# life: i tremiti (vortici?) previsionali di Giancarlo, by Alessandra Paola

<< Giancarlo Giorgetti, sottosegretario di Palazzo Chigi nel governo di Giuseppe Conte, pare abbia detto ai leghisti presenti nell' esecutivo di tenere una foto di Matteo Renzi come monito sulla scrivania. Per non dimenticare che quattro anni fa il Pd aveva conseguito il 40%, pari a 11 milioni di voti, alle elezioni europee >>

# gst: to model a system that can "collapse without warning"

<< Volcanoes progressively weaken and may collapse without warning through hydrothermal alteration. These dangerous mass wasting processes occur less-frequently than eruptions or lahars but the resultant mass flows can be large in size, posing risk to local residents, and businesses. >>

<< Collapses are often multi-hazard events, with even small-scale landslides capable of triggering eruptions or creating break-out lahars. >>

<< These kind of events demonstrated the greater need to understand and assess this process >>

# gene: newtic1 to regenerate limbs

<< The newt, a group of urodele amphibians, has outstanding ability to repeatedly regenerate various body parts >>

<< In this animal, when the limb is amputated, a cell mass named the blastema appears on the stump and eventually gives rise to a new functional limb >>

AA << identified an orphan gene Newtic1, whose transcripts significantly increased in the blastema. Newtic1 was expressed in a subset of erythrocytes that formed a novel clump (EryC) >>

<< When the limb was amputated, EryCs were newly generated in the stump and accumulated into a distal portion of the growing blastema. >>

# geo: low frequency sounds that resemble the shape of the tornillo seismic waves

<< This infrasound waveform is a slowly decaying sinusoid with exceptional low‐frequency (..) and high quality factor (..) and resembles the shape of tornillo seismic waveforms. >>

# archeol: on the ancient turquoise

<< turquoise used by the Aztecs and Mixtecs likely derives from Mesoamerican sources and was not acquired through long-distance exchange with the Southwest >>

Alyson M. Thibodeau, Leonardo Lopez Lujan, et al. Was Aztec and Mixtec turquoise mined in the American Southwest?  Science Advances. Jun 13,  2018; 4 (6), eaas9370. doi: 10.1126/sciadv.aas9370

http://advances.sciencemag.org/content/4/6/eaas9370

<< This work revises our understanding of these relatively rare objects and provides a new perspective on the availability of turquoise, which was a highly valued luxury resource in ancient Mesoamerica >>

<< These findings potentially re-shape our understanding of both the nature and extent of long-distance contacts between Mesoamerican and Southwestern societies (..) I hope this inspires people to be skeptical of claims >> Alyson Thibodeau.
