What Octopus and Human Brains Have in Common - Neuroscience News

Summary: Octopuses have a massively expanded repertoire of miRNA in their neural tissue, reflecting a similar development to that which occurred in vertebrates. Findings suggest miRNA plays a significant role in the development of complex brains.

Cephalopods like octopuses, squids and cuttlefish are highly intelligent animals with complex nervous systems. In “Science Advances”, a team led by Nikolaus Rajewsky of the Max Delbrück Center has now shown that their evolution is linked to a dramatic expansion of their microRNA repertoire.

If we go far enough back in evolutionary history, we encounter the last known common ancestor of humans

According to a new study, fossils of a tiny sea creature with a delicately preserved nervous system solve a century-old debate over how the brain evolved in arthropods, the most species-rich group in the animal kingdom.

Fossils of a tiny sea creature that died more than half a billion years ago may compel a science textbook rewrite of how brains evolved.

A new study provides the first detailed description

SpaceX launches tomato seeds, other supplies to International Space Station - CNN

CNN  — 

SpaceX is carrying a fresh haul of supplies to the International Space Station this weekend after bad weather at the launch site forced the company to wave off its first attempt.

The mission took off from NASA’s Kennedy Space Center in Florida around 2:20 p.m. ET Saturday. The original liftoff date had been Tuesday.

The bounty of supplies on board includes a pair of new solar arrays for the space station, dwarf tomato seeds and a range of science experiments. There will also be treats for the astronauts on the space station, like ice cream and Thanksgiving fare
