Why, after millions of years of evolution, do organisms build structures that seemingly serve no purpose?
I love ecology. I can geek out all day on patterns in nature: ecosystem services, food webs, eco-evolutionary dynamics, nutrient cycles, range shifts.
Researchers at Disney Research, Zürich, ETH Zürich, and Cornell University have invented a system to digitize facial hair and skin. Capturing facial skin and geometry is a fundamental technology for a variety of computer-based special effects for movies.
With whole genome sequencing quickly becoming more affordable and accessible, we need to pay more attention to the massive amount of information it will deliver to parents ? and the fact that we don't yet understand what most of it means, concludes an article in the
Singing mice (Scotinomys teguina) are not your average lab rats. Their fur is tawny brown instead of the common white albino strain; they hail from the tropical cloud forests in the mountains of Costa Rica; and, as their name hints, they use song to communicate.

“A 24-year-old unmarried male software professional, not a known case of diabetes or hypertension, presented with episodes of severe, exploding holocranial headache on watching pornographic videos for the last 2 years. The headache would develop gradually over 5 min of viewing videos and would peak within 8?10 min. The intensity was so severe that he had to abort watching. There was no accompanying nausea, vomiting, or phonophobia. Progressively, he started to refrain from viewing videos as a means of avoiding headaches. There was no history of headache associated either with masturbation or with coitus. He had no history of head injury or meningoencephalitis in early childhood. There was no history suggestive of migraine in the family. He did not have a history suggestive of migraine, tension type or exertional headache. A physical and systemic examination was unremarkable. The neurological examination was normal. Magnetic Resonance (MR) Imaging, MR angiography of brain, and electroencephalogram were normal. He was advised non-steroidal anti-inflammatory agent combination (ibuprofen 400 mg and paracetamol 500 mg) half an hour before watching, to which he reported significant pain relief.
Headaches associated with sexual activity are uncommon (Anand & Dhikav, 2009). ...

I remember once, a long time ago, wondering what a photon would look like if I could freeze one, or better yet, if I could catch up to one and travel with it. I also recall being completely flummoxed by the question and the answers my professors gave me (when they didn't roll their eyes and kick me out of their offices.)
