Study suggests hope for better treatment of Alzheimers and stroke
Until now, scientists have been unable to distinguish between dementia caused by Alzheimers disease and that caused by poor blood flow to the brain. But, researchers at the San Francisco VA Medical Center have now used a combination of magnetic resonance imaging (MRI) and a related technique knows as MR spectroscopy to differentiate between the two kinds of dementia. Their work offers hope of improving the treatment of dementia in patients with poor blood flow, such as stroke victims, and the testing of drugs to treat Alzheimers disease (AD).
"Currently, there are no effective treatments for Alzheimers disease, but we do have options for treating vascular disease. So, being able to determine that there is a vascular component to a patients dementia would make a big difference in planning for treatment," said Norbert Schuff, PhD, a researcher in the Magnetic Resonance Unit at the San Francisco VA Medical Center and a UCSF associate professor of radiology.

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.

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...
