  1. DNA Research Shows Canaanites Were Not Wiped Out By Israelites BY DANIELA COBOS ON 07/28/17 AT 4:51 PM A study published Thursday found that the ancient Canaanites were not destroyed by the Israelites as the Bible says, but rather that they went on to become modern-day Lebanese. In a study conducted by the American Journal of Human Genetics, UK’s Wellcome Trust Sanger Institute sent researchers to extract DNA from remains of five people found in the former Canaanite city state of Sidon, a coastal city in Lebanon. The remains were estimated to be 3,700 years old. The ancient Canaanites lived in the cities Sodom and Gomorrah, which were reportedly destroyed by God, according to the Book of Genesis. The Old Testament Book of Deuteronomy said God told the Israelites to wipe out the Canaanites. “Do not leave alive anything that breathes. Completely destroy them otherwise they will teach you to follow all the detestable things they do in worshipping their gods, and you will sin against the Lord your God,” he said to the Israelites. Despite this passage, other parts of the Bible contradicted the idea that the Israelites exterminated all of the Canaanites, suggesting there may have been survivors. Researchers examined the entire genome of the nearly 4,000-year-old remains and compared it to the DNA of 99 modern Lebanese people. They determined that more than 90 percent of modern-day Lebanese ancestry could be traced back to the Canaanites. “The Bible reports the destruction of the Canaanite cities and the annihilation of its people; if true, the Canaanites could not have directly contributed genetically to present-day populations,” the study read. “However, no archaeological evidence has so far been found to support widespread destruction of Canaanite cities between the Bronze and Iron Ages. We show that present-day Lebanese derive most of their ancestry from a Canaanite-related population, which therefore implies substantial genetic continuity in the Levant since at least the Bronze Age.” Dr. Marc Haber, one of the researchers from the Wellcome Trust Sanger Institute, said it was a “pleasant surprise” to analyze 3,700-year-old DNA found in a hot environment. “The present-day Lebanese are likely to be direct descendants of the Canaanites, but they have in addition a small proportion of Eurasian ancestry that may have arrived via conquests by distant populations such as the Assyrians, Persians, or Macedonians,” he said. The Canaanites are credited with introducing what is believed to be the first alphabet during the Bronze Age. http://www.ibtimes.com/dna-research-shows-canaanites-were-not-wiped-out-israelites-2571963
  2. Scientists replay movie encoded in DNA “Molecular Recorder” would reveal secrets of brain development. For the first time, a primitive movie has been encoded in — and then played back from — DNA in living cells. Scientists funded by the National Institutes of Health say it is a major step toward a “molecular recorder” that may someday make it possible to get read-outs, for example, of the changing internal states of neurons as they develop. “We want to turn cells into historians,” explained neuroscientist Seth Shipman, Ph.D.(link is external), a post-doctoral fellow at Harvard Medical School, Boston. “We envision a biological memory system that’s much smaller and more versatile than today’s technologies, which will track many events non-intrusively over time.” Shipman, Harvard’s Drs. George Church(link is external), Jeffrey Macklis(link is external) and Jeff Nivala(link is external)report on their proof-of-concept for a futuristic “molecular ticker tape” online July 12, in the journal Nature. The work was funded by NIH’s National Institute of Mental Health, National Institute of Neurological Disorders and Stroke, and the National Human Genome Research Institute. The ability to record such sequential events like a movie at the molecular level is key to the idea of reinventing the very concept of recording using molecular engineering, say the researchers. In this scheme, cells themselves could be induced to record molecular events – such as changes in gene expression over time – in their own genomes. Then the information could be retrieved simply by sequencing the genomes of the cells it is stored in. “If we had those transcriptional steps, we could potentially use them like a recipe to engineer similar cells,” added Shipman. “These could be used to model disease – or even in therapies.” For starters, the researchers had to show that DNA can be used to encode not just genetic information, but any arbitrary sequential information into a genome. For this they turned to the cutting-edge, NIH-funded gene editing technology CRISPR. They first demonstrated that they could encode and retrieve an image of the human hand in DNA inserted into bacteria. They then similarly encoded and reconstructed frames from a classic 1870s race horse in motion(link is external) sequence of photos – an early forerunner of moving pictures. The researchers had previously shown that they could use CRISPR to store sequences of DNA in bacteria. CRISPR is a group of proteins and DNA that act as an immune system in some bacteria, vaccinating them with genetic memories of viral infections. When a virus infects a bacterium, CRISPR cuts out part of the foreign DNA and stores it in the bacteria’s own genome. The bacterium then uses the stored DNA to recognize the virus and defend against future attacks. “The sequential nature of CRISPR makes it an appealing system for recording events over time,” explained Shipman. The researchers then similarly translated five frames from the race horse in motion photo sequence into DNA. Over the course of five days, they sequentially treated bacteria with a frame of translated DNA. Afterwards, they were able to reconstruct the movie with 90 percent accuracy by sequencing the bacterial DNA. Although this technology could be used in a variety of ways, the researchers ultimately hope to use it to study the brain. “We want to use neurons to record a molecular history of the brain through development,” said Shipman. “Such a molecular recorder will allow us to eventually collect data from every cell in the brain at once, without the need to gain access, to observe the cells directly, or disrupt the system to extract genetic material or proteins.” GRANTS: MH103910, NS045523, HG005550 About the National Institute of Mental Health (NIMH): The mission of the NIMH is to transform the understanding and treatment of mental illnesses through basic and clinical research, paving the way for prevention, recovery and cure.

  3. Salam What is Our real Scientic Ancestory. Nice brief 5 min watch at the expressions people have when their results are shown:
  4. Do you think it is Haram to bring back an Extinct Animal such as the wolly mammoth which is looking to be more of a possibility. Have our Ayatollah's discussed such a topic? DNA of a Wolly Mammoth has already been merged with an Elephants: http://www.telegraph.co.uk/news/science/science-news/11488404/Woolly-mammoth-could-roam-again-as-extinct-DNA-merged-with-elephant.html Could we use this method to save the different species of soon to be extinct animals.
