Welcome to AccessScience News!
AccessScience News, based on the McGraw-Hill Encyclopedia of Science and
Technology Online, is a free monthly citation of current science updates
available on AccessScience. Our goal is to keep you abreast of the
newest content and features of AccessScience.=09

<http://www.accessscience.com/Newsletter/images/NewNoteworthy.gif> =09
Product enhancements make using the site even easier, from wherever you
login.=20
* Every article is now linked to an active digital object
identifier (DOI), in addition to its URL. On the Internet, the DOI
functions as a kind of persistent "super-URL," linking users directly to
where they can view an item, learn more about it, find related items,
access related services, and more. DOIs will help World Wide Web users,
particularly students and others using public search engines, find
relevant AccessScience content. For example, AccessScience articles are
rising in the Google=99 rankings due to the DOI. Users finding links to
AccessScience article previews with Google=99 should be aware that they
will have full access to articles through their library subscription.=20
* A search engine upgrade is now underway. The upgrade will make
searching content even easier with re-organized search results and
improved speed. Starting in August, a preview of the new search engine
will be available to users along with the current one. We will welcome
your feedback and the opportunity to address any questions or comments
you may have.=20
AccessScience content continues to grow over the summer months.
* The first installment of the animated series, AccessScience
Visual Learning Modules, is now online. Exclusive to AccessScience, DNA
Replication is an animated, click-and-view learning module and the first
of the series in genetics: DNA, RNA, and protein synthesis. Look for the
animation icon in the articles Genetics
<http://www.accessscience.com/server-java/Arknoid/science/AS/Encyclopedi

* Active
<http://www.accessscience.com/server-java/Arknoid/science/AS/Encyclopedi
a/0/01/Est_010025_frameset.html> sound control, by Prof. Philip A.
Nelson, Institute of Sound and Vibration Research, University of
Southampton, England. Active sound control involves the modification of
sound fields by using additional sound transmitted from loudspeakers,
for example in order to control noise. This well illustrated article
surveys the physical principles of active sound control, applications of
digital signal processing, and multichannel systems.

* Biotic
<http://www.accessscience.com/server-java/Arknoid/science/AS/ResUpdates/
2004/YB_040450_frameset.html> recovery after mass extinctions, by Dr.
Paul B. Wignall, School of Earth Sciences, University of Leeds, UK. The
causes of mass extinctions during geologic history have been the subject
of much research and debate. But now interest is also focusing on what
happened after such extinctions, especially since this can help us
understand the consequences of modern environmental disruptions. This
article surveys extinction, survival, and recovery in aquatic and
terrestrial systems as well as "the message from the past."

<http://www.accessscience.com/server-java/Arknoid/science/AS/ResUpdates/
2004/YB_041215_frameset.html> (biology), by Prof. Trevor M. Letcher,
Department of Chemistry, Natal University, Durban, South Africa This
article provides an overview of the thermodynamics of heat-producing
reactions in the metabolism of organisms ranging from microorganisms to
invertebrates to humans.

* Mobile-phone
<http://www.accessscience.com/server-java/Arknoid/science/AS/ResUpdates/
2004/YB_041040_frameset.html> antennas, by Prof. J. (Yiannis) C.
Vardaxoglou, Department of Electronic and Electrical Engineering,
Loughborough University, UK. Mobile (cell) phones have steadily
decreased in size as a result of strong consumer demand, and the design
of their antennas have followed suit. With the help of explanatory
diagrams, this article reviews design considerations in the reduction of
antenna size and visibility; reduction of user irradiation; and
development of antennas with near-field control.

* Nanosatellites
<http://www.accessscience.com/server-java/Arknoid/science/AS/ResUpdates/
2004/YB_041170_frameset.html> , by Prof. Donald Platt, Spaceport
Graduate Center, Florida Institute of Technology, Satellite Beach.
Nanosatellites, defined as having a mass of less than 10 kg (22 lb), are
being studied and developed by various space agencies and commercial
organizations. This colorfully illustrated article introduces the
possible applications of nanosatellites (e.g., missions requiring a
"swarm" of small satellites), systems development, and usage by "small"
organizations, such as universities.

* Parallel
<http://www.accessscience.com/server-java/Arknoid/science/AS/ResUpdates/
2004/YB_040425_frameset.html> computer processing in systematics, by Dr.
Ward C. Wheeler, American Museum of Natural History, New York, Dr.
Daniel Janies, Department of Biomedical Informatics, Ohio State
University, Columbus, and Dr. Jan De Laet,Royal Belgian Institute for
Natural Sciences, Brussels. Advances in DNA sequencing have created huge
quantities of genomic data that are available for studying fundamental
questions about taxonomy and biological diversity. Analyzing these data
is especially complex, and systematists have turned to powerful parallel
processing computers for this task. This article reviews this field,
focusing on DNA sequencing alignment, principles and applications of
parallel computing to systematics, and computer clustering.

* Plant
<http://www.accessscience.com/server-java/Arknoid/science/AS/ResUpdates/
2004/YB_040335_frameset.html> pathogen genomics, by Dr. Blake C. Meyers,
Department of Plant and Soil Services, University of Delaware, Newark.
The addition of genomics to the toolkit of molecular biology has
dramatically increased our understanding of how plants interact with
disease-causing microbial organisms and our ability to develop
strategies for combating plant disease. This article reviews the genomic
analysis of bacterial, viral, and eukaryotic pathogens and surveys plant
defense and immune systems.

* Scramjet
<http://www.accessscience.com/server-java/Arknoid/science/AS/ResUpdates/
2004/YB_040735_frameset.html> technology, by Dr. Joaquin H. Castro,
Pratt and Whitney, West Palm Beach, Florida. The author tells us that
traveling from New York to Sydney in about 2 hours or spending a weekend
at the Space Station or the Moon may sound like science fiction, but
supersonic combustion ramjet (scramjet) technology in development today
is expected to make global rapid travel and affordable orbit access a
reality within the next 25 years. He then reviews how scramjets work,
their advantages, development, operation, and outlook for the future.
