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.

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.
