With their ability to help repair damaged muscle, stem cells have shown promise as tools for rebuilding the body's organs, but their potential is yet to be fully realized – especially when it comes to the heart. Part of this is because only a small percentage of stem cells injected actually survive the process, but a newly developed liquid could make life a little easier for freshly transplanted cells. Researchers have found that encapsulating them in a sticky hydrogel gives them the ability to not only survive, but multiply and improve the injured heart's ability to pump blood.
A mechanical hand utilizing DARPA-developed neural technologies has
become the first to allow a paralyzed patient to feel physical
sensations through a prosthesis. The 28 year-old test subject was able
to determine which mechanical finger was being touched whilst
blindfolded, with total accuracy.
Whether it’s slides at playgrounds or roofs of houses, there are some things that you just don’t want to heat up in the sun. Not only does it make them uncomfortable to touch, but it also causes them to age prematurely. While painting such surfaces white is one approach, a scientist at Johns Hopkins University has developed another – reflective paint made from glass.
We’ve already heard about drones being used to deliver pharmaceuticals to patients in remote locations, but scientists from Johns Hopkins University and Uganda’s Makerere University are now looking at the other end of the picture – using them to deliver remotely-located patients’ blood samples to labs in larger centers. According to a proof-of-concept study conducted by the researchers, the little unmanned aircraft should be able to do the job just fine.
And you thought that regular pill bottles were hard to open ... a new
overdose-proof medication dispenser developed by a team of mechanical
engineering students at Johns Hopkins University can't be opened even
with the help of a hammer or drill. It does, however, deliver the proper
dosage at the proper time, as long as the patient uses its built-in
A team of graduate students at Johns Hopkins University has created a prototype device that delivers non-invasive brain stimulation to sufferers of Parkinson's disease. The brain-zapping headwear, dubbed STIMband, helps to reduce the severity of symptoms without requiring a visit to a hospital or doctor's office.
Diabetic retinopathy is one of a number of nasty effects diabetes can have on the human body. The disease sees the development of leaky blood vessels in the eye that over time lead to permanent loss of vision. Though it is the leading cause of new cases of blindness in American adults, its progress can be slowed by certain drugs or laser treatment. But research has now uncovered a new protein found to drive the condition, raising the possibility of preventing it altogether.
If you've ever seen a bat in flight, then you'll know how quickly and
precisely they can maneuver. Scientists from Johns Hopkins University,
Columbia University and the University of Maryland have now uncovered
one of the key factors that allows them to do so – and it could have
applications in the design of aircraft.
