It turns out that surfing the Internet is actually good for you! A new study released by UCLA indicates that cognitive functions improve, even for seniors, after a little as a single week of surfing the Internet, giving credence to the old adage, “Use it or lose it.” Amanda Gardner writes on Health Day News:

“You can teach an old brain new technology tricks,” said Dr. Gary Small, a psychiatry professor at the Semel Institute for Neuroscience and Human Behavior at the University of California, Los Angeles, and the author of iBrain. With people who had little Internet experience, “we found that after just a week of practice, there was a much greater extent of activity particularly in the areas of the brain that make decisions, the thinking brain—which makes sense because, when you’re searching online, you’re making a lot of decisions,” he said. “It’s interactive.”

   —snip—

For the research, 24 neurologically normal adults, aged 55 to 78, were asked to surf the Internet while hooked up to an MRI machine. Before the study began, half the participants had used the Internet daily, and the other half had little experience with it.

After an initial MRI scan, the participants were instructed to do Internet searches for an hour on each of seven days in the next two weeks. They then returned to the clinic for more brain scans. “At baseline, those with prior Internet experience showed a much greater extent of brain activation,” Small said.

So forget all these studies that say the Internet is turning us all into attention-deficit info-snackers who skim rather than read. When you surf the Web, you’re not wasting time, you’re exercising your brain!

From photographer Alan Jaras (or Reciprocity on Flickr):

These are light refraction patterns or ‘caustics’ formed by a white light beam passing through shaped and textured transparent forms. The pattern is captured directly on to 35mm film by removing the camera lens and putting the transparent object(s) in its place. Colours are introduced by placing complex coloured optical filters directly in the light beam.

The processed film is digitally scanned for uploading. Please note these are not computer generated images but a true analogue of the way light is refracted by the objects I create.

Laurie Sullivan, reporting at Online Media Daily posts this amusing item about Google’s unintentional creation of what sounds to me like an Internet graffiti tool:

The Internet has a secret society. Anyone can join. It supports hidden messages. Those who want to belong need only download and install a special toolbar from Google that works in either Firefox or Microsoft Explorer (IE).

The toolbar, called Sidewiki, which launched in September, provides a venue for venting and posting derogatory comments on virtually any Web site that only those who install the toolbar can read. And although many realize that Google never intended that the toolbar be used for evil, some believe the Mountain View, Calif. company’s innovation could create a nightmare for marketers and Web site owners if they choose not to download and install the tool.

iCyte CEO Stephen Foley says it’s like painting on someone’s front door. The homeowner cannot do anything to prevent the damage, but uses their marketing dollars and time to clean up the mess. “Some might ask, well, can’t we just have transparency?” he says. “In this case, transparency has a deeper meaning. It means you have to declare your position. There are so many ways people can misuse this tool.”

Ya think? It seems preposterous that Google’s normally crack team of developers would not realize that they were unleashing a new gadget with the potential to turn the entire Internet into a widespread version of anonymous posting site 4chan, often referred to as the Internet’s collective id.

Examples abound of Sidewiki misuse. On the Go Israel website, someone using Google Sidewiki posted, “Yes, you too can join a country that has the highest abduction rate of female sex slaves in the world. Mossad doesn’t care so why should you! Regular Jews lived in peace with their Muslim friends until the Ashkenazi Zionist arrived.”

Just wait until the trolls at Free Republic get wind of this! Yikes!

Google gives participating sites the option to place their own “official” post on top of the public remarks, and offers a ranking system (i.e. voting) that pushes the cream to the top and theoretically allows the community to flag pornographic, disrespectful or potentially libelous posts. That’s the theory, at least…

Foley doesn’t believe that’s enough. He wrote a post in Google Sidewiki on Microsoft’s Web site titled “Has Google Started a War?” that discusses the ramifications of competitors taking swipes at each other’s Web sites, fundamentalists damning each other, and jilted lovers making their notes on the senior partners profile. “Oh, and do you think voting this down will help?” he writes. “We will just all head to the last Sidewiki to see where the dirt is. I am sorry Google but you are on a course of self destruct on this one.”

Today, Foley’s post ranks No. 24 with the highest positive score, but yesterday it ranked No. 1.

Foley’s post on Microsoft was just the beginning. Now he wants Google to change its policy and provide opt-in/opt-out features. It would allow owners to block anyone from posting comments on their Web site. So, he’s building a Web site set to launch at the end of the month. It will contain a petition asking the search engine to reorganize Sidewiki and make it an opt-in process.

Sounds like a plan, Google. A good one.

Trippy, must read science essay from the NY Times. As Keanu Reeves would say “Whoa…”

More than a year after an explosion of sparks, soot and frigid helium shut it down, the world?

 
Apparently every night throughout the world hundreds of people dream about this guy’s face:

In January 2006 in New York, the patient of a well-known psychiatrist draws the face of a man that has been repeatedly appearing in her dreams. In more than one occasion that man has given her advice on her private life. The woman swears she has never met the man in her life.

That portrait lies forgotten on the psychiatrist’s desk for a few days until one day another patient recognizes that face and says that the man has often visited him in his dreams. He also claims he has never seen that man in his waking life.

The psychiatrist decides to send the portrait to some of his colleagues that have patients with recurrent dreams. Within a few months, four patients recognize the man as a frequent presence in their own dreams. All the patients refer to him as THIS MAN.

From January 2006 until today, at least 2000 people have claimed they have seen this man in their dreams, in many cities all over the world: Los Angeles, Berlin, Sao Paulo, Tehran, Beijing, Rome, Barcelona, Stockholm, Paris, New Dehli, Moskow etc.

 
Update: Methinks this is a viral marketing campaign.

The horrors of marine mucilage:

As sea temperatures have risen in recent decades, enormous sheets of a mucus-like material have begun forming more often, oozing into new regions, and lasting longer, a new Mediterranean Sea study says (sea “mucus” blob pictures).

And the blobs may be more than just unpleasant.

Up to 124 miles (200 kilometers) long, the mucilages appear naturally, usually near Mediterranean coasts in summer. The season’s warm weather makes seawater more stable, which facilitates the bonding of the organic matter that makes up the blobs (Mediterranean map).

It gets worse:

But the new study found that Mediterranean mucilages harbor bacteria and viruses, including potentially deadly E. coli, Danovaro said. Those pathogens threaten human swimmers as well as fish and other sea creatures, according to the report, published September 16 in the journal PloS One.

Trailer for a new documentary film called DMT: The Spirit Molecule, based on the book of the same title by Dr. Rick Strassman MD. DMT or Dimethyltryptamine is one of the strongest hallucinogens known to man and each of us has a small amount of it floating around in our brains and blood stream. You can even make it yourself from a handful of a common type of lawn grass, distilled in a shot glass. The film features interviews with Dangerous Minds friends, author Douglas Rushkoff and visionary artist Alex Grey.
 

 
Smoking DMT, as the late Terence McKenna once said, is like getting shot out of a psychedelic canon. I agree. I’ve had some STRANGE experiences on the drug myself. It’s not for the timid, that’s for sure. DMT is not a drug you do for “fun” it’s a means of chemically connecting to an otherworldly “space” inhabited by strange and alien beings. Yes, you read that correctly. Think I’m joking? Smoke some, buster, then we’ll talk…

If you want a really good explanation of what the DMT experience is like, listen to this:

From New Scientist:

Crossing a microscope with a camera gives you a micrograph, a tiny photograph that allows artists and scientists to show the beauty inaccessible to the naked eye. Every year the Small World competition run by optics giant Nikon celebrates this hidden world. This year the winners range from an anglerfish ovary to the sex organs of plants via a rusted old coin.
