Published Tiny light-up barcodes identify molecules by their twinkling
(via sciencedaily.com) An imaging technique could make it possible to peer inside cells and watch dozens of different molecules at once -- by labeling them with short strands of light-up DNA that blink on and off with their own unique rhythm. Though they're all the same color, the technique makes it possible to distinguish as many as 56 types by their twinkling, more cheaply than traditional methods and without fading over time.
Published Pin-sized sensor could bring chemical ID to smartphone-sized devices
(via sciencedaily.com) Engineers have developed a spectrometer so small and simple that it could integrate with the camera of a typical cellphone without sacrificing accuracy.
Published CRISPR-chip enables digital detection of DNA without amplification
(via sciencedaily.com) Researchers have found multiple applications for the CRISPR gene editing technology since it came into use by the scientific community.
Published Machines whisper our secrets
(via sciencedaily.com) Scientists showed they could reconstruct what a researcher was doing by recording the sounds of the lab instrument used. The method accurately detects what type of DNA a DNA synthesizer is making. That means academic, industrial, and government labs are potentially wide open to espionage that could destabilize research, jeopardize product development, and even put national security at risk.
Published New weapon to combat counterfeit goods: use your smartphone to check for fake merchandise
(via sciencedaily.com) Researchers have invented a chemical fingerprint that, when used with a phone app, reveals whether a product is genuine or a fake; the fingerprints have been tested and earned a 100 percent success rate.
Published Researchers unveil Internet of Things security feature
(via sciencedaily.com) Original source Integrated circuit designers have developed a new approach for creating secure keys and IDs on Internet of Things (IoT).
Published Sensitive sensor detects Down syndrome DNA with blood test during pregnancy
(via sciencedaily.com) Original source According to the Centers for Disease Control and Prevention, Down syndrome is the most common birth defect, occurring once in every 700 births. However, traditional noninvasive prenatal tests for the condition are unreliable or carry risks for the mother and fetus. Now, researchers have developed a sensitive new biosensor that could someday be used to detect fetal Down syndrome DNA in pregnant women's blood.
