Scientists have made a long-awaited breakthrough in human cloning, by using human skin cells to create early-stage embryos. The breakthrough marks the first time human stem cells have been produced via nuclear transfer and follows several unsuccessful attempts by research groups worldwide
In what is being described as a “significant milestone” for medicine, the team from Oregon Health and Science University successfully used a technique which utilised a human skin cell and a woman’s egg to produce an embryo which was a genetic copy of the original skin cell.
The resulting embryos were then used as a source of stem cells, which can be used to create specialised tissue cells for transplant operations. However scientists say they do not think the technique could be used to clone humans for reproductive purposes :: Read the full article »»»»

It’s proof perhaps that we live in an ironic world, Australian researchers are on the cusp of creating new human organs via 3D-printing. While a US student fires the first bullet from a home-made 3D Printed polymer gun.
On the up-side, Australian scientists say they have found a way to grow human body parts using 3D printing technology. The technology isn’t the only cleverness here, 3D printers are now so portable that they might be installed in hospitals.
The University of Wollongong’s Centre for Electromaterials Science is opening a research unit at Melbourne’s St Vincent’s Hospital where 3D printing will be used to reproduce tissue material :: Read the full article »»»»

Researchers from tech-behemoth IBM have unveiled – confirmed by Guinness World Records – the world’s smallest movie, made with atoms. Named A Boy And His Atom, the movie used thousands of precisely placed atoms to create nearly 250 frames of stop-motion action.
The movie depicts a character named Atom who befriends a single atom and goes on a journey that includes dancing, playing catch and bouncing on a trampoline. Set to a playful musical track, the movie represents a unique way to convey science outside the research community.
It takes around 1 million atoms to store a single bit of data on a computer, a bit being the basic unit of information in computing. Recently, IBM Research announced it can store that same bit of information in just 12 atoms. In order to make the movie atoms were moved with a scanning tunnelling microscope. The microscope weighs two tonnes, operates at minus 268 degrees Celsius and magnifies the atomic surface more than 100 million times :: Read the full article »»»»

Australian beer drinkers will soon have the option of buying a beer with a much longer shelf life, a new type of malt barley, developed by Adelaide researchers and a Japanese brewer, can curb beers propensity of tasting stale when left on the shelf.
The new barley variety ‘SouthernStar’ is the results of collaboration between the University of Adelaide and Sapporo Breweries. Importantly this new barley is not genetically modified, it’s been produced using conventional – albeit high tech – breeding techniques, utilising data from the recently completed Barley Genome Project .
South Australian farmers are to begin commercial production of the barley this year. Commercial crops grown in 2013 will be harvested in November/December, processed into malt in the first half of 2014 and used for commercial beer production in the later part of 2014 :: Read the full article »»»»

REBLOG! via Anna Salleh for Science Online: The simple story we are told about genes being the blueprint of life is “misleading and distorted”, according to a leading science writer. Sixty years ago today, Francis Crick and James Watson published details of the double helix molecular structure of DNA in Nature.
But science writer Dr Philip Ball, who has written a commentary in this week’s Nature, argues the DNA narrative has been oversimplified. Dr Ball is calling for scientists to admit they do not know how evolution works at the molecular level.
“While specialists debate what the latest [genomics] findings mean, the rhetoric of popular discussions of DNA, genomics and evolution remains largely unchanged, and the public continues to be fed assurances that DNA is as solipsistic a blueprint as ever,” Dr Ball wrote in the journal. ”The usual tidy tale of how ‘DNA makes RNA makes protein’ is sanitised to the point of distortion.”
His commentary has raised the hackles of some Australian experts, who defend what has become known as the central dogma of molecular biology. Some years after the landmark paper, Crick articulated the basic idea that “DNA makes RNA, which makes protein”, which ultimately produces an organism’s “observable traits”. But Dr Ball said this narrative is oversimplified :: Read Anna Salleh’s Full Post at ABC News »»»»

Researchers in Melbourne have used a new targeted treatment technique to achieve the highest-ever long-term survival rates for patients with some forms of lung cancer.
The team from Peter MacCallum Cancer Institute used PET/CT - Positron Emission Tomography / Computed Tomography - scans to determine the location and stage of tumours in 76 patients with locally advanced non-small cell lung cancer.
The patients were treated with a combination of radical radiation therapy and chemotherapy, leading to a four year survival rate of 32 per cent, the highest ever published.
Research team leader, Associate Professor Michael MacManus, says that is dramatically higher than the historic average of between 10 and 20 per cent.
PET/CT scanning uses a device which combines both PET and an x-ray Computed Tomography, so that the produced images – taken by both devices sequentially – combine into a single superposed image, a 3D map. The image shows the spatial distribution of metabolic activity in the body can be more precisely :: Read the full article »»»»

Astronomers using a potent NASA space telescope to search for life say they have found planets which are the most Earth-like candidates yet. Two of the five planets orbiting a Sun-like star called Kepler-62 are squarely in the habitable zone – not too hot, not too cold, possibly bearing water – NASA scientists report in the journal Science :: Read the full article »»»»
