  1. DNA reading/righting rather slow on Researchers Achieve Storage Density of 2.2 Petabytes Per Gram of DNA · · Score: 1

    Its like a millisecond per base pair or a kilobyte or two per second. However a cell may have tens of thousands of ribosomes to parallelise this function.

  2. Kneau Reeves movie "Johnny Mnemonic" on Researchers Achieve Storage Density of 2.2 Petabytes Per Gram of DNA · · Score: 0

    The download data into Kneau's head as a courier. However I think they spoke of "gigabytes" back in 1995.

  3. 93 million miles on Earth May Have Been Hit By a Gamma-Ray Burst In 775 AD · · Score: 2

    I've heard the 775 C14 anomaly attributed to a very large solar storm period too, even those these guys dismiss the idea.

  4. we've been shipping java supercomputing apps on Java Vs. C#: Which Performs Better In the 'Real World'? · · Score: 1

    for a decade to the oil/seismic industry. 17 years ago we thought we might need to delegate number-crunching loops to C++/C/FORTRAN. But that has proved unnecessary. Java integrates parameter control, graphic GUIs, and debugging. I cringe when I have to maintain some old C++ stuff. 64-bit JVMs have been a godsend, since we routinely create 100GB heaps. We've supported Java on IBM, Sun and Windows platforms. 64-bit Linux on workstations and clusters is the plaform de-jour.

  5. 60 mutations in germ cells on Researchers Study Mystery of the Toddler Who Won't Grow · · Score: 1

    They've enough comparison of parental chromosomes to tell there are about 30 random gene mutations inherited from each parent. They'll have to sort for these whether there is one or more on a significant gene.

  6. I notice Nature has "sponsored papers" on The Atlantic's Scientology Advertorial · · Score: 1

    Nature is supposedly on of the most respected science journals around (even if you deconstruct the liberal bias in its comments section). Even once in a while they run theme sections of either assembled or invited papers. And I noticed in two such recent sections there is a sponsored article from an industrial source. The paper is clearly labeled as sponsored. An example is a special section on COPD. A drug company published a study about a drug to deal with this. (Was that the one with elephant tv commercial?). I assume the sponsored paper has the same editorial scrutiny as the other articles. But I wonder.

  7. is there a reference to Earth at all in Star Wars? on The Empire Writes Back About the Failed Death Star Petition · · Score: 2

    Other than it was long ago and far away. A couple Star War stars have the same names as our stars.

  8. not first on Curiosity Finds Evidence of Ancient Surface Water · · Score: 1

    They announced finding rounded stream gravel a few weeks ago. Other fossil water traces would not be a surprise then.

  9. c is abbreviation for velocity in Latin on Students Calculate What Hyperspace Travel Would Actually Look Like · · Score: 1

    "celeritius" is velocity in Latin. Scientists used to write mostly in Latin until the 1800s.

  10. culled some of the best of NASA too on Inside the Tech of SpaceX's Homegrown Rocket Engine · · Score: 2

    SpaceX is supposed have about 10-20% ex-NASA people, mainly younger folk. Dont think of NASA as automatically bloated - it was the only game for aspiring rocket scientists before the 2000s. Recycling NASA people preserves some of their experience. One of the problems with the Orion program is that a lot of the good Apollo ideas had been lost due to retirement of those engineers and loss of record.

  11. "maker" sweet spot 10 - 1000 copies on 3D Printable Ammo Clip Skirts New Proposed Gun Laws · · Score: 1

    Less than 10 copies you may want to machine it yourself. More than a thousand, you may want to make a die and outsource it.

  12. you get to use 100% of volume in micro-gravity on NASA Awards Contract To Bigelow Aerospace For Inflatable ISS Module · · Score: 1

    On earth 6 foot ceiling is not all that much different than a 20-foot ceiling, because you arent going to use much of that space above 6 feet. But in micro-gravity you any of the six walls becomes a floor, thereby allowing you to use the entire volume. Less claustophobic in that case.

  13. suicide is a significant problem at MIT on MIT Investigating School's Role In Swartz Suicide · · Score: 4, Interesting

    Understanding why hackers do this may prevent some future suicides anywhere in the hacker community.

    Up to a half dozen students commit suicide any year. Several large lawsuits from the parents of suicide victims in the past decade prompted MIT to beef up round-the-clock mental health care help. Most recently the MIT student newspaper conducted and extensive study of stress in student life. Its almost like coming out gay- plenty of students think they are the only ones suffering from stress and retreat into their personal hell-holes. The need to talk to each other and professionals.

  14. unstable personality made him great programmer on US Attorney Chided Swartz On Day of Suicide · · Score: 1

    All those wonderful project he did like RSS and free software. However, I fear it may have made less able to stand the fearful pressure of federal prosecution hardball. Its not your routine traffic ticket.

  15. GM IT is contrarian (maybe right) on GM CIO Says HP Hiring Probe "Not the Best Use Our Legal System" · · Score: 1

    GM was one of the first large companies to outsource most of its IT when it divested its IT to Hughes Electronics in the 1980s. (EDS acquired Hughes; HP acquired EDS) Many other companies the did the same. Now GM is one of the first large companies to insource back these operations.

  16. movie "Contagion" realistic depiction on Boston Declares Health Emergency Due To Massive Flu Outbreak · · Score: 1

    The 2011 movie Contagion was a little better than your standard apocalyptic movie in showing how a serious epidemic could bring down the world in about a month. Many similar movies like Outbreak and Andromeda Strain have deus-ex-machina endings of a quickie cure. But that is unlikely to be the case. Humanity has passed through anvil-type events before- plague, war, famine- where as many as 90% have perished. We've been lucky in modern society to have avoided these for so long.

  17. derived standard based upon volt on Standard Kilogram Gains Weight · · Score: 1

    They know the volt to a high decimal precession in Josephson junction. There are equations that can convert a volt into a mass.

    Planck's mass has been proposed too. But we dont know the unit of action to enough decimal places.

    The most accurate measurement is the unit of time from atomic excitation in lasers. Thats 14 to 18 decimal places. You have to start taking account of the two kinds of relativities around the 9th decimal place etc. The volt measurement bootstraps off of this.

    Physics Today used to publish a quadrennial report on the the "state of the constants". This included revisions from experiment. And research on improvements. Fascinating reading.

  18. four US "standard kilos" compared 24 years ago on Standard Kilogram Gains Weight · · Score: 1

    The variance was one part in 20 million - well within modern measurement error. Probably about 22-25 million by now as they continued to diverge withing their individual environments.

  19. keystroke timings are fingerprint on Linguistics Identifies Anonymous Users · · Score: 1

    There are tiny timing differences as one types. these are quite distinctive between individuals if you collect enough data. Its related to how an individual learns type; Motor memory of word-phrases versus typing a new word for the first time. Even the pattern of common typing errors and recovery.

  20. a lot easier when I got into one of those on Best Tech Colleges Are Harder Than Ever To Get In · · Score: 3, Interesting

    About 25% acceptance rate when I got into MIT decades ago. But then applying to more than 3-4 colleges was unusual. Computers/Internet make it somewhat easier to churn applications now. So with twice as many people applying to college at three times more college since then increases applications around six-fold.

  21. half dozen who've spent year in space already on Trip To Mars Could Damage Astronauts' Brains · · Score: 1

    Three who've spent all at one time. I wonder if they've noticed any problems with those astronauts. I believe next year there will be two people who stay on the ISS for a full year to update medical knowledge.

  22. charges US astronauts a billion a launch? on Russian Space Industry To Receive $69 Billion Through 2020 · · Score: 1

    They already charge US astronauts 3x ($60M) per launch seat compared to ($20M) for space tourists like Sarah Brightman. The US screwed by terminating its viable shuttle program without a replacement for at least 8 years.

  23. neither party likes them much on NASA Faces Rough Road In 2013 · · Score: 1

    Despite all the campaign rhetoric. The dems want more social spending. The repubs want more privatisation. NASA is a sitting duck in being fairly large.

  24. content pricing, not hardware is the problem on Intel's Rumored TV Plans Would Compete With Apple, Google · · Score: 1

    Right now you have to buy a huge of channels (and shows) to get the 20 hours you might want to watch each month. Or you have to do delayed broadcasts (not good for sports & news) or pirate to get the individual shows.

  25. Jaron's a long time iconoclast on What Turned VR Pioneer Jaron Lanier Against the Web · · Score: 2

    My first live Jaron talk was a rant against virtual reality at Xerox Parc in the 1980s. The VC's were exploring it as the Next Great Thing. Jaron had done some experimenting and found it lacking then.

    He does think about things deeply. So I value his comments even if I do not always agree.
