It is Valentine’s Day and I want to talk to you about how you smell. This will not be a discussion about how your musky, earthy scent attracts a mate. No, we need to have a conversation about how your urinous, acidic odor might drive one away. There are ways to safeguard against the Valentine’s [...]

Imagine the challenge of developing a chemical monitor to implant beneath the skin. The technology would provide non-invasive, constant monitoring of glucose in diabetic patients instead of current sporadic measurements requiring blood withdrawal. But its development is a rubix cube—all aspects of the puzzle must be considered with every turn; focus on one face and the other five will be a mess.

8:00 AM | The Amazing Adventures of Spider Silk

Spidey’s secret identity is being revealed, and it has nothing to do with Peter Parker. Chemists and biochemists are manipulating spider silk in ways that a few years ago would have been possible only in a comic book.

8:00 AM | Fat Tuesday: Why Chocolate Tastes So Good

For those of you who will be enjoying Easter candy this weekend (or just the discounted crème eggs next week), guest blogger and former chemistry prof Rebecca Guenard of Atomic-o-licious explains the inescapable power of chocolate.

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 […]
