No more needles for diagnostic tests? Nearly pain-free microneedle patch can test for antibodies and more in the fluid between cells — ScienceDaily

Blood draws are no fun. They hurt. Veins can burst, or even roll — like they’re trying to avoid the needle, too. Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial infection, such as SARS-CoV-2, the virus responsible for COVID-19; or cytokines indicative of inflammation seen […]

Record-breaking laser link could help us test whether Einstein was right — ScienceDaily

Scientists from the International Centre for Radio Astronomy Research (ICRAR) and The University of Western Australia (UWA) have set a world record for the most stable transmission of a laser signal through the atmosphere. In a study published today in the journal Nature Communications, Australian researchers teamed up with researchers from the French National Centre […]

Point-of-care test developed for tumor marker in human saliva based on lanthanide nanoprobes

Schematic illustration of CEA detection in saliva. Eu2O3 NCs and disposable syringe filter equipped with nitrocellulose membrane are employed as nanoprobes and bioassay platform, respectively. The whole assay can be carried out within 10 min, including incubation, labeling, and washing procedures, which allows both quantitatively time‐resolved (TR) and qualitatively visual detection of CEA.Advanced Science (2021).

NASA test of mega Moon rocket engines cut short

NASA said the ‘hot-fire’ test of the RS-25 engines that will power the Artemis lunar missions shut down prematurely NASA conducted a test firing of the engines for its giant Space Launch System (SLS) lunar rocket on Saturday but they shut down earlier than planned, the space agency said. The “hot-fire” test at the Stennis […]

Watch NASA test the world’s most powerful rocket ever on Saturday

NASA is going to light up the most powerful rocket it’s ever built Saturday (Jan. 16), though it won’t go anywhere. The test, scheduled for sometime between 5:00 p.m. and 7:00 p.m. EST, will be the first test of the core of the Space Launch System (SLS). That’s the rocket NASA hopes will one day […]
