Professor Lance Lanyon, Principal of The Royal Veterinary College, Karla Lee, Helen Jessop, Rosemary Suswillo, Gul Zaman from the Department of Basic Sciences at The Royal Veterinary College have shown in their research that the Estrogen Receptor has a fundamental role in bone cells by adjusting the bone architecture to match the loads individuals place on them. Their paper is published in the latest edition of Nature.
The strain imposed by mechanical loading on bone tissue normally stimulates a response by bone cells that results in an adjustment to bone architecture and enables the bone to withstand reasonable loads. This research centred on why this process should become less effective in some 50 per cent of post-menopausal women who suffered fractures as a result.
This research shows why estrogen withdrawal results in bone loss – the number of Estrogen Receptors is reduced by the estrogen levels. When estrogen levels decline (as at menopause) ER levels also decline to the extent that they limit the bone cells’ adaptive responses to load bearing thus producing an effective environment of disuse or underuse which permits bone loss.

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...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
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...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
