Prolonged exposure to particulate matter in air pollution in the Los Angeles Basin triggered inflammation and the appearance of cancer-related genes in the brains of rats, a study has found.

Dietary fiber increases survival in influenza-infected mice by setting the immune system at a healthy level of responsiveness, according to a preclinical study. A high-fiber diet blunts harmful, excessive immune responses in the lungs while boosting antiviral immunity by activating T cells.

Enzymes made by microorganisms living in the Amazon could be the key to increasing production of ethanol fuel in the world's biggest ethanol producer, Brazil.

Researchers have decoded the epigenetic landscape for rheumatoid arthritis (RA), In unveiling RA’s epigenome scientists made a surprising discovery: an overlap between the causes of RA and Huntington’s disease, a fatal and incurable genetic brain disease.

Alpha-linolenic acid (ALA) and linoleic acid (LA) are plant-based essential fats—called polyunsaturated fatty acids (PUFA)—that humans consume through diet. A new study has shown how regular consumption of these fats controls gene expression in skeletal muscle.

For the past several decades, scientists have been trying to determine how these nucleosome roadblocks clear out to allow genes to be turned on. Now, a new study has identified a key factor that partially unravels nucleosomes and clears the way for genes to activate.

APOE4 is a gene variant linked to a higher risk of Alzheimer's Disease. A study exploring the link between traumatic brain injury (TBI) and psychiatric disorders has suggested that APOE4 increases the risk of Post-Traumatic Stress Disorder in TBI patients.

An international team has developed a novel tool to accurately predict eye, hair and skin color from human biological material -- even a small DNA sample -- left, for example, at a crime scene or obtained from archeological remains. This provides a physical description of the person in a way that has not previously been possible.

A team of scientists has found that in the colorectal tumors they examined, invasive cancers are born to be bad, and this tendency can potentially be identified at early diagnosis.

E. coli is a bacterium which can cause severe food poisoning. A strain of E. coli resistant to the "last resort" antibiotic colistin has been found in a chinese poultry farm, highlighting the risk of a possible "post-antibiotic" era.
