Researchers have used a next-generation technology called long-read sequencing to diagnose a patient's rare genetic condition that current technology failed to diagnose.

A University of Arkansas for Medical Sciences (UAMS) research team led by Vladimir Zharov, Ph.D., D.Sc., has demonstrated the ability to kill single cancer cells using the world's smallest laser.

With the new FISH-Flow protocol, researchers are able to evaluate multitudes of cells at once for telltale mRNA species and proteins. The blended procedure provides a chance to see how multiple kinds of immune cells are responding to a foreign substance, making it possible to detect the presence of disease faster and earlier.

Cancer patients receiving chemotherapy- or immunotherapy-based treatments must undergo regular CT and PET scans—and in some cases, new biopsies—to evaluate the efficacy of the treatment. Flow cytometry, a method for identifying circulating tumor cells (CTCs) via a simple blood test, is much less invasive than scans and biopsies, and could be a game-changer in cancer treatment.

Turns out the Apple Watch is good for more than just telling the time, tracking steps, and dictating text messages. It can detect heart disease, too.

It's designed for large-scale medical studies.

The new tests show promise for detecting the neurodegenerative condition earlier

Far to the right side of the decimal point—beyond milli, micro, nano, pico, and femto—lives the atto, the metric prefix representing 10-18. Slap it in front of a unit of concentration, such as molar, and it means that something exists in an extraordinarily small amount—think one part per quintillion. That’s the realm of SHERLOCK, a new diagnostic system that can detect attomolar levels of viruses in a sample and also distinguish Zika from its close relative, dengue. This exquisitely sensitiv...

Engineered gut bacteria are capable of sensing colitis, an inflammation of the colon, in mice, say researchers.

By comparing behavioral observations with data from poop analysis, the researchers were able to uncover a smart strategy: mandrills don't ostracize members of the horde who've come down with a bug, but they do groom them less.
