Interior announces new partnership to advance conservation of imperiled species through biobanking and genomic science. Department of the Interior announces new partnership to advance conservation of imperiled species through biobanking and genomic science. Partnership between the U.S. Fish and Wildlife Service and Colossal Biosciences will support innovative conservation tools for threatened and endangered species Jun 25, 2026 Media Contacts WASHINGTON - The Department of the Interior today announced a Memorandum of Understanding between the U.S. Fish and Wildlife Service and Colossal Biosciences to advance the use of biobanking and genomic science in support of wildlife conservation and species recovery efforts. This cooperative effort advances President Donald J. Trump's broader efforts to promote American innovation, leverage public-private partnerships, and ensure that conservation programs are informed by the best available science and technology. The agreement establishes a framework for partnership focused on preserving genetic diversity among threatened and endangered species, expanding scientific understanding of genomic applications in conservation, and exploring emerging technologies that may strengthen recovery efforts for species at risk. "America leads the world when we embrace innovation and put our best minds to work solving big challenges," said Secretary of the Interior Doug Burgum. "This partnership brings together the scientific expertise of the U.S. Fish and Wildlife Service and the ingenuity of the private sector to develop new tools that can help recover species, preserve critical genetic resources, and strengthen the future of wildlife conservation." Biobanking involves the collection and long-term cryopreservation of living biological materials, including tissues and cell lines that contain genetic information. Preserving these materials can support future conservation research, population management efforts and other scientific applications as technologies continue to evolve. Under the agreement, the Service and Colossal Biosciences will work together to identify opportunities to expand biobanking efforts for species of conservation concern, develop approaches for integrating genomic information into conservation planning, establish best practices for data management and accessibility, and support training and capacity-building initiatives related to conservation genomics. "As biodiversity faces increasing pressures worldwide, we must continue to evaluate and apply the best available science to conserve America's natural heritage," said U.S. Fish and Wildlife Service Director Brian Nesvik. "Our work with Colossal Biosciences will help advance our understanding of how biobanking and genomics can complement existing conservation tools and contribute to the recovery and long-term resilience of imperiled species." The partnership will also facilitate scientific exchange and help identify priority species and conservation needs where biobanking may provide meaningful benefits to recovery and management efforts. The Memorandum of Understanding reflects a shared commitment to conservation science and does not obligate the expenditure of federal funds. Any future projects involving funding, services, or property transfers would be subject to separate agreements and applicable legal requirements. The U.S. Fish and Wildlife Service works with partners across the nation and around the world to conserve, protect and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people. Through science-based conservation, habitat restoration, and recovery programs, the Service helps safeguard biodiversity and strengthen ecosystems for future generations. Published.

Colossal Biosciences innovates with 3d-printed eggs. Colossal Biosciences has made headlines by developing an innovative 3D-printed artificial eggshell, designed to cultivate living chicks outside of traditional eggs. This breakthrough occurred at the company's Dallas headquarters, where researchers observed baby chicks moving and attempting to hatch from transparent plastic constructs rather than organic eggs. The artificial eggshell, more accurately described as a synthetic incubation system, is an oval-shaped lattice coated with a specialized silicone membrane that allows oxygen to permeate, mimicking the natural function of an eggshell. In a unique process, Colossal poured the contents of recently laid chicken eggs into these artificial shells, allowing the embryos to develop under controlled conditions. The transparent design features a viewing window that enables scientists to monitor the chicks' growth. Andrew Pask, the company's Chief Biology Officer, expressed excitement at witnessing life develop outside the womb, emphasizing the potential of this technology not only for avian conservation but also in efforts to resurrect extinct species like the giant moa and the dodo. Colossal's aim is to utilize gene-editing technologies to create animals with desired traits, having already raised substantial funding towards this mission. While the artificial eggshell represents a significant step forward, some experts in the scientific community have raised concerns about the claims surrounding its novelty. Critics argue that the principles behind the technology are not entirely new, referencing previous work in artificial incubation by other researchers. The discussion highlights a broader conversation about the challenges of cross-species genetic manipulation, especially when it comes to larger extinct birds like the moa. As Colossal endeavors to push the boundaries of biotechnology, the collaboration and scrutiny from the scientific community will be critical in navigating the ethical implications and technical hurdles that lie ahead.
Colossal Biosciences, a Texas company working to revive extinct species, has successfully hatched healthy chickens using artificial eggs, marking progress towards resurrecting the dodo and giant moa. The company announced on Tuesday that more than two dozen chicks have been born from its 3D-printed plastic eggs. The artificial eggs replicate natural egg functions and will be scaled up for larger extinct birds. Colossal plans to create dodo and moa embryos using gene-edited cells from the Nicobar pigeon and emu, respectively. Whilst some scientists praise the technology's conservation potential, critics question the ethics and feasibility of de-extinction. They argue the animals may be doomed without suitable habitats and could damage existing ecosystems. Colossal has raised $295 million to date and is also developing artificial wombs for mammals like the woolly mammoth.
A second startup from Dallas billionaire Ben Lamm has achieved unicorn status with a $2 billion valuation in its latest funding round. Lamm, who also co-founded and leads Colossal Biosciences, has seen his new venture reach the milestone valuation. The company focuses on predicting biology, evolution and diseases before they occur. This marks Lamm's second startup to surpass the $1 billion valuation threshold, following his success with Colossal Biosciences.
Colossal Biosciences, which is trying to bring back the wooly mammoth with genetics tech, has spun out its AI startup Astromech at a $2 billion valuation.
