A key question that remains in biology and biophysics is how three-dimensional tissue shapes emerge during animal development. Research teams from the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) in Dresden, Germany, the Excellence Cluster Physics of Life (PoL) at the TU Dresden, and the Center for Systems Biology Dresden (CSBD) have…
U.S. wildlife officials are embracing a contentious plan to deploy trained shooters into dense West Coast forests to kill almost a half-million barred owls in coming decades. Their goal is to help spotted owls, which are being crowded out by barred owls from the eastern U.S. Past efforts to save spotted owls focused on protecting…
The Perseids are back to dazzle the sky with bursts of light and color. The annual meteor shower, active since July, peaks before dawn Monday. It’s one of the brightest and most easily viewed showers of the year, producing “bright blue meteors — and lots of them,” said University of Warwick astronomer Don Pollacco. More…
Anna Cockrell went public about her depression years ago, yet her misfortune didn’t cease until the U.S. athlete won silver in the 400-meter hurdles at the Paris Olympics.

Warm summer nights and swift colorful streaks make this meteor shower a crowd favorite, but this year, observers may have to compete with light from the moon.

Most of us learned about butterfly metamorphosis as a kid—a wriggly caterpillar molts its skin to form a tough chrysalis and emerges as a beautiful butterfly. But how exactly do chrysalises stay anchored as the butterfly brews within? Most of us learned about butterfly metamorphosis as a kid—a wriggly caterpillar molts its skin to form a…
Researchers from the University of Cambridge and the British Antarctic Survey tracked fire activity over the past 150 years by measuring carbon monoxide trapped in Antarctic ice. This gas is released, along with smoke and particulates, by wildfires, cooking and communal fires. Researchers from the University of Cambridge and the British Antarctic Survey tracked fire activity…
