​New bad news for those hoping to discover extraterrestrial life ● Neanderthals may have disappeared because of too much sex with Homo sapiens ● It’s important to be optimistic even as climate disaster knocks on the door

Another bad news for those hoping to discover extraterrestrial life

A recent study published in The Astrophysical Journal Letters by a team of astrophysicists from the University of Nevada allegedly dashed the hopes of those hoping to find extraterrestrial life in the near future. Or at least it shows us that we have to change our strategies somehow.

For example, scientists claim, the attention of astronomers was directed, in particular, to stars of the category of red dwarfs, which are the most common in the Milky Way. The problem was that until now an interesting aspect had been left out, namely the lack of large planets in the zone that allows water to be stored in the form of ice.

Without such planets and without their gravitational influence, there is no asteroid belt. Asteroids that will be drawn into the depths of the solar system and that, bombarding planets in the habitable zone, could carry with them the seeds of life.

In summary, the chances of finding life even on planets in the habitable zone around a red dwarf are slim. Rather, the same researchers argue that we should be looking for solar systems like ours, which we don’t know why they didn’t do in the first place.

Neanderthals would have disappeared from excessive sex with Homo sapiens

Everyone knows that sometimes researchers say crazy things. There is nothing new. But if you dig deeper into what those who published an article on the subject in the journal PaleoAnthropology had to say, you can see that they were not too excited, as strange as it may seem.

They took into account the latest hypotheses, according to which Homo sapiens and Homo neanderthalensis interbred and gave descendants with common genes, that is, us today. In addition to this hypothesis, they also proposed a new hypothesis of unidirectional fertilization. We will immediately explain how it is.

For example, in the case of plants of the species Capsella rubella, their pollen can fertilize the seeds of another species, Capsella grandiflora. On the contrary, it is impossible. Well, that could be the case with two kinds of people. Indeed, only Neanderthal males and H. Sapiens females could produce viable offspring.

Considering that the Neanderthal population was very small, with weak intergroup interactions, the fact that they would have found sexual partners rather among H. Sapiens species seems plausible. Thus, hybrids of Neanderthal and intelligent will become predominant, and individuals with pure Neanderthal genes will gradually disappear, until extinction. Anyway, it’s nothing concrete, it’s just a hypothesis. But despite this, the saying “make love, not war!” does not always lead to the success of the species.

It’s important to be optimistic, even when climate catastrophe knocks on the door

It’s like telling people you have good news: 50% of the Earth will be habitable after 2023. The same with climate scientists at the University of Manoa in Hawaii. The scientists in question published a study in the journal Global Environmental Change through which they give us this news.

In particular, as we see less and less snow in the winter until we lose it altogether, we will see more rain. With the rains, we will have a chance to see more rainbows. Hooray! This was good news.

Please, that’s what all the research is about, which suggests, as I said, that it’s good to be optimistic in the face of any dangers that come your way. Ah, if you want to see such phenomena, it is good to find an island, preferably near Hawaii. It is there, they say, that they will be among the most frequent. If not, settle for the northern hemisphere because there are enough to cover everyone.
