Internet usage: how much is too much?

Reuters reports that one in eight American adults believe they need to cut back their internet usage. The study cited is based on phone interviews of more than 2500 people conducted in 2004 and will appear in the October issue of CNS Spectrums: The International Journal of Neuropsychiatric Medicine. Naturally, even though the headline is […]

How Genes Have Harnessed Physics to Grow Living Things

The same pulling force that causes “tears” in a glass of wine also shapes embryos. It’s another example of how genes exploit mechanical forces for growth and development.

A Gene-Editing Therapy Cut Cholesterol Levels by Half

An experimental gene-editing therapy developed by Crispr Therapeutics is showing promise for treating heart disease.

A New Startup Wants to Edit Human Embryos

Seven years after the first gene-edited babies were revealed, biotech startup Manhattan Genomics is reviving the idea of editing human embryos to make disease-free children.

Hurricane Melissa Has Meteorologists Terrified

The storm, which is set to make landfall in Jamaica on Tuesday, has stunned meteorologists with its intensity and the speed at which it built.

Physicists Create a Thermometer for Measuring ‘Quantumness’

“Anomalous” heat flow, which at first appears to violate the second law of thermodynamics, gives physicists a way to detect quantum entanglement without destroying it.

Man Has Pig Kidney Removed After Living With It for a Record 9 Months

With the demand for human donor organs desperately outstripping supply, scientists are working to see if genetically edited pig organs can bridge the gap.

Unpicking How to Measure the Complexity of Knots

Two mathematicians have proved that a straightforward question—how hard is it to untie a knot?—has a complicated answer.

The ‘10 Martini’ Proof Connects Quantum Mechanics With Infinitely Intricate Mathematical Structures

The proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, uses number theory to explain quantum fractals.

An Invasive Disease-Carrying Mosquito Has Spread to the Rocky Mountains

The Aedes aegypti mosquito that can carry dengue, yellow fever, and Zika was thought to be too reliant on a hot and wet climate to survive in the Mountain West. But now, a population is thriving in Western Colorado.

The Hidden Math of Ocean Waves

The math behind even the simplest ocean waves is notoriously uncooperative. A team of Italian mathematicians has made major advances toward understanding it.

The Physics of the Northern Lights

Solar winds at a million miles an hour and freaky magnetic turbulence are sparking some of the best light shows in centuries.

Climate Change Made Hurricane Melissa 4 Times More Likely, Study Suggests

Unusually warm ocean temperatures fueled one of the worst hurricanes on record. New research finds climate change increased the storm’s likelihood.
