Researchers identified previously unseen changes in motor coordination that result from incomplete spinal cord injuries. Motor units, nerve-to-muscle connections, struggle to spread signals smoothly across muscles at low exertion after the injury.
Researchers developed an iEMG classifier framework for detecting myopathy and neuropathy, achieving high accuracy in three muscle types and low computational time. The study showed promise for real-time implementation, aiding clinicians in making quick and accurate diagnoses.
Researchers found that high-load training conditions the nervous system to transmit electrical signals from the brain to muscles, increasing force production. The study replicated previous findings with similar growth in muscle but greater strength gains in the high-load group.
A University of Guelph professor found that elite athletes in their 80s and 90s have stronger legs and more muscle mass than non-athletes. The study, published in the Journal of Applied Physiology, compared world-class track and field athletes with individuals of the same age who are living independently.
Researchers found that motor unit firing patterns varied significantly across the menstrual cycle, with a significant increase in the late luteal phase, potentially affecting joint stability and injury risk. The study suggests that hormone fluctuations may play a role in knee injuries among female athletes.
Researchers at Empa have successfully designed a molecule with four rotating motor units that can travel straight ahead in a controlled manner. The smallest electric car in the world, measuring approximately 4x2 nanometres, requires refueling with electricity after every half revolution of its wheels.
Researchers have discovered that the DNA unwinding protein RecBCD uses two motors to move along the DNA, one from 3' to 5' and another from 5' to 3'. This allows the complex to travel long distances before stopping or getting derailed.
