What loneliness looks like in the brain
Neural "signature" may reflect how we respond to feelings of social isolation This holiday season will be a lonely one for many people as social distancing due to COVID-19 continues, and it is important to understand how isolation affects our health. A new study shows a sort of signature in the brains of lonely people that make them distinct in fundamental ways, based on variations in the volume of different brain regions as well as based on how those regions communicate with one another across brain networks.

'Boss' genes could save human hearts - and the reef
’Boss’ genes could save human hearts - and the reef
The chain of command inside human cells is similar to the way a factory is run, two University of Queensland researchers say. But Dr Nathan Palpant and Associate Professor Mikael Boden 's big news is that they have found the password to the chief executive's computer - metaphorically speaking. "We discovered a simple but powerful rule revealing how cells are controlled by rare decision-making genes,' said Dr Palpant, from UQ's Institute for Molecular Bioscience.

Gene could help predict response to cervical cancer treatment
FINDINGS UCLA researchers have identified a potential diagnostic marker that could help predict how likely someone with cervical cancer is to respond to the standard treatment of chemotherapy and radiation. The scientists found that PACS-1, a gene that resides on a small segment of the long arm of chromosome 11, is overexpressed in cancer tissues, which can result in cancer growth and spread.

Tagging, recording and replaying neural activity
An interdisciplinary team of scientists has created a new molecular tool to help us better understand the cellular basis of behavior. A new molecular probe from Stanford University could help reveal how our brains think and remember. This tool, called Fast Light and Calcium-Regulated Expression or FLiCRE (pronounced "flicker"), can be sent inside any cell to perform a variety of research tasks, including tagging, recording and controlling cellular functions.

New treatment could spare early-stage rectal cancer patients life-altering side effects
A new and less invasive treatment developed by Cancer Research UK researchers is safer than standard major surgery for early-stage rectal cancer, giving patients a better quality of life with fewer life-altering side effects, results from a pilot study show. Results from the TREC trial show that a combination of local keyhole surgery and radiotherapy, rather than major surgery that removes the whole rectum, prevents debilitating side effects, such as diarrhoea, or the need for a permanent colostomy bag.
