Scientists at MU, Oak Ridge National Laboratory and the University of Tennessee at Knoxville created a gold nanoparticle that can transport powerful radioactive particles directly to tumors for treatment.

We’ve all heard that “it’s not wise to use a cannon to kill a mosquito.” But what if you could focus the cannon’s power to concentrate power into a tiny space? In a new study, University of Missouri researchers have demonstrated the ability to harness powerful radioactive particles and direct them toward small cancer tumors while doing negligible damage to healthy organs and tissues. The study is being published this week in PLOS ONE, an international, peer-reviewed and open-access publication. (more…)

Don’t believe in Santa Claus? Magic, you say? In fact, science and technology explain how Santa is able to deliver toys to good girls and boys around the world in one night, according to a North Carolina State University researcher.

NC State’s Dr. Larry Silverberg, professor of mechanical and aerospace engineering, can explain the science and engineering principles that allow Santa, also known as Kris Kringle or Saint Nicholas, to pull off the magical feat year after year. (more…)

*Specialized structures used by cancer cells to invade tissues could also help them escape protection mechanisms aimed at eliminating them, a UA-led research team has discovered.*

Delicate, threadlike protrusions used by cancer cells when they invade other tissues in the body could also help them escape control mechanisms supposed to eliminate them, a research group led by led by Bradley Davidson in the University of Arizona’s department of molecular and cellular biology reports in Nature Cell Biology.

Studying embryos of the sea squirt Ciona intestinalis, the researchers discovered that even non-invasive cells make the delicate, highly transient structures known as invadopodia. The group found that future heart cells in the Ciona embryo use invadopodia to pick up chemical signals from their surroundings. These so-called growth factors provide the cells with clues as to where they are in the developing embryo and what type of cell they are supposed to turn into. (more…)
