Sedentary Behavior Independently predicts Cancer Mortality

Replacing sitting time with 30 minutes of activity associated with lower risk of cancer death. In the first study to look at objective measures of sedentary behavior and cancer mortality, researchers from The University of Texas MD Anderson Cancer Center found that greater inactivity was independently associated with a higher risk of dying from cancer. The most sedentary individuals had an 82% higher risk of cancer mortality compared to the least sedentary individuals. An accelerometer was used to measure physical activity, rather than relying on participants to self-report their activity levels

“This is the first study that definitively shows a strong association between not moving and cancer death,” said Susan Gilchrist, M.D...

Graphene Smart Textiles developed for Heat Adaptive Clothing

Graphene Smart Textiles The University of Manchester
Using electro-optical tunability of graphene, adaptive optical textiles were made with electrically controlled reflectivity and emissivity covering the infrared and near-infrared wavelengths.

New research on the two-dimensional (2D) material graphene has allowed researchers to create smart adaptive clothing which can lower the body temperature of the wearer in hot climates.

A team of scientists from The University of Manchester’s National Graphene Institute have created a prototype garment to demonstrate dynamic thermal radiation control within a piece of clothing by utilising the remarkable thermal properties and flexibility of graphene. The development also opens the door to new applications such as, interactive infrared displays and covert infrared communication on textile.

“Unexpected” Events have been Detected at the world’s most Sensitive Dark Matter Experiment.

Unusual behaviour could require new physics to be explained

Researchers do not claim to have found dark matter, but they say that there is an as yet unexplained and unexpected rate of events found in data from the experiment, and that they do not know the source.

The new breakthrough could be a sign of an entirely newly discovered kind of particle, or unpredicted behaviour that may require us to fundamentally change our understanding of physics.

The results come from the XENON collaboration, which brought together researchers from across the world who were attempting to detect dark matter. It did so using an experiment known as XENON1T, which was located deep underground in Italy.

Seeing evidence of dark matter would be one of the biggest possible breakthroughs in science...

Light-activated ‘CRISPR’ Triggers Precision Gene Editing and Super-fast DNA Repair

In a series of experiments using human cancer cell lines, scientists at Johns Hopkins Medicine say they have successfully used light as a trigger to make precise cuts in genomic material rapidly, using a molecular scalpel known as CRISPR, and observe how specialized cell proteins repair the exact spot where the gene was cut.

Results of the experiments, published June 11 in Science, not only reveal new details about the DNA repair process, but also are likely, the researchers say, to speed up and aid understanding of the DNA a...
