I won’t claim to be a science expert, but found this article very interesting about a DNA Reader just a little larger than a USB drive.
For years, Illumina Technology has the lead in genome sequencing. Their gear is good and from what I understand their gear is expensive. The MinION (from Oxford Nanopore ) is an inexpensive alternative with some great upsides.
The DNA sequencer is just over $1,000 at the time of this post. Traditionally, a DNA sequencer could only read about 200 basis. A “basis” is a nucleobasis which is a collection of biologicial compounds that make up the basic building blocks of nucleic acid… or DNA.
The MinION is impressive with the ability to read 900,000 basis. Also called “long reads.” With the long reads you get a better idea of the compounds making up the DNA. Although the longer reads are not as accurate as short reads, the trade-off isn’t bad. The amount of time and effort to construct a long read from a collection of short reads is considerable. The less accurate long reads from MinION and not that far off base, thus a bit of a break through.
It is simply amazing that 15 years ago the human genome was a global effort, yet today it can be done in a device no larger than a flash drive.
If you’ve ever misplaced a phone or USB drive in your house and wished for a way to find it, a dog with a keen nose and a playful attitude could have helped you out. Fortunately, with skills like that, our canine friends are finding a much higher calling working with police, the FBI, and homeland security.
As devices improve, a tiny microSD the size of a fingernail and less than a millimeter thick can hold hundreds of gigabytes of data. With this advancement comes the tools for criminals to hide and transfer enormous amounts of information without even lifting a finger. Where does that leave the fine men and women tasked with staying one step ahead? In Ogden, Utah and across the United States, they are getting the edge with their friendly Labrador companions. Ogden is home to one of fewer than two dozen “Electronic Sniffing” dogs in the nation’s police force and his name is URL (pronounced “Earl”). URL sniffs out electronic media like flash drives, memory cards, and cell phones. While they’re not exactly cryptography experts, they are consistently able to find devices that humans might otherwise miss.
Starting around 2015 with a K-9 named Bear, investigations involving trafficking, pornography, and counterterrorism have had success with the sharp noses of the dogs alongside them. The dog’s expertise comes from playful, but rigorous training exercises and are on a food-reward diet. Dogs could be led to search an office piled to the ceiling with boxes, or an open field with evidence buried underground, and within minutes they will lead their handlers to the prize. What’s the secret? The common element between all these eletric devices is a circuitboard. Compounds are added to the board to help them deal with overheating and it’s this compound that officers train their K-9 partners with. Initially using large amounts and then all the way down to a standard thumb drive, the dogs familiarize the scent and the training to be able to search houses, vents, cars, and people if deemed necessary.
From detecting drugs, to explosives, and now to electronics, the utility of a canine’s senses can’t be understated. Craig Angle the co-director of the Canine Performance Sciences program at Auburn University said he’s seen dogs identify very small targets from incredible distances. “I’ve seen them detect two ounces of explosives from more than 300 yards away,” he said. “They can detect through barriers and masking agents. We see a lot of natural instincts in a dog’s ability to detect innate behaviors like understanding and utilizing wind currents and scent plume.” From a researcher perspective and from the law enforcement officers working with these animals, it’s clear that the full potential of cooperation like this has immense potential for evidence gathering in the future.
Microsoft is creating a new connection for their tablet and laptop devices but as revealed in their newest patent filing, the working version of its Surface connector port will resemble the magnetic snap of past Apple devices while maintaining current USB-C compatibility standards.
