Researchers report the origin and immunoregulatory function of monocytes

Non-classical monocytes were long thought to play a purely surveillance role in the immune system. With the aid of a novel marker (PD-L1), Ludwig-Maximilians-Universitaet (LMU) researchers in Munich have now shown that they are directly involved in the regulation of immune response.

Climbing droplets driven by mechanowetting on transverse waves

Modern applications use self-cleaning strategies and digital microfluids to control individual droplets of fluids on flat surfaces but existing techniques are limited by the side-effects of high electric fields and high temperatures. In a new study, Edwin De Jong and co-workers at the interdisciplinary departments of Advanced Materials, Mechanical Engineering and Complex Molecular Systems developed an innovative "mechanowetting" technique to control droplet motion on changing surfaces based on the interfacial surface tension.

Bacteria live on our eyeballs—and understanding their role could help treat common eye diseases

You may be familiar with the idea that your gut and skin are home to a collection of microbes—fungi, bacteria and viruses—that are vital for keeping you healthy. But did you know that your eyes also host a unique menagerie of microbes? Together, they're called the eye microbiome. When these microbes are out of balance—too many or too few of certain types—eye diseases may emerge.

Major HIV drug requires vigilance, study says

A study lead by researchers at the Institute of HIV Research, Medical Faculty of UDE and University Hospital Essen reports a potential toxicity of integrase inhibitors. Integrase inhibitors (INSTI) are a preferred drug for inclusion in anti-retroviral therapy regimens given its tolerability, efficacy and high resistance barrier. INSTI have been found to improve and prolong lives of millions of people living with HIV who suffer side-effects and resistance to treatment. However, recent laboratory data suggest that INSTI may not be as safe as suggested.

Newly discovered immune cells at the frontline of HIV infection

Researchers at The Westmead Institute for Medical Research have discovered brand new immune cells that are at the frontline of HIV infection. Known as CD11c+ dendritic cells, these new cells are more susceptible to HIV infection and can then transmit the virus to other cells.

Spintronic memory cells for neural networks

In recent years, researchers have proposed a wide variety of hardware implementations for feed-forward artificial neural networks. These implementations include three key components: a dot-product engine that can compute convolution and fully-connected layer operations, memory elements to store intermediate inter and intra-layer results, and other components that can compute non-linear activation functions.

Mystery of immunosuppressive drug's biosynthesis finally unlocked

Mycophenolic acid (MPA), discovered in 1893, was the first natural antibiotic to be isolated and crystallized in human history. Today, this fungal metabolite has been developed into multiple first-line immunosuppressive drugs to control immunologic rejection during organ transplantation and treat various autoimmune diseases.

Possible signal pathway in the fight against obesity-related fatty liver disease identified

A research group from the Medical University of Vienna reports how the hormone leptin stimulates the liver to export lipids and reduce the fat production in the liver. This occurs due to the activation of neurons in the brain stem. These findings provide new approaches for the fight against non-alcoholic fatty liver disease, which often occurs in connection with obesity. The results were just published in Nature Communications.

Skinflow: A soft robotic skin based on liquid transmission

Researchers at the Bristol Robotics Laboratory and the University of Bristol have recently developed a new soft robotic skin-like sensor that is based on fluidic transmission. This sensor, presented at the second IEEE International Conference on Soft Robotics (RoboSoft), could have interesting applications in a variety of fields, ranging from robotics to virtual reality (VR).
