A disco mollusk sends aggressive shrimp into a trance!

Panic of the Disco Clam

The mollusk’s flashy tactics scare off predators.

WIKIMEDIA, OPENCAGEThe so-called disco clam Ctenoides ales took the human world by storm last summer when researchers revealed the secret behind its flashing lips, but it was unclear how the light display might benefit the mollusk. This week (January 4), the same team of scientists proposed a potential explanation at the annual meeting of the Society for Integrative and Comparative Biology in West Palm Beach, Florida.  The clam’s blinking lips, together with a distasteful chemical discharge, help the animal to fend off fierce predators.

After coming across the disco clam on a dive in Indonesia, study coauthor Lindsey Dougherty of the University of California, Berkeley, and her colleagues determined that small beads of reflective silica nestled inside the edge of the clam’s quivering red lip were responsible for the light show. For a follow-up study presented at the meeting, the scientists tested three possible functions of this showy display: enticing potential mates, attracting prey, and scaring off predators.

The researchers found that the flash effect would be an ineffective mating display because the clams have poor vision. In the presence of both simulated predators and phytoplankton prey, however, the clam doubled its flashing rate. In the final test, the clams shared their tank with a fierce and powerful predator, the mantis shrimp.

Dougherty’s team was surprised to find that the clam’s flashes caused the shrimp to recoil and enter a catatonic state. “[Mantis shrimp] are very aggressive critters, and to have a clam open and flashing, and the mantis shrimp not attacking, is very weird,” Dougherty told LiveScience. Further tests revealed that the clam’s tentacles contained sulfur, an unpleasant-tasting chemical that could drive away shrimp and other foes. The scientists now hope to confirm the protective purpose of the clam’s behavior in the wild.

And there used to be music.  No longer.

In just the last few generations, we have witnessed the complete devolution of the mainstream of music from the intricacies and demands of jazz, swing and modern "classical"; the subtleties and finesse of the best of popular song writing; the mastery of "folk" instruments and vocal performance in the best of folk and rock; the singular high-mindedness of the greatest singer songwriters; and the hard-won craft of playing and writing and creating meaningful work, to four bar grids of "cut and paste" monotony over which someone writes shallow nursery rhymes about partying, trucks and beer or bitches and bling, or whines in hardly rhyming verse about their sad little white boy or girl life.

There are occasional exceptions, of course.  But where are the anthems, the protest songs, the songs to march to or the ideas to fight for, the truths to believe in.  Instead it's all about "me".

"Glory" from the film "Selma" is the great current exception - as is Kendrick Lamarr's work. And - yes - let's not forget the valiant Dixie Chicks!!  But mostly there's little more than a bit of catchy ear candy and nice beats.

All that talk about the "me generation" turns out to be true.  We lost "us" in the 80's and since then we only care about ourselves and our personal gain;  we only want the money.

The rhetoric endures - as it does in politics.  There's not a single human working in the "music industry" who doesn't say that they're in it for the music, for the art form.  Just like there's no politician who doesn't claim to be doing it to serve their country or community. But the reality is, we're all in everything for the pay off.  Period.

There used to be meaning.  No more.

With our music and words, we used to fight for freedom;  we used to incite change;  we used to elevate each other;  we used to speak for all of us and literally move mountains.

No more.

Thanks for reminding us of this, Bob.

Scientists %

As a scientist I completely endorse this video - however there is a little miscommunication is the statistics.  It is 97% of CLIMATE Scientists that agree. Not 97% of ALL Scientists (unfortunately there are still misinformed people in the science community - I think it is closer to about 80% for the whole community).

The Avengers is a lot of fun!

Avengers: Age of Ultron review – Whedon's heroic cavalcade of fun

4/5stars
    

The follow-up to The Avengers may be the harbinger of a new deluge of superhero movies, but if all turn out as entertaining as this one, what’s the problem?

Recently, there has been a shrill cultural panic at the thought of all the superhero movies due to be released in the next few years: Ant-Man, Captain America: Civil War, Doctor Strange, Guardians of the Galaxy 2, The Spectacular Spider-Man, Thor: Ragnarok, Avengers: Infinity War Part 1, Black Panther, Captain Marvel, Avengers: Infinity War Part 2, Batman vs Superman: Dawn Of Justice … the list goes on. But what’s the problem? For me, it’s no more of an issue than all the romcoms and horror the business is readying at the far end of the chute, and this exotic new strain of supers could well be stimulating the industry. And there’s certainly no problem if they’re as exuberant, funny, silly and crazily exhilarating as this new Avengers movie from writer-director Joss Whedon, which is a pure aspartame rush.

 Avengers: Age of Ultron: watch the trailer for Joss Whedon’s Marvel sequel

Once again, the Avengers have assembled under the mercurial and possibly duplicitous leadership of Tony Stark, otherwise Iron Man, played with the usual single-breath delivery of throwaway wisecracks by Robert Downey Jr. It’s a role which now threatens or promises to define his whole career. Previously, I have described the assembled Avengers as the Traveling Wilburys of superheroism. Now they are more like a G7 summit of world-saving and crime-fighting with every constituent member becoming a veritable Angela Merkel of demurely offbeat virility.

Mark Ruffalo is excellent as the troubled and introspective Dr Bruce Banner, for whom Hulk transition is not in and of itself a problem. The issue now is the way in which he must be coaxed into remorphing into human form and Black Widow, nicely played by Scarlett Johansson, is becoming the Hulk whisperer. The intuitive tenderness with which she deals with Banner/Hulk is turning into a sweet love affair: it seems to involve a great deal of delicately erotic hand-holding: her tiny hand in his galumphing green mitt; yet Dr Banner is holding back from returning her love, unwilling to burden her with his terrible rage potential. Chris Hemsworth is Thor, continuously resident on Earth for the time being and without claims from Asgard to distract him. (My one quarrel with the film is that Tom Hiddleston’s Loki doesn’t show up.) Chris Evans’s Captain America is a stolid reminder of wartime values and Jeremy Renner is Hawkeye, whose bow and arrow make him the quaintest and yet most romantic warrior of the group.

But now they find themselves up against a couple of new enemies: Pietro Maximoff, or Quicksilver, played by Aaron Taylor-Johnson, and his twin sister Wanda Maximoff, or Scarlet Witch, played by Elizabeth Olsen. They are blessed variously with super speed and mind control (as one character puts it, “he’s fast; she’s weird”) and Scarlet Witch almost immediately uses her head-messing capabilities to show a secretly aghast Stark how he might betray and even destroy his fellow Avengers.

But more importantly, Stark begins to experiment (without his comrades’ knowledge) with an artificial intelligence programme that could impose absolute power on Earth, supposedly to repel all enemies: this insubstantial mega-brain, like a floating blue jellyfish, instantly goes rogue, becoming a terrifyingly dangerous new enemy named Ultron, appropriating a new exoskeleton, and becoming a bizarro version of his effective creator: Stark. Ultron uses the blandly Chamberlain-esque phrase “peace in our time” to describe its planned totalitarian rule, the Pax Ultronica, and the irony will hardly be lost on the second world war veteran Captain America. The Avengers realise that they are actually fighting against a hideously parodic version of their own ally: Stark, his worst and perhaps even strongest self.

It’s all operatically mad, and the city-destroying final confrontation is becoming a bit familiar, but Whedon carries it off with such joy and even a kind of evangelism. His script is a thing of wonder, jam-packed with great lines: I loved Stark’s wearied remark: “I’ve had a long day … Eugene O’Neill long …” And the unresolved romantic and sexual tension between Black Widow and Hulk creates a weird driving force to the narrative: even the absurdity is somehow recirculated into the film’s internal economy as comedy and irony and the cast-of-thousands effect never seems to split the focus: Andy Serkis plays metal trader Ulysses Klaw and Julie Delpy has a blink-and-you’ll-miss-it cameo as Black Widow’s sinister former controller. It’s a superhero cavalcade of energy and fun.

Good idea to join the conversation on Earth Day

Unilever and the United Nations have partnered with Upworthy for a Twitter #UpChat on Earth Day (4/22/2015) from 1-2 p.m. Eastern to talk climate change, deforestation, and most importantly, solutions. Whether this is something you know a lot or a little about, we want you to join us. Consider this your formal invitation!

What better way to celebrate Earth Day than by having a conversation about what to do (and what's already been done) about climate change? Protecting the Earth doesn't have to be scary; in fact, it's the perfect opportunity to make some real changes for the better. And after the chat, hey, maybe you can plant a tree! Sounds like a fun spring afternoon, if ya ask us.
