Forever chemicals are altering the DNA of unhatched ducklings

Regulation is needed to prevent PFAS being ingested by female ducks and then passed on to their eggs

Thousands of man-made chemicals might be interfering with the genes of birds before they hatch, according to a recent study on ducklings.

Scientists at the Norwegian University of Science and Technology (NTNU) injected small amounts of per- and polyfluoroalkyl substances (PFAS) into mallard duck eggs and then studied what happened to them.

They found that the chemicals interfered with the ducklings' DNA, switching genes on and off in several organs, and potentially damaging their chance of survival.

PFAS, otherwise known as forever chemicals, are a group of man-made substances that take a very long time to break down in the environment.

ARE PSYCHOPATHS REALLY THAT GOOD AT LYING?

Picture infamous psychopaths from fiction, such as the eerily cold and calculating Patrick Bateman in the film adaptation of American Psycho, and they certainly seem like master deceivers. But what about real-life psychopaths? Research confirms that psychopaths are more inclined to lie to get what they want, and that they typically display a striking fearlessness - as if they have ice running through their veins.

WHY DO WE HAVE TWO OF SOME ORGANS, BUT ONLY ONE OF OTHERS?

The majority of animals on Earth, humans included, are bilaterally symmetrical. It means we can be divided roughly into two mirror-image sides. Evolutionary biologists believe that it has been like that for at least 300 million years, and because life organised this way survived, so did symmetrical design. Hence, two eyes, two ears, two lungs and two kidneys.

THE AARDVARK

In a time when people are being asked to consider eating insects, we should, perhaps, learn a thing or two from the aardvark (Orycteropus afer), Africa’s ant-guzzling gourmand. On an average night, the big-schnozzed mammal devours up to 50,000 of the crunchy critters.
