In DNA some people are genes of unknown to the science of ancient man

A recent study of the genomes of the two most famous types of ancient humans – Neanderthals and denisovans – discovered new previously unknown ancestor of modern man.

There is a possibility that this unidentified ancestor in fact belonged to Homo erectus, which is believed to have been extinct for over 100 thousand years ago. But since there are not found any DNA of Homo erectus, sure to be impossible.

In this study, scientists from cold spring Harbor (USA) used a Bayesian algorithm ARGweaver-D to explore patterns within the genomes – in this case, the DNA of two Neanderthals, Denisova and one of two modern Africans. The resulting model can match the facts of the mixing of DNA with specific historical time periods. At the end of its work it turned out that about 1% of the DNA of the ancient denisovans has the unknown origin.

Approximately 15% of detected “superdrink” regions of DNA that were found in the genome of the denisovans, is still present in the genome of modern humans. What happened to the lost kind, from whom we received them, remains to be seen.

Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes. […]

Looks like a screwdriver of the XXI century

Recently Techcult wrote about the drill of the XXI century with a touchscreen and lasers. But the screwdriver is traditionally considered to be more simple, reliable and very straightforward tool. What similar high-tech screwdriver advanced Italian production? And it is similar to the Kinetic device Driver. Kinetic Driver designed by the Italian designer Giacomo Di […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]

Some homemade masks turned out to be more dangerous than no

Despite the fact that the industry has recovered from the shock of the first days of the pandemic COVID-19 and now produces enough facial masks of different types, most people in the world due to various reasons use homemade versions. Everyone understands that they are less effective than professional medical model, but the question is: […]
