Wearable Vicon Camera Lets You Log Every Moment of Your Life

Potentially taking the place of moms and their ever-flashing cameras, a new device allows people to document their lives simply by wearing it. According to New Scientist, U.K.-based firm Vicon has licensed technology from Microsoft Research Cambridge in order to produce the camera, which automatically snaps pictures as users wear it around their necks. The device, which can be programmed to take photos as often as every 30 seconds, whenever light changes in an environment, or when the camera detects body heat, was originally designed to aid the memory of Alzheimer's patients by allowing them to look back on their "lifelogs" at the end of each day.

Now, Vicon has plans to mass-produce the camera. It will retail for around $820 when it's released to researchers in the next few months, but will hopefully cost less when it hits store shelves in 2010. Dubbed the ViconRevue, the camera can store about 30,000 pictures on its 1-gigabyte memory card, and it's about the size of a pendant. For scientific purposes, we think this device is a great idea. But most folks, ourselves included, don't lead lives so interesting that they warrant dozens of photographs throughout the day. Making the sandwich and sitting on the couch is boring enough. Watching ourselves as we make a sandwich and sit on the couch would be intolerable. [From: New Scientist]

'Eyewitness' Testimony Can Be Influenced by Fake Video, Study Finds

If it appears on a video, or in a photograph, it must be true, right? A new study by a group of psychologists at the University of Warwick shows how dangerous it can be to accept video or photo evidence as fact, according to Wired.

In the study, 60 college students played a computerized gambling game, each student being matched against a researcher posing as a participant. If a player answered a question correctly, he or she could take fake money from a shared bank. Answer wrong, and he or she would have to put 'money' back into the bank. When the game was over, administrators showed each student participant a video that had been secretly altered to show the other participant (in fact, the researcher) cheating. Even though all of the students were told they should be 100-percent sure they saw the other cheat in person, and that confirmed cheaters would be punished, nearly half of the participants signed an eyewitness testimony based on the fake video. Some even "invented memories," according to researchers. When only told about the video evidence, a mere 10-percent gave an unwittingly false statement.

Cell Phone Ringtones Can Be Harmful to Memory, Study Finds



According to the Washington University in St. Louis (WUSTL), a new study in the Journal of Environmental Psychology claims that ringtones can have a damaging effect for memory retention, especially in the classroom. Apparently, distractions, such as ringtones, can have the most impact on the memory during times when the mind is absorbing new information (during a class, business meeting, or while studying, for example). The study, conducted in part by WUSTL postdoctoral psychology fellow Jill Shelton during her time at LSU, is titled: 'The distracting effects of a ringing cell phone: An investigation of the laboratory and the classroom setting.' No longer just an everyday nuisance, ringtones are apparently now memory blockers, too.

One of the experiments included having a cell phone ring loudly for 30 seconds in a classroom while a group of students listened to a lecture. Later tested on the material, that group of students scored 25-percent worse than another, non-distracted group that had listend to the same lecture. The case also observes that certain auditory distractions are worse than others. Shelton told WUSTL, "Depending on how familiar people are with these songs, it could lead to an even worse impairment in their cognitive performance." In other words, the more you know a song, the more distracted you will be.

Maybe it's just that a blaring polyphonic version of 'Single Ladies' reminds students of better times gone by. [From: Washington University, via Textually]

Scientists Make 'Progress' in Erasing Memories

Scientists Make Scientists just can't leave memories alone. Since first discovering the chemical PKMzeta in the brain, researchers have been playing with erasing the minds of rats in laboratories. By injecting mice with a drug called ZIP, scientists are able to block the activity of PKMzeta, which is believed to be essential for the retention and recollection of memories.

Original tests worked only on erasing the memory of tastes, but researchers at SUNY Downstate Medical Center in Brooklyn, the New York Times reports, have replicated the tests and, in so doing, successfully erased a broader set of memories. Scientists taught mice to navigate a small chamber by avoiding areas on the floor that would administer small electric shocks to their feet. The mice remembered the locations of the shock pads and avoided them, even a month later when placed back into the chamber. But, after having ZIP injected into their brains, the mice forgot how to correctly navigate the chamber, got shocked, and had to relearn.

Our Daily Deal: 4GB Laptop Memory for $28.99


The folks over at TechDealDigger are letting us know about some of the best deals they find on gadgets every day, so we're going to pass that information on to you. After all, in these tough economic times, every little bit counts. We may not be buying Swarovski-covered iPods any time soon, but everyone needs essentials like a computer, so take a look at what the online deals site sent us today.

Maybe you can't afford to cough up the cash for a brand new laptop, but you can greatly boost its performance with a cheap and simple memory upgrade. Memory is generally inexpensive, but we haven't seen any cheaper memory than this 4GB deal from Amazon. The catch? First, you'll have to send in for a rebate to get the price down to $28.99 (you'll pay $43.99 up front) and it's not exactly the latest or greatest tech: The 800Mhz DDR2 RAM from OCZ is a generation old, but that means that it will still work with most laptops (check with your manufacturer first). Regardless, you'll be hard pressed to notice the performance difference between this and the newer DDR3 -- unless you're doing a lot of gaming or video editing.

Save Your Memory With Your Cell Phone's Camera



These days we're somehow expected to keep passwords, phone numbers, bank accounts, PIN numbers, and countless other strings of numbers and letters in our memory, and it all needs to be ready for instant recall. Needless to say, we're always look for tips to make modern life easier, and geeksugar has gathered together seven memory-enhancing ways to take advantage of your cameraphone. Here are some of our favorites:
  • Parking lots at malls, airports, and stadiums continue to grow, so save yourself the trouble of trying to remember where your car is and take a picture of the row number.
  • Before traveling, take a picture of everything in your suitcase. It takes only a moment, and you'll be glad you've got the documentation in the event your luggage disappears during transit.
  • Drinking an excellent bottle of wine, but worried you won't remember it in the morning? Snap a shot of the label, and you'll be able to pick up another bottle the next time you're browsing the wine aisle.
  • Driving around in a city you've never been to? After parking, take a picture of the closest street signs, and you should be able to find your way back without a problem.
We'll admit we've been using the parking space trick for awhile now, and it's saved us countless times (especially in parking garages). A few words of warning though: You may not want to whip out your cameraphone in the airport security line, many museums don't allow picture-taking, and we've got a friend who was bounced from a strip club for surreptitiously snapping shots.

Check out the list for a few other tips, and let us know in the comments if you have any other inventive ways for using that tiny camera on your phone. [From: geeksugar]

Scientists Erase Memories in Mice

Scientists Erase Memories in MiceMovies have long had an obsession with erasing memories. 'Total Recall,' 'Eternal Sunshine of a Spotless Mind,' and 'Men in Black' all feature the intentional manipulation of memory as a central plot point. Until now, the concept of selectively erasing memories has dwelt in the realm of science fiction, but scientists believe they have made a major step towards making such a procedure a reality.

American and Chinese researchers have identified a protein, present in both mice and humans, called CaMKII that they refer to as the "memory molecule." CaMKII is key to the development and retention of information, and researchers have developed a method to turn its production on and off in mice.

Scientists exposed mice to potentially traumatic stimuli, such as light shocks to the paws. When the production of CaMKII was overproduced (during an attempt to force the mice to retrieve the memory of the stimuli), it appeared that the memory was not only blocked, but completely erased, without affecting other memories.

Of course, how exactly they can tell if it affected other memories isn't clear. They could simply mean that the mice still remembered how to walk and breathe, which isn't really terribly impressive. The research is interesting, but we'll keep our memories, even the painful ones, thank you very much. [From: Yahoo! News]

'Brain Games' Booming With Baby Boomers



What have you done today to keep your brain in shape?

Maybe it's time for you to get on board one of the latest trends in handheld and online applications: brain fitness. The market for brain training applications and products could reach $2 billion by 2015, according to SharpBrains, a market-research firm that tracks use of memory-improving and cognitive training programs.

While the trend toward hyperconnectivity with Google, GPS, and other tech conveniences may be dumbing us down, there is a large population searching for a way to keep their heads on straight. The market to improve the ol' trusty gray matter has seen major growth in the past few years as baby boomers are reaching their mid-to-late 60s -- it's more than doubled from $100 million in 2005 to $225 million only two years later in 2007. These folks want to stave off the forgetfulness and confusion they've seen their parents cope with as they grow old.

Games such as Sudoku and Nintendo's 'Brain Age' may be the most recognizable of these types of programs available, but there are whole programs on the market that claim to train people to think faster, remember more and expand the brain's capabilities. For example, Cogmed Working Memory Training is geared for people with attention deficit, and Lumosity is a popular online memory Web site.

Unlike older memory improving techniques, these newer brain training methods aim to make the process of thinking and memorizing more enjoyable -- it's about organizing information for improved recall, not cramming information into your skull.

Not every brain training solution necessarily involves gadgets and cutting-edge technology -- the card game of bridge has been touted for years as a way for seniors to keep their minds sharp. Break out the deck. [Source: CNN]

New Chip to Let iPods Hold 500,000 Songs


You're not going blind and that's not a typo.

In the current issue of Science, researchers at IBM unveiled a new type of media storage technology they say could give MP3 players the ability to store around 500,000 songs or 3,500 movies.

O M G.

It's called "racetrack" memory and it involves using the "spin" of an electron to store data. More explicitly, the researchers were able to "store data in columns of magnetic material arranged on the surface of a silicon wafer. The information moves around the columns at high speed, giving the technology its racetrack name."

The technology is similar to flash memory in that it has no moving parts and is unlikely to mechanically malfunction. Unlike flash memory however, it will not wear out after a few thousand uses. Oh yeah, and it's faster. A lot faster.

The biggest, baddest MP3 player on the market right now is the iPod Classic. It has 160-gigabytes (GB) of memory and holds up to 40,000 songs . We know what you're thinking. Weak Sauce. Don't throw away that old POS yet though, since devices boasting "racetrack" memory won't be in stores until around 2018. And yes, we know that's poop.

New High Speed, High Capacity Memory Cards On The Way

Let the memory wars begin anew. SanDisk and Panasonic unveiled some impressive advancements in memory cards at the kickoff of the Consumer Electronics Show in Las Vegas. Memory card maker SanDisk has attempted to make it easier for users with High Definition camcorders to choose the memory card for their needs by listing the actual recording time capabilities of each different size Video HD card. The largest, and thus most sought, is the 120 minute or 8 GB Video HD card that comes with the class 4 rating which translates into super-fast transfer speeds for those data intense HD recordings.

Panasonic decided to bypass the HD branding of its card and, instead, produced a world's first 32 GB SDHC (Secure Digital High Capacity) card. Also ideal for HD camcorders the card can be used with any other SDHC designated devices and features a class 6 label which puts its data transfer speed at the enviable 20MB/sec mark.

The SanDisk 8 GB Video HD card will be available this March at the MSRP of $139.99 whereas the Panasonic 32 GB SDHC card does not have a pricing or release date yet.

New Samsung Graphics Chip Will Be Fastest in the World



For gamers who live by the technological adage, "Better, Stronger, Faster" – well, your world just got a whole lot more exciting. Digitimes reports that Samsung has announced the development of the GDDR5, a new video memory chip that will be fastest graphics data processor of its kind in the world. This type of graphics memory chip is an integral part of a computer's video card, the component by which images and video from your favorite games are processed and transmitted to the screen.

The GDDR5, a series 5 double-data rate memory chip, transfers data at an astounding 6-gigabytes-per-second (GPps) and images at 24 GBps. Besides being about four times faster than today's widely used GDDR3, the new chip operates at 1.5 volts, which means that it uses about 20% less power than its slower contemporary. To put these numbers in perspective, the chip uses less power to be faster than your PlayStation 3 or Xbox 360. In other words, he GDDR5 promises to increase it and make your favorite state-of-the-art games more seamless and fluid. on big screens.

Samples have been sent to the top graphics processor firms, and mass production is expected to begin in 2008, with GDDR5 chips expected to be available sometime in the coming year. By 2010, Samsung claims the GDDR5 will capture about half the PC gaming market and be the standard for gaming memory chips. What does this mean for gamers? It suggests that the GDDR3 will soon be obsolete, and that the GDDR4, which has gotten positive reviews but has not been as ubiquitous as the GDDR3, won't be the top dog for long either. Customers who want the best, most fluid graphics will wait until the GDDR5 is available in video cards before making their next purchase. Sorry, gamers, but the bad news is that taking gaming to the next level will have to wait until next year sometime.

Scientists Erase Memories in Rats

Scientists Erase Memories in RatsIf you have a hard time remembering where you left your keys, you're certainly not alone. On the other hand, remembering things like the names of your parents or your favorite flavor of ice cream should be much easier. That's because long term memory, memories of things that you learned long ago, has generally been considered to be more or less permanent. However, researchers at Israel's Weizmann Institute of Science have recently managed to dispel that myth, making rats forget long-term memories.

In the experiment, rats were taught that a given substance tasted bad. They learned they didn't like it, and afterwards they avoided the substance completely. However, a month later (the equivalent of a year to humans) the rats were injected with a drug to block a specific protein inside the taste cortex. Once injected, they immediately forgot that the substance was undesirable to them and they tried it again.

The scientists' theory is that an enzyme in the brain known as PKMzeta works as so-called "memory machine," keeping long-term memories alive similarly to how a backup battery in your devices keeps things like internal clocks running even if the power is cut out. The drug they created blocks this process, resulting in memories being erased.

Whether this drug can be expanded to work on things other than tastes remains to be seen, but if all goes well it might not be long before you can take a pill that will make you forget all about that Flock of Seagulls hairstyle you were trying to pull off in the '80s. At the very least, this could make every visit to the ice cream parlor a refreshing and new experience.
