Medical Xpress / How age affects vaccine responses and how to make them better
As flu season approaches and public health officials roll out their annual push for vaccination, Allen Institute scientists are learning why vaccines can trigger a weaker response in older adults, around age 65, and what ...
Medical Xpress / The minimal circuit of the circadian clock: Just four neurons keep fruit flies on schedule, study finds
A tiny neural network is sufficient to control the daily rhythm of the fruit fly, Drosophila melanogaster. Researchers at the University of Würzburg have shown that only four specialized nerve cells are necessary to drive ...
Medical Xpress / Changing the 'packaging' of DNA in neurons can turn memories on or off in mice
Our experiences leave traces in the brain, stored in small groups of cells called engrams. Engrams are thought to hold the information of a memory and are reactivated when we remember, which makes them very interesting for ...
Medical Xpress / New technology restores chemotherapy effectiveness against resistant cancer cells
Scientists from King's College London have successfully applied a new technology that disarms one of the most potent weapons cancer cells use to weaken the effects of chemotherapy drugs.
Medical Xpress / Discovery of 'doorstop' for brain's electrical gates may open path to new therapies for neurodegenerative conditions
As information zings from cell to cell inside the brain, bursts of electricity spur its transmission. At Cold Spring Harbor Laboratory (CSHL), scientists have turned their attention to the tiny pores that let charged ions ...
Medical Xpress / Common genetic causes across motor neuron diseases identified
Motor neuron diseases, such as amyotrophic lateral sclerosis (ALS) and hereditary spastic paraplegia (HSP), share physical similarities but have been largely viewed as genetically distinct. However, an analysis led by investigators ...
Medical Xpress / MAGIC: AI-assisted 'laser tag' illuminates cancer origins
The human body relies on precise genetic instructions to function, and cancer begins when these instructions get scrambled. When cells accumulate genetic errors over time, they can break free of the normal controls on their ...
Medical Xpress / Novel molecular mechanisms shape neuron identity in retinal cells
A recent study led by Tiffany Schmidt, Ph.D., associate professor of Ophthalmology and of Neurobiology in the Weinberg College of Arts and Sciences, has discovered previously unknown cellular mechanisms that shape neuron ...
Medical Xpress / Computational model helps personalize neurostimulation therapy for atrial fibrillation
Atrial fibrillation (AFib) is a cardiac disorder in which the chambers of the heart beat rapidly and irregularly. It's the most common type of arrhythmia and the leading cardiac cause of stroke.
Medical Xpress / Implantable 'CANDI' wafer shows promise for preventing glioblastoma recurrence
Glioblastoma is an aggressive brain cancer that almost always recurs after surgery and radiochemotherapy. Now, researchers have developed a biodegradable implant that can be placed directly into the brain cavity after tumor ...
Medical Xpress / Fruit flies offer new insights into how Alzheimer's disease risk genes affect the brain
Scientists have identified hundreds of genes that may increase the risk of developing Alzheimer's disease but the roles these genes play in the brain are poorly understood. This lack of understanding poses a barrier to developing ...
Medical Xpress / Online tool identifies and ranks community factors that predict cancer disparities
A new study published in JAMA Network Open by the Harvey L. Neiman Health Policy Institute reveals poverty, environmental risks, housing issues, and physical inactivity are top-ranking community-level predictors of disparities ...
