Subra Suresh has spent the last two decades studying the mechanical properties of engineered materials from the atomic to the structural scale. So, until recently, the head of MITs Department of Materials Science and Engineering never thought hed be a player in the hunt for cures to malaria and pancreatic cancer.
It turns out, however, that Sureshs expertise in nanotechnology is quite applicable to biology and medicine. With colleagues in engineering, science and medicine at MIT, the National University of Singapore (NUS) and the universities of Heidelberg and Ulm in Germany, he has adapted state-of-the-art tools for the study of the mechanical properties of materials to the study of living cells.
Now, in the January 2005 issue of Acta Biomaterialia, the researchers report the most complete and quantitative characterization yet of how a healthy human blood cell changes its shape, or deforms, upon being invaded by the malaria-inducing parasite Plasmodium falciparum. In the same article, the researchers show how the deformation of human pancreatic cancer cells in response to certain naturally occurring biomolecules may affect the metastasis of that disease. Ultimately, the work could lead to better treatments for these and other diseases.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
