Sunscreens, lotions, and cosmetics contain tiny metal nanoparticles that wash down the drain at the end of the day, or are discharged after manufacturing. Those nanoparticles eventually end up in agricultural soil, which is a cause for concern, according to a group of environmental scientists that recently carried out the first major study of soybeans grown in soil contaminated by two manufactured nanomaterials.
Researchers have created a new type of biosensor that can detect minute concentrations of glucose in saliva, tears and urine and might be manufactured at low cost because it does not require many processing steps to produce.
Scientists have broken the limit of light resolution at the nanoscale and delivered a fundamental insight into how light and matter interact, which could lead to the development of enhanced bio-sensors for healthcare and more efficient solar cells and displays.
Computing prime factors may sound like an elementary math problem, but try it with a large number, say one that contains more than 600 digits, and the task becomes enormously challenging and impossibly time-consuming. Now, a group of researchers at UC Santa Barbara has designed and fabricated a quantum processor capable of factoring a composite number - in this case the number 15 - into its constituent prime factors, 3 and 5.
A major improvement in the world's lightest solid material and best solid insulating material may put more of this space-age wonder into insulated clothing, refrigerators with thinner walls that hold more food, building insulation and other products.
Measuring proteins in real-time down to fM solution concentration levels, corresponding to only a few thousand of protein molecules, has been demonstrated for the first time using a hybrid photonic-plasmonic Whispering Gallery Mode biosensor. Its unprecedented sensitivity is due to optical trapping of proteins at highly sensitive plasmonic hotspots.
A technologist at NASA's Goddard Space Flight Center is experimenting with atomic layer deposition techniques that might provide an effective technique for defending sensitive spacecraft components from high-velocity bombardments in space.
Researchers have developed a novel system to simultaneously deliver a sustained dose of both an immune-system booster and a chemical to counter the cancer's secretions, resulting in a powerful therapy that, in mice, delayed tumor growth, sent tumors into remission, and dramatically increased survival rates.
Using a compound in tea that is attracted to prostate tumor cells, researchers at the University of Missouri have developed a radioactive gold nanoparticle that kills prostate tumors, without triggering common side effects of prostate cancer therapy.
