Google rolls out Google Play gift cards



Summary: Google has followed in the footsteps of Amazon and Apple, rolling out gift cards that can be used in its Google Play store.

Google has confirmed rumours that it is rolling out gift cards that customers can use to purchase apps, movies, music and ebooks from Google Play.
Last week, Android Police managed to reverse engineer an update issued by Google for the Google Play store, revealing code and resources that pointed to Google releasing gift cards. Earlier today, Google made the announcement on Google Play's Google+ page that it would, indeed, be stocking the cards at retailers. While they are not yet available in all stores, they will soon be sold from RadioShack, Target and GameStop, and only in the US.
Google declined to comment on the release timing for other countries, although ZDNetunderstands that the company is still interested in rolling out the cards to countries outside of the US.
The gift cards come in US$10, US$25 and US$50 denominations, have no fees, never expire and have a redemption code beneath a scratch-off panel. Users can enter the code on the Google Play website or on their mobile device. They can also enter the code online, by navigating toplay.google.com/redeem. Even if customers outside the US manage to obtain a card or its code, they will be unable to redeem it as Google will check their location and inform them that it is not available where they are.
The funds will go into the users' Google Play balance, which has a maximum limit of US$2000 and can only be topped up by using gift cards. Users are unable to split the cost of a single purchase between their Google Play balance and another form of payment, such as credit card.
The gift cards do have some additional restrictions. They can't be used for subscriptions or to purchase hardware, such as the Nexus 7, or any accessories, such as chargers or covers. Additionally, if a US user relocates or travels to a country that doesn't use US dollars in the Google Play store, they won't be able to use the card or Google Play balance.
The cards now offer parents a way to ensure that their teenagers can make purchases, without the need of a credit card. For users between 13 and 17 years of age, their Google Wallet account will only accept gift cards. Gift cards are not valid for users below the age of 13.

Why Windows 8 is terrible for desktops



Why Windows 8 is terrible for desktops
Microsoft released the final build of Windows 8, dubbed “RTM,” to developers and manufacturers last week. So how will it work on your desktop when it lands on Oct. 26?
Based on my tests, not very well. In fact, if you’re still using a desktop PC, you’re probably going to dislike Windows 8.
Microsoft has designed Windows 8 to work across almost all devices, with the exception of smartphones, a nearly one-size-fits-all approach to the operating system. That’s a marked contrast to Apple’s decision to use iOS for tablets and phones, and OS X on desktops.
On top of this, Windows 8 will share a kernel with Windows Phone 8 to make it easier for developers to create apps and games that work for both.
Unfortunately, Windows 8 doesn’t work equally well for all devices. How I work on a desktop is going to be different from how I work on a tablet. Using my fingers to navigate through Windows is a wholly different experience than using a mouse to click on things.
With Windows 8, Microsoft favors tablets, touchscreens, and laptops with modern touchpads. It works very well for these kinds of computers. Traditional desktops with a keyboard and mouse, on the other hand, have been left in the dust.

Desktop issues

True, a major part of the OS is devoted to the traditional Windows desktop. The desktop view is there if you need to run older Windows applications, or if you just want a familiar-looking interface.
But the desktop view isn’t what Microsoft is pushing. Much like Apple’s Mac App Store, there will be a Windows 8 Store available for downloading the new full-screen apps Microsoft is betting heavily on. (Notably, the store won’t offer older Windows programs at all.) These new Windows 8-style apps appear on your computer’s Start screen and run in a full-screen mode without menu bars or toolbars. Microsoft has referred to its Windows Phone and Windows 8 interfaces as “Metro”, but it has ditched the term and not yet given us a replacement, so I’ll refer to it as the “modern” design. Indeed, much of the focus for Windows 8 is on the sleek Start screen (image above).
Now let’s dig into some of desktop issues. (Let us know what other issues you see for the desktop in the comments.)
Dead mouse — Windows 8 isn’t meant for mice — it’s meant for fingers. The spread-out Start screen is more ideal for tapping than clicking, whereas the Start menu in Windows 7 is crammed into a tighter space to make it easier to click individual items. Scrolling using your mouse now moves the screen left and right instead of up and down. Mouse scrolling can be problematic inside some modern apps. Parts of the Bing Weather app, for example, are meant to be scrolled up and down and can interrupt you. (Check out this video for an illustration of this problem.) Basically, scrolling through apps with your fingers is much easier.
Right-clicking — When you right click your mouse in Windows 7, a menu pops up next to where you clicked to give you more options. Right clicking a picture, for example, brings up options like Preview, Cut, Copy, or Delete. Right-clicking a program on the desktop Taskbar gives you lots of helpful options too. But right-click menus go out the window in Windows 8, unless you’re using an old-style desktop app. Now, instead of a menu of options appearing right where you clicked, a limited number of options appear at the bottom of the screen. You now need to move your mouse to the bottom of the screen to select an option, and this gets incredibly tedious in modern apps and on the Start screen.
Small displays — The modern-style Start screen and modern apps look great on tablet screens and small displays, but they can get a little messy on a desktop PC with a large monitor. Modern apps aren’t optimized for larger resolutions, although Microsoft makes it possible to scale apps. Microsoft is preparing Windows 8 for the world where 10- to 13-inch monitors are the norm, as ZDNet points out. Thankfully, Windows 8 at least includesdecent multi-monitor support for power desktop users with two monitors.
Full-screen apps — Windows 8 already has some killer apps. Unfortunately, these apps are almost all better suited for tablets than desktops. There’s no “X” in the corner to exit apps in a single click like you can in Windows 7. Instead you have to click the very top of an app and drag it to the bottom of a screen to close it — an easy gesture on a touchscreen, but a laborious exercise with a mouse. It’s also not as easy to switch between these modern apps as it was with old-style desktop apps and the Windows 7 Taskbar.
Modern app switching — To switch between open modern apps using a mouse, you need to hover in the top left corner and then drag down to see the programs on the full left side of the screen. Only modern apps are shown in this lineup of open apps, not desktop apps. So if you want to switch between a modern app and an older desktop app, you need to go into the desktop and then select the desktop app you want. A two-step process has replaced the old one-step switch.
Screen splitting — Another issue with modern apps is the space allocated to them on the screen. When I work, I often divide my screen in two equal-sized windows. Modern apps don’t do this. You can only allocate roughly 25 percent of the screen to one app while the other 75 percent is taken up by another. This layout is not conducive to multitasking. Thankfully, you can still do a 50-50 split, or whatever tiling you’re used to, in the desktop area.
Hidden apps — It can be hard to find programs meant for the old-style Windows desktop if you don’t know where to go. From the desktop screen, you cannot launch desktop apps that aren’t already pinned to the Taskbar. That’s because the Start button is gone. Let’s say you use the Calculator app often. To access it, you have to go to the Start screen, right-click the screen, go to the bottom right-hand corner and select All Apps, then select Calculator. Once Calculator is open on the Desktop, you need to pin it to the Taskbar or you have to go through all of those steps again the next time you want it.
Internet Explorer tabs — This last point is minor, but the modern version of Internet Explorer 10 has no visible tabs. If you want to switch between tabs, you have to right click inside Internet Explorer to reveal your open tabs. I rely heavily on tabs to get my work done, so if you need them like I do, you’ll have to use old-style Internet Explorer from the desktop. While I don’t use Internet Explorer, it’s what comes available out of the box and many folks still use it. Alternately, you can download and use Google Chrome, whichincludes tabs in its modern app.

Tablet and touchscreen benefits

In its current form, Windows 8 is a tablet-centric OS. The interface works best on tablets, and we can’t wait to see it running on devices like the Microsoft Surface.
Windows 7 and Windows 8 are different beasts, and workflow is different when you have to deal with the Start screen versus the Start button. In Windows 7, I can do everything I can think of from a single screen. I can launch apps from the Taskbar or the Start button, I can easily re-size all my apps in different windows as needed, and everything feels optimized for an external mouse and keyboard.
Windows 8 requires me to switch between the desktop and the Start screen, which feels unnecessary. It shouldn’t take me extra steps if I choose to use a mouse, and that leads me to believe that Microsoft wants us to use tablets or ultrabooks instead of desktops. It also wants us to use full-screen modern apps instead of windowed desktop apps. (One exception: Microsoft Office 2013, which you launch from the Desktop but is more touch-friendly than past versions.)
The problems listed above show Microsoft is willing to alienate desktop users in favor of an interface that embraces touch screens and trackpads. Many businesses still rely on desktops for their workers, and it’s plausible that Windows 7 will remain the top choice for those businesses. That said, companies could adopt Windows 8 for tablets and hybrid laptops they want to deploy to workers.
After spending much time with Windows 8, I can’t recommend it for advanced desktop users unless Microsoft makes interface tweaks to make it more desktop-friendly. I don’t plan to upgrade my desktop from Windows 7 to 8 at launch because Windows 7 works so well. After several years of usage, I consider Windows 7 the best desktop OS ever, and I prefer it to Apple’s also-great Mountain Lion OS.
I expect Windows 7, with its 630 million licenses sold, will remain an incredibly popular OS for the next 10 years — just like Windows XP.

Microsoft Opens Windows 8 Upgrade Registration


Hands On With Windows 8 RTM
Microsoft today started accepting registrations for Windows 8 upgrades. Those who purchased a PC anytime after June 2 can now sign up to receive the Windows 8 upgrade for $14.99 when the OS is released on Oct. 26.
Back in May, Microsoft announced that anyone who purchased a Windows 7 PC between June 12, 2012 and Jan. 31, 2013 could upgrade to Windows 8 Pro for $14.99. Registration for that offer is now live viawindowsupgradeoffer.com for PC users in 140 countries.
After selecting your country, Microsoft will ask you to register your personal details and information about your new PC, including date of purchase, retailer, and PC brand and model. You'll also need your 25-digit Windows 7 product key.
On Oct. 26, Microsoft will start sending out promo codes via email. When you upgrade via Windows.com, Microsoft will display the $39.99 price for general upgrades; enter the promo code on the confirmation page to get the $14.99 price.
Users have until Feb. 28, 2013 to use their promo code.
Those who bought a PC before June 2 or have an older Windows 7 PC they'd like to upgradecan get Windows 8 Pro for $39.99 via Windows.com starting Oct. 26.
The Verge, meanwhile, reported that standalone copies of Windows 8 will cost $69.99 at launch, a price that will jump to $199 after Jan. 31, 2013.
In recent weeks, Microsoft announced that it will no longer be using the term "Metro" to describe the mobile-like interface within its new OS. Redmond said "Metro" was a codename all along, but there were reports that Microsoft stopped using the name because of a trademark challenge from Germany's Metro AG.

Bloggers show how to upgrade Windows 8 previews to RTM


Computerworld - Users of Windows 8 Release Preview can do a full upgrade to the final code, something Microsoft said was impossible, an IT consultant said today.
Microsoft has been clear that the Windows 8 previews were a dead end.
"There is no upgrade path from Windows 8 Consumer Preview or Windows 8 Release Preview to the Released-to-Manufacturing (RTM) version of Windows 8," Microsoft said in an FAQ posted on the company's TechNet support site. "If you have already installed Windows 8 Consumer Preview or Windows 8 Release Preview, you will be required to perform a clean install. The installation process will automatically create a 'Windows.old' folder that contains all files from your Windows 8 Consumer Preview or Windows 8 Release Preview installation."
A "clean" upgrade is the least effective migration, since it does not retain applications, user accounts and settings, and moves data files -- Word documents and Excel spreadsheets, for example -- to a special folder.
A Windows 7-to-Windows 8 upgrade, on the other hand, preserves virtually everything, from programs and user accounts to Windows' settings and files stored in default locations.
Denny Cherry, a senior database administrator, independent IT consultant and as "Mrdenny," a blogger for the IT Knowledge Exchange, recently posted instructions on how to fool Windows 8 RTM into upgrading the sneak peaks Microsoft offered users earlier this year.
The workaround -- which relies on editing the "cversion.ini" file in a downloaded copy of Windows 8 RTM -- tricks the installer into accepting upgrades from February's Windows 8 Customer Preview and May's Release Preview.
"Cversion.ini tells the installer the minimum build it can overwrite," said Cherry in an interview Tuesday. "By changing the version number there, it's allowed to overwrite the previews."
The cversion.ini file is only used to block previews of the final operating system; changing it does not affect the ability of Windows 8 RTM to upgrade Windows XP, Vista or Windows 7.
Cherry wasn't the only one who remembered that the same trick had worked three years ago when users wanted to upgrade from Windows 7 Release Candidate to the 2009 OS's final code.
Jason Fay gave the same advice as Cherry on his blog, and said he was able to upgrade Windows 8 Release Preview to the RTM bits without problems.
But he did have one caveat. "Keep in mind that this is not supported, and could end up with a catastrophic failure if some bits are not properly upgraded," said Fay. "But 12 hours in, and things seem stable."
Cherry said his upgrades were identical to those promised by Microsoft for Windows 7 users. "It's a traditional upgrade [that retains] all the settings and applications," he said. The only glitch he encountered was with Cisco's VPN Client, which required reinstallation on Windows 8 RTM.
cversion.ini
Changing the numbers in one file of the Windows 8 RTM installer lets users upgrade from Windows 8's free previews.
Although Cherry did not test the upgrade trick with a copy of theWindows 8 Enterprise 90-day trial, he expected that would work just as smoothly as to a perpetual license of Windows 8, like those Microsoft released last week to TechNet and MSDN subscribers, and to enterprises with Software Assurance plans in place.
Because the Windows 8 previews will expire on Jan. 15, 2013, users who want the longest free ride can wait out the next five months with Release Preview, then -- assuming the free eval is still available -- upgrade to the trial next January for three more months of use.

T-Mobile will offer unlimited nationwide 4G data plans starting September 5


Few smartphone users out there are happy with the way most carriers place limits on data plans. Many data plans out there offer you a specific allotment of data each month and if you go over that allotment, you either get charged more or your speed is throttled back. T-Mobile has made an announcement that mobile data users will really love; unlimited 4G data is coming.
T-Mobile has announced what it calls a truly unlimited nationwide 4G data plan. The plan will launch on September 5 and offers no data caps, no speed limits, and no unexpectedly high bills. The official name of the plan is the Unlimited Nationwide 4G Data plan. T-Mobile says it’s the only carrier in the US to offer completely unlimited 4G data access.
T-Mobile customers on the company’s Classic or Value plans will be able to upgrade their existing service to the Unlimited Nationwide 4G Data plan. You might be expecting the unlimited 4G plan to cost a lot of money, but it’s surprisingly inexpensive. When added to a Value voice and text plan the unlimited 4G data will cost $20 monthly.
When added to a Classic voice and text plan, unlimited 4G data will cost an extra $30 per month. At that rate, a T-Mobile Classic plan with unlimited talk, unlimited text, and unlimited 4G data would cost $89.99 per month. I suspect this plan is T-Mobile’s way of gearing up for the next-generation iPhone expected to launch next month. The next iPhone has been rumored to support 4G data.

Daunting task for jury in Apple v Samsung patent trial



After closing arguments, jurors face 109 pages of instructions and 20-page form for verdict

The nine-strong jury in the high-profile patent trial between Apple andSamsung faces the daunting task of ploughing through 109 pages of instructions on how to determine their verdict and a 20-page form in which to give it.
Closing arguments were made on Tuesday in the trial, in which Apple is claiming $2.5bn (£1.6bn) damages from South Korea's Samsung, which it says has copied essential cosmetic elements – the "trade dress" – as well as some of the functionality of its iPhone and iPad.
Samsung has hit back by alleging that Apple did not license key wireless technologies to which it owns the patents.
The stakes in the trial, being played out in San Jose, California, just 10 miles from Apple's Cupertino headquarters, are colossal. For Apple, winning the case would vindicate its aggressive stance towards Samsung in particular and the makers of smartphones running Google's Android software in general – a track down which its deceased chief executive Steve Jobs took it in 2010 after threatening to go "thermonuclear" over what he saw as copying by Google.
But if Apple loses, it would weaken its position substantially – and leave it open to a fresh attack from Google, whose Motorola Mobility subsidiary last Friday filed an aggressive lawsuit targeting nearly every Apple product, including the iPhone, iPad and its Macintosh computers, alleging that they infringe various functional patents.
The Apple-Samsung case has so far lasted for four weeks, and the jurors are expected to deliberate for another week as they try to untangle the complex forms – in which they have to decide, among other things, whether any of 21 different Samsung tablets and smartphones infringed any of 10 different patents on functionality – such as the "rubber band" effect when trying to scroll past the top of a list – and whether the "trade dress" of Apple's products is sufficiently "famous" to merit protection.
Apple has presented internal Samsung documents suggesting the company compared its own smartphones minutely against the iPhone in trying to design their own.
Samsung, for its part, has wheeled out products and designs which it says show that the iPhone's functions, such as tapping to zoom a web page, should not have been patented because similar features already existed.
Closing arguments from lawyers for the two sides finished on Tuesday, leaving the jury to consider their verdict. Legal sentiment has suggested that Apple has the home advantage – and that juries faced with the complexities of such patents vote for the side, or brand, that they most trust. That too could be an acid test for the two sides – although whoever loses is likely to appeal to a higher court.

Microsoft Puts out Call for Xbox Live Beta Testers


Xbox Logo
Microsoft today put out the call for volunteers to test out the next version of Xbox Live.
Those who are accepted will get the update via a software update to the Xbox 360 in the next few days, Larry Hryb, director of programming for the Xbox Live, wrote in a blog post.
The beta will feature a number of new features, including Internet Explorer for Xbox, recommendations and ratings, pinning and favorites, enhanced category search and discovery features, and voice search in specified markets.
Microsoft last invited users to test out an Xbox Live beta in July. "The amount of interest ... was so staggering that today we're announcing a second open call for Xbox Live subscribers to test out the beta program," Hryb wrote.
Microsoft is accepting "far more" beta testers this time around than it did in July, but Hryb still warned users to sign up quickly because the spots will fill up.
Users can register via live.com. Hryb told those encountering problems with the link to try again since high demand was hosing the system.
Those who are accepted into the 2012 Xbox Live Update beta will be required to sign a non-disclosure agreement, which presumably means you can't blab about what you see.
"Any participant who violates the NDA will be removed from this beta and all Xbox betas moving forward, and will not have access to Xbox Live until the end of this beta program period," Hryb wrote. "Our NDA enforcement squad is really good at finding violators; so save us both the trouble and don't test them. We also ask that you fill out a brief 5-minute survey at the end of the beta to let us know what you think."
A March Xbox Live update added a plethora of new content, including on-demand entertainment apps from HBO GO, Comcast Xfinity, and MLB.TV. The service also received a larger overhaul back in December.

Hamilton sets Minors stolen-base record


Billy Hamilton's third stolen base on Tuesday gave him 146 for the season. (Getty Images)
With his 146th stolen base of the season on Tuesday night, Reds prospect Billy Hamilton passed former Major Leaguer Vince Coleman's pro baseball single-season record, which was set in 1983.
Hamilton, 21, is Cincinnati's No. 1 prospect, according to MLB.com and has spent the season with Class A Bakersfield and Double-A Pensacola. Hamilton had nearly as many stolen bases (146) as hits (150) as of the fourth inning of the first game of Pensacola's doubleheader Tuesday against Montgomery.
In Game 1, Hamilton stole three bases after reaching in his first two at-bats. He walked in the bottom of the first and stole second base, then singled in the bottom of the third and stole second and third.
Coleman set the record while with Class A Macon in 1983. He went on to steal more than 100 bases in each of his first three seasons with the Cardinals and recorded 752 stolen bases in a 13-year career, placing him sixth on baseball's all-time list.
The team presented Hamilton with the base to commemorate breaking Coleman's record.
Hamilton, a second-round pick in the 2009 First-Year Player Draft, has not played in the big leagues. He began Tuesday having been caught stealing 33 times this season, good for a 82 percent stolen base success rate.

Binge Eating Among Men Steps Out of the Shadows




<strong>FIRSTHAND</strong> Andrew Walen, a recovering binge eater, now counsels others.”/><span class=Matt Roth for The New York TimesFIRSTHAND Andrew Walen, a recovering binge eater, now counsels others.
After downing 70 chicken wings in about an hour, Andrew Walen realized he had a problem.
Oh, he had known something was wrong over the years. Normal people don’t consume 4,500 calories worth of food in one sitting, or order takeout for four when dining alone. But it took a maniacal feeding frenzy for him to finally accept the reality: He was a binge eater, and he had absolutely no control around food.
“Ultimately, it was about numbing out and self-loathing,” said Mr. Walen, now 39 and a therapist in Columbia, Md. “There was this voice in my head that said, ‘You’re no good, worthless,’ and I turned to food.”
Mr. Walen is one of an estimated eight million men and women in the United States who struggle with binge eating, defined as consuming large amounts of food within a two-hour period at least twice a week without purging, accompanied by a sense of being out of control.
While about 10 percent of patients with anorexia and bulimia are men, binge eating is a problem shared almost equally by both sexes. A study published online in October and then in the March issue of The International Journal of Eating Disorders found that among 46,351 men and women ages 18 to 65, about 11 percent of women and 7.5 percent of men acknowledged some degree of binge eating.
“Binge eating among men is associated with significant levels of emotional distress, obesity, depression and work productivity impairment,” said Richard Bedrosian, a study author and director of behavioral health and solution development at Wellness and Prevention Inc., which works with employers and health plans.
But while binge eating is challenging for women who suffer from it, the perils are perhaps greater for men, who rarely seek treatment for what many believe is a “women’s disease.” Unlike bulimia and anorexia, binge eating does not even have a distinct listing in the current D.S.M., as the diagnostic guide for mental health professionals is known.
“Guys generally don’t come forward for any reason,” said Ron Saxen, 49, author of “The Good Eater,” a memoir of his struggle with binge eating, which began when he was about 11. At his worst, Mr. Saxen was consuming 10,000 to 15,000 calories’ worth of Big Macs, French fries, chocolate milkshakes, candy bars, ice cream and M & Ms, often within an hour-and-a-half window.
Those men who do seek treatment often have difficulty finding a facility or therapist to work with them — even the literature is predominantly female-centric. Before Vic Avon was given a diagnosis of anorexia in 2006, for example, he scoured the Web for information relating to men and eating disorders. “Everything I saw was written for and by women,” said Mr. Avon, 29, a building contractor in Brick Township, N.J.
Mr. Avon seesawed between anorexia and binge eating (not uncommon), at one point weighing 300 pounds. “I was so ashamed because it was a girl’s illness, I thought. I didn’t have any guys to look to.”
Many binge-eating men do not even recognize that anything is wrong. About 70 percent of people with binge eating disorder are overweight or obese, but a higher weight is generally more culturally acceptable for men than for women.
“There’s nothing wrong with a college guy eating a whole pizza by himself, but with women they would be horrified,” said Roberto Olivardia, a clinical psychologist who specializes in the treatment of body image disorders and eating disorders in men and is an author of “The Adonis Complex.”
Even if they are disturbed by their food intake, few men make the connection between gorging and emotional distress. “With men it’s usually a disconnect,” said Mr. Walen, the former binge eater turned therapist. “It’s about ‘I want to eat,’ not ‘I’m coping with an emotional trauma.’ ”
Adam Lamparello’s binge eating was both physical and psychological, the result of the starvation that ensued during his six-year bout with anorexia, and his attempt to fill the “emptiness, loneliness and emotional void” that he felt in his life.
“Those with binge eating disorder often do not have meaningful relationships with other people, are isolated, believe that life has no purpose or have suffered prior traumatic events and turn to food for emotional comfort,” said Mr. Lamparello, 36, a lawyer in Hasbrouck Heights, N.J., who recently published “Ten-Mile Morning: My Journey Through Anorexia Nervosa.”

Pardon Me! A Fearless Look at Our Bodies’ Mundane Functions



Getty Images

When you go straight to the most shocking piece of information in a book, there’s always a spoiler risk. So let me just say that the strange tale I am about to recount is one of many in this new book.

As you may have guessed, I am about to dip into the category listed in the subtitle as “beyond” yawning, laughing and hiccupping. It includes, among other behaviors, itching, crying, and the body’s two ways of expelling digestive gases, belching, and the other one.
The author, Robert R. Provine, would not be so reticent in describing the other one. In fact, Dr. Provine, a professor at the University of Maryland, Baltimore County, who has studied the behavior and physiology of laughing, yawning, tickling and other actions, denounces the priggishness that turns our attention away from intestinal gas, its origin and expulsion.
One of the results of this willful ignorance, which Dr. Provine points out in his book, is a shocking lack of verisimilitude in movies that feature the lighting of passed gas as a male ritual. In a sentence I never expected to read anywhere (an achievement in itself), he writes:
“The resulting methane jet produces a lovely blue flame, quite unlike the orange flame portrayed in Jim Carrey’s film ‘Dumb and Dumber,’ the flatus-fueled conflagration in ‘Dennis the Menace,’ and more recently that seen in Eddie Murphy’s ‘Nutty Professor II: The Klumps.’ ”
But as Dr. Provine pointed out in an interview, he may use humor, but that doesn’t mean he’s not serious about his subjects or that the subjects themselves are trivial. As he writes in the book:
“A gassy gut can be fatal, as it was for a patient having a colonic polyp cauterized. An electric spark caused the patient’s bowels to detonate, blasting out the colonoscope and ripping a six-inch hole in the patient’s large intestine.”
Hard to believe, right? So I pursued the footnote. Here, from the original paper in Gastroenterology in 1979 is part of the case report: “There was an explosion which was audible in the endoscopy room, the patient jerked upwards off the endoscopy table, and the colonoscope was completely ejected.”
Intrigued now, I followed the subject a bit further. Such explosions are rare, but they do happen. A 2007 review of the problem in The World Journal of Gastroenterology cited 20 colonic explosions reported in the medical literature from 1952 to 2006.
These rare explosions may offer insights into the best methods for colon cleansing. In the 1979 case report, mannitol, a substance that can be used in the procedure, was suspected as a potential cause because it was thought that bacteria might have metabolized it to produce methane. New preparations have been developed to avoid the problem.
I digress, to be sure, but I blame Dr. Provine’s book. With its many facts and anecdotes and unexpected stories, it begs you to continue where curiosity leads you, down both the boulevards and the back alleys of science. And that is exactly how he thinks science should be pursued. “You follow the trail wherever it goes,” he said, an approach that fits the “sidewalk neuroscience” he celebrates. Among the disparate findings he offers, from his own research and that of others: You can’t complete a yawn with your eyes closed. Someantidepressants produce yawns that trigger orgasms. Sniffing women’s tears can depress men’s sexual arousal. Fetuses hiccup early and often.
Among his suggestions for future work is more research on contagious yawning and mirror neurons, which are involved in our sense of self and in connecting to others. One aspect of small science that can be done without big grants is that it allows you to be fearless, which Dr. Provine certainly is. He notes, for instance, that both passing gas and speaking involve the expulsion of gas and vibration to produce a sound.
Why, he asks, did we evolve to speak with one end of our digestive pathway, and not the other? He’s not kidding.
I gave away the exploding colon story, so I won’t go into all the details about what sort of technical apparatus is needed for speech.
It’s all there in the book. And, says Dr. Provine, it may seem funny, but it’s no joke.
“I’m totally serious about the lessons for the evolution of speech,” he said, speaking with his mouth
