NASA's Hubble Spots Possible Water Plumes Erupting on Jupiter's Moon Europa
This composite image shows suspected plumes of water vapor erupting at the 7 o'clock position off the...
Gold nanoparticles conjugated quercetin inhibits epithelial-mesenchymal transition, angiogenesis and invasiveness via EGFR/VEGFR-2 mediated pathway in breast cancer
Cell viability was assessed by MTT assay, and protein expression was examined by Western blotting and immunocytochemistry. Cell invasion was monitored using invasion chambers, and cell migration was analysed by scratch wound-healing assay. In vitro...
Hubble: Possible Water Plumes on Jupiter's Moon Europa
Astronomers using NASA's Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor...
Scientists Find Twisting 3-D Raceway for Electrons in Nanoscale Crystal Slices
Researchers have created an exotic 3-D racetrack for electrons in ultrathin slices of a nanomaterial they fabricated at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).
Chains of nanogold – forged with atomic precision
Researchers at Nanoscience Center of University of Jyväskylä in Finland have succeeded in producing short chains and rings of gold nanoparticles with unprecedented precision. They used a special kind of nanoparticles with a well-defined structure and...

NEWS & PRESS Astronomers observe star reborn in a flash
Using the Hubble Space Telescope, an international team of astronomers has been able to study stellar evolution in real time. Over a period of 30 years dramatic increases in the temperature of the star SAO 244567 have been observed. Now the star is...
Starving Black Hole Returns Brilliant Galaxy to the Shadows
Many galaxies are found to have an extremely bright core powered by a supermassive black hole. These cores make “active galaxies” some of the brightest objects in the Universe. They are thought to shine so brightly because hot material is glowing...
