New technology allows you to print words with the power of thought
Scientists from the US state of California have created a technology that allows people to write text messages with the power of thought. They implanted several chips in a person's head that read the activity of his brain and convert it into handwritten text on the screen. It is believed that this technology will return the paralyzed people the opportunity to communicate with their relatives and the wor...
Embryos of many species use sound to prepare for the outside world
It's well known that reptiles depend on temperature cues while in the egg to determine a hatchling's sex. Now, researchers writing in the journal Trends in Ecology & Evolution on May 26 say that embryos of many different animal species also rely on acoustic signals in important ways. They call this phenomenon "acoustic developmental programming." "Acoustic developmental programming occurs when a so...
New data has confirmed that the extinction of the dinosaurs began long before the asteroid hit
Non-avian dinosaurs began to lose in the struggle for survival millions of years before the Cretaceous-Paleogene extinction, and the reason for this is the cooling and the appearance of more advanced competitors. All non-avian dinosaurs became extinct during the Cretaceous-Paleogene extinction event, about 66 million years ago. It is believed that it was launched by the fall of a massive celestial body tha...
Russian scientists used the body's own bacteria instead of probiotics
Scientists of the Pavlov Institute of Physiology of the Russian Academy of Sciences and the Institute of Experimental Medicine have shown the effectiveness of using autoprobiotic bifidobacteria to normalize the intestinal microbiota in a state of dysbiosis. The widespread use of probiotics (beneficial bacteria that are usually part of the human and animal microbiota) in medical practice in recent decades h...
Singapore scientists develop novel gene editor to correct disease-causing mutations
A team of researchers from the Agency for Science, Technology and Research's (A*STAR) Genome Institute of Singapore (GIS) have developed a CRISPR-based gene editor, C-to-G Base Editor (CGBE), to correct mutations that cause genetic disorders. Their research was published in Nature Communications on 2 March 2021. One in seventeen people in the world suffers from some type of genetic disorder. Chances ar...
WHO guidance on Artificial Intelligence to improve healthcare, mitigate risks worldwide
Artificial Intelligence (AI) holds “enormous potential” for improving the health of millions around the world if ethics and human rights are at the heart of its design, deployment, and use, the head of the UN health agency said on Monday.  “Like all new technology, artificial intelligence…can also be misused and cause harm”, warmed Tedros Adhanom Ghebreyesus, Director-General of the World health Organizati...
Analysis of ancient DNA revealed the history of Denisova cave
In a new study, an international team of scientists analyzed DNA from more than 700 sediment samples collected from the Pleistocene layers of the Denisova Cave in Siberia, and found ancient mitochondrial DNA (mtDNA) of hominins and mammals in 685 samples and 175 samples, respectively. The earliest evidence of hominin mtDNA is from Denisovans and is associated with stone tools that were deposited approximat...
