The marine planarian, cuttlefish and Nile perch have one thing in common: in order to propel themselves, they use their fins to generate a continuous wave, which advances along their entire length. With this so-called undulating fin movement, the BionicFinWave also maneuvres through a pipe system (and at) the same time the autonomous underwater robot is able to communicate with the outside world wirelessly and transmit data
And really neat to watch too!
A researcher realizes that cancer cells share material via nanotubes. This might help cancer cells spread immunity to chemotherapy.

Founded in 2011, The Public Domain Review is an online journal and not-for-profit project dedicated to the exploration of curious and compelling works from the history of art, literature, and ideas.
In particular, as our name suggests, the focus is on works which have now fallen into the public domain, that vast commons of out-of-copyright material that everyone is free to enjoy, share, and build upon without restriction. Our aim is to promote and celebrate the public domain in all its abundance and variety, and help our readers explore its rich terrain – like a small exhibition gallery at the entrance to an immense network of archives and storage rooms that lie beyond.
We now know that all extant living creatures derive from a single common ancestor, called LUCA, the Last Universal Common Ancestor. It's hard to think of a more unifying view of life. All living creatures are linked to a single-celled creature, the root to the complex-branching tree of life. (...) They are able to trace LUCA to a simple prokaryotic creature (a single-celled bacterium with unprotected genetic material) that lived some 3 billion years ago. It must have been a very tough organism, able to survive in very extreme environments.
Researchers observe sleep-like behavior in jellyfish, a brainless organism :
(T)he revelations about jellyfish sleep are important, he said, because they show how basic sleep is. It appears to be a “conserved” behavior, one that arose relatively early in life’s history and has persisted for millions of years. If the behavior is conserved, then perhaps the biological mechanism is too. Understanding why jellyfish, with their simple nerve nets, need sleep could lead scientists to the function of sleep in humans.
Zika injections shrank aggressive tumours in fully grown mice, yet left other brain cells unscathed.
Human trials are still a way off, but experts believe Zika virus could potentially be injected into the brain at the same time as surgery to remove life-threatening tumours, the Journal of Experimental Medicine reports.

"Take one common jellyfish (Aurelia aurita), submerge it in 96 percent ethanol in a plastic box, stick it in the fridge for a few days, place on a baking sheet at room temperature to let the alcohol evaporate and, voila!, jellyfish chip."
