Toxic air pollution nanoparticles discovered in the human brain

Toxic air pollution nanoparticles discovered in the human brain

A team involving Oxford University scientists has, for the first time, discovered tiny magnetic particles from air pollution lodged in human brains – and researchers think they could be a possible cause of Alzheimer’s disease.

  • P53, which helps healthy cells prevent genetic mutations, is missing from about half of all tumors. Researchers have found that a backup system takes over when p53 is disabled and encourages cancer cells to continue dividing. In the background of this illustration are crystal structures of p53 DNA-binding domains.

The world’s tiniest temperature sensor is powered by radio waves

The world’s tiniest temperature sensor is powered by radio waves

 

Researchers at TU/e have developed a very tiny wireless temperature sensor that is powered in a very special way: from the radio waves that are part of the sensor’s wireless network. This means that the sensor needs not even a single wire, nor a battery that would have to be replaced. The arrival of such sensors is an important development on route towards smart buildings, for instance. But the applications are many and various.

A microfluidic sonication device for the production of coated microbubbles

 

The Oxford Team has developed a platform technology that could be used in a clinical setting to produce microbubbles employed as contrast agents in ultrasound imaging or as drug delivery vehicles. The technology also has other applications including foods, paints, biofuels and cosmetic products.
