Over 1,000 aspirants, including 62 from India, have been shortlisted for an ambitious private mission to send four men and women on a one-way trip to Mars in 2024 to establish a More »
Thanks to the work of an interdisciplinary team of researchers at the Dartmouth Center of Nanotechnology Excellence, funded by the National Institutes of Health, the next-generation magnetic nanoparticles (MNPs) may soon be treating deep-seated and difficult-to-reach tumors within the human body. Though the researchers caution that any new therapies based on their discoveries will have to prove safe and effective in clinical trials before becoming routinely available for people with cancer, they point to the work they published this week in the Journal of Applied Physics, from AIP Publishing, as significant progress.
Pietro Valdastri is convinced that the clever application of magnetic force can make minimally invasive surgery easier and more effective. “In 2007, a team of University of Texas researchers did some basic experiments using magnets in laparoscopic surgery,” said Valdastri, assistant professor of mechanical engineering and director of Vanderbilt University’s Science and Technology of Robotics in Medicine (STORM) Lab.
“Although their designs were very simple, mechanically speaking, they made me realize that small surgical devices guided and powered by external magnets have a number of potential advantages over placing tools on the end of a stick, which is the current approach. All that was required is a little sophisticated engineering!”
The team responsible for the Oscar-nominated visual effects at the centre of Christopher Nolan’s epic, Interstellar, have turned science fiction into science fact by providing new insights into the powerful effects of black holes. In a paper published today, 13 February, in IOP Publishing’s journal Classical and Quantum Gravity, the team describe the innovative computer code that was used to generate the movie’s iconic images of the wormhole, black hole and various celestial objects, and explain how the code has led them to new science discoveries.
