Professor Antonis Rokas, finalist for the Blavatnik National Award for Young Scientists

Antonis Rokas is one of 30 finalists picked from a pool of the most promising scientific researchers aged 42 years and younger at America’s top academic and research institutions. From this group “national laureates” will be chosen in three fields: physical sciences and engineering, life sciences, and chemistry. The final selection will be announced in late June and the research of the 2017 finalists and honorees from previous years will be featured at a symposium in July in New York City. The Blavatnik Awards were established in 2007 by the Blavatnik Family Foundation and are administered by the New York Academy of Sciences to recognize exceptional young researchers who will drive the next generation of innovation by answering today’s most complex and intriguing scientific questions. Rokas studies the DNA record to gain insight into the patterns and processes of evolution using both computational and experimental approaches. He is particularly interested in three major questions: How did human pregnancy evolve? What are the molecular foundations of the fungal lifestyle? How can we elucidate the tree of life?

New method for tapping vast plant pharmacopeia to make more effective drugs - Rokas Lab

Cocaine, nicotine, capsaicin. These are just three familiar examples of the hundreds of thousands of small molecules (also called specialized or secondary metabolites) that plants use as chemical ammunition to protect themselves from predation. Unfortunately, identifying the networks of genes that plants use to make these biologically active compounds, which are the source of many of the drugs that people use and abuse daily, has vexed scientists for years, hindering efforts to tap this vast pharmacopeia to produce new and improved therapeutics. Now, Vanderbilt University geneticists think they have come up with an effective and powerful new way for identifying these elusive gene networks, which typically consist of a handful to dozens of different genes, that may overcome this road block.

Forget sponges: the earliest animals were marine jellies - Rokas Lab

For the last decade, zoologists have been battling over the question, “What was the oldest branch of the animal family tree?” Was it the sponges, as they had long thought, or was it a distinctly different set of creatures, the delicate marine predators called comb jellies? The answer to this question could have a major impact on scientists’ thinking about how the nervous system, digestive tract, and other basic organs in modern animals evolved.

New tool for combating mosquito-borne disease: insect parasite genes

The Bordenstein Lab together with researchers from Yale have identified the specific genes that allow the bacteria Wolbachia to hijack a host insect’s reproductive system. This discovery will potentially help researchers develop methods for controlling insect-borne diseases like dengue and Zika viruses.

What Did Neanderthals Leave to Modern Humans? Some Surprises.

Geneticists tell us that somewhere between 1 and 5 percent of the genome of modern Europeans and Asians consists of DNA inherited from Neanderthals, our prehistoric cousins. At Vanderbilt University, John Anthony Capra, an evolutionary genomics professor, has been combining high-powered computation and a medical records databank to learn what a Neanderthal heritage — even a fractional one — might mean for people today.

Each animal species hosts a unique microbial community and benefits from it

Each animal species hosts its own, unique community of microbes that can significantly improve its health and fitness. That is the implication of a laboratory study that investigated four different animal groups and their associated microbiota. The research found that each species within the group has a distinctive microbial community. “Previous research has tended to concentrate on the negative effects of microbes. In this case we are showing that whole communities of microbes have positive effects as well,” said Vanderbilt graduate student Andrew Brooks, co-first author of the study.

Steve Baskauf and Vanderbilt's Bicentennial Oak

From the October 19th issue of MyVU: Vanderbilt University’s Bicentennial Oak has been recognized as a Landmark Tree by the Tennessee Urban Forestry Council. The designation is given to Tennessee trees that are “commonly recognized as an established and familiar feature of the community or can be confirmed as a significant part of the community’s heritage.” The Bicentennial Oak is the only tree on the Vanderbilt campus known to predate the university.

Suzana Herculano-Houzel examines the evolution of the brain

In News@Vanderbilt (Oct. 17, 2016) Suzana Herculano-Houzel examines the question, “What is different about humans that allowed them to evolve brains with so many neurons, which large apes can’t afford?”
