A form of beta blocker, a drug commonly used to lower blood pressure and ward off repeat heart attacks, may provide the answer to preventing osteoporosis, said a Baylor College of Medicine researcher.
In a report that appears online today in the journal Nature, Dr. Gerard Karsenty, BCM professor of molecular and human genetics, and his colleagues demonstrate in mice that the sympathetic nervous system mediates the resorption or destruction of bone through a special receptor on bone cells, and that this effect is required for the development of osteoporosis after menopause in mice. Preventing the sympathetic nervous systems from activating this receptor could prevent osteoporosis.
An estimated 10 million Americans over the age of 50 and 30 million people worldwide have osteoporosis, a disease in which there is less bone mass and a high risk of fracture. Each year, 1.5 million Americans suffer a fracture because of the disease. In a report last October, the U.S. Surgeon General estimated that the cost of caring for people with osteoporosis-related fractures totals $18 billion per year, a figure that will increase unless prevention efforts improve.

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...

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...
