Termination of lethal arrhythmia with light


A research team from the University of Bonn has succeeded for the first time in using light stimuli to stop life-threatening cardiac arrhythmia in mouse hearts. Furthermore, as shown in computer simulations at Johns Hopkins University, this technique could also be used successfully for human hearts.

A data-cleaning tool for building better prediction models


Big data sets are full of dirty data, and these outliers, typos and missing values can produce distorted models that lead to wrong conclusions and bad decisions, be it in healthcare or finance. With so much at stake, data cleaning should be easier.

Plasma – A technology to improve bone healing?


Cold plasma looks like the glow from the "Star Wars" blue light saber but this beam of energy, made of electrons that change polarity at micro-second or nanosecond speeds, could help bones heal faster.

Legions of nanorobots target cancerous tumors with precision


Researchers have developed new nanorobotic agents capable of navigating through the bloodstream to administer a drug with precision by specifically targeting the active cancerous cells of tumours. This way of injecting medication ensures the optimal targeting of a tumour and avoids jeopardizing the integrity of organs and surrounding healthy tissues.

Penn researchers improve computer modeling for designing drug-delivery nanocarriers


Researchers have developed a computer model that will aid in the design of nanocarriers, microscopic structures used to guide drugs to their targets in the body. The model better accounts for how the surfaces of different types of cells undulate due to thermal fluctuations, informing features of the nanocarriers that will help them stick to cells long enough to deliver their payloads.

A thread that collects diagnostic data when sutured into tissue


For the first time, researchers led by Tufts University engineers have integrated nano-scale sensors, electronics and microfluidics into threads - ranging from simple cotton to sophisticated synthetics - that can be sutured through multiple layers of tissue to gather diagnostic data wirelessly in real time, according to a paper published in Microsystems & Nanoengineering.
