On Twitter this week I joked that neuroscientists could save money on brain scanners by just asking people how active their brains are.
Why do we spend so much on neuroimaging and then rely on self-report measures of the other variables of interest? Why not self-report brain activity, how active is your amygdala 1-10? https://t.co/ph3A2Uc6zc— Neuroskeptic (@Neuro_Skeptic) November 6, 2019
However, it turns out that there has already been a study that actually asked people to do ...read more

Taking control of a 3,000-pound rocket motor launching into an inhospitable environment at speeds exceeding 2,000 mph sounds terrifying to some. But others will spend their whole careers in pursuit of those ephemeral, weightless moments.
With the expansion of commercial space exploration, more pilots will be needed to guide spacecraft beyond the bounds of Earth. These pilots com ...read more

Reluctant joggers, here’s some encouragement: Running even once a week has some benefits.
According to a new study, running 50 minutes a week, at a pace between a 10- and 7.5-minute mile, helped reduce the risk of death from cancer, cardiovascular disease and other causes. Working out more than that didn’t convey significantly more health benefits, say the researchers, base ...read more

Over the past couple of decades, astronomers have discovered thousands of alien planets and solar systems. These worlds come in a wide variety of arrangements, many of which are quite different from what we see in our own solar system.
Some have giant planets that swing through the planetary systems in stretched-out, or “eccentric,” elliptical orbits, unlike the nearly circular orbits of planets like Jupiter and Saturn.
Astronomers think that many ...read more

A new collection of DNA from ancient Romans spanning 12,000 years shows how the population of the empire’s capital shifted along with its politics. Published in Science, the timeline is one of the first to examine what genetic information from archaeological digs says about the region after the time of hunter-gatherers and early farmers.
The analysis found that ancient Romans were from all over Europe, the Near East and northern Africa. “Rome was a ...read more
