      • There's a Huge Problem With the Core of the Human Genome Project

        "The model needs to change.”

        ...
        The Human Genome Project, which began in the 1990s, was Homo sapiens’ successful attempt to map out the entirety of our species’ DNA. It produced the human reference genome, a finely polished collection of human DNA that’s crucial for genetics research and genetics testing services around the world. Integral as it has been to the science community, two researchers at Johns Hopkins University have discovered that the reference genome is missing a piece or two — well, 296,485,284 base pairs of DNA, to be exact.

        The reference genome is an essential map of human genetic material that is used as a basis for comparison. When we sequence our own DNA for insight into health, family history, and future disease risk, we chop up the sequence into lots of little pieces and compare stretches of it to the reference genome, looking for areas where we differ. The fundamental problem with this, the scientists write in a recent paper in Nature Genetics, is that the reference genome is based largely on a single person. Considering the myriad genetic differences among the 7.7 billion people alive today, that’s obviously not ideal.

        Professor of computer science and biostatistics Steven Salzberg, Ph.D., and Rachel Sherman, a Ph.D. candidate, make the case that this single reference genome doesn’t capture the diversity of human genetics. Some populations, they add, differ too much from this reference genome. To make their case, they refer to the genomes of 910 individuals from twenty different countries, all of pan-African descent.

          Broken and scorched black by fire, the dense, wedge-shaped marks etched into the ancient clay tablets are only just visible under the soft light at the British Museum. These tiny signs are the remains of the world’s oldest writing system: cuneiform.

          Developed more than 5,000 years ago in Mesopotamia, the land between the Tigris and Euphrates rivers where modern-day Iraq now lies, cuneiform captured life in a complex and fascinating civilisation for some three millennia. From furious letters between warring royal siblings to rituals for soothing a fractious baby, the tablets offer a unique insight into a society at the dawn of history.

          They chronicle the rise of fall of Akkad, Assyria and Babylonia, the world’s first empires. An estimated half a million of them have been excavated, and more are still buried in the ground.

          However, since cuneiform was first deciphered by scholars around 150 years ago, the script has only yielded its secrets to a small group of people who can read it. Some 90% of cuneiform texts remain untranslated.

          That could change thanks to a very modern helper: machine translation.

              • Earth is missing a huge part of its crust. Now we may know why.

                ...
                The Grand Canyon is a gigantic geological library, with rocky layers that tell much of the story of Earth’s history. Curiously though, a sizeable layer representing anywhere from 250 million years to 1.2 billion years is missing.

                Known as the Great Unconformity, this massive temporal gap can be found not just in this famous crevasse, but in places all over the world. In one layer, you have the Cambrian period, which started roughly 540 million years ago and left behind sedimentary rocks packed with the fossils of complex, multicellular life. Directly below, you have fossil-free crystalline basement rock, which formed about a billion or more years ago.

                So where did all the rock that belongs in between these time periods go? Using multiple lines of evidence, an international team of geoscientists reckons that the thief was Snowball Earth, a hypothesized time when much, if not all, of the planet, was covered in ice.

                According to the team, at intervals within those billion or so years, up to a third of Earth’s crust was sawn off by Snowball Earth’s roaming glaciers and their erosive capabilities. The resulting sediment was dumped into the slush-covered oceans, where it was then sucked into the mantle by subducting tectonic plates. (Here’s what will happen when Earth’s tectonic plates grind to a halt.)

                Effectively, in many locations, Earth buried the evidence of about a fifth of its geological history, the team argues today in the Proceedings of the National Academy of Sciences. The notion is elegant but provocative, and the authors themselves predict that some geoscientists will express skepticism.

                • Something Else Instead of Planet Nine Could Be Hiding in The Outer Solar System

                  ....
                  MICHELLE STARR
                  21 JAN 2019




                  Somewhere in the outer reaches of the Solar System, beyond the orbit of Neptune, something wonky is happening. A few objects are orbiting differently from everything else, and we don't know why.



                  A popular hypothesis is that an unseen object called Planet Nine could be messing with these orbits; astronomers are avidly searching for this planet. But now physicists have come up with an alternative explanation they think is more plausible.

                  Instead of one big object, the orbital wobblies could be caused by the combined gravitational force of a number of smaller Kuiper Belt or trans-Neptunian objects (TNOs). That's according to astrophysicists Antranik Sefilian of the University of Cambridge in the UK and Jihad Touma of the American University of Beirut in Lebanon.

                  If it sounds familiar, that's because Sefilian and Touma are not the first to think of this idea - but their calculations are the first to explain significant features of the strange orbits of these objects, while taking into account the other eight planets in the Solar System.

                  A hypothesis for Planet Nine was first announced in a 2016 study. Astronomers studying a dwarf planet in the Kuiper Belt noticed that several TNOs were "detached" from the strong gravitational influence of the Solar System's gas giants, and had weird looping orbits that were different from the rest of the Kuiper Belt.

                  But the orbits of these six objects were also clustered together in a way that didn't appear random; something seemed to have tugged them into that position. According to modelling, a giant, heretofore unseen planet could do so.

                  https://youtu.be/Ih22b1Qa8r0

                  So far, this planet has remained elusive - not necessarily odd, since there are considerable technical challenges to seeing a dark object that far away, especially when we don't know where it is. But its evasiveness is prompting scientists to seek alternative explanations.

                  "The Planet Nine hypothesis is a fascinating one, but if the hypothesised ninth planet exists, it has so far avoided detection," Sefilian said, adding that the team wanted to see if there was a less dramatic explanation of the weird TNO orbits.

                              • This Is the Oldest Age You Can Possibly Live To (According to Science)

                                ...
                                Human life expectancies have gone up over the years. But, according to new research, our average maximum age ceiling hit a plateau decades ago.

                                It’s no secret that humans have gotten really good at living longer. We know to eat right, to exercise, to take our vitamins, and to get our nightly eight hours. (And that doesn’t even account for the striding advancements modern medicine has made.) But no matter how smart way go about our quest for immortality, there’s only so far we can go.

                                According to a new study published in Nature—led by John Einmahl of Tilburg University and Laurens de Haan of the Erasmus University Rotterdam—the human “age ceiling” is approximately 114.1 years for men and 115.7 years for women. (The discrepancy between the genders could be explained by the fact that testosterone has been linked to shorter lifespans.)
                                ...
                                As of this writing, Einmahl and de Haan’s research has yet to be peer-reviewed, but its findings appear to be bolstered by a similar study from last year: Researchers at the Albert Einstein College of Medicine found that the average maximum age is 115.
