Remember when having an 8GB flash drive was quite the monumental thing? Flash memory has certainly come a long way and this has helped a lot with reducing cost too, as is the case with this 64GB flash drive from Transcend. It’s on sale for half price.

The Transcend 64GB JetFlash 500 retractable USB flash drive is no larger than the standard “slider” style USB drives that you’ve seen before, but this one happens to boast that incredible 64GB of memory. That’s the same size as some solid state drives you find in many Ultrabooks these days! Performance is right on par with what you’d expect, giving you read and write speeds of up to 19MB/s and 7MB/s, respectively.

The 64GB version of the Transcend JetFlash 500 is on sale for $37.99, compared to its regular retail price of $72.25. You can choose between the standard retail packaging or Amazon’s “Frustration-Free” packaging and the drive comes with that free Super Saver Shipping too.

If you don’t need 64GB, the other capacities are also on sale for about half price or better as well. Of course, the 64GB is the best deal though.

USB flash drives are getting more and more affordable. Case in point is the Patriot Xport XT Rage USB 2.0 high speed flash drive, the 32GB version of which is now on sale for an amazing $32. Remember that the regular price on this drive is $95, so you’re getting quite the deal.

One other cool feature about this drive is that there is no cap for you to lose. Instead, it uses a retractable design where you slide the top cover in to reveal the USB connector and then slide it back to cover it up. While it’s not really a “ruggedized” USB drive, the Xporter XT Rage is rubber coated for some level of protection from daily abuse too.

Yes, it’s not USB 3.0, but the quad channel technology allows the USB 2.0 drive to reach up to 27MB/s read and 25MB/s write. You can find it on sale on Amazon.com for the aforementioned $32. Variations with 8GB, 16GB, and 64GB capacities are also on sale, ranging from 44% off to73% off.

Testing new drugs and treatments (for diseases affecting humans) on animal models does not actually work all the time. That’s why we believe that researchers around the world will find the so-called “gut-on-chip” very helpful. Developed by the research team at the Wyss Institute for Biologically Inspired Engineering at Harvard University, the microdevice has the structure, physiology, and mechanics of the human intestine. The new product will allow researchers to study more about intestinal disorders and the safety and effectiveness of treatments.

The gut-on-chip is the size of a USB flash drive and features a flexible, porous membrane, which acts as the intestinal barrier. The membrane is attached to the side walls of a central chamber that stretch and recoil, using a vacuum controller, for recreating peristaltic motions. And a single layer of human intestinal epithelial cells grow on the membrane.

Common intestinal microbes will survive on the surface of the device’s intestinal cells and this quality makes it suitable for studying many diseases and the effects of new treatments.

According to Donald Ingber, who led the research team, “Because the models most often available to us today do not recapitulate human disease, we can’t fully understand the mechanisms behind many intestinal disorders, which means that the drugs and therapies we validate in animal models often fail to be effective when tested in humans. Having better, more accurate in vitro disease models, such as the gut-on-a-chip, can therefore significantly accelerate our ability to develop effective new drugs that will help people who suffer from these disorders“.

This is not the first engineered organ model from the Wyss Institute. They are already famous for their lung-on-a-chip, and have received funds for developing a heart-lung micromachine and a spleen-on-a-chip. Head here to know more about gut-on-a-chip.

SanDisk plans to make 2GB models, right up to 16GB. If you’re interested in the actual specs, it measures 1.63 x 0.69 x 0.29 inches. SanDisk will sell the Cruzer Blade in the US and Canada, a 2GB will cost you $14.99, while a 4GB, 8GB and 16GB will run $21.99, $38.99 and $77.99 respectively.

Although the 8GB is selling for just $16.99 right now at Amazon. I’m not much of a fan of red and black, and if you’re going for the smallest possible, then take a look at the Wink, half the size, straight black, and easier to loose.
