Way back in the day — say, a year or two ago — using search engines to research science topics was rather a crapshoot. I was an active Wikipedia writer back then, and the majority of my work was on science-related articles. And finding reliable web-based information was always challenging.

Take the article on the beautiful, endangered freshwater fish known as Asian arowanas, which is mostly my work (and I can't say I'm not proud of it). Google searches for Asian arowanas turn up mostly commercial sites and fan sites. Neither of these is a reliable source of science information: the commercial sites mix bona fide science with marketing information, while fan sites are prone to misinformation. This problem was a major hindrance to my work on the article.

Google search ranking

Now Google Search has a new feature for users signed in to their Google accounts: search ranking. (Try it.) Google says the ranking will help teach the search engine how to customize searches for you. Perhaps after some training, Google search will be less likely to turn up commercial sites and more likely to turn up useful research information.

But that will take time. In the meanwhile, two other search engines are available for people interested in finding real information on the web: hakia (still in beta) and Scirus.

Hakia, er, hakia

Hakia (whose name officially is not capitalized, but my inner English teacher just won't let me start a sentence that way) uses a new technology called semantic searching to help higher-quality, more credible sites show up higher in the search results, regardless of popularity. Other search engines, including Google, use popularity as a major criterion for search rankings; this is why SEO (search engine optimization) strategies include techniques like obtaining incoming links.

A script on the homepage allows a user to compare hakia and Google searches. I ran it for "Asian arowana." Hakia's top two sites were a fan site and a blog, while Google performed a bit better with the Wikipedia article and a commercial breeder's site. But a very significant difference between the two was visible on each page's right side: Google displayed an Adwords advertisement, while hakia showed a "hakia credible site": a journal article from the National Institutes of Health on the fish's mitochondrial genome. Hakia credible sites are those recommended by librarians, who know a thing or two about finding reliable information. Getting results like that "above the fold" is a huge advantage for the Web researcher.

Scirus

Scirus is billed as being "for scientific information only." It indexes journals, scientists' web sites, and other relatively reliable sources. In this regard, it is fundamentally different from both Google and hakia, which both cover the whole Web. So I compared it to Google Scholar, which searches academic journals.

My search for "Asian arowana" on Google Scholar turned up an unadorned list of various articles. The Scirus results, on the other hand, used logos to show each result's source at a glance. It also included a tool for refining the search. Scirus makes it easier to evaluate and filter search results. Its developers obviously understand the needs of a person looking for credible science information better than Google Scholar's designers do.

It's the weekend! I felt it was time to take a break from the weighty Right to Health Care series. What better way to relax than with online psychics?

At Online Psychic, you are invited to test your connection to a psychic. For FREE. Who could resist?

The link took me to a screen showing five face cards: K♥ J♣ Q♠ K♠ J♦ . Scrolling text (as if someone were... typing in real time!) informed me that a live connection was being established, then instructed me to pick a card and concentrate on it. The message warned that there may not be a strong psychic connection between us, in which case I should come back tomorrow.

I clicked "Continue," and Nancy's scrolling text told that me there was a strong psychic connection between us (oh goodie!) and that she had replaced the card I chose. And indeed, the card I chose had been replaced... as had been all four other cards: Q♣ K♦ Q♥ K♣ J♥ . And now I was invited to receive a more detailed reading about my life from Nancy for the low, low price of just $29.95.

Uh huh. Moving on...

At Free Psychic Network, I was presented with a box in which I was invited to type a question. I typed my question and clicked "Submit," and was carried to a page where I could submit my question (again) and have the answer e-mailed to me. I cleverly observed that this was a different site called Live Person, so apparently the question box was an ad. It's not an encouraging sign when your psychic subcontracts.

Nevertheless, I scrolled down and found a button for a Free Psychic Reading. No promises of a live psychic on the other end for me! My reading was:

Fortunate Encounter

I see a fortunate encounter with a stranger in your future.
The Crystal Ball Is Clear.
An nexpected chance meeting will provide a spring board for your carreer. (sic)

So my psychic is an optimist, but not a gifted typist.

Next I found Psychic Earth, which announces "Totally Free Psychics For Free Absolutely Free Psychic readings Online." A big golden button on the homepage advertises "Online readings only 1.20 (sic) per minute! Order here." The fine print at the bottom of the page (under the fold, of course) notes that "free readings are offered in the free reading room during scheduled times." The "free reading room" is a chatroom that was empty when I visited it.

So I ended up 0 for 3. I guess I need to find a better way to spend my weekend.
