DNA methylation: The role it plays in aging cells Posted: 18 Nov 2014 08:00 AM PST Although every person's DNA remains the same throughout their lives, scientists know that it functions differently at different ages. As people age, drastic changes occur in their DNA methylation patterns, which are thought to act as a "second code" on top of the DNA that can lock genes in the on or off position. However, what the consequences of these changes are remains a mystery.

Soy spells fewer hot flashes for certain women Posted: 18 Nov 2014 07:59 AM PST Does soy in the diet help with hot flashes? It does, but only for women whose bodies can produce the soy metabolite equol, reports a new study.

Training can lead to synesthetic experiences: Does learning the 'color of' specific letters boost IQ? Posted: 18 Nov 2014 07:55 AM PST A new study has shown for the first time how people can be trained to 'see' letters of the alphabet as colors in a way that simulates how those with synesthesia experience their world.

New clue in celiac disease puzzle: Cause of oat toxicity explained Posted: 18 Nov 2014 07:55 AM PST Researchers have identified why some people with celiac disease show an immune response after eating oats. The researchers have identified the key components in oats that trigger an immune response in some people with celiac disease.

Ferroptosis, a novel form of non-apoptotic cell death, holds great therapeutic potential Posted: 18 Nov 2014 04:26 AM PST Ferroptosis is a recently recognized form of regulated necrosis. Up until now, this form of cell death has only been thought to be a possible therapeutic approach to treat tumor cells. Yet, ferroptosis also occurs in non-transformed tissues as demonstrated by this study, thus implicating this cell death pathway in the development of a wide range of pathological conditions. More specifically, the deletion of the ferroptosis-regulating enzyme Gpx4 in a pre-clinical model results in high ferroptosis rates in kidney tubular epithelial cells causing acute renal failure.

Mechanisms behind 'Mexican waves' in brain revealed by scientists Posted: 18 Nov 2014 04:26 AM PST Scientists have revealed the mechanisms that enable certain brain cells to persuade others to create 'Mexican waves' linked with cognitive function. Inhibitory neurons can vibrate and they are equipped with mechanisms that enable them to persuade networks of other neurons into imitating their vibrations -- setting off 'Mexican waves' in the brain. The scientists believe these collective, oscillating vibrations play a key role in cognitive function. Their research sheds light on how inhibitory neurons use different communication processes to excitatory neurons, which share information via an internal pulsing mechanism.

Unexpected cross-species contamination in genome sequencing projects Posted: 18 Nov 2014 04:26 AM PST As genome sequencing has gotten faster and cheaper, the pace of whole-genome sequencing has accelerated, dramatically increasing the number of genomes deposited in public archives.
