The human ability to infer what other people are thinking is a big reason we’re able to understand and cooperate with others. Along with the ability to take pictures of our food, it’s what separates us from lesser primates. But we’re not born with this ability. Experiments involving what’s called the “change-of-location” or “false-belief” task show [...]... Read more »

When we typically think of how decision-making works in the brain, we think of new input coming in, perhaps through the eyes or ears, being processed in the relevant sensory areas, and then sent to the ‘decision-making’ areas (the basal ganglia, prefrontal cortex, or anterior cingulate cortex) where this information is used to make a decision. [...]... Read more »

There’s been a lot of talk about “paleo diets”, but here we have the real deal. A meal caught in the middle of digestion in a dinosaur.
Microraptor gui was introduced back in 2003, and immediately attracted attention because of the its feathers, particularly lots of long, prominent feathers on its hind legs, so unlike any bird or other flying beast we know of. There is good evidence (though disputed) that it was a glossy, black animal, rather like the grackles that hang around my campus.

Brain white matter plays a key role in connecting functional brain areas. These connections are required for complex brain processing required for memory and executive functions, i.e planning and problem solving.Diffusion tensor imaging (DTI) is a relatively recent brain imaging tool that provides a method of analyzing regional human white matter function. Additionally, when DTI is paired with cognitive testing it allows for study of the brain regions and circuits responsible for spe........ Read more »

In archaeology, we are constantly getting updates on old material. When results are released, it isn’t always when the study itself is complete. Further, new methods or techniques may lead to re-analysis of older sites and remains, revealing new conclusions.

Surprisingly little is known about where people seek advice when their dog has a behavioural problem such as aggression, soiling in the house, or fear of fireworks.

Plants are great poison generators. Their toxins can affect skin, heart function, nerve function, or muscle function. In many cases plants make more than one toxin. The manchineel tree for instance, can induce everything from blindness to blisters to swelling of larynx. Oleander is toxic, but for different reasons, and urushiol from poison ivy induces a type IV hypersensitivity. Sounds like none of this is good for humans, but new research studies are showing medicinal values for these plant tox........ Read more »

Research has demonstrated that experiencing head or neck trauma or minor acute infections such as influenza can increase risk for stroke among adults. Inflammation in the CNS or in the periphery may be a risk factor for the initial development of cerebral ischemia. Fullerton (University of California, San Francisco, USA) and colleagues hypothesized that trauma and acute infections are independently associated with childhood arterial ischemic stroke (AIS). Researchers carried out a case........ Read more »

Take Home Message: Coaches who are well trained to implement injury prevention, warm-up programs are as effective as the supervision of a physiotherapist at training sessions.

While many programs exist it is difficult to assess their efficacy due to varying levels of adherence to the injury prevention program. Therefore, Steffen and colleagues completed a cluster-randomized trial t........ Read more »
