No one expects the machinery of progress to roll backwards, but sometimes it seems that no one is watching the speedometer (or manning the brakes, assuming any exist). Is this a fair assessment? If so, should we be worried — and what can we do about it?
In this feature, experts on technology, risk, science, policy and neuroscience discuss risk, innovation and how our values affect our conceptions of both.
This year’s Consumer Electronics Show in Las Vegas brought another bumper crop of tech for geeks and gearheads alike.
As usual, this year’s show was more about evolution than revolution. That, and the proliferation of sensors in everything from hairbrushes to toothbrushes. But one technology was clearly the belle of the geek prom: Amazon’s digital assistant, Alexa.
An Arizona State University team has used a unique high-throughput screening system to complete the largest-ever analysis of microRNAs (miRNA), the puzzling little cousins of RNA that help regulate gene expression.
Their findings offer a new explanation for why groups of similar miRNA sequences, called miRNA families, are so plentiful in higher species of animals, including humans.
The book The Runner’s Brain told runners how their minds could change their running. Now a University of Arizona study says the reverse might be true as well.
Using functional connectivity MRI (fcMRI), they found significant differences in areas that are active when the brain is at rest. Possibly, such networks could play a key role in the effects of aging and neurodegenerative diseases.
