Your brain might just be killing you slowly. Atherosclerosis — or hardening and narrowing of the arteries — can be caused by fat buildup that causes plaque deposits, and is one of the main causes of cardiovascular disease. What does that have to do with the brain? Well new research has shown a link between how the brain regulates fat metabolism, which has the potential of stopping the development of this disease risk factor in obesity and diabetes....

Left or right? Apple or orange? Selma or Birdman? One way to make these decisions is precisely what intuition tell us it should be: we weigh up the pros and cons of each choice. Then, when we have sufficient evidence for one over the … Continue reading →... Read more »

Athletes don't normally need to be chased down the track to get their training mileage in. But a green anole lizard is not a normal athlete.
Scientists wanted to know whether it's possible to train a lizard at all. Human athletes and other mammals perform better with consistent exercise, but is this universal? Can a reptile increase its stamina? What about its sprint speed? So the scientists became lizard athletic trainers, which really means lizard harassers. Results were mixed.
The g... Read more »

Star Trek celebrates its 50th anniversary in 2016. In preparation for the celebrations, we’re checking in on how close we are to making Star Trek technology a reality. The replicator made food and recycled trash, and later was used to make parts for the Enterprise. A machine fabricated what they needed on the spot. We have that now on the space station! Do you know how 3-D printing works and how we print parts, food, and even living tissue? Here’s how.... Read more »

The paper by Ryan Yuen and colleagues  suggesting that most siblings with autism do not share the same genetic variations thought to contribute to the condition has garnered quite a few media headlines of late (see here and see here).Applying the concept of whole-genome sequencing whereby the complete genetic blueprint of a person is mapped to provide "the most comprehensive collection of an individual's genetic variation" , 340 genomes from 85 families with two children with a d........
