Sightings of Albino Flicker at Pike Lake, Saskatchewan

VASP comet sightings

VASP comet sightings ess is more when it comes to actin-fueled propulsion. Julie Plastino, Stéphane Olivier, and Cécile Sykes (Institut Curie, Paris, France) show that hollow actin comets propel beads faster than a more filament-packed comet. Actin comets, which drive bead or bacteria movement, are thought to depend strongly on Arp2/3–built, branched actin networks. Now, Plastino et al. show th...

The mineralogy of arsenic in uranium mine tailings at the Rabbit Lake In-pit Facility, northern Saskatchewan, Canada

A detailed investigation of the mineralogy of As in the tailings of the Rabbit Lake uranium ore processing facility was conducted. The milling/ ore extraction process was sampled at three different locations to obtain information about when, where and under what condition secondary As phases form. These samples were compared with four samples of varying As content from the Rabbit Lake in-pit ta...

Draft Genome Sequence of Rheinheimera sp. KL1, Isolated from a Freshwater Lake in Southern Saskatchewan, Canada

Rheinheimera sp. KL1 was isolated from an algal bloom in Katepwa Lake, Saskatchewan, Canada. The isolate shares genetic and physiological similarities with Rheinheimera tangshanensis. The genome is estimated to be 4,295,060 bp in length with a GC content of 46.37%. Sequence analysis suggests the strain carries a previously uncharacterized prophage.

Deciphering the Age and Significance of the Cora Lake Shear Zone: Athabasca Granulite Terrane, Northern Saskatchewan

Humans perceive flicker artifacts at 500 Hz

Humans perceive a stable average intensity image without flicker artifacts when a television or monitor updates at a sufficiently fast rate. This rate, known as the critical flicker fusion rate, has been studied for both spatially uniform lights, and spatio-temporal displays. These studies have included both stabilized and unstablized retinal images, and report the maximum observable rate as 50...
