The new result is the fruit of several years’ worth of scientific labor. Prior research by Anshu and others got part of the way there. Those researchers developed an algorithm that could deduce a system’s Hamiltonian using a reasonable amount of sample data: The amount needed increased only as a polynomial function of the number… Continue reading Scientists Find a Fast Way to Describe Quantum Systems
Should You Believe Faulty U.S. Crime Stats or Your Own Lying Eyes? It’s a Tough Call
Car theft, above, might be a better barometer of the state of crime than other measures. Unlike other crimes, they tend to be logged accurately — and have risen markedly.

How Do Chemicals in Plastics Impact Your Endocrine System?
The translucent exterior of a plastic soda bottle hides a secret in plain sight: hundreds of synthetic chemicals embedded in its seemingly innocuous material. These chemicals give the plastic its structure, flexibility and durability, among other qualities—the same traits that also make plastic last for centuries, causing it to accumulate and endure in nature. Before… Continue reading How Do Chemicals in Plastics Impact Your Endocrine System?
The Mystery of the Missing Multicellular Prokaryotes
The genomes of prokaryotes, however, tend to collapse in size in the face of genetic drift, as suggested by work done by Howard Ochman of the University of Texas, Austin and Louis-Marie Bobay, now at North Carolina State University. It’s not clear why, but it may be because gene regulation in prokaryotes is much less… Continue reading The Mystery of the Missing Multicellular Prokaryotes

Dogged Dark Matter Hunters Find New Hiding Places to Check
If or when SLAC’s planned project, the Light Dark Matter Experiment (LDMX), receives funding — a decision from the Department of Energy is expected in the next year or so — it will scan for light dark matter. The experiment is designed to accelerate electrons toward a target made of tungsten in End Station A.… Continue reading Dogged Dark Matter Hunters Find New Hiding Places to Check
