Engineer Aaron Lindenberg is an expert in the ways atoms and electrons move through materials. He uses X-ray “flash photography” to make movies of atoms moving at ultrafast speeds to predict the fundamental limits of electronics in future consumer devices, solar cells, and AI chips. He estimates we are “many orders of magnitude away” from the physical limits of both speed and energy efficiency in our electronics. Today’s computers are at least a thousand times slower than they could be, Lindenbe...

Computer scientist Keith Winstein is an expert in how computers communicate. Computer networks create what he calls shared fictions – abstract realities, like a website or a Zoom call, that exist only because the computers on either end agree to act as if they are real. Unfortunately, today’s networks lack a shared notion of a “computation,” which hurts market efficiency in cloud computing and frustrates efforts to hold tech companies accountable for the results of their algorithms. As computati...

Legal expert Richard Ford studies the intersection of dress codes and the law. Clothing and hairstyles communicate power, identity, and social status, he says. Legal restrictions on dress stretch at least to the Middle Ages when “sumptuary laws” stipulated what one could wear by rank. Today, written rules have given way to unwritten codes that are in many ways more powerful culturally. Fashion is not trivial, he says, and no less worthy of study than high art or music. Clothing shapes everything...

Epidemiologist Yvonne “Bonnie” Maldonado is an expert in vaccine research and public health. Look back centuries, and the story is always the same, she says: Death rates from viruses have plummeted, especially in children and the elderly. And yet, millions of children die each year from vaccine-preventable diseases. Vaccines need a return of public confidence, and that starts with better messaging and greater support of nongovernmental messengers like herself. The bottom line is that vaccines ar...

Physician-scientist Randall Stafford studies the effects of alcohol use on population health – the true health impact, he emphasizes. Stafford explains how early research suggested that drinking is beneficial – or at least not bad – for people. That mindset produced decades of wishful thinking based on inconsistent science driven by social, emotional, and industry forces. The small cardiovascular benefits, he says, are far outweighed by the risks of cancer, liver disease, depression, and other i...
