Researchers at the University of California, San Diego School of Medicine have created a new generation of fast-acting fluorescent dyes that optically highlight electrical activity in neuronal...
View ArticleGoing live: Immune cell activation in multiple sclerosis
Biological processes are generally based on events at the molecular and cellular level. To understand what happens in the course of infections, diseases or normal bodily functions, scientists would...
View ArticleSugar solution makes tissues see-through
Japanese researchers have developed a new sugar and water-based solution that turns tissues transparent in just three days, without disrupting the shape and chemical nature of the samples. Combined...
View ArticleResearchers invent portable device for common kidney tests
(Medical Xpress)—A lightweight and field-portable device invented at UCLA that conducts kidney tests and transmits data through a smartphone attachment may significantly reduce the need for frequent...
View ArticleReal-time readout of neurochemical activity
Scientists have created cells with fluorescent dyes that change color in response to specific neurochemicals. By implanting these cells into living mammalian brains, they have shown how neurochemical...
View ArticleNarrow subset of cells is responsible for metastasis in multiple myeloma,...
Although it is among the most highly metastatic of all cancers, multiple myeloma is driven to spread by only a subset of the myeloma cells within a patient's body, researchers at Dana-Farber Cancer...
View ArticleFluorescent dyes 'light up' brain cancer cells
Two new fluorescent dyes attracted to cancer cells may help neurosurgeons more accurately localize and completely resect brain tumors, suggests a study in the February issue of Neurosurgery, official...
View ArticleA fluorescent molecule selectively labels live neurons in the brain for the...
Information processing and transmission in the brain hinge on electrical and chemical signals emitted and received by neurons. Now, A*STAR researchers have developed the first small molecule capable of...
View ArticleMetabolic activity and health of the skin microbiome
The skin microbiome is considered our first line of defense against pathogens. Across our bodies, we are covered with a diverse assemblage of bacteria. However, the skin can be a harsh environment for...

(Medical Xpress) -- A fluorescent dye that can be sprayed onto the oesophagus the food pipe could be used to detect oesophageal cancer earlier and spare patients unnecessary treatment, according to...
View ArticleSpecial camera detects tumors
Tumor removal surgeries pose a great challenge even to skillful and experienced surgeons. For one thing, tumor margins are blending into healthy tissue and are difficult to differentiate. For another,...
View Article'Spotlight' drug detects lingering cancer cells
(Medical Xpress)—When a tumor is surgically removed, there's always a chance the cancer will return. Even the tiniest bit of malignancy left behind creates a pathway for the disease to recur—often...
