This mosaic image from NASA's Dawn spacecraft, captured between 2011 to 2012, shows the giant asteroid Vesta. The mountain at the south pole, seen at the bottom of the image, is more than twice the height of Mount Everest.

A few years ago, cognitive scientist Duje Tadin and his colleague Randolph Blake decided to test blindfolds for an experiment they were cooking up.
They wanted an industrial-strength blindfold to make sure volunteers for their work wouldn't be able to see a thing. "We basically got the best blindfold you can get." Tadin tells Shots. "It's made of black plastic, and it should block all light."
Anthropologist Lynne Isbell was running through a glade in central Kenya in 1992 when something suddenly caused her to freeze in her tracks. "I stopped just in front of a cobra," she says. "It was raised with its hood spread out."
Isbell, who is at the University of California, Davis, says she has spent the past couple of decades trying to understand how she could have reacted before her conscious brain even had a chance to think — cobra!
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.
