The astonishing beauty of galaxies visible from Earth has enchanted humanity ever since our ancestors first gazed into the twinkling night and wondrously beheld them. Some galaxies look like elegant whirling spirals or cosmic frisbees, while others look like elliptical blobs or lumpy irregular clumps smeared across the sky. The variety of galactic shapes prompts questions as old as astronomy: why do galaxies form these characteristic shapes? Can elliptical galaxies become spirals, or vice versa?
One of the rare and brief bursts of cosmic radio waves that have puzzled astronomers since they were first detected nearly 10 years ago has finally been tied to a source: an older dwarf galaxy more than 3 billion light years from Earth.
UC Berkeley scientists have discovered simple CRISPR systems similar to CRISPR-Cas9 — a gene-editing tool that has revolutionized biology — in previously unexplored bacteria that have eluded efforts to grow them in the laboratory.
Berkeley’s worldwide network of smartphone earthquake detectors has recorded nearly 400 earthquakes since the MyShake app was made available for download in February, with one of the most active areas of the world the fracking fields of Oklahoma.
Following Earth’s last ice age, which peaked 20,000 years ago, the Antarctic warmed between two and three times the average temperature increase worldwide, according to a new study by a team of American geophysicists.
