New Method for Non-Invasive Prostate Cancer Screening

APL-Li-SERScancerdetection.jpg

A team of researchers led by Shaoxin Li at Guangdong Medical College in China has demonstrated the potential of a new, non-invasive method to screen for prostate cancer, a common type of cancer in men worldwide. They describe their laboratory success testing an existing spectroscopy technique called surface-enhanced Raman scattering (SERS) with a new, sophisticated analysis technique called support vector machine (SVM).

Doing More with Less: New Technique Uses Fraction of Measurements to Efficiently Find Quantum Wave Functions

Just two years ago, with the advent of a technique called direct measurement, scientists discovered they could reliably determine a system’s wave function by “weakly” measuring one of its variables (e.g. position) and “strongly” measuring a complementary variable (momentum). Researchers at the University of Rochester have now taken this method one step forward by combining direct measurement with an efficient computational technique.

Experiments Explain Why Some Liquids Are ‘Fragile’ and Others Are ‘Strong’

800px-Glass_is_Liquide.jpg

Only recently has it become possible to accurately “see” the structure of a liquid. Using X-rays and a high-tech apparatus that holds liquids without a container, a physicist at Washington University in St. Louis has compared the behavior of glass-forming liquids as they approach the glass transition. The results are the strongest demonstration yet that bulk properties like viscosity are linked to microscopic ones like structure.​

Duality Principle Is “Safe and Sound”: Researchers Clear Up Apparent Violation of Quantum Mechanics’ Wave-Particle Duality

Decades of experiments have verified the quirky laws of quantum theory again and again. So when scientists in Germany announced in 2012 an apparent violation of a fundamental law of quantum mechanics, a physicist at the University of Rochester was determined to find an explanation.

Organic Photovoltaic Cells of the Future

APL-Moritomo-OPV.jpg

Organic photovoltaic cells -- a type of solar cell that uses polymeric materials to capture sunlight -- show tremendous promise as energy conversion devices, thanks to key attributes such as flexibility and low-cost production, but have complex power conversion processes. To maneuver around this problem, researchers have developed a method to determine the absolute value of the charge formation efficiency. The secret of their method is the combination of two types of spectroscopy.
