The Myth of the 5 A.M. Club: Why Early Isn’t Always Best

There’s a persistent myth in our culture that success and downright virtue belong to the early risers—those “5 a.m. club” members who rise before the sun and conquer their to-do lists while the rest of us are still snoozing. Social media is flooded with images of pre-dawn productivity, and best-selling books tout the virtues of… Continue reading The Myth of the 5 A.M. Club: Why Early Isn’t Always Best

A New Geometry for Einstein’s Theory of Relativity

Kunzinger and Sämann wanted to use their new way of estimating curvature to determine whether these singularity theorems would still be valid if they no longer assumed space-time is smooth. Would singularities persist even in rougher, more realistic-looking spaces? It’s important to find out if the smoothness condition can be waived, Sämann said, because doing… Continue reading A New Geometry for Einstein’s Theory of Relativity

Healthy Sleep Is a Community Issue

This commentary was originally published by The Baltimore Sun on June 26, 2025. Healthy sleep is often viewed as a matter of personal responsibility—setting a consistent bedtime, avoiding caffeine, and limiting screen time before bed. While these individual habits are important, new research led by researchers at RAND and the University of Pittsburgh suggests that… Continue reading Healthy Sleep Is a Community Issue

Testing Sperm Health with a Mechanical Engineering Twist

Rachel Feltman: For Scientific American’s Science Quickly, I’m Rachel Feltman. The World Health Organization estimates that infertility impacts one in six adults globally. But when it comes to addressing infertility, male partners are often left out of the equation. Some studies suggest that in 18 to 27 percent of cases where a heterosexual couple seeks… Continue reading Testing Sperm Health with a Mechanical Engineering Twist

The U.S. Power Grids Need AI Disclosure Requirements

The electrical grid is a complex system that is managed for reliability above all else—in no small part because it supports other life-sustaining services like water systems and telecommunications. Increasingly, though, electric utilities are turning to artificial intelligence (AI) to help manage power demand and assist in decisionmaking. While this has the potential to enhance… Continue reading The U.S. Power Grids Need AI Disclosure Requirements

Futuristic Radio Telescope Will Spot Baby Solar Systems—If It’s Funded

New Mexico’s Plains of San Agustin are otherworldly: Silence, sand and sharp plants reign on the valley floor. Knobbly volcanic rock rises above. Pronghorns’ legs and jackrabbits’ ears break up the landscape. And so, too, does one of the world’s largest telescopes. The plains house the aptly named Very Large Array (VLA)—a radio telescope made… Continue reading Futuristic Radio Telescope Will Spot Baby Solar Systems—If It’s Funded

Countering Russian Influence: Support for Armenia, Georgia, and Moldova in the ‘Waiting Room of the West’

As Europe rallies to support Ukraine’s defence and fortify its own security, three other post-Soviet states—Armenia, Georgia, and Moldova—remain dangerously exposed to Russian coercion. Each has expressed a desire to move closer to the West: Moldova and Georgia are official EU candidates, and all three participate in the European Union’s Eastern Partnership. Yet despite these… Continue reading Countering Russian Influence: Support for Armenia, Georgia, and Moldova in the ‘Waiting Room of the West’

How Distillation Makes AI Models Smaller and Cheaper

The Chinese AI company DeepSeek released a chatbot earlier this year called R1, which drew a huge amount of attention. Most of it focused on the fact that a relatively small and unknown company said it had built a chatbot that rivaled the performance of those from the world’s most famous AI companies, but using… Continue reading How Distillation Makes AI Models Smaller and Cheaper
