With a single breath, a Breathalyzer can tell a police officer when a driver has had too much to drink. Now, thanks to a team of investigators at the Israel Institute of Technology, a single breath may be enough to tell a doctor that their patient has cancer.
A normally benign protein found in the human body appears to be able - when paired with nanoparticles - to zero in on and kill certain cancer cells, without having to also load those particles with chemotherapy drugs.
One tool in the eventual armamentarium of clinical oncologists could be the new microfluidic image cytometry (MIC) platform developed by Hsian-Rong Tseng and his colleagues at the University of California, Los Angeles and the Nanosystems Biology Cancer Center.
Both certificate programs are designed to meet the growing demand for skilled professionals who can conceptualize, design and manufacture optical and optomechanical components, systems and instruments.
Researchers demonstrate enhanced performance of a hybrid photovoltaic device, where poly[3-hexylthiophene] (P3HT) is used as active material and a solution-processed thin flat film of ZnO modified by a self-assembled monolayer (SAM) of phenyl-C61-butyric acid (PCBA) is used as electron extracting electrode.
Science has a long history of crossing borders, bridging cultures and balancing the public good with private gain. That tradition, the focus of the upcoming Kavli Prize Science Forum, may face a more challenging future.
In experiments with potentially broad health care implications, a research team led by a University of Washington physicist has devised a method that works at a very small scale to sequence DNA quickly and relatively inexpensively.
Building on an enzyme found in nature, researchers at Rensselaer Polytechnic Institute have created a nanoscale coating for surgical equipment, hospital walls, and other surfaces which safely eradicates methicillin resistant Staphylococcus aureus (MRSA), the bacteria responsible for antibiotic resistant infections.
A research team from Rome, Grenoble and London report that the strength of the superconductivity - its ability to persist as temperature is increased - correlates in certain oxide materials with structures visible over a range of length scales. Intriguingly, these structures extend almost to the millimeter scale, and have a 'fractal' nature, similar to the intricate patterns in a snowflake.
In one of only two studies of its kind, a study from researchers at Tufts University School of Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts demonstrates that non-viral gene therapy can delay the onset of some forms of eye disease and preserve vision. The team developed nanoparticles to deliver therapeutic genes to the retina and found that treated mice temporarily retained more eyesight than controls.
Researchers at the Georgia Institute of Technology are using funding from the Advanced Research Projects Agency - Energy - also known as ARPA-E - to pursue two different, but related, approaches for removing carbon dioxide from the flue gases of coal-burning power plants.
