Visible Resonance Raman Spectroscopy Could Advance Tumor Identification
NEW YORK, Oct. 30, 2019 — A team of researchers from the U.S. and China, led by Robert Alfano from City University of New York, has used visible resonance Raman (VRR) spectroscopy to identify and grade gliomas, a common tumor of the central nervous system. The researchers...
Researchers Generate New Form of Light
BERLIN, Oct. 30, 2019 — A team composed of researchers from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Israel Institute of Technology (Technion), and Technische Universitaet Berlin (TU Berlin) has generated and characterized a new...
New Molecule Marker Enables ‘Unprecedented’ Study of Mitochondria
NAGOYA, Japan, Oct. 23, 2019 — A team at Nagoya University’s Institute of Transformative Bio-Molecules has developed a marker molecule that bypasses the problem of photobleaching in STED microscopy. It’s allowing an unprecedented view of live mitochondria, which could help...
The Eyes Behind Surgical Robots
Oct 22, 2019 — The first robotic surgery took place in 1985 when the PUMA 560 was used in a stereotaxic operation in which computed tomography (or x-ray) was used intraoperatively to guide a robot as it inserted a needle into the brain for biopsy. In the late...
New Technique Enhances Superresolution Microscopy
BIELEFELD, Germany, Oct. 22, 2019 — Researchers at Bielefeld University have demonstrated improvements in superresolution structured illumination microscopy (SR-SIM), demonstrating that the technique is possible in real time and at a very high imaging rate, which is enhancing...
Laser Technology Cuts Critical Blood Incubation Time
MELBOURNE, Australia, Oct. 21, 2019 — A new laser technology vastly improves pretransfusion testing, cutting blood incubation time from the current standard of five minutes to just 40 seconds. Developed by researchers at the Bioresource Processing Institute of Australia (BioPRIA),...
New Light-Activated Metal Compound Kills Cancer Energy Source
COVENTRY, England, Oct. 18, 2019 — A team led by University of Warwick researchers is using light to activate a cancer-killing compound that attacks a vital energy source in cancer cells. This technique could be used not only to treat cancer, but also to help reduce side effects of...
Practice Makes Perfect: 3D Model Aids Surgical Outcomes
LOS ANGELES, Oct. 17, 2019 — Using a 3D virtual reality model to prepare for kidney tumor surgery could substantially improve the outcome of the procedure. A team led by UCLA found specifically that such preparation can result in reduced operating times, less blood loss during...
Mapping Unexplored Genome Region Could Boost Genetic Testing
AURORA, Colo., Oct. 17, 2019 — Using advanced imaging techniques, researchers have mapped a region of the human genome that was once uncharted. This could prompt new genetic testing, as that region gives rise to a variety of diseases. The team, led by researchers from the...
New BPV System Flaunts More Power, Longer Life
BEIJING, Oct. 14, 2019 — A new biophotovoltaics (BPV) system developed by researchers at the Chinese Academy of Sciences’ Institute of Microbiology has proven more powerful than any similar system. It also touts the greatest longevity. The new system is based on a...
Photoacoustic Technology Could Revolutionize Cancer Surgery
WATERLOO, Ontario, Oct. 8, 2019 — Researchers at the University of Waterloo in Ontario, Canada, have developed photoacoustic technology that can precisely locate and distinguish all of a cancerous tumor during surgery. This could help ensure that healthy tissue remains intact while...
Nanolaser Proves Fully Functional Within Living Tissue
EVANSTON, Ill., Oct. 8, 2019 — Researchers at Northwestern University have created a nanolaser that can be used in living tissues without harming them. Developed in conjunction with a team from Columbia University, the nanolaser can be 50 nm to 150 nm thick, which allows it to...
Danforth Center Expands to Include New Lab, Technologies
