Researchers from McGill University, led by Professor Alanna Watt of the Department of Biology, have identified previously unknown changes in brain cells affected by a neurological disease. Their...
Evolutionary biologists have long suspected that the diversification of a single species into multiple descendent species – that is, an “adaptive radiation” – is the result of each species adapting...
Insect populations are widely influenced by weather anomalies, with decreasing numbers observed during unfavorable conditions and a spike in normal periods, according to a new study. The study...
Spinal cerebellar ataxia 6 (SCA6) is an inherited neurological condition which has a debilitating impact on motor coordination. Affecting around 1 in 100,000 people, the rarity of SCA6 has seen it...
Many mammal species living in cold climates tend to have large bodies and short limbs to reduce heat loss – a general pattern known as Bergmann’s rule. However, bats are the exception to the rule,...
Wild populations must continuously adapt to environmental changes or risk extinction. For more than fifty years, scientists have described instances of “rapid evolution” in specific populations as...
In humans, the dopamine system has been tied to rewards and pleasurable sensations. As well as to memory and learning. A recent study from McGill University, published in Current Biology, suggests...
