Stop eating pheasants! They are polluted

A heavy blow to people everywhere! After everything has become more expensive, you will now have to give up one of life’s last little pleasures, namely game meat. Especially the pheasant, but you should also take care of rabbits, deer, partridges, grouse, and other small animals that the common man usually eats. Why are we forced to resort to such a drastic measure? Well, a new study tells us published in PlosONE that the animals in question are hunted with lead-based ammunition.

Alice, yes. And that lead leaves tiny particles in the flesh, particles that later enter your physical body. And this is not good for health. And it is not only ordinary people who suffer from the consumption of lead particles, but also carnivores or scavengers who consume scavengers left by hunters who simply want the carcasses. Very disgusting! This issue was raised both in Great Britain and in EU bodies.

Careful about the health of its citizens, the EU is considering some measures to prevent contamination of the population with harmful substances. So, the ban of lead alices, which have been around since the time of Pazvante, and their replacement with steel ones, is being discussed. In conclusion, here is a drama of hope for the best.

Do puppies cry with happiness when they see their owners?

It would seem that we are told by some Japanese researchers who have done serious research on the subject, what kind of research are they published in Current Biology. In any case, the unequivocal answer is: we don’t know! Let’s explain how it was.

These Japanese analyzed about 18 puppies, namely the moments when they are reunited with their owners after a period of separation. So they observed a 10 percent increase in tear volume in all samples. If those puppies met strangers, their tails hurt. Thus, the researchers came to the conclusion that positive emotions can make not only people cry, but also our best friends.

To verify the result, they took 22 other dogs and dripped a substance based on oxytocin, the happiness hormone, into their eyes. Then cry on all fours, tears as much as quince! Guaranteed success, science and accuracy, Japanese scientists concluded! That was until others came along and told them that many species of animals actually shed tears to clear their eyes of impurities. Then, if you pour a solid substance on the animal’s eyeball, even if it is based on oxytocin, you risk irritating the eyes of life, which leads to the appearance of profuse tearing. As I told you, a clear answer to this question is yet to come, so we will have to live with this uncertainty for a while longer.

What you need to know when starting to build a sandcastle

Going to the beach and building a sandcastle on the water’s edge is not as easy as it seems. This is actually not true at all, especially if you have been to the beach recently. First of all, because you don’t really see how the banks of despair spread their blankets nearby. To get to the water, you would need both a stick and the talent of Serhiy Bubka. But that’s not what research is about published in The Conversation, and about the fact that you worked for amateurs. If you want to make a solid, impressive and scientifically sound castle, you should follow the steps outlined by the engineers quoted in the article.

First of all, you need to pay attention to the size of the grains of sand. They range from 0.0075 mm to 4.75 mm. You need both fine sand and coarser sand to be successful. This is the first secret. Next, you need to pay attention to the shape of the granules. Choose the ones with straight corners and discard the ones with rounded corners! In fact, say the study’s authors, professionals order their sand from mountainous areas because that’s where it has most of the listed attributes. So maybe you’d better run to the mountains and get your sand from there first. As you like, it was just a suggestion.

Finally, water is key. Without water, you’ll have a pile of sand shaped like… a pile. Too much water is not good. The same is true if you have too little. Scientists have calculated, and the ideal combination is one measure of water to eight measures of dry sand. Seawater is ideal because after it evaporates, the salt crystals keep the lock standing longer. You can use buckets, shovels and other useful tools without restrictions! As I said, this is serious business.

Why do mosquitoes chase us?

As you know, only female mosquitoes feed on blood. Men, more polite, are avid vegetarians. Well, when a female looks at you, she’s actually looking for a scent. Our body emits a series of smells, a veritable olfactory cocktail that is extremely appetizing to mosquitoes. In this vein, scientists tried to suppress receptors in the antennae of mosquitoes so that they could no longer smell people. By the way, the study of published in the journal Cell.

Normally, people should have become “invisible” to mosquitoes. This was not the case, much to the surprise of the researchers involved in the study. And this is a unique feature of mosquitoes. In humans, for example, if you inhibit one of these receptors that identifies a certain odor, all the neurons that are connected to that receptor will lose their ability to recognize the odor. Not to mosquitoes. They were developed specifically to avoid such shortcomings. It turns out that even when their receptors are suppressed, mosquito brains, or whatever they contain, can process information related to amines, organic compounds similar to ammonia.

And that’s just part of how they’ve adapted to find you, because of course there are others that scientists haven’t yet identified. In conclusion, you might as well hide in a snake hole because the mosquito will still find you. What remains for us to do, at least until we reach the level of research, is to resort to ancestral methods. That is, let’s solve them with an envelope or, if we don’t have envelopes, scientifically, with a slap on the back of the head. It also goes well with several beers. It is not necessary that the mosquitoes no longer sense you, but you no longer sense them.
