Ask Slashdot: What Happens If We Perfect Age Reversing? 692

Posted by samzenpus from the mad-max-time dept.
ourlovecanlastforeve writes: With biologists getting closer and closer to reversing the aging process in human cells, the reality of greatly extended life draws closer. This brings up a very important conundrum: You can't tell people not to reproduce and you can't kill people to preserve resources and space. Even at our current growth rate there's not enough for everyone. Not enough food, not enough space, not enough medical care. If — no, when — age reversal becomes a reality, who gets to live? And if everyone gets to live, how will we provide for them?

How To Die On Mars 278

Posted by Soulskill from the get-your-coffin-to-mars dept.
An anonymous reader writes: Many space-related projects are currently focusing on Mars. SpaceX wants to build a colony there, NASA is looking into base design, and Mars One is supposedly picking astronauts for a mission. Because of this, we've been reading a lot about how we could live on Mars. An article at Popular Science reminds us of all the easy ways to die there. "Barring any complications with the spacecraft's hardware or any unintended run-ins with space debris, there's still a big killer lurking out in space that can't be easily avoided: radiation. ... [And] with so little atmosphere surrounding Mars, gently landing a large amount of weight on the planet will be tough. Heavy objects will pick up too much speed during the descent, making for one deep impact. ... Mars One's plan is to grow crops indoors under artificial lighting. According to the project's website, 80 square meters of space will be dedicated to plant growth within the habitat; the vegetation will be sustained using suspected water in Mars' soil, as well as carbon dioxide produced by the initial four-member crew. However, analysis conducted by MIT researchers last year (PDF) shows that those numbers just don't add up."

Comment For those in Power,oversimplification is the Point (Score 1) 327

by D4C5CE (#49779093) Attached to: Why PowerPoint Should Be Banned

Its slides are oversimplified, and bullet points omit the complexities of nearly any issue

So whatever split-second decision an overpaid high-level executive takes by not allowing anything the requisite minimum thought, s/he can later blame on (and get someone else fired for) having been given incomplete information as requested by demanding earlier on that every complex matter be reduced to a polished assortment of insufficient buzzwords in incomplete grammar. In short, PPTs institutionalize PHBs' hierarchical infallibility at the expense of underlings who have to use it.

Why PowerPoint Should Be Banned 327

Posted by Soulskill from the hang-on-my-clicker-isn't-working dept.
An anonymous reader writes: An editorial at the Washington Post argues that Microsoft PowerPoint is being relied upon by too many to do too much, and we should start working to get rid of it. "Its slides are oversimplified, and bullet points omit the complexities of nearly any issue. The slides are designed to skip the learning process, which — when it works — involves dialogue, eye-to-eye contact and discussions. Of course PowerPoint has merits — it can help businesses with their sales pitches or let teachers introduce technology into the classroom. But instead of being used as a means for a dynamic engagement, it has become a poor substitute for longer, well-thought-out briefings and technical reports. It has become a crutch."

Bank of England Accidentally E-mails Top-Secret "Brexit" Plan To the Guardian 396

Posted by timothy from the brexit-is-good-with-toast-and-jam dept.
schwit1 writes: The first rule of "Project Bookend" is that you don't talk about "Project Bookend." In retrospect, maybe the first rule should have been "you don't accidentally e-mail 'Project Bookend' to a news agency," because as the Guardian reports, one of its editors opened his inbox and was surprised to find a message from the BOE's Head of Press Jeremy Harrison outlining the UK financial market equivalent of the Manhattan project. Project Bookend is a secret (or 'was' a secret) initiative undertaken by the BOE to study what the fallout might be from a potential 'Brexit', but if anyone asked what Sir Jon Cunliffe and a few senior staffers were up to, they were instructed to say that they were busy investigating "a broad range of European economic issues." And if you haven't heard the term before, "Brexit" refers to the possibility of Britain leaving the EU -- one of the possible outcomes of an upcoming referendum.

NSA-Reform Bill Fails In US Senate 135

Posted by timothy from the couldn't-have-happened-to-a-nicer-bill dept.
New submitter Steven King writes with a link to The Daily Dot's report that the U.S. Senate has rejected the controversial USA Freedom Act, thus "all but guaranteeing that key provisions of the USA Patriot Act will expire"; had it passed, the bill would have allowed continued use of some mass data-collection practices, but with the addition of stronger oversight. From the article: The Senate failed to reach agreement on passage of the USA Freedom Act, a bill to reauthorize and reform Section 215 of the USA Patriot Act, which the government has used to conduct bulk surveillance of Americans' phone records. The House of Representatives passed the bill last week by an overwhelming bipartisan majority, but Senate Democrats, who unified behind the bill, did not get enough Republican votes to assure passage. The linked piece also mentions that the EFF shifted its position on this bill, after a panel of Federal judges ruled that the Feds at the NSA had overstepped their bounds in collecting a seemingly unlimited trove of metadata relating to American citizen's phone calls.

Protons Collide At 13 TeV For the First Time At the LHC 52

Posted by Soulskill from the go-big-or-go-home dept.
An anonymous reader writes to let everyone know the LHC has now smashed protons together at 13 TeV, the highest energy level yet achieved. They've posted the first images captured from the collisions, and explained the testing process as well. Jorg Wenninger of the LHC Operations team says, "When we start to bring the beams into collision at a new energy, they often miss each other. The beams are tiny – only about 20 microns in diameter at 6.5 TeV; more than 10 times smaller than at 450 GeV. So we have to scan around – adjusting the orbit of each beam until collision rates provided by the experiments tell us that they are colliding properly." Spokesperson Tiziano Camporesi adds, "The collisions at 13 TeV will allow us to further test all improvements that have been made to the trigger and reconstruction systems, and check the synchronisation of all the components of our detector."

Dunning Kruger effect in action! This, guys, is what just may have killed IBM, from me to you. I am a former IBM employee.

Remarkably, Who Says Elephants Can't Dance? demands that "dealing final blows" be praised as "saving" (short-term "rescue" entrenching the long-term demise AKA "Historic Turnaround"). The sections measuring the merits e.g. of OS/2 (and over the years, pretty much any technological asset) by the same standard as consumer packaged goods are particularly saddening.

Obama Announces e-Book Scheme For Low-Income Communities 126

Posted by samzenpus from the you-get-a-book-and-you-get-a-book-and-you-get-a-book dept.
An anonymous reader writes: The White House has today launched an initiative encouraging top book publishers to supply $250 million worth of free e-books to low-income students. Partnering with local governments and schools nationwide, President Obama hopes that the e-book scheme will support low-income households who significantly trail the national average for computer ownership and digital connectivity. At Anacostia Library in Southeast Washington, D.C., Obama announced that libraries and schools in poorer communities would be supported by the scheme and efforts would be made to increase internet access at these establishments. Publishers involved in the program include Penguin Random House, Macmillan, Bloomsbury, HarperCollins and Simon & Schuster. NGOs, such as book donation charity Firstbook, and public libraries will also be working together to develop apps to support the digital reading program.

NASA Probe Spies Possible Polar Ice Cap On Pluto 60

Posted by samzenpus from the coldest-of-the-cold dept.
astroengine writes: As NASA's New Horizons spacecraft rapidly approaches Pluto for its historic flyby in July, the dwarf planet is gradually sliding into focus. And in the latest series of observations beamed back from the fringes of the Kuiper belt, surface features are becoming evident including the stunning revelation that Pluto may possess a polar ice cap. "As we approach the Pluto system we are starting to see intriguing features such as a bright region near Pluto's visible pole, starting the great scientific adventure to understand this enigmatic celestial object," said John Grunsfeld, associate administrator for NASA's Science Mission Directorate in Washington D.C. "As we get closer, the excitement is building in our quest to unravel the mysteries of Pluto using data from New Horizons."

IBM CIO Thinks Agile Development Might Save Company 208

Posted by samzenpus from the best-laid-plans dept.
Nerval's Lobster writes: A new Wall Street Journal article details how IBM CIO Jeff Smith is trying to make Big Blue, which is going through some turbulent times as it attempts to transition from a hardware-dependent business to one that more fully embraces the cloud and services, operate more like a startup instead of a century-old colossus. His solution centers on having developers work in smaller teams, each of which embraces Agile methodology, as opposed to working in huge divisions on multi-year projects. In order to unite employees who might be geographically dispersed, IBM also has its groups leave open a Skype channel throughout the workday. Smith hopes, of course, that his plan will accelerate IBM's internal development, and make it more competitive against not only its tech-giant competition, but also the host of startups working in common fields such as artificial intelligence.

Signs of Subsurface 'Alien' Life Found In Antarctica 106

Posted by timothy from the welcome-friends dept.
astroengine writes: An airborne survey of a presumably dry Antarctic valley revealed a stunning and unexpected interconnected subsurface briny aquifer deep beneath the frozen tundra, a finding that not only has implications for understanding extreme habitats for life on Earth, but the potential for life elsewhere in the solar system, particularly Mars. The briny liquid — about twice as salty as seawater — was discovered about 200 miles underground in a region known as Taylor Valley. The aquifer is widespread, extending from the Ross Sea's McMurdo Sound more than 11 miles into the eastern part of valley. A second system was found connecting Taylor Glacier with the ice-cover Lake Bonney. But the survey, which covered 114 square miles, may have just uncovered the proverbial tip of the iceberg.
