Study of How Genes Activate Yields Surprising Discovery
Albert Einstein College of Medicine

Scientists at Albert Einstein College of Medicine of Yeshiva University have made an unexpected finding about the method by which certain genes are activated. Contrary to what researchers have traditionally assumed, genes that work with other genes to build protein structures do not act in a coordinated way but instead are turned on randomly. The surprising discovery, described in the December 5 online edition of Nature Structural and Molecular Biology, may fundamentally change the way scientists think about the way cellular processes are synchronized.

Gene-Environment Interactions Could Influence Several Psychiatric Disorders
Johns Hopkins Medicine

Male mice born with a genetic mutation that’s believed to make humans more susceptible to schizophrenia develop behaviors that mimic other major psychiatric illnesses when their mothers are exposed to an assault to the immune system while pregnant, according to new Johns Hopkins research.

The Gene-Environment Enigma
Washington University in St. Louis

Personalized medicine centers on being able to predict the risk of disease or response to a drug based on a person’s genetic makeup. But a study by scientists at Washington University School of Medicine in St. Louis suggests that, for most common diseases, genes alone only tell part of the story. Their research shows the environment interacts with DNA in ways that are difficult to predict, even in simple organisms like single-celled yeast.

Team Identifies a Genetic Switch for Determining Gender
NYU Langone Health

An international team has identified a gene that appears to be an important switch in determining whether the biological program for the development of gender will go according to plan, or if, when mutated, will cause a glitch in the program.

Gene Duplication Detected in Depression
Children's Hospital of Philadelphia

A large genetic study of people with major depression has found that a duplicated region of DNA on chromosome 5 predisposes people to the disorder. The gene at that site influences nerve cell development.

New Study Suggests That a Propensity for One-Night Stands, Uncommitted Sex Could be Genetic
Binghamton University, State University of New York

So, he or she has cheated on you for the umpteenth time and their only excuse is: “I just can’t help it.” According to researchers at Binghamton University, they may be right. The propensity for infidelity could very well be in their DNA.

Genomic Fault Zones Come and Go
University of California San Diego

The fragile regions in mammalian genomes that are thought to play a key role in evolution go through a "birth and death" process, according to new bioinformatics research performed at the University of California, San Diego. The new work, published in the journal Genome Biology on November 30, could help researchers identify the current fragile regions in the human genome – information that may reveal how the human genome will evolve in the future.

Researchers Re-sequence Six Corn Varieties, Find Some Genes Missing
Iowa State University

Researchers at Iowa State University, China Agricultural University and the Beijing Genomics Institute in China recently re-sequenced and compared six elite inbred corn (maize) lines, including the parents of the most productive commercial hybrids in China and found entire genes that were missing from one line to another.

Researchers Kick-Start Ancient DNA
Binghamton University, State University of New York

Binghamton University researchers recently revived ancient bacteria trapped for thousands of years in water droplets embedded in salt crystals. For decades, geologists have looked at these water droplets — called fluid inclusions — and wondered whether microbes could be extracted from them. Fluid inclusions have been found inside salt crystals ranging in age from thousands to hundreds of millions years old.
