A team of researchers at the University of Ottawa and its Nexus for Quantum Technologies Institute, in collaboration with researchers from Federico II University in Italy, has developed a programmable quantum simulator that shapes a beam of light to replicate how particles move through complex materials, avoiding the need for ever-larger electronic hardware.
Ready meals containing fish and seafood can expose consumers to chemical contaminants that are present in the environment or introduced during processing and packaging. A study by the Universitat Rovira i Virgili (URV) has, for the first time, analyzed the presence of a wide range of high-volume chemical substances in ready-made fish and seafood dishes sold in Tarragona, Spain.
Modern life depends on quantum physics. It makes technologies such as GPS navigation, MRI scanners and computer chips possible. Now, the same science may also lead to a new way to test the health of our eyes. A University at Buffalo-led team has used a technique from quantum optics to make a little-known visual pattern produced inside the eye easier to see—potentially opening the door to a new way to test retinal health.
Two explosions in the Syrian capital earlier this week came as French President Emmanuel Macron was visiting.
Syrian authorities say they have arrested the cell responsible for recent bombings in Damascus and the suspects are affiliated with ISIL (ISIS).
When Iran faced an all-out war against the United States and Israel, Tehran did not respond with missiles and drones alone; it shut down the Strait of Hormuz, a vital waterway for global energy.
Five Guatemalan nationals have now plead guilty in the migrant smuggling case linked to the deaths of 55 migrants.
Two more Guatemalan men have pleaded guilty in the United States to charges related to a human smuggling operation that resulted in a 2021 truck crash in southern Mexico, killing 55 migrants.
A single monitoring network developed by McGill, Natural Resources Canada, Université du Québec à Montréal (UQAM) and Dalhousie University researchers can simultaneously track earthquakes, water behavior, human activity and whales, providing a comprehensive picture of what's happening in, under and far from the water. The research is published in the journal Seismica.
