Open Molecular Biology Grants and Fellowships: July 2026 Deadline Radar

The near-term deadline stack is heavy: travel and short-stay fellowships hit first, then the large postdoc cycles open up in August and September. If you are a molecular biology PhD student or postdoc, the fastest wins this fortnight are the programs where your PI or host lab can already confirm fit and write support letters without rebuilding the project from scratch.

Deadline Radar

Deadline	Opportunity	Best fit	First action
August 7, 2026	The Company of Biologists Travelling Fellowships	Graduate students and postdocs planning a collaborative lab visit in areas covered by Development, Journal of Cell Science, or Journal of Experimental Biology. Awards are up to £3,000, and travel for this round must be after September 21, 2026. 1	Confirm the visit has not already started, then collect the supervisor, host-lab, and department letters.
August 8, 2026	NIH NRSA Individual Predoctoral Fellowship, Parent F31 (PA-25-422)	U.S.-based predoctoral researchers proposing mentored biomedical research relevant to participating NIH institutes, including NIGMS participation added in 2026. Applications are due by 5:00 pm local time of the applicant organization. 2	Check the institute-specific contact table before writing aims; the participating institute matters as much as the general F31 mechanism.
August 8, 2026	NIH NRSA Individual Postdoctoral Fellowship, Parent F32 (PA-25-423)	Postdocs seeking mentored biomedical training aligned with a participating NIH institute. The next listed due date is August 8, 2026, at 5:00 pm local time of the applicant organization. 3	Ask your sponsor to help frame the training gap, not just the project; the F32 is reviewed as a training plan.
August 14, 2026, 20:00 UTC	Damon Runyon Fellowship Award	New cancer researchers, including molecular approaches to cancer mechanisms and prevention. Applications are due at 4:00 pm Eastern Time, and basic-science applicants generally must be early in postdoctoral training. 4	Decide quickly whether your project is a real departure from your PhD work; direct extensions are explicitly disfavored.
August 14, 2026 expression of interest; September 30, 2026 full application	ICGEB Arturo Falaschi Fellowships, including PhD, postdoctoral, short-term, and SMART mobility tracks	Life-science researchers connected to ICGEB Member States, especially those seeking work in ICGEB labs or South-South research mobility. 5	Treat the August expression of interest as the real gate; the full application comes only after that first step.
September 2, 2026, 03:59 UTC	CRI Irvington Postdoctoral Fellowship	Postdocs in fundamental immunology or tumor immunology, including mechanistic molecular immunology relevant to cancer. CRI lists the September 1 deadline as 11:59 pm Eastern Time. 6	Make the cancer-immunology relevance explicit in the project summary; a strong molecular mechanism still has to answer the immune-system fit test.
September 9, 2026	MSCA Postdoctoral Fellowships 2026	Postdoctoral researchers with a PhD and up to eight years of research experience after the PhD, applying with a host organization for European or Global Fellowships. The 2026 call has a €399.05 million budget and is expected to fund nearly 1,600 projects. 7	Start with mobility eligibility and host commitment; a good proposal will not survive a wrong host-country setup.
September 16, 2026, 07:59 UTC	IUBMB Travel Fellowships	Biochemistry and molecular biology PhD students or junior researchers within five years of the PhD who will present a poster or talk at an international meeting in the IUBMB region. The source states quarterly deadlines of March 15, June 15, September 15, and December 15 at 11:59 pm Pacific Standard Time. 8	Verify that your national society is a full or associate IUBMB member before spending time on the form.
Rolling: apply any time	FEBS Short-Term Fellowships and Ukrainian Short-Term Fellowships	Molecular life scientists in the FEBS area seeking a research stay in a lab in another FEBS country; short-term fellowships cover PhD students with at least one first-author paper and recent PhDs. 9	Use this as a rolling option for technique transfer or a focused collaboration rather than a full postdoc funding plan.

What I Would Prioritize This Week

If your deadline tolerance is low, start with the Company of Biologists and NIH F31/F32 calls. They are close enough that a realistic application depends on existing pieces: a defined host or sponsor, a project that already has an aims page, and letters that can be requested immediately.

If you are a postdoc with an international move in mind, the MSCA and ICGEB tracks deserve early attention because eligibility is not just about science. Host country, mobility history, Member State status, and sponsor commitment can decide fit before reviewers ever read the molecular biology.

For cancer-adjacent molecular biology, Damon Runyon and CRI Irvington are both attractive, but they are not interchangeable. Damon Runyon can fit broad cancer mechanisms, while CRI Irvington is anchored in immunology and cancer immunology. If your proposal is mainly cell-cycle control, DNA repair, epigenetics, or RNA biology, you need to explain the cancer or immune relevance without making it look bolted on.

One Near-Open Call To Put On Your Calendar

The Life Sciences Research Foundation cycle is not open today: its page says the grant cycle will open on August 15, 2026, with an October 1, 2026 application deadline at 8:00 pm Eastern Time. That is worth a reminder, but it does not belong in the open-call table yet. 10

Quick Screen Before You Apply

Stage fit: Predoc, early postdoc, established postdoc, and junior PI calls use different evidence of readiness. Do not stretch a CV into the wrong stage.
Field fit: Broad biomedical calls can support molecular biology, but foundation calls often want a sharper disease, immunology, mobility, or training angle.
Letter burden: Anything due in August should be treated as urgent if it requires host, sponsor, department, or reference letters.
Institutional routing: NIH deadlines are local to the applicant organization, and many universities set internal deadlines days or weeks earlier.
Project portability: Travel and mobility fellowships reward a clearly bounded experiment or skill transfer. A vague “collaboration” is usually weaker than a specific method, dataset, or reagent exchange.
