New Math Revives Geometry’s Oldest Problems
But the methods were no longer effective when mathematicians only wanted to find, say, the number of real solutions to the equations in an enumerative geometry problem, or the number of integer solutions. If they asked an enumerative geometry problem in any number system other than the complex one, inconsistencies cropped up again. In these… Continue reading New Math Revives Geometry’s Oldest Problems
The Return of Economic Statecraft
The “Liberation Day” tariffs that US President Donald Trump announced on April 2 did not resurrect economic statecraft. It never went away. The new US approach, however, signaled a decisive shift. Until then, the European Union had preferred to convince itself that each episode of economic statecraft could be managed without asking hard questions regarding… Continue reading The Return of Economic Statecraft

September 18, 2025 3 min read Genetics Can Track How Languages Mixed in the Past New research shows that wherever human populations mix, their languages blend as well By Cody Cottier edited by Allison Parshall PhotoHamster/Getty Images When speakers of different languages meet, their words, sounds and even grammatical structures mingle in surprising ways. Ketchup,… Continue reading Languages Have Mixed through History. Our Genes Can Reveal How
AI Is About to Change Our Lives Forever. Luckily We Have a User Manual for That.
You probably haven’t thought about philosophers John Locke or Thomas Hobbes since high school, or that required college class. They died centuries before personal computing was invented, let alone the artificial intelligence technologies that now infuse many parts of our daily life. What could they possibly teach Americans about living in a world with AI?… Continue reading AI Is About to Change Our Lives Forever. Luckily We Have a User Manual for That.
How the Brain Balances Excitation and Inhibition
Inhibitory neurons have “often been ascribed support roles,” said Annabelle Singer, a neuroscientist and neuroengineer at the Georgia Institute of Technology and Emory University. That’s likely because it’s simply easier to study excitatory neurons. For example, an excitatory place cell in the hippocampus can fire when an animal is in a particular location. When this… Continue reading How the Brain Balances Excitation and Inhibition
AI Won’t Outrun Bad Procurement
Artificial intelligence is widely recognized as a linchpin of modernization. Yet, as federal agencies increasingly look to integrate AI into their operations, the stumbling blocks are not technological. It’s failures in procurement practices that, if not avoided, undermine the potential of AI. Two high-profile government automation projects offer cautionary tales. Each reveal how even well-funded… Continue reading AI Won’t Outrun Bad Procurement
A Simple Way To Measure Knots Has Come Unraveled
The duo kept their program running in the background for over a decade. During that time, a couple of computers from their ragtag collection succumbed to overheating and even flames. “There was one that actually sent out sparks,” Brittenham said. “That was kind of fun.” (Those machines, he added, were “honorably retired.”) Then, in the… Continue reading A Simple Way To Measure Knots Has Come Unraveled
Requiem for a Visa
U.S. government data (PDF) show that in 2023 a newly approved H-1B visa worker with the most common qualification—a bachelor’s degree in computer science or engineering—earned a median salary of $99,000. By contrast, the cost of securing that visa was already high. The application fees in 2024 were between $3,500 and $6,000, and once lawyers… Continue reading Requiem for a Visa
