A study published by the American Academy of Neurology found that people with shorter arms and legs may be at a higher risk for developing dementia later in life. The association between short limbs and dementia risk may be due to poor nutrition in early life, affecting limb growth.
A recent study found that individuals with melanoma on their scalp or neck have lower survival rates than those with melanomas at other sites. The study analyzed data from U.S. cancer registries and found significant differences in five-year and 10-year survival rates, highlighting the importance of skin awareness and sun protection.
A new study from Johns Hopkins Medicine finds that rapid diagnosis and treatment of pain syndromes leads to better outcomes for soldiers. The study shows that establishing pain treatment centers in combat areas can dramatically increase troop levels and military success.
Researchers found that players who swing their non-kicking-side arm across their chest are the most accurate kickers, particularly over longer distances. This movement helps control body rotation and counteract leg movement, increasing accuracy and margin of error.
A study shows that a wearable robotic therapy device improved arm function by an average of 23% in severely impaired stroke patients. The device, developed by MIT engineers, uses electrical muscle activity to provide power assistance and facilitate movement.
Scientists have created a family of novel molecules called suitanes, which consist of two or more interlocked units. The researchers successfully synthesized the simplest representative of this class of compounds, a suit[2]ane, using computer simulations and self-organization processes.
Researchers at Carnegie Mellon University have developed Ballbot, a self-contained mobile robot that balances dynamically on a single sphere, enabling it to move easily among people and furniture. The robot's tall and skinny design allows it to outperform traditional statically stable robots in environments with obstacles.
Researchers discovered that octopuses generate two waves of muscle contraction to create joint-like bends in their arms, allowing for precise point-to-point movements. This human-like strategy suggests that articulated limbs controlled by joints are the optimal solution for achieving such movements.
A recent study published in the Journal of Physiology reveals that muscle fatigue can significantly impact limb control, particularly when visual cues are absent. This finding has significant implications for athletes involved in high-speed, precision-based sports like serving a tennis ball or shooting a bow and arrow.
Researchers at UC Berkeley have observed octopuses walking on two arms, using the outer halves as 'tank treads' for locomotion. This bipedal behavior may be a strategy for backing away from predators while maintaining camouflage.
