Frog evolution tracks rise of Himalayas and rearrangement of Southeast Asia
The spiny frogs of Asia have hard, nubby spines on their chests and arms and Popeye-like forearms in order to securely grasp females during mating in swift-flowing streams. Kunming Institute of Zoology and UC Berkeley biologists have conducted a genetic analysis of 24 species of spiny frogs to track the rise of the Himalayas and the Tibetan Plateau that led to their diversification.
For the first time ever, scientists watch an atom’s electrons moving in real time
A team of German and UC Berkeley scientists, including physicist Stephen Leone, have used ultrashort flashes of laser light to directly observe for the first time the movement of an atom’s outer electrons. The technique could be valuable in the study of photosynthesis.
Genome of ancient sponge reveals origins of first animals, cancer
A team led by Daniel Rokhsar has published a draft genome sequence of the sea sponge, an organism that wasn't recognizied as an animal until the 19th century. The genome gives insight into the origins of multicellular animals and cancer.
