Competition from other bears may threaten a polar bear population Biologists affiliated with the American Museum of Natural History and City College of the City University of New York have found that grizzly bears are roaming into what was traditionally thought of as polar bear habitat"”and into the Canadian province of Manitoba, where they are officially listed as extirpated. The preliminary data was recently published in Canadian Field Naturalist and shows that sightings of Ursus...

New simulation presented at astronomy meeting reveals planet migration prevents plunge into sun For the last 20 years, the best models of planet formation"”or how planets grow from dust in a gas disk"”have contradicted the very existence of Earth. These models assumed locally constant temperatures within a disk, and the planets plunge into the Sun. Now, new simulations from researchers at the American Museum of Natural History and the University of Cambridge show that variations...

Two New York City high school students exploring their homes using the latest high-tech DNA analysis techniques were astonished to discover a veritable zoo of 95 animal species surrounding them, in everything from fridges to furniture, from sidewalks to shipping boxes, and from feather dusters to floor corners. Guided by DNA "barcoding" experts at The Rockefeller University and the American Museum of Natural History, Grade 12 students Brenda Tan and Matt Cost of Trinity School, Manhattan,...

A new look at limbs changes understanding of early carnivore locomotion More than a hundred years after its discovery, the limbs and vertebrae of a fossil have been pulled off the shelf at the American Museum of Natural History to revise the view of early carnivore lifestyles. Carnivores"”currently a diverse group of mostly meat-eating mammals like bears, cats, raccoons, seals, and hyenas"”had been considered arboreal in their early evolutionary history. But now that the skeleton...

A team of paleontologists has unearthed a previously unknown meat-eating dinosaur from a fossil bone bed in northern New Mexico. The discovery settles a long-standing debate about early dinosaur evolution, and reveals a period of explosive diversification.  It also hints at how dinosaurs spread across the supercontinent Pangaea. A description of the new species, named Tawa after the Hopi word for the Puebloan sun god, appears in the Dec. 10 issue of the journal Science. The...

Project 1640 sees the unknown using a novel technique known to Galileo Next time you spy the Big Dipper, keep in mind that there is another star, invisible to the unaided eye, contributing to this constellation. According to a new paper published in The Astrophysical Journal, one of the stars that makes the bend in the ladle's handle, Alcor, has a smaller red dwarf companion. Newly discovered Alcor B orbits its larger sibling and was caught in the act with an innovative technique called...

While most of us would never willingly consume a highly endangered species, doing so might be as easy as plucking sushi from a bento box. New genetic detective work from the Sackler Institute for Comparative Genomics at the American Museum of Natural History shows that bluefin tuna is routinely plated in sushi bars sampled in New York and Colorado. A quarter of what was labeled as tuna on sushi menus was bluefin, and some was even escolar, a waxy, buttery fish often labeled "white tuna" that...

DNA from more than 1,500 whales examined After 15 years of research in the waters of the South Atlantic and Indian Oceans, scientists from the Wildlife Conservation Society, the American Museum of Natural History, and an international coalition of organizations have unveiled the largest genetic study of humpback whale populations ever conducted in the Southern Hemisphere. By analyzing DNA samples from more than 1,500 whales, researchers can now peer into the population dynamics and...

Tipping point in planet formation found by new simulations Some stars are lonely behemoths, with no surrounding planets or asteroids, while others sport a skirt of attendant planetary bodies. New research published this week in The Astrophysical Journal Letters explains why the composition of the stars often indicates whether their light shines into deep space, or whether a small fraction shines onto orbiting planets. When a star forms, collapsing from a dense cloud into a luminous ball, it...

Carnivorous but smaller T. rex relative shared environment with larger cousins Now, just a few weeks after tiny, early Raptorex kriegsteini was unveiled, a new wrench has been thrown into the family tree of the tyrannosaurs. The new Alioramus altai"”a horned, long-snouted, gracile cousin of Tyrannosaurus rex"”shared the same environment with larger, predatory relatives. A paper published this week in the Proceedings of the National Academy of Sciences describes this exceptionally...

Edwin Harris Colbert (September 28, 1905 – November 15, 2001), known as “Ned” to his friends and colleagues, was a distinguished American Paleontologist. He helped popularize the study of dinosaurs through his prolific research, writings, and 40 years of work as a curator at the American Museum of Natural History in New York. Colbert was born in Clarinda, Iowa, but moved to Maryville, Missouri during infancy. Like many young children, and most of his predecessors and contemporaries,...

Barnum Brown (February 12, 1873 – February 5, 1963) was an American Paleontologist best known for his contributions to the American Museum of Natural History, and his discovery of the first documented Tyrannosaurus rex remains. Brown was known less as a published paleontologist and more often as an energetic excavator, perhaps the greatest fossil collector of all time. Barnum Brown was born in Carbondale, Kansas, and was named after P.T. Barnum – of traveling circus fame, but no...
