Phys.org / Cracking sleep's evolutionary code: Neuron protection traced back to jellyfish and sea anemones

A new study from Bar-Ilan University shows that one of sleep's core functions originated hundreds of millions of years ago in jellyfish and sea anemones, among the earliest creatures with nervous systems. By tracing this ...

Phys.org / Rare 'firework morphology' of supernova remnant Pa 30 may be due to white dwarf wind

In 1181 AD, a bright "guest star" was observed to linger in the sky for around six months. Nearly 850 years later, the likely remnants of this event were rediscovered and tentatively linked to the 1181 supernova and dubbed ...
