Scientists are using new imaging technology to help them perform "virtual biopsies," – biological profiles of specific tumors that may help predict a patients response to treatment and probability of long-term survival. This whole new realm of imaging is called functional MRI (magnetic resonance imaging), a process that offers insight into a tumors character, not just its superficial structure.
In these images of the breast, the lighter and brighter the color, the more aggressive the tumor and the greater the growth of angiogenesis, or the blood vessel growth around them. Functional MRI reveals small islands of the tumor that are resistant to chemotherapy
Using functional MRI, Dr. Michael Knopp, a radiologist and a member of The Ohio State University Comprehensive Cancer Centers Experimental Therapeutics Program, is studying breast, prostate, pancreatic tumors and others to see if some of their particular biological quirks are related to response to treatment and survival.
Knopp says while X-rays can reveal information about a tumors size and shape, that information alone is not enough to help physicians plan and tailor some of the newest treatments. "Its not what we see, but what we dont that may be more important."

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
