Researchers at the University of Pittsburgh School of Medicine have developed a monkey that can feed itself using only its brain signals. The advancement in brain-machine interface technology could lead to better prosthetics for people with spinal cord injuries and those with locked-in conditions.
The Phoenix Mars Mission will investigate the Martian environment, searching for signs of climate cycles and microbial life. The spacecraft will collect soil and ice samples and analyze them to understand the Red Planet's history.
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.
A study of 4,223 individuals found that subclavian artery stenosis is a significant risk factor for hypertension. Patients with peripheral arterial disease are five times more likely to have SS.
A study of 676 individuals with PAD found that those with lower ABI levels had greater declines in walking endurance and speed. Leg symptoms, particularly pain on exertion, also predicted rates of functional decline.
A 365-million-year-old fossil discovery in Pennsylvania provides insight into the evolution of limbs from fins. The humerus specimen shares features with both primitive fish fins and true limb bones.
Researchers at Northwestern University found that imagining movement of affected limbs can improve stroke rehabilitation. The study used a motor imagery training program with patients experiencing hemiparesis, resulting in increased assessment scores and functionality.
Researchers studied 13 young adults with muscle weakness after stroke and found that shaping therapy improved arm movement and motor activity. The study showed significant improvements in the amount of use and quality of movement, with stable results during a four-week follow-up.
Acer's process creates a micro-porous calcium phosphate coated polymer 'bone' that allows natural bone growth, reducing recovery time to 18 months. The technology, funded by the Navy Small Business Technology Transition program, has shown success in animal testing and tissue cultures.
A study of 141 whiplash patients and 40 ankle injury patients found that whiplash pain was more frequent but similar in intensity to ankle injuries. Pain improved significantly over time, with most patients returning to work within a year.
In a breakthrough study, monkeys were trained to move balls around on a screen using brain signals, achieving accuracy and speed comparable to normal arm movements. The technique has implications for people with paralysis who may be able to learn to control prosthetic limbs through thought control.
Researchers from The Neurosciences Institute and Arizona State University successfully implanted electrodes in monkey brains to decode neural signals controlling arm movements. This breakthrough technology aims to restore movement to individuals with paralyzed arms through a 'neural bypass'.
HIV-infected individuals taking antiretroviral therapy experience changes in fat distribution, cholesterol, and glucose metabolism, leading to anxiety-provoking body shape changes. Dr. Kingsley's proposed definition guides diagnosis and monitoring of HIV-associated lipodystrophy syndrome.
The all-terrain wheelchair is designed to cross potholes, hobble over obstacles, and cruise along sandy beaches. It features powered rear wheels and robotic arms that anchor the chair like crutches or ski poles.
