FAQs: NSF Division of Molecular and Cellular Biosciences (MCB) Core Programs (NSF 24-539)

What is the NSF MCB Core Programs opportunity?

The NSF Division of Molecular and Cellular Biosciences (MCB) Core Programs is a grant opportunity that supports basic, discovery-driven research aimed at revealing how living systems work at the atomic, molecular, subcellular, and cellular levels. The program emphasizes mechanistic understanding of biological structure, function, and evolution.

What types of research does MCB prioritize?

MCB prioritizes projects that move beyond descriptive findings and toward quantitative, predictive understanding of complex biological behaviors and emergent properties. The strongest alignment is with research that delivers mechanistic insight and clarifies general principles of molecular and cellular life.

Is this program focused on basic research or applied research?

This program is designed for basic, fundamental research. While NSF recognizes that basic molecular and cellular research can lead to downstream impacts (for example in health, environment, energy, or food), the MCB Core Programs are not designed to fund projects that are narrowly centered on applied outcomes such as treatments for human disease.

Does MCB support higher-risk or potentially transformative ideas?

Yes. The opportunity explicitly welcomes innovative ideas, including potentially transformative and higher-risk approaches, as long as they are grounded in advancing fundamental molecular and cellular biology.

What does MCB mean by "mechanistic insight"?

Based on the opportunity description, "mechanistic insight" refers to explaining how and why biological systems work the way they do (structure, dynamics, function, and evolution), rather than only documenting what is observed. The program preference is for work that enables more quantitative and predictive understanding.

Does MCB encourage interdisciplinary or cross-disciplinary research?

Yes. A defining feature of MCB is its encouragement of cross-disciplinary thinking and toolsets. Proposals are expected to benefit from, or be strengthened by, approaches from disciplines such as chemistry, computer science, engineering, mathematics, and physics, particularly where these approaches help identify general principles at molecular and cellular scales.

Are computational, mathematical, and theoretical approaches encouraged?

Yes. MCB values the integration of experimental and theoretical work, including computational and mathematical modeling. Proposals that pair experiments with computation or theory are highlighted as a program priority across clusters.

Does MCB support research across different organisms, including non-model systems?

Yes. The program supports research using a wide variety of organisms and encourages investigators to draw from classic model systems as well as diverse non-model animals, plants, and microbes, reflecting an interest in broad biological principles across the tree of life.

How is the MCB Core Programs portfolio organized?

The solicitation organizes supported research into four core clusters: Molecular Biophysics; Genetic Mechanisms; Cellular Dynamics and Function; and Systems and Synthetic Biology.

What topics fit within the Molecular Biophysics cluster?

The Molecular Biophysics cluster covers the structure, dynamics, and function of biomolecules and larger biological assemblies. A specific emphasis is understanding these processes under physiological conditions rather than only in simplified or artificial settings.

What topics fit within the Genetic Mechanisms cluster?

The Genetic Mechanisms cluster supports research on how genetic and epigenetic information is organized, processed, expressed, regulated, and evolves.

What topics fit within the Cellular Dynamics and Function cluster?

The Cellular Dynamics and Function cluster focuses on how cellular structures and properties drive function across spatial and temporal scales, ranging from local molecular events to whole-cell behaviors.

What topics fit within the Systems and Synthetic Biology cluster?

The Systems and Synthetic Biology cluster supports studies of complex molecular-to-cellular interactions through modeling, manipulation, or the design of biological systems. This includes synthetic approaches that test biological principles by building or rewiring biological systems.

Do proposals need to fit neatly into one cluster?

No. Work that sits at the boundaries between clusters is explicitly welcomed. Bridging areas can be viewed as a strength when it leads to deeper, more general insight.

What cross-cutting priorities apply across all clusters?

Across the clusters, MCB places priority on projects that integrate across scales, investigate molecular and cellular evolution, pair experiments with computation or theory, and/or develop broadly useful methods and technologies.

What is the Integrative Research in Biology (IntBIO) track and how does it relate to MCB?

The opportunity notes that projects connecting molecular and cellular biosciences with other biological subdisciplines can be supported through the Integrative Research in Biology (IntBIO) track. This indicates that proposals can be positioned to bridge MCB with other areas of biology when doing so advances integrative understanding.

Are human disease-focused proposals eligible under MCB?

Projects focused exclusively on understanding or treating human disease are typically considered out of scope for MCB and may be returned without review. An exception is noted when the work also makes a clear, significant advance in other fields such as engineering, computer science, mathematics, or the physical sciences, consistent with NSF's basic research mission.

Will MCB fund research that has potential health, environmental, energy, or food impacts?

NSF recognizes that basic molecular and cellular research often has downstream impacts in areas like human health, environmental solutions, energy, and food production. However, the program description emphasizes that MCB is not designed to fund projects that are narrowly centered on applications like disease mechanisms or treatments.

Who is eligible to submit a proposal?

Eligibility to submit is limited to certain U.S.-based organizations. Eligible applicants include U.S. institutions of higher education (two- or four-year, including community colleges) that are accredited and have a U.S. campus, submitting on behalf of faculty. Eligible applicants also include U.S.-based non-profit, non-academic organizations (such as independent museums, observatories, research laboratories, and professional societies) as long as they are directly associated with educational or research activities.

Can a non-academic non-profit apply?

Yes, if it is a U.S.-based non-profit, non-academic organization (for example, an independent museum, observatory, research laboratory, or professional society) and it is directly associated with educational or research activities.

Do community colleges qualify as eligible institutions?

Yes. The opportunity states that U.S. institutions of higher education can be two- or four-year institutions, including community colleges, provided they are accredited and have a U.S. campus.

Are international branch campuses or international project activities allowed?

If a proposal involves funding going to an international branch campus of a U.S. institution (including through subawards or consultants), the submission must clearly explain why work at the international site benefits the project and why those activities cannot be carried out at the U.S. campus.

What is the funding opportunity number and CFDA listing for this program?

The opportunity is identified as NSF Funding Opportunity Number 24-539 with CFDA 47.074.

What grant category is this opportunity listed under?

In the source listing, this opportunity is categorized as a discretionary grant for science and technology research and development.

When was this opportunity posted?

The posting date shown in the source listing is February 14, 2024.

Is there a deadline to apply?

The listing shows an original closing date far in the future. This generally signals an ongoing or standing solicitation rather than a one-time deadline. Applicants are still expected to confirm current submission windows and program guidance in the official NSF solicitation materials.

Is there an award ceiling or a stated number of expected awards?

No. The provided source data does not specify an award ceiling or the expected number of awards.

What kind of projects are most likely to be considered a good fit overall?

Based on the description provided, strong-fit projects are those that advance fundamental molecular and cellular biology through mechanistic, discovery-driven research; lean toward quantitative and predictive understanding; incorporate cross-disciplinary tools where useful; and often integrate experiments with computation or theory, potentially spanning scales, evolution, and/or broadly useful methods.
