One more step on the path to quantum computers

Correo electrónico Imprimir PDF

Researchers around the world are working on the development of quantum computers that will be vastly superior to present-day computers. Here, the strong coupling of quantum bits with light quanta plays a pivotal role. Professor Rudolf Gross, a physicist at the Technische Universitaet Muenchen, and his team of researchers have now realized an extremely strong interaction between light and matter that may represent a first step in this direction.

Reading terrorists minds about imminent attack

Imagine technology that allows you to get inside the mind of a terrorist to know how, when and where the next attack will occur. That may not be as far-fetched as it sounds. Northwestern brain wave research suggests that if the lab test had been employed in the real world with the same type of outcome, law enforcement officials ultimately may be able to confirm details about an attack that emerges from terrorist chatter.

Effective inducing systems of hepatic differentiation from bone marrow mesenchymal stem cells

Correo electrónico Imprimir PDF

Mesenchymal stem cells (MSCs) are multipotent non-hematopoietic cells capable of differentiating into hepatocytes. Valproic acid (VPA), a histone deacetylase inhibitor, has recently exhibited profound therapeutic activity in preclinical tumor test. A research group in China investigated the induction of hepatic differentiation of mouse bone marrow MSCs (mBM-MSCs) by VPA. Direct evidences have been shown that the usefulness of VPA in the trans-differentiation of mBM-MSCs into hepatocytes both in vitro and in vivo.

Reforestation projects capture more carbon than industrial plantations, reveals new research

Correo electrónico Imprimir PDF

Australian scientists researching environmental restoration projects have found that the reforestation of damaged rainforests is more efficient at capturing carbon than controversial softwood monoculture plantations. The research, published in Ecological Management & Restoration, challenges traditional views on the efficiency of industrial monoculture plantations.
