Nanoscale wrench is just 1.7 nanometers wide

Envision a nanoscale wrench, capable of controlling shapes at the nanoscale level to create customized molecules. That's what Severin Schneebeli, a University of Vermont chemist and his team have developed. The opening on this mini wrench is only 1.7 nanometers, roughly a hundred-thousand-times smaller than the width of human hair.

Quantum computing breakthrough: Qubits made from standard silicon transistors

In what is likely a major breakthrough for quantum computing, researchers from the University of New South Wales (UNSW) in Australia have managed for the first time to build the fundamental blocks of a quantum computer in silicon. The device was created using standard manufacturing techniques, by modifying current-generation silicon transistors, and the technology could scale up to include thousands, even millions of entangled quantum bits on a single chip. Gizmag spoke to the lead researchers to find out more.

DARPA's fascinating self-healing body initiative – ElectRx

DARPA's ElectRx project envisions tiny devices, the width of a single nerve strand, that could be injected into the body to monitor certain conditions and then stimulate targeted nerves in response, harnessing the body’s own repair mechanisms to deal with a range of conditions like chronic pain, diabetes, rheumatoid arthritis and certain autoimmune diseases. DARPA sees the potential to create new treatments that automatically and continuously tune themselves to the needs of a specific patient.

Moon Express and Rocket Lab team up for 2017 lunar mission

Space startup Moon Express has signed a contract with Rocket Lab to help carry out three lunar missions starting in 2017. Described as the first private contract between two companies to carry out a lunar landing, the agreement will see Rocket Lab provide launch services using its Electron rocket system for the Moon Express MX-1 lunar lander as part of Moon Express's attempt win the Google Lunar Xprize.

Leukometer promises needle-free monitoring of the immune system

Keeping track of white blood cell levels in chemotherapy patients is an involved but crucially important task. The treatment can lead to suppression of the immune system, a decline in white blood cell count, which in turn can give rise to infections and other serious complications. As things stand, patients are subjected to regular blood tests as a means of keeping an eye on things, but an international team of scientists has a less invasive alternative in the works. With the ability to tally up white blood cells through the skin in real time, the new testing device can simply be stuck onto a fingertip to help clinicians tailor personalized and more timely treatments.

Hybrid solar roofing system uses heat pipes to boost efficiency

You would think that the more sunlight that hits a solar panel, the better. When it comes to efficiency though, that's not the case – as photovoltaic cells heat up their efficiency decreases. To capture that heat and put it to good use, a team of scientists from Brunel University London has created a hybrid system that turns the whole roof into a solar generator.

Tiny particles propel themselves upstream to stop severe internal bleeding

Though materials have been developed that clot blood in order to slow bleeding, when the bleeding is internal things get a little more complicated. The flow of blood makes it difficult to deliver these agents upstream to the site of the injury, but now a team of Canadian researchers says it may have a solution. It has developed a micro-sized particle that produces gas to propel itself against the tide.
