CETI is a nonprofit org applying advanced machine learning and gentle robotics to listen to and translate whale communication. 

Founded in 2020 as a TED Audacious Project, the organization’s science team is made up of the world's leading artificial intelligence and natural language processing experts, marine biologists, cryptographers, linguists, roboticists and underwater acousticians. CETI’s research is taking place off of the island of Dominica in the Caribbean.

In the late 1960s, scientists, including Dr. Roger Payne, a principal advisor of CETI, discovered that whales sing to one another. His recordings, Songs of the Humpback Whale, sparked the “Save the Whales” movement, one of the most successful conservation initiatives in history. The campaign eventually led to the Marine Mammal Protection Act that marked the end of large-scale whaling and saved several whale populations from extinction. 

All this by just hearing the sounds of whales. Imagine what would happen if we could understand them?

WHY WHALES 
Sperm whales specifically share traits strikingly similar to humans. They live in matriarchal and multicultural societies and share dialects and strong multigenerational family bonds. Sperm whales have the largest brains of any species and have higher-level functions such as conscious thought and future planning, as well as speech and feelings of compassion, love, suffering and intuition. Their vocalizations, among the loudest animal sounds on the planet, have a Morse code-like structure that shares the hallmarks of a highly-evolved language. Our understanding of these animals and their dialects is still in its infancy. Only in the last fifteen years have we begun to learn how some of their vocalizations are used for communication.  
WHAT CETI IS DOING
CETI is:
-Developing non-invasive robotics to listen to a population of whales in the Caribbean and put their sounds into context.
-Deploying a “Core Whale Listening System,” an innovative hydrophone array, underwater robotic gliders, custom bioinspired whale tags and other technology to gently study the whales.
-Building on substantial data on the whales’ sounds, social lives, and behavior already obtained by the Dominica Sperm Whale Project. 
-Creating a bespoke, big-data pipeline to examine the recorded data and decode it using advanced machine learning, natural language processing and data science.
-Publishing a series of academic papers beginning with the CETI roadmap.
-Collaborating with the National Geographic Society, including their Exploration Technology Lab, and amplifying the project across National Geographic’s storytelling and education channels.
-Implementing community-based programs like the Dominica Marine Conservation Fellowship, a community-based 10-month multi- module training program for young Dominicans interested in marine science, that was developed in partnership with National Geographic.
-Launching various communications projects to tell CETI’s story including a public interface for the citizen science community, resources for educators and children and arts programs.

IMPACT
Now, for the first time in history, it’s possible to use artificial intelligence to identify and interpret deep structure within animal communication. Using these technologies, CETI is building on the legacy of the “Save the Whales” movement with the goal of having an impact by contributing the following:
Interspecies Communication - A new data set of unprecedented size to the rapidly expanding field of interspecies communication and a roadmap of how humans could translate the communication of any other species
Marine Biology - A substantive contribution to the field of whale research within marine biology that opens gateways for future research initiatives. 
Policy - New information about whales that can bolster policy efforts to protect marine mammals and ocean habitats. Policy advances in this area are crucial as six out of the 13 “great” whale species (the largest whales) are still endangered (World Wildlife Federation). To ensure impact in this area, CETI plans to build out policy campaigns and initiatives. 
Perspective - It is widely endorsed that connectivity with nature can improve mental health. By sharing its journey and findings with the public, CETI hopes to contribute to a feeling of increased wonder and connectedness to whales and the ocean that can inspire action. CETI will build out arts and childrens’ initiatives in support of this impact goal.
Conservation - CETI’s first phase of research is taking place in Dominica in the Caribbean, a region that is one of the world’s greatest centers of diversity. By carrying out its research in partnership with local stakeholders, CETI hopes to contribute to regionally-led research and conservation efforts.

HOW CETI IS SUPPORTING DOMINICA
-CETI’s capacity-building initiative, Dominica Marine Conservation Fellowship is a 10-month, nine module training program for young Dominicans interested in marine science) in partnership with National Geographic.  The program has three 2022/2023 fellows and partnerships with the Dominica National Youth Council, Dominica State College and Dominica’s Ministry of Education. The program’s curriculum (co-created with National Geographic) includes modules on marine science, scientific research/techniques, water and vessel skills and storytelling and leadership among other topics.
-All research and findings by CETI in Dominica are all open-source and will be available for Dominica. The organization’s sailing research vessel (CETI-1), a Rigid Inflatable Boat (CETI-2) and Dominican made boat (CETI-3) are in operation in Dominican waters; these boats along with other CETI equipment will be donated to the local entity at the completion of the project.
-A temporary field station has been established in Dominica and has the capacity to host 10-12 researchers, fellows and students. In the long-term, CETI plans to build a permanent field station in Dominica 
-In 2023, CETI will continue local engagement and presentations with primary and secondary schools, development of video content for use in classrooms, collaborations with local artists and collaborations with local stakeholders such as marine and dive operators, civil society organizations and schools.

Rescuing, researching and rewilding Amazonian wildlife while empowering communities through education and sustainable solutions. 

**Hoja Nueva** is a 501(c)(3) nonprofit organization (EIN: 47-4323459) working at the forefront of wildlife conservation, research, and community development in the Peruvian Amazon. Our mission is to protect, rehabilitate, and rewild endangered species while fostering sustainable living and education in local communities. We believe that true conservation must go hand-in-hand with community empowerment, scientific research, and education to ensure long-term protection of the Amazon’s ecosystems.

At the heart of our work is the rescue and rewilding of iconic and threatened species—including jaguars, margays, pumas, jaguarundis, and tapirs—many of which suffer due to habitat loss, human-wildlife conflict, or illegal wildlife trade. Our state-of-the-art rescue and rehabilitation center provides expert medical care and pre-release conditioning to give these animals a second chance in the wild. With a 97% release success rate, our innovative rewilding techniques and long-term monitoring are helping restore the balance of nature in the Amazon rainforest.

Our **Sumamos Project** enhances animal welfare nationwide by promoting ethical practices in zoos and rescue centers. Through capacity-building, on-site training, and technical support, Sumamos elevates care standards and opens new possibilities for the recovery and eventual reintroduction of wild animals.

Research is a key pillar of our work. Hoja Nueva manages one of the largest camera trap networks in the Amazon, producing extensive data on mammal populations, activity patterns, and the impacts of human activity. Our findings have been published in peer-reviewed journals such as *Biotropica*, advancing global knowledge of tropical biodiversity. Beyond mammals, our **WildGenes Project** explores microbial diversity through non-invasive soil and fecal sampling. In collaboration with international partners like Cambridge University, this research contributes to a deeper understanding of the Amazon’s unseen ecological networks.

Hoja Nueva is also a leader in **community-based conservation**. Our **One Health** approach connects wildlife protection with human and environmental health. We work with rural villages like Puerto Lucerna to implement sustainable agriculture, waste management systems, and access to clean water—improving both community well-being and ecological health. Our dog and cat rescue program, which includes spay/neuter campaigns and veterinary services, helps reduce disease transmission and human-wildlife conflict, while improving the lives of animals and people alike.

Education is central to everything we do. We lead monthly workshops and conservation events for local students, teaching wildlife protection, environmental stewardship, and sustainability. Our international internship and research programs bring students and scientists from around the world to the Amazon for hands-on experience in wildlife care and conservation. Our six-month **Wildlife Rehabilitation Course** offers in-depth training in animal handling, clinical care, and reintroduction strategies for those pursuing careers in wildlife conservation.

Through our integrated programs in rescue, research, and community engagement, Hoja Nueva is creating a future where people and wildlife coexist in harmony, and the Peruvian Amazon thrives for generations to come.

Spritely Institute builds, researches, and standardizes networked technology which put people and communities first.


Centralized social media is harmful to society. We are building a gatekeeper-free decentralized system. Our mission is “social media done right”, to put people in control of their own identity and build the technology that would enable a shift to collaborative and intentional security models prioritizing active consent. To accomplish this, we will build a new architecture for the internet: removing the necessity of client-server architecture, replacing it with a participatory peer-centric model.

Spritely’s technology is being released as free and open source software aiming for multiple programming language implementations and eventual open standardization. All of our work, ranging from decentralized identity, peer-to-peer user agents, decentralized social networks, encrypted and portable storage, and distributed object programming infrastructure is being built to enable a gatekeeper-free path where users and content are not tied to a specific server.

Aquatic Life Institute is a 501(c)(3) non-profit focused on reducing the suffering of aquatic animals in the global food system.

Aquatic Life Institute (ALI) was founded in 2019 to address the critical and often overlooked issue of aquatic animal welfare. Recognizing that aquatic animals are the most exploited group of animals worldwide yet remain largely unprotected, ALI set out with a mission to drive systemic change and elevate aquatic animal welfare as a priority in global food systems.

Our theory of change is rooted in the belief that by influencing key stakeholders and decision makers, advancing policies, and fostering collaboration, we can drive systemic transformation for billions of aquatic animals. 

Building on this foundation, ALI has emerged as a thought leader, advocating for tangible improvements across the seafood supply chain. By engaging with key stakeholders, including corporations, certification schemes, and policymakers, we work to ensure that aquatic animals trapped in the food system receive the attention they deserve in decision-making processes relating to sustainability and food systems. 

ALI’s work is driven by evidence-based strategies and collaboration. This approach has earned ALI widespread recognition, including a 2024 Top Charity recommendation from Animal Charity Evaluators (ACE). This endorsement solidifies ALI’s position as one of the most effective organizations in the world advancing aquatic animal welfare.

Delivering unconditional cash directly to the world's poorest households via secure mobile transfers. 

Since 2009, GiveDirectly has delivered more than $580 million in unconditional cash transfers to families in need. These one-time cash transfers allow recipients to invest in what they need most and have been shown to improve their earnings, children’s school attendance, health, nutrition, and mental well-being.
 
GiveDirectly uses government data to target villages where most or all residents are living in extreme poverty, defined by the World Bank as earning under $2.15/day. In-country GiveDirectly staff enroll one member of each household in the entire village to receive a one-time transfer of about $1,000 USD sent in two installments using mobile money. Recipients can then withdraw the mobile funds as cash with local agents and use the funds to invest in what they need – whether it’s on starting a business, education, making their home safer/sturdier, healthcare, or livestock.
 
GiveDirectly uses rigorous experimental research (randomized controlled trials) to measure the impact of their unconditional cash programs and answer public policy questions, generating evidence on key design and implementation questions across varied contexts. You can find over 300 studies on the positive impacts of cash transfers in GiveDirectly’s Cash Research Explorer.

MAPS works towards a post-prohibition world by advancing research, changing policies, and shaping culture. 

Since our founding in 1986, the Multidisciplinary Association for Psychedelic Studies (MAPS) has been the leading organization building the movement to foster evidence-based approaches to psychedelics and the people who use them. When used safely and responsibly, psychedelics have the potential to promote personal growth and well-being and treat various mental health conditions. Three pillars guide our efforts: advancing research, changing policies, and shaping culture. 

[Advancing Research](https://maps.org/advancing-research/)

MAPS spent decades developing MDMA-assisted therapy for the clinical utilization of psychedelic-assisted therapies. With the road paved for the next generation of research and drug development, MAPS now stewards the research landscape we helped cultivate.

We are dedicated to fostering new research directions that prioritize public benefit, supporting international researchers and pilot programs, and ensuring the accessibility and culturally appropriate integration of psychedelics as a tool for individual and community wellness. We center research that contributes to knowledge in the public domain.

[Changing Policy](https://maps.org/changing-policy/)

The cultivation, use, and trade of psychoactive substances — including psychedelics — has been a consistent aspect of human history, but prohibition, criminalization, and militarization — and their inherent oppression — have led to drastic consequences. The ongoing, global War on Drugs has been justified by bad science, racism, and fear for too long: it has led to mass incarceration; erosion of civil liberties; ecological damage; economic waste; and the public health polycrisis of adulteration, poisoning, and overdose. Many of these harmful effects have disproportionately impacted the most historically exploited and oppressed communities. Consequently, we believe societies worldwide have an obligation to account for and repair those harms, to the extent possible. 

MAPS envisions a post-prohibition future based on Consciousness, not Criminalization.

[Shaping Culture](https://maps.org/shaping-culture/)

For psychedelics to be most safely integrated into society, we need to be honest about the implications. MAPS recognizes the importance of a comprehensive understanding of their risks and potential benefits, teaching people how to navigate altered states of consciousness and how policies impact individuals and communities. 

We create cutting-edge education for professionals and the public, provide expert support for the psychedelic and drug policy movement, and convene people who share our vision—all to lay the groundwork and create the guardrails necessary for responsible social transformation. 

As psychedelics become more mainstream and an increasing number of people seek to use them for healing and personal growth, we are more dedicated than ever to making resources available for people and communities to safely and responsibly integrate psychedelics into medical, legal, and spiritual contexts.
