Game theory suggests more efficient cancer therapy

Cancer cells not only ravage the body – they also compete with each other. Cornell mathematicians are using game theory to model how this competition could be leveraged, so cancer treatment – which also takes a toll on the patient’s body – might be administered more sparingly, with maximized effect. […]

The mystery of the immortal

Biologist Cornelia Dulac has been missing since 2014. Her audiotapes were discovered at a remote cabin in Eastern Finland together with a fully-equipped research laboratory and a year’s supply of food. It is obvious that something had deviated from Dulac’s plans. She had been researching hydra, an immortal freshwater polyp. The authors […]

Indicators of Frailty Start to Appear Early, Probably Due to Lifestyle Choices

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 […]

Mitochondria in Age-Related Hearing Loss

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 […]

Study shows glaucoma could be successfully treated with gene therapy

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 […]

Obesity linked to sleep loss? Researchers identify how metabolism regulates sleep

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 […]

NEI researchers link age-related DNA modifications to susceptibility to eye disease

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 […]

Human pregnancy is weird. A new study adds to the mystery

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 […]

CRISPR helps identify potential Alzheimer's-related protein

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 […]

High-Throughput Method Speeds Discovery of Improved Vectors For Gene Delivery To Diverse Brain Cell Types

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 […]
