Over the years, archeologists have unearthed the remains of members of the infamous Franklin expedition, although it hasn't been possible to confirm the individuals' identities. Thanks to DNA analysis, however, scientists have now done so for the first time.Continue ReadingCategory: ScienceTags: University of Waterloo, DNA, History, Forensics
In a shining example of the inexorable march of technology, IBM has unveiled new semiconductor chips with the smallest transistors ever made. The new 2-nanometer (nm) tech allows the company to cram a staggering 50 billion transistors onto a chip the size of a fingernail.Continue ReadingCategory: Computers, TechnologyTags: IBM, Processor, Chips, Chip, Nanometers, Transistor, Moore's Law, Com
CRISPR-Cas9 is a revolutionary gene-editing tool, but it’s not without its downsides. Now, scientists at Harvard have demonstrated an alternative genetic engineering system called Retron Library Recombineering (RLR), which works without cutting DNA and can be quickly applied to huge populations of cells.Continue ReadingCategory: Biology, ScienceTags: gene therapy, Genetic engineering, Genetics, B
A team of researchers led by professor of pharmaceutical sciences John Chaputa at the University of California, Irvine (UCI) is developing methods for storing vast amounts of data on strands of synthetic DNA that are much tougher than natural DNA. The technique has already been used to encode the US Declaration of Independence on a single molecule.Continue ReadingCategory: ScienceTags: University
A new study published in the journal Nature is describing the extraction and sequencing of the oldest known sample of DNA. The sample comes from an ancient species of mammoth found in the Siberian permafrost and dates back nearly 1.2 million years.Continue ReadingCategory: ScienceTags: DNA, Paleontology, History, Evolution, Wooly mammoth, Dinosaurs, World's Oldest, New Atlas Audio
When a company the size of Amazon starts casually dropping the idea that it'd like to build a second headquarters, state-level politicians start to drool, with jobs and growth spinning around in their eye sockets even faster than dollar signs are spinning around in the eye sockets of Amazon execs. This, remember, is a company that occupies nearly 20 percent of all available office space in Seattl
Like weeds that grow back if you don’t remove the roots, cancer can keep returning thanks to lurking stem cells. Now, researchers have developed a “designer” DNA segment that can eradicate these cancer stem cells, with tests in mice showing promising early results in preventing the return of cancer.Continue ReadingCategory: Medical, ScienceTags: Cancer, Blood, Plasma, UCSD, UC San Diego, DNA
A new piece of open source software can radically speed up the process of DNA sequencing, according to researchers at Johns Hopkins University. Using a portable sequencer, the UNCALLED software can reduce a 15-day operation down to three days, or even one.Continue ReadingCategory: Medical, ScienceTags: DNA, Genome, Johns Hopkins University, New Atlas Audio
Scientists have successfully extracted DNA from insects trapped in amber. But before you start dreaming of a certain park, there’s one huge caveat to mention – any creatures you might revive from this would hail from the not-so-distant past of about 2014. Rather than resurrecting the dinosaurs, the study is more about working backwards to figure out the limits of DNA preservation.Continue Reading
No matter how useful a given drug may be, it’s a problem if it has adverse effects on healthy cells. Now researchers have demonstrated a new way to keep drugs on target, by wrapping them in a transport that can only be unlocked by a certain RNA sequence unique to cancer.Continue ReadingCategory: Medical, ScienceTags: Cancer, Drug, Drugs, Drug delivery, Technical University Munich, KTH Royal Insti is a social bookmarking place where you can share, find & discuss the best news around on most topics.
