4:47 PM | Vehicle-to-grid technology: Electric cars become power-grid batteries.

Imagine a car that runs quietly, burns no gas, produces no emissions, stores renewable energy, and sometimes even pays you back. Seem like a pipe dream? Soon it won’t be. Vehicle-to-grid technology allows networks of electric vehicles (EVs) to function like a giant battery with an intelligent software interface feeding power from car to grid [...]

Scanning a brain that believes it is dead

What is going on in the brain of someone who has the deluded belief that they are brain dead? A team of researchers led by neuropsychologist Vanessa Charland-Varville at CHU Sart-Tilman Hospital and the University of Liege has attempted to find out by scanning the brain of a depressed patient who held this very belief. The researchers used a Positron Emission Tomography (PET) scanner, which is the first time this scanning technology has been used on a patient with this kind of delusion […]

How Your Social Status Influences the Way You’re Judged

One of the palpable weaknesses in the American justice system is the tendency for it to produce different outcomes for people from different social classes. Part of this is a result of discrepancies in the quality of legal representation people can afford, but part of it is also due to inconsistencies in the way morally questionable activities [...]

“You’ll Do”: Lack of Choosiness in Female Strawberry Poison Dart Frogs

Mate choice is one of the most well-studied aspects of evolution. To prove that they’re worth the effort, animals will do just about anything. They dance, prance, sing, bellow, and fight for attention. When you look around the animal kingdom, the wild results of mate choice boldly stand out, from the impractically beautiful tails of [...]

The Valentine's Day Magnetic Monopole

There's an assymetry to the form of the two Maxwell's equations shown in picture 1. While the divergence of the electric field is proportional to the electric charge density at a given point, the divergence of the magnetic field is equal to zero. This is typically explained in the following way. While we know that electrons, the fundamental electric charge carriers exist, evidence seems to indicate that magnetic monopoles, the particles that would carry […]

Why don't men understand women?

Men might have found themselves an excuse not to listen to women. New research suggests that men have twice more difficulty reading emotions in women than in men. This may not sound surprising, but evidence that men have trouble understanding women is, at best, scarce.Being able to guess someone else’s thoughts, feelings and intentions is […]
