Van Andel Institute scientists and collaborators have developed a new method for identifying and classifying pancreatic cancer cell subtypes based on sugars found on the outside of cancer cells. These sugars, called glycans, help cells recognize and communicate with each other. They also act as a cellular “signature,” with each subtype of pancreatic cancer cell possessing a different composition of glycans.

Comprehensive reference genomes have now been assembled for six ape species: siamang (a Southeast Asian gibbon), Sumatran orangutan, Bornean orangutan, gorilla, bonobo and chimpanzee. Areas of their genomes previously inaccessible because of structural complexity have now mostly been resolved.  The resource is already lending itself to comparative studies that offer new insights into human and ape evolution, and into what underlies the functional differences among these species.  

Northwestern University researchers have developed the first wearable device for measuring gases emitted from and absorbed by the skin. By analyzing these gases, the device offers an entirely new way to assess skin health, including monitoring wounds, detecting skin infections, tracking hydration levels, quantifying exposure to harmful environmental chemicals and more. 

Researchers have long explored how fragile microscopic containers naturally found in raw cow’s milk — called exosomes — can be used to carry medicine through the body. Now, Virginia Tech scientists have improved a freeze-drying process that keeps exosomes stable for up to a year at room temperature. It’s a game-changer, it may allow medicine to be encapsulated and shipped without a costly cold-supply chain.
