Concerning Levels of Arsenic And Lead Found in Tampons in World First Study

Weighing up the pros and cons of different sanitary products requires sound knowledge of what risks and benefits each poses.

Weighing up the pros and cons of different sanitary products requires sound knowledge of what risks and benefits each poses. For the first time, researchers have measured concentrations of various metals in tampons, finding worrying levels of several toxic types, including lead, for which there is no safe level of exposure. The walls of the human vagina are lined with a highly absorptive tissue that has the potential to soak up stray pollutants – like metals – that would circulate in the bloodstream without being filtered by the liver first.

This lie was pushed by the White House as well as every major Western news source...

who still haven't recanted it with anywhere near the energy they spread it with.

Uncharismatic Fact of the Day

It's not every day you see a fish walking on land! However, when the streams and ponds of the airbreathing catfish dry up, this species will readily wriggle across the jungle floor in search of a new home. Thanks to a special organ called a labyrinth organ, they are able to breathe air and can remain outside of water for several hours provided they stay moist.

The Y Chromosome Is Slowly Vanishing. A New Sex Gene May Be The Future of Men.

The sex of human and other mammal babies is decided by a male-determining gene on the Y chromosome.

The sex of human and other mammal babies is decided by a male-determining gene on the Y chromosome. But the human Y chromosome is degenerating and may disappear in a few million years, leading to our extinction unless we evolve a new sex gene. The good news is two branches of rodents have already lost their Y chromosome and have lived to tell the tale. A 2022 paper in Proceedings of the National Academy of Science shows how the spiny rat has evolved a new male-determining gene.

Here it finally is, the full cetacean eye colour info sheet! A long time coming, and an even longer time in the making. I hope that all you cetacean eye curious people will find this one as fascinating as the killer whale eye colour post. It’s a wild world out there! 

What makes the dark shyshark (Haploblepharus pictus) so shy? When threatened, this critter might curl up into a ring and cover its eyes with its tail. Scientists think this defensive posture makes it harder for predators to gulp the dark shyshark down for an easy meal. Found in parts of the southeast Atlantic Ocean, this shark can grow to about 22 in (55.8 cm) long. Its diet includes crustaceans, mollusks, and fish.
