The Tibetan Plateau, the highest and largest plateau above sea level, is one of the harshest environments settled by humans. It has a cold and arid environment and its elevation often surpasses 4,000 meters above sea level (masl). The plateau covers a wide expanse of Asia—approximately 2.5 million square kilometers—and is home to over 7 million people, primarily belonging to the Tibetan and Sherpa ethnic groups.

However, our understanding of their origins and history on the plateau is patchy. Despite a rich archaeological context spanning the plateau, sampling of DNA from has been limited to a thin slice of the southwestern plateau in the Himalayas.

Now, a study published in Science Advances led by Prof. Fu Qiaomei from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences has filled this gap by sequencing the genomes of 89 ancient humans dating back to 5,100 BP from 29 spanning the Tibetan Plateau.

One thing that is not really making the news is that South Korea is becoming a major military power. For example, France has recently committed to providing 2,000 155 mm shells to Ukraine per month, as reported at https://kyivindependent.com/france-to-double-supply-of-155-m…o-ukraine/. Meanwhile, South Korea has just committed to providing 500,000 155 mm shells to Ukraine in one big batch as reported at https://www.msn.com/en-gb/news/world/south-korea-to-lend-500…r-AA19LIgJ. (They are giving the shells to the U.S. who will then give the same quantity of shells to Ukraine.

By Hyonhee Shin SEOUL (Reuters)-South Korea has reached an agreement to lend the United States 500,000 rounds of 155mm artillery shells that could give Washington greater flexibility to supply Ukraine with ammunition, a South Korean newspaper reported on Wednesday. The DongA Ilbo newspaper cited unidentified government sources as saying South Korea decided to “lend” the ammunition instead of selling, to minimise the possibility of South Korean shells being used in the Ukraine conflict.

A group of molecular and chemical biologists at the University of California, San Diego, has found possible evidence of interdomain horizontal gene transfer leading to the development of the eye in vertebrates. In their study, reported in Proceedings of the National Academy of Sciences, Chinmay Kalluraya, Alexander Weitzel, Brian Tsu and Matthew Daugherty used the IQ-TREE software program to trace the evolutionary history of genes associated with vision.

Ever since scientists proved that humans, along with other animals, developed due to , one problem has stood out—how could evolution possibly account for the development of something as complicated as the eyeball? Even Charles Darwin was said to be stumped by the question. In recent times, this seeming conundrum has been used by some groups as a means to discredit altogether. In this new effort, the team in California sought to answer the question once and for all.

Their work began with the idea that vision in vertebrates may have got its start by using light-sensitive genes transferred from microbes. To find out if that might be the case, the team submitted likely human gene candidates to the IQ-TREE program to look for similar genetic sequences in other creatures, most specifically, microbes.
