Viruses hit men the hardest - because they are less useful

Infections often strike harder in men than in women. This is perhaps due to the fact that bacteria and viruses have much more to women than to men.

Men's flu is one thing - all kinds of illnesses that are a lot more deadly to men are something else.

Men with tuberculosis are 1.5 times more likely to die from this disease than women. And men run a 5 times greater risk of cancer if they are infected with HPV.

Women are the first choice

A research team from the University of London believes it has discovered why.

Women are more valuable as carriers of so-called pathogens - pathogens such as bacteria and viruses - and therefore keep women alive longer than men.

Causing a disease is not a goal in itself for pathogens. In fact, it suits them well if the host stays alive, because then they can multiply and jump from one host to another.

Women infect better

Men can transmit infection in one way: contact with others.

But women have more opportunities to spread a virus or bacteria: in addition to contact with others - for example by having sex or sneezing - they can also transmit an infection through pregnancy, birth and breastfeeding.

The scientists examined the HTLV-1 virus, which can develop into a certain form of leukemia, ATL called. That virus is found in Japan and the Caribbean, and in Japan, men have a 3.5 times higher risk of developing ATL than women. In the Caribbean, as many men and women receive ATL.

ATL jumps from mother to child, and according to the scientists the virus "wants" to keep Japanese women alive longer because they breastfeed more, and keep it up longer.

What makes animals' eyes shine in the dark?

That the eyes of cats and other animals glow in the dark is due to a layer in their eye, the tapetum lucidum. This layer is behind the light-sensitive retina and reflects the light that passes through it. The light-sensitive cells in the eye can use the light again. The reflection increases the light sensitivity of the eyes considerably (with cats by around 50 percent) and is therefore especially useful for nocturnal animals.

Why do dogs wag?

A dog's tail has two main functions. The first is balance: it helps the dog to stay in balance while running and jumping. For example, if the animal suddenly wants to change direction, it uses its tail as a kind of counterweight to turn its abdomen. The second function is communication.

The long legs of frogs work as a slingshot Frogs are among the best jumpers in the entire animal kingdom. Some species can jump up to 20 times their own height. Because of their long legs, they can deposit longer, giving them more jumping power. Before they jump, frogs put on their leg muscles, tightening the tendons in the ankles like a catapult.
