Science has always fascinated Anshul Kundaje, whether it was biology, physics, or chemistry. When he left his home country of India to pursue graduate studies in electrical engineering at Columbia University, New York, his plan was to focus on telecommunications and computer networks. But a course in computational genomics during his first semester showed him he could follow his interest in computing without giving up his love for biology.

Now an assistant professor of genetics and computer science at Stanford University, Palo Alto, CA, Kundaje has received a 2016 NIH Director’s New Innovator Award to explore not just how the human genome sequence encodes function, but also why it functions in the way that it does. Kundaje even envisions a time when it might be possible to use sophisticated computational approaches to predict the genomic basis of many human diseases.


Creative Minds: Exploring the Role of Immunity in Hypertension

If Meena Madhur is correct, people with hypertension will one day pay as much attention to their immune cell profiles as their blood pressure readings. A physician-researcher at Vanderbilt University School of Medicine, Nashville, Madhur is one of a growing number of scientists who thinks the immune system contributes to—or perhaps even triggers—hypertension, which increases the risk of stroke, heart disease, kidney disease, and other serious health problems.

About one of every three adult Americans currently have hypertension, yet a surprising number don’t know they have it and less than half have their high blood pressure under control—leading many health experts to refer to the condition as a “silent killer”[1,2]. For many folks, blood pressure control can be achieved through lifestyle changes, such as losing weight, exercising, limiting salt intake, and taking blood pressure medicines prescribed by their health-care provider. Unfortunately, such measures don’t work for everyone, and some people continue to suffer damage to their kidneys and blood vessels from poorly controlled hypertension.

Madhur wants to know whether the immune system might be playing a role, and whether this might hold some clues for developing new, more targeted ways of treating high blood pressure. To get such answers, this practicing cardiologist will use her 2016 NIH Director’s New Innovator Award to conduct sophisticated, single-cell analyses of the immune systems of people with and without hypertension. Her goal is to produce the most comprehensive catalog to date of which human immune cells might be involved in hypertension.


Creative Minds: Reprogramming the Brain

When most people think of reprogramming something, they probably think of writing code for a computer or typing commands into their smartphone. Melanie Samuel thinks of brain circuits, the networks of interconnected neurons that allow different parts of the brain to work together in processing information.

Samuel, a researcher at Baylor College of Medicine, Houston, wants to learn to reprogram the connections, or synapses, of brain circuits that function less well in aging and disease and limit our memory and ability to learn. She has received a 2016 NIH Director’s New Innovator Award to decipher the molecular cues that encourage the repair of damaged synapses or enable neurons to form new connections with other neurons. Because extensive synapse loss is central to most degenerative brain diseases, Samuel’s reprogramming efforts could help point the way to preventing or correcting wiring defects before they advance to serious and potentially irreversible cognitive problems.


Creative Minds: Rapid Testing for Antibiotic Resistance

The term “freeze-dried” may bring to mind those handy MREs (Meals Ready to Eat) consumed by legions of soldiers, astronauts, and outdoor adventurers. But if one young innovator has his way, a test that features freeze-dried biosensors may soon be a key ally in our nation’s ongoing campaign against the very serious threat of antibiotic-resistant bacterial infections.

Each year, antibiotic-resistant infections account for more than 23,000 deaths in the United States. To help tackle this challenge, Ahmad (Mo) Khalil, a researcher at Boston University, recently received an NIH Director’s New Innovator Award to develop a system that can more quickly determine whether a patient’s bacterial infection will respond best to antibiotic X or antibiotic Y—or, if the infection is actually viral rather than bacterial, no antibiotics are needed at all.
