Twisted light from ancient stars may have played a role in locking in aspects of the structure of life on Earth, and new findings from the University of Michigan provide insights into how that process may have occurred.

Testing for ovarian cancer or the presence of a particular chemical could be almost as simple as distinguishing an F sharp from a B flat, thanks to a new microscopic acoustic device that has been dramatically improved by scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory.

The seemingly simple process of phase changes—those transitions between states of matter—is more complex than previously known, according to research based at Princeton University, Peking University and New York University.

With fears growing over chemical and biological weapons falling into the wrong hands, scientists are developing microrockets to fight back against these dangerous agents, should the need arise. In the American Chemical Society journal ACS Nano, they describe new spherical micromotors that rapidly neutralize chemical and biological agents and use water as fuel.

While studying the atmosphere on Saturn’s moon Titan, scientists discovered intriguing zones of organic molecules unexpectedly shifted away from its north and south poles. These misaligned features seem to defy conventional thinking about Titan’s windy atmosphere, which should quickly smear out such off-axis concentrations.
