Preimplantation genetic screening: unvalidated methods discard healthy embryos

11 December 2017 - by Norbert Gleicher

A seemingly brilliant hypothesis of preimplantation genetic screening arose in the 1990s when Dr Yuri Verlinsky proposed using polar body biopsies to detect chromosomal abnormalities in embryos prior to transfer in IVF... Healthy embryos are discarded by unvalidated PGS

Healthy mice created from eggs and sperm without conventional fertilisation

19 September 2016 - by Paul Waldron

Unfertilised mouse egg cells that have been made to divide can develop into healthy offspring by the injection of sperm, according to a new study... [Read More]

Embryonic stem cell production breakthrough achieved in mice

31 March 2014 - by Dr Lanay Griessner

A technique to generate mouse embryonic stem cells could, if repeated in human cells, improve access to stem cells by using fertilised eggs that would previously have been discarded... [Read More]

Depression may speed up DNA ageing

18 November 2013 - by María Victoria Rivas Llanos

Severe depression speeds up the ageing process of our cells, researchers have found... [Read More]

Faulty gene leading to skin disorder spotted

22 October 2012 - by Dr Nicola Davis

Scientists have identified a gene involved in an incurable skin disease. Using advanced screening techniques they discovered several mutations in this gene in people with punctuate palmoplantar keratoderma (PPK)... [Read More]

Aggressive brain cancer linked to gene fusion

30 July 2012 - by Dr Zara Mahmoud

Some cases of glioblastoma - a particularly aggressive form of brain cancer - may be due a genetic mutation where two separate genes fuse into one, scientists report... [Read More]

An eggsample of why it is hard to prove a negative

30 July 2012 - by Professor Robin Lovell-Badge

Earlier this year, a paper claimed to have found cells, called ovarian stem cells, in the adult ovaries of both mice and humans. These cells could apparently be grown in large numbers in the lab and could retain the ability to give rise to eggs. A new study finds no evidence for the existence of germline progenitors able to produce eggs in postnatal ovaries. Is a lack of evidence sufficient to win the argument?... [Read More]

By accident, scientists discover how commonest DNA replication error is corrected

15 May 2012 - by Dr Lux Fatimathas

Scientists have discovered the enzyme in our cells which corrects the most frequently occurring mistake in DNA as cells divide... [Read More]

Common cancer gene may change chromosome numbers

22 August 2011 - by Heidi Colleran

Two US studies published this week have shed light on how a gene mutation can change the number of chromosomes present in the cells of more than 90 percent of cancers... [Read More]

Cell division genes published

06 April 2010 - by Ailsa Stevens

The results of a huge multinational project to pinpoint all the genes and related proteins essential for cell division are to be made publically available for other researchers to use... [Read More]

Defining the human embryo: A way with words?

05 July 2006 - by Professor Martin H Johnson

In February this year, the Australian National Health and Medical Research Council (1) published a discussion paper entitled: 'Human Embryo - A biological definition'. This publication provides an authoritative and comprehensive summary of the scientific arguments and experiments that bear on our understanding of what a human embryo is and is... [Read More]
