Snow in an Infant Planetary System
A snow line has been imaged in a far-off infant planetary system for the very first time. The snow line, located in the disc around the Sun-like star TW Hydrae, promises to tell us more about the formation of planets and comets, the factors that decide their composition, and the history of the Solar System.

CERN experiments put Standard Model to stringent test – UK reaction here
New results being presented at the EPS-HEP conference in Stockholm, Sweden, this afternoon (19th July 2013) have put the Standard Model of particle physics to one of its most stringent tests to date. The CMS and LHCb experiments at CERN’s Large Hadron Collider will present measurements of one of the rarest measureable processes in physics: the decay of a Bs (pronounced B-sub-s) particle into two muons.

New nanoscale imaging method finds application in plasmonics
Infrared laser light (purple) from below a sample (blue) excites ring-shaped nanoscale plasmonic resonator structures (gold). Hot spots (white) form in the rings' gaps. In these hot spots, infrared absorption is enhanced, allowing for more sensitive chemical recognition. A scanning AFM tip detects the expansion of the underlying material in response to absorption of infrared light.

Disks Don't Need Planets to Make Patterns
Debris disks around stars naturally form complex structures without the presence of a planet. This image shows the dust density and the growth of structure in a simulated disk, which extends about 100 times farther from its star than Earth's orbit around the sun. At left, the disk is seen from a 24-degree angle; at right, it's face-on. Lighter colors show greater dust concentrations.

Smart anticancer nanofibers: Setting treatments to work together
Design concept for a smart hyperthermia nanofiber system that uses magnetic nanoparticles (MNPs) dispersed in temperature-responsive polymers. Anticancer drug, doxorubicin (DOX), is also incorporated into the nanofibers. The nanofibers are chemically crosslinked. First, the device signal (alternating magnetic field, AMF) is turned 'on' to activate the MNPs in the nanofibers. Then, the MNPs generate heat to collapse the polymer networks in the nanofiber, allowing the 'on-off' release of DOX. Both the generated heat and released DOX induce apoptosis of cancer cells by hyperthermic and chemotherapeutic effects, respectively.
