‘Unusually large’ tyrannosaur leg bone points to 10,000-pound behemoth - Popular Science

Tyrannosaurs sit at the top of the food chain in the popular imagination, but a newly described fossil from Alberta, Canada, suggests that a much smaller predator may have fed on the carcass of Albertosaurus sarcophagus, a tyrannosaur relative. Atrociraptor scavenge the carcass of Albertosaurus along the edge of a river floodplain. Image credit: Joshua Adam Doyon.

Two brothers named Gary and Shaggy have helped Cornell University researchers make a rare genetic discovery. In a study published in Scientific Reports, scientists reported the first molecular characterization of Marfan syndrome in domestic cats, a condition primarily recognized in humans. Gary and Shaggy first stood out as kittens because of their unusually long limbs. As they grew older, veterinarians also identified abnormalities in their eye structures and an enlarged aorta, the body's main artery. Together, these symptoms suggested Marfan syndrome, an inherited condition that weakens connective tissues throughout the body. The disorder affects approximately 1 in 4,000 people, but these brothers represented the first known documented feline cases.
