Blood-based DNA marker tracks arsenic exposure and may predict toxicity risk

Solar radio bursts are intrinsically linked to the motion of their emitting source through the coronal and heliospheric plasma. Electron transport is mostly confined to magnetic field lines. These electrons move at a substantial fraction of the speed of light and often generate radio emission via the plasma emission process.

Exoplanet science and the search for life beyond Earth continue to advance at break-neck speeds, with the number of confirmed exoplanets by NASA rapidly approaching 6,300, with 223 of those exoplanets being designated as terrestrial (rocky) exoplanets. With the promise of discovering an increasing number of Earth-sized exoplanets increasing every day, new telescopes from across the world have the opportunity to contribute to this incredible field.

The Eurovision Song Contest (ESC) has been attracting millions of fans every year since it was launched back in 1956. At the same time, it represents a unique opportunity for research. Almost no other major cultural event has been so well documented over such an extended period of time. Data on songs, voting and rule changes is freely accessible, making Eurovision an ideal example for computer-assisted social sciences of a data-based culture system.

Scientists at Université de Montréal's Institute for Research in Immunology and Cancer have developed a new database that integrates the molecular structure of microRNAs and messenger RNAs to systematically model their interactions. Called RIMap-RISC and developed by Ph.D. student Simon Chasles in the laboratory of UdeM professor François Major, director of IRIC's RNA engineering research unit, the database is detailed in a study published in Genome Biology.
