US Scientists Clone Human Embryos

Posted: May 16th, 2013 | Author: | Filed under: Applied Science, Genetics | Tags: , , , | Comments Off on US Scientists Clone Human Embryos

OHSU Stem Cell breakthrough Cankler Science NewsScientists 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 »»»»


Breakthrough Cancer Treatment Improves Survival Rates

Peter MacCullum Cancer InstituteResearchers 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 »»»»


Tow Me To The Moon

Tow Me To the MoonThat last bastion of US ingenuity, NASA will apparently launch a new space mission that intends to grab a small asteroid and tow it into orbit around the moon, as part of a long-range plan towards establishing permanent manned outposts in space.

US Senator Bill Nelson says to get the project off the ground, president Barack Obama will propose around $US100 million for the space agency in his 2014 budget, which he submits to Congress this week.

The proposed plan calls for a robotic-spacecraft to capture an asteroid and tow it back towards Earth, ultimately leaving it in a stable orbit around the moon.

Once there there could be mining activities, research into ways of deflecting an asteroid from striking Earth, and testing to develop technology for a trip to deep space and Mars, Senator Nelson said in his statement :: Read the full article »»»»


Extinct Gastric Brooding Frog Brought Back From Extinction

Posted: March 18th, 2013 | Author: | Filed under: Applied Science, Biology | Tags: , , , , , | Comments Off on Extinct Gastric Brooding Frog Brought Back From Extinction

Gastic Brooding Frog

A frog that can swallow its eggs, brood its young in its gut and give birth through its mouth. The gastric Brooding Frog has been extinct for more than 30 years ago, but the extraordinary amphibian is about to be un-extinct.

In a world first, a team of Australian scientists has taken the first major step in bringing it back to life. They have successfully reactivated its DNA and produced a viable embryo.

The scientists located a frozen carcasses and have been able to recover tissue from the Gastric Brooding Frog. Using a technique known as SCNT, somatic cell nuclear transfer – creating a clone embryo with a donor nucleus – they implanted the long-dead cell nucleus from the extinct species into a fresh egg from related frog :: Read the full article »»»»


Australian Health Authorities on the Lookout for SARS Like Virus

Posted: February 16th, 2013 | Author: | Filed under: Medicated | Tags: , , , | Comments Off on Australian Health Authorities on the Lookout for SARS Like Virus

Coronaviris NCoVAustralian authorities are watching a virus, which has killed almost half of the people who have contracted it, as it spreads across the Middle East and Europe. The World Health Organisation first identified novel coronaviris (NCoV) in September, but experts say there is no signs of it in Australia.

The virus is part of the same disease family as Severe Acute Respiratory Syndrome – SARS –  A total of 11 people have contracted NCoV in Britain, Germany, Saudi Arabia and Jordon. Five sufferers have died.

Between November 2002 and July 2003, an outbreak of SARS in Hong Kong came close to being classified a pandemic, with 8,273 cases and 775 deaths worldwide – 9.5 per cent fatality – according to the World Health Organization. Within weeks, SARS spread from Hong Kong to infect individuals in 37 countries.

University of Queensland virology professor Paul Young says local health authorities are on alert because there is evidence of person-to-person transmission :: Read the full article »»»»
