Taking ultrasound to the molecular level / Acquisizione di ultrasuoni a livello molecolare Segnalato dal Dott.  Giuseppe Cotellessa  /  Reported by Dr. Joseph   Cotellessa Gas vesicles – which can be engineered with proteins to improve ultrasound methods – can help detect specific cell types and create multicolour images (Credit: Barth van Rossum for Caltech) Ultrasound could be used to image cells and molecules deep inside the human body thanks to developments in protein engineering at Caltech in the US. The researchers are said to have engineered protein-shelled nanostructures called gas vesicles – which reflect sound waves – to exhibit new properties useful for ultrasound technologies. The modified gas vesicles were shown to give off more distinct signals, making them easier to image; target specific cell types; and help create colour ultrasound images. In the future, they could be administered to a patient to visualize tissues of interest. “It’s

Metamaterials could mitigate earthquake effects /  I metamateriali potrebbero mitigare gli effetti del terremoto. Segnalato dal Dott. Giuseppe Cotellessa  /  Reported by Dr. Joseph  Cotellessa Large-scale metamaterials can attenuate the energy and amplitude of harmful low-frequency vibrations associated with seismic shocks. This is the conclusion of a European study published in the  New Journal of Physics  that proposes the use of metamaterials in regions threatened by earthquakes. The metamaterials in question are artificial structures that exhibit extraordinary vibrational properties and the study, carried out by a team using detailed computer simulations, shows that large-scale metamaterials can attenuate the energy and amplitude of the low-frequency vibrations that earthquakes deliver. Many large, modern structures including bridges and office blocks are protected against earthquakes through vibration isolation strategies that can be
