One Comment23 June 2011

orca-1Stanford researchers have developed a highly sensitive underwater microphone which is modeled after the extraordinarily acute hearing of orcas. The microphone can capture a wide range of ocean sounds in a range of approximately 160 decibels, significantly more than existing underwater microphones (hydrophones) which have limited ranges of sensitivity and do not perform well at… »

20 June 2011

tudelft-nanoporeResearchers at Delft University of Technology and the University of Basel have created a biomimetic nanopore that provides a unique test and measurement platform for the way that proteins move into a cell’s nucleus. The biomimetic pore is fully functional and able to act selective, thus it can be used as a testing platform for… »

knee-cartilage_0Millions of people with knee injuries could benefit from a new type of stem cell bandage treatment if clinical trials prove successful. The world’s first clinical trial for the treatment of patients with torn meniscal cartilage has received approval from the MHRA (UK regulatory agency). The current treatment for the majority of tears is the… »

2 Comments10 June 2011

flash-bainite-steel-1A Detroit entrepreneur surprised university engineers when he invented flash processing – a heat-treatment process which lasts only 10 seconds and it makes steel stronger and more shock-absorbing than the most common titanium alloys used by industry. Now the entrepreneur is working with researchers at Ohio State University (OSU) to better understand the science behind… »

Using solar power to clean up industrial oxidation reactions

By Rob Aid
9 June 2011

kevin-moeller-using-solar-power-to-clean-up-industrial-oxydation-reactions-1A group of researchers from Washington University in St. Louis came up with an idea to combine two existing technologies in order to clean up industrial oxidation reactions. They are using photovoltaic cells to power electrochemical reactions to eliminate the toxic byproducts of reactions commonly used in chemical synthesis — and with them the environmental… »
