Research provides new understanding of genome regulation in early life

After the fertilization of an egg cell, two become one; two sets of genetic information combine to form a genome. We can think of the egg and sperm as information capsules with stored instructions for starting a new life, but post fertilization, what kick starts the interpretation of these instructions?

			Study shows that aging and chronic diseases share common genetic factors The global population aged 60 or over is growing faster than all younger age groups and faces the tide of chronic diseases threatening their quality of life and posing challenges to healthcare and economy systems.

			Genetic testing to be provided by the NHS in exchange for genomic data The NHS is going to start providing genetic tests in exchange for patients in England who agree to share their genomic data so that it can be used for research.

	What is Nutritional Genomics? Since the completion of the human genome project in April 2003, research projects into the effects of diet on the genome have grown exponentially. Nutrition intake is both affected by, and affects, a person’s genes. The ability of the body to take in nutrition, use nutrition effectively, and burn energy in an optimal way can vary greatly between individuals.

	Genetic risk for developing psychiatric disorders or cognitive traits manifest in brain structure from childhood There is only scant scientific evidence available on whether the genetic risk for developing specific psychiatric disorders or cognitive traits is manifest in brain structure from childhood and, to date, studies have focused primarily on adult populations. The question remains unanswered.

	Genetics determine whether you are an early riser or a night owl An international study led by the University of Exeter and Massachusetts General Hospital has shed light on how the workings of the human body clock may be linked to mental health and disease.

	Identical twins shine new light on genetic cause of juvenile arthritis Identical twin toddlers who presented with severe arthritis helped scientists to identify the first gene mutation that can single-handedly cause a juvenile form of this inflammatory joint disease.

	Gene-edited chickens could prevent future flu pandemic British researchers are genetically engineering flu-resistant chickens in an effort to prevent the next deadly human flu pandemic.

	Sleep deprivation linked with DNA damage Sleep deprivation was associated with DNA damage in a new Anesthesia study. In the observational study on 49 healthy full-time doctors who had their blood analyzed at different time points, on-call doctors who were required to work overnight on-site had lower DNA repair gene expression and more DNA breaks than participants who did not work overnight.
