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

Weather is a tricky science—even more so at very high altitudes, with a mix of plasma and neutral particles.

Forensics specialists can use a commercial assay targeting mitochondrial DNA to accurately discriminate between wolf, coyote and dog species, according to a new study from North Carolina State University. The genetic information can be obtained from smaller or more degraded samples, and could aid authorities in prosecuting hunting jurisdiction violations and preserving protected species.

Together with a European team, Senckenberg scientists have presented a new method in the scientific journal BMC Genomics that allows the reliable identification of wolf-dog hybrids on the basis of environmental samples such as feces, hair, or saliva residue. The method has a much higher resolution than conventional methods and is expected to serve as a standard procedure in the future, allowing for comparable detection of hybridization rates across Europe.

The sun provides a daunting source of electromagnetic disarray—chaotic, random energy emitted by the massive ball of gas arrives to Earth in a wide spectrum of radio frequencies. But in that randomness, Stanford researchers have discovered the makings of a powerful tool for monitoring ice and polar changes on Earth and across the solar system.
- Examining mRNA transcription difficultieson July 14, 2021 at 4:02 pm
The corona pandemic has ensured that the term "mRNA" is now also known to a large public beyond laboratories and lecture halls. However, the molecule is much more than an important component of a successful vaccine against the SARS-CoV-2 virus. "mRNAs are a central component of all living things on our planet. Without them life as we know it would not function," says Elmar Wolf.
