Neurons in the eye change on the molecular level when they are exposed to prolonged light. The researchers could identify that a feedback signalling mechanism is responsible for these changes. The innate neuronal property might be utilized to protect neurons from degeneration or cell death in the future. Changes in the functional connections between neurons – ‘synapses’ – contribute to our ability to adapt to...

Breast cancer patients often display mild cognitive defects even before the initiation of chemotherapy. A new study by Ludwig-Maximilians-Universitaet (LMU) in Munich researchers now attributes the syndrome to post-traumatic stress induced by diagnosis of the disease.

Oxidative stress is the underlying mechanism in the development of many diseases, including neurodegenerative diseases, and is a part of the aging process.  It results from accumulation of reactive oxygen and nitrogen species (ROS/NOS), which cause oxidative damage to proteins, nucleic acids and lipids.  Since the discovery of these molecules, much research has focused on targeting oxidative stress as a therapeutic strategy for...

The phenomenon of "intra-tumour heterogeneity" whereby tumours contain sub-populations of cells carrying different set of mutations is suspected to be associated with poorer clinical outcomes. Often therapies are targeted at specific mutations and are not fully effective in the face of several different mutations. In a recent study in the journal PLoS Medicine, a new method called MATH (mutant-allele tumour heterogeneity) for...

“There are several aspects of western lifestyle that have been hypothesized to alter the gut microbiome and decrease diversity,” explains senior author Jens Walter of the University of Alberta Department of Agricultural, Food & Nutritional Science. “These include diet, sanitation, and clinical practices such as antibiotic use and caesarean sections, but we lack a conceptual understanding of how our microbiomes are...

California man Mike May made international headlines in 2000 when his sight was restored by a pioneering stem cell procedure after 40 years of blindness. But a study published three years after the operation found that the then-49-year-old could see colors, motion and some simple two-dimensional...
