Dongying enhances wetland conservation to safeguard migratory birds
DONGYING, China, June 26, 2025 /PRNewswire/ -- A news report from chinadaily.com.cn:
A critical stopover on two major migratory bird flyways, Dongying city in East China's Shandong province has emerged as a leader in habitat protection and ecological restoration within the Yellow River Delta.
In late April, the Yellow River Delta National Nature Reserve celebrated the hatching of its first artificially incubated crested ibis chick of the year — nearly a month earlier than in 2024.
The milestone was particularly welcome, because it's said to signal the growing adaptation of the species to the local environment.
"The earlier hatching provides the chick with more favorable conditions for growth and shows the crested ibis' successful acclimatization to the Yellow River estuary," said Wang Andong, head of the reserve's research center.
Once critically endangered, the crested ibis was reintroduced to the reserve in 2022 with 20 individuals translocated from Hanzhong city in China's Northwest Shaanxi province. By the 2024 breeding season, the population had already produced 20 new chicks through a mix of artificial incubation and natural breeding.
These achievements stem from years of targeted conservation efforts. Since 2016, Dongying has collaborated with research institutions to implement customized restoration techniques.
These include controlling invasive species like Spartina alterniflora, a coastal cordgrass native to the US, reviving native vegetation and supplying over 510 million cubic meters of ecological water in the past three years.
According to Zhao Yajie, deputy director of the reserve, an integrated monitoring system — combining satellite, aerial and ground-based tracking — enables real-time observation of bird activity.
In 2025, the reserve recorded a historic high of 233 oriental storks' nests, yielding 536 chicks. Staff also conduct satellite tracking and behavioral studies on juvenile birds to ensure their survival.
Fieldwork is viewed as remaining essential to Dongying's success. Zhao recalled wading through icy mud to rescue a fallen black-headed gull chick — a testament to the team's dedication.
Today, the reserve shelters 374 bird species — nearly double the original count. "With sustained ecological efforts, more species will continue to make Dongying their home," Zhao noted.

ESOT Congress 2025: Scientists create functional human islets in 3D printing breakthrough for type 1 diabetes treatment
LONDON, June 29, 2025 /PRNewswire/ -- A team of international scientists has made a major leap forward in diabetes research by successfully 3D printing functional human islets using a novel bioink. Presented today at the ESOT Congress 2025, the new technology could pave the way for more effective and less invasive treatment for people living with type 1 diabetes. The breakthrough involved printing human islets – the insulin-producing clusters of cells in the pancreas – using a customised bioink made from alginate and decellularised human pancreatic tissue. This approach produced durable, high-density islet structures that remained alive and functional for up to three weeks, maintaining strong insulin responses to glucose and showing real potential for future clinical use. Traditional islet transplants are typically infused into the liver, a process that can result in significant loss of cells and limited long-term success. In contrast, the 3D-printed islets were designed to be implanted just under the skin, a simple procedure requiring only local anaesthesia and a small incision. This minimally invasive approach could offer a safer and more comfortable option for patients. "Our goal was to recreate the natural environment of the pancreas so that transplanted cells would survive and function better," explained lead author Dr. Quentin Perrier. "We used a special bioink that mimics the support structure of the pancreas, giving islets the oxygen and nutrients they need to thrive." The bioprinted islets stayed alive and healthy, with over 90% cell survival. They responded better to glucose than standard islet preparations, releasing more insulin when it was needed. By day 21, the islets showed a stronger ability to sense and react to blood sugar levels – an important sign that they could work well after being implanted. The constructs maintained their structure without clumping or breaking down, overcoming a common hurdle in earlier approaches. Additionally, the 3D-printed structures featured a porous architecture that enhanced the flow of oxygen and nutrients to the embedded islets. This design helped maintain cell health and promoted vascularisation, both of which are critical for long-term survival and function after transplantation. "This is one of the first studies to use real human islets instead of animal cells in bioprinting, and the results are incredibly promising," noted Dr. Perrier. "We're getting closer to creating an off-the-shelf treatment for diabetes that could one day eliminate the need for insulin injections."

Drug-Free Nasal Spray LUCA V-Defense Creates a Protective Shield Against Viruses and Allergies
SEOUL, South Korea, June 27, 2025 /PRNewswire/ -- As respiratory illnesses like COVID-19, influenza, and Mycoplasma pneumonia continue to spread, the need for safe, non-pharmaceutical prevention options is growing. South Korea–based biotech firm LUCA AICELL has developed LUCA V-Defense Nasal Spray, a drug-free nasal spray designed to form a protective barrier on the nasal lining—offering a modern solution in the post-mask era. A Physical Barrier, Not a Medication Unlike traditional nasal sprays that rely on steroids or antihistamines, LUCA V-Defense forms a non-medicated barrier across the nasal mucosa, the body's first line of defense against airborne pathogens. Instead of using steroids, antihistamines, or vasoconstrictors, LUCA V-Defense relies on lambda carrageenan, a natural compound extracted from red algae, and antimicrobial lipids. These ingredients coat the nasal lining, helping to prevent viruses like SARS-CoV-2 and influenza from binding to mucosal cells. Recent studies have also shown that lambda carrageenan not only possesses antiviral properties but also exhibits anti-inflammatory and anti-allergic effects, helping to reduce allergic reactions in nasal tissues and inhibit histamine release, which may contribute to the prevention of allergic rhinitis. Using LUCA's proprietary lipid nanocoating technology, the nasal spray demonstrated 99.7% antiviral efficacy within one minute in an in vitro third-party COVID-19 lab study overseas. This suggests potential across a broad spectrum of respiratory viruses. Rapid Adoption and International Certifications LUCA AICELL reports that sales of LUCA V-Defense more than tripled in the most recent quarter, signaling increasing consumer interest in preventive nasal sprays. This demand is especially strong among parents and travelers, given that no vaccine currently exists for Mycoplasma pneumonia, a common threat to children. LUCA V-Defense is classified as a medical device, not a pharmaceutical. It holds: These credentials validate its safety for daily use and its alignment with international regulatory standards. Safer than Steroid and Decongestant Sprays Many popular nasal congestion sprays contain steroids or vasoconstrictors like methazoline, which can offer fast symptom relief but are linked to rebound congestion, mucosal thinning, and reduced efficacy with long-term use. LUCA V-Defense addresses these issues with a plant-based, non-pharmaceutical formulation that's free from steroids, antihistamines, and methazoline. It is gentle enough for children, pregnant women, and individuals who suffer from seasonal allergies or chronic rhinitis. Its ease of use, a simple mist inside each nostril, makes it ideal for travel, commutes, or high-exposure environments like offices, schools, or public transit. As the world transitions away from masks and into a new phase of pandemic management, personal preventive tools like LUCA V-Defense are gaining relevance. Whether navigating crowded airports, allergy season, or cold and flu outbreaks, this daily-use nasal spray offers a chemical-free alternative for respiratory defense. "The pandemic changed how we think about personal protection," said a LUCA AICELL spokesperson. "LUCA V-Defense was developed not just for short-term response, but for long-term respiratory wellness. We see it as a smart, science-backed addition to modern health routines."
