A new study shows a deep connection between some of the largest, most energetic events in the universe and much smaller, weaker ones powered by our own Sun.

The results come from a long observation with NASA’s Chandra X-ray Observatory of Abell 2146, a pair of colliding galaxy clusters located about 2.8 billion light-years from Earth. The new study was led by Helen Russell from the School of Physics and Astronomy at the University of Nottingham.

Galaxy clusters contain hundreds of galaxies and huge amounts of hot gas and dark matter and are among the largest structures in the universe...

Study offers a new approach in the care of allergy sufferers. Micronutrient deficiencies can promote inflammation and render the immune system particularly sensitive to allergenic substances. In particular, iron deficiency signals danger to immune cells and leads to a more pronounced, exaggerated immune response. For the first time, scientists at the Messerli Research Institute of MedUni Vienna, Vetmeduni Vienna and the University of Vienna conducted a placebo-controlled trial and showed that targeted dietary measures can reduce the symptom burden in allergic reactions. The researchers are therefore treading a completely new path in the care of allergy sufferers. The study was recently published in The Journal of Allergy and Clinical Immunology: In Practice.

The background to the s...

A team of physicists has found a way to operate mass manufacturable photonic sensors at the quantum limit. This breakthrough paves the way for practical applications such as monitoring greenhouse gases and cancer detection.

Sensors are a constant feature of our everyday lives. Although they often go unperceived, sensors provide critical information essential to modern healthcare, security, and environmental monitoring. Modern cars alone contain over 100 sensors and this number will only increase.

Quantum sensing is poised to revolutionise today’s sensors, significantly boosting the performance they can achieve...

Research team studies kombucha cultures under simulated extraterrestrial conditions. An international research team including the University of Göttingen has investigated the chances of survival of kombucha cultures under Mars-like conditions. Kombucha is known as a drink, sometimes called tea fungus or mushroom tea, which is produced by fermenting sugared tea using kombucha cultures – a symbiotic culture of bacteria and yeast. Although the simulated Martian environment destroyed the microbial ecology of the kombucha cultures, surprisingly, a cellulose-producing bacterial species survived. The results were published in Frontiers in Microbiology.

The scientists of the “Biology and Mars Experiment” (BIOMEX) project had already sent kombucha cultures to the International Space Statio...
