Zatoichi1337. Why some wasps are good with faces – and others aren't - life - 01 December 2011. You don't want to mess with Ms Big, so it's useful if you recognise her when you see her. So useful that even wasps can do it. Despite having a brain less than a millionth the size of ours, queen paper wasps (Polistes fuscatus) can recognise each other's faces . Michael Sheehan and Elizabeth Tibbetts, both at the University of Michigan in Ann Arbor, think they know why.

They suspected the wasps developed the skill to keep their home in harmony. The species forms large nests with several queens, and maintaining a pecking order between them is crucial for cooperation. "If the queens know their place, it reduces aggression and keeps the peace in the colony," says Sheehan. The nests of another related species – Polistes metricus – each contain a single queen, so Sheehan and Tibbetts reasoned that these queens would be bad with faces.

Maze of pain To test the idea, they released wasps of each species, individually, into a T-shaped maze with an electrified floor. "This is bizarre," says Sheehan. Browsing deviantART. Seychelles. Seychelles ( i/seɪˈʃɛlz/ say-SHELZ; French: [sɛʃɛl]), officially the Republic of Seychelles (French: République des Seychelles; Creole: Repiblik Sesel), is a 155-island country (as per the Constitution) spanning an archipelago in the Indian Ocean, whose capital, Victoria, lies some 1,500 kilometres (932 mi) east of mainland Southeast Africa, northeast of the island of Madagascar. Other nearby island countries and territories include Zanzibar to the west, Mauritius, Rodrigues, Agaléga and Réunion to the south, and Comoros and Mayotte to the southwest. Seychelles, with a population of 90,024, has the smallest population of any African state.[4] It has the highest Human Development Index in Africa and the highest income inequality in the world, as measured by the Gini index.

Seychelles is a member of the African Union. History[edit] Some scholars assume that Austronesian seafarers and later Maldivian and Arab traders were the first to visit the uninhabited Seychelles.

The Mail: Re: The Truth Wears Off. One development that Lehrer does not discuss, and that we believe has the potential to exacerbate the “decline effect,” is the trend toward the publication of brief reports in mainstream psychology journals.

Traditionally, an article in experimental psychology consisted of at least three experiments, the first demonstrating an important finding, and the others replicating it and establishing its boundary conditions. Today, there is a move away from such articles and toward one-experiment papers reporting a single unexpected result. Short reports demand less time of authors, reviewers, and readers, but an undesirable consequence is that findings are less likely to be replicated even by the investigators who first publish them. This increases the likelihood that a result initially received as exciting and novel will turn out to be nothing but a fluke.

Ancient Species Show Their Resilience, Highlight Need For Conservation (PHOTOS) From Dr. Piotr Naskrecki: What would you rather save from extinction: 3 different species of parrots, or a hummingbird, an owl, and a parrot?

With an increasing frequency, such heartbreaking choices are becoming the reality of nature conservation. Given their limited resources, and the even more limited attention span of politicians and governments, conservation biologists face the need to select targets of their conservation campaigns very carefully. What drove horseshoe crabs, relics of a lineage that blossomed in the Carboniferous, to leave the ocean every spring and lay trillions of eggs on the sandy beaches of Delaware Bay? But individual species and lineages are not the only relics that still grace the surface of our ancient planet.

Adobe fights back with Flash 11 | Deep Tech. Long gone are the days when Adobe Systems could take its Flash Player's position on the Web for granted. But Adobe, to counter a strong combination of opposition and alternatives to the browser plug-in, plans to ship Flash Player 11 in two weeks. The debut at its Max developer conference early next month is geared to send a message to programmers: Flash is still relevant, and Adobe is still investing in it. Flash 11's highlight, an interface called Molehill for hardware-accelerated 3D and 2D graphics, won't change the minds of those who would like to see Flash fade from the Web, nor will it reverse Apple and Microsoft's Flash opposition. But it is a powerful new feature for games, and games are one of the Flash strongholds Adobe is seeking to defend.

"WIth direct access to the GPU [graphics processing unit], you'll see a thousand times faster rendering over prior versions of Flash," said Danny Winokur, Adobe's platform general manager.

The Cosmic Serpent by Jeremy Narby takes a serious look at how neurogenetic consciousness informs awareness, knowledge, symbolism and culture. His comparison of the ancient cosmic serpent myths to the genetic situation in every living cell reveals the immortal biomolecular wizard behind the curtain of everyday life.

His anthropological study, ayahuasca experience and scientific speculations weave a tale of shamans who bring their consciousness down to molecular levels with sophisticated neurotransmitter potions in order to perceive information contained in the coherent visible light emitted by DNA. Some excerpts from this important book: As ayahuasquero Pablo Amaringo says: "A plant may not talk, but there is a spirit in it that is conscious, that sees everything, which is the soul of the plant, its essence, what makes it alive.
