Recently a new search engine appeared on the WWW called Google, and a lot of expert searchers and amateur searchers alike are singing its praises. What makes Google so special? Several attributes, but principally its ability to filter for more desirable sites in its search results.
All search engines use some sort of algorithm against which they sort search results in an effort to let the more relevant “hits” float to the top of the list. Considerations of relevancy might include factors such as how often your search keywords appear on a webpage, whether they occur at the beginning of the webpage or toward the bottom, whether they are included in the title of the webpage or in the webpage metadata, etc.
The Google algorithm is based on a different concept – the concept of popularity. A webpage is deemed more important than another if a larger number of other webpages have linked to it. There are other search engines that also look at link popularity, but the algorithm used by Google is quite complex and takes into consideration the relative “importance” of the linking pages as well. If, for instance, your initial query is in the field of chemistry, the webpages that will “float to the top” of your hit list will be the ones that contain your search keywords, and that have been linked from the largest number of other chemistry websites – and additional cachet may be given to websites linked from other sites that are known to be particularly good websites in the same field (i.e., they themselves are highly linked-to from other pages). Think of it as a sort of peer review. The sites that fulfill your search parameters, and that have received the highest peer review rating, will be at the top of your results page.
Nothing is foolproof, of course. Consider the case of an excellent webpage that is brand new. Other webmasters have simply not had the opportunity to find it and to modify their webpages to link to it. It will probably turn up near the bottom of your hit list even though it may be clearly the best webpage going on your particular subject.
But, by and large, many searchers that I admire feel that Google often gives them better, cleaner search results than other search engines. Which means a considerable saving of time.
Google also presents a web directory (http://directory.google.com/), like Yahoo, but, again, the webpages in the directory are laid out in order of relative “importance” rather than in alphabetical order. This means that if you are, for instance, looking for a service, like an online auction page, the top webpages on the list will be the ones that more people continue to use most frequently, and one assumes that folks wouldn't be continuing to use the pages if they weren't working well for their needs. This I really like! Will it replace Yahoo? Not yet. Yahoo is still the biggest directory on the web, to my knowledge. But if you are looking for only quality websites, the Google directory is a very nice addition to the field.
Another interesting Google feature is that the search engine “caches” the webpages it indexes. This means that if a webpage has disappeared or changed its URL between the time Google indexed it and the time it pops up in your Google search, you can still get a “picture” of the website from Google by clicking on the “cached link”, which is right after the URL. Imagine! A way to get around those pesky 404 error messages … I find this to be mind boggling … Again, it isn't 100%. Not every page contained in Google is actually indexed by Google. And some sites apparently ask Google not to cache them. Still, what a great feature!
Is Google my favorite search engine? No, it is not. Alta Vista is still my favorite, because I really like the ability to run an extremely complex search statement, and other search engines do not give me the kind of control over my search that I find with the Alta Vista advanced search screen. And Hotbot gives a much more detailed structured search screen – lots of choices. But that is only my personal preference. Do I use Google? You bet I do! You should give it a try, too. Always remember that different search engines have different strengths and weaknesses, and they all look at different parts of the WWW in different ways. If you limit yourself to one search engine, you are missing more than you can even imagine. If you don't get good results with the first or second try of a search on a particular search engine, always switch to another. No sense beating a dead horse …

On Thursday March 23, 2000, a historic milestone was marked as researchers announced they have completed mapping the genome of the fruit fly, Drosophila melanogaster. The achievement, which was announced in a special issue of the journal Science, culminates close to 100 years of research. Drosophila melanogaster is the most complex animal thus far to have its genetic sequence deciphered. The findings have important implications for human medical research and for completing a map of the human genome. Mapping the fruit fly genome has been a broad collaborative effort between academia and industry in several countries. While a foundation was laid by US (Berkeley), European, and Canadian Drosophila Genome Projects, Celera Genomic finished the job over the last year by employing super-computers and state-of-the-art gene-sequencing machines. The techniques learned and used in this last phase of mapping may now be applied to more rapidly decode genes of other organisms, including humans. This week's In The News takes a closer look at this important landmark.
The Washington Post (1) offers comprehensive coverage of the findings in its March 24, 2000 article, “Mapping of Fruit Fly a Genetic 'Milestone.'” Discovery.com (2) follows up with additional news. Next, Celera Corporation, responsible for the final high-tech stage of completing the sequencing, provides this CeleraScience page (3). This page contains three related articles as well as links to other sections of the CeleraScience site, including a Discover System link with access to the Celera Drosophila Sequence. Fourth, the National Center for Biotechnology Information offers a Drosophila melanogaster Genome Page (4) with access to the actual genome sequence data. Flybase (5) is an outstanding resource and includes a database for information on the Drosophila Genome. The sixth resource, the homepage for the Berkeley Drosophila Genome Project (6), represents fundamental research for this project with BLAST, a search feature for the Drosophila genome; a Berkeley Fly Database; Map Viewers; Analysis Tools; and online publications and laboratory methods. Next, for those users interested in the National Institute of Health's Human Genome Project (7) for which this research has important implications, this page offers links and background. Finally, users with institutional access or personal subscriptions can access the original research as it appeared in a special genome research issue of Science Magazine on March 24. 2000 (8). This page offers a section referring back to Genome Landmarks and past special Science issues devoted to genomics. [KR] (From the Scout Report)
WW2010: The Weather World 2010 Project
University of Illinois has developed “a WWW framework for integrating current and archived weather data with multimedia instructional resources using new and innovative technologies.” Some pages need a fast Internet connection, and they still cling to Fahrenheit temperatures, but the content is rich and well formed.
U.S. National Oceanic and Atmospheric Administration must have the world's biggest weather-related Web site. Fortunately, much of it is written at a level that is suited to inquiring youth.
Meteorological Service of Canada
The Meteorological Service of Canada maintains a smaller website with a friendly approach. A parallel organization, the Canadian Meteorological Center at http://www.cmc.ec.gc.ca/, has the heavy stuff (scientific tables, satellite data, etc.)
Live Weather Images
If you have an Internet connection fast enough for downloads of graphic images, add this to your “weather supersites” list. It links to hundreds of satellite weather images, all over (literally) the globe – showing everything from snow depth to typhoons to tree pollen. My favourite is “N & S America Cloud Cover” (filed under “Current Weather Images in General”), the current GOES-8 radar image of nearly half the planet! As your students view it, ask them to determine with the help of a globe or world map:
It's a problem-solving exercise in circle geometry, using the usual theorems plus longitude. Younger students can answer it intuitively. WeatherImages is maintained by Mark Brooks of Albemarle, North Carolina, with the support of voluntary donations from its user base. Thanks to Norm Gilberstad of the B.C. Ministry of Education for suggesting this site.

National Drought Mitigation Center (NDMC)
The School of Natural Resource Sciences at the University of Nebraska-Lincoln hosts this site on drought mitigation. Designed to help “reduce society's vulnerability to drought,” NDMC offers a wide range of information on drought and how to prepare for and deal with it. Newcomers should start at the Drought Science and Impacts sections for background information. The Drought Watch and Climatology sections offer access to a huge variety of online data summaries, tables, and maps – including several indices of current drought condition in the US – in addition to links to related research sites. (NDMC is also one of the several agencies responsible for the Drought Monitor, discussed in the February 2, 2000 _Scout Report for Science and Engineering_). For information on mitigation, see the Mitigation, Drought Links, and Network sections. Given the large proportion of the country currently classified as being on drought watch or experiencing drought, this site will serve as a timely information resource for students, educators, or the general public.

The Day of the Black Blizzard
This is a subsection of the excellent Discovery Channel Online site and provides a glimpse into the lives of people living on the US Great Plains. The story is told of the day dust became a terror. Farmers in this region had always suffered the Dust Blues but what started as a gentle breeze on a hot summer's day became a tidal wave of dust 7,000 feet high by mid-afternoon which engulfed the area and dropped the temperature 50 degrees. The site provides audio clips of eyewitnesses, such as Harley Holladay who was a slip of a lad at the time of the Black Blizzard of Palm Sunday back in 1935. Hick, yey!

American Historical Images On File: The Native American Experience
“This collection of historical photographs is provided with the permission of Facts on File, Inc., and is a comprehensive collection of images of Native American people. The collection is arranged chronologically from the prehistoric period and the Paleo-Indians to 1990 and the appointment of R. Richard West as director of the National Museum of the American Indian. The collection includes information and images which describe the lifeways of various tribes and include historical entries for particular Indian groups. Narrative is provided that provides the historical and cultural background describing the event, person, or subject presented.” This is a true treasure trove. The images are fascinating and thought provoking. They include paintings, drawings, sketches, and photographs. The brief narratives (descriptions) of each image put them in enriching context.
Prelude to the Study of a Totem Pole
This Website, designed by a graduate student in anthropology and supported by the University of British Columbia's Museum of Anthropology, focuses on the history and meaning of a Thunderbird totem pole carved in the mid- to late-1800s by a member of the Gitanyow tribe from the upper Skeena river area in British Columbia. The innovative Website has three components. The In the Village section offers a history of the tribe, the carver, the commissioner (Chief Wixha), and the village in which it was erected. Betwixt and Between explores the time when “the Thunderbird totem pole was in storage or transit between its original home in the village of Gitanyow and its present home in the Museum of Anthropology.” Finally, In the Museum discusses the pole's cultural and spiritual significances as determined by scholars. The result is a site not only well-linked and highly informative about the totem poles and culture of this area, but one that examines the processes by which “native” meanings are inevitably recontextualized by institutional involvement. A CD-ROM based on this site is due out this year. [DC] (From the Scout Report)

A diverse perspective on memory from sheep brain dissection and memory artists to memories of Nagasaki. Chopping up the ovine brain for instance provides clues about the anatomy of memory, while those of an artistic bent will enjoy the attempts of one artist to paint his childhood hometown from memory and then to compare the views with photographic evidence. The significance of particular places comes through in the paintings, something that is not tangible in the photos demonstrating how memories shape our personal landscapes. There is plenty more, so don't forget to pay a visit. (From New Scientist Planet Science)

A FAST NEW NETWORK
The next-generation Internet2 is serving as a test environment for new applications that will eventually improve the performance of the traditional Internet. Already, more than 170 universities participating in the project are able to collaborate on the high- speed network in real-time and move huge volumes of data in less than a second. Although individuals will never be able to buy Internet2 connections, some of the advances made on Internet2 will be incorporated into the public network over the next five years, says Internet2 director of communications Greg Wood. The Next Generation Internet, which includes several dozen networking projects such as Internet2 that are now in progress, eventually lead to a faster, more intelligent, and more reliable Internet. The Internet2 project began in 1996 as a way for the research community to continue with its plans for the original Internet, which became slow and commercialized in the mid 1990s. Internet2 applications such as video technology and multicasting are already making their way into the mainstream, says Wood.

TEACHERS ONLINE BUT DISCONNECTED
Teachers across the nation say they often lack the time, formal training, and readily available help required to effectively integrate technology into the classroom and create the kind of interactive learning atmosphere many educators and business executives believe enhances the learning process. Contrary to popular sentiment, simply putting computers in every classroom is not enough to ensure the equipment will be used to supplement classroom instruction. Some teachers spend hours at home every night attempting to create computer-aided lessons, but most abandon or avoid the undertaking altogether because they lack the patience or know how to successfully attempt such projects.
Although some schools offer formal computer training and employ a technology specialist to
help teachers with efforts to build technology into their instructional methods, the training
is usually not extensive enough and the specialists must often be shared between multiple
schools. Several different groups have recommended ways for school districts to improve the
situation, including placing a full-time specialist in every school, building more planning
time into teachers' schedules, offering more comprehensive computer training classes, and
enacting more stringent standards for technology competency.

NET SPEED AIN'T SEEN NOTHIN' YET
Scientists at Lucent's Bell Labs have set a new record for transmitting data over fiber-optic cable by moving 3.28 terabits per second of data over 300 kilometers of Lucent's TrueWave optical fiber. At this rate, Lucent's fiber in one second could transmit three times the volume of daily Internet traffic for the whole world. Within years, fiber-optic cable could move tens of thousands of terabits per second of data. This tremendous bandwidth growth will be fueled by the speed of lasers used to encode data and the number of wavelengths a single fiber can carry at once, says AT&T Labs President David Nagel. Researchers are now developing terabit lasers, and the number of pulses a single laser produces is doubling every 18 months. In addition, the number of wavelengths a single fiber can carry at one time is doubling every year. Eighty-wavelength systems are already available, and scientists are working on 1,000-wavelength systems. The Bell Labs' record accounts for less than half a percent of the potential capacity of current optical networks, according to Kerry Vahala, professor of applied physics at the California Institute of Technology.

NEW DEVICE COULD BOOST DATA SPEED
A group of researchers on Thursday announced the development of opto-chips, a breakthrough technology that could greatly increase the ability of fiber-optic networks to provide high-bandwidth Internet access. The device is a sophisticated electro-optic modulator that sends data as light signals through fiber-optic networks at least 10 times faster than current electro-optic modulators. Meanwhile, the new technology needs only 0.8 volts to operate, compared with the 5 volts today's devices require. Another advantage of the new modulator is that it does not lose as much data as today's modulators, which can lose signals and disrupt data streams. Researchers made the new modulator from polymers, while traditional modulators are grown as crystals from lithium niobate. Opto-chips could allow fiber-optic networks to provide high-speed Internet access to an almost unlimited number of customers, and the technology could be commercially available in two years if it passes long-term testing. Eventually, opto-chips could enable users to download movies and huge music files instantaneously, although a number of other technologies would need to be developed first to make this possible.

NEURAL NETWORKS MAY TRANSFORM COLLEGE PLANNING
Johns Hopkins University is testing the use of an artificial neural network to determine which applicants are likely to enroll in the school. The neural network is a statistical model that imitates the ability of neurons in the human brain to learn patterns. By looking for patterns in student data, the neural network finds the common characteristics of applicants who enroll at Hopkins. Admissions officers could use the neural network to predict which students are likely to enroll and which are not, using the information to decide how many students to accept to ensure a full class. Richard Reeves, who invented Hopkins' neural network last spring using StatSoft's Statistica software, says 50 percent of universities will use neural networks in 10 years. Although colleges already use statistical models to predict how many students will enroll, tests at Hopkins showed that the traditional model had an error rate of 6 percent while the neural network had an error rate of 3 percent. The technology used in neural networks has been available for many years, but only recently have hardware and software become powerful enough and cheap enough to make neural networks viable for common use.

INTERNET GETS AN 'A' FOR SCHOOLWORK
Although parents express concerns about their children's Internet usage, 43 percent of children in the nine-to-17 age group say they have a more positive outlook about school due to using the Internet, according to a survey to be released today by the National School Boards Foundation and Children's Television Workshop. The survey of more than 1,700 parents and 600 children finds that 53 percent of parents and 48 percent of children who have home access to the Internet use the medium mostly for schoolwork. National School Boards Association Executive Director Anne Bryant says school leaders across the nation will examine the survey's findings to determine how the Internet can best be used to help educate children. The possibility that their children may see pornography on the Internet is a top concern to 46 percent of parents, while 29 percent are wary of adults who may contact their children online, and 29 percent are worried their children may come across violent content on the Web. A great majority of parents say the Internet has not significantly altered their children's lifestyle habits, such as the amount of time they spend reading or with friends and family.

RURAL AREAS MAY LAG BEHIND IN WEB REVOLUTION
The Senate commerce, science, and transportation subcommittee met yesterday to discuss ways to bring broadband Internet access to rural areas so all U.S. consumers can participate in the Internet revolution. Broadband providers mostly offer access to urban areas where demand is high enough to make the services profitable. At the hearing, Sen. Jay Rockefeller (D-W.Va.) and Sen. Olympia Snowe (R-Maine) introduced legislation that would provide a tax break to firms that invest in broadband networks in areas more than 10 miles from the closest town with 250,000 people or more. Rockefeller said, “Unfortunately, rural areas are at a significant technological disadvantage.”

ICELAND WARMS TO THE NET
A passion for exploration and a desire to become less isolated from the rest of the world has driven Iceland to the forefront of Internet connectivity. While 55 percent of Americans go online from home, work, or school, nearly 70 percent of the population in Iceland does so. Because the rest of the world rarely sees the island in the uppermost reaches of the Atlantic, the populace has been largely isolated from the world. Essentially, the Internet has enabled the country to join the global community. Prime Minister David Oddsson says Iceland must be connected to the world. In 1996, Oddsson was key in pushing legislation that set aside money for computers in classrooms and support for those interested in pursuing the high-tech world. Computers are now in almost every classroom in Iceland, and within the past five years about 200 information-technology companies have been created. In fact, tech entrepreneurs consider Iceland to be the ideal test market. Cost is a fraction of what it would be in the U.S., and one ad will attract the full attention of the nation's 270,000 inhabitants. Also, failure in Iceland will not be a major loss.

ONE SCHOOL'S QUANTUM LEAP
Daniel Jenkins Academy in Polk County, Fla., will become the nation's first school to offer students a completely online curriculum in a classroom, despite district level educators having doubts that such a system can be effective. Florida High School (FHS), which previously only served individual students, will be the subcontractor for Jenkins' online system. Although Jenkins principal Sue Braiman originally thought up the idea of an online school because of the space limitations involved with construction of the aging building, parents have been swayed to enroll their children because of the promise of small classes and individualized, self-paced education that lets students build their school days around their learning strengths. Parents' biggest complaints with the traditional school were discipline problems, overcrowding, overwhelmed teachers, and bomb threats interrupting classes. Although no teachers will be present in Jenkins' classrooms, students will still share lunch and hallway interactions. Students will also have the opportunity to do away-from-school projects, take field trips, and participate in extracurricular activities at a nearby high school.

GORE DENOUNCES DISPARITIES IN MINORITY ACCESS TO COMPUTERS
Addressing an audience of 500 students at Morehouse College, Vice President Al Gore called for government action to help bridge the digital divide in computer use between white and minority Americans. Gore urged the government to ensure that every student is computer literate by the eighth grade. Gore's proposals include Internet access for all schools and libraries, technology training for teachers, the full inclusion of computers in school curriculums, and the creation of computer learning centers in less fortunate communities. President Clinton has also called for many of these same initiatives. Several recent studies show that the digital divide threatens to widen racial gulfs in the areas of education, employment, and income. A Commerce Department study conducted last summer found that income differences alone cannot explain differences in computer use among different ethnic groups.
