If you're already stressed out, treating an AI like it’s 'human' actually makes your anxiety worse.

Whether a talk with a political enemy goes well has almost nothing to do with what you're actually talking about.

Cracking down on people skipping transit fares has a massive mental benefit for everyone else that’s worth way more than the money.

A simple vaccine for diarrhea is actually one of the best ways to stop kids from suffering from lifelong malnutrition and stunting.

Electing a woman instead of a man causes an immediate, measurable drop in local crimes against women.

Giving cash to people in drug rehab doesn't actually lead to them spending that money on more drugs.

We're failing to stop malaria with free mosquito nets because of a myth that the chemicals in them go bad after a year.

Breaking AI safety rules isn't about how long you try—it's about how smart you are. Experts can do it in four turns.

Pandemic 'social bubbles' work just as well if you pair up with people who have similar work schedules instead of similar family sizes.

Banks that offer 'Islamic banking' options actually end up taking way bigger risks with their loans.

Tech giants might be faking their profits by pretending AI chips last ten years when they actually die in two.

Companies could get sued for 'waste' if they let good employees quit, just like if they let a multi-million dollar factory rot.

Policies meant to boost 'tourism' actually did a better job of cleaning up water pollution than actual environmental laws did.

Only about 4% to 7% of those big 'green hydrogen' projects people announce actually ever get finished on time.

If we want to fix the massive shortage of care workers, we need to start explicitly recruiting men for those jobs.

Democracies should have an 'immune system' that automatically gives citizens extra rights if a leader starts acting like a dictator.

Instead of charging money, we could give things out more fairly just by making the 'right' to use them expire really fast.

Prison inmates actually managed to hack the Argentine President’s house just by tricking a soldier with a digital scam.

In cultures where 'saving face' is a big deal, companies are way more likely to lie about their environmental record while actually doing a terrible job.

You can basically double a farm's output just by planting your veggies right under solar panels.

Researchers figured out they could trick a robot into handing someone a knife instead of an apple using nothing but a printed drink coaster.

Imagine wireless internet that's actually as fast as a physical cable—no lag, no matter how many devices the signal bounces through.

Scientists made 3D-printed lenses that turn sound into 'holograms' to literally remote-control specific neurons in your brain.

AI finally figured out the messy, chaotic way atoms are packed inside glass, solving a mystery that's stumped scientists for decades.

It turns out messy, 'cheap' glass might be way better at catching dark matter than the perfect crystals scientists usually use.

A single quantum AI 'brain cell' can predict the future better than a regular one, even when they’re looking at the exact same data.

There’s a new AI that’s officially started dreaming up its own theories about how physics works and then testing them out.

Scientists are using 'entangled light' to basically see through things and spot hidden details that a normal camera would miss.

By copying how seal whiskers work, robots can now 'see' invisible ripples underwater while ignoring their own vibrations.

Scientists used earthquake sensors to track a meteor as it zipped across the Alaskan sky in broad daylight.

You can actually sharpen a blurry MRI scan just by twisting two layers of metal mesh against each other.

Researchers built a tiny light source that can fire off individual light particles shaped into 3D holographic images.

A new type of audio amp actually runs on static, turning random electronic noise into a crystal-clear signal boost.

Scientists built a new amplifier that powers itself using nothing but tiny differences in temperature.

The keto diet can actually help 'reseal' the protective barrier around the spinal cord that gets wrecked by Multiple Sclerosis.

You can now tell if an ancient skeleton was male or female just by looking at the proteins stuck in their teeth.

Researchers made 'sentinel plants' that change how they look to tell you exactly how the invisible bugs in the soil are doing.

Going on a digital detox will definitely make you feel better, but it won't actually help you get more work done or focus any better.

Tell someone a snack is 'plant-based' and they probably won't want it. Tell them after they've eaten it, and they’re 37% more likely to buy it again.

If a mutual fund manager is married to a big-shot executive, they make way more money—but only when they're trading in their spouse’s industry.
