Unraveling invisible particles: Physicists use water to detect neutrinos

Detection of neutrinos from nuclear reactors with water

The SNO+ detector at a depth of 2 kilometers in a mine in Ontario, Canada. The image shows the ropes holding the 12 m diameter acrylic vessel filled with 1,000 tons of water and the light sensors that detect a small amount of light from neutrino interactions.

Share on PinterestHealth data from smartwatches could aid in early diagnosis of Parkinson’s disease. Dimensions/Getty Images A recent study explored the use of wrist accelerometers to detect Parkinson’s disease prior to clinical diagnosis. Researchers have found that a decrease in the speed of movement could be observed several years before a person is diagnosed with … Read more

Did the Pulsar Timing Array actually detect colliding primordial black holes?

Universe Today

The universe is filled with gravitational waves. We know this thanks to the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), which recently announced the first observations of long-wavelength gravitational waves rippling through the Milky Way. The waves are likely caused by supermassive black hole mergers, but can we prove it? Most of the gravitational … Read more

Flying skydivers leads geneticist Clemson to develop a system to detect DNA in the sky

July 5, 2023July 5, 2023 As she flew through a Saharan dust plume above Anderson while piloting skydivers to their jump altitude, Clemson University geneticist and licensed commercial pilot Kimberly Mtris saw a research opportunity literally before her eyes. The atmosphere was saturated with particulate matter as transcontinental clouds of dust and sand swirled … Read more
