In this artist's representation, an electron travels between two lasers in an experiment. The electron is spinning about its axis as a cloud of other subatomic particles are constantly emitted and reabsorbed. Some theories in particle physics predict particles, as yet undetected, that would cause the cloud to appear very slightly pear shaped when seen from a distance. With the support of the National Science Foundation, ACME researchers created an experiment setup look at that shape with extreme precision. To the limits of their experiment, they saw a perfectly round sphere, implying that certain types of new particles, if they exist at all, have properties different from those theorists expected. read more
The Laser Interferometer Space Antenna (LISA) will enable astrophysicists to observe gravitational waves emitted by black holes as they collide with or capture other black holes. LISA will consist of three spacecraft orbiting the sun in a constant triangle formation. Gravitational waves passing through will distort the sides of the triangle slightly, and these minimal distortions can be detected by laser beams connecting the spacecraft. LISA could therefore add a new sense to scientists' perception of the universe and enable them to study phenomena invisible in different light spectra. read more

A half century ago the infamous and timeworn trope coming from the supporters of the Viet Nam War was all over the airwaves. "Love It or Leave It" was the standard retort from the gung-ho believers to the anti-war activists, who filled the streets with civil disobedience. An entire era of youth came under suspicion, from fathers of that "Greatest Generation" for questioning the purpose and wisdom of American leaders and the military policy that drafted dissenting objectors into coercive service. read more
The Army adopted its battle rifle in 1963 and has spent 55 years looking for a replacement for the M-16 and its variants. They might have found it in Martin Grier's Colorado Springs garage. Grier, a self-described inventor who has worked at a local bed and breakfast, built the new "ribbon gun" with a hobbyist's tools. It looks like a space-age toy drawn by a fifth-grader.
