Move over, quantum dots – quantum rods could be the next big display technology. These tiny sticks could improve 3D displays for VR headsets, and now engineers at MIT have overcome a logistical hurdle by arranging them onto a scaffold made of DNA.Conti… Continue reading Quantum rods on DNA scaffolds could boost future VR displays
Certain gut bacteria have been linked to colon cancer, but now they might get a chance at redemption. Scientists have engineered “pickpocket” bacteria to detect colorectal cancer, with a 100% success rate in mouse tests.Continue ReadingCategory: Medica… Continue reading “Pickpocket” bacteria steal tumor DNA for accurate cancer diagnoses
A couple of weeks ago, we noted with interest that the space shuttle Endeavour (OV85) would be set up as a full-stack launch configuration display, complete with external fuel tank …read more Continue reading Hackaday Links: July 30, 2023
It may not be as catchy a name as Iron Man, but in a fight you might be better off betting on Glass DNA Nanolattice Man instead. Engineers at the University of Connecticut have developed a very strong and lightweight new material out of DNA that self-a… Continue reading Glass-coated DNA material boasts 4x strength of steel
Scientists have developed a new way to tap into the incredible data storage density of DNA in a more scalable way. A “biological camera” imprints images into the DNA of living cells, tagged with barcodes to retrieve data.Continue ReadingCategory: Scien… Continue reading “Biological camera” stores data in DNA of living bacteria
Over the last few years, we’ve all been given a valuable lesson in both the promise and limitations of advanced molecular biology methods for clinical diagnostics. Polymerase chain reaction (PCR) …read more Continue reading Open-Source LAMP Instrument Aimed at Clinicians and Biohackers Alike
Researchers have successfully mapped the dog epigenome, opening the door to an improved understanding of how environmental factors influence their genetic expression, as well as ours.Continue ReadingCategory: Biology, ScienceTags: Epigenetics, Genome, … Continue reading Researchers map dog epigenome for the first time
Researchers have developed a novel way of detecting brain cancer, using nanowires to ‘catch-and-release’ DNA in urine, enabling them to detect mutations that signify the presence of a brain tumor. Their method may one day mean that invasive tissue biop… Continue reading DNA ‘catch-and-release’ enables urine test for brain cancer
It’s no secret that red meat and fried foods aren’t great for your health, but Stanford scientists have discovered a new potential mechanism for why. The team found that cooking food at high heat damages its DNA, and that in turn could damage your own … Continue reading Meat’s damaged DNA damages your own to raise cancer risk, says study
The New York Times has a long article on the investigative techniques used to identify the person who stabbed and killed four University of Idaho students.
Pay attention to the techniques:
The case has shown the degree to which law enforcement investigators have come to rely on the digital footprints that ordinary Americans leave in nearly every facet of their lives. Online shopping, car sales, carrying a cellphone, drives along city streets and amateur genealogy all played roles in an investigation that was solved, in the end, as much through technology as traditional sleuthing…
