Saturn's hexagon atmospheric phenomenon
An unusual structure with a hexagonal shape surrounding Saturn's north pole was spotted on the planet for the first time thirty years ago. Nothing similar with such a regular geometry had ever been seen on ...
Cassini captures familiar forms on Titan's dunes
(Phys.org) —The moons of our Solar System are brimming with unusual landscapes. However, sometimes they look a little more familiar, as in this new radar image from the Cassini orbiter. The image shows ...
Credit card-sized device could analyze biopsy, help diagnose pancreatic cancer in minutes
(Phys.org) —Pancreatic cancer is a particularly devastating disease. At least 94 percent of patients will die within five years, and in 2013 it was ranked as one of the top 10 deadliest cancers.
Squeezing light into metals: Team controls conductivity with inkjet printer
Using an inexpensive inkjet printer, University of Utah electrical engineers produced microscopic structures that use light in metals to carry information. This new technique, which controls electrical conductivity ...
Flowing water on Mars appears likely but hard to prove
(Phys.org) —Martian experts have known since 2011 that mysterious, possibly water-related streaks appear and disappear on the planet's surface. Georgia Institute of Technology Ph.D. candidate Lujendra Ojha ...
Researchers lay out theory for metamaterials that act as an analog computer
