  1. APoD has had better light echoes on Echoes from Ancient Supernovae Found? · · Score: 2, Interesting

    The significance of this particular story is that a thin, attenuated light echo was used to locate a supernova that is no longer visible. APOD has had far more spectacular light echoes but usually you can plainly see the primary source of the echo at the center since they are only a few years old. In this case the echoes they found were hundreds of years old- thin expanding rings of reflected light hundreds of light years in diameter- with centers that were completely dark. The echoes were only found serendipitously using digital image processing during a search for something else (dark matter).

    While it wasn't a supernova, the January 2002 flash from star V838 Monocerotis in the Milky Way made a nice, photogenic light-echo quite recently. The star, its flash, and the subsequent light echo are interesting for several reasons:

    1. The reason for the flash remains unexplained by theory, and the star has been posing problems for theorists ever since. Stars that make problems for theorists are always interesting.
    2. Although the flash was not a supernova, it made V838 Mon the brightest star in the entire Milky Way for a few days. The star's normal intensity was about 1 Sun, but at its peak the brightness was equivalent to 600,000 Suns. (For comparison, Rigel shines with the light of 40,000 Suns, and Deneb, one of the most powerful Milky Way stars known, shines with the light of up to 250,000.) But the flash was not a supernova (not bright enough) nor a nova since the star did not lose its outer envelope. The star swelled to a huge size (it would have reached the radius of Jupiter's orbit) and remained cooler at its surface than it had been before the flash.
    3. The star has a lot of interstellar dust surrounding it for light-years in every direction, which makes for good pictures as the light-echo from the flash widens and illuminates successive rings of dust around the star. (In any light-echo the rings are circular paraboloids, really, centered around the star-earth line, with the star at the focus of the paraboloid. The light echo you see is effectively reflecting off a huge "parabolic mirror" made of dust and pointing at you.)
    4. V838 Mon is in the Milky Way (only 20000 light years distant) so we can get better pictures of its light echo than the light echos associated with any recent supernovas. (The closest recent supernova was SN1987A and that was in the LMC, not the Milky Way.) People discovered this thing only a few days after it happened and we now have a sequence of very nice shots covering it at all times starting at the very beginning of the echo.

    V838 Mon has been featured on APOD eight times since 2002. Its light echo is now 8 years in diameter and is still vividly lighting up successive rings of crap in the vicinity of the star. There are many animations of the echo on the web but look for the more newer ones since they have more frames that include observations from 2004-2005.

    No widely accepted theory has succeeded in explaining the exact mechanism that caused the flash but astronomers generally agree that V838 Mon is a member of a new class of variable star that has been seen only twice before: M31-RV, a red variable in Andromeda that had a flash in 1989, and V4332 Sagittari, a red giant in Sagittarius that flashed in 1994. Current ideas include both cannibalism of a binary companion and planet swallowing.

    There used to be one on our street like that (in NJ). Its opening was announced every year in the newspapers and in the churches, and people would come from miles away to parallel park in front of our driveways. We called it "The Monstrosity". This guy had an entire "winter wonderland" in his backyard with a lighted path that you would walk around in. Everything was there- primitive animatronics, blinking colored lights of all sorts, and hundreds of hand-painted plywood cutouts of elves and Snow White and the seven dwarves and Bambi and various other Disney characters (recycled from school plays at the local Catholic schoool I think). There was a life size talking Santa at the beginning of the lighted path telling people to enjoy themselves and stay on the path as they went through, and at the end of the path there was a GIFT SHOP in his basement to defray his electric bill I guess since they weren't charging admission.

    I don't live in that neighborhood anymore but my parents say it stopped in recent years since the guy was starting to get too old for it.

    Bullshit. (I put bold tags around the part of your argument that is presupposing a conviction or an omniscient chief executive.) If this were the case then they could just use a FISA or Title III warrant.

    This is not an investigation into "known terrorist-affiliated US citizens" who are dialing Bin Laden's cellphone.

    And we're starting to see FISA judges resigning in protest as the NSA program has tainted the warrants granted by the FISA court.
    Revelation of the program last week by the New York Times also spurred considerable debate among federal judges, including some who serve on the secret FISA court. For more than a quarter-century, that court had been seen as the only body that could legally authorize secret surveillance of espionage and terrorism suspects, and only when the Justice Department could show probable cause that its targets were foreign governments or their agents.

    Robertson indicated privately to colleagues in recent conversations that he was concerned that information gained from warrantless NSA surveillance could have then been used to obtain FISA warrants. FISA court Presiding Judge Colleen Kollar-Kotelly, who had been briefed on the spying program by the administration, raised the same concern in 2004 and insisted that the Justice Department certify in writing that it was not occurring.

    "They just don't know if the product of wiretaps were used for FISA warrants -- to kind of cleanse the information," said one source, who spoke on the condition of anonymity because of the classified nature of the FISA warrants. "What I've heard some of the judges say is they feel they've participated in a Potemkin court."

    I bought a used 2001 Prius in great shape earlier this year for $13k (60k miles). It was being sold on Craigslist by a couple who were trading up to a newer model.

    I seriously doubt the tribrid idea would fly... electric-drive hybrids run off batteries most of the time with the combustion engine kicking off only during strong-ish accelerations or when the batteries go below a certain point. Most of the time, the gas engine would not run long enough to release enough heat and generate usable amounts of steam.

    This sounds completely backwards, at least for Priuses. The engine is on virtually all the time. It decides to turn itself off at red lights and in parking garages when I'm going 10 mph, but most of the time it's running at a stable rpm that doesn't change too much. During the first 5 minutes the car is in its warmup phase and I get 30 mpg, but after that I get 50. On the highway, the car is basically just powered by the engine alone. When I accelerate to pass somebody it uses the battery to assist.

    The whole point is to buffer power output from the primary power source (the engine) so you can get the same performance from a smaller one. Energy is stored in the battery during times it's not needed and drawn from it during hard accelerations. The engine is decoupled from the constantly changing power demand- it runs at a relatively stable and efficient rpm and produces a relatively stable torque no matter what you're doing unless the computer decides to turn it off. A steam engine run on exhaust heat would be a great addition to a Prius.

A negative position indicates that the reported alleles are relative to the compliment strand. (This happens if they get the strand wrong when they define it.)

The locus in question is either one of these 66, or else the "smart/dumb" gene is a splice variant which is also likely- one of the versions has an exon that the other doesn't- which would mean that the locus is in a promoter region in one of the 47 introns. There are 603 variations in the introns. That would never get past the lameness filter.

    The popularized crap on Google News is useless. I did a search on Google Scholar for "IGF2R Jirtle IQ" and found this:

    Interestingly, M6P/IGF2R in mice is imprinted in all tissues except for the brain where both alleles are expressed. It is highly expressed in neurons of the forebrain, with the highest expression in the pyramidal cells, the polymorphic layers of the hippocampus, and the granule cell layer of the dentate gyrus; regions involved in emotional behavior, information processing, and memory formation. These findings indicate that M6P/IGF2R may assist in the development of these brain functions. This postulate is reinforced by the identification of M6P/IGF2R as the first putative "IQ gene." By comparing children with an IQ of 160 or higher to those with an average IQ, M6P/IGF2R was shown to be linked with general cognitive ability ("g"). The role of this receptor in the development of cognitive function can now be systematically assessed with M6P/IGF2R conditional knockout mice.
