The reference frames from which observers view quantum events can themselves have multiple possible locations at once — an insight with potentially major ramifications. The post In the Quantum World, Even Points of View Are Uncertain first appeared on Quanta Magazine

We often consider spoken language to be a feature that distinguishes humans from other forms of animal life. Brain research, however, suggests that other creatures — including certain birds — share some of our neural circuitry related to language. In this episode, co-host Janna Levin explores the origins and underlying mechanisms of human speech and birdsong with neurobiologist and geneticist Erich Jarvis. The post...

Two mathematicians have renewed a debate about the fundamental nature of some of math’s most important equations. The post New Elliptic Curve Breaks 18-Year-Old Record first appeared on Quanta Magazine

How do we know if a large language model is lying? Letting AI systems argue with each other may help expose the truth. The post Debate May Help AI Models Converge on Truth first appeared on Quanta Magazine

With lots of data, a strong model and statistical thinking, scientists can make predictions about all sorts of complex phenomena. Today, this practice is evolving to harness the power of machine learning and massive datasets. In this episode, co-host Steven Strogatz speaks with statistician Emmanuel Candès about black boxes, uncertainty and the power of inductive reasoning. The post How Is AI Changing the Science...

Yizhi “Patrick” Cai is coordinating a global effort to write a complete synthetic yeast genome. If he succeeds, the resulting cell will be the artificial life most closely related to humans to date. The post He’s Gleaning the Design Rules of Life to Re-Create It first appeared on Quanta Magazine

It was intuitive, even obvious. It was also wrong. The post Math’s ‘Bunkbed Conjecture’ Has Been Debunked first appeared on Quanta Magazine

A new experimental proposal suggests detecting a particle of gravity is far easier than anyone imagined. Now physicists are debating what it would really prove. The post It Might Be Possible to Detect Gravitons After All first appeared on Quanta Magazine

All modern multicellular life — all life that any of us regularly see — is made of cells with a knack for compartmentalization. Recent discoveries are revealing how the first eukaryote got its start. The post Meet the Eukaryote, the First Cell to Get Organized first appeared on Quanta Magazine

The idea of a species is fundamental to the way that many people understand the structure of life on Earth. But ask 10 specialists how they define the concept and you might get 10 answers. In this episode, co-host Janna Levin speaks with evolutionary biologist Kevin de Queiroz about what makes defining and delineating species such a slippery process, and why it matters to...

The giant holes in galaxies’ centers shouldn’t be able to merge, yet merge they do. Scientists suggest that an unusual form of dark matter may be the solution. The post How Do Merging Supermassive Black Holes Pass the Final Parsec? first appeared on Quanta Magazine
