Researchers exploit plasmonic nanoparticles to kill tumour cells

If you put your hand over a switched-on torch in the dark, it appears to glow red. This is because long-wavelength red light beams penetrate human tissue more effectively than short-wavelength blue light.

Researchers develop one-step analysis for detecting tumor markers in blood

Benign growth, or cancer? Tumor markers in the blood help determine whether the patient is afflicted with a malign tumor and whether it is excreting markers more vigorously - involving highly specific proteins. An increased concentration in the blood provides one indication of the disease for physicians. However, it has been quite expensive in time and effort to detect the markers thus far. This is because all kinds of molecules and proteins are teeming in the blood. To be able to detect a single specific one, doctors must first separate and purify the blood in several steps, and then isolate the marker they are searching for from the rest of the molecules.

MRI magnetic fields may diagnose, treat balance disorders and dizziness, say researchers

Expanding on earlier research, Johns Hopkins researchers report that people with balance disorders or dizziness traceable to an inner-ear disturbance show distinctive abnormal eye movements when the affected ear is exposed to the strong pull of an MRI’s magnetic field.

Local hyperthermia treatment induces mechanism of anti-tumor immune resistance

A combination of iron-oxide nanoparticles and an alternating magnetic field, which together generate heat, have activated an immune system response to tumors in mice according to an accepted manuscript by Dartmouth-Hitchcock Norris Cotton Center researchers in the journal Nanomedicine: Nanotechnology, Biology and Medicine released online on February 24, 2014.

Johns Hopkins researchers use tiny particles to train immune systems of mice to fight melanoma

Using tiny particles designed to target cancer-fighting immune cells, Johns Hopkins researchers have trained the immune systems of mice to fight melanoma, a deadly skin cancer. The experiments, described tk on the website of ACS Nano, represent a significant step toward using nanoparticles and magnetism to treat a variety of conditions, the researchers say.

Scientists present evidence of correlation between migration patterns of salmon and magnetic field

A team of scientists last year presented evidence of a correlation between the migration patterns of ocean salmon and the Earth's magnetic field, suggesting it may help explain how the fish can navigate across thousands of miles of water to find their river of origin.

New system incorporates transmit and search functions of avalanche transceiver into smartphone

Any enthusiast of winter sports dreads being overtaken by an avalanche, knowing that there is little chance of freeing oneself once buried beneath the mass of snow - snow that becomes hard as concrete until the buried person can no longer move as much as a finger.

Nature-engineered nanomotors could be used in targeted drug delivery

In the quest to shrink motors so they can maneuver in tiny spaces like inside and between human cells, scientists have taken inspiration from millions of years of plant evolution and incorporated, for the first time, corkscrew structures from plants into a new kind of helical "microswimmer."

MRI provides noninvasive way to measure iron levels in the brains of ADHD people

Magnetic resonance imaging provides a noninvasive way to measure iron levels in the brains of people with attention deficit hyperactivity disorder, according to a study being presented today at the annual meeting of the Radiological Society of North America. Researchers said the method could help physicians and parents make better informed decisions about medication.
