A new wound dressing, however, is claimed to continuously kill...

The new substance, chemically synthesized and produced by bacteria, helps protect cells from radiation more effectively than...
The COVID-19 pandemic forced many countries to implement many restrictions to ensure people’s safety from the viral infection. Different face masks are being developed, each claiming that they are efficient enough to prevent the transmission of the viral disease.

An experimental gel is the first to match the strength and durability of knee cartilage, researchers say. The material may look like a distant cousin of Jell-O—which it is—but it’s incredibly strong. It’s 60% water, but a single quarter-sized disc can bear the weight of a 100-pound kettlebell without tearing or losing its shape. THE...
Multi-disciplinary research has led to the innovative fabrication of molecule-sized robots. Scientists are now advancing their efforts to make these robots interact and work together in the millions, explains a review in the journal Science and Technology of Advanced Materials. A molecular robot, which is typically between 100 nanometers to 100 micrometers long, requires an...
by Memorial Sloan Kettering Cancer Center Because of how aggressively they divide, cancer cells have an increased demand for building materials and energy. They meet these added demands by altering their metabolism—taking in larger amounts of fuel, for example. Historically, these metabolic changes have been considered a consequence rather than a cause of cancer, and...
Biological tissues have evolved over millennia to be perfectly optimized for their specific functions. Take cartilage as an example. It’s a compliant, elastic tissue that’s soft enough to cushion joints, but strong enough to resist compression and withstand the substantial load bearing of our bodies, key for running, jumping, and our daily wear and tear....
Researchers at the Terasaki Institute enhance tool for extraction of samples used in monitoring patient health (LOS ANGELES) – The interstitial fluid is a major component of the liquid environment in the body and fills the spaces between the body’s cells. In contrast, blood circulates only within the circulatory vessels of the body and is...
As scientists across the globe race to develop a vaccine against SARS-CoV-2, the coronavirus that causes COVID-19, an international team led by Davide Corti at Vir Biotechnology and David Veesler at the University of Washington has been working around the clock on a complementary approach – identifying neutralizing antibodies that could be used as a...
