Detecting trace amounts of multiple classes of antibiotics in foods

Widespread use of antibiotics in human healthcare and livestock husbandry has led to trace amounts of the drugs ending up in food products. Long-term consumption could cause health problems, but it’s been difficult to analyze more than a few antibiotics at a time because they have different chemical properties. Now, researchers reporting in ACS’ Journal […]

Recent developments in gene editing technology could tempt athletes to change their DNA to get an edge. Now, researchers reporting in ACS’ Analytical […]

Detecting gamma rays with giant perovskite crystals

Gamma ray detection is challenging at the best of times.

The process of detecting gamma rays causes serious damage to those detectors. Researchers have developed a large, self-healing crystal that might help to solve this problem. Gamma rays are the highest energy members of the electromagnetic spectrum. They also have the smallest wavelength, which means that they are quite difficult to detect. A gamma ray […]

Detecting solar neutrinos with the Borexino experiment

Credit: CC0 Public Domain Neutrinos are chargeless particles with about a mass about a millionth that of an electron that are created by the nuclear processes that occur in the Sun and other stars. These particles are often colorfully described as the ‘ghosts’ of the particle zoo because they interact so weakly with matter. A […]

Scientists discover role of protein in detecting the common cold virus

Scientists uncover how a sensor protein activates our immune system against the common cold. The findings may lead to more effective treatments of flu-like symptoms. Image credit: Getty Images The role of a protein in detecting the common cold virus and kick-starting an immune response to fight infection has been uncovered by a team of […]

A Promising Development for Detecting Ocean Productivity

The ocean’s primary productivity—the pace at which organisms photosynthesize organic compounds—is an integral part of the global carbon cycle that affects the cycling of important nutrients and trace metals in marine ecosystems. Ocean primary productivity also controls carbon dioxide exchange between the air and the sea, which in turn affects the concentration of […]

A world record in detecting extremely low levels of gas impurities — ScienceDaily

Photoacoustic spectroscopy applied to background-free analyses was used to measure unprecedentedly small trace gas concentrations. Teemu Tomberg from the University of Helsinki developed detection methods that make it possible to measure extremely small traces of various gases. Why should low concentrations be measured? Trace gases denote substances that occur in very low quantities in air […]
