Are you looking at me? Scientists discover bizarre flatworm with 60 eyes Flatworm is completely new speciesDiscovered in grassland near CambridgeBelieved to be of Antipodean descent By Mark Prigg Published: 13:14 GMT, 23 July 2012 | Updated: 08:36 GMT, 24 July 2012 It is one of the oddest creatures ever found. Scientists today revealed an entirely new species of flatworm. The unique animal has 60 eyes, all crammed into a body just 12mm long. The UK's first 60 eyed flatworm has been discovered on a nature reserve in Cambridge. The creature was found in grassland near Cambridge despite the area being described as the most 'documented place on the planet'. The 12mm worm was found by Brian Eversham, chief executive of the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire. The peculiar invertebrate is thought to be of antipodean descent, but also a close relative of a species found in Northern Ireland called Kontikia Andersoni. Biologist Dr Hugh Jones, an expert in the field, believed it was a 'completely new, undescribed species'.

Biologija.com.hr - Vijesti - Biologija - Zašto je nekih vrsta na Zemlji mnogo, a nekih malo? Na svijetu postoji više od 400.000 vrsta kornjaša (skupina kukaca), a samo dvije vrste tuatara ili premosnika, rođaka zmija i guštera, koji živi na sjeveru Novog Zelanda. Zašto evolucija stvara ''pobjednike',' kao što su sisavci i mnoge vrste ptica i riba, a zašto ''gubitnike'' i dalje je jedno od središnjih pitanja evolucijske biologije. Premosnici (Sphenodon) su jedini recentni rod reda Rhynchocephalia u razredu gmazova. Pored toga, jedini su recentni predstavnici porodice Sphenodontidae. Obitelj premosnika predstavljaju samo dvije vrste, Sphenodon punctatus (naslovna fotografija) i, još rjeđa, Sphenodon guntheri. Znanstvenici su pretpostavljali da je vrijeme glavni čimbenik koji utječe na broj vrsta - što su neke životinjske i biljne linije starije od ostalih, iz njih se mnogo više vrsta imalo vremena razviti. Druga teorija, da su neke skupine urođeno bolje ili lošije u proizvodnji vrsta, također ne objašnjava razlike u broju vrsta među glavnim živućim linijama biljaka i životinja.

Rare and Precious Moments of Animal Life How interesting can animal life be is something which we can only guess. By looking these amazing photographs it seems that they have very funny and precious moments. Would you like to be monkey, or elephant, or maybe cat sometimes? The Genetic Gamesmanship of a Seven-Sexed Creature | Discoblog What could be better than two types of sexes? For one organism, the answer isn’t three, but seven! And to top it off, these seven sexes aren’t evenly distributed in a population, although researchers have now developed a mathematical model that can accurately estimate the probabilities in this crap-shoot game of sexual determination. Meet Tetrahymena thermophila, which in addition to its seven different sexes—conveniently named I, II, III, IV, V, VI, and VII—has such a complex sex life that it requires an extra nucleus. This fuzzy, single-celled critter has a larger macronucleus that takes care of most cellular functions and a smaller micronucleus dedicated to genetic conjugation. The other odd thing about this one-celled wonder is that the population of the seven sexes are skewed, leading Unversity of Houston researcher Rebecca Zufall and her colleagues to ask: What gives?

Innovative Brain Imaging Combines Sound And Light Lihong Wang uses light and sound to create highly detailed images of the living brain. Chris Nickels for NPR hide caption toggle caption Chris Nickels for NPR Lihong Wang uses light and sound to create highly detailed images of the living brain. Chris Nickels for NPR Lihong Wang creates the sort of medical technology you'd expect to find on the starship Enterprise. Wang, a professor of biomedical engineering at Washington University in St. "It's really about turning some of these ideas that we thought were science fiction into fact," says Richard Conroy, who directs the Division of Applied Science & Technology at the National Institute of Biomedical Imaging and Bioengineering. Wang's ultimate goal is to use a combination of light and sound to solve the mysteries of the human brain. Wang describes himself as a toolmaker. "We want to conquer the brain," Wang says. Current brain-imaging techniques such as functional MRI or PET scans all have drawbacks. Wang's initial idea was to use light.
Ancient City Found in India, Irradiated from Atomic Blast Radiation still so intense, the area is highly dangerous. A heavy layer of radioactive ash in Rajasthan, India, covers a three-square mile area, ten miles west of Jodhpur. Scientists are investigating the site, where a housing development was being built. For some time it has been established that there is a very high rate of birth defects and cancer in the area under construction. The Mahabharata clearly describes a catastrophic blast that rocked the continent. "A single projectile charged with all the power in the Universe…An incandescent column of smoke and flame as bright as 10,000 suns, rose in all its splendor…it was an unknown weapon, an iron thunderbolt, a gigantic messenger of death which reduced to ashes an entire race." A Historian Comments Historian Kisari Mohan Ganguli says that Indian sacred writings are full of such descriptions, which sound like an atomic blast as experienced in Hiroshima and Nagasaki.

Birds and humans have similar brain wiring You may have more in common with a pigeon than you realise, according to research. It shows that humans and birds have brains that are wired in a similar way. A researcher from Imperial College London and his colleagues have developed for the first time a map of a typical bird brain, showing how different regions are connected together to process information. By comparing it to brain diagrams for different mammals such as humans, the team discovered that areas important for high-level cognition such as long-term memory and problem solving are wired up to other regions of the brain in a similar way. This is despite the fact that both mammal and bird brains have been evolving down separate paths over hundreds of millions of years. The team suggest that evolution has discovered a common blueprint for high-level cognition in brain development. Professor Murray Shanahan, author of the study from the Department of Computing at Imperial College London, says:
Controlling RNA in living cells MIT researchers have devised a new set of proteins that can be customized to bind arbitrary RNA sequences, making it possible to image RNA inside living cells, monitor what a particular RNA strand is doing, and even control RNA activity. The new strategy is based on human RNA-binding proteins that normally help guide embryonic development. The research team adapted the proteins so that they can be easily targeted to desired RNA sequences. “You could use these proteins to do measurements of RNA generation, for example, or of the translation of RNA to proteins,” says Edward Boyden, an associate professor of biological engineering and brain and cognitive sciences at the MIT Media Lab. Unlike previous efforts to control RNA with proteins, the new MIT system consists of modular components, which the researchers believe will make it easier to perform a wide variety of RNA manipulations. “Modularity is one of the core design principles of engineering.

The Brain Preservation Foundation (BPF) has announced that a team at 21st Century Medicine led by Robert McIntyre, PhD., has won the Small Mammal Brain Preservation Prize, which carries an award of $26,735. The Small Mammalian Brain Preservation Prize was awarded after the determination that the protocol developed by McIntyre, termed Aldehyde-Stabilized Cryopreservation, was able to preserve an entire rabbit brain with well-preserved ultrastructure, including cell membranes, synapses, and intracellular structures such as synaptic vesicles (full protocol here). The judges for the prize were Kenneth Hayworth, PhD., Brain Preservation Foundation President and neuroscientist at the Howard Hughes Medical Institute; and Prof.
