Microbubbles are specially-coated bubbles which are designed primarily to enhance ultrasound pulse-echo imaging. Their use significantly enhances sound echoes, thereby improving detection accu- racy, and therefore diagnosis, of ‚difficult‘ cancers (such as liver and prostate), and breast cancers.
Microbubbles (and specially designed ultrasonic fields) are also being studied worldwide as possible vehicles for drug and gene delivery. They promise to play a crucial role in fighting Alzheimer‘s disease, or cancers in which the use of chemotherapy is deemed too risky to the patient, and thus a targeted therapy is more effective.
CEA-Leti and the Laboratory of Microelectronics Technologies (LTM) have signed a four-year part- nership agreement to focus on the development of new technologies in nanoelectronics.
spin quantum-jumps with a single trapped proton for the first time. The fact that they have managed to procure this elu- sive data means that they have overtaken their research com- petitors at Harvard University and are now the global lea- ders in this field. The result is a pionee- ring step forward in the endeavor to directly measure the magnetic properties of the proton with high precision. The measuring principle is based on the ob- servation of a single proton stored in an electromagnetic par- ticle trap.

Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM), together with their colleagues from the Max Planck Institute for Nuclear Physics in Heidel- berg and the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, Germany, have observed
As it would also be possible to observe an anti- proton using the same method, the prospect that an explanation for the matter-antimatter imbalance in the universe could be found has become a reality. It is essential to be able to analyze antimatter in detail
