How our brains track where we and others go
As COVID cases rise, physically distancing yourself from other people has never been more important. Now a new UCLA study reveals how your brain navigates places and monitors someone else in the same location.
Published Dec. 23 in Nature, the findings suggest that our brains generate a common code to mark where other people are in relation to ourselves. We studied how our brain reacts when we navigate a physical space - first alone and then with others, said senior author Nanthia Suthana, the Ruth and Raymond Stotter Chair in Neurosurgery and an assistant professor of neurosurgery and psychiatry at the David Geffen School of Medicine at UCLA and Jane and Terry Semel Institute for Neuroscience and Human Behavior.

With the launch of the COVID-19 vaccination campaign, officials expect to see a surge in the number of potential bad vaccine reactions. Their job will be to find out how real those reactions are finding a signal in the noise.
If previous vaccine reports are a guide, the vast majority of the reports won’t end up being real safety issues. But federal officials encourage physicians, especially those who don’t usually give vaccines, to tell the programs about any hint of an issue because they want to make sure they know about and thoroughly investigate everything.

A tube that is slipped inside the nostrils to dull the sense of smell could offer a simple and drug-free way to lose weight.
People who used the device daily for three months while on a strict diet shed twice as much weight as a second group, who dieted alone.
They also ate fewer sweets, and drank fewer soft drinks and less alcohol, according to a new study in the journal Obesity Facts.
It is thought that by directing air that’s inhaled through the nostrils away from the smell centre of the nose, the 2.5cm-long hollow tube prevents smells from stimulating appetite.
