Screen-printing method can make wearable electronics less expensive

The glittering, serpentine structures that power wearable electronics can be created with the same technology used to print rock concert t-shirts, new research shows. The study, led by Washington State University researchers, demonstrates that electrodes can be made using just screen printing, creating a stretchable, durable circuit pattern that can…

New study findings add to the debate over long Covid symptoms | CNN

CNN  —  The majority of long Covid symptoms resolve within the first year after infection for people with mild cases of Covid-19, according to a large study conducted in Israel. “Mild disease does not lead to serious or chronic long term morbidity in the vast majority of patients,” said study…

Computer models determine drug candidate’s ability to bind to proteins

Combing computational physics with experimental data, University of Arkansas researchers have developed computer models for determining a drug candidate’s ability to target and bind to proteins within cells. If accurate, such an estimator could computationally demonstrate binding affinity and thus prevent experimental researchers from needing to investigate millions of chemical…

Symptoms of illness help pathogens spread amongst songbirds

It’s “Treasure Island” author Robert Louis Stevenson who is credited with coining the phrase, “You cannot make an omelet without breaking eggs.” For us humans, it’s now cliché. For pathogens, it’s words to live by. Or, rather, spread by. Like all living organisms, pathogens want to thrive. Aside from cellular…

Old and new stars paint very different pictures of the Triangulum Galaxy

Astronomers have been gazing at the Triangulum galaxy for centuries. But they’ve never seen it quite like this. On Jan. 11 at the 241st meeting of the American Astronomical Society in Seattle, a team led by scientists at the University of Washington and the Center for Computational Astrophysics will unveil…

NASA’s Webb uncovers star formation in cluster’s dusty ribbons

NGC 346, one of the most dynamic star-forming regions in nearby galaxies, is full of mystery. Now, it is less mysterious with new findings from NASA’s James Webb Space Telescope. NCG 346 is located in the Small Magellanic Cloud (SMC), a dwarf galaxy close to our Milky Way. The SMC…

New Webb image reveals dusty disk like never seen before

NASA’s James Webb Space Telescope has imaged the inner workings of a dusty disk surrounding a nearby red dwarf star. These observations represent the first time the previously known disk has been imaged at these infrared wavelengths of light. They also provide clues to the composition of the disk. The…

Controlled, localized delivery of blood thinner may improve blood clot treatment

Heparin has long been used as a blood thinner, or anticoagulant, for patients with blood clotting disorders or after surgery to prevent complications. But the medication remains difficult to dose correctly, potentially leading to overdosing or underdosing. A team of Penn State researchers combined heparin with a protein fragment, peptide,…
