Instead, when he analyzed the sample, he was amazed to see that primers could pull out the DNA of ancient mammoths, bison, horses and a variety of plants. Sometimes the scientists use universal primers, which recognize small sequences of DNA from all the organisms in one species or family; these molecules can then identify all the plant DNA or animal DNA to be amplified, or replicated, through the polymerase chain reaction. Jamie Wood, a paleoecologist at Manaaki Whenua Landcare Research who studies ecosystem function and composition in New Zealand over the past 50,000 years, explains that painstaking measures also have to be taken to ensure modern DNA doesn’t get mixed up in the ancient sample.

By default, the Bash shell keeps the history of your most recent session in the file, and the commands you’ve issued in your current session are also available with a call. These defaults are useful for keeping track of what you’ve been up to in the shell on any given machine, but with disks much larger and faster than they were when Bash was designed, a little tweaking in your file can record history more permanently, consistently, and usefully. To make your file a little easier to parse, you can force commands that you entered on more than one line to be adjusted to fit on only one with the option:

By default, Bash only records a session to the file on disk when the session terminates.

Person/city associations were based on the thousands of “People from X city” pages on Wikipedia. The top person from each city was determined by using median pageviews (with a minimum of 1 year of traffic). We chose to include multiple occurrences for a single person because there is both no way to determine which is more accurate and people can “be from” multiple places.

MapR Technologies Inc., one of the troika of unicorn startups that emerged from the early days of the big-data movement, may cut up to 122 jobs and shut down its Santa Clara, California headquarters if it can’t secure additional funding. MapR was one of three well-funded startups – along with Cloudera Inc. and Hortonworks Inc. — that emerged a decade ago to commercialize products and services around the open-source ecosystem around Hadoop, a popular software framework for processing huge amounts of data.

police-related data does your city publish?The Police Open Data Census, created by Code for America fellows in Indianapolis, is tracking “currently available open datasets about police interactions with citizens in the US,” including officer-involved shootings, use of force, and citizen complaints. [h/t Tom Johnson, who emailed Data Is Plural to praise how Albuquerque is sharing its data: “I have not found any other city in the world doing so in such billion pages of books (and booklike things). For each of its 1.8 billion pages, the dataset includes word frequencies, languages used, and sentence counts, among other Prussian horses.For his 1898 book, The Law of Small Numbers, statistician Ladislaus Bortkiewicz tabulated the number of Prussian cavalrymen killed by horse kicks each year between 1875 and 1894.

A Democrat-led spending panel in the U.S. House of Representatives has dropped a provision that banned embryo editing with the intention of creating a baby. It bars the Food and Drug Administration (FDA) from considering any clinical trial application “in which a human embryo is intentionally created or modified to include a heritable genetic modification.” Although a different “rider” bars the National Institutes of Health from funding human germline editing—or the genetic modification of sperm, eggs, or embryos—such work is permissible with private funding.

Here are a couple of papers I’ve looked into and I found to be enough to get the general idea: The Lattice Boltzmann Method for Fluid Dynamics: Theory and Applications, Implementation techniques for the lattice Boltzmann method. You should not stop there if you want more than this project covers, there is a lot to find out, there is a lot of work on thermal Lattice Boltzmann methods, a lot of work on boundary conditions, multi-phase flow and so on. If you want to find more about the project than the actual Lattice Boltzmann code, you might want to look first into where the image file that contains the obstacles is loaded, then into the document methods starting with and the others at the end of the cpp file implementing the document.
