Rathke’s cleft cysts are benign, fluid-filled growths that develop in the pituitary gland, a small oval-shaped gland near the underside of the brain. Usually, these cysts don’t cause symptoms.  However, if they become large enough to compress the organ and surrounding tissues, then they can cause problems with vision and […]

Biology is rife with examples of collective behavior, from flocks of birds and colonies of bacteria to schools of fish and mobs of people. In a study with implications from oncology to ecology, researchers from Rice University and the University of Georgia have shown that data science can unlock subtle […]

Rare inherited mutations in the body’s master regulator of the DNA repair system – the TP53 gene – can leave people at a higher risk of developing multiple types of cancer over the course of their lives. Now, for the first time, a team led by researchers in the Basser Center for BRCA at […]

Seniors who can identify smells like roses, turpentine, paint-thinner and lemons, and have retained their senses of hearing, vision, and touch may have half the risk of developing dementia as their peers with marked sensory decline. In a study by UC San Francisco, researchers tracked close to 1,800 participants in […]

A new study reveals intricate details about the biology of the huntingtin protein (HTT), which is responsible for Huntington’s disease. The research focuses on axonal transport — the way in which vital materials travel along pathways called axons inside nerve cells, or neurons. Scientists found that HTT sometimes journeys along these […]

A new blood test that reliably predicts outcomes for heart failure patients could lead to new diagnostics and treatments for COVID-19 patients as well, according to newly published research from cardiologists at the University of Alberta. The researchers examined circulating angiotensin peptide levels in the blood of 110 people who were experiencing […]

Preliminary findings from Harvard Medical School researchers at Massachusetts Eye and Ear may pave the way for trials to test bone density medications for hearing loss. Hearing loss caused by damaged nerves, whether from sound exposure or aging, is irreversible. There are currently no medications approved by the Food and […]

In a new study of human ear tissues, hearing scientists at Harvard Medical School and Massachusetts Eye and Ear have demonstrated that age-related hearing loss, also called presbycusis, is mainly caused by damage to hair cells, the sensory cells in the inner ear that transform sound-induced vibrations into electrical signals […]

As the most common form of dementia and the sixth-leading cause of death in the U.S., Alzheimer's disease is not foreign to Americans. Many of us know someone battling the disease— a disease that doctors are still continuing to understand. While the majority of previous research has been focused on treatment, researchers […]

Osteoarthritis – the most common chronic joint condition, which causes joints to become painful and stiff. It’s been known for a long time that osteoarthritis is a somewhat of an occupational condition – people from some jobs are more likely to suffer from it. Now scientists the Universities of Sydney, […]

Before the days of rote texting and email, if you wanted to communicate with a friend you might have personalized and assembled a physical letter. Similarly, the individual cells in our bodies communicate with each other by sending tailored “letters”—not with paper and pen, but in the form of proteins […]

The antidepressant fluoxetine has been suggested as a means to improve brain recovery after acute stroke. However, a large randomized study on stroke patients at 35 Swedish hospitals shows that the drug has no such effect. The study, which was led by researchers at Karolinska Institutet, is published in The […]

Across the globe, approximately 50 million people are living with dementia. The two most common forms are Alzheimer’s disease and frontotemporal lobar degeneration (FTLD), which develop when neurons in specific parts of the brain stop functioning – triggering memory loss and other behavioral or personality changes. Without a cure, the […]

In addition to responding to electrical and chemical stimuli, many of the body’s neural cells can also respond to mechanical effects, such as pressure or vibration. But these responses have been more difficult for researchers to study because there has been no easily controllable method for inducing such mechanical stimulation […]

A study by MIT neuroscientists into how seemingly similar neuronal subtypes drive locomotion in the fruit fly reveals an unexpected diversity as the brain’s commands were relayed to muscle fibers. A sequence of experiments found a dramatic difference between the two nerve cells: One neuron scrambled to adjust to different […]

Alzheimer's disease progressively degrades a person's memory and cognitive abilities, often resulting in dementia.
