Scientists on Wednesday announced the discovery of the fossil of the oldest known horned dinosaur species from North America.
It was a dinosaur about the length of a crow and the weight of a bunny. But this modest plant-eater that lived about 108 million years ago in southern Montana foreshadowed the monstrous horned dinosaurs that trod North America millions of years later. Scientists on Wednesday announced the discovery of the fossil of the oldest known horned dinosaur species from North America, , that was a close cousin to similar dinosaurs from Asia. Reuters
American researchers have discovered a genetic mutation that aided the spread of breast cancer in a patient, an exciting discovery that may provide guidance on how to treat women with the disease in the future. A team of researchers from the University of Pittsburgh Cancer Institute and the Magee-Womens Research Institute used tumour tissue samples collected over the last two decades that allowed researchers to track the spread of the disease in six patients. All six patients had surgery to remove the initial tumour, and were determined to be disease free, only to have the cancer recur and ultimately kill them. Recurrence of breast cancer after surgery occurs in about 30 per cent of patients. Tribune News Service
