Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

Epigenetics is the study of various heritable alterations that control gene expression without changing the DNA sequence. 1 The name epigenetics comes from the Greek prefix “epi”, which means on top ...

A collaborative effort has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...

Our brain is arguably the organ that most distinguishes humans from other primates. Its exceptional size, complexity and capabilities far exceed those of any other species on Earth. Yet humans share ...

Using genomic and transcriptional data has greatly improved the understanding of multiple aspects of human physiology. A new paper in PNAS reports on molecular-level associations of co-occurring ...

Researchers have unveiled a way to flip genes back on without slicing into the genome, a shift that could make CRISPR far ...

A revolutionary gene-silencing technique has shown that a single treatment can dramatically lower LDL cholesterol levels for over a year—without permanently altering DNA. Could this be the future of ...

Genetics is the study of genes and how they influence characteristics and health. Through a variety of technological methods, environmental factors, and lifestyle choices, it is possible to alter some ...

Plant scientists have used a standard "gene gun" since 1988 to genetically modify crops for better yield, nutrition, pest resistance and other valuable traits. Subscribe to our newsletter for the ...
