Nanoscale NMR spectroscopy

4603 days ago

Nuclear magnetic resonance spectroscopy is now possible on nanoscale samples, without having to cool them to near absolute zero.

Future applications could include imaging single molecules inside living cells and examining the structure of proteins, which would help in the study of disease and development of new drugs.

Obesity associated with smaller brain volumes

4605 days ago

Scientists at Uppsala University have found that elderly obese patients have smaller brains.

292 elderly Swedish patients were examined using MRI. Those who were obese had 1.5% smaller total brain volumes and reduced total gray matter volume.

The results may provide evidence for cognitive suppression of appetite that may lower the risk of developing obesity in later life.
