Regenerative medicine could slow the clock on degenerative diseases that often ravage the golden years, a Mayo Clinic study finds. Life span has nearly doubled since the 1950s, but health span — the number of disease-free years — has not kept pace. According to a paper published in NPJ Regenerative Medicine., people are generally living longer, but the last decade of life is often racked with chronic, age-related diseases that diminish quality of life. These final years come with a great cost burden to society.
Researchers contend that new solutions for increasing health span lie at the intersection of regenerative medicine research, anti-senescent investigation, clinical care and societal supports. A regenerative approach offers hope of extending the longevity of good health, so a person’s final years can be lived to the fullest.
Robotic GPS system for early lung cancer detection.
Lung cancer typically is diagnosed at a later stagethan other malignancies, due to the lack of early warning indications. In 2020 it was China’s most common cancer and the leading cause of cancer-associated mortality. LungHealth MedTech, a medical robotics company in Shanghai, has developed a robotic-assisted bronchoscopy platform that can address some of the current diagnostic challenges and treatment limitations.

The American Heart Association (AHA) recently revised its checklist for achieving optimal heart health, introducing its new Life’s Essential 8. The list replaces the AHA’s decade-old Life’s Simple 7.
Sleep health is the new addition to the cardiovascular health scoring tool, which now advises that adults get seven to nine hours per night. The organization updated four of the categories:

Keeping bones healthy is important for everyone and especially important for people with Parkinson’s. We share some top tips for keeping your bones in tip top condition.
Bone health really means having ‘healthy bones’. Healthy bones are strong enough to prevent fractures, for example when we have a fall. Our bones are more healthy when we have enough calcium in our diet (from milk, and dairy products like cheese) and when we use our arms and legs (such as with exercise).

As humans live longer, they’re at increased risk of developing devastating NEURODEGENERATIVE diseases, such as Alzheimer’s—in a treatment landscape with few options and little hope. At Scripps Research, scientists are closer than ever to understanding how these diseases harm the brain and identifying possible drugs to stop them.
“This early preclinical work may identify proteins that protect against cognitive loss. We know it’s a long path to get to a drug, but we’re creating the foundation. We know there’s an entire landscape of potential molecular interactions that maintain healthy synapses, and any of these proteins could be a drug target.”— Hollis Cline, PhD
Take an animated look inside the neuron, and learn how scientists are addressing brain disease. With approximately 86 billion neurons in the brain, humans contain the most complex communications network imaginable. To address diseases of brain development and degeneration, neuroscientists are investigating how and why this network breaks down, and what can be done to repair it.
One area of study is dendrites, which are the tree-like structures of neurons, that receive electrical impulses. Researchers are carefully mapping out brain circuits and uncovering how connectivity changes can result in defects of the visual system or behavioral problems. The core section of the neuron is the cell body. Genetic engineering tools are revealing how mutations impact brain development and contribute to autism spectrum disorder or rare, inherited forms of neurological disease.
The transmission of nerve impulses occurs along the axon, which is insulated, much like an electrical wire, by a fatty layer called the myelin sheath. Scientists have invented a medicine to stop the immune system from mistakenly attacking this layer, which occurs during multiple sclerosis. Other molecules currently in development instruct the body to regenerate the sheath and repair damage. The axon also transports valuable cellular cargo, such as neurotransmitters, along tracks from one end of the neuron to the other.
Researchers are testing drug candidates for their ability to remove molecular traffic jams when this transport system fails, as often occurs in Parkinson’s and Alzheimer’s disease. The axon terminals make connections called synapses with other cells, using neurotransmitters as signals. Some scientists are evaluating how finely tuning the receptors for these chemicals could ease depression and anxiety.
Others are finding ways to promote the regrowth of lost synapses, which could halt neurodegeneration. From genetics to behavior, neuroscience is accelerating new interventions for the most challenging disorders of the nervous system.
