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

Aural Archipelago
Posted by Darwish in it's the arts 8 days ago
Aural Archipelago is the lovechild of Palmer Keen, an American DIY ethnomusicologist wandering the vast archipelago of Indonesia to find, document, expose and promote little-known traditional musics around the country. Within a few years, Palmer has travelled from vast islands like Sumatra, Java, and Borneo to small dots in the ocean like Rote and Selayar in search of the diverse and beautiful music that fascinates him. With this project, his hope is to allow unprecedented audiences (local and foreign) free access to music that is often difficult or impossible to hear otherwise.

When organizations turn a blind eye to sexual harassment in the workplace, how many people need to take a stand before the behavior is no longer seen as normal?

According to a new paper published to be published tomorrow in Science (link is external), there is a quantifiable answer: roughly 25% of people need to take a stand before large-scale social change occurs. This idea of a social tipping point applies to standards in the workplace, and any type of movement or initiative.


Online, people develop norms about everything from what type of content is acceptable to post on social media, to how civil or uncivil to be in their language. We have recently seen how public attitudes can and do shift on issues like gay marriage, gun laws, or race and gender equality, as well as what beliefs are or aren’t publicly acceptable to voice.
They are ugly, and they are poisonous. And now scientists have discovered that they carry switchblades.

Stonefish, a group that includes many species, have a previously unknown defensive weapon: a “lachrymal saber” in each cheek that can be drawn and retracted as needed.

A report of one instance of a stolen identity being used to sell digital books of spam-style text for $555 a copy. The fake author gets 60% of the selling price. Even at that rate, the criminal managed to "earn" nearly $24,000 .
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.

Through a combination of sobering real life stories and a treasure trove of data, researchers Heather Hunt and Prof. Gene Nichol explain how North Carolina is, quite literally, criminalizing poverty through the imposition of burdensome fines and fees that millions of people cannot afford.

Tales of Alaska’s gold rushes, which began in the 1890s, are full of larger-than-life men... But nestled among all the stories of men is the story of Fannie Quigley, a five-foot-tall frontierswoman who spent almost 40 years homesteading and prospecting in Kantishna, a remote Alaskan mining region that would later become part of Denali National Park...
Even chimpanzees and infants want to punish antisocial behaviour

Living together in communities requires mutual cooperation. To achieve this, we punish others when they are uncooperative. Until now, it has been unclear as to when we develop the impulse to penalise this behaviour—and whether this is an exclusively human feature. Scientists at Max Planck Institute...for Human Cognitive and Brain Sciences and the MPI for Evolutionary Anthropology...in Leipzig discovered that even six-year-old children feel the need to reprimand antisocial behaviour, and that they are willing to take risks and make an effort to be present when the "guilty" one is punished.
