"Fortunately, enough previous work has been done on the genetics of wolverines that, if we can get a good enough sample, our colleagues think they can help us identify the population of origin for this individual," Zielinski said. "The historical population of wolverines that once existed in the Sierra Nevada had a very unique and distinct genetic signature. So it should be pretty clear if it's a remnant from that population."
It's important to researchers because the nearest population of wolverines is 900 miles away in Central Washington. That means the animal either migrated across an enormous distance or it's part of a small group of native wolverines that somehow evaded detection for the better part of a century.
Cats have notoriously bad dental problems. Cat owners seldom brush their cats' teeth or scrape the surfaces of the teeth to remove plaque. By the time a cat is 3 or 4 years old, she may already have periodontal disease that can lead to tooth loss. Tooth loss may also come about as a result of tooth breakage, particularly in the canine teeth.
"after each exposure, while the assistants mopped the floor and reclaimed cats, Halsman developed the film to see the progress in the composition. Accidents would happen. The water, intended for the cats, would cover Dali's face instead."
That powder is a substance made from pig bladders called extracellular matrix. It is a mix of protein and connective tissue surgeons often use to repair tendons and it holds some of the secrets behind the emerging new science of regenerative medicine.
"It tells the body, start that process of tissue regrowth," said Badylak.
Badlayk is one of the many scientists who now believe every tissue in the body has cells which are capable of regeneration. All scientists have to do is find enough of those cells and "direct" them to grow.
"Somehow the matrix summons the cells and tell them what to do," Badylak explained. "It helps instruct them in terms of where they need to go, how they need to differentiate - should I become a blood vessel, a nerve, a muscle cell or whatever."
Ed Reingold and Nachum Dershowitz, co-authors of the books Calendrical Calculations and Calendrical Tabulations, determined how often in the period between 1600 and 2400 A.D. Good Friday, Purim, Narouz and the Eid would occur in the same week. The answer is nine times in 800 years. Then they tackled the odds that they would converge on a two-day period. And the total is ... only once: tomorrow. And that's not even counting Magha Puja and Small Holi.
A 2,000-mile journey through the Ross Sea that ended Thursday has also potentially turned up several new species, including as many as eight new mollusks.
It's "exciting when you come across a new species," said Chris Jones, a fisheries scientist at the U.S. National Oceanic and Atmospheric Administration. "All the fish people go nuts about that — but you have to take it with a grain of salt."
The finds must still be reviewed by experts to determine if they are in fact new, said Stu Hanchet, a fisheries scientist at New Zealand's National Institute of Water and Atmospheric Research.
