OVER 80 YEARS, LOTS OF MEMORY AND A BRAIN WITH “SUPEREURONES”
There are people over 80 who retain an exceptional memory. These “super-elders” have significantly larger and healthier neurons in a region of the brain linked to memory. These neurons are even larger than those of people 20 to 30 years younger and do not have a characteristic of Alzheimer’s, says a study from Northwestern University (USA) published by The Journal of Neuroscience. Lead author of the research Tamara Gefen said they believe larger neurons “are a biosignature of the superaging trajectory” – they may be present from birth and structurally maintained throughout life. The university has a “superaging” research program that studies people over 80 who show memory at least as good as individuals 20 and 30 years younger.
I SEE YOU AND I REALIZE THAT YOU ARE STRESSED!
Dogs are able to smell a stressed person, as physiological processes associated with an acute psychological stress response produce changes in human breathing and sweat that these animals pick up with 93.75 percent accuracy, according to research made in UK. Breath and sweat samples were taken from fasting non-smokers before and after a fast-paced arithmetic task. The dogs managed to differentiate the breath and sweat of the stressed people while they solved the exercise (photo).
“Staying in a hotel in space will be a reality in 2025. We will have windows from which to see the earth and the stars, games and sports; In addition, we are going to have a mix of gravity, you will be able to enjoy microgravity, play in artificial gravity and simulate what it is like to walk on the moon”
Chief Operating Officer of Orbital Assembly
The American architect of Mexican origin Tim Alatorre devised the company Orbital Assembly and will open a space hotel in 2025. First, he will place a 400 m2 module with eight rooms in Earth orbit, of which four will be rooms, and in which four people.
AMASIA, EARTH’S NEXT SUPERCONTINENT
In its 4.5 billion years, the Earth was made up of several “supercontinents”. So far, there is evidence that three existed: Columbia -also called Nuna- was formed 1.8 billion years ago; Rodinia, about 1,000 million years ago, and Pangea, 300 million years ago. After the rupture of Pangea, the seven current continents were formed: South and North America, Asia, Africa, Europe, Oceania and Antarctica. But these won’t be final, as the Earth’s crust is on track to form another large landmass, Amasia, in about 200 to 300 million years, when the Pacific Ocean closes. A team from the University of Curdi, Australia used a supercomputer to simulate how a supercontinent forms and found that due to the Earth’s cooling over billions of years, the thickness and strength of sub-oceanic plates reduce over time. This makes it difficult for the next supercontinent to assemble by closing the “young” oceans, such as the Atlantic or the Indian.
A married couple from Bad Salzuflen, Germany, sued their neighbor in court to demand that their neighbor get rid of his rooster, which tortures them with its crowing more than 200 times a day.
THE STONE AGE GLUE
The first time that Homo Sapiens used a self-made adhesive, according to evidence, was in Africa, in the so-called Middle Stone Age, which may be an indicator of the cognitive and technological development of that time. Chemical analysis of adhesives preserved as residue on stone tools found in South Africa suggests they come from the resin of the conifer genus Podocarpus, according to a study from the University of Tubingen, Germany. Currently, Podocarpus does not exude substances with adhesive properties.
MORE THAN A DIAMOND IT LOOKS LIKE THE “CRYSTAL BALL”
The study of a rare diamond that originated 660 km below the Earth’s surface confirms the presence of mineral-bound water at that depth and potentially beyond, according to a study published in Nature Geoscience. The research led by Tignting Gu of the American Institute of Gemology suggests that there is a largely water-saturated environment that extends into the Earth’s lower mantle.
The team analyzed a gem-like diamond from the Karowe mine in Botswana, which had been trapped and protected by a sample of the Earth’s lower mantle on its journey from a depth of about 660 km to the surface. During the study they found evidence of the presence of ringwoodite and other minerals and hydrous phases in the diamond, indicating that it formed in a hydrated region of the Earth’s mantle, according to the team, who believe that these findings improve our understanding of the cycle of the Earth’s deep water.
CALM, THE COCKROACHES THAT RETURNED DON’T EAT MEAT!
Days ago, a team of researchers from the University of Sydney announced the reappearance of a wood-eating cockroach in Australia after almost 90 years. However, when the news was replicated by media in Spanish, it was said that the species was “carnivorous”.
The confusion stems from a mistranslation of the institution’s press release: the text reads “wood-eating cockroach,” which means “wood-eating cockroach.” But Google, for unknown reasons, automatically translates it as “carnivorous cockroach”. The cockroach found, whose scientific name is Panesthia lata, is exclusive to Lord Howe Island (Australia) and was believed to be extinct since the 1930s. P. lata are between 2.2 and 4 cm long. They have a metallic color that varies from reddish to black. They carry specialized microorganisms inside them that help them digest the cellulose in the wood. They are key to the ecosystem of Lord Howe Island, as they act as nutrient recyclers.
