Giant squid a single global species

John Kerr posted in on March 22nd, 2013.

A new study comparing the DNA of a giant squid held at Te Papa with samples from 42 of its relatives from around the globe has revealed that mysterious sea creatures comprise a single, yet extremely spread out, species. Very little is known about the enigmatic giant squid, with most of our knowledge gleaned from […]

UK scientists start checks on safety of mitochondrial swaps for human babies

Kent posted in on January 20th, 2012.

Biotech regulators in Britain have started public consultation on experimental reproductive procedures proposed to treat rare mitochondrial diseases, and scientists have been given 5.8 million pounds ($NZ11.1m) to investigate the safety of the techniques. And the  Nuffield Council on Bioethics is conducting an ethical review on the imnplications of the DNA-swapping technologies, which involve transferring […]

Ash means empty skies over Britain Thousands of travellers are feeling the effects of a large volcanic eruption in Iceland, with flights across Europe cancelled as ash floats across Britain and the continent. The impact on travel plans is illustrated well in this graphic that ran in The Guardian. Scientists meanwhile have been analysing every […]

DNA transfer prevents mitochondrial disease in humans

Peter Griffin posted in on April 15th, 2010.

AusSMC: In a world-first study to be published in Nature, scientists have shown in human embryos a new technique developed last year in monkeys to treat maternally-inherited mitochondrial diseases. The study describes the first ever transfer of genetic material between fertilised human eggs which has the potential to ‘treat’ human mitochondrial DNA (mtDNA) disease at […]
