Researchers have discovered that a molecule best known for its anti-microbial properties also has the ability to activate key cells in the immune response. This newly discovered function, reported in the Nov. 1, 2002, issue of Science*, suggests the molecule, a peptide called ß-defensin 2, may be useful in the development of more effective cancer vaccines. Scientists have found that ß-defensin 2 initiates a chain of events leading to the growth and multiplication of T cells, components of the immune system that recognize and kill foreign cells that have invaded the body.
Defensins are known to be an important component of the bodys immediate response to infection. ß-defensin 2 attacks and destroys a broad range of bacteria as part of the innate immune system, the bodys first line of defense against such infections.
The new finding links ß-defensin 2 to the second arm of the immune system, adaptive immunity. The adaptive immune response combats pathogens that evade the bodys initial defense mechanisms. Unlike innate immunity, the adaptive immune system develops specifically in response to an infection, changing as needed to ward off each invader.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
