Probiotics and "Science by Product Release" When heavy publicity turns early scientific findings into massive public debacles—see: Life, arsenic—we spend a lot of time talking about the problems inherent in doing science by press release. Essentially, an early finding might be pretty damn intriguing. But an early finding doesn't mean much until it's been picked apart by other scientists, and held up to criticism and verification. The process of science is glacially slow, while the news cycle moves like a waterfall. But there's another place in public life where the speed of good science conflicts with outside demands. Namely: The food industry. There's certainly a scientific basis for humankind's relationship with symbiotic bacteria, and there's also research suggesting that you can ingest these bacteria and benefit from it. What about the immune system? That last sentence is particularly important when it comes to safety.

Ils accusent les dromadaires qui peuplent leur île-continent d’être en partie à l’origine du réchauffement climatique. C’est le Département de l’efficacité énergétique et du changement climatique australien qui a proposé cette idée, laquelle lui avait été soufflée par une entreprise privée spécialisée dans la gestion des populations animales.

The scanning electron microscope has become one of the most powerful scientific visualization tools available, giving us incredible close-up views of anything from volcanic ash to snowflakes to bacteria.The microscope works by scanning a focused beam of electrons across an object. The electrons interact with the atoms at the surface of the object, revealing the texture and structure with a depth of field that makes for a great three-dimensional sense of the target.

Some of the most intriguing images are those of insects and other animals.On this day in 1940, the first transmission (stationary) electron microscope, predecessor to the scanning electron microscope, was demonstrated in the United States.

Ant Rafts Repel Water Like Gore-Tex | Wired Science. In the first serious study of the physics of fire-ant rafts, researchers have described how the insects form floating, waterproof islands. In nature, the rafts allow fire ants to survive epic rainstorms in their native Brazil. In the lab, they could help inspire designs for small, swarming robots that might someday be used to explore inaccessible areas or even clean up oil spills.

“The ant raft, up to this point, has been little more than just categorized and documented,” said mechanical engineer Nathan Mlot of the Georgia Institute of Technology, lead author of a paper in the April 25 Proceedings of the National Academy of Sciences. “We were coming at it from an engineering perspective.” Even though ants’ exoskeletons naturally repel water, a lone ant dropped in a bucket will flounder. But whole colonies of fire ants can float downstream for weeks at a time when flushed from their underground nests. “How are the ants actually linking in the raft?”

Stabbing, crushing, spitting and seducing are some of the more unusual, gruesome and clever ways spiders catch and kill their prey.Though these predators are best known for ensnaring their food in sticky webs and paralyzing them with venom, this is only one of many ways the world's 40,000 or so known spider species catch a meal.Spiders are found everywhere from rain forests to deserts, and can even be found in tide pools along the coast.

What they eat, and how they capture it, is just as varied as where they live. Spiders catch and consume insects, other spiders and even small animals including snakes and birds.Here are some of our favorite attack strategies.Above:Fishing Spider This widely distributed group of spiders lives near water and fishes for aquatic insects, small fish and frogs. Fishing spiders wait near water, typically with their front legs resting on the surface to detect the vibrations of potential prey. These arachnids have a taste for other spiders.

Christophe Hondelatte prend perpette. Pause en musique. Affaire DSK : jusqu'à la nausée. A moins de vivre sur une île déserte coupée de tout média, depuis deux semaines nous prenons tous notre petit-déjeuner avec DSK. Ensuite, nous partons bosser, DSK marchant à nos côtés. Arrivés au boulot, DSK se tient derrière nous et nous passons une matinée studieuse en sa compagnie, avant de l'emmener déjeuner. Le soir venu, nous le ramenons à la maison et l'invitons à partager notre dîner. Et quand nous nous couchons, nous lui faisons bien évidemment une petite place dans notre lit. Éviter DSK ? Je crois en l'information. Or, si l'on excepte les contenus factuels purement informatifs sur l'affaire DSK (et ils deviennent relativement rares, ces derniers jours), j'ai beaucoup de mal à percevoir dans les actuelles analyses, pullulant de tous côtés et se superposant les unes aux autres de façon souvent hasardeuse, un quelconque rapport avec une réelle information.

Et puis la semaine 1 de l'an zéro après DSK s'est achevée. Gulf spill endangers rare batfish. Gulf spill endangers rare batfish The bottom-dwelling pancake batfish is likely to feel the oil's impact. The oil pouring into the Gulf of Mexico has put two newly-discovered bottom-dwelling species of fish into danger, researchers say. The two newly-named species, Halieutichthys intermedius and H. bispinosus, are a type of fish called pancake batfish which have round, flat bodies with giant heads and mouths they can thrust forward. The rarity of these species is due to the dark depths they favor. The pancake-flat fish feed on tiny invertebrates in the shallow waters off the southern US coastline, from Louisiana to North Carolina. "Its entire habitat is in the region of the oil spill," said Prosanta Chakrabarty of Louisiana State University, one of the scientists who identified the two species.

He told OurAmazingPlanet.com that he was concerned the spill will kill off the fishes' food supply, and that the oil itself may reach the shallows where the batfish find their food.

Zoologger: Genetic superpowers of the common shrew - life - 28 April 2011. Zoologger is our weekly column highlighting extraordinary animals – and occasionally other organisms – from around the world Species: Sorex araneus Habitat: throughout northern Europe and northern Asia, thumbing its pointy nose at convention At first glance the common shrew is unremarkable. Between 5 and 8 centimetres long, it looks like a mouse with a pointed nose, or perhaps a miniature mole. If you saw it scurry through a field, you would barely give it a second glance.

But in fact the common shrew is still another animal that makes humans look like wimps. They are divided into at least 68 different races, which look alike but are distinguished by wholesale genetic rearrangements. Dance of the chromosomes DNA is organised into chromosomes, and each cell of an animal usually carries two copies of each, one inherited from the mother and one from the father. Sperm and egg cells, however, contain just one copy of each chromosome. Carry on karyotyping More From New Scientist More from the web. Les Beastie Boys: Hip Hop sans date de rédemption | Cultiz. MIT Researchers Use Viruses To Build More Efficient Solar Panels. Teams of viruses can help build better solar panels by ensuring nanoscale components behave properly, according to a new study. MIT researchers say their virus-assisted breakthrough could improve solar panels' energy conversion efficiency by one-third. Scientists already knew that carbon nanotubes, rolled-up sheets of graphene, could improve the efficiency of photovoltaic cells.

Ideally, the nanotubes would gather more electrons that are kicked up from the surface of a PV cell, allowing a greater number of electrons to be used to produce a current. But there are complications — carbon nanotubes come in two varieties, functioning either as semiconductors or wires, and they each behave differently. They also tend to clump together, which makes them less effective at gathering up their own electrons. MIT researchers found that a certain bacteria-attacking virus called M13 can be used to make things go more smoothly. "A little biology goes a long way," Belcher said in an MIT News article.

Les princesses existent-elles ? - Le blog de La Coquinerie.
