CERN Physicists Measure High-Energy Neutrino Interaction Strength
The Forward Search Experiment (FASER) at CERN’s Large Hadron Collider (LHC) is designed to search for extremely weakly interacting particles. Such particles are predicted by many theories beyond the Standard Model that are attempting to solve outstanding problems in physics such as the nature of dark matter and the matter-antimatter imbalance in the Universe. Another
Physicists find a new way to measure the properties of a material’s surface layer
Using a process called auger-mediated positron sticking (AMPS), scientists from the Positron Lab in the UTA Department of Physics have developed a new technique that can measure the properties of the topmost atomic layer of materials. This novel spectroscopic tool uses virtual photons to measure the topmost atomic layer’s electronic structure selectively. When incoming positrons
Scientists Measure Sediment Bloom Created By Deep Sea Mining
Scientists have measured the sediment bloom left in the wake of a deep sea mining vehicle as it went about its operations. The team of MIT ocean scientists conducted their 2021 study in the Clarion Clipperton Zone (CCZ) in the Pacific Ocean. The team equipped a prototype to take samples and monitor the plumes caused
New method to measure the cosmic microwave background’s temperature
The cosmic microwave background (CMB) is leftover electromagnetic radiation from the earliest cosmological epoch, i.e., Big Bang. It gives a snapshot of the early Universe. Over the past two decades, measurements of the cosmic microwave background’s temperature have provided profound insight into the nature of the Universe. Detailed information about the composition and evolution of…
Video: How to measure blood pressure using an automatic monitor
To monitor your blood pressure using an automatic blood pressure monitor, find a comfortable place to sit with good back support at a table or desk. When you're ready to take your blood pressure, sit quietly for three to five minutes beforehand. Place your feet flat on the floor and rest your arm on a…
New biosensors measure toxic drugs in cancer, arthritis, and organ transplant patients
Researchers are a step closer to transforming a US$70 billion global diagnostic industry with new designer biosensors that 'switch on' colour or electrical responses to drugs used in cancer, arthritis, and organ transplant treatment.

The isotope tin-100 is of interest for nuclear structure due to its closed-shell proton and neutron configurations. It is also the heaviest nucleus comprising protons and neutrons in equal numbers. In new research, physicists from the ISOLTRAP experiment at CERN’s Isotope mass Separator On-Line (ISOLDE) facility performed direct mass measurements of indium-99 and indium-100, neighboring…
