It can't be seen with a human eye. It doesn't look anything like C-3PO or R2-D2, or even BB-8. But, nevertheless, it is a robot (all 120nm of it) and its now been deemed the Smallest Medical Robot.

Researchers report a comprehensive analysis of interactions between Zika virus proteins and native human proteins. One of their findings gives insight into how Zika escapes immune signaling and where the virus proliferates inside the cell.

Pediatric researchers have identified a gene mutation that causes a serious lymphatic condition, and used that knowledge to restore normal lymphatic vessels in model animals. The laboratory findings may lead to a new therapy for patients with this type of abnormal lymphatic circulation. Abnormal lymphatic flow may sometimes cause severe symptoms, including respiratory distress, fluid accumulation and swelling in limbs and tissues.

Researchers have studied motor and cognitive effects of deep brain stimulation in patients with Parkinson's disease. Their results show that the adverse cognitive effects of deep brain stimulation are linked to a different neural pathway than that responsible for the treatment's desired motor effects. This finding will help optimize treatments for patients with Parkinson's disease.

A method can produce large quantities of pristine single-walled carbon nanotubes in select shades of the rainbow. The secret is a fine-tuned fabrication process — and a small dose of carbon dioxide. The films could find applications in touch screen technologies or as coating agents for new types of solar cells.

Scientists have identified four pervasive East Asian summer monsoon strengthening events at 1250, 1450, 1550, and 1900 CE and found that oceanic and continental settings could partially explain spatial differences in Asian summer monsoon trends at decadal to centennial scale.

The effects of island remoteness from the mainland on the number of species found on islands differs strongly for non-native compared to native species. Numbers of native species on islands decrease with greater remoteness, while numbers of non-native species increase. An international research team has uncovered this surprising finding. These findings have important implications for our understanding global biodiversity.

Collaborative music lessons in schools improve the attitudes of pupils towards their peers with autism.

Researchers have developed a novel nanoactuator system, where conformation of biomolecule can be tuned by electric field and probed using optical properties of gold nanoparticle.

Patients living with bipolar disorder and depression will soon be able to use a unique wearable sensor to safely monitor their lithium drug levels.
