Elliptic Curve ‘Murmurations’ Found With AI Take Flight

Almost immediately, the preprint garnered interest, particularly from Andrew Sutherland, a research scientist at MIT who is one of the managing editors of the LMFDB. Sutherland realized that 3 million elliptic curves weren’t enough for his purposes. He wanted to look at much larger conductor ranges to see how robust the murmurations were. He pulled… Continue reading Elliptic Curve ‘Murmurations’ Found With AI Take Flight

Cellular Self-Destruction May Be Ancient. But Why?

The genes for apoptosis reminded Kaczanowski and Zielenkiewicz of an arms race between a predator and its prey. In their new paper, they speculated that they might be holdovers from the tools evolved by a prey organism, presumably the original mitochondrial bacterium, to defend itself. Maybe, once caught inside our ancient ancestor, apoptotic proteins became… Continue reading Cellular Self-Destruction May Be Ancient. But Why?

The Science behind Humpback Whales’ Eerie Songs

Devin Farmiloe: Those are the haunting melodies of baleen whales reverberating through the ocean waves. Many people across the globe are familiar with the 1970 album Songs of the Humpback Whale, produced by biologist Roger Payne. While I am a little too young to have caught its release, I remember seeing the CD for sale… Continue reading The Science behind Humpback Whales’ Eerie Songs

A Wild Claim about the Powers of Pi Creates a Transcendental Mystery

Pi (π) is probably the most famous number in mathematics. Not only have experts studied it extensively, but it also fascinates amateurs: books, films and songs have been dedicated to the number. Part of its appeal may be that even though it describes the circle, one of the simplest and most symmetrical geometric objects, it… Continue reading A Wild Claim about the Powers of Pi Creates a Transcendental Mystery

Groundwater Is Declining Globally, but There Are Hopeful Exceptions

New Breakthrough Brings Matrix Multiplication Closer to Ideal

That’s where Strassen’s laser method finally comes into play. “The laser method typically works very well and generally finds a good way to kill a subset of blocks to remove the overlap,” Le Gall said. After the laser has eliminated, or “burned away,” all the overlaps, you can construct the final product matrix, C. Putting… Continue reading New Breakthrough Brings Matrix Multiplication Closer to Ideal

Tiny Tweaks to Neurons Can Rewire Animal Motion

It was as if this ion channel were a dial that could twist one neuron type into the other. But what was actually different about this protein in the snake’s body and rattle? At first, the researchers thought that rattle motor neurons must have extra KV72/3 potassium channels. If the rattle neurons had more channels,… Continue reading Tiny Tweaks to Neurons Can Rewire Animal Motion

A Multitalented Scientist Seeks the Origins of Multicellularity

You did your postdoc with the zoologist Michael Akam at Cambridge. In an era when biochemistry predominates, the study of whole animals can sometimes seem like a throwback to another century. Why did you choose it? Because I wanted to take the findings in my dissertation to the next step. The dissertation examined how germ… Continue reading A Multitalented Scientist Seeks the Origins of Multicellularity

A New Agenda for Low-Dimensional Topology

Kirby has historically been a skeptic of the existence of structural biases in mathematics, including regarding the field’s gender imbalance. In the 1970s, about 10% of mathematicians were women; today almost 30% are, according to a 2020 report by the International Science Council. In an article that he wrote in the 1990s, and which was… Continue reading A New Agenda for Low-Dimensional Topology

The Opioid Crisis Is Now Being Tracked with Wastewater

Wastewater-based epidemiology, the process of monitoring health indicators through sewage, has become a common way to track the spread of SARS-CoV-2, the virus that causes COVID. But before 2020 scientists were using the technology to follow a different public health threat: the opioid crisis. Just as sewage data can fill gaps in SARS-CoV-2 tracking, this… Continue reading The Opioid Crisis Is Now Being Tracked with Wastewater
