Grand Challenges for Biological and Environmental Research
A Long-Term Vision for Solving Our Planet's Most Pressing Scientific Puzzles
Our Planet's Most Pressing Scientific Puzzles
In an era of rapid climate change, unprecedented biodiversity loss, and complex environmental threats, scientists are confronting what they term "Grand Challenges"—critical knowledge gaps that constrain our ability to make informed decisions for the well-being of both people and the planet . These are not ordinary scientific questions but rather complex, interconnected puzzles that span disciplines and scales, from the molecular mechanisms within a single cell to the global systems that sustain life on Earth.
The solutions to these challenges hold the key to everything from preventing future pandemics and curbing climate change to ensuring food security for a growing global population.
What makes these questions particularly compelling—and difficult—is their inherent complexity. Unlike traditional scientific inquiries that can be isolated in laboratory settings, Grand Challenges require collaboration across disciplines, merging insights from biology, climate science, data analytics, social sciences, and ethics. Researchers are no longer simply trying to understand how one element functions in isolation, but rather how countless elements interact within dynamic, ever-changing systems.

In-Depth Look: Tracing Air Pollution's Path to Lung Cancer
To illustrate how Grand Challenges research unfolds in practice, let's examine a specific, crucial experiment currently underway in Chennai, India. Dr. Vijayalakshmi Ramshankar and her team at the Cancer Institute (WIA) are conducting a groundbreaking study investigating the impact of air pollution on non-smoking-associated lung cancer 3 .
This research addresses the critical Grand Challenge of understanding how environmental factors drive disease, particularly in populations without traditional risk factors.
Methodology: A Step-by-Step Approach
Participant Recruitment
The team is recruiting non-smoking lung cancer patients from Chennai, intentionally focusing on this population to isolate the effects of air pollution from the confounding factor of tobacco use 3 .
Genetic Screening
All participating patients are screened for EGFR driver mutations, which are known to promote air pollution-related lung cancer, providing a molecular link between exposure and disease 3 .
Biological Sampling
Researchers perform periodic blood sampling of patients to measure cytokine and miRNA profiles, which can serve as biomarkers of immune response and gene regulation changes associated with air pollution exposure 3 .
Household Monitoring
The study extends to patients' asymptomatic household family members, who undergo the same blood analysis and are offered further testing (low-dose spiral CT scanning) for early cancer detection 3 .
Environmental Assessment
The team deploys air pollution monitoring devices in participants' households to continuously track indoor exposure, creating a detailed record of pollution levels correlated with biological markers 3 .
Integrated Data Analysis
Finally, researchers perform statistical analysis combining the biological and environmental data to better understand how air pollution affects lung cancer risk and to identify a high-risk signature that could guide early screening efforts 3 .
