ASTRI Mini-Array core science at the Observatorio del Teide

Something rotten at the core of science?

A recent U.S. Supreme Court decision and an analysis of the peer review system substantiate complaints about this fundamental aspect of scientific research. Far from filtering out junk science, peer review may be blocking the flow of innovation and corrupting public support of science. The U.S. Supreme Court has recently been wrestling with the issues of the acceptability and reliability of sci...

Dynamics of the upper solar photosphere

The dynamics of the upper solar photosphere was studied by using 1-D photospheric line spectrograms obtained using the VTT of the Observatorio del Teide. Three spectral lines with line core formation heights between 250 and 500 km were analyzed. It is clearly seen that at these levels the velocity and intensity fields are highly correlated but different from the lower lying zone where convectiv...

Scaling behavior of the vertical velocity field in the solar photosphere

We analyze, for the first time, the scaling behavior of the photospheric vertical velocity field. Our analysis is based on data collected by the Italian Panoramic Monocromator (IPM) mounted at the THEMIS telescope at the Spanish “Observatorio del Teide” (Tenerife) of the Instituto de Astrofisica de Canarias. We investigate the occurrence of scaling in the cancellations between downflow and upfl...

Assembly of a Mini-Chemostat Array.

Here, we describe instructions for the assembly of an array of miniature (20-mL) chemostats or "ministats" built from relatively inexpensive off-the-shelf parts. In experiments with yeast cultures, we have observed reproducibility in cellular physiology, gene expression patterns, and evolutionary outcomes with different ministats as well as between ministats and commercial large-volume platform...
