The fish species is separated from mammals by hundreds of millions of years of evolution, yet its seemingly primitive brain can handle many of the same elaborate visual tasks.
Many species of birds and other vertebrates form pair bonds and mate with just one other individual for much of their lives. But the unions don’t always work out. Scientists want to know the underlying factors.
A handful of new studies moves the needle toward a consensus on the long-disputed question of whether insect wings evolved from legs or from the body wall, but the devil is in the details.
Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.
An expert panel will describe their efforts to chart billions of neuronal connections and discuss how this data provides unparalleled insight into neuronal cell biology, signal processing, and behavior.
Our perception of quantity, separate from counting or estimation of magnitude more generally, is foundational to human cognition, according to some neuroscientists.
