In situ measurements of intracellular thermal conductivity using heater-thermometer hybrid diamond nanosensors

Posted by in categories: biotech/medical, nanotechnology

Understanding heat dissipation processes at nanoscale during cellular thermogenesis is essential to clarify the relationships between the heat and biological processes in cells and organisms. A key parameter determining the heat flux inside a cell is the local thermal conductivity, a factor poorly investigated both experimentally and theoretically. Here, using a nanoheater/nanothermometer hybrid made of a polydopamine encapsulating a fluorescent nanodiamond, we measured the intracellular thermal conductivities of HeLa and MCF-7 cells with a spatial resolution of about 200 nm. The mean values determined in these two cell lines are both 0.11 ± 0.04 W m−1 K−1, which is significantly smaller than that of water. Bayesian analysis of the data suggests there is a variation of the thermal conductivity within a cell.

Using plasma technology to feed the world

Posted by in category: sustainability

Using state-of-the-art plasma technology to make cheap fertilizer for small farmers may sound like magic, but it has now become reality. Researchers at Eindhoven University of Technology (TU/e) have built a small plasma-powered plant that produces nitrogen-based liquid fertilizer only using sun, water and air. “The plant is easy to set up, sustainable and very efficient,” says TU/e researcher Fausto Gallucci, who together with partners in Africa, Germany and Portugal has done successful tests of the device in Uganda. “We now want to bring the mini-plant to the market, so that it becomes available to farmers around the world.”

UK plans to launch $1.1 billion ‘high-risk, high-reward’ science research agency

Posted by in categories: innovation, science

ARIA’s launch comes hot on the heels of the European Innovation Council’s new fund, which stands at $12 billion. The EIC was set up by the European Commission, the EU’s executive arm, to try to help start-ups across Europe to scale up and compete with rivals in the U.S. and Asia, which have spawned several tech giants with market caps that run well into hundreds of billions of dollars.


The Advanced Research and Invention Agency (ARIA) will fund “high-risk, high-reward” scientific research in the hope of achieving “groundbreaking” discoveries.

A Longtime Educator Says K-12 Schools Need To Encourage Creativity And Curiosity

Posted by in categories: education, innovation

It is about time to revisit our assumptions about the public school system. What should be the goal of school education?


If we want to change a classroom to embrace innovation and questioning, we need the leaders and the school system as a whole to embrace innovation and questioning.
