In a proof of concept study, scientists at Johns Hopkins report they have successfully performed 3D personalised virtual simulations of the heart to accurately identify where cardiac specialists should electrically destroy cardiac tissue to stop potentially fatal irregular and rapid heartbeats in patients with scarring in the heart.

Amputees often experience the sensation of a 'phantom limb'—a feeling that a missing body part is still there. That sensory illusion is closer to becoming a reality thanks to a team of engineers at the Johns Hopkins University that has created an electronic skin. When layered on top of prosthetic hands, this e-dermis brings back a real sense of touch through the fingertips.

When they turn up in pantries or restaurant kitchens, cockroaches are commonly despised as ugly, unhealthy pests. But in the name of science, Johns Hopkins researchers have put these unwanted bugs to work. In a crowded, windowless lab, scholars and students are coaxing the insects to share some crucial locomotion tips that could help future robotic vehicles traverse treacherous terrain.

Some heart disease patients face a higher risk of sudden cardiac death, which can happen when an arrhythmia—an irregular heartbeat—disrupts the normal electrical activity in the heart and causes the organ to stop pumping. However, arrhythmias linked to sudden cardiac death are very rare, making it difficult to study how they occur—and how they might be prevented.

  In a study looking at brain scans of people with mild loss of thought and memory ability, Johns Hopkins researchers report evidence of lower levels of the serotonin transporter -- a natural brain chemical that regulates mood, sleep and appetite.

In a small proof-of-concept study, researchers at Johns Hopkins report that a complex mathematical method to measure electrical communications within the heart can successfully predict the effectiveness of catheter ablation, the standard of care treatment for atrial fibrillation, the most common irregular heartbeat disorder. This has the potential to let physicians and patients know immediately following treatment whether it was effective, or whe...

NASA has moved forward with a plan to develop a refrigerator-sized spacecraft capable of deflecting asteroids and preventing them from colliding with Earth. The Double Asteroid Redirection Test, or DART, is being designed and would be built and managed by scientists at the Johns Hopkins Applied Physics Laboratory. NASA approved a move from concept development to the preliminary design phase on June 23.

  As NASA's Parker Solar Probe spacecraft begins its first historic encounter with the sun's corona in late 2018 - flying closer to our star than any other mission in history - a revolutionary cooling system will keep its solar arrays at peak performance, even in extremely hostile conditions.

Johns Hopkins University scientist Kirby Runyon wants to make one thing clear: Regardless of what one prestigious scientific organisation says to the contrary, Pluto is a planet. So is Europa, commonly known as a moon of Jupiter, and the Earth's moon, and more than 100 other celestial bodies in our solar system that are denied this status under a prevailing definition of "planet."

  Whether or not they aced it in high school, human beings are physics masters when it comes to understanding and predicting how objects in the world will behave. A Johns Hopkins University cognitive scientist has found the source of that intuition, the brain’s “physics engine.”

To make a good framework for filling in missing bone, mix at least 30% pulverised natural bone with some special man-made plastic and create the needed shape with a 3D printer. That’s the recipe for success reported by researchers at The Johns Hopkins University in a paper published April 18th online in ACS Biomaterials Science & Engineering

Desensitisation is a technique that prevents rejection of transplanted kidneys, which means that donors and patients can be much more easily matched. A new study of 1,000 patients shows its promise at changing how organ transplants work. Incompatibility between donor and recipient is the biggest barrier to successful transplants. If the recipient’s immune system attacks the organ, then the transplant fails.

Physicians and biomedical engineers from Johns Hopkins report what they believe is the first successful effort to wiggle fingers individually and independently of each other using a mind-controlled artificial 'arm' to control the movement. The proof-of-concept feat, described online this week in the Journal of Neural Engineering, represents a potential advance in technologies to restore refined hand function to those who have lost arms to injury ...

Researchers at the Johns Hopkins Bloomberg School of Public Health say they have developed tiny 'mini-brains' made up of many of the neurons and cells of the human brain – and even some of its functionality – and which can be replicated on a large scale.

Surgeons at the Johns Hopkins University in Baltimore, Maryland have managed to develop a system wherein a man can move his prosthetic arm by using nothing but the power of thought. The Modular Prosthetic Limb (MPL) is a resounding success, as was the unique method used to attach it.
