For The First Time, Scientists Have Performed Atom Interferometry in Space


For The First Time, Scientists Have Performed Atom Interferometry in Space
14 APRIL 2021
To make some of the most precise measurements we can of the world around us, scientists tend to go small - right down to the atomic scale, using a technique called atom interferometry.
 
Now, for the first time, scientists have performed this kind of measurement in space, using a sounding rocket specially designed to carry science payloads into low-Earth space.
It s a significant step towards being able to perform matter-wave interferometry in space, for science applications that range from fundamental physics to navigation.
We have established the technological basis for atom interferometry on board of a sounding rocket and demonstrated that such experiments are not only possible on Earth, but also in space, said physicist Patrick Windpassinger of Johannes Gutenberg University Mainz in Germany. ....

General Atomics: Diazyme Laboratories, Inc. Announces CE-IVD for its Semi-Quantitative SARS-CoV-2 Neutralizing Antibody Test


General Atomics: Diazyme Laboratories, Inc. Announces CE-IVD for its Semi-Quantitative SARS-CoV-2 Neutralizing Antibody Test
SAN DIEGO, April 01, 2021 (GLOBE NEWSWIRE) Diazyme Laboratories, Inc. announced March 30th that it has obtained CE-IVD marking for its SARS-CoV-2 neutralizing antibody test. The Diazyme test is a high throughput chemiluminescent immunoassay with excellent correlation to a fluorescence based neutralization assay, which has been used to evaluate the adaptive immune response in vaccine studies
1. Diazyme also announced plans to work with US FDA for EUA application.
Unlike the widely available total SARS-CoV-2 IgG antibody tests, Diazyme s neutralizing antibody test measures the subset of neutralizing antibodies that block the interaction between the receptor binding domain (RBD) of the viral spike glycoprotein and the human ACE2 cell surface receptor. The Diazyme neutralizing antibody test gives the scientific community and health authorities a v ....

A Decades-Long Quest Reveals New Details of Antimatter


To revist this article, visit My Profile, then View saved stories.
It often goes unmentioned that protons, the positively charged matter particles at the center of atoms, are part antimatter.
We learn in school that a proton is a bundle of three elementary particles called quarks two “up” quarks and a “down” quark, whose electric charges (+2/3 and −1/3, respectively) combine to give the proton its charge of +1. But that simplistic picture glosses over a far stranger, as-yet-unresolved story.
