    The ancestors of all modern humans split off from a mystery population 1.5 million years ago and then reconnected with them 300,000 years ago, a new genetic model suggests. The unknown population contributed 20% of our DNA and may have boosted humans' brain function...In a study published Tuesday (March 18) in the journal Nature Genetics, researchers presented a new method of modeling genomic data, called "cobraa," that has allowed them to trace the evolution of modern humans (Homo sapiens).By applying their new method to modern human DNA data published in the 1000 Genomes Project and the Human Genome Diversity Project,...

    The modern potato exists thanks to a 9-million-year-old hybrid between tomato-like and potato-like plants. Credit: Shutterstock ========================================================================== Scientists have finally uncovered the ancient secret behind the potato’s origin—and it involves an unexpected genetic romance. About 9 million years ago, a wild interbreeding event occurred between a tomato-like plant and a potato-relative in the Andes. This rare hybridization gave rise to the first tuber-forming plants. Ancient Hybrid Sparked the Potato’s Origins An international team of scientists has discovered that the modern potato originated from a natural crossbreeding event between tomato plants and potato-like wild species in South America around 9 million...
  • Neanderthal DNA may refute 65,000-year-old date for human occupation in Australia, but not all experts are convinced

    ...archaeological evidence at one site called Madjedbebe in the far north of Australia's Northern Territory suggests the area may have been occupied much earlier -- at least 65,000 years ago.Archaeologists recovered human-made artifacts, including stone tools and ocher "crayons," from the Madjedbebe rock shelter and published their findings in a 2017 study. One difficulty in dating the artifacts, however, was the copious amount of sand on the floor of the rock shelter, which can move easily and cause artifacts to fall farther down, making them look older than they are.Although the research team took steps to counteract this issue and...

    A 4-year-old boy who was found dead in Lorton, Virginia, more than 50 years ago, and whose name has remained a mystery, has finally been identified after a flood of tips, a series of DNA tests and decades of twists and turns. Fairfax County police Chief Kevin Davis announced the breakthrough Monday, saying the child’s identification has led police to two people who are believed to have been involved in his killing, and another missing boy whose body has never been discovered. The case of the boy, identified as 4-year-old Carl Matthew Bryant, confounded police and the public for decades....

    Genetic evidence links Jews to their ancient tribe By Judy SiegelJERUSALEM (November 20) - Genetic evidence continues to provide additional proof to the claims that the Jewish people are descended from a common ancient Israelite father: Despite being separated for over 1,000 years, Sephardi Jews of North African origin are genetically indistinguishable from their brethren from Iraq, according to The Hebrew University of Jerusalem. They also proved that Sephardi Jews are very close genetically to the Jews of Kurdistan, and only slight differences exist between these two groups and Ashkenazi Jews from Europe. These conclusions are reached in an ...

    When the well-preserved body of the famous Ötzi the Iceman was recovered from the ice in the Austrian-Italian Alps in 1991, his remains provided archaeologists with a wealth of information about life in Europe more than 5,000 years ago. Surprisingly, sequencing of his genome indicated that he shared a very high proportion of his ancestry with early farmers who lived in Anatolia. Science News Today reports that a groundbreaking new study analyzed the DNA of 47 other individuals who lived alongside Ötzi in the Austrian Tyrol between 6400 and 1300 b.c. to determine if they shared genomic similarities. The research...

    Police have arrested a 67-year-old man in connection with the death of a woman over 30 years ago. Shona Stevens, 31, was found badly injured on a footpath in a wooded area near to the rear of Alder Green in the Bourtreehill Park area of Irvine on Thursday, November 10, 1994 and died later in hospital. The police investigation was hampered after vital evidence from the crime scene was feared to have been blown away by the downdraught of the helicopter ­airlifting Shona to hospital in Glasgow. Shona sadly died three days later after sustaining serious head injuries. Five weeks...

    Human remains found near an archaeological site in the Guatemalan jungle are thought to be those of a US birdwatcher who was reported missing almost two and a half years ago, local officials say. A lilac shirt, sandals and shorts which match those worn by Raymond Vincent Ashcroft the day of his disappearance were found at the same location where the human bones were discovered, Carlos Soza of the attorney-general's office said. Ashcroft, 66, was part of a birdwatching group visiting the ancient Maya city of Tikal... ... Human bones and clothes matching those worn by Ashcroft were spotted in...

    What does it really mean to have German ancestry? If you’ve taken a DNA test and seen the "Germanic" label, your story is far richer, older, and more dynamic than any single result. Groundbreaking genetic research reveals that Germans descend from a tapestry of Ice Age hunters, early farmers, horse-riding steppe migrants, Celtic warriors, and global travelers. Each left its enduring mark, blending survival, innovation, and migration into the DNA of modern Germans.

    Zebrafish possess a natural superpower that humans lack: the ability to regrow the tiny inner ear cells that are essential for hearing and balance. Scientists have now identified two specific genes responsible for this remarkable regeneration. These genes each control a different type of support cell, helping maintain a steady supply of stem cells while triggering the growth of new hair cells. By decoding this dual mechanism, researchers hope to uncover why humans can’t do the same—and whether we might someday flip the biological switch that restores lost hearing. Why Humans Can’t Regrow Sensory Cells Although the human body can...

    Abstract: Ancient Egyptian society flourished for millennia, reaching its peak during the Dynastic Period (approximately 3150–30 bce). However, owing to poor DNA preservation, questions about regional interconnectivity over time have not been addressed because whole-genome sequencing has not yet been possible. Here we sequenced a 2× coverage whole genome from an adult male Egyptian excavated at Nuwayrat (Nuerat, نويرات). Radiocarbon dated to 2855–2570 cal. bce, he lived a few centuries after Egyptian unification, bridging the Early Dynastic and Old Kingdom periods. The body was interred in a ceramic pot within a rock-cut tomb1, potentially contributing to the DNA preservation. Most...

    A new drug prevents weight gain and fatty liver by controlling magnesium in cells. It made mice stay slim despite lifelong exposure to an unhealthy diet. Credit: Stock Scientists have unveiled a small-molecule drug that blocks weight gain and liver damage in mice forced to live on sugary, high-fat food. The compound works by limiting magnesium inside mitochondria—the cell’s power plants—so energy keeps burning instead of stalling. Treated mice quickly slim down and show no signs of fatty-liver disease, hinting at a future therapy against obesity, heart trouble, and cancer tied to poor diets. Breakthrough Drug Fights Fat and Liver...
