Until now, de novo genetic mutations, alterations in a gene found for the first time in one family member, were believed to be mainly the result of new mutations in the sperm or eggs (germline) of one of the parents and passed on to their child.

Researchers from The Netherlands have now succeeded in determining that at least 6.5% of de novo mutations occur during the development of the child (post-zygotic) rather than from the germline of a parent.  

A daily sugar-sweetened beverage habit may increase the risk for non-alcoholic fatty liver disease (NAFLD).

Elon Musk, and NASA both have in mind the idea of doing interplanetary voyages straight away, aiming for Mars, with Obama going so far as to say about the Moon: “But I just have to say pretty bluntly here: We’ve been there before.”. If you hold that view, you are undoubtedly in distinguished company.

Now - there are two things here - yes we've been to the Moon before - but is that the end of all interest in it? But first - how ready are we for interplanetary voyages? 

Patient safety, whistleblowing and public inquiry have a long historical legacy - but with mixed results.

Yet lessons from the past can inform current medical practice and help maintain a safe environment for patients and that will be the topic addressed by 20 health organizations who will be convening at the University of Leicester on June 11th to discuss how old patterns of patient safety and historical complaints against doctors are still being replicated in the modern welfare system – and what lessons can be learned by looking to our medical past. 

The General Medical Council (GMC) has launched a consultation this year, which will place patient safety at the heart of medical education and training across the UK.

For being so small, fruit flies have had a large impact on genetic research. Thomas Werner, an assistant professor of biological sciences at Michigan Technological University, has bridged the miniscule and the massive in an effort to better understand the mechanisms behind several unique features of fruit fly genes.

Over the past week, several studies that Werner co-authored have been published in PLoS ONE, the Proceedings of the National Academy of Sciences, and Nature Education. All are linked by Drosophila--a genus of fruit flies--and the insights that fruit fly genetics provide on human health, specifically cancer-causing genes.

A case study reports on a young woman who gave birth to a healthy child after doctors restored her fertility by transplanting ovarian tissue that had been removed and frozen while she was a child. 

There have been reports of successful pregnancies after ovarian transplantation using tissue that had been removed from patients as adults but this is the first successful instance using tissue taken from girls before puberty.

The Global Sanitation Fund's latest Progress Report details how support for nationally-led programs has helped 7 million people in over 20,500 communities become open-defecation free, improved toilets for 4.2 million people and seen eight million people gain access to hand-washing facilities. The governments of Australia, Finland, the Netherlands, Sweden, Switzerland and the United Kingdom contributed.

Established by WSSCC, the GSF funds large-scale behavior change activities to help poor people in the world's hardest-to-reach areas attain safe sanitation and adopt good hygiene practices. The community-led, government-backed activities support existing national efforts, uniting a diverse group of stakeholders to address deficiencies in access to sanitation and hygiene.

Bariatric surgery does not only benefit the health of patients who undergo this weight loss procedure. It also leads to greater intimacy between them and their life partners, and adds a spark to their sex life. It's all in all a shared journey that brings partners closer together, says Mary Lisa Pories of East Carolina University in the US, lead author of a study providing insights into the experience of couples after one of the partners underwent weight loss surgery. The findings are published in Springer's journal Obesity Surgery.

Much media attention is being given to the rising toll of methamphetamine-related harm in Australia, fuelled by the increased availability and use of high purity crystalline methamphetamine (crystal meth or ice).

Unlike other forms of methamphetamine available in Australia (speed or base), ice (crystalline methamphetamine or crystal meth) can be smoked. This gives a rapid drug effect because it gets into both the bloodstream and the brain quite quickly.

A single dose of the bivalent human papillomavirus (HPV) vaccine (Cervarix) offers a similar level of protection against the HPV-16/18 infections - which cause about 70% of cervical cancers - as current two- and three-dose schedules, according to data from two large phase 3 trials.

Worldwide, cervical cancer is the fourth most common cancer in women. The bivalent vaccine targets HPV types 16 and 18 that are responsible for about 70% of cervical cancers. The HPV-16/18 vaccine was initially approved to be given in three doses over 6 months, but many countries are moving to a two-dose schedule in adolescents.
