The machine learning community contest to take on the Higgs

(Credit: Sandbox Studio, Chicago) — Kaggle is currently running about 20 contests on its site. Most of them will attract between 300 and 500 teams. But the Higgs contest, which does not end until September, has already drawn almost 970. Names appear and drop off of the leader board every day. (Credit: Sandbox Studio, Chicago)

Physicists propose molecular clock to expose new physics

(Credit: S. Schiller et al., Phys. Rev. Lett (2014)) — A lot of physics is based on the assumption that the mass of a proton remains constant over time—pretty much forever. But what if that’s not true? What if it grows or shrinks over time? That would mean that the ratio between them and electrons changes as well, and if that’s true, then physicists are going to have to come up with some new ideas to explain what that might mean.

Huge Meteorite on Mars Discovered by NASA’s Curiosity Rover

This photo by NASA's Curiosity Mars rover shows the huge iron meteorite "Lebanon" (7 feet wide) and its smaller companion "Lebanon B." The two meteorites were found by Curiosity on May 25, 2014. The circular insets are more detailed views by Curiosity's Chem-Cam instrument overlaid on an image by the rover's Remote Micro-Imager.

Cassini spacecraft’s new look at Saturn’s colossal hexagon storm

(Credit: NASA/JPL-Caltech/SSI) — The clear central eye of the storm is about 2000 km across – ten times the typical size on Earth – and clouds at the outer edge of the hurricane on Saturn are moving at more than 500 kph – rather faster than on Earth. (Credit: NASA/JPL-Caltech/SSI)

Large number of dark matter peaks found using gravitational lensing

This map shows the distribution of dark matter (black) in the Universe, overlapping with optical measured clusters of galaxies (red circles). The mass peaks in the map contain significant cosmological information, will provide us with an improved understanding about the dark side of the Universe. The size of this map is about 4 square degrees corresponding to only 2.5% of the full CS82 survey footprint shown in the next figure. (Credit: CS82, SDSS)
