11:36 AM | Shapeshifting metal nanoparticles eating tracks in graphene
A widely discussed method for the patterning of graphene is the channelling of graphene by metal nanoparticles in oxidizing or reducing environments. Researchers have now performed in-situ transmission electron microscopy experiments of silver nanoparticles channeling on graphene and discover that the interactions in the one-dimensional particle-graphene contact line are sufficiently strong so as to dictate the three-dimensional shape of the nanoparticles.

4:00 AM | Quando due galassie collidono
Durante il periodo natalizio, sappiamo che le luci sono le protagoniste assolute che allietano le serate notturne. Ma anche nel cosmo, da qualche parte a circa 130 milioni di anni-luce dalla Terra nella direzione della costellazione del Cane Maggiore, possiamo assistere ad uno spettacolo simile: stiamo parlando di una coppia di galassie a spirale interagenti … Continue reading Quando due galassie collidono →

2:08 AM | Chandra Weighs Most Massive Galaxy Cluster in Distant Universe
A newly discovered galaxy cluster is the most massive one ever detected with an age of 800 million years or younger. Using data from NASA's Chandra X-ray Observatory, astronomers have accurately determined the mass and other properties of this cluster, as described in our latest press release. This is an important step in understanding how galaxy clusters, the largest structures in the Universe held together by gravity, have evolved over time. A composite image shows the distant and massive […]

7:38 PM | Instant-start computers possible with new breakthrough
If data could instead be encoded without current it would require much less energy, and make things like low-power, instant-on computing a ubiquitous reality. Researchers have made a breakthrough in that direction with a room-temperature magnetoelectric memory device. Equivalent to one computer bit, it exhibits the holy grail of next-generation nonvolatile memory: magnetic switchability, in two steps, with nothing but an electric field.
