Curative Multicycle Radioimmunotherapy Monitored by Quantitative SPECT/CT-Based Theranostics, Using Bispecific Antibody Pretargeting Strategy in Colorectal Cancer. Journal of Nuclear Medicine, 2017; 58 (11): 1735 DOI: 10.2967/jnumed.117.193250

Novel 3-step pretargeted radioimmunotherapy offers safe, effective treatment. In this study with a mouse model, researchers achieved a 100% cure rate -without any treatment-related toxic effects. Until now, radioimmunotherapy (targeted therapy) of solid tumors using antibody-targeted radionuclides has had limited therapeutic success. “This research is novel because of the benchmarks reached by the treatment regimen, in terms of curative tumor doses, with non-toxic secondary radiation to the body’s normal tissues,” explains Steven M...

Dendritic fibrous nanosilica (DFNS), also known as KCC-1, has a unique fibrous morphology and a high surface area with improved accessibility to the internal surface, tunable pore size and volume, controllable particle size, which made it useful in the fields of energy, environment, and health.

Dendritic fibrous nanosilica (DFNS) attracted a great deal of attention in a large number of scientific disciplines such as catalysis, solar energy harvesting (photocatalysis, solar cells, etc...

The comet entered the bottom of STEREO’s view and crossed it diagonally before leaving on Oct. 28. Most of the corona has been suppressed in order to bring out the comet, leaving only the dynamic flow of the solar wind. Credit: NASA’s Goddard Space Flight Center/STEREO/Bill Thompson/Joy Ng

ESA and NASA mission SOHO – Solar and Heliospheric Observatory – got a visit from an old friend this week when comet 96P entered its field of view on Oct. 25, 2017. The comet entered the lower right corner of SOHO’s view, and skirted up and around the right edge before leaving on Oct. 30. SOHO also spotted comet 96P in 1996, 2002, 2007 and 2012, making it the spacecraft’s most frequent cometary visitor.

At the same time, comet 96P passed through a second NASA mission’s view: STEREO – Solar and Terrestria...

When NASA’s Mars Pathfinder touched down in 1997, it had five cameras: 2 on a mast that popped up from the lander, and three on NASA’s first rover, Sojourner. Since then, camera technology has taken a quantum leap. Photo sensors that were improved by the space program have become commercially ubiquitous. Cameras have shrunk in size, increased in quality and are now carried in every cellphone and laptop.

That same evolution has returned to space...
