In a nanotechnology two-for-one, researchers at the Johns Hopkins University Center of Cancer Nanotechnology Excellence have created a polymer nanoparticle that overcomes tumor resistance to the common anticancer agent doxorubicin and that protects the heart against drug-triggered damage, a therapy-ending side effect that limits doxorubicin's effectiveness. This novel nanoparticle incorporates both doxorubicin and curcumin, a major component of the bright yellow spice turmeric.

One of the challenges in treating cancer, whether using nanotechnology or not, is that tumors can often be inaccessible to the therapies designed to kill them. Mostafa El-Sayed, of the Georgia Institute of Technology, and his colleagues are attempting to overcome this obstacle by designing drug-loaded gold nanorods that attract the attention of tumor-associated immune cells known as macrophages.

Quantum computers promise to reach computation speeds far beyond that of today's computers. As they would use quantum effects, however, they would also be susceptible to external interferences. Information flow into and out of the system is a critical point. Researchers from KIT with partners from Grenoble and Strasbourg have now read out the quantum state of an atom directly by using electrodes.

Quantencomputer versprechen Rechengeschwindigkeiten, die weit jenseits der Geschwindigkeit heutiger Computer liegen. Da sie Quanteneffekte nutzen w�rden, sind sie aber auch anf�llig f�r St�rungen von au�en und der Informationsfluss in und aus dem System ist ein kritischer Punkt. Nun haben Forscher vom KIT mit Partnern aus Grenoble und Stra�burg den Quantenzustand eines Atoms mittels Elektroden direkt ausgelesen.
