The findings, published today in Human Molecular Genetics, could have considerable impact on women in the UK and other western countries, where many start having children at a later age. Early menopause affects one in 20 UK women.
The study from scientists at the University of Exeter Peninsula Medical School and The Institute of Cancer Research (ICR), funded by The Wellcome Trust, tested four genes associated with the menopause. They compared 2,000 women from the Breakthrough Generations Study who had experienced early menopause with a matched group of the same number. The four genes each affected risk of early menopause. In combination, they had a larger impact, which goes towards explaining why some women experience early menopause.
The Breakthrough Generations Study is a large and comprehensive study into the causes of breast cancer and a partnership between Breakthrough Breast Cancer and the ICR. The study will follow the 100,000 UK women participants for the next 40 years to unravel the lifestyle, environmental and genetic factors that cause the disease.
Although early menopause is associated with a decreased risk of breast cancer, women who experience early menopause are susceptible to other health problems including osteoporosis, cardiovascular disease and a reduction in fertility.
The research could help women determine whether they have a genetic predisposition to early menopause, and therefore predict the time of the end of their reproductive life. They could then make informed family planning decisions on the basis of this knowledge.
Lead scientist Dr Anna Murray, from the University of Exeter Peninsula Medical School, says, "It is estimated that a woman's ability to conceive decreases on average ten years before she starts the menopause. Therefore, those who are destined to have an early menopause and delay childbearing until their 30s are more likely to have problems conceiving.
"These findings are the first stage in developing an easy and relatively inexpensive genetic test which could help the one in 20 UK women who may be affected by early menopause."

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
