'Body on a chip' could improve drug evaluation


MIT engineers have developed new technology that could be used to evaluate new drugs and detect possible side effects before the drugs are tested in humans.

Spreading antibiotic-resistances: rapid test helps with administering the "correct" drug


Multi-resistent microbes are a growing danger. The often unnecessary and mass use of antibiotics causes the impassivity of pathogens against drugs. Infections that were easily curable up to now, may become life threatening. In just three hours, a new rapid test will give information on which available antibiotic is still effective in a concrete case.

Scientists develop new tool for imprinting biochips


The new technology could allow researchers to fit more biochemical probes onto a single biochip and reduce the cost of screening and analyzing changes associated with disease development, detecting bioterrorism agents, and other areas of research.

Why the world looks stable while we move


Every head movement changes the image of our environment that enters our eyes. We still perceive the world as stable, because our brain corrects for any changes in its visual information due to those head movements.

Revolutionizing Cancer Research with Diamond


Magnetic resonance imaging (MRI) is being revolutionized: With the nanodiamond the tumor tissue can be detected sooner and distinguished better from the healthy surrounding tissue.

Comparison shows value of DNA barcoding in selecting nanoparticles


The first direct comparison of in vitro and in vivo screening techniques for identifying nanoparticles that may be used to transport therapeutic molecules into cells shows that testing in lab dishes isn't much help in predicting which nanoparticles will successfully enter the cells of living animals.

A gentle approach treating microbial keratitis


Microbial infections of the cornea can have serious consequences, including blindness in the worst case. The treatment of keratitis, a condition caused by certain pathogens, always presents major challenges to ophthalmologists. These corneal infections frequently cannot be successfully treated with the therapies currently available.

Maelstroms in the heart


Every five minutes in Germany alone, a person dies of sudden cardiac arrest or fibrillation, the most common cause of death worldwide. This is partly due to the fact that doctors still do not fully understand exactly what goes on in the heart during the occurrence. Until now, it was impossible to visualize dynamic processes in the fibrillating heart muscle, or myocardium.
