The type of eruptions are known as fissure eruptions, in which there are normally no large explosions or significant spreading of ash. Nevertheless, the bright red-orange glow of the eruptions could also be seen from the capital Reykjavik, which lies around 55 kilometres north-east of Grindavík. Although the lava has slowed, Einar Hjörleifsso...

Whale of a tail: Scientists track unique humpback 'fingerprint'

In Antarctica, a scientist waits patiently for two frolicking humpback whales to poke their tails out of the icy waters so she can take a photographic "fingerprint" of the unique colors and patterns that allow researchers to identify individuals of the species.

Proteins in milk and blood could one day let doctors detect breast cancer earlier

Doctors may someday be able to use bodily fluids to noninvasively detect breast cancer in patients earlier than is possible now.

Breast cancer is the most commonly diagnosed cancer among women in the U.S. and is currently one of the leading causes of cancer deaths. Earlier diagnosis and treatment lead to better prognoses for breast cancer patients. But mammograms have proved to be less effective for those under age 40, as their breast tissue is denser and screening and biopsies can be unpleasant to endure.
