The price tag of DNA sequencing has been dropping steadily since researchers completed sequencing the first human genome in 2003 at a cost of about $3 billion. Today, new sequencing technologies have brought the figure close to $1000 per genome, although precise costs are hard to come by.
Like actors in a scene from a bawdy farce, many squid don't know whom to woo when the lights go down. Deep in California's Monterey Bay, small squid belonging to the species Octopoteuthis deletron suffer from frequent cases of mistaken identity, a new study suggests.
Fluffy structures trapped in thumbnail-sized bits of ancient amber may represent some of the earliest evolutionary experiments leading to feathers, according to a new study. These filaments of "dinofuzz" are so well preserved that they even provide hints of color, the researchers say.
If you’ve ever been too full to move after a large meal, envy the leech. That darling of medieval physicians and terror of river bathers can gorge as much as it wants and still squirm away, even if it bloats up to 10 times its normal size.
Researchers have developed a new way to create true-color holograms that can be viewed from any angle using ordinary white light. The advance could lead to a new generation of electronic devices, such as cell phones or miniature televisions that display three-dimensional (3D) images.
Many plant-eating sauropod dinosaurs sported very long necks—though researchers have debated their purpose. Now, using some fancy mathematics and an analogy with vacuum cleaners, two scientists in the United Kingdom may finally have the answer.
It turns out that worms really are deeply divided. In the mid-19th century, French naturalist Armand de Quatrefages split worms into wigglers—which crawl and swim to their hearts' content, such as the marine ragworm— and the more sedentary, typically tube-dwelling nonwigglers, such as the earthworm.
A predator that can't hunt won't last very long. So when biologists found a carnivorous plant in Borneo that was bad at catching insects, they were puzzled. Just what does it eat to stay alive? The answer, a new study reveals, appears to be bat guano.
