Scientists from four research institutes in the Science City Hamburg Bahrenfeld have joined forces to develop a ground-breaking experimental setup. Their new Spitrobot greatly simplifies observing changes in proteins as they carry out their functions. This makes time-resolved crystallography accessible for non-specialist research groups, as samples can now be prepared in standard labs and processed by automated established high-throughput methods elsewhere. The device will accelerate fundamental research in health and disease. The team has now presented the concept behind the…
In multiple sclerosis (MS), the immune system mistakenly attacks the brain and spinal cord, causing the complete loss of myelin. “Synthesized by specialized cells, oligodendrocytes, myelin protects nerve fibers, guarantees the good conduction of nerve impulses, and provides nutrients to the axons, Bernard Zalc recalls. This protective sheath envelops nerve fibers and is essential for their proper functioning. Its disappearance, called demyelination, causes sensory and motor symptoms: weakness of the lower or upper limbs, loss of balance, sensitivity, and vision…
More effectively measuring tissue stiffness could help treat cancer, sports injuries and more. A team of engineers at the University of California San Diego has developed a stretchable ultrasonic array capable of serial, non-invasive, three-dimensional imaging of tissues as deep as four centimeters below the surface of human skin, at a spatial resolution of 0.5 millimeters. This new method provides a non-invasive, longer-term alternative to current methods, with improved penetration depth. The research emerges from the lab of Sheng Xu, a…

Idiopathic CD4 lymphocytopenia leaves immune system vulnerable to other diseases, cancers. In an 11-year study, researchers at the National Institutes of Health have further characterized idiopathic CD4 lymphocytopenia (ICL), a rare immune deficiency that leaves people vulnerable to infectious diseases, autoimmune diseases and cancers. Researchers observed that people with the most severe cases of ICL had the highest risk of acquiring or developing several of the diseases associated with this immune deficiency. This study, published in the New England Journal…
Cocoa plays an important role in Brazilian agriculture. However, the fruit of the cacao tree (cocoa pods) is prone to fungal diseases. In the 1990s, a fungal epidemic caused cocoa production in Brazil to collapse. Nowadays, pest infestations are responsible for crop losses of up to 40 percent worldwide. In collaboration with the State University of Campinas, Brazil, researchers at the Fraunhofer IVV are looking to establish new ways of using damaged cocoa pods as part of the Damaged Beans…
Scientists at the Fraunhofer Institute for Biomedical Engineering IBMT have been working with international partners to develop a technology platform to help relieve the symptoms of muscle tremors.
