Snippet Of RNA Helps Make Individuals Remarkably Alike

Uniformity, or singleness of form, is a general property of life. Biologists have long pondered how this feature is produced in the face of such great variation in genetics and environmental conditions. Researchers now have identified a microRNA that is critical to the robustness of the molecular network that helps regulate uniformity. This knowledge could lead to a better understanding of cancer cells, which do not act in controllable, uniform ways.

By Creating Market in Fakes, eBay Protects Archaeological Treasures

2164085293_9551d201db_b
When eBay was founded ten years ago, archaeologists feared it would create a convenient global marketplace for stolen antiquities, spurring the looting of archaeological sites. Their fears proved unfounded.

By creating a market for fake antiquities, the online auction giant has actually reduced looting pressures, writes UCLA archaeologist in Archaeology.

According to Stanish, communities that would once have supported themselves by raiding nearby ruins now devote themselves to churning out forgeries. “Chinese, Bulgarian, Egyptian, Peruvian and Mexican workshops are now producing fakes at a frenetic pace,” he writes.

By using eBay to sell directly to customers and cutting out middlemen who once transported their finds to black-market buyers, forgers actually make more money than before, and have little incentive to loot.

Their fakes are increasingly well-made, to the point where Stanish often can’t distinguish them from genuine items, and have flooded the global antiquities market. Stanish estimates that 95 percent of eBay’s purported archaeological treasures are forgeries, up from 50 percent a decade ago.

Would-be buyers of authentic artifacts are more skeptical than ever, further driving down the price of genuine antiquities.

“The value … of illicit digging decreases every time someone buys a ‘genuine’ Moche pot for $35, plus shipping and handling,” he writes.

Anaconda wave-power generator snakes into next stage of production

The device is said to be at the forefront of a new generation of wave-power machines that could slash renewables costs

Giant rubber sea snakes could harness the plentiful clean power off Britain's coasts within five years, according to the inventors of a new type of wave-energy generator.

Yesterday, Checkmate Sea Energy unveiled the final stages of a proof-of-concept trial of its Anaconda device, seen by many experts as at the forefront of the next generation of robust, cheap wave-power machines that could slash the costs of making renewable electricity.

Made from a composite of fabric and natural rubber, the Anaconda rides oncoming waves and uses the motion to drive a turbine in its tail. The test device is nine metres long but its developers say that a full-scale device could be up to 200m in length and be capable of producing 1MW of power, enough for a thousand homes, and cost £2m to build. Farms of 50 or more could be placed underwater a few miles from the coast.

Harnessing wave power could contribute significantly to the UK's target of sourcing 15% of its energy from renewable sources by 2020. The Carbon Trust found that wave and tidal stream technologies could add 10-20GW of electricity capacity to the UK by 2050, in particular from areas such as north-west Scotland and south-west England.

"It's a completely new kind of wave power machine," said Rod Rainey, a chief engineer with engineering design consultants Atkins and inventor of the Anaconda. "The beauty of wave energy is its consistency. However, the problem holding back wave energy machines is they tend to deteriorate over time in the harsh marine environment. Anaconda is non-mechanical: it is mainly rubber, a natural material with a natural resilience and so it has very few moving parts to maintain."

Each Anaconda device is tethered to the sea floor and positioned head-on into the coming waves. Floating under the sea surface, the water-filled rubber tube swims with the waves – as a swell hits the front of the device, it creates a bulge that travels to the back of the tube, in the same way a pulse of blood travels along an artery. When the bulge wave reaches the Anaconda's tail, the energy is used to drive a turbine and create electricity.

"Wave power has always been the poor relation of wind energy, but a lot of people are resentful of wind turbines on their doorstep, or in vast tracts of coastal waters," said Paul Auston, chairman of Checkmate. "What we're offering […] is a new technology which you can't see, it's under the water so it's not as intrusive and it's made of a natural material."

The device has already been given a significant vote of confidence by the Carbon Trust. The Anaconda has been chosen as one of only two technologies to take part in the Trust's marine accelerator programme, which aims to push new low-carbon technology ideas closer commercial reality.

"We were attracted to it because of its simplicity – in theory it's just a rubber structure," said the Carbon Trust's Stephen Wyatt. "It has the potential to be robust and quite easy and cheap to manufacture. When you look at some of the severe offshore conditions that wave and tidal devices have to face, then we realise that a structure this simple could be quite cheap."

Their analysis of the technology concluded that, because of this simplicity, Anaconda could create a "step-change" in how soon wave devices became commercial. Their research showed that, while wave energy in general costs around 25p per KWh to make, the anaconda had the potential to bring prices down to around 9p per KWh. Mains electricity today form fossil fuels costs around 6p per KWh.

Marine energy devices that are nearing commercial reality today include the SeaGen and Pelamis, a tidal and wave generator respectively. Both went into trials in the sea last year, SeaGen in Strangfod Lough and Pelamis off the coast of Portugal. Like Anaconda, Pelamis also uses a snake-like motion to capture wave energy by flexing its articulated metal sections on the sea surface. Both devices have had technical problems however, mainly due to the harsh conditions at sea.

The Anaconda's designers stress that its key advantage is its survivability. "If the worst comes to the worst it'll only be washed up on the beach, and you can patch it up and put it back out there," said Rainey.

The proof-of-concept trials have been carried out for the past few weeks in a wave tank at defence company QinetiQ in Gosport, Hampshire. When these are complete, Checkmate hopes to build a quarter-size version of Anaconda for possible sea trials. If all goes well, the Checkmate thinks the first devices in commercial production could be floating in the seas off Britain as early as 2014.

Obituary: Nina Farhi

Eminent psychoanalyst, teacher and lecturer

Nina Farhi, who has died of cancer aged 65, was an exceptional and respected psychoanalytic psychotherapist. In the 1980s she met, and subsequently became a close friend and colleague of, the psychoanalyst Marion Milner, an original theoretician who emphasised the healing power of unconscious psychic creativity. Milner suggested to Farhi that she should take her work into arenas where, for reasons of age, Milner herself could no longer go. With characteristic courage, generosity and intellectual thoroughness, Farhi took Milner's legacy as her li fe's work. She was involved, through her long career, with extremely damaged and disturbed people in intensive, four- or five-times weekly psychoanalytic therapy.

She lectured extensively in London and internationally and became a visiting lecturer at Bar Ilan University, near Tel Aviv. Her series of groundbreaking papers, in journals such as Contemporary Psychoanalysis and Psychoanalytic Dialogues, explored the ways in which, in work with patients from backgrounds of extreme emotional deprivation, she sought the most primitive elements that had enabled some form of psychological survival. Unafraid to draw from Jewish mysticism as well as a range of psychoanalytists, she could see the spark of holiness in the domain of evil, the drive towards self-realisation in bizarre and chaotic experiences with her patients.

Nina had recently finished an insightful, creative extension of an initative by Milner, who died in 1998. This paper, In the Hands of the Living God (echoing the title of Milner's 1969 publication, The Hands of the Living God), will be published posthumously in Psychoanalytic Dialogues. Prior to her death Nina was compiling notes for two major papers on perversion and anorexia, both earmarked for the same journal.

She was born Nina Ruth Gould in troubled lower-middle-class circumstances in north London. Her grandparents had been Polish and east Galician Jewish immigrants who had settled in the East End. Unsurprisingly, Nina became intensely involved in the class and racial politics of her day. Ill-health prevented her from pursuing a PhD thesis on a historical perspective on immigrants, particularly Jews who came to the UK in the early 20th century. Later, when her chronic condition, lobular hepatitis, became manageable, she turned to psychoanalysis and rose rapidly to prominence.

Nina became an inspirational teacher and supervisor in her training organisation, the Guild of Psychotherapists, and remained on their training committee for 10 years from 1989 to 1999. For many years, she supervised the staff team at the Whittington hospital's erstwhile Belle Ridley Day hospital (now the Dartmouth Park Unit), an NHS psychiatric unit in north London committed to the long-term care and treatment of some of the most damaged people in our society.

She was a founder member in 1980 of the Squiggle Foundation, the organisation devoted to the work of the pioneering psychoanalyst and paediatrician Donald Winnicott. During her time as director (1989-96), Nina held regular Saturday meetings in her home on themes in his work. Many of the participants became well-known clinicians and authors, within and outside psychoanalysis.

As Nina was unstintingly generous in her work, so she was with her friends, colleagues and the many people who sought her counsel. She became a mentor - through her robust and sometimes proud personal example of her faith in the possibilities of what a life could achieve and become - and all this through long-term illness, disability and pain that was determinedly shrugged off.

She had been afflicted with systemic lupus erythematosus from the early 1980s: this was never allowed to impinge on her plans for her own life or those of others. Her friends were so accustomed to her resolute denial of physical pain and her indomitable spirit that none of us recognised in her deteriorating physical condition the possibility of a terminal illness; and nor did she.

She is survived by her husband, Musa (the novelist Moris Farhi), whom she married in 1978, her daughter Rachel (Sievers), and her granddaughter Zara.

• Nina Farhi, psychoanalytic psychotherapist, born 1 December 1943; died 21 March 2009

Viral Missing Link Caught on Film

mimivirus3

A virus so large and strange that it’s redefined the very concept of a virus has been photographed for the first time. It’s even weirder than expected.

The virus was originally discovered infecting amoebas in a Parisian water tower in 1992. It was orders of magnitude bigger than any other virus — so large, in fact, that researchers figured it was a microbe.

It took 11 years for the mimivirus to be officially defined as a virus, though the definition didn’t quite fit. In addition to its enormous size, many of its genes came from bacteria. Some researchers called it a “missing link” that blurred the boundaries between viruses and living cells, between living and dead.

Despite all this attention the mimivirus’ physical structure remained a blur. Like other viruses, it was made from DNA surrounded by a protein coat called a capsid, but long fibers on the capsid’s surface made it difficult to see the mimivirus’ underlying structure.

To get a clearer picture, French and American biochemists dissolved mimivirus fibers with enzymes, then used an electron microscope to take thousands of pictures that were eventually combined into a three-dimensional structure. The results, published recently in Public Library of Science Biology, provide further evidence that mimiviruses straddle the boundary between virus and bacteria.

Whereas the DNA of other viruses are tightly wrapped, there’s a large gap between the mimivirus genome and its capsid. In some ways, this resembles less the structure of a virus than of a living cell, in which DNA is contained in a nucleus, which in turn floats in cell-wall-enclosed cytoplasm.

“The new structural finds, along with previous genetic and morphological work, confirm that mimivirus is an odd mix of genes and parts found in viruses, bacteria and even eukaryotes, the organisms that sequester their DNA in a nucleus,” write the researchers.

What does this mean, then, for the mimivirus’ official status, which has caused some researchers to call for a redefinition of virus?

Perhaps that’s the wrong question to ask. Eugene Koonin, a National Center for Biotechnology Information researcher who reported last year that, in another viral first, mimiviruses can actually become infected by other viruses, was nonplused by arguments over mimivirus classification.

“They’re part of the biosphere, and that’s more than enough for me,” he said at the time.
