Cancer vaccines have recently emerged as a promising approach for killing tumor cells before they spread. But so far, most clinical candidates haven't worked that well. Now, scientists have developed a new way to deliver vaccines that successfully stifled tumor growth when tested in laboratory mice. And the key is in the vaccine's unique stealthy nanoparticles.
Using mesocosms that closely approximate wetland ecosystems, researchers show carbon nanotubes accumulate quickly in sediments - a tendency that could indirectly damage aquatic food chains by piggybacking harmful molecules.
Thermal considerations are rapidly becoming one of the most serious design constraints in microelectronics, especially on submicron scale lengths. A new study has shown that standard thermal models will lead to the wrong answer in a three-dimensional heat-transfer problem if the dimensions of the heating element are on the order of one micron or smaller.
Having the possibility to measure magnetic properties of materials at atomic precision is one of the important goals of today's experimental physics. Researchers propose a new method, utilizing properties of the quantum world - the phase of the electron beam - to detect magnetism with atom-by-atom precision.
Researchers can now for the first time remotely control a miniature light source at timescales of 200 trillionth of a second. They have developed a way of remotely controlling the nanoscale light sources at an extremely short timescale. These light sources are needed to be able to transmit quantum information.
Using a bio-mimicking analog of one of nature's most efficient light-harvesting structures, blades of grass, a research team has taken a major step in developing long-sought polymer architecture to boost power-conversion efficiency of light to electricityA breakthrough in morphology control should have widespread use in solar cells, batteries and vertical transistors.
Heart tissue is unable to repair itself after a heart attack because heart cells cannot multiply and cardiac muscles contain few stem cells. Now, researchers are literally setting a new gold standard in cardiac tissue engineering.
Scientists have designed a first-ever experiment for demonstrating quantum entanglement in the macroscopic realm. Unlike other such proposals, the experiment is relatively easy to set up and run with existing semiconductor devices.
Electrical engineers have demonstrated a new kind of building block for digital integrated circuits. Their experiments show that future computer chips could be based on three-dimensional arrangements of nanometer-scale magnets instead of transistors.
