Diagnostic Pill Samples Bacteria While Traveling Inside Gut

The microbiome inside our gut contains a wide variety of bacterial species, some of which are a source of disease. Currently, only the lower intestine can be sampled non-invasively to learn about the bacterial flora within, so there’s actually little knowledge about what goes on higher up the GI tract. Researchers at Tufts University have [&h (Read more...)

New Infrared Chemical Imaging Method to Diagnose Cancers

Prostate cancer can be very difficult to diagnose, with way too many patients undergoing surgeries that turn out to be unnecessary. Now, researchers at Purdue University, Boston University, and the Chinese Academy of Sciences have developed an infrared chemical imaging technique that may improve diagnostic studies and in the process cut down on exc (Read more...)

CompCyst Tool Developed to Identify Precancerous Cysts

Researchers from Johns Hopkins Kimmel Cancer Center have developed a new computational and biomolecular tool, dubbed CompCyst, that can identify precancerous pancreatic cysts. The technology provides a new method for reliably identifying cancer-causing cysts from those that are not cancer-causing. The teams work demonstrates that in over half of pa (Read more...)

New High-Res Holographic Microscope to Study Live Cells

Nanolive, a spinoff company of École polytechnique fédérale de Lausanne (EPFL) in Switzerland, has just introduced a holographic microscope that can image live cells at high resolution over extended time periods. Nanolive’s CX-A device relies on a low energy light beam to penetrate the sample, which does not interfere wit (Read more...)

Scientists Develop New Probe to Light Up Cancer

A team of researchers in Ireland has collaborated on developing a new fluorescent molecular probe that can hone in on and light up cancer in an exciting new way. The technology will hopefully have important consequences for cancer resection surgeries, allowing physicians to remove tumors while sparing healthy tissues. Previously developed fluoresce (Read more...)

Microfluidic Chip Allows Embryonic Stem Cells to Differentiate

Complex multicellular organisms, such as ourselves, start out from stem cells that differentiate into different kinds of cells. This process is controlled by groups of cells that secrete special signaling molecules called morphogens, which guide nearby stem cells to turn into the kinds of cells that should be located in that region. This is an [&he (Read more...)

Low Cost Medical Devices for Low-Resource Regions: Interview with Prof. Saad Bhamla, Georgia Tech

Advances in medical technology continue apace, with sophisticated new medical devices and therapies becoming available on an ongoing basis. However, medical technology often comes at a premium, and for low-resource regions sometimes even relatively basic medical devices, such as hearing aids, are inaccessible because they are too expensive. Similar (Read more...)

Ultra-Thin Probe Assesses Tissues Deep Within Lungs

Assessing the health of tissues deep inside the body is a major need and challenge in medicine. Imaging modalities such as MRI, CT, and ultrasound provide very little information about the composition and environment of tissues being examined. Now, researchers at the University of Edinburgh, Heriot-Watt University, and Bath University, all in the U (Read more...)

Liquid Biopsy for Monitoring Transplanted Stem Cells

Researchers from the University of Maryland, University of Pennsylvania, and Emory University have demonstrated that a blood test can be used to track the efficacy of transplanted stem cells. They analyzed tiny cellular components called exosomes that were secreted from transplanted stem cells. “Exosomes contain the signals of the cells they& (Read more...)

3D Printed ELISA Pipette Tips for Low Cost Medical Testing

Researchers at the University of Connecticut have developed a 3D printed enzyme-linked immunosorbent assay (ELISA) device, which fits onto a normal pipette and substantially reduces the time and cost of this common medical test. The device could allow for medical testing in remote or low-resource regions, where such tests would otherwise be unavail (Read more...)
