Author: Natural World 50 News Agency Scientific Breakthrough in Heart Transplants Researchers from Vanderbilt University Medical Center have developed a pioneering method for preserving donor hearts called REUP (Recovery via Ultraoxygenated Perfusion). This technique could dramatically increase the availability of viable donor organs and reshape heart transplantation worldwide. “This is a game-changer,” said Dr. Aaron Williams. “It’s never been successfully used in heart transplants before. We expect it to be adopted globally.” Why This Innovation Matters Traditionally, hearts from donors after circulatory death (DCD) have been underutilized due to their fragile condition and the ethical or financial constraints of reanimation. REUP bypasses these obstacles by using a cold, oxygen-rich solution to flush the heart shortly after death — no machines or reanimation required. Preserves heart viability for up to 8 hours Eliminates need for expensive perfusion ma...

In a recent interview, ecology expert Kutsokon emphasized that even if catfish (“somy”) grew as large as 500 kg, they would pose no threat to humans or ecosystems in Ukraine. She clarified that while folklore sometimes mentions massive fish, the evidence doesn’t support it. What do scientists say? The European catfish ( Silurus glanis )—the largest freshwater fish in Ukraine and Europe—can grow up to 5 m and weigh around 100 kg when 80–100 years old. However, specimens over 100 kg are now extremely rare due to overfishing and environmental pressure. There are occasional anecdotal reports of catfish claiming weights up to 300 kg or lengths up to 4 m, including sightings in lakes of the Shatsky National Park. One ichthyologist reported seeing a catfish nearly 4 m long during spawning season in Lake Svityaz 2. Still, these remain exceptional and unverified. Is 500 kg realistic? According to Kutsokon, even if a catfish reached 500 kg, it wouldn’t threa...
