The Case Against Dark Matter
...the dark matter hypothesis have some explaining of their own to do when it comes to McGaugh and his colleagues’ recent findings about the universal relationship between galaxy rotation speeds...
Physicists Uncover Geometric ‘Theory Space’
...languished for decades at the bottom of the physics toolkit. But recently the field has been re-energized as physicists have discovered novel bootstrap techniques that appear to solve many problems....
Inside the Knotty World of ‘Anyon’ Particles
...discovery. Such an important concept deserves a worthy grounding. What is quantum statistics, at bottom? The modern answer to that question is deep, beautiful and surprisingly recent. It emerged in...
How to Use a Sphere to Talk to Mars
...new story, “A New Path to Equal-Angle Lines.” There I describe a recent breakthrough in the study of what are called “equiangular lines.” A set of lines is considered equiangular...
A Simple Visual Proof of a Powerful Idea
Ramsey’s theorem predicts a surprising (and useful) consistency in the organization of graphs. Here’s a simple visual proof of how it works. A recent advance in geometry makes heavy use...
Swirling Bacteria Linked to the Physics of Phase Transitions
...of bacteria researchers of all stripes, and it has become almost de rigueur to suggest connections between active-matter experiments and biofilms. In their recent Nature paper, for example, Chaté and...
Discoveries Fuel Fight Over Universe’s First Light
...Hubble Space Telescope to spot extremely faint galaxies from as far back as 600 million years after the Big Bang — right in the thick of reionization. In a recent...
The Mathematics of Juggling
Juggling has advanced enormously in recent decades, thanks in part to the mathematical study of possible patterns. The late computer scientist Claude Shannon has a well-deserved reputation as the father...
Awash in Sea of Data, Ecologists Turn to Open Access Tools
...the update. Reproducibility has become a hot-button topic for the biomedical sciences and psychology in recent years, but those fields aren’t alone. Environmental scientists have warned repeatedly that problems with...
