The 3D-Lung tumor model helps researchers to test medications (Photo: Fraunhofer IGB)

Researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology in Germany have created a miniature artificial lung that has the potential to significantly improve the process of developing treatments for lung cancer. In addition to the possibility of replacing animal trials currently used to test new medications, the "3D-lung" could be used to expand our understanding of how lung cancer spreads to the rest of the body.  Read More

New research indicates that it may one day be possible for us to regrow teeth ... with som...

Ranking among the X-Men probably isn't all that it's cracked up to be, but who wouldn't want their uncanny ability to regenerate lost bone or tissue? New research into tooth repair and stem cell biology, from a cross-institution team led by David Mooney of Harvard's Wyss Institute, may bring such regeneration one step closer to reality – or at the very least, give us hope that we can throw away those nasty dentures.  Read More

Disabled mice regained the ability to walk less than two weeks after receiving human neura...

When scientists at the University of Utah injected human stem cells into mice disabled by a condition similar to multiple sclerosis, they expected the cells to be rejected by the animals' bodies. It turned out that the cells were indeed rejected, but not before they got the mice walking again. The unexpected finding could have major implications for human MS sufferers.  Read More

Diffuse optical tomography could offer a safer alternative to fMRI and PET scans (Photo: T...

When doctors want to monitor someone's brain activity, they generally use either functional magnetic resonance imaging (fMRI) or positron emission tomography (PET). One subjects the patient to strong magnetic fields, while the other involves radiation exposure. Scientists at Washington University in St. Louis, however, have recently had success using diffuse optical tomography (DOT). Although it may look kind of extreme, it basically just involves shining LEDs into the subject's head.  Read More

A vial of the clear hydrogel turns to a white semi-solid as it's heated to body temperatur...

In the field of regenerative medicine, one of the current areas of interest involves the use of scaffolding-like materials that a patient's own cells can be "seeded" onto. As the cells grow and populate the material, they gradually replace it, until all that remains is a solid piece of tissue or bone. Now, scientists at Houston's Rice University have taken that concept a step further, using a polymer that is liquid at room temperature, but that solidifies into a scaffold when injected into patients' bodies.  Read More

A new technique can detect terahertz waves at room temperature quickly and accurately (Ima...

Researchers at the University of Michigan have found a way to accurately detect electromagnetic waves in the terahertz range by first converting them into sound. The advance opens up new applications ranging from tighter airport security to safer medical imaging.  Read More

Scientists have created functioning human heart tissue that exhibits Barth syndrome  (Imag...

When we've previously heard about "organs on a chip," they've been miniature recreations of healthy organs. If they're being used for research into the treatment of health problems, however, then it only makes sense that those "organs" should have something wrong with them. With that in mind, a group of Harvard scientists have created the world's first lab-grown sample of functioning human heart tissue that has a cardiovascular disease.  Read More

A computer algorithm tracks eyes, ears, and a toy, with the goal of spotting warning sympt...

When experts look back over early home movies of babies later diagnosed with autism, they can see the early behavioral markers of the disorder. The average age of diagnosis, however, is 5 years old. The availability and cost of trained clinicians limits not just early awareness, but also research into autism on a large scale. At Duke University, researchers from different disciplines are using computer vision algorithms to make early diagnosis more likely, and even intend to create an app for parents to use at home.  Read More

Tiny, wirelessly-charged medical devices implanted deep inside the human body could treat ...

Researchers at Stanford University have developed a new way to safely transfer energy to tiny medical devices implanted deep inside the human body. The advance could lead to the development of tiny "electroceutical" devices that can be implanted near nerve bundles, heart or brain tissue and stimulate them directly when needed, treating diseases using electronics rather than drugs.  Read More

Researchers at the Institute of Photonic Sciences (ICFO) have developed a lab-on-a-chip device that can detect protein cancer markers in a drop of blood, working as a very early cancer-detection system. The device can detect very low concentrations of markers and is reliable, cheap and portable, making it attractive for deployment in remote areas of the world.  Read More
