Smart scaffolding aims to rebuild tissue from the inside: NIH funds tissue engineering project at Rice University to test peptide hydrogels, starting with teeth

Smart scaffolding that can guide cells, proteins and small-molecule drugs to make new tissue and repair damage inside the body is in the works at Rice University.

Storms, Ozone, Vegetation and More: NASA-NOAA Suomi NPP Satellite Returns First Year of Data

These two images are season-long composites of ocean chlorophyll concentrations derived from visible radiometric measurements made by the VIIRS instrument on Suomi NPP. The date ranges of the two composites are included in the individual images. These false-colored images make the data stand out. The purple and blue colors represent lower chlorophyll concentrations. The oranges and reds represent higher chlorophyll concentrations. These differences in color indicate areas with lesser or greater phytoplankton biomass.

Odd pair of aging stars sculpt spectacular shape of planetary nebula

Astronomers using ESO’s Very Large Telescope have discovered a pair of stars orbiting each other at the centre of one of the most remarkable examples of a planetary nebula. The new result confirms a long-debated theory about what controls the spectacular and symmetric appearance of the material flung out into space.

What if the nanoworld slides: A new study to better understand how friction works

A study published by Andrea Vanossi, Nicola Manini and Erio Tosatti - three SISSA researchers - in PNAS (Proceedings of the National Academy of Sciences) provides a new tool to better understand how sliding friction works in nanotribology, through colloidal crystals.

Production of Graphene-Based Nanocomposite to Adsorb Water Pollutants

Iranian researchers announced production of particles with smaller size but higher surface area, and consequently more number of active sites, to adsorb pollutants by synthesizing cerium oxide-titanium dioxide nanoparticles and obtaining cerium oxide-titanium dioxide nanocomposite.
