# astro: the first picture of a black hole at the heart of galaxy Messier 87.

<< We have taken the first picture of a black hole, (..) This is an extraordinary scientific feat accomplished by a team of more than 200 researchers. (..) We have achieved something presumed to be impossible just a generation ago, (..)  Breakthroughs in technology, connections between the world's best radio observatories, and innovative algorithms all came together to open an entirely new window on black holes and the event horizon. >> Sheperd S. Doeleman

<< This breakthrough was announced today in a series of six papers published in a special issue of The Astrophysical Journal Letters.  >>

<< The telescopes contributing to this result were ALMA, APEX, the IRAM 30-meter telescope, the James Clerk Maxwell Telescope, the Large Millimeter Telescope Alfonso Serrano, the Submillimeter Array, the Submillimeter Telescope, and the South Pole Telescope. Petabytes of raw data from the telescopes were combined by highly specialised supercomputers hosted by the Max Planck Institute for Radio Astronomy and MIT Haystack Observatory. >>

# epidem: silent invasions, the case of Candida auris.

<< Bacteria are rebelling  >>

<< The germ, a fungus called Candida auris, preys on people with weakened immune systems, and it is quietly spreading across the globe. >>

<< The recent rate of emergence of pathogenic fungi that are resistant to the limited number of commonly used antifungal agents is unprecedented. The azoles, for example, are used not only for human and animal health care and crop protection but also in antifouling coatings and timber preservation. The ubiquity and multiple uses of azoles have hastened the independent evolution of resistance in many environments. One consequence is an increasing risk in human health care from naturally occurring opportunistic fungal pathogens that have acquired resistance to this broad class of chemicals. >>

# acad: oops! the scientific world is abuzz ... scientists first and foremost should "embrace uncertainty" and "be thoughtful, open and modest." ...

<< The scientific world is abuzz following recommendations by two of the most prestigious scholarly journals – The American Statistician and Nature – that the term "statistical significance" be retired. In their introduction to the special issue of The American Statistician on the topic, the journal’s editors urge "moving to a world beyond 'p<0.05,'" the famous 5 percent threshold for determining whether a study’s result is statistically significant.  (..) scientists first and foremost should "embrace uncertainty" and "be thoughtful, open and modest." >>
