Methylome modifications offer new measure of a person's biological age

Women live longer than men. Individuals can appear or feel years younger - or older - than their chronological age. Diseases can affect our aging process. When it comes to biology, our clocks clearly tick differently.

Iridoid synthase can make powerful chemicals from catnip to vinblastine

Scientists have discovered an enzyme used in nature to make powerful chemicals from catnip to a cancer drug, vinblastine. The discovery opens up the prospect of producing these chemicals cheaply and efficiently.

Obesity and oxidative stress: an interview with Dr Elizabeth New

Even though oxygen is essential for us to live, it can react with other compounds in the body to produce molecules called free radicals, which are highly reactive and damaging.

Important knowledge about how stem cells develop best into insulin-producing cells

Scientists from The Danish Stem Cell Center (DanStem) at the University of Copenhagen are contributing important knowledge about how stem cells develop best into insulin-producing cells. In the long term this new knowledge can improve diabetes treatment with cell therapy.

Max Planck Institute develops neural event-triggered functional magnetic resonance imaging

While in deep dreamless sleep, our hippocampus sends messages to our cortex and changes its plasticity, possibly transferring recently acquired knowledge to long-term memory. But how exactly is this done? Scientists from the Max Planck Institute for Biological Cybernetics have now developed a novel multimodal methodology called "neural event-triggered functional magnetic resonance imaging" (NET-fMRI) and presented the very first results obtained using it in experiments with both anesthetized and awake, behaving monkeys.

Human Food Project, University of Colorado Boulder launch American Gut

Ever wondered who is living in your gut, and what they're doing? The trillions of microbial partners in and on our bodies outnumber our own cells by as many as 10 to 1 and do all sorts of important jobs, from helping digest the food we eat this Thanksgiving to building up our immune systems.

Scientists discover telomerase as cause of chronic inflammation in human cancers

A*STAR scientists have identified the enzyme, telomerase, as a cause of chronic inflammation in human cancers. Chronic inflammation is now recognized as a key underlying cause for the development of many human cancers, autoimmune disorders, neurodegenerative diseases, and metabolic diseases such as diabetes.

Crucial link between protein synthesis and autism spectrum disorders

Researchers from McGill University and the University of Montreal have identified a crucial link between protein synthesis and autism spectrum disorders (ASD), which can bolster new therapeutic avenues.

Study sheds light on how neural ensembles form thoughts

One of the biggest puzzles in neuroscience is how our brains encode thoughts, such as perceptions and memories, at the cellular level. Some evidence suggests that ensembles of neurons represent each unique piece of information, but no one knows just what these ensembles look like, or how they form.

Yawning could be linked to fetal development

The 4D scans of 15 healthy fetuses, by Durham and Lancaster Universities, also suggest that yawning is a developmental process which could potentially give doctors another index of a fetus' health.

Heidelberg researchers uncover function of specific molecular chaperones

Clumped proteins can be dissolved with the aid of cellular repair systems - a process of critical importance for cell survival especially under conditions of stress. Heidelberg researchers have now decrypted the fundamental mechanism for dissolving protein aggregates that involves specific molecular chaperones.

Study provides new insight into human cognitive function and risk for neurological diseases

Short snippets of DNA found in human brain tissue provide new insight into human cognitive function and risk for developing certain neurological diseases, according to researchers from the Departments of Psychiatry and Neuroscience at Mount Sinai School of Medicine. The findings are published in the November 20th issue of PLoS Biology.

MicroRNAs in ovarian cancer cells promote tumor growth

Unraveling the mechanism that ovarian cancer cells use to change normal cells around them into cells that promote tumor growth has identified several new targets for treatment of this deadly disease.

Inhaled nitric oxide reduces adverse effects of stored blood transfusion in mice

Inhaled nitric oxide reduced the adverse effects of transfusing stored blood in mice, according to a study from the December issue of Anesthesiology. Researchers found that inhaled nitric oxide reduced tissue injury and improved short-term survival in mice that were resuscitated with a stored blood transfusion after hemorrhagic shock.

Study demonstrates memory-enhancing effects of low-level light therapy

It's called the "Silver Tsunami" - the swelling number of baby boomers surpassing age 65. As medical advancements extend their lives, they're expected to live well into their 80s and 90s - outlasting any generation in American history.
