Monster Machines: The World's Strongest MRI Will Be Able To Pick Up A Tank

The stronger an MRI machine’s magnetic field is, the better image resolution and refresh rates it is able to achieve. While most medical-grade MRIs today top out between 1.5 and 3 Tesla, the unit measure of magnetic field strength, GE has recently constructed a unit with the whopping power of 7 Tesla. But that’s nothing compared to the power of the INUMAC.


Life-Saving App Knows How Much Blood You Lost Just Looking At A Sponge

During a surgery, doctors and surgeons use a measurement called EBL — or estimated blood loss — to determine how much blood a patient has lost, and how much needs to be returned via a transfusion. Unfortunately it’s really just an educated guess, until Gauss Surgical’s new Triton Fluid Management System makes its way into operating rooms.


The Bug That Lost A Few Genes To Become The Black Death

About 6000 years ago, a bacterium underwent a few genetic changes. These allowed it to expand its habitat from the guts of mice to that of fleas. Such changes happen all the time, but in this particular instance the transformation eventually resulted in the Black Death that wiped out a third of Europe’s population in the 14th century.


A Battery-Free, Pocket-Sized CPR Coach Ensures You're Really Helping

It might look easy, but properly performing CPR to save someone’s life — and not injure them in the process — does require a specific technique. Since not everyone has taken a first-aid course, the Cardio First Angel serves as an impromptu CPR instructor that ensures you’re doing it right, no matter how limited your medical know-how might be.


Australian Researchers May Have Found A Way To Regenerate Body Parts, And It Involves Seaweed

Seaweed could be the answer to regenerating bone and tissue in treatments for diseases such as cancer and schizophrenia.


This Student-Designed Ventilator Is 80 Times Cheaper Than The Norm

Babies born premature or sick are often completely reliant on a ventilator to stay alive. In many parts of the world that’s a $40,000 machine that runs completely autonomously, but in developing nations it’s often the child’s parents — continuously squeezing a hand pump. It’s a depressing image that inspired students at Brigham Young University to design a portable ventilator that costs just $500 to build.


An Insulin Pen Cap That Reminds Diabetics When Their Last Injection Was

As if all the side effects and health concerns related to diabetes weren’t enough, those dealing with the condition also have to maintain a frequent and carefully tracked regiment of insulin injections. Missing even one can be incredibly dangerous, which is what inspired one company to create the Timesulin.


One Day, Your Smartphone's Screen Could Be Used To Test Blood

Patients who rely on the use of coagulants to limit the formation of blood clots in their veins also require frequent and regular trips to the hospital for tests to monitor their blood flow. It’s a time-consuming side effect that researchers at EPFL hope they have solved with a portable test that relies on a smartphone’s display’s unique properties.


A Simple Adaptor Lets The iPhone Assist In Eye Exams

We’ve already got machines that give ophthalmologists a close-up view of the inside and outside of the human eye. The problem is they’re big and heavy, expensive, and rarely accessible to those in third world nations. So researchers at Stanford University have created a simple iPhone add-on that lets almost anyone, anywhere, perform eye exams.


How Implants And Prosthetic Limbs Get Recycled And Reused

Every year, millions of pacemakers, metal hips and prosthetics outlast the bodies they’re designed for. But these medical devices could very well go on to have a second-life — in cars, wind turbines, and even another person.
