4:33 PM | Fairness May Be Built Into The Brain - But Fairness Doesn't Mean Equal Income
Is fairness built into the brain? According to a new Norwegian brain paper, people appreciate fairness - but fairness is not that everybody gets the same income, which is sure to concern those who believe all money should be distributed equally. Economists from the Norwegian School of Economics and brain researchers from the University of Bergen decided to try and assess the relationship between fairness, equality, work and money: how brains react to how income is distributed. The team looked […]

4:30 PM | Laser physicists from Australia have built a reversible tractor beam capable of retrieving tiny part
Laser physicists from Australia have built a reversible tractor beam capable of retrieving tiny particles. It's nowhere near as strong as the beams portrayed in scifi, but it's the first long-distance optical tractor beam capable of moving particles one fifth of a millimeter in diameter a distance of up to 20cm. Scaled up, it could eventually be used to control atmospheric pollution. Read more...

currentsinbiology: These Bacteria Are Wired to Hunt Like a Tiny Wolf Pack There is an elaborate stealth communication network in the Earth beneath your feet. This smart web acts like a superorganism, fortifying defensive capabilities and coordinating deadly attacks on unsuspecting targets. But it’s not run by the NSA, the CIA, or the military. This web is made of bacteria. A team of scientists led by Manfred Auer at Lawrence Berkeley National Laboratory have used cutting-edge 3-D […]

4:08 PM | The Editor's Letter From The November 2014 Issue Of Popular Science
Cliff Ransom, Editor In Chief Of Popular Science Marius Bugge About a year ago, Popular Science introduced a robot into the office. One of the many virtues of working at a magazine such as ours is that we’re free to test all sorts of cool stuff. So we called the guys at Suitable Technologies and asked them to send us a BeamPro, the telepresence robot made famous by Edward Snowden (no doubt, he got the idea from us). At the outset, we thought working side by side with a […]

NEW VIDEO! How To See Time Travel In this week’s It’s Okay To Be Smart, I’ll show you how to build your own cosmic particle detector and witness time travel with your very own eyes! Earth is under constant bombardment from cosmic radiation. There’s sunlight, of course, but that’s the good stuff. Solar wind, the next most common variety, is mostly blocked by Earth’s magnetic field and diverted to the poles. But there are other, more distant sources of charged […]

3:54 PM | Belly Button Portraits – An Opportunity to Create Art through Science!
We’d like to think that over the course of the last few years, our Belly Button Biodiversity project has inspired quite a few things. We’re confident it inspired participants and the millions around the world who heard about the project to think differently, perhaps appreciatively, about their skin microbes, even those inhabiting this funny little spot on your abdomen. We’re thrilled it inspired educators from middle school to college to bring Belly Button Biodiversity into […]

3:45 PM | Brain activity provides evidence for internal 'calorie counter'
As you glance over a menu or peruse the shelves in a supermarket, you may be thinking about how each food will taste and whether it's nutritious, or you may be trying to decide what you're in the mood for. A new neuroimaging study suggests that while you're thinking all these things, an internal calorie counter of sorts is also evaluating each food based on its caloric density. The findings are published in Psychological Science, a journal of the Association for Psychological […]
