wolf : any of several large predatory canids (genus Canis) that are active mostly at night, live and hunt in packs, and resemble the related dogs — Webster
gray wolf : a large, broad-headed, wide-muzzled wolf (Canis lupus) that has a dense, heavy coat of usually light brown or brownish gray interspersed with black above and yellowish white below and that was formerly widely distributed throughout North America and Eurasia but is now greatly restricted to the more northerly parts of its range — Webster
Wolf (Canis lupus), also known as the gray wolf, timber wolf, western wolf, and its other subspecies is a canine native to the wilderness and remote areas of Eurasia and North America. It is the largest extant member of its family, with males averaging 43–45 kg (95–99 lb) and females 36–38.5 kg (79–85 lb). Like the red wolf, it is distinguished from other Canis species by its larger size and less pointed features, particularly on the ears and muzzle. Its winter fur is long and bushy and predominantly a mottled gray in color, although nearly pure white, red, and brown to black also occur. — Wikipedia

SLAC's high-speed 'electron camera' films...
on April 15, 2019 at 3:00 pm
With an extremely fast "electron camera" at the Department of Energy's SLAC National Accelerator Laboratory, researchers have made the first high-definition "movie" of ring-shaped molecules breaking open in response to light. The results could further our understanding of similar reactions with vital roles in chemistry, such as the production of vitamin D in our bodies. […]
Hold the mustard: What makes spiders fussy eaters
on April 15, 2019 at 2:20 pm
It might be one of nature's most agile and calculating hunters, but the wolf spider won't harm an insect that literally leaves a bad taste in its mouth, according to new research by a team of Wake Forest University sensory neuroscientists, including C.J. "Jake" Saunders. […]
Clear sight in the data fog with PAGA
on April 12, 2019 at 11:34 am
Experimental molecular assays with single-cell resolution generate big and complex data. Researchers at Helmholtz Zentrum München and the Technical University of Munich are now presenting their computer algorithm PAGA. They create data-driven, easily interpretable maps that reveal cellular processes and fates in complex contexts. Their paper has been published in Genome Biology. […]
