Submission + - Solution To Dark Matter Proposes That Gravity Is An Illusion (forbes.com)

turkeydance writes: well, yes, the article is from Forbes:

As dark matter continues to vex astronomers, new solutions to the dark matter question are proposed. Most focus on pinning down the form of dark matter, while others propose modifying gravity to account for the effect. But a third proposal is simply to remove gravity from the equation. What if the effects of gravity aren’t due to some fundamental force, but are rather an emergent effect due to other fundamental interactions? A new paper proposes just that, and if correct it could also explain the effects of dark matter.

Submission + - Australian 'Bitcoin Founder' Quietly Bidding For Patent Empire (reuters.com)

An anonymous reader writes: Craig Wright, the Australian who claimed to be the inventor of bitcoin, is attempting to build a large patent portfolio around the digital currency and technology underpinning it, according to associates of his and documents reviewed by Reuters. Since February, Wright has filed more than 50 patent applications in Britain through Antigua-registered EITC Holdings Ltd, which a source close to the company confirmed was connected to Wright, government records show. Interviews with sources close to EITC Holdings Ltd, which has two of Wright's associates as directors, confirmed it was still working on filing patent applications and Britain's Intellectual Property Office has published another 11 patent applications filed by the company in the past week. The granting of even some of the patents would be significant for banking and other industries that are trying to exploit bitcoin technologies, as well as dozens of start-ups scurrying to build business models based around it. Patents that Wright has applied for range from a mechanism for paying securely for online content to an operating system for running an "internet of things" on blockchain. A patent schedule, one of a number of documents relating to the applications shown to Reuters by a person close to the EITC Holdings, outlines plans to apply for about 400 in total.

Submission + - Detritus from cancer cells may infect healthy cells (nature.com)

bmahersciwriter writes: Tiny bubbles of cell membrane — called exosomes — are shed by most cells. Long thought to be mere trash, researchers had recently noticed that they often contain short, regulatory RNA molecules, suggesting that exosomes may be one way that cells communicate with one another. Now, it appears that RNA in the exosomes shed by tumor cells can get into healthy cells and 'transform' them, putting them on the path to becoming cancerous themselves.

Submission + - File compression format Seminar reports/paper presentations/ ppt- free download (itpathshala.com)

An anonymous reader writes: The original Lempel Ziv approach to data compression was first published in in 1977, followed by an alternate approach in 1978. Terry Welch's refinements to the 1978 algorithm were published in 1984. The algorithm is surprisingly simple. In a nutshell, LZW compression replaces strings of characters with single codes. It does not do any analysis of the incoming text. Instead, it just adds every new string of characters it sees to a table of strings. Compression occurs when a single code is output instead of a string of characters.
The code that the LZW algorithm outputs can be of any arbitrary length, but it must have more bits in it than a single character. The first 256 codes (when using eight bit characters) are by default assigned to the standard character set. The remaining codes are assigned to strings as the algorithm proceeds. The sample program runs as shown with 12 bit codes. This means codes 0-255 refer to individual bytes, while codes 256-4095 refer to substrings.
The LZW compression algorithm in its simplest form is shown in Figure 1. A quick examination of the algorithm shows that LZW is always trying to output codes for strings that are already known. And each time a new code is output, a new string is added to the string table.

You should probably try to understand the context, or at least the definitions, before you go tossing around phrases like "one of the most profoundly stupid statements ever uttered by an economist."

You can study human behavior in a lab, at least on a statistical basis and within carefully designated boundaries. Outside those boundaries verification and falsification become rather difficult. For example, your experiments tend to become invalidated if the subject knows that they're being studied, and what the hypothesis is, since humans are adaptive and this knowledge may change their behavior. Also, human behavior is influenced by hidden variables which cannot be directly measured, in a lab setting or otherwise. What is studied in a lab are our purely physical limitations, and our psychological inclinations—neither of which is properly described as part of the study of human action per se. The former determines the scope of our actions, and the latter determines our preferences. The study of human action, however, is the study of how we go about satisfying those preferences; in other words, the study of choices. It is thus a general predictive model of human decision-making which Mises is placing outside the scope of verification and falsification by laboratory experiment, and rightly so.

If you start from the position that choices can be practically reduced to nothing more than measurable impulses in the brain then you have no use for the study of human action. However, even for the purest materialist there remains the fact that we do not currently have the capacity to make that approach practical. Just as chemistry remains a useful and independent avenue of study apart from physics, despite the fact that chemistry is in essence nothing more than the statistical study of certain classes of interaction between fundamental particles governed entirely by physical laws—because we currently lack the capacity and/or knowledge to make the leap from those fundamental particles to the overall properties of specific molecules and the reactions between them—so does praxeology (the study of human action) remain useful on its own merits, independent of the related scientific studies of physics, psychology, sociology, and the like.

I find this project very cool, are there any apps available that allow one to enter a speed limit as they see signs, and couple this with your GPS coordinates? I saw an android app here:


But I haven't rooted my G1 yet, so I can't install apps not on the market (which it isnt). If this isn't what that particular app does, it would be nice to write one.
