Helicobacter Pylori bacteria, fluorescing green

Research carried out by a team of scientists at the University of Southern Denmark literally sheds new light on how a non-invasive technique for the early diagnosis of stomach ulcers could be performed in the future. The findings of the researchers point to a fast, hassle-free method that does not require sample tissues, unlike current testing methods.  Read More

HLAA sets to an elastic consistency, and bonds with cardiac tissue

A hole in the heart is never a good thing, so when an infant is born with such a defect, doctors have to act quickly to fix it. Unfortunately, both sutures and staples can damage the heart tissue, plus it takes too long to apply sutures. Existing surgical adhesives have their own drawbacks in that they can be toxic, and they typically become unstuck in wet, dynamic environments such as the heart. As a result, infants often require subsequent operations to "replug" the hole. Now, however, scientists have developed a sort of superglue for the heart, that quickly and securely bonds patches to holes.  Read More

The ZIO Patch is worn on the chest for up to two weeks (Photo: Scripps)

Ordinarily, when doctors wish to monitor an ambulatory patient for heartbeat irregularities, they have them wear what is know as a Holter monitor. The device is fairly cumbersome, so it's usually worn for no more than 24 hours. A recent study, however, indicates that the relatively new ZIO Patch provides more accurate readings, while being considerably less obtrusive.  Read More

The University of Queensland mini-kidney

Instead of having to wait for one of the limited number of available donor kidneys, patients in need of a transplant may eventually be able to have a new kidney custom-grown for them. That possibility recently took one step closer to reality, as scientists at Australia's University of Queensland successfully grew a "mini-kidney" from stem cells.  Read More

Renderings of an implanted Carmat artificial heart

Last Wednesday in Paris, a 75 year-old man received an artificial heart. That in itself might not be newsworthy, as such devices have been in use since the early 80s. In this case, however, the gadget in question was the first Carmat bioprosthetic artificial heart to ever be implanted in a human. According to its inventor, cardiac surgeon Alain Carpentier, it's the world's first self-regulating artificial heart.  Read More

One of two versions of MIT's prototype portable scanner

If you're like a lot of people, you don't make an annual trip to the ophthalmologist to get your eyes checked ... and you really ought to, in order to catch any problems before it's too late. If it were possible to get them checked at a regular doctor's office or clinic, though, perhaps you might do so more often. That's one of the reasons that a team at MIT have designed a new hand-held retinal scanner, that can quickly and easily be used anywhere.  Read More

Orally-ingested insulin layersomes could eventually replace injections  (Photo: Shuttersto...

Help could be on the way for the hundreds of millions of diabetics who are tired of giving themselves daily insulin injections. Scientists from India's National Institute of Pharmaceutical Education and Research have recently had success in orally delivering insulin to rats' bloodstreams.  Read More

Cells from rats' retinas have been successfully jetted from an inkjet printer (Photo: Shut...

Imagine if conditions that presently cause blindness could be treated by simply by fabricating new tissue, and using it to replace the defective part of the retina. We may not be at that point yet, but we've definitely taken a step closer, thanks to research being conducted at the University of Cambridge. Scientists there have successfully used an inkjet printer to "print" rats' retinal cells onto a substrate, paving the way for the creation of custom-made eye-repair material.  Read More

NTU Prof Peter Preiser and scientist Dr Annie Gao

A new discovery by scientists from Singapore‚Äôs Nanyang Technological University (NTU) holds promise for the development of a Malaria vaccine. The result of five years research, the breakthrough is based on the ability to block the invasion of red blood cells by the deadly parasite.  Read More

The BioPen lets surgeons 'draw' live cells and growth factors directly onto the site of an...

Devices like the 3Doodler and SwissPen literally put 3D printing technology in the hands of consumers, but a new BioPen developed at the University of Wollongong in Australia is targeted at more skilled hands. The handheld device is designed to let surgeons "draw" live cells and growth factors directly onto the site of an injury to help accelerate the regeneration of functional bone and cartilage.  Read More
