Thanks to an innovative surgery using fish skin grafts, Kere, a rescued bald eagle, returned to flight over Wisconsin on June 22 after surviving a life-threatening leg injury.
Why It Matters
Bald eagles, the national symbol of the United States, have faced near extinction in the past, with each rescue effort highlighting conservation progress and ongoing challenges.
In Kere's case, the pioneering use of fish skin grafts to heal traumatic wounds in wildlife opens a potential new chapter in animal medical care.
The bald eagle's release came days ahead of July Fourth celebrations, restoring an emblem of American freedom to the wild.
What To Know
Kere's 10-month recovery was led by Dr. Kim Ammann, a raptor specialist and founder at the Winged Freedom Raptor Hospital, a press release provided to Newsweek said.
The treatment represented the first time a bald eagle received this type of skin graft that was provided by Icelandic firm Kerecis.
Kere was discovered in Hayward, Wisconsin, in September 2024 with a 360-degree wound running from her knee to her ankle.
The injury left no healthy skin for traditional treatments and infection threatened her survival.
Ammann then stepped in to provide care.
"With no traditional options left, she turned to innovative alternatives and discovered an Icelandic company called Kerecis that uses intact fish skin from sustainably sourced North Atlantic Cod to support tissue regeneration," the press release said.
Kerecis, known for developing fish skin grafts for humans, had only recently begun offering veterinary products.
Over 10 months, the cod skin grafts supported tissue regeneration and helped combat infection, which improved Kere's prospects.
"The trust she put in me made it possible to accomplish what we did. She tolerated bandage changes every few days for months," Ammann said.
Ammann, who treated over 200 birds in the past year, including 75 bald eagles, noted that Kere's case demonstrates the importance of innovative veterinary efforts.
The successful use of fish skin grafts may open doors for wildlife rescue centers and veterinarians nationwide.

Dr. Kim Ammann, founder of Winged Freedom Raptor Hospital, said about Kere: "She left the wraps and dressings alone as they were healing her wound. She was eating well and taking necessary medications the whole time."
Marta Hines, veterinary business development manager at Kerecis, said in the press release: "Our fish skin grafts are used in a variety of different wounds, whether those are traumatic wounds or some that have been out there for a while, and they have not closed in a while, like chronic wounds."
What Happens Next
The Winged Freedom Raptor Hospital continues to seek support for its conservation and rehabilitation activities.
Kerecis, meanwhile, has indicated continued research and development of its veterinary products.

Texas politicians lead effort to study a psychedelic drug. What is ibogaine?
Ibogaine is illegal in the U.S., but growing evidence shows its promise treating the effects of traumatic brain injury and substance use disorder. A once obscure traditional psychedelic plant from Africa has made headlines recently as Texas pushes for more research and a prominent Republican wrote a vigorous endorsement of its possible use for the treatment of addiction and for veterans experiencing mental health issues. Ibogaine is illegal for use in the United States, but a growing body of evidence has shown its promise treating the effects of traumatic brain injury and substance use disorder. Earlier in June, Texas Gov. Greg Abbott signed legislation to allocate $50 million for clinical trials approved by the Food and Drug Administration to study ibogaine. Texas is set to lead research into the drug's benefits treating mental health issues and addiction as a potential medication. Former Energy Secretary Rick Perry, also a former Texas governor, wrote a June 27 Washington Post op-ed supporting ibogaine research and criticizing the legacy of the war on drugs, started by President Richard Nixon and touted by President Ronald Reagan. Perry said he has 'come to realize just how wrong that narrative was.' 'That fear-based messaging kept us from exploring treatments that could have saved countless lives,' Perry wrote. Perry and a growing number of conservatives have argued ibogaine could be one of those treatments. Here's what to know about the drug. What is ibogaine? Ibogaine derives from the root of the iboga plant native to western-central Africa. It's been used in ceremonial rituals for centuries. It has hallucinogenic properties. The United States outlawed ibogaine in 1967 along with other psychotropic drugs. The Controlled Substances Act of 1970 placed it as a schedule I hallucinogenic drug, along with marijuana. Ibogaine's classification prevented researchers from studying its effects. But unlike other schedule 1 drugs such as heroin, ibogaine has anti-addictive properties. There are risks since ibogaine can delay the body's normal electrical signals that control heart rhythm, which could lead to death. Other countries, such as Mexico, have allowed its use. American veterans and others have traveled to smaller, clandestine clinics for treatment to deal with depression, post-traumatic stress disorder and addiction. Many clinics are along the border and around cities such as Tijuana. Why is it in the news? At the state and federal level, there is growing interest in studying psychedelic drugs to treat veterans and others. Texas passed legislation earlier in June to study the drug with a public university alongside a company and hospital, Abbott's office said. Dr. Marty Makary, the FDA commissioner, has said expanding research on psychedelic drugs is a top priority for the Trump administration. In his op-ed, Perry cited the experiences of Morgan and Marcus Luttrell, twin combat veterans, who used ibogaine for recovery. Morgan Luttrell is now a Republican congressman from Texas who has advocated for ibogaine and other psychedelic drugs as treatment options. In January 2025, Perry and W. Bryan Hubbard, an advocate for ibogaine treatment, appeared on Joe Rogan's podcast to discuss ibogaine's benefits as a plant-based medicine. Hubbard led a Kentucky task force that sought to use opioid settlement funds to research ibogaine's effects to treat addiction, but the initiative failed to gain support in the state. Hubbard and Perry eventually launched the Texas Ibogaine Initiative, which helped spur the state funding. What has research shown? Research, such as a Stanford University study of 30 male combat veterans, has shown ibogaine's promise. Coupled with magnesium sulfate to address heart effects, ibogaine appeared to reduce symptoms of PTSD, anxiety and depression, and improve cognitive function from traumatic brain injury, according to the study, published in 2024 in the eminent journal Nature Medicine. Other studies have shown benefits treating addiction and depression. What do critics say? One issue with ibogaine is the ability to produce it, because it is derived from a rare plant and has mostly been used for ceremonial purposes. There is research to help innovate its safe production, but it could be difficult for the drug to be more widely available, as researchers at the University of California, Davis, Institute for Psychedelics and Neurotherapeutics have said. And while it's shown benefits with combat veterans, questions remain on its efficacy among randomized participants. With Texas' research, ibogaine could get closer to FDA approval for its use as a medication.

This New Test Could Diagnose Parkinson's With AI
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A new artificial intelligence (AI) tool analyzing short smile videos achieved high accuracy in screening for Parkinson's disease (PD), according to research published by Tariq Adnan, and colleagues in the New England Journal of Medicine (NEJM) Thursday. The model was trained on the largest known video dataset of facial expressions to date, enrolling 1,452 participants, including 391 living with PD. An 87.9 percent overall accuracy in detecting PD using only smile video analysis, the NEJM AI study reported. Researchers reported that the AI model could accurately distinguish between individuals with and without PD based on the analysis of their smiles, even when applied in diverse population samples from North America and Bangladesh. Why It Matters The Parkinson's Foundation says an estimated 90,000 more people will be diagnosed this year, with the number of those suffering expected to be around 1.2 million by 2030. Diagnosing Parkinson's disease early remains a significant challenge because of limited access to clinical expertise and in-person evaluations. AI-driven remote screening tools promise scalable, cost-effective solutions to bridge these healthcare gaps. The findings align with the growing demand for digital healthcare solutions that remove geographical and economic barriers to early neurological disease diagnosis, which is especially relevant to rural and underserved American communities. What To Know The new screening method invited participants to record themselves mimicking facial expressions—including a smile—using an online platform. Research teams then extracted facial landmarks and measured action units to quantify hypomimia, a common motor symptom in PD where facial muscle movement is diminished. Machine learning models were developed using these features, distinguishing people with PD from those without. The approach relied on a broad recruitment strategy, involving participants from North America via social media, email, wellness centers, and research registries, alongside a high-risk cohort from Bangladesh. Trained solely on smile videos, the model achieved a 10-fold cross-validated accuracy of 87.9 percent, a sensitivity of 76.8 percent, and a specificity of 91.4 percent. Validation in external test sets revealed 80.3 percent accuracy in a U.S. clinic dataset and 85.3 percent accuracy in the Bangladesh cohort. While the negative predictive value remained above 92 percent in all settings, the positive predictive value dropped to 35.7 percent among the Bangladeshi participants, reflecting variations in population characteristics. The study found no significant differences in model performance across sex and ethnic subgroups, except for marginally higher accuracy in female participants in Bangladesh. The authors emphasized the generalizability and fairness of the approach, key considerations in the development of clinical AI tools. The video-processing and machine-learning code supporting the study is available to the public on GitHub. However, the study authors noted that raw video data sharing is restricted to comply with U.S. healthcare privacy law (HIPAA), limiting access to de-identified derivative features only. The research received funding from the National Institute of Neurological Disorders and Stroke at the National Institutes of Health, among other sources. The work was a collaborative effort involving academic and clinical partners such as the InMotion Parkinson's Disease wellness center and the University of Rochester Center for Health and Technology. The research process also benefited from contributions by staff at Google Research and the University of Rochester, particularly in statistical analysis.

Getty What People Are Saying Tariq Adnan, lead author said in the study conclusion: "Smiling videos can effectively differentiate between individuals with and without PD, offering a potentially easy, accessible, and cost-efficient way to screen for PD, especially when access to clinical diagnosis is limited." What Happens Next? Future steps for the research team involve wider validation of the AI screening method in additional, real-world populations and further refinement of the algorithm to maximize early detection accuracy. Regulatory and clinical translation pathways will determine if and when this technology becomes available in the United States healthcare system.
