Many cells in the body must pass through tissue, which sometimes requires them to get out of tight corners. An international research team co-​led by ETH Zurich has now examined how cells recognise and escape from such bottlenecks. Among the results of the team’s work are new pointers for how […]

Are there common regulators of aging to be found among transcription factors? Sweeping, complex, tissue-specific and species-specific changes in gene expression take place over the course of aging. If these are reactions to comparatively straightforward processes of molecular damage at the root of aging, processes that are similar between species, […]

The immune system is inconveniently complicated. Aging is also inconveniently complicated. The overlap between the two is a particularly dark forest for the research community, with few well-tracked paths. The fine details of how exactly the immune system becomes dysfunctional with age, and the sizable variation in those details between […]

Researchers here provide an interesting demonstration of the beneficial role of transient cellular senescence in injury. Applying senolytics to selectively destroy senescent cells immediately following traumatic injury greatly worsens the consequences. Senescent cells are harmful when they build up and linger in tissues over the course of later life. The […]

Heart failure is a debilitating condition that impairs quality of life and shortens life span. Rates of heart failure continue to rise to epidemic levels, in parallel with its risk factors—obesity, diabetes, and hypertension. In essence, heart failure is a condition in which the heart has difficulty generating the pumping […]

The National Institutes of Health recently announced the project’s funding: $4 million over five […]

There are more than 5 million Americans living with Alzheimer’s disease, and 50 million with other dementias, according to figures from the Alzheimer’s Association. Research into these diseases and how to prevent them is key as more and more Americans live longer, raising their risk for developing cognitive impairment. In a new […]

A rare genetic condition which causes inflammatory bowel disease can be successfully treated by bone marrow transplant, according to the University of Manchester and Manchester University NHS Foundation Trust researchers. The disease, called G6PC3 deficiency, affects around one in a million people and causes inflammation of the bowel, as well as lung infections. The […]

Tool developed at MIT simultaneously measures chemical and electrical brain signals, revealing unexpectedly complex relationship between brain signals. As the brain processes information, electrical charges zip through its circuits and neurotransmitters pass molecular messages from cell to cell. Both forms of communication are vital, but because they are usually studied […]

Boosting the efficiency of single-cell RNA-sequencing helps reveal subtle differences between healthy and dysfunctional cells. Sequencing RNA from individual cells can reveal a great deal of information about what those cells are doing in the body. MIT researchers have now greatly boosted the amount of information gleaned from each of […]

The closer people are physical to one another, the higher the chance for exchange, of things like ideas, information, and even infection. Now researchers at MIT and Boston Children’s Hospital have found that, even in the microscopic environment within a single cell, physical crowding increases the chance for interactions, in […]
