Research from Australia in this week’s issue of THE LANCET suggests that tall girls given oestrogen therapy in adolescence to reduce adult height are more likely to experience later fertility problems than the general population.
Treatment with oestrogen to reduce the adult height of tall girls has been available since the 1950s. No randomised trials have examined the effect of oestrogen therapy. Such therapy alters the development of the long bones and has been reported to reduce adult height by 2–10 cm.
In a retrospective cohort study, historical data from paediatric endocrinologists and self-referrals identified around 1400 women who were assessed for oestrogen therapy from 1959 onwards. 780 of these women completed a survey about their fertility in later life, half of whom actually received therapy (the treatment group); the other half were assessed but not given hormone treatment (the control group).

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
