Determination might be a very human expression March 6, 2014
Humans might be using facial expressions of determination as a call for help from others, according to new research.When children and chimpanzees were both given a task that was impossible to solve, children's faces expressed determination or frustration the more they tried to solve the task, but chimpanzees did not.
New molecules doom proteins with kiss of death March 6, 2014
Like mobsters following strict orders, newly engineered molecules called "ubiquibodies" can mark specific proteins inside a cell for destruction - a molecular kiss of death that is paving the way for new drug therapies and powerful research tools.
Motion-sensing cells in the eye let the brain 'know' about directional changes March 5, 2014
How do we "know" from the movements of speeding car in our field of view if it's coming straight toward us or more likely to move to the right or left?Scientists have long known that our perceptions of the outside world are processed in our cortex, the six-layered structure in the outer part of our brains. But how much of that processing actually happens in cortex?
Understanding PP1, the ubiquitous enzyme March 5, 2014
The enzyme PP1 has a key role in many of the body's healthy functions and diseases. It's so generally important that drug developers dare not target it. In a new study in the Proceedings of the National Academy of Sciences, Brown University scientists report a big leap in understanding how PP1 interacts with other proteins to behave specifically in distinct situations.
Homing in on cancer with a comprehensive measurement method March 4, 2014
Cancer is the second most common cause of death in Switzerland. There are many reasons why in the era of cutting-edge medicine it is still difficult to cure this disease. A tumour may, for instance, consist of different tumour cell subpopulations, each of which has its own profile and responds differently to therapy - or not.
