First glimpse of Higgs Bosons at work revealed

his 2011 image provide by CERN, shows a real CMS proton-proton collision in which 4 high energy electrons (green lines and red towers) are observed in a 2011 event. The event shows characteristics expected from the decay of a Higgs boson but is also consistent with background Standard Model physics processes.  To cheers and standing ovations, scientists at the world's biggest atom smasher claimed the discovery of a new subatomic particle Wednesday July 4, 2012, calling it "consistent" with the long-sought Higgs boson — popularly known as the "God particle" — that helps explain what gives all matter in the universe size and shape.

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.

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)

NASA Curiosity Rover is starting to explore dangerous new territory

The blue line added to this June 27, 2014, image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter is the edge of the ellipse that was charted as safe terrain for the rover's August 2012 landing. Curiosity is visible right on the ellipse line in the lower center of the image. This 3-sigma landing ellipse is about 4 miles long and 12 miles wide (7 kilometers by 20 kilometers). Curiosity reached the edge of it for the first time with a drive of about 269 feet (82 meters) earlier that day. (Credit: NASA)

Novel Technique to Measure Quantum-Optical Effect in Light from the Sun

Researchers detect tiniest of force ever measured

Mechanical oscillators translate an applied force into measureable mechanical motion. The Standard Quantum Limit is imposed by the Heisenberg uncertainty principle, in which the measurement itself perturbs the motion of the oscillator, a phenomenon known as “quantum back-action.” (Credit: Kevin Gutowski)

How the Aged Vacuum Tube Could Save Moore’s Law

One of the bulbs Thomas Alva Edison used to discover thermionic emission (the Edison Effect) in 1884. Edison found when he connected an ammeter between the filament and the auxiliary electrode, a current would flow, passing through the evacuated space of the bulb from filament to electrode. This current was later found to consist of electrons.
