Coloured MRI brain scan of abscess in meningitis

Abscess in meningitis. Coloured magnetic resonance imaging (MRI) brain scan of a seven month old baby girl showing a subdural abscess (red, upper left) due to meningitis. The front of the brain (green & yellow), seen in horizontal (axial) section, is at top. The brain's fluid-filled cavities (ventric- les) are red. Meningitis is an inflammation of the membranous meninges (seen as the wavy orange line around the brain) that cover and protect the brain and spinal cord. It is caused by bacterial or viral infection. The abscess has developed in the meninges as a result of the infection. While the viral form is mild, bacterial meningitis is highly dangerous and requires strong antibiotics

Tyrannosaurus rex with meteorites

Dinosaur extinction. Artwork of a Tyrannosaurus rex dinosaur with falling meteorites. The impact of a large meteorite occurred about 65 million years ago at the end of the Cretaceous geological period. The impact was at least partly responsible for the extinction of a wide range of creatures, including the dinosaurs. Estimated to be about 20 km's across, the meteorite struck the Earth in the area now known as the Yucatan peninsula in Central America. It threw vast amounts of debris into the upper atmosphere. The debris blocked out the sunlight causing darkness and lowering global temperatures. The remains of this debris is found as a layer in rocks called the K/T boundary
