Metal deposition and shape reproduction at biological temperatures on samples at the cellular level – Scientific Reports

Non-thermal damage Al film coating on bovine spermatozoa Sperm in good condition were separated from frozen-preserved bovine sperm using a special microfluidic channel16. The adsorption of the separated sperm on the amino group-modified glass substrate was confirmed, and this adsorption was then compared with that of the sperm on a normal glass substrate using light …

New smartphone clip-on can detect Zika virus in blood samples

As seen with the covid-19 pandemic, detection methods that are rapid, simple, accurate and sensitive are critical to detect viral pathogens and to control the spread of infectious diseases. Unfortunately, laboratory-based methods often require trained personnel and involve complex procedures. In a new study, researchers at the University of Illinois Urbana-Champaign have combined their efforts …

"Disruptive" means a herbicide-linked herbicide found in 80% of U.S. urine samples

“Disruptive” means a herbicide-linked herbicide found in 80% of U.S. urine samples

More than 80 percent of the urine samples from children and adults in a US health study contained a herbicidal chemical linked to cancer, something that researchers have called “disturbing” and “worrying”. The report of a unit from the Centers for Disease Control and Prevention (CDC) found that of 2,310 urine samples taken from a …

NASA says its plan to return Mars samples to Earth is certain, but some people are worried

Credit: Pixabay / CC0 Public Domain Since September, the Perseverance rover has plucked along an ancient river delta on Mars, and its robotic arms extend with swirling steel drills to core rocks, scoop up soil and suck in small amounts of the red planet’s atmosphere into titanium tubes. The plan, under NASA’s Jet Propulsion Laboratory, …

What happened before, during and after the formation of the solar system? A recent study of the asteroid Ryugu contains the answers: A team of scientists conducts a comprehensive analysis of samples returned from Japan Aerospace Exploration Agency’s Hayabusa2 mission and provides invaluable insights into the formation and evolution of our solar system

Japan Aerospace Exploration Agency’s Hayabusa2 mission returned unpolluted primitive asteroid samples to Earth. A comprehensive analysis of 16 particles from the asteroid Ryugu revealed many insights into the processes that worked before, during and after the formation of the solar system, with some still forming the surface of the current asteroid. Elemental and isotopic data …
