Eben Bayer: Are mushrooms the new plastic?

7 podcasts à écouter absolument : 6 de Geeks 1 de finance Si l’internet regorge de support écrits et de vidéos, la partie audio serait peut-être le parent faible de l’internet. Je voulais mettre à jour cette liste avec des podcasts italiens, espagnols et allemands, voir portugais, mais ma quête au podcast est difficile, j’y a trouvé quelques podcast morts dont celui de makeuseoff et aujourd’hui je rajoute Geekcast.fm, Geekcastonline.com, Geeknewscentral.com Il doit exister sur le net des milliers de podcast passionnants à écouter. Le problème est de savoir lesquels écouter. Geekcast.fm (anglais) Trouvé récemment, geekcast est un podcast journalier qui cadre bien avec la ligne directrice de ce blog. Geekcastonline.com (anglais) Des tutorials par un geek qui n’a pas sa langue dans sa poche, plutôt des tutos que des actualités. je n’écoute pas tous les podcasts de ce site.

Great Pacific Garbage Patch The area of increased plastic particles is located within the North Pacific Gyre, one of the five major oceanic gyres. The Great Pacific garbage patch, also described as the Pacific trash vortex, is a gyre of marine debris particles in the central North Pacific Ocean located roughly between 135°W to 155°W and 35°N and 42°N.[1] The patch extends over an indeterminate area, with estimates ranging very widely depending on the degree of plastic concentration used to define the affected area. The patch is characterized by exceptionally high concentrations of pelagic plastics, chemical sludge and other debris that have been trapped by the currents of the North Pacific Gyre.[2] Despite its size and density, the patch is not visible from satellite photography, nor even necessarily to a casual boater or diver in the area, since it consists primarily of a small increase in suspended, often-microscopic particles in the upper water column.

Fighting Fire With Fire: Vampire Bacteria Has Potential as Living Antibiotic Listen to the UVA Today Radio Show report on this story by Fariss Samarrai: October 31, 2011 — A vampire-like bacteria that leeches onto specific other bacteria – including certain human pathogens – has the potential to serve as a living antibiotic for a range of infectious diseases, a new study indicates. The bacterium, Micavibrio aeruginosavorus, was discovered to inhabit wastewater nearly 30 years ago, but has not been extensively studied because it is difficult to culture and investigate using traditional microbiology techniques. However, biologists in the University of Virginia's College of Arts & Sciences, Martin Wu and graduate student Zhang Wang, have decoded its genome and are learning "how it makes its living," Wu said. The bacterium "makes its living" by seeking out prey – certain other bacteria – and then attaching itself to its victim's cell wall and essentially sucking out nutrients. "We have a map now to work with, and we will see where it leads," he said.

7 Alternative Fuels and Fuel-Powered Vehicles With $4.00/gallon gas prices a not-so-distant memory, alternative fuels are all the rage. But what about the vehicles that run on them? Between hydrogen fuel cells, bio diesel, electricity and compressed air, the industrialized world is hard at work creating the next generation of non-oil consuming vehicles. These new, eco-friendly chariots deserve at least as much attention and fanfare as the fuels that power them, especially these 7 models. Compressed air (Image via DanceWithShadows) Perhaps the most tantalizing of all the alternative fuels is compressed air. Vegetable oil (Image via Biodiesel.org) Environmentalists everywhere have been salivating at the idea of running a car on vegetable oil ever since the idea was first proposed, and we have now taken the leap from concept to reality! Hydrogen fuel cells (Image via ImagesMe) The prospect of hydrogen-powered cars has been enticing eco-friendly motorists for years. Ethanol (Image via InternetAutoGuide) Water (yes, water!)

researchers engineered molecule changes itself to detect and attack diseased cells L.A. Cicero Christina Smolke Imagine if your doctor could look for cancer in your body just by checking for green glowing cells, alerting her to the presence of the disease. Imagine further that she could convince any cancerous cells in your body to commit suicide, while leaving your healthy cells unaffected. In Friday's issue of Science, a Stanford researcher reported engineered biological "devices" that could one day offer these kinds of diagnostic and treatment options. These autonomous biological tools are called "sensor-actuator" devices because they sense what's happening in a cell and act upon what they detect. The researchers built these devices by combining different pieces of DNA into one long stretch. The sensor-actuator devices are built with efficient redesign in mind. Or the output could cause a diseased cell to kill itself. The sensor part of the RNA molecule can detect whether a certain protein is present simply by binding to it. Powerful tool for cells

How Much Oil is Left in the World? Over the next two to three weeks, I am going to post a series of short articles utilizing graphics I created from the recently released 2012 BP Statistical Review of World Energy. Because I am working on the roll-out of a new product which will be geared specifically toward those with a financial interest in the world of energy (more on that in the coming days), I will take a break from my video blogs during this time, and catch up on accumulated questions after I finish this series. World Oil Reserves Facts and Figures The topic of this first article in the series is oil reserves. Just to review, an oil resource refers to the total amount of oil in place, most of which can’t be recovered. Over the past 30 years, 90% of the reserves additions have come from OPEC countries. In 1982, OPEC introduced a system of production quotas based partly on the oil reserves in each country. Mystery of the Self-Replenishing Reserves In 1980, U.S. proved reserves were 36.5 billion barrels. U.S.

Chart Porn 10 Very Rare Cloud Pictures Showcasing cool pictures of rare clouds caught on camera. Clouds fill the skies above us and are part of our every day lives but often go unnoticed. However, there are some clouds that are so rare that you will be very lucky to see them in your lifetime. This is a list of the top 10 most rarest cloud formations (in no particular order) that for those lucky enough to see them, were caught on camera. For those of you more interested in clouds, we recommend Cloud Book: How to Understand the Skies 1. These rare clouds, sometimes called mother-of-pearl clouds, are 15 - 25km (9 -16 miles) high in the stratosphere and well above tropospheric clouds. They have iridescent colors but are higher and much rarer than ordinary iridescent clouds. Nacreous clouds shine brightly in high altitude sunlight up to two hours after ground level sunset or before dawn. Their unbelievably bright iridescent colors and slow movement relative to any lower clouds make them an unmistakable and unforgettable sight. 2. 3.

Oldest human ancestor found in lake sludge › News in Science (ABC Science) News in Science Friday, 27 April 2012 AFP Primordial life After two decades of examining a microscopic algae-eater that lives in a lake in Norway, scientists have declared it to be one of the world's oldest living organisms and human's remotest relative. The elusive, single-cell creature evolved about a billion years ago and did not fit in any of the known categories of living organisms - it was not an animal, plant, parasite, fungus or alga, they say. "We have found an unknown branch of the tree of life that lives in this lake. "So far we know of no other group of organisms that descends from closer to the roots of the tree of life than this species", which has been declared a new genus called Collodictyon. Scientists believe the discovery may provide insight into what life looked like on Earth hundreds of millions of years ago. Collodictyon lives in the sludge of a small lake called Ås, 30 kilometres south of Oslo. Not social creatures "They flourish best alone.

The six natural resources most drained by our 7 billion people | Environment With 7 billion people on the planet – theoretically from today – there will be an inevitable increase in the demand on the world's natural resources. Here are six already under severe pressure from current rates of consumption: 1. Water Freshwater only makes 2.5% of the total volume of the world's water, which is about 35 million km3. 2. The fear of reaching peak oil continues to haunt the oil industry. 3. A similar picture to oil exists for natural gas, with enough gas in proven reserves to meet 58.6 years of global production at the end of 2010. 4. Without this element, plants cannot grow. 5. This has the largest reserves left of all the fossil fuels, but as China and other developing countries continue to increase their appetite for coal, demand could finally outstrip supply. 6. Scandium and terbium are just two of the 17 rare earth minerals that are used in everything from the powerful magnets in wind turbines to the electronic circuits in smartphones.
