It’s no secret that carnivorous plants are just way cool. Yet despite all the attention, there is still a lot we don’t know about them. Recent studies have expanded the view we have of these plants so that we now recognize more and more of them – like tomatoes and potatoes. Yes, our vegetables are insectivores!

When animals live caves full time, their descendents often lose their eyes. It has happened over and over and over and over again, in all different kinds of animals. But how this happens is not obvious. Stephen Jay Gould wrote that some people would use cave fish as an argument that “Lamarck must have been on to something” with his idea that acquired characteristics can be inherited. Well, no, that’s not that case, but it is a good example of how tricky thinking about losses can be.

If you’ve seen March of the Penguins, you probably understand the question. Many penguins live a shitty life, walking miles and miles without any food and spending months apart from their families.

Take Home Message: High adherence to a neuromuscular injury prevention program like the FIFA 11 decreases the risk of injury.
Injury prevention programs typically are multifaceted warm-up programs that focus on neuromuscular recruitment. Although various programs aim to improve performance and decrease injury risk no investigation has shown a link between improved physical performance and the quality and adherence of neuromuscular injury prevention training. Therefore, Steffen and colleague........ Read more »

“LET THERE BE LIGHT!” said the microscopist. Light plays a crucial role in microscopy and cell biology, and a recent paper describes the use of light to understand protein secretion.Light is used in microscopy in countless ways—to illuminate a sample, excite a fluorophore, and signal the localization or dynamics of a protein. Light can also be used to manipulate cellular events through the use of “caged” compounds that become active after illumination by certain wavelengths........ Read more »

It’s time to stop scoffing at the synesthetes: linking music to colors is totally normal. It’s not really about the notes, though. Researchers say the colors we find in music are actually the colors of the emotions the music makes us feel.
Synesthetes are people whose sensory experiences overlap; they most often link letters or numbers to certain colors. Music-color synesthesia, in which hearing music triggers the colors, is rarer. In fact, when Stephen Palmer and Karen Schloss at the........ Read more »
Scientists at Oregon Health & Science University and the Oregon National Primate Research Center (ONPRC) have successfully reprogrammed human skin cells to become embryonic stem cells capable of transforming into any other cell type in the body. It is believed that stem cell therapies hold the promise of replacing cells damaged through injury or illness. Diseases or conditions that might be treated through stem cell therapy include Parkinson’s disease, multiple sclerosis, cardiac disease a........ Read more »

Negotiation training has been shown to lead to positive outcomes for parties on both sides of the table, identifying 'win-win' solutions and helping the wheels of the world turn more amicably. But many studies focus on consequences when both negotiators are trained using the same methodology, when the reality is that a counterpart from another organisation may be trained differently or not at all. What happens then? A study by Alfred Zerres and colleagues finds out.The study recruited 360 busine........ Read more »

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 -........ Read more »
