Chip design can rapidly and efficiently test for multiple pathogens simultaneously, potentially reducing foodborne illness. Researchers have developed a new method for detecting foodborne pathogens that is faster, cheaper, and more effective than existing methods. Their microfluidic chip uses light to detect multiple types of pathogens simultaneously and is created using 3D printing, making it easy to fabricate in large amounts and modify to target specific pathogens. The researchers hope their technique can improve screening processes and keep contaminated food out of the hands of consumers.

Scientists at the University of Sydney have developed a gene-editing tool with greater accuracy and flexibility than the industry standard, CRISPR, which has revolutionized genetic engineering in medicine, agriculture and biotechnology.

SeekRNA uses a programmable ribonucleic acid (RNA) strand that can directly identify sites for insertion in genetic sequences, simplifying the editing process and reducing errors.

The new gene-editing tool is being developed by a team led by Dr. Sandro Ataide in the School of Life and Environmental Sciences. Their findings have been published in Nature Communications.

Our bone marrow—the fatty, jelly-like substance inside our bones—is an unseen powerhouse quietly producing 500 billion new blood cells every day. That process is driven by hematopoietic stem cells that generate all of the various types of blood cells in our bodies and regenerating themselves to keep the entire assembly line of blood production operating smoothly.

As with any complex system, hematopoietic stem cells lose functionality as they age—and, in the process, contribute to the risk of serious diseases, including blood cancers. We know that the risk of developing aging-associated diseases is different among different individuals...
