Researchers at the National Institute of Standards and Technology (NIST) have developed a new method of 3D-printing gels and other soft materials. Published in a new paper, it has the potential to create complex structures with nanometer-scale precision. Because many gels are compatible with living cells, the new method could jump-start the production of soft tiny medical devices such as drug delivery systems or flexible electrodes that can be inserted into the human body.

Carnegie Mellon University’s Maysam Chamanzar and his team have invented an optical platform that will likely become the new standard in optical biointerfaces. He’s labeled this new field of optical technology “Parylene photonics,” demonstrated in a recent paper in Nature Microsystems and Nanoengineering.

There is a growing and unfulfilled demand for optical systems for biomedical applications. Miniaturized and flexible optical tools are needed to enable reliable ambulatory and on-demand imaging and manipulation of biological events in the body. Integrated photonic technology has mainly evolved around developing devices for optical communications...

Plasma cells at the center of a novel treatment approach. Researchers from Charité — Universitätsmedizin Berlin and the Deutsches Rheuma-Forschungszentrum (DRFZ) Berlin, a Leibniz Institute, have successfully treated two patients with the autoimmune disease systemic lupus erythematosus. Using daratumumab, a monoclonal antibody which targets specific immune cells known as plasma cells, the researchers were able to modulate the abnormal immunological memory processes found in these patients. Treatment induced sustainable clinical responses and resulted in a reduction in systemic inflammation. The results of this research have been published in the New England Journal of Medicine.

The body’s immunological memory enables the immune system to respond more rapidly and effectively to pa...

Two pain blocking peptides were found in the venom from the Venezuelan Pinkfoot Goliath tarantula. Molecules from the venom of one of the world’s largest spiders could help University of Queensland-led researchers tailor pain blockers for people with irritable bowel syndrome (IBS).

Researchers screened 28 spiders, with the venom of the Venezuelan Pinkfoot Goliath tarantula — which has a leg-span of up to 30 centimetres — showing the most promise.

The team led by Professor Richard Lewis from UQ’s Institute for Molecular Bioscience in collaboration with Flinders University’s Professor Stuart Brierley and the South Australian Health and Medical Research Institute hopes to find effective pain relief for chronic intestinal pain.

“All pains are complex but gut pain is particularly ...
