A patient suffering from heart failure reportedly coughed up a huge blood clot that somehow retained the shape of the lung passages it had blocked. The Atlantic's Haley Weiss reports that "Doctors Aren’t Sure How This Even Came Out of a Patient"
In Wieselthaler’s case, blood eventually broke out of his patient’s pulmonary network into the lower right lung, heading directly for the bronchial tree. After days of coughing up much smaller clots, Wieselthaler’s patient bore down on a longer, deeper cough and, relieved, spit out a large, oddly shaped clot, folded in on itself. Once Wieselthaler and his team carefully unfurled the bundle and laid it out, they found that the architecture of the airways had been retained so perfectly that they were able to identify it as the right bronchial tree based solely on the number of branches and their alignment.
He died a few days later. I looked it up. Sorry.
Biomedical engineers prototyped a pill that integrates a syringe to inject insulin into the floor of the stomach. From Science News: The shape is designed to guide the device to rest, cap down, on the floor of the stomach. There, it sticks a needle tip composed almost entirely of insulin a few millimeters into the […]
Smart toilets that analyze urine and poop in the bowl have been demonstrated for years, but now Rochester Institute of Technology engineers have integrated multiple kinds of biosensors into the toilet’s seat. The WiFi-enable systems tracks EEG, blood oxygen levels, and the heart’s pumping force. From IEEE Spectrum: If the monitoring system works as expected, […]
Continuing the quest to design robots that could travel through our bodies to deliver drugs and cure disease, researchers at EPFL and ETH Zurich demonstrated tiny shape-shifting microrobots that swim through blood vessels. Made from hydrogel nanocomposites, the microbots can fold into various shapes for easy travel through tight spaces and flowing with dense, viscous, […]
What do Facebook, Twitter, YouTube and Google all have in common? Somewhere in their framework, they all use MySQL, that most versatile (and free!) of database management systems. And they’re not alone. If your company or the one you’d like to work for wrangles data (and who doesn’t?), they’re going to need someone with a […]
There’s a reason you’re hearing about the gig economy in every other business story these days. More than ever, people are finding income from more than one source. And if you find the right one, a side hustle can do more than just pad your pockets – it can allow you to finally get paid […]
High-def cameras are available to anyone and for much less than they were just a decade ago. Even the phones in our pockets can be used to shoot and edit short films. It’s never been easier to be a filmmaker, providing you have the technique. Enter the Film & Cinematography Mastery Bundle, an online boot […]
