Proton Therapy Lowers Risk of Side Effects in Cancer compared to Traditional Radiation

Penn researchers have demonstrated that proton therapy reduces the likelihood of adverse affects among cancer patients also being treated with chemotherapy. The study compared proton therapy patients to those receiving traditional photon radiation. SOURCE/PERELMAN SCHOOL OF MEDICINE

Study found protons led to two-thirds reduction in unplanned hospitalizations. Proton therapy leads to significantly lower risk of side effects severe enough to lead to unplanned hospitalizations for cancer patients when compared with traditional radiation, while cure rates between the two groups are almost identical...

New Nano-barrier for Composites could Strengthen Spacecraft Payloads

Stress modelling within CFRP and coated components. Credit: Nature Materials (2019). DOI: 10.1038/s41563-019-0565-3

The University of Surrey has developed a robust multi-layed nano-barrier for ultra-lightweight and stable carbon fibre reinforced polymers (CFRPs) that could be used to build high precision instrument structures for future space missions.

CFRP is used in current space missions, but its applications are limited because the material absorbs moisture. This is often released as gas during a mission, causing the material to expand and affect the stability and integrity of the structure. Engineers try to minimise this problem with CFRP by performing long, expensive procedures such as drying, recalibrations and bake-out- all of which may not completely resolve the issue.

The development of technologies which can process information based on the laws of quantum physics are predicted to have profound impacts on modern society. For example, quantum computers may hold the key to solving problems that are too complex for today’s most powerful supercomputers, and a quantum internet could ultimately protect the worlds information from malicious attacks...

The Coolest LEGO in the universe

the Lego
The LEGO ® figure and block used in the experiment

For the first time, LEGO has been cooled to the lowest temperature possible in an experiment which reveals a new use for the popular toy. Its special properties mean it could be useful in the development of quantum computing.

A world leading team of ultra-low temperature physicists at Lancaster University decided to place a LEGO figure and four LEGO blocks inside their record-breaking dilution refrigerator.

This machine – specially made at the University – is the most effective refrigerator in the world, capable of reaching 1.6 millidegrees above absolute zero (minus 273.15 Centigrade), which is about 200,000 times colder than room temperature and 2,000 times colder than deep space.

The results – published in the journal Scientific R...
