Just imagine, a stress-free, relaxing amble through a leafy glade, the sound of water gently gushing by. The sunlight filters through the green canopy to dapple the banks of the soothing river.

Surprising qualities of insulator ring surfaces
more »
Topological insulators behave like insulators at their core and allow good conductivity on their surface. They owe their characteristics to a new quantum state within the material discovered in 2007 and 2009 for 2-D and 3-D materials, respectively. Scientists studying the surface of ring-shaped, or toric, topological insulators, have just discovered some characteristics that had only previously been confirmed in spheres.

German Astronomical Society (AG) Awards Robert Williams the Karl Schwarzschild Medal
Get larger image formats
The German Astronomical Society (AG) has announced that the most prestigious prize in Germany in the field of astronomy and astrophysics, the Karl Schwarzschild Medal, will be awarded this year to Robert Williams of the Space Telescope Science Institute (STScI) in Baltimore, Maryland. In Robert Williams the AG honors not only an outstanding scientist, but also a man with a dedication to scientific training and astronomical outreach. His name is inseparably linked to the most celebrated observation target of the Hubble Space Telescope (HST): the famous Hubble Deep Field (HDF). The German Astronomical Society will award the Karl Schwarzschild Medal, whose previous recipients include five Nobel laureates, to Robert Williams on September 13, 2016, during the opening ceremony of the annual conference of the AG in Bochum, Germany. The award is named after the German physicist and astronomer Karl Schwarzschild (1863-1916), one of the pioneers of modern astrophysics.

How planetary age reveals water content
more »
Water is necessary for life as we know it, but too much water is bad for habitability. Therefore, to study the habitability of extrasolar planets, determining the abundance of water is a key element. Astronomers now show that the observation of exoplanets at different ages can be used to set statistical constraints on their water content -- an important result for future space missions.

Tracking solar eruptions in 3D
more »
Scientists have developed an automated method for three-dimensional tracking of massive eruptions from the Sun, called Coronal Mass Ejections (CMEs). The Automated CME Triangulation (ACT) system uses data from three space-based observatories that orbit the Sun at different locations, allowing scientists to view the Sun and CMEs from different angles. ACT's ability to track whether a CME is heading towards Earth, and when it is likely to reach us, should lead to significant improvements in space weather forecasting.

From Alpha to Omega in Crete
more »
This beautiful telephoto composition spans light-years in a natural night skyscape from the island of Crete. Looking south, exposures both track the stars and record a fixed foreground in three merged panels that cover a 10x12 degree wide field of view. The May 15 waxing gibbous moonlight illuminates the church and mountainous terrain. A mere 18 thousand light-years away, huge globular star cluster Omega Centauri (NGC 5139) shining above gives a good visual impression of its appearance in binoculars on that starry night. Active galaxy Centaurus A (NGC 5128) is near the top of the frame, some 11 million light-years distant. Also found toward the expansive southern constellation Centaurus and about the size of our own Milky Way is edge on spiral galaxy NGC 4945. About 13 million light-years distant it's only a little farther along, and just above the horizon at the right. Tomorrow's picture: the artificial night

Graphene oxide and rGO microparticles not toxic to mouse lung cells
more »
via Graphenea
Recent research showed that graphene (reduced graphene oxide, rGO) and graphene oxide (GO) particles larger than 1 micron in size are not cytotoxic or genotoxic to mouse lung cells. The study, performed using Graphenea graphene and involving the company's scientists, tested GO and rGO toxicity epithelial FE1 cells in vitro. GO and rGO have potential uses in biomedical applications, for example in biosensors, as a substrate in mass spectroscopy and for cell growth, and as drug delivery carriers.
Toxicity of nanoparticles (NP) is an important topic, due to the growing prevalence of NPs in research and production. Because of the multitude of compositions, shapes, and sizes of NPs, toxicity is an issue that needs to be addressed to each type of NP separately.
Figure: Morphology of GO and rGO (Wiley).
The first step in toxicity research always takes place “in vitro”, where cells are exposed to the potentially harmful agent and later analyzed for damage. The latest research, involving eight institutions from Denmark, France, and Spain, concluded that few layered GO and rGO with lateral size above 1 micrometer were not cytotoxic or genotoxic to FE1 mouse epithelial cells at concentrations up to 200 micrograms/ml. Mouse lung cells are commonly used in the first steps of toxicity studies. Although our study shows that no DNA strand breaks occur in cells due to exposure to GO and rGO particles of this size, earlier studies reveal that smaller particles, i.e. GO nanoparticles with sizes smaller than 500 nm, do cause DNA strand breaks. Carbon black has also been shown to be toxic and possibly carcinogenic to humans.
The research was published in the journal Environmental and Molecular Mutagenesis.
