    Injured birds seeking medical help

    Injured seabird desperately pecks at hospital door for help

    An injured seabird sought help by pecking at the door of an emergency room at a hospital in Germany until medical staff noticed it and called firefighters to help with its rescue.

    The cormorant, a shiny black waterbird, had a triple fishing hook stuck in its beak when it made its presence known at the glass door of the Klinikum Links der Weser hospital in the northern city of Bremen on Sunday.

    In a joint effort, medical staff and firefighters removed the fishhook and treated the wound, the Bremen firefighter department said in a statement. The bird was later released back into nature on the grounds of the hospital park.

    "When an injured cormorant does approach humans, it is usually an animal in extreme distress that has lost its natural shyness," the statement said.

    A cormorant is a large bird with a long neck, wedge-shaped head and a distinctive sharp beak with a hooked tip. A fishhook in the bird's beak would be extremely dangerous for the animal. Infections, pain and even starvation are possible, the firefighter department said.

    Want a tall, smart child? How IVF tests are selling a dream


    Genetic tests marketed to IVF parents claim to predict traits like height and intelligence using polygenic risk scores, but these predictions are highly uncertain and offer minimal benefit—typically only a few IQ points or centimeters in height. Environmental and lifestyle factors play a much larger role in child development, and using such tests poses ethical, psychological, and medical risks without proven advantages.

    Yes, men have a biological clock too. But it's not just age that affects male fertility


    Male fertility declines with age, with sperm count, motility, morphology, and semen volume decreasing from the early 20s, and genetic damage in sperm increasing, raising miscarriage and birth defect risks. Environmental and lifestyle factors, such as oxidative stress, toxins, smoking, obesity, and certain medical conditions, also impact male fertility. New guidelines recommend simultaneous fertility assessment for both partners.
