Old age is the greatest risk factor for many diseases, including Alzheimer's disease (AD) and cancer. Geroprotectors are a recently identified class of anti-aging compounds. New Salk research has now identified a unique subclass of these compounds, dubbed geroneuroprotectors (GNPs), which are AD drug candidates and slow the aging process in mice.
Around the world, 425 million people live with diabetes and upwards of 15 percent develop foot ulcers, which increases their risk of death 2.5 times. A new nitric oxide-releasing technology has the potential to cut down the healing time of diabetic foot ulcers from 120 days to 21 days.
Indiana University scientists paired drug-delivering nanoparticles like dance partners to reveal that molecules attach to targets on cells differently based upon their position in time. The discovery could improve methods for screening drugs for therapeutic effectiveness.
Scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), in collaboration with the Monash University Australia, have succeeded in significantly increasing the stability and biocompatibility of special light-transducing nanoparticles. They have developed so-called "upconverting" nanoparticles that not only convert infrared light into UV-visible light, but also are water-soluble, remain stable in complex body fluids, and can be used to store medications. They have created a tool that could potentially make the fight against cancer more effective.
Machine learning is increasing the pace of development of customised carbon surfaces with a wide variety of applications
A new IMAS-led study has found that Antarctic krill are resilient to the increasing acidification of the ocean as it absorbs more C02 from the atmosphere due to anthropogenic carbon emissions. Krill are one of the most abundant organisms on Earth and a critical part of the Southern Ocean marine ecosystem.
Purple phototrophic bacteria -- which can store energy from light -- when supplied with an electric current can recover near to 100 percent of carbon from any type of organic waste, while generating hydrogen gas for use as fuel. This novel finding is reported in open-access journal Frontiers in Energy Research.
A new method for learning the structures of small molecules, such as hormones, is 'like science fiction.'
Carnegie Mellon University researchers have developed a synthetic molecule that can recognize and bind to double-stranded DNA or RNA under normal physiological conditions. The molecule could provide a new platform for developing methods for the diagnosis and treatment of genetic conditions.
For years, green has been the most reliable hue for live brain imaging, but after using a new high-throughput screening method, researchers at the John B. Pierce Laboratory and the Yale School of Medicine, together with collaborators at Stanford University, have identified a new fluorescent protein that will make it possible for live neurons to glow red when activated.
