• More Near-Cures for HIV

  Early treatment may be key to a drug-free life for a small percentage of patients.

  Last week, scientists reported that a baby had been “functionally cured” of HIV (see “A Toddler May Have Been Cured of HIV Infection”). Now, other researchers report in PLoS Pathogens that 14 HIV-infected adults—four women and 10 men—have survived with the virus in check even though they have stopped taking their antiretroviral medications.  

  
  
  
  
  
  

• Which Google Reader Replacement Will You Use?

  Google kills its Reader, beloved by many (but not enough).

  Across the Internet, journalists and news junkies are letting out a sustained cry: “Why, Google, why?” The company announced late Wednesday that it would be killing off Google Reader, its RSS platform. I use Google Reader daily. So do yet more eminent journalists. But the Great Googlers have determined that Reader’s user base is too small for them to justify the upkeep, and who are we to blame them?’

  
  
  
  
  
  

• Twenty-Five Years in Prison for Helping Hackers? Seriously?

  A maximum sentence of 25 years for enabling hackers to vandalize a news website is totally nuts.

  Yesterday, the U.S. Department of Justice announced that it indicted Matthew Keys, 26, Reuter’s deputy social media editor, for allegedly enabling some members of hacker organization Anonymous to hack and change content on the LA Times’ website back in 2010. The possible maximum sentence he could face if convicted? Twenty-five years in prison.

  
  
  
  
  
  

• Will Methane Hydrates Fuel Another Gas Boom?

  Energy-hungry Japan extracts natural gas from deep-sea methane hydrates, but it’s not clear whether the “flammable ice” makes economic and environmental sense.

  In a move to get closer to developing its own domestic fossil fuel, Japan is extracting natural gas from an offshore deposit of methane hydrates. The tests that are set to run until the end of this month mark the first time such production methods have been tested in a deep-sea formation.

• Google Searches Beyond AdWords

  Personalized and interactive advertising experiences are becoming a lot more important than just simple banner ads.

  Would you follow your favorite basketball player’s shoes on Facebook or Twitter? That’s right: the player’s shoes, connected to the Web and posting status updates live from the basketball court. Bizarre as it sounds, this could happen in the not-so-distant future of digital advertising and marketing, if some of the ideas conceived by Google’s latest advertising experiment, Art Copy & Code, take flight.

These ambitions are now moving closer to reality, as more people begin to experiment with their setup, although significant challenges remain. 

  
  
  
  
  
  

• Smartphones Are Eating the World

  Smartphones have created a bridge between two previously separate industries—wireless networks and personal computing. For Internet firms and device makers, this means access to the world’s largest network of people. As can be seen above, the wireless telephone business is large compared to personal computing. In 2012, the world’s mobile operators did $1.2 trillion in business and served around 3.2 billion people, versus perhaps 1.7 billion people who used PCs to access the Internet. By comparison, the combined revenue of Microsoft, Google, Intel, Apple, and the entire global PC industry was $590 billion. Online advertising, the main driver of the consumer Internet, generated only $89 billion in revenue.

  
  
  
  
  
  

• Unintentional Interfaces: Google Reader's Censorship-Busting Power Will Be Hard to Replicate

  Google’s brand name made Reader work in Iranians’ favor.

  Journalists and other professional nerds are angry that Google is snuffing out its moribund RSS software, Reader. But as Quartz’s Zach Seward points out, plain old normal folks in Iran used Reader quite a bit to get around internet censorship. And those users won’t be helped by the Reader clones popping up in its wake, because Google Reader’s unintended power as an anti-censorship interface flows from its “Google” pedigree, not its “Reader” functionality. 

  
  
  
  
  
  

• MRI Scans Reveal Distinct Brain Injuries After Concussion

  Sorting concussion patients based on internal brain injury could help doctors identify those with more severe cases.

  Brain scans may be able to detect two distinct kinds of brain injury in patients who have suffered a mild head injury or concussion, say researchers from the National Institute of Neurological Disorders and Stroke. Differentiating between the two may help doctors better treat patients.

  
  
  
  
  
  

• The Meaning of the Google Glass Backlash

  Has a product ever provoked as much hostility before even hitting the market as Google’s geek specs are generating? There’s something special about the eyes.

  Almost 10 years ago I spent a day in Toronto with computer scientist Steve Mann to understand why he strapped a PC to his body and wore a camera and a monitor over one eye. He argued that it was the optimal method of using a computer, which meant that eventually everyone would want to do it. That prospect unnerved me, because being with Mann was difficult. He seemed distracted by whatever was over his eye—or at the very least, I worried that he was paying more attention to it than to me. Whether it was the best way to interact with a computer seemed like the wrong question; it was certainly a suboptimal way to interact with a fellow human being. It struck me as fundamentally rude to put something in front of your eye but not let the other person see it—the equivalent of whispering a secret in front of someone else.

  
  
  
  
  
  

• Reining in Geoengineering Researchers

  A Science article suggests a framework for monitoring research on how to cool the earth.

  Efforts to reduce carbon dioxide emissions worldwide aren’t working, so some researchers think we may need to resort to spraying reflective aerosols into the upper atmosphere to shade the earth and cool it off a little. The problem is we don’t know much about what that might do to the ozone layer or precipitation, among other things. And we don’t have laws to regulate geoengineering research to make sure someone doesn’t do something stupid, like doing a large scale test before we understand the impact of the aerosols, at least on a small scale, on atmospheric chemistry..

• Years in the Making, Promising Rechargeable Metal-Air Batteries Head to Market

  A Scottsdale, Arizona-based startup is now selling batteries that promise to be a cheaper alternative for grid backup.

  After years of development, a novel battery technology from the startup Fluidic Energy is being commercialized (see “Betting on a Metal-Air Battery Breakthrough”). It’s a rechargeable metal-air battery whose first application is replacing diesel and lead-acid battery backup systems for telecommunications towers, and for other businesses that need a steady supply of power. The company has been quietly demonstrating its battery with customers for a year. In an interview with MIT Technology Review, Fluidic Energy founder and chief technology officer Cody Friesen made details about its product publicly available for the first time.  

  
  
  
  
  
  

• I Want Frictionless Privacy

  Netflix now allows frictionless sharing of the movies you watch on Facebook.

  Back in 2011, following Facebook’s F8 developers conference, a new phrase began to buzz: “frictionless sharing.” Soon, news-sharing apps proliferated with Facebook, which enabled automatic posting of articles you were reading to your news feed. More famously, Spotify originally required users to register via their Facebook account. Spotify claimed that it was all just to make things simpler for the user: “As most of our users are already social and have already connected to Facebook, it seemed logical to integrate Spotify and Facebook logins,” the company said in a statement. But the move was transparently to create viral buzz in Facebook news feeds. Pretty soon, my feed was full of the unneeded “news” that Joe was listening to Kanye, while Kate was listening to Madonna. My listening habits were likewise broadcast, and though I think I’ve disabled them, I’m not entirely sure (last I checked, the Spotify iPhone app’s privacy settings remained a bit opaque to me).

• Cellulosic Ethanol Inches Forward

  The technology for making fuel from wood chips and grass is late, but still on the way.

  A few years ago, large scale, billion-gallon-a-year cellulosic ethanol production seemed around the corner. Instead we’ve seen companies fail, or scale back and delay their plans, as they find it hard to secure financing or bring down costs. The technology seems to have dropped off the radar, except for the occasional news of opposition to a mandate requiring the use of cellulosic ethanol.

The latest considers what it would take to run New York State with sources such as wind and solar. The resulting headlines look great, and a lot of people walk away with the general impression that, if we wanted to, we could easily drop fossil fuels and nuclear power.

  
  
  
  
  
  

• A Tale of Two Newspaper Interfaces

  The New York Times “prototypes” a new site design for readability, while The Daily Mail mints money by actively thwarting it.

  The New York Times revealed a “prototype” of a new online “article experience” yesterday. Was it a bold technical experiment, a new multimedia whatzit, a paradigm-busting business model? No. It was just an article, laid out… readably. That is, in such a way to encourage reading. Ian Adelman, director of digital design at the Times, told me in an email that this “prototype” is intended to “create an appealing and engaging environment for our readers/viewers, as well as for advertisers.” You’d think that the essential, obvious point of a newspaper website interface is to do exactly that, and that the essential, obvious way to accomplish it is to set said interface up in a way that encourages reading, which is the essential, obvious thing that someone comes to a newspaper website to do. This, apparently, is innovative and risky enough to require prototyping?

Writing, and reading, these posts can also lead to negative feelings like sadness.

  The small-on-purpose social network adds new features, but no clear purpose.

  The tech world was buzzing about Facebook’s redesign yesterday, but I was more interested in what was new at the “anti-Facebook,” Path. If you haven’t heard of it (and, given that it only has 6 million users, you may not have), Path is a mobile-only social network that limits you to 150 connections. The idea is that this limitation matches the limit most humans have on maintaining meaningful relationships. Path, then, is supposed to be the social network where your “real” friends are. On Wednesday Path released, um, “Path 3” (they like to issue product updates as if they’re movie sequels), which includes private messaging, “Stickers” (large emoji, basically), and a “Shop” (where you can buy the Stickers and photo filters).
