Nanotechnology offers powerful new possibilities for targeted cancer therapies, but the design challenges are many. Northwestern University scientists now are the first to develop a simple but specialized nanoparticle that can deliver a drug directly to a cancer cell's nucleus -- an important featur...
Scientists have overcome a major hurdle facing quantum computing: how to protect quantum information from degradation by the environment while simultaneously performing computation in a solid-state quantum system. The research was reported in the April 5 issue of Nature.
A Martian dust devil roughly 12 miles high (20 kilometers) was captured whirling its way along the Amazonis Planitia region of Northern Mars on March 14. It was imaged by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. Despite its height, the plu...
Scientists from Duke University Medical Center have determined that genes acting as molecular "on/off" switches can define clinically relevant molecular subtypes of ovarian cancer, providing ideal potential targets for use in clinical prognostic and diagnostic testing. These bimodal genes can define...
Through the course of her career, Barbara Romanowicz has studied the Earth from its surface to its center, establishing herself as one of the most influential seismologists of her time. For her outstanding contributions in seismology and earthquake engineering, the Seismological Society of America (...
The vantage point from orbit on the International Space Station (ISS) frequently affords astronauts with the opportunity to observe processes that are impossible to see on the ground. The winter season blankets the Kamchatka Peninsula of Russia in snow, but significant amounts of sea ice can also fo...
Researchers at Harvard University have developed a robotic device made from DNA that potentially could seek out specific cell targets within a complex mixture of cell types and deliver important molecular instructions, such as telling cancer cells to self-destruct. Inspired by the mechanics of the b...
One day in the fall of 2011, Neil Sheeley, a solar scientist at the Naval Research Laboratory in Washington, D.C., did what he always does - look through the daily images of the sun from NASA's Solar Dynamics Observatory (SDO).
A North Carolina State University researcher has developed a more efficient, less expensive way of cooling electronic devices - particularly devices that generate a lot of heat, such as lasers and power devices.
The color and scent of flowers and their perception by pollinator insects are believed to have evolved in the course of mutual adaptation. However, an evolutionary biologist from the University of Zurich has now proved that this is not the case with the arum family at least, which evolved its scent ...
Bacteria are the most populous organisms on the planet. They thrive in almost every known environment, adapting to different habitats by means of genetic variations that provide the capabilities essential for survival. These genetic innovations arise from what scientists believe is a random mutation...
It may seem like a game of tag, but it's an innovative tool for teaching the fundamentals of epidemiology, the science of how infectious diseases move through a population.
