Patients connected to a new prosthetic system said they ‘felt’ their hands for the first time since they lost them in accidents. In the ensuing months, they began feeling sensations that were familiar and were able to control their prosthetic hands with more — well — dexterity.
For the first time, robotic prostheses controlled via implanted neuromuscular interfaces have become a clinical reality. A novel osseointegrated (bone-anchored) implant system gives patients new opportunities in their daily life and professional activities.
Astronomers working with NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) have found a pulsating dead star beaming with the energy of about 10 million suns. The object, previously thought to be a black hole because it is so powerful, is in fact a pulsar — the incredibly dense rotating remains of a star.
Researchers are decoding the structure of the large ribosomal subunit of the mitochondria at an atomic level, thereby providing insight into the molecular architecture of this ribosome with implications for a better understanding of the mode of action of antibiotics.
A government program provided free, targeted health insurance to the poor — resulting in a significant saving of lives. “This World Bank study clearly shows how this program benefits the health of the poor in Karnataka,” said the state’s Minister of Health and Family Welfare. “It provides hospital care that the poor would have difficulty receiving without the help of the scheme.”
A fundamental theory about how our thymus educates our immune police appears to be wrong, scientists say. The finding provides more insight into immunity that could one day enable a new approach to vaccines that steer the thymus to produce more of whatever T cell type a patient needs: more effector cells if they have a bad infection or cancer, more regulatory T cells if they are experiencing autoimmune diseases like arthritis and multiple sclerosis.
