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

- How reindeer eyes transform in winter to give...on July 1, 2022 at 1:49 pm
Reindeer are loved the world over for their dark, expressive eyes, majestic antlers and magical association with Santa Claus. The moment you learn the cold, hard truth of how Christmas presents arrive under the tree is a harrowing one that blights many a childhood. But reindeer are more special than your cynical older sibling or classmates would have had you believe.

A team of researchers affiliated with several institutions in the U.S. reports a high percentage of red wolf genes in the genomes of coyote hybrids living in some parts of southwest Louisiana and eastern Texas. In their paper published in the journal Science Advances, the group describes the find as a possible means of saving red wolves from extinction.
- Ice Age wolf DNA reveals dogs trace ancestry to...on June 29, 2022 at 3:00 pm
An international group of geneticists and archaeologists, led by the Francis Crick Institute, have found that the ancestry of dogs can be traced to at least two populations of ancient wolves. The work moves us a step closer to uncovering the mystery of where dogs underwent domestication, one of the biggest unanswered questions about human prehistory.

Life (as we know it) is based on carbon. Despite its ubiquity, this important element still holds plenty of secrets, on earth and in the heavens above us. For example, astrophysicists like Columbia's Daniel Wolf Savin who study interstellar clouds want to understand how the chemicals, including carbon, swirling within these nebulous aggregations of gas and dust form the stars and planets that dot our universe and give rise to organic life.
