Researchers at the Max Planck Institute for Intelligent Systems in Germany have developed powerful nanopropellers that can be steered into the interior of cells to deliver gene therapy. The magnets that these devices, each about the size of a bacteria, are made of were created for the first time for this very task. Most powerful...
By Michael Irving In the not too distant future, tiny robots could be delivering drugs inside our bodies, but there are still a few hurdles to clear before we realize that scenario. Now researchers have developed corkscrew microrobots that drill into cancer and hold fast while they drop off the drug payload, preventing them being...
Concussion symptoms–such as loss of balance, hazy comprehension, sleep disturbance and ability to walk straight–can be reversed by a new type of magnetic stimulation, research at the University of Saskatchewan (USask) shows. Magnetic stimulation using a laptop-style device for 20 minutes per day improved the ability of rodents with concussion to walk in a straight line, navigate a...
1. Introduction Transcranial magnetic stimulation (TMS) is a non-invasive and painless technique to stimulate the human brain with an electromagnetic coil placed on the scalp. TMS is widely used as a tool to assess corticospinal excitability, a commonly used marker for corticospinal plasticity (Hallett, 2000). With the coil placed over the primary motor cortex a twitch in a contralateral muscle...
Researchers at Aalto University and the University of Helsinki have succeeded for the first time ever in affecting metacognition of a tactile working memory task by combining neural pathway imaging and magnetic stimulation of the brain. Understanding brain function might help in the development of new treatments for neuropsychiatric illnesses in the future. By combining...
