A Wireless, Battery-free, Biodegradable Blood Flow Sensor Created

Transforming super-sensitive touch sensors, engineers and medical researchers build a way to wirelessly monitor blood flow after surgery.  A new device developed by Stanford University researchers could make it easier for doctors to monitor the success of blood vessel surgery. The sensor, detailed in a paper published in Nature Biomedical Engineering, monitors the flow of blood through an artery. It is biodegradable, battery-free and wireless, so it is compact and doesn't need to be removed and it can warn a patient's doctor if there is a blockage.

Findings, Graphene-Based Implant Overcomes Technical Limitation

The body of knowledge about the human brain is growing exponentially, but questions big and small remain unanswered. Researchers have been using electrode arrays to map electrical activity in different brain regions to understand brain function. Until now, however, these arrays have only been able to detect activity over a certain frequency threshold.

A new technology developed in Barcelona overcomes this technical limitation, unlocking the wealth of information found below 0.1 Hz and paving the way for future brain-computer interfaces.

Child Healthcare: A Towering Figure in Bangladesh

In recent years, a series of studies by the United Nations and World Bank applauded Bangladesh's efforts in curbing child mortality. In Asia, among the least developed and middle-income countries, words of praise were particularly reserved for Bangladesh.

According to Unicef, the UN children's emergency fund, Bangladesh has done an "outstanding job" of decreasing the rate of child mortality by almost 80% since 1990. The country also has a higher than average annual reduction in child mortality rate at 5.5%.
