Stanford, CA (Scicasts) – If engineers at Stanford have their way, biological research may soon be transformed by a new class of light-emitting probes small enough to be injected into individual cells without harm to the host.
Barcelona, Spain (Scicasts) – Researchers from the Institute of Photonic Sciences (ICFO), in collaboration with the CSIC and Macquarie University in Australia, have developed a new technique, similar to the MRI but with a much higher resolution and sensitivity, which has the ability to scan individual cells.
Princeton, NJ (Scicasts) – Tiny and swift, viruses are hard to capture on video. Now researchers at Princeton University have achieved an unprecedented look at a virus-like particle as it tries to break into and infect a cell. [Video]
Oxford, UK (Scicasts) – Tiny self-assembling transport networks, powered by nano-scale motors and controlled by DNA, have been developed by scientists at Oxford University and Warwick University.
Los Angeles, CA (Scicasts) – A lightweight and field-portable device invented at UCLA that conducts kidney tests and transmits data through a smartphone attachment may significantly reduce the need for frequent office visits by people with diabetes and others with chronic kidney ailments.
Tempe, AZ (Scicasts) – A chemical component present in the nightshade family of plants is one of the world's most tenaciously addictive substances. It is the nicotine contained in tobacco and found in high concentrations in cigarettes. Smoking remains a global scourge; in the U.S. it is the leading source of preventable death.
Cambridge, MA (Scicasts) – Nanoparticles that deliver short strands of RNA offer a way to treat cancer and other diseases by shutting off malfunctioning genes. Although this approach has shown some promise, scientists are still not sure exactly what happens to the nanoparticles once they get inside their target cells.
West Lafayette, IN (Scicasts) – Researchers have found a way to see synthetic nanostructures and molecules using a new type of super-resolution optical microscopy that does not require fluorescent dyes, representing a practical tool for biomedical and nanotechnology research.
Cambridge, UK (Scicasts) – A sensing system developed at Cambridge is being commercialized in the UK for use in rapid, low-cost DNA sequencing, which would make the prediction and diagnosis of disease more efficient, and individualized treatment more affordable.
Rehovot, Israel (Scicasts) – For years, scientists around the world have dreamed of building a complete, functional, artificial cell. Though this vision is still a distant blur on the horizon, many are making progress on various fronts.
