11:50 AM | Watching a paradigm shift in neuroscience
When I finished my PhD 15 years ago, the neurosciences defined the main function of brains in terms of processing input to compute output: “brain function is ultimately best understood in terms of input/output transformations and how they are produced” […] ↓ Read the rest of this entry...

7:07 PM | The Rise of Evolutionary Biology Can Be Attributed To … A Harry Potter Character?
As mentioned in my previous post, the Modern Synthesis of evolutionary biology during the 1930s and 1940s was the result of combining different fields, such as systematics, genetics and paleontology. The genetic piece of the evo-puzzle was put in place by Theodosius Dobzhansky, who wrote the influential Genetics and the Origin of Species in 1937. He is […]

On the left is Geosesarma dennerle, on the right G. hagen. Both have yellow eyes, hence "vampire" crabs. The origins of these colorful crustaceans, which have long been sold as pets, have eluded scientists for years. Now, researchers have given them official names, and traced them to their Indonesian source.Read more...

Bringing Fish Up from the Deep Fish that live in the twilight zone region of the ocean are a crucial part of a vastly under-studied ecosystem. When fish are brought up to the surface for study, the change in pressure between their native depth (200-500 feet) and sea level often causes fatal damages to their anatomy. Watch how a team of scientists from the California Academy of Sciences designs and builds a portable chamber that creates a pressure-controlled environment for these animals, so […]
