Bone-anchored leg prostheses also prove to be a valuable procedure after 5-year follow-up
After above-knee amputation, there is the option of a prosthesis that is placed directly in the thigh bone. Despite the fact that bone-anchored prostheses have been used for thirty years, researchers at Radboudumc have published the first long-term evaluation. It turns out that the procedure is not without stoma problems, but that these can usually be treated with simple measures and that the implant leads to a permanent improvement in mobility and quality of life.

Study suggests embryos could be susceptible to coronavirus
Genes that are thought to play a role in how the SARS-CoV-2 virus infects our cells have been found to be active in embryos as early as during the second week of pregnancy, say scientists at the University of Cambridge and the California Institute of Technology (Caltech). The researchers say this could mean embryos are susceptible to COVID-19 if the mother gets sick, potentially affecting the chances of a successful pregnancy. (2020-08-04)

How thoughts could one day control electronic prostheses, wirelessly
The current generation of neural implants record enormous amounts of neural activity, then transmit these brain signals through wires to a computer. But, so far, when researchers have tried to create wireless brain-computer interfaces to do this, it took so much power to transmit the data that the implants generated too much heat to be safe for the patient. A new study suggests how to solve his problem -- and thus cut the wires. (2020-08-04)
