Galileo merged the fields of cosmology and astronomy, thanks to his telescope, which gave scientists a more accurate way to observe and define the heavens. His telescope helped shift authority in the…

Galileo's contributions to science in general, and optics and astronomy in particular, were so monumental that over 350 years later we still discuss them in introductory physics courses. A recent…

Galileo Galilei wasn't just an Italian physicist, mathematician, astronomer, philosopher and heresy suspect (not to mention father of modern observational astronomy, modern physics, science, and…

A real life Alice In Wonderland story is a little closer to reality now that researchers in China have created the first tunable electromagnetic gateway. In a new paper,  researchers from the…

Superman's X-ray vision may be closer than you think.   The tubes that power X-ray machines are shrinking and also improving in clarity. A team of nanomaterial scientists, medical physicists,…

Albert Einstein's theory of general relativity, which describes how the gravity of a massive object like a star can curve space and time, has been successfully used to predict the bending of…

There's a bipolar force with a repulsive side that doesn't involve cosmic opera or wooden acting - it's light.  And it can be used to control components on silicon microchips, meaning future…

A team of physicists and engineers have demonstrated all-fibre quantum logic, where single photons are generated and used to perform the contolled-NOT quantum logic gate in optical fibers with high…

Ounce for ounce, spinach has more nutritional value than iceberg lettuce; in general, darker colors in leafy vegetables mean more antioxidants and therefore more health benefits. Knowing that, plant…

Tunable fluidic micro lenses can focus and direct light at will to count cells, evaluate molecules or create on-chip optical tweezers, according to a team of Penn State engineers. They may also…
