A condition linked to heart disease, diabetes, high blood pressure and obesity
For over a decade, scientists have known that insulin resistance - a syndrome where the body does not respond as well as it should to insulin - is linked to the development of heart disease, diabetes, high blood pressure, obesity and polycystic ovary syndrome. In fact, one in four adult Americans has insulin resistance, with Mexican Americans having the highest prevalence. But because people with insulin resistance are so likely to develop diseases such as diabetes and heart disease, scientists have turned their attention on investigating whether a common gene abnormality may be involved.
Now, researchers at Cedars-Sinai Medical Center, in collaboration with investigators at UCLA, have found that lipoprotein lipase (LPL), a gene that controls the delivery of fatty acids to muscle and tissues in the body, is linked to insulin resistance in Mexican-Americans. Their findings, reported in the January issue of Diabetes, may enable scientists to design therapies that target LPL to prevent insulin resistance, a condition estimated to affect over 80 percent of the 16 million Americans with Type 2 diabetes, and additional millions at risk for heart disease.

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...
