Government video lets you choose your own clinical research (mis)adventure

It seems hardly a day goes by without a new report of research misconduct. To help prevent such behavior from occurring, the US Department of Health and Human Services has released an  interactive training video called ‘The Research Clinic’ that gives viewers the opportunity to assume the role of one of four decision-makers who are frequently involved in clinical research: a principal investigator, a clinical research coordinator, a research assistant and the chair of an institutional review board.  Read more

‘FlyWalker’ tracks insect feet, could advance Parkinson’s research

They may have wings, but fruit flies spend plenty of time on their feet. And these insects, also known as Drosophila, are a standard animal model for studying neurodegenerative diseases, such as Parkinson’s and even Alzhiemer’s.  Read more

MIT video models airports most likely to spread diseases

In a study released today from Massachusetts Institute of Technology (MIT) based in Cambridge, Massachusetts, engineers show through computer modeling how major international US airports might contribute to the spread of contagious disease during the early days of an epidemic. The culprits that could contribute the most damage turn out to be airports in New York, Los Angeles and Honolulu, Hawaii. “Our work is the first to look at the spatial spreading of contagion processes at early times, and to propose a predictor for which ‘nodes’ — in this case, airports — will lead to more aggressive spatial spreading,” said MIT computer engineer Ruben Juanes in a statement. The new model, unlike previous ones, considers the routines that passengers usually follow when traveling, an airport’s geographic location, how flights connect–or don’t–between airports, and, finally, how a long wait at an airport could influence how diseases spread.  Read more

Dual device reveals blocked arteries with fine-scale molecular and anatomical detail

A new probe that can image both the structural anatomy of artery walls as well as the biological activities within them could one day help detect blood clots before they cause problems. “Now we’re going to be able to more precisely predict which plaques are going to cause symptoms and heart attacks and sudden cardiac death,” says Farouc Jaffer, director of the Cardiovascular Molecular Imaging Program at the Massachusetts General Hospital’s Center for Molecular Imaging Research in Boston. Stent-related clotting, which often leads to full-blown heart attacks, occurs in at least 2% of people who have the tubes implanted into  … Read more
