Rosetta measures comet's temperature
(Phys.org) —ESA's Rosetta spacecraft has made its first temperature measurements of its target comet, finding that it is too hot to be covered in ice and must instead have a dark, dusty crust.
Experiments show disproportionately large number of big boulders on asteroids likely due to Brazil-nut effect
Researchers find evidence of super-fast deep earthquake
As scientists learn more about earthquakes that rupture at fault zones near the planet's surface—and the mechanisms that trigger them—an even more intriguing earthquake mystery lies deeper in the planet.
Hot tropical oceans during Pliocene greenhouse warming
The impact of the greenhouse gas CO2 on the Earth's temperature is well established by climate models and temperature records over the past 100 years, as well as coupled records of carbon dioxide concentration ...
Morphable surfaces could cut air resistance
There is a story about how the modern golf ball, with its dimpled surface, came to be: In the mid-1800s, it is said, new golf balls were smooth, but became dimpled over time as impacts left permanent dents. ...
New evidence for oceans of water deep in the Earth
Researchers from Northwestern University and the University of New Mexico report evidence for potentially oceans worth of water deep beneath the United States. Though not in the familiar liquid form—the ...
Warming climates intensify greenhouse gas given out by oceans
Rising global temperatures could increase the amount of carbon dioxide naturally released by the world's oceans, fuelling further climate change, a study suggests.
Opening a wide window on the nano-world of surface catalysis
(Phys.org) —Surface catalysts are notoriously difficult to study mechanistically, but scientists at the University of South Carolina and Rice University have shown how to get real-time reaction information ...
Just add water: 3-D silicon shapes fold themselves when wetted by microscopic droplets
Researchers from the University of Twente in the Netherlands have taken the precise art of origami down to the microscopic scale. Using only a drop of water, the scientists have folded flat sheets of silicon ...
Unexpected water explains surface chemistry of nanocrystals
Danylo Zherebetskyy and his colleagues at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) found unexpected traces of water in semiconducting nanocrystals.
Soap films with complex shapes shed light on the formation of mathematical singularities (w/ Video)
(Phys.org) —Soap films with complex shapes shed light on the formation of mathematical singularities, which occur in a broad range of fields.
Physics team develops simple way of controlling surface plasmon polaritons in graphene
New super waterproof surfaces cause water to bounce like a ball
(Phys.org) —In a basement lab on BYU's campus, mechanical engineering professor Julie Crockett analyzes water as it bounces like a ball and rolls down a ramp.
