Strange lights in old space photographs intrigue scientists

These photos show nine mysterious points of light appearing and then disappearing. Man had not sent anything into orbit at the time, which “means the nine non-terrestrial artifacts could not be space junk or satellites.” »

For the specialists, these lights cannot be from the contamination of the images, and they believe these strange artifacts deserve more attention. So we’re still looking for the origin.

Saudi Arabia wants to slow down aging

The Saudi royal family has set up an organization that can spend up to $1 billion annually to support research into slowing aging. many specialized researchers are in the starting blocks.

The goal of this organization is to extend the life of healthy people. It is even considering funding a $100 million prize to develop “aging reversal” technology.

The population of Saudi Arabia is something special, people who live in the Gulf States “age faster from a biological point of view”. The Saudi government even believes that aging threatens the future of the country, where obesity and diabetes are rising faster than other countries in the world.

In addition, trials of metformin, a drug known to be used by diabetics, are being carried out on several thousand elderly people, as this drug could delay the onset of cancer or Alzheimer’s.

A Mayan cooking secret discovered in latrines

Archaeologists have found Maya latrines from the 9th century BC. examined. And these latrines are crammed with information.

First, tapeworm eggs were discovered there, which means that the population must have suffered from diarrhea and weakness. It was also discovered there that the “flushing” of the latrines was drawn with lime water 3000 years ago.

And thanks to the study of these ancient latrines, archaeologists have understood that the Mayans also soaked and cooked corn in lime water, improving the grains’ nutritional values. This transformation is still practiced today, particularly to make the dough for tortillas.

French scientists have discovered new virtues in coffee

After water, coffee is the most consumed beverage in the world. We drink more than 2 million cups a minute!

Lille researchers have highlighted coffee’s benefits for memory and learning. In fact, regular consumption of caffeine permanently alters the molecular function of cells in the hippocampus. This leads to greater neural plasticity and can facilitate learning and improve memory.

Mice were also fed caffeine. Each day, the researchers gave the animals a small dose of caffeine orally. For humans, this corresponds to three cups of coffee per day. And after two weeks, the researchers examined the cells of their hippocampus. Well, caffeine leaves molecular “trails” in the hippocampus. We can therefore think that caffeine acts as a learning mediator.

A phase 3 study was even launched in Lille in 2021 to evaluate the effect of caffeine on the cognitive functions of patients with an early form of Alzheimer’s disease.
