It lurks in hospitals and nursing homes, surviving cleaning crews’ attempts to kill it by holing up in a tiny, hard shell. It preys upon patients already weak from disease or advanced age.

It looks like a real heart. And this is the goal of the first entirely soft artificial heart: to mimic its natural model as closely as possible. The silicone heart has been developed by Nicholas Cohrs, a doctoral student in the group led by Wendelin Stark, Professor of Functional Materials Engineering at ETH Zurich. The reasoning why nature should be used as a model is clear. Currently used blood pumps have many disadvantages: their mechanical parts are susceptible to complications while the patient lacks a physiological pulse, which is assumed to have some consequences for the patient.

RMIT scientists in Melbourne have led an international collaboration that potentially unlocks better treatment of viral diseases, including the flu and common cold.

A new model based on measuring stress from daily hassles may help forecast future migraine headache attacks in those who develop them frequently. The findings, which are published in a Headache study, suggest that it may be possible to predict the occurrence of tomorrow’s migraine attack based on today’s stress.

In a tiny room in the sub-basement of MIT’s Building 66 sits a customized, super-resolution microscope that makes it possible to see nanoscale features of a red blood cell. Here, Reginald Avery, a fifth-year graduate student in the Department of Biological Engineering, can be found conducting research with quiet discipline, occasionally fidgeting with his silver watch.

He spends most of his days either at the microscope, taking high-resolution images of blood clots forming over time, or at the computer, reading literature about super-resolution microscopy. Without windows to approximate the time of day, Avery’s watch comes in handy. Not surprisingly for those who know him, it’s set to military time.

Doctors can’t predict who will develop Type 1 diabetes, a chronic autoimmune disease in which one’s own immune system destroys the cells needed to control blood-sugar levels, requiring daily insulin injections and continual monitoring.

Changes in the visual systems of newly diagnosed Parkinson’s disease patients may provide important biomarkers for the early detection and monitoring of the disease, according to a new study published online in the journal Radiology.

In their work toward 3-D printing transplantable tissues and organs, bioengineers and scientists from Rice University and Baylor College of Medicine have demonstrated a key step on the path to generate implantable tissues with functioning capillaries.

Many scientists are paying new attention to prebiotics, that is, molecules we eat but cannot digest, because some may promote the growth and health of beneficial microorganisms in our intestines, says nutritional microbiologist David Sela at the University of Massachusetts Amherst. In a new study, he and colleagues report the first evidence that certain beneficial gut bacteria are able to grow when fed a carbohydrate found in cranberries and further, that they exhibit a special nontypical metabolism.

Why do some people prefer stable, predictable lives while others prefer frequent changes? Why do some people make rational decisions and others, impulsive and reckless ones? UCLA behavioral neuroscientists have identified changes in two brain regions that may hold answers to these questions.
