Scientists have developed a nano-thin superbug-slaying material that holds promise for future integration into wound dressings and implants to thwart or treat bacterial infections. The innovation – which has undergone advanced pre-clinical trials – is effective against a broad range of drug-resis
Researchers have developed a black phosphorus-based nanotechnology that can kill over 99% of drug-resistant bacteria. This innovative material, which degrades on contact with oxygen-producing bacteria-killing reactive oxygen species, can be integrated into wound dressings, implants, and medical instruments to treat and prevent bacterial infections.Kali Uchis Signed Red Moon in Venus Unboxing
Antibiotic resistance is a major global health threat, causing about 700,000 deaths annually, a figure which could rise to 10 million deaths a year by 2050 without the development of new antibacterial therapies.

“As the nanomaterial breaks down, its surface reacts with the atmosphere to produce what are called reactive oxygenThe new study tested the effectiveness of nano-thin flakes of black phosphorus against five common bacteria strains, including E. coli and drug-resistant golden staph. “If we can make our invention a commercial reality in the clinical setting, these superbugs globally wouldn’t know what hit them.”Lead researcher from UniSA, Dr Zlatko Kopecki, and his team performed the pre-clinical trials to show how daily topical application of the black phosphorus nanoflakes significantly reduced infection.
“We urgently need to develop new alternative non-antibiotic approaches to treat and manage wound infection,” he said.

You say tomato, these scientists say evolutionary mysteryBiologists have found evidence for evolutionary 'syndromes'-- sets of traits that occur together -- that help to explain how tomatoes first evolved their distinctive blend of color, sweetness, acidity and aroma. The research not only shines a light on how fruits evolve in the wild, but will also be valuable to crop-improvement efforts aimed at breeding more nutritious and appealing varieties of fruits.
