In one of the biggest advances to come from the H. Lee Moffitt Cancer Center & Research Institute in its 16-year history, researchers have unlocked at least part of the mystery of how tumors flourish undetected by keeping their presence a secret from sentries of the bodys immune system.
"Flying beneath the radar" is how Nature Reviews Cancer (http://www.nature.com/cgi-taf/DynaPage.taf?file=/nrc/journal/v4/n1/full/nrc1261_fs.html) labels the mechanism of tumors evading capture, a process described by Hua Yu, Ph.D., and her colleagues at Moffitt and the University of South Florida College of Medicine. Their findings are published in the current issue of the journal Nature Medicine.
"Cancer is allowed to wreak havoc on the bodys immune system because it knows how to fool the bodys defensive arsenal," explains Jack Pledger, Ph.D., Associate Center Director for Basic Science and Professor of Biochemistry at USF. "The discoveries of Dr. Yu give us vital information about how tumors stay invisible. It opens the way for new treatments to help flush the cancer cells into the open, so the bodys armies against disease can destroy them."

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
