Nicotine is not addictive.

Or to put it more accurately: nicotine is not the addicting substance in cigarettes / tobacco. The careful analysis of lab tests (mostly done on rats and monkeys) shows repeatedly that nicotine fails to induce the effects we understand as demonstrating addiction.

However, the belief that nicotine is the substance that you crave when trying to stop smoking, is extremely lucrative to the nicotine-gum and nicotine-patch industry. In my country (France) the state's healthcare plan covers most of those products, making this coverage a (costly) disguised subsidy.

Submission + - Chemotherapy Can Make Cancer Growth Worse (gizmocrazed.com) 1

Diggester writes: The common treatment for cancer this day and age is chemotherapy but it is a very aggressive remedy that is not always guaranteed to work, and some new studies show it may actually be hurting more than helping.
The new study show chemo causing healthy cells to make a protein called WNT16B, which essentially fuels the cancer cells to keep growing and resist future treatment. This is absolutely the opposite effect wanted by patients and doctors, but this new research doesn't mean chemo should be canceled altogether.

Submission + - Bitcoin-Based Drug Market Silk Road Thriving With $22 Million In Annual Sales (forbes.com)

Sparrowvsrevolution writes: Every day or so of the last six months, Carnegie Mellon computer security professor Nicolas Christin has crawled and scraped Silk Road, the Tor- and Bitcoin-based underground online market for illegal drug sales.

Now Christin has released a paper on his findings, which show that the site's business is booming: its number of sellers, who offer everything from cocaine to ecstasy, has jumped from around 300 in February to more than 550. Its total sales now add up to around $1.9 million a month. And its operators generate more than $6,000 a day in commissions for themselves, compared with around $2,500 in February.

Most surprising, perhaps, is that buyers rate the sellers on the site as relatively trustworthy, despite the fact that no real identities are used. Close to 98% of ratings on the site are positive.

Submission + - How Apple and Amazon Security Flaws Led to Mat Honan's Epic Hacking (wired.com) 1

An anonymous reader writes: The story behind the hacking of Mat Honan's multiple accounts has been revealed and points to massive failures in how Amazon and Apple handle password recovery. Accounts for both sites can be easily accessed with simple to find publically available information. If you ask me, both companies should be liable for violating privacy laws.

Submission + - Amazon Kindle Book Sales Surpass Print In UK (techweekeurope.co.uk)

twoheadedboy writes: "Book lovers are increasingly turning to e-books, and in the UK Amazon has announced it now sells more e-books than physical copies on Amazon.co.uk. Kindle books surpassed sales of hardbacks in the UK back in May 2011 at a rate of two to one and now they have leapfrogged the combined totals of both hardbacks and paperbacks. The same happened in the US not so long ago, largely thanks to the popularity of novels like EL James' Fifty Shades of Grey, which started out as an e-book before being released in paperback."

Submission + - Federal Appeals Court Orders TSA to Explain Delay in Body Scan Public Hearing (wired.com) 1

rhsanborn writes: One year ago the District of Columbia Court of Appeals ordered the TSA to hold public comment on the use body scanners in EPIC vs. DHS. The order has been ignored prompting a WhiteHouse.gov petition asking for the Obama Administration's response. One year later, Wired reports, the court has ordered the TSA to explain why it hasn't responded to it's original order. The TSA has until August 30th to respond.

Submission + - Algorithmic Trading Glitch Costs Firm $440 Million (nytimes.com) 3

alstor writes: "Yesterday an update to Knight Capital Group's algorithmic trading software caused massive volume buys and sells, resulting in large price swings on the New York Stock Exchange (NYSE). As a result, the NYSE canceled some of the trades, but today the loss to Knight has been calculated at $440 million. Ignoring adjustments for inflation, this makes the cost of this glitch almost as much as the $475 million charge Intel took for the Pentium FDIV Bug, which might warrant adding this bug to the list of worst bugs. In light of this loss and the May 6, 2010 Flash Crash, perhaps investors will demand changes from firms using algorithmic trading, since the SEC is apparently too antiquated to do anything about it (PDF WARNING)."

Submission + - Traffic Jam in Space Threatens Satellites (scientificcomputing.com)

bigvibes writes: In April 2012, the European Space Authority lost contact with its Earth observation satellite Envisat, rendering it inoperative. Envisat will orbit Earth for approximately another 150 years before burning up upon re-entry into the atmosphere. If the enormous eight-ton ghost satellite were to collide with another object and break apart, the resulting debris cloud would escalate the already serious threat to operating satellites.

A new report by Allianz Global Corporate & Specialty (AGCS), titled Space Risks: A new generation of challenges, explores the considerable risks millions of orbiting fragments pose for satellites and space missions and stresses that the need to actively remove debris is now urgent. The report also highlights the insurance industry’s pivotal role in enabling the space industry.
