Clinicians classify frailty in a symptomatic way, looking at factors such as weight loss, weakness, walking speed, and so forth. This is a method of assessment designed for use with elderly people, but researchers here apply it to a study population that includes people in the 40-60 age range. They find that […]

In this open access paper, researchers present evidence to suggest that the mitochondrial dysfunction that accompanies aging may be a meaningful cause of the loss of neurons that contributes age-related hearing loss, in the sense that it increases the incidence of necroptosis, a form of programmed cell death. Present thinking on the progressive deafness of […]

A new study led by the University of Bristol has shown a common eye condition, glaucoma could be successfully treated with a single injection using gene therapy, which would improve treatment options, effectiveness and quality of life for many patients. Glaucoma affects over 64 million people worldwide and is a […]

Can staying up late make you fat? A growing body of research has suggested that poor sleep quality is linked to an increased risk of obesity by deregulating appetite, which in turn leads to more calorie consumption. But a new study published in PLOS Biology found that the direction of this […]

National Eye Institute (NEI) researchers profiling epigenomic changes in light-sensing mouse photoreceptors have a clearer picture of how age-related eye diseases may be linked to age-related changes in the regulation of gene expression. The findings, published online in Cell Reports, suggest that the epigenome could be targeted as a therapeutic […]

From an evolutionary perspective, human pregnancy is quite strange, says University at Buffalo biologist Vincent Lynch. “For example, we don’t know why human women go into labor,” Lynch says. “Human pregnancy tends to last longer than pregnancy in other mammals if you adjust for factors like body size. The actual […]

Experts at the University of Tokyo have identified a new protein in the pathway that leads to Alzheimer’s disease. Researchers used the “molecular scissors” of CRISPR/Cas9 to search for new genes related to neurodegenerative disease. The exact causes of Alzheimer’s disease remain unknown, but one of the most well- supported […]

Viruses are nature's Trojan horses: They gain entrance to cells, smuggle in their genetic material, and use the cell's own machinery to replicate. For decades, scientists have studied how to minimize their deleterious effects and even repurpose these invaders to deliver not their own viral genome, but therapeutics for treating […]

A team of scientists led by the University of Michigan Rogel Cancer Center and Case Comprehensive Cancer Center has identified the binding site where drug compounds could activate a key braking mechanism against the runaway growth of many types of cancer. The discovery marks a critical step toward developing a potential new class of anti-cancer drugs […]

The insides of living cells can be seen in their natural state in greater detail than ever before using a new technique developed by researchers in Japan. This advance should help reveal the complex and fragile biological interactions of medical mysteries, like how stem cells develop or how to deliver […]

A blood test may be able to detect the most common form of pancreatic cancer while it is still in its early stages while also helping doctors accurately stage a patient’s disease and guide them to the appropriate treatment. A multidisciplinary study from the University of Pennsylvania found the test – known […]

Even after they quit smoking, some people can’t breathe easy. The chronic bronchitis and emphysema that can afflict long-term smokers, called chronic obstructive pulmonary disease COPD, never goes away and may even progress despite the smoker quitting. Now, researchers from UConn Health and the University of Houston report the journal […]
