(a) Biological systems
The Director shall carry out research and development activities in fundamental, structural, computational, and systems biology to increase systems-level understanding of the complex biological systems, which may include activities—

(1) to accelerate breakthroughs and new knowledge that would enable the cost-effective, sustainable production of—

(A) biomass-based liquid transportation fuels;

(B) bioenergy; and

(C) biobased materials;

(2) to improve understanding of the global carbon cycle, including processes for removing carbon dioxide from the atmosphere, through photosynthesis and other biological processes, for sequestration and storage; and

(3) to understand the biological mechanisms used to transform, immobilize, or remove contaminants from subsurface environments.

(b) Limitation for research funds
The Director shall not approve new climate science-related initiatives without making a determination that such work is well-coordinated with any relevant work carried out by other Federal agencies.

(c) Low-dose radiation research program

(1) In general
The Director shall carry out a research program on low-dose radiation.

(2) Purpose
The purpose of the program is to enhance the scientific understanding of, and reduce uncertainties associated with, the effects of exposure to low-dose radiation to inform improved risk-management methods.
