Adult children of mothers with Alzheimer's at increased risk

A family history of Alzheimer's disease significantly increases the risk for developing this disorder, but a new study in Biological Psychiatry suggests that which of your parents has the disease is very important.

Genomic imprinting can influence carrier's selfish or altruistic behavior

If you are more inclined to love thyself than thy neighbor, it could be your mother's fault. Those are the findings of Francisco -beda, assistant professor of ecology and evolutionary biology at the University of Tennessee, Knoxville.-beda, along with fellow evolutionary biologist Andy Gardner from Oxford University, examined the impact that genomic imprinting has on the carrier's selfish or altruistic behavior.

New findings may allow clinicians to prevent complications in pregnancy

Researchers at Mount Sinai School of Medicine have found that epigenetic marks on human placentas change from the first trimester of pregnancy to the third, a discovery that may allow clinicians to prevent complications in pregnancy.

Analysis suggests human development is set by ongoing interplay of parent and offspring genes

An analysis of rare genetic disorders in which children lack some genes from one parent suggests that maternal and paternal genes engage in a subtle tug-of-war well into childhood, and possibly as late as the onset of puberty.

Prader-Willi syndrome - new genetic clues

A new mouse model for a genetic cause of obesity has been developed by scientists at the Stanford University School of Medicine and Lucile Packard Children's Hospital.

Not just humans benefit from animal biotechnology

Laboratory animals are the source of major discoveries and breakthroughs in biology, not just in tackling disease but also unravelling fundamental molecular processes.

Researchers replace organ in mice using 'single-parent' stem cells

Researchers at the University of Pennsylvania School of Veterinary Medicine have derived uniparental embryonic stem cells - created from a single donor's eggs or two sperm - and, for the first time, successfully used them to repopulate a damaged organ with healthy cells in adult mice.

New genetic theory of parental teamwork

A molecular 'battle of the sexes' long considered the major driving force in a baby's development is being challenged by a new genetic theory of parental teamwork.

In vitro fertilisation could be causing genetic errors in embryo

The conditions in which embryos are cultured in the laboratory during in vitro fertilisation could be causing genetic errors that are associated with certain developmental syndromes and other abnormalities in growth and development, such as low birth weight.

The role of evolutionary genomics in the development of autism

Scientists at the London School of Economics, UK and Simon Fraser University, Canada have described the first hypothesis grounded in evolutionary genomics explaining the development of autism.

Exploiting biology's own chemical toolbox...

Exploiting biology's own chemical toolbox, researchers have developed a new technique that will allow them to modify specific sequences within a DNA molecule. The approach will not only help reveal the impact of biochemical alterations to DNA, but could have far-reaching implications for DNA-based medical diagnosis and nanobiotechnology.

Common epigenetic problem doubles cancer risk

In experiments with mice, a team of scientists from the United States, Sweden and Japan has discovered that having a double dose of one protein is sufficient to change the normal balance of cells within the lining of the colon, thereby doubling the risk that a cancer-causing genetic mutation will trigger a tumor there.

New genetic hypothesis for the cause of autism

Researchers have proposed a new hypothesis on the cause of autism, suggesting a mixed epigenetic and genetic and mixed de novo and inherited (MEGDI) model.
