Science

+ - The strange case of solar flares and radioactive e->

Submitted by
DarkKnightRadick
DarkKnightRadick writes "The case for radioactive decay has been challenged, by of all sources, the sun itself. According to the article:
"On Dec 13, 2006, the sun itself provided a crucial clue, when a solar flare sent a stream of particles and radiation toward Earth. Purdue nuclear engineer Jere Jenkins, while measuring the decay rate of manganese-54, a short-lived isotope used in medical diagnostics, noticed that the rate dropped slightly during the flare, a decrease that started about a day and a half before the flare."
This is important because the rate of decay is very important not just for antique dating, but also for cancer treatment, time keeping, and the generation of random numbers. This isn't a one time measurement, either.
"Checking data collected at Brookhaven National Laboratory on Long Island and the Federal Physical and Technical Institute in Germany, they came across something even more surprising: long-term observation of the decay rate of silicon-32 and radium-226 seemed to show a small seasonal variation. The decay rate was ever so slightly faster in winter than in summer.""

+ - Life In 2010

Submitted by
DarkKnightRadick
DarkKnightRadick writes "First, I would like to thank TheRealGrogan for this comment. Without it I'd still not have a fully updated and patched system. Stupid Windows.

So life in 2010 is going pretty good. On September 1st I start classes at TTCM in their industrial electricity program. Some people (here on /. none-the-less) look at this with some sort of derision, either because of my age or choice of training program. I could easily go into industrial electronics too, but I figure it's no good if you have no electricity.

Why is any trade looked upon with derision (aside from the criminal trades and prostitution), though? Especially here, where one would think that continuing education — no matter where that leads — would be looked upon as a good thing.

Life is good in 2010 so far, let's see how the rest of the year pans out."

+ - Supermassive black hole is thrown out of galaxy->

Submitted by
DarkKnightRadick
DarkKnightRadick writes "An undergrad student at the University of Utrecht, Marianne Heida, has found evidence of a super massive black hole being tossed out of it's galaxy. According to the article, the black hole — which has a mass equivalent to 1 billion suns — is possibly the culmination of two galaxies merging (or colliding, depending on how you like to look at it) and their black holes merging, creating one supermassive beast. The black hole was found using the Chandra Source Catalog (from the Chandra X-Ray Observatory). The direction of the expulsion is also possibly indicative of the direction of rotation of the two black holes as they circled each other before merging. The story can also be found here."

+ - QUT physicist corrects Oxford English Dictionary (->

Submitted by
DarkKnightRadick
DarkKnightRadick writes "Dr. Stephen Hughes, a Queensland University of Technology physics lecturer, has discovered an error in the Oxford English Dictionary that has apparently been there since 1911 and has made it's way to every other dictionary in existence. The error, which defines a siphon as working on the principle of atmospheric pressure, was discovered as Dr. Hughes was getting ready to write an article about siphons after viewing the one at Lake Bonney (mis-spelled in the article). Dr. Hughes' article(pdf) — practical example of a siphon at work — is ready for viewing (along with a correct spelling of the Lake's name)."

Submitted by
DarkKnightRadick
DarkKnightRadick writes "According to this article on PhysOrg.com, the ancient Mayans had pressurized plumbing as early as sometime between the year 100 (when the city in question was first founded) and 800 (when it was abandoned). While the Egyptians had plumbing way earlier (around 2500BC according to this site), this is the first instance of plumbing in the New World prior to European exploration and conquering."

Submitted by
DarkKnightRadick
DarkKnightRadick writes "Most of you who use twitter apps know that there is a rate limit to the API so as not to flood the Twitter servers. Well an article just up on Mashable reveals that Twitter is about to do away with rate limits completely:

The new API is focused around pushing out data to desktop applications in real time. There will no longer be rate-limits for data on desktops — tweets, retweets and all other updates will be streamed directly to the desktop.
