Having lots of mitochondria is normally risky for cells because their chemical activity generates toxic byproducts known as free radicals. But when Böke peered inside dormant human and frog oocytes, they weren’t overloaded with free radicals at all. As she reported in a Nature paper published in 2022, the oocytes’ mitochondria were doing something surprising:… Continue reading How ‘Idle’ Egg Cells Defend Their DNA From Damage
Strangely Curved Shapes Break 50-Year-Old Geometry Conjecture
In an old Indian parable, six blind men each touch a different part of an elephant. They disagree about what the elephant must look like: Is it smooth or rough? Is it like a snake (so thinks the man touching the trunk) or a fan (as the man touching the ear proposes)? If the blind… Continue reading Strangely Curved Shapes Break 50-Year-Old Geometry Conjecture
Inflation Isn’t a Bug in the System, It’s a Feature
May brings more bad economic news for hard-pressed American households. “Transitory” inflation remains firmly entrenched at rates equal to or higher than those reported at the start of 2024. The Labor Department reports this week that the Consumer Price Index, or CPI, it’s official measure of the rate of change in the retail price of a… Continue reading Inflation Isn’t a Bug in the System, It’s a Feature
Vaccine-resistant Mothers Blame Bad Experiences in Health Care
The following essay is reprinted with permission from The Conversation, an online publication covering the latest research. Why would a mother reject safe, potentially lifesaving vaccines for her child? Popular writing on vaccine skepticism often denigrates white and middle-class mothers who reject some or all recommended vaccines as hysterical, misinformed, zealous or ignorant. Mainstream media… Continue reading Vaccine-resistant Mothers Blame Bad Experiences in Health Care

Computer Scientists Invent an Efficient New Way to Count
Let’s return to Hamlet, but this time your working memory — consisting of a whiteboard — has room for just 100 words. Once the play starts, you write down the first 100 words you hear, again skipping any repeats. When the space is full, press pause and flip a coin for each word. Heads, and… Continue reading Computer Scientists Invent an Efficient New Way to Count
Scientists Find a Fast Way to Describe Quantum Systems
The new result is the fruit of several years’ worth of scientific labor. Prior research by Anshu and others got part of the way there. Those researchers developed an algorithm that could deduce a system’s Hamiltonian using a reasonable amount of sample data: The amount needed increased only as a polynomial function of the number… Continue reading Scientists Find a Fast Way to Describe Quantum Systems
Should You Believe Faulty U.S. Crime Stats or Your Own Lying Eyes? It’s a Tough Call
Car theft, above, might be a better barometer of the state of crime than other measures. Unlike other crimes, they tend to be logged accurately — and have risen markedly. By James Varney, RealClearInvestigationsMay 14, 2024 Americans can be forgiven for suffering from whiplash regarding law and order. In recent weeks the Biden administration and… Continue reading Should You Believe Faulty U.S. Crime Stats or Your Own Lying Eyes? It’s a Tough Call
How Do Chemicals in Plastics Impact Your Endocrine System?
The translucent exterior of a plastic soda bottle hides a secret in plain sight: hundreds of synthetic chemicals embedded in its seemingly innocuous material. These chemicals give the plastic its structure, flexibility and durability, among other qualities—the same traits that also make plastic last for centuries, causing it to accumulate and endure in nature. Before… Continue reading How Do Chemicals in Plastics Impact Your Endocrine System?
