The changing face of Titan
On Saturn’s hazy moon Titan, torrential downpours of methane punctuate centuries of drought on a landscape of sand dunes and badlands
A tangled tale of topological fluids
Whether a large polymer is linear, simply branched like a star, or multiply branched dramatically affects how it moves through a densely entangled polymer soup
Geoscience research for our energy future
Understanding the complex interactions between pressurized fluids and porous rock is a key prerequisite to the safe sequestration of carbon dioxide and radioactive waste
Entangled light beams from four-wave mixing carry spatial information
Not only do the beams display correlations in their quantum fluctuations, but so do different parts of them when examined separately.
Very low-frequency radio waves drain Earth’s inner radiation belt of satellite-killing electrons
A high-altitude nuclear explosion would swell the radiation belt and imperil the global positioning system and other satellites. VLF transmissions could forestall the damage.
X-ray outburst reveals a supernova before it explodes
Long predicted but never before seen, the x-ray harbinger let observers record the supernova’s early light in unprecedented detail.
