New optical fiber probe could help differentiate between healthy and cancerous tissue during surgery

An optical fiber probe can distinguish cancer tissue and normal tissue at the margins of a tumor being excised, in real time, by detecting the difference in pH between the two types of tissue.

Salk scientists discover key to amplification of ‘invader’ signals

When a receptor on the surface of a T cell -- a sentry of the human immune system -- senses a single particle from a harmful intruder, it immediately kicks the cell into action, launching a larger immune response. But exactly how the signal from a single receptor, among thousands on each T cell, can be amplified to affect a whole cell has puzzled immunologists for decades.

IED detection technique could be potential diagnostic tool for dementia

Researchers from the University of Adelaide in South Australia developed the Improvised Explosive Device (IED) detection method in 2014, which used light intensity to determine the presence of explosive residue.

Scientists develop new optical fiber-based probe for brain temperature measurements

The brain is the most temperature-sensitive organ in the body. Even small deviations in brain temperature are capable of producing profound effects--including behavioral changes, cell toxicity, and neuronal cell death. The problem faced by researchers and clinicians is how to measure and understand the

New optical detection technology could be effective to monitor blood-glucose levels

A newly developed method for detecting glucose based on how it absorbs a specific type of light could spell the end of the painful, invasive finger-prick tests diabetics rely on to monitor their condition, says a Texas A&M University biomedical engineer who is developing the technology.

Salk Institute researchers use super-resolution microscope to image vital receptors in lymph nodes

When the body is fighting an invading pathogen, white blood cells--including T cells--must respond. Now, Salk Institute researchers have imaged how vital receptors on the surface of T cells bundle together when activated.

Scientists develop new technology that helps visualize translation of mRNA into proteins

For the first time, scientists at Albert Einstein College of Medicine have developed a technology allowing them to "see" single molecules of messenger RNA as they are translated into proteins in living mammalian cells. Initial findings using this technology that may shed light on neurological diseases as well as cancer were published online today in Science.

New miniaturized microscope offers unprecedented insight into nervous system function

A microscope about the size of a penny is giving scientists a new window into the everyday activity of cells within the spinal cord. The innovative technology revealed that astrocytes--cells in the nervous system that do not conduct electrical signals and were traditionally viewed as merely supportive--unexpectedly react to intense sensation.

ATR-FTIR spectroscopy could be effective for detecting ulcerative colitis

A minimally invasive screening for ulcerative colitis, a debilitating gastrointestinal tract disorder, using emerging infrared technology could be a rapid and cost-effective method for detecting disease that eliminates the need for biopsies and intrusive testing of the human body, according to researchers at Georgia State University.

New blood test may potentially facilitate detection of Alzheimer's disease at early stage

Today, Alzheimer's disease is diagnosed too late. In collaboration with a research team at the university and German Center for Neurogenerative Diseases in Göttingen, Researchers at Ruhr-Universität Bochum have developed a blood test that may potentially facilitate detection of Alzheimer's at an early stage. It is based on an immuno-chemical analysis using an infrared sensor.
