These Clever Dogs Know the Difference between ‘Pull’ and ‘Throw’ Toys

September 18, 2025 2 min read Some Dogs Can Learn Categories like Human Toddlers Do These dogs can extend words to new objects based on function the way children do in early language learning By Anirban Mukhopadhyay edited by Sarah Lewin Frasier Researchers found that some dogs can learn terms for functional categories, such as… Continue reading These Clever Dogs Know the Difference between ‘Pull’ and ‘Throw’ Toys

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

Languages Have Mixed through History. Our Genes Can Reveal How

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

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

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

Tsunami Risk Waning A powerful magnitude 7.8 aftershock off Russia’s Kamchatka Peninsula that arose from July’s magnitude 8.8 earthquake is raising concerns about possible tsunami impacts, although risk appears to be waning By Meghan Bartels edited by Lee Billings A seismic map shows the epicenter… Continue reading Aftershock Rocks Kamchatka after July’s Massive Earthquake

‘Skibidi’ and ‘Brain Rot’ Are Part of Millennia-Old Patterns of Language Evolution

This episode was made possible by the support of Yakult and produced independently by Scientific American‘s board of editors. Rachel Feltman: For Scientific American’s Science Quickly, I’m Rachel Feltman. If you’ve ever heard a youth say “skibidi” and lamented the downfall of the English language, today’s episode might surprise you. Our guest is Adam Aleksic,… Continue reading ‘Skibidi’ and ‘Brain Rot’ Are Part of Millennia-Old Patterns of Language Evolution

To Understand AI, Watch How It Evolves

How so? In one recent paper, we used random variation between different training runs to find correlations between models’ internal structure and their generalization behavior. If structure and behavior are correlated across a bunch of random initializations when you control for everything else, it’s likely that they’re actually linked. You can make a much stronger… Continue reading To Understand AI, Watch How It Evolves
