Louisiana officials say they’re not sure why there’s been a surge of oily material washing up on the coastline three years after the BP oil spill. The amount is 20 times more than what was found over the same period last year.
A very old squished mosquito found in fossilized rock from Montana. Analysis of the insect's gut revealed telltale chemicals found in blood.
Fossil mosquitoes collected by Dale Greenwalt, a volunteer research collaborator at the Smithsonian National Museum of Natural History.The fossils were collected as part of a 5-year project to produce a research collection of fossil insects from the Kishenehn Formation.
Scientists who study why species vanish are increasingly looking for ancient DNA. They find it easily enough in the movies; remember the mosquito blood in Jurassic Park that contained dinosaur DNA from the bug's last bite? But in real life, scientists haven't turned up multi-million-year-old DNA in any useable form.
Fortunately, a team at the Smithsonian Institution has now found something unique in a 46-million-year-old, fossilized mosquito — not DNA, but the chemical remains of the insect's last bloody meal.
