Space-traveling flatworms help scientists enhance understanding of regenerative health

more »
Flatworms that spent five weeks aboard the International Space Station are helping researchers scientists study how an absence of normal gravity and geomagnetic fields can have anatomical, behavioral, and bacteriological consequences, according to a paper. The research has implications for human and animal space travelers and for regenerative and bioengineering science.

New confirmation of Einstein's General Theory of Relativity

more »
Albert Einstein predicted that whenever light from a distant star passes by a closer object, gravity acts as a kind of magnifying lens, brightening and bending distant starlight. Yet, Einstein added, 'There is no hope of observing this phenomenon directly.' Now, researchers have done just that, saying that the discovery opens a new window to understanding 'the history and evolution of galaxies such as our own.'

M27: Not a Comet

more »
While hunting for comets in the skies above 18th century France, astronomer Charles Messier diligently kept a list of the things he encountered that were definitely not comets. This is number 27 on his now famous not-a-comet list. In fact, 21st century astronomers would identify it as a planetary nebula, but it's not a planet either, even though it may appear round and planet-like in a small telescope. Messier 27 (M27) is an excellent example of a gaseous emission nebula created as a sun-like star runs out of nuclear fuel in its core. The nebula forms as the star's outer layers are expelled into space, with a visible glow generated by atoms excited by the dying star's intense but invisible ultraviolet light. Known by the popular name of the Dumbbell Nebula, the beautifully symmetric interstellar gas cloud is over 2.5 light-years across and about 1,200 light-years away in the constellation Vulpecula. This spectacular color image incorporates broad and narrowband observations recorded by the 8.2 meter Subaru telescope.

Quantum nanoscope: Seeing electrons surfing the waves of light on graphene

more »
Researchers have studied how light can be used to 'see' the quantum nature of an electronic material. They managed to do that by capturing light in a net of carbon atoms and slowing down light it down so that it moves almost as slow as the electrons in the graphene.
