What is causing the waves in California to glow? It looks like something from the movie "Avatar": ocean waters that light up like neon glow sticks when they splash.
Beaches across southern California have recently been alight with eerie, glowing waves. What could be causing such an otherworldly phenomenon? A recent report by Discovery News has provided an answer. According to marine biologist Jorge Ribas, the glowing is caused by a massive red tide, or algae bloom, of bioluminescent phytoplankton called Lingulodinium polyedrum. The microorganisms emit light in response to stress, such as when a wave crashes into the shore, a surfboard slashes through the surf, or a kayaker's paddle splashes the water.
The phenomenon has been observed on a semi-regular basis since at least 1901 along the beaches around San Diego, Calif. Galapagos' new star tortoise does what Lonesome George didn't: Helps save his species. QUITO, Ecuador - Lonesome George's inability to reproduce made him a global symbol of efforts to halt the disappearance of species.
And while his kind died with him, that doesn't mean the famed giant tortoise leaves no heir apparent. The Galapagos Islands have another centenarian who fills a shell pretty well. He's Diego, a prolific, bossy, macho reptile. Inhaltsverzeichnis - Tierenzyklopaedie.de. Plants by Type: herb.

We already know bees are pretty good at facial recognition, and researchers have shown they can also be effective air-quality monitors.
Here's one more reason to keep them around: They're smarter than computers. Bumblebees can solve the classic "traveling salesman" problem, which keeps supercomputers busy for days. They learn to fly the shortest possible route between flowers even if they find the flowers in a different order, according to a new British study. The traveling salesman problem is an (read: very hard) problem in computer science; it involves finding the shortest possible route between cities, visiting each city only once.

In March 2012, Carbon Tracker’s seminal report ‘Unburnable Carbon’ was Highly Commended in the City of London’s Sustainability Awards. This award-winning analysis by Carbon Tracker discovers that: Already in 2011, the world has used over a third of its 50-year carbon budget of 886GtCO2, leaving 565GtCO2 All of the proven reserves owned by private and public companies and governments are equivalent to 2,795 GtCO2Fossil fuel reserves owned by the top 100 listed coal and top 100 listed oil and gas companies represent total emissions of 745GtCO2Only 20% of the total reserves can be burned unabated, leaving up to 80% of assets technically unburnable (click image for larger version of map) Distribution of reserves across exchanges.

WebsterFriday, September 23, 2011 16:48 EDT Scientists at the Penn State College of Medicine said this week they have discovered a virus that is capable of killing all grades of breast cancer “within seven days” of first introduction in a laboratory setting. The virus, known as adeno-associated virus type 2 (AAV2), is naturally occurring and carried by up to 80 percent of humans, but it does not cause any disease. Researchers learned of its cancer-killing properties in 2005, after Penn State scientists observed it killing cervical cancer cells.
They also found that women who carried the AAV2 virus and human papillomavirus (HPV), which causes cervical cancer, had a lower propensity to develop cervical cancer. When combined in a lab recently, AAV2 eradicated all the breast cancer cells “within seven days,” according to researchers. The Center for Disease Control says that breast cancer is the most common type of cancer affecting American women. Copyright 2011 The Raw Story. Blood Types Tutorial. How Evolution Happens. GCSE Biology Revision. Arctic Warming is Altering Weather Patterns, Study Shows. EDITOR'S NOTE: This story was originally published April 3.
Given recent news that Arctic sea ice set a record low, it's a reminder that changes in the Arctic can affect the U.S. and Europe. By showing that Arctic climate change is no longer just a problem for the polar bear, a new study may finally dispel the view that what happens in the Arctic, stays in the Arctic. The study, by Jennifer Francis of Rutgers University and Stephen Vavrus of the University of Wisconsin-Madison, ties rapid Arctic climate change to high-impact, extreme weather events in the U.S. and Europe.

Clean bill of health: Scientists have shown that clearing damaged protein from the liver helps stop age decline in the organ (Source: iStockphoto) Scientists have stopped the ageing process in an entire organ for the first time, a study released today says.
Published in today’s online edition of Nature Medicine, researchers at the Albert Einstein College of Medicine at Yeshiva University in New York City also say the older organs function as well as they did when the host animal was younger. The researchers, led by Associate Professor Ana Maria Cuervo, blocked the ageing process in mice livers by stopping the build-up of harmful proteins inside the organ’s cells. As people age their cells become less efficient at getting rid of damaged protein resulting in a build-up of toxic material that is especially pronounced in Alzheimer’s, Parkinson’s and other neurodegenerative disorders. By contrast, the livers of normal mice in a control group began to fail. The Spooky World Of Quantum Biology. Michael Garfield The new science of quantum biology is teaching us about how the actual behavior of evolution is governed by disconcertingly spooky processes – time travel being one of them.
Will quantum computation finally be realized by biomimicry, in organic systems? Evolution is the new (old) computation...and we're about to take the reins. One hundred and fifty years ago, paleontologist Thomas Henry Huxley (an autodidact and philosopher who coined the term “agnostic” and was known as “Darwin’s Bulldog” for his passionate defense of natural selection) asserted that humankind would eventually take the processes of evolution into our own hands.

'Red deer people' lived 14,500-11,500 years ago in AsiaPreviously thought that homo sapiens had continent to themselves'Highly unusual' mixture of ancient and modern - could be new speciesCould also be relic of early migration out of Africa which died out By Rob Waugh Published: 15:00 GMT, 14 March 2012 | Updated: 09:27 GMT, 16 March 2012 Four Stone Age people found in caves in China could be a entirely new species of humanoid - and the discovery 'opens a new chapter' in the history of evolution, say archaeologists. The fossils, found in two caves, belong to a previously unknown Stone Age people and have a 'highly unusual' mixture of ancient and modern features.
Named the 'Red Deer people' because of the animals they hunted and dating from between 14,500 to 11,500 years ago, they are the youngest humanoid fossils to be found in Asia. Effet Baldwin.

Dans La Vie est belle, le paléontologue Stephen Jay Gould note que “l’iconographie au service de la persuasion frappe (…) au plus profond de notre être”. Pour introduire à une réflexion d’envergure sur l’histoire de la vie, le savant s’en prend à une illustration: la fameuse “marche du progrès”, dont il reproduit plusieurs parodies. La succession des hominidés en file indienne, “représentation archétypale de l’évolution – son image même, immédiatement saisie et instinctivement comprise par tout le monde”, propose une vision faussée d’un processus complexe. “L’évolution de la vie à la surface de la planète est conforme au modèle du buisson touffu doté d’innombrables branches (…).

Tooth decay to be a thing of the past? Enzyme responsible for dental plaque sticking to teeth deciphered. The Groningen professors Bauke Dijkstra and Lubbert Dijkhuizen have deciphered the structure and functional mechanism of the glucansucrase enzyme that is responsible for dental plaque sticking to teeth. This knowledge will stimulate the identification of substances that inhibit the enzyme. Just add that substance to toothpaste, or even sweets, and caries will be a thing of the past.
The results of the research have been published this week in the journal Proceedings of the National Academy of Sciences (PNAS). The University of Groningen researchers analysed glucansucrase from the lactic acid bacterium Lactobacillus reuteri, which is present in the human mouth and digestive tract.
