Fast magnetic writing of data

Magnetic data storage has long been considered too slow for use in the working memories of computers. Researchers at ETH have now investigated a technique by which magnetic data writing can be done considerably faster and using less energy.

Quantum Machine Learning

An international team of scientists presents a thorough review in Nature on quantum machine learning, its current status and future prospects. Language acquisition in young children is apparently connected with their ability to detect patterns.

Self-assembling nanoparticle arrays can switch between a mirror and a window

By finely tuning the distance between nanoparticles in a single layer, researchers have made a filter that can change between a mirror and a window. The development could help scientists create special materials whose optical properties can be changed in real time. These materials could then be used for applications from tuneable optical filters to miniature chemical sensors.

Brain Composer: “thinking” melodies onto a musical score

TU Graz researchers develop new brain-computer interface application which allows music to be composed by the power of thought. Under the title of “Brain Composer”, a group led by BCI expert Gernot Müller-Putz from TU Graz’s Institute of Neural Engineering shows that experiences of quite a different tone can be sounded from the keys of brain-computer interfaces.

Sorting Molecules with DNA Robots

A DNA nanorobot is programmed to pick up and sort molecules into predefined regions. Imagine a robot that could help you tidy your home: roving about, sorting stray socks into the laundry and dirty dishes into the dishwasher.

Keychain detector could catch food allergens before it’s too late

For kids and adults with food allergies, a restaurant outing can be a fraught experience. Even when care is taken, freshly prepared or packaged meals can accidentally become cross-contaminated with an offending food and trigger a reaction. Now researchers report in the journal ACS Nano the development of a new portable allergen-detection system — including a keychain analyzer — that could help prevent trips to the emergency room.

A direct path from methane to methanol

In a study published today in Science, researchers from Lehigh and Cardiff University have demonstrated a promising approach to using colloidal gold-palladium nanoparticles to directly oxidize methane to methanol with high selectivity in aqueous solution at mild temperatures.
