A remote control for neurons

A team led by researchers at Carnegie Mellon University has created a new technology that enhances scientists' ability to communicate with neural cells using light. Tzahi Cohen-Karni, associate professor of biomedical engineering ...

Extending nucleic acid memory (NAM)

Humanity is creating huge amounts of data every day, billions of emails and social media updates, new websites, documents, images, and scientific and commercial big data amounting to petabytes of storage needs and beyond. ...

Extraction of skin interstitial fluid using microneedle patches

Interstitial fluid is a major component of the liquid environment in the body and fills the spaces between the body's cells. In contrast, blood circulates only within the circulatory vessels of the body and is composed of ...

Van der Waals junction spin valves without spacer layer

The fundamental principle of a spin valve is that the resistance is dependent on the parallel or antiparallel configurations of the two ferromagnetic electrodes, thus associating the magnetoresistance (MR) effect, whose basic ...

Study finds electrical fields can throw a curveball

MIT researchers have discovered a phenomenon that could be harnessed to control the movement of tiny particles floating in suspension. This approach, which requires simply applying an external electric field, may ultimately ...

Topological insulators feature lossless conduction at the edges

Atomically thin layers of the semimetal tungsten ditelluride conduct electricity losslessly along narrow, one-dimensional channels at the crystal edges. The material is therefore a second-order topological insulator. By obtaining ...

New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick ...

Watching single protons moving at water-solid interfaces

The H+ proton consists of a single ion of hydrogen, the smallest and lightest of all the chemical elements. These protons occur naturally in water where a tiny proportion of H2O molecules separate spontaneously. Their amount ...

Cockle shells picked to treat dog cancer

The calcium mineral from which many shellfish, such as cockles, make their shells can be used to form nanoparticles. These nanoparticles can then be "loaded" with small drug molecules, such as anticancer drugs.
