t use these rare-earth materials. This kind of motor is currently used for pumps and fans, but it isn’t powerful enough by itself to be used in an electric vehicle. So, Sansone started brainstorming ways he could improve its performance.

Over the course of a year, Sansone created a prototype of a novel synchronous reluctance motor that had greater rotational force—or torque—and efficiency than existing ones. The prototype was made from 3-D printed plastic, copper wires, and a steel rotor and tested using a variety of meters to measure power and a laser tachometer to determine the motor’s rotational speed. His work earned him first prize, and $75,000 in winnings, at this year’s Regeneron International Science and Engineering Fair (ISEF), the largest international high school STEM competition.

There are few things worse than feeling disappointed. The big opportunity you were made to get excited about suddenly evaporates, or the new relationship you thought was really gaining traction vanishes into thin air.

If these scenarios sound familiar to you, it’s likely you’ve been ‘breadcrumbed’.

Hansel and Gretel associations aside, put simply, ‘breadcrumbing’ involves leading someone on, and keeping their hopes up through small and superficial acts of interest. A breadcrumber might be flirtatious, complimentary, or seem engaged with you at first, but will ultimately end up disappointing you with empty promises and emotional abandonment.

And breadcrumbing isn’t just limited to relationships. It can happen in the workplace, within families, friendships, and on social media.

However, the good news is that there are some key signs that make it easy to spot.

There’s a lot going on in the world that can contribute to high levels of stress, from rising gas prices to surging inflation. Even so, there are a few simple rituals that always bring me happiness: cuddles with my puppy, reading before work, getting some exercise, and even that first sip of coffee. I’m leaning into these small things that make a difference in my day.

Sure, a cup of coffee won’t change whether you feel truly fulfilled — but in uncertain times, there’s value in boosting your mood when you can.

Hormones (a type of chemical your body makes) that trigger feelings of happiness, and each chemical is connected to specific events or rewards. Understanding these chemicals and how they work can help you figure out even small ways to feel better amid such a stressful time

Matt Edmondson, a federal agent with the Department of Homeland Security for the last 21 years, got a call for help last year. A friend working in another part of government—he won’t say which one—was worried that someone might have been tailing them when they were meeting a confidential informant who had links to a terrorist organization. If they were being followed, their source’s cover may have been blown. “It was literally a matter of life and death,” Edmondson says.

“If you’re trying to tell whether you’re being followed, there are surveillance detection routes,” Edmondson says. If you’re driving, you can change lanes on a freeway, perform a U-turn, or change your route. Each can help determine whether a car is following you. But it didn’t feel like enough, Edmondson says. “He had those skills, but he was just looking for an electronic supplement,” Edmondson explains. “He was worried about the safety of the confidential informant.”

After not finding any existing tools that could help, Edmondson, a hacker, and digital forensics expert, decided to build his own anti-tracking tool. The Raspberry Pi-powered system, which can be carried around or sit in a car, scans for nearby devices and alerts you if the same phone is detected multiple times within the past 20 minutes. In theory, it can alert you if a car is tailing you. Edmondson built the system using parts that cost around $200 in total and will present the research project at the Black Hat security conference in Las Vegas this week. He’s also open-sourced its underlying code.

When I was first dating my future wife, we went to an event that required us to go through a metal detector. The guard stopped me and our exchange went like this:

Guard: “Hey. You and her–are you together?”

Me: “Together? I mean, things are going well, but I don’t want to put a label on it.”

Future wife (laughing): “OMG. He wants to know if he can put our jackets in the same bin.”

I admit it: I’m an over-thinker. Are you? If you had been there, would you have laughed? Or would you have thought: “Gosh, that could totally have been me?”

I’d like to know your answer, but I’d also like to explain the reasoning behind the “You and her together?” story, which I’ve told more times and to more people than I can remember.

In Uttar Pradesh, India, where I grew up, temperatures can soar as high as 120 degrees in May and June. But very few people have access to an air conditioner.

With a per capita income of around a $1,000 a year, many people in this part of the country can’t afford to buy an A/C unit or pay the power bills that come with using one.

So how do people keep cool?

That’s a question that people are asking themselves as the world faces unprecedented heat waves, including in the U.S. Pacific Northwest and Europe, where many do not have air conditioners. Severe heat has already killed thousands of people this summer.

Yet people in India and in other countries across the Global South have long figured out ways to deal with the horrible heat. And so, I’d like to share a few tips on how to stay cool that I’ve learned from my upbringing and elders in Uttar Pradesh. Some of the advice is just what you’d think – like drinking lots of liquids and staying out of the sun – but others might surprise you.
