Researchers developed a light yet strong material by combining two unexpected ingredients—DNA and glass. Working at the nanoscale provides scientists with a deep understanding and precision in crafting and analyzing materials. In broader-scale production, and even in natural settings, numerous materials are susceptible to defects and contaminants that can compromise their intricate architecture. Such vulnerabilities can [...]

Researchers at Houston's Rice University are developing an implant that could diminish deaths caused by cancer by half. The device will contain synthetically nurtured human cells and be embedded with sensors to keep track of cancer cells as they mutate, Knewz.com has learned. The implant will be no longer than 3 inches long. By: Rice University© Knewz (CA) In Texas alone, [...]

Most drugs are small molecules that bind firmly to a specific target—some molecule in human cells that is involved in a disease—in order to work. For example, a cancer drug's target might be a molecule that is abundant inside of cancer cells. The drug should hypothetically travel freely throughout the cell until it comes [...]

Scientists utilize nanotechnology to address a prevalent cause of vision loss. Scientists have discovered a way to use nanotechnology to create a 3D ‘scaffold’ to grow cells from the retina. This breakthrough could lead to innovative approaches for treating a common source of blindness. Researchers, led by Professor Barbara Pierscionek from Anglia Ruskin University (ARU), [...]

NIH study reviews 25 years of data and finds AI/ML can detect common hormone disorder. Artificial intelligence (AI) and machine learning (ML) can effectively detect and diagnose Polycystic Ovary Syndrome (PCOS), which is the most common hormone disorder among women, typically between ages 15 and 45, according to a new study by the National Institutes of Health (NIH). [...]

New insights are enhancing scientists’ efforts to stay ahead of COVID-19 and the next pandemic. Unexpected new insights into the ways COVID-19 infects cells could shed light on the virus’s adept ability to jump from one species to another and assist scientists in more accurately predicting its evolution. The pandemic has been marked by extensive debate regarding the mechanism [...]

Scientists can now show key differences in the blood of those who recover from Covid — and those who don't. More than three years into the pandemic, the millions of people who have suffered from long Covid finally have scientific proof that their condition is real. Scientists have found clear differences in the blood [...]

Researchers want to know why cells produce tiny packages called vesicles — and whether these bundles could be used for therapy. Graça Raposo was a young postdoc in the Netherlands in 1996 when she discovered that cells in her laboratory were sending secret messages to each other. She was exploring how immune cells react [...]

Magnetic bacteria possess extraordinary capabilities due to the magnetic nanoparticles, the magnetosomes, which are concatenated inside their cells. A research team at the University of Bayreuth has now transferred all of the approximately 30 genes responsible for the production of these particles to non-magnetic bacteria in a broad series of experiments. This resulted in [...]

Researchers have invented a nano-thin superbug-slaying material that could one day be integrated into wound dressings and implants to prevent or heal bacterial infections. The innovation – which has undergone advanced pre-clinical trials – is effective against a broad range of drug-resistant bacterial cells, including ‘golden staph’, which are commonly referred to as superbugs. The [...]
