Chemical Aggregation
21. May 2007 08:35
Chemspy has added a new chemistry news
section to bring you the latest and greatest
chemistry newsfeeds from around the globe. This
is very much a "beta" project and the format and
feeds aggregated are likely to change as we
receive feedback on the new service. We are
currently aggregating five chemistry RSS feeds
from major news outlets. We are not scraping
blogs to create a splog, but are using the
format of really simple syndication (RSS) to
provide visitors with a single entry point to
chemistry news. If you know of a newsfeed you
think we should aggregate in this service,
please let us know at office@chemspy.com.nospam.
If you would like to subscribe to our meta feed,

Organic Lectures Reach Drexel Island
16. May 2007 17:17
Jean-Claude Bradley at Drexel University has
taken his second life persona to his
professional bosom and is now providing organic
chemistry students not only with obelisks on the
dragon-shaped island of Drexel (Drexopia,
perhaps?), but they can now see orgaic chemistry
lectures there too. It is an incredibly
innovative use of SL, but I wonder whether
students are going to feel like they are being
monitored not only in the real world of
university lecture rooms and study areas, but in
the escapist virtual spaces of SL too. Scary
thought.
DBPedia for Chemists15. May 2007
14:01
Cambridge chemist Peter Murray-Rust recently
alerted me to the DBpedia service. DBpedia.org
is a community effort to extract structured
information (semantics) from Wikipedia and to
make this information available on the Web.
DBpedia allows you to ask sophisticated
questions of Wikipedia rather than carrying out
simple searches. "DBPedia is a semantic
distillate of Wikipedia and soon all the
chemistry will be in semantic form," asserts
Murray-Rust, "It will then be possible to ask
questions like: "find compounds which were
discovered by a Russian chemist in the 19th
Century". That is a simplistic example, of
course. He believes that such efforts form part
of a new information philosophy of "linked data"
and points out that Open chemical resources,
such as Pubchem, DBPedia, CrystalEye, ChEBI,
etc. will soon become part of that philosophy.
InChI Hash10. May 2007 13:27
You may have noticed the advent of strings of
alphanumerics appearing on chemistry blogs such
as
Spinneret Chemistry News and many chemistry
journals recently, they are also abundant in the
chemistry databases including PubChem, ChEBI,
and ChemSpider. Apparently, the average length
of an InChI string, which uniquely represents a
single molecule, is about 146 characters. Such a
string length can often be too long for many
search boxes, which limit entries for security
reasons, and also causes serious spillover in
blogs and publication pages. Thankfully, IUPAC
has come up with a proposal to create an InChI
hash. A standard-length codified version of the
InChI format that might also embed a checksum
character to ensure integrity. Such an InchiHash
discussed by Rich Apodaca on Depth-First could
quickly lead to the widespread of adoption of
the invaluable InChI format. Watch this space.
Sex attractants08. May 2007 08:35
Apparently, the most commonly searched
molecular structures lie among those compounds
found in the drug discovery field of ED.
According to Antony Williams at ChemSpider.com
viagra, cialis and levitra are searched again
and again. "How many of these searches are by
lay people and how many by chemists?" he asks,
If these searches are by non-chemists what are
they trying to find out about these chemicals at
ChemSpider? Are they looking for side effects,
consumer reports, suppliers or prices? It could
prove a lucrative avenue of funding for the
site, which by Williams own admission, is
currently running mainly on devotion and
adrenalin.
Journal Greasemonkeys02. May 2007
13:15
Greasemonkey is a Firefox scripting device
that allows you to hack (within the browser
window), the layout and format of a website you
are visiting. Do not worry it does not touch the
actual pages, just your view of them. Now, Noel
OBoyle has posted on the PMR blog about a new
Blue Obelisk greasemonkey that allows you to see
what bloggers are saying about a particular
journal article, while you are browsing the
journal table of contents. If you want to see
any other journals added to the list, post a
comment on the PMR blog.
Almost Visible Nanotubes03. May
2007 14:13
You might think that an 18mm long
single-walled carbon nanotube would somehow be
visible to the naked eye. Well, naked or not
your eyes simply cannot resolve objects that are
mere nanometres across, regardless of their
length. So, what have SWNT's got to do with
chemical informatics, searching and databases?
Well, only insomuch as they are being touted as
the future cabling and devices for molecular
scale computers.
Charitable Status of OA25. Apr
2007 13:59
Supporting OpenAccess? Fashion conscious
scientist? Feel like giving to charity but want
something in return? Then check out BMC's range
of attractive tee-shirts emblazoned with their
various logos. On his blog, Cambridge U coding
trombonist Jim Downing, says that the
merchandising approach is probably not a good
business model for OA because the money goes to
charity, but according to the BMC site a mere 2
euros from a 27.40 euro tee-shirt is going to
Computer Aid International. I'd be more inclined
to buy a white tee-shirt from Oxfam, print my
own logo and give the remainder of the cost to
the charity direct.
Nobel Prize in Chemistry 200722.
Apr 2007 19:07
Paul at the fabulous ChemBark blog (not so
sure about the dog-cat hybrid with benzene in
its eyes) is laying down odds for this year's
Nobel chemists. At 15:1 he reckons Molecular
Studies of Gene Recognition (Ptashne) and
Nuclear Hormone Signaling, Chambon/Evans/Jensen.
So basically molecular biology rather than
chemistry. Longest odds are Molecular Machines,
Stoddart/Tour/+/– at 499-1 and then Studies in
the Origin of Life, Miller/Orgel/+/–, 99999-1.
Obviously Miller and Orgel will never, but I'd
have put my good friend Sir Fraser at much
shorter odds than 499-1. In fact, I've been
tipping him as my hot tip for the last decade at
least and now that he's a knight of the realm
isn't it time he got his invitation to
Stockholm? I think so.
Molecular Passwords18. Apr 2007
13:26
A few weeks back I came up with what I think
is perhaps a simple but potentially
uncrackable passwords, especially for
chemists. You will have to visit the Sciencetext
site to find out more, but in the meantime, you
should install
Chemspider Search for Firefox to help you
come up with inspiration.
Depth of Feeling
13. Apr 2007
Depth-First is not a new blog, at the time of
writing the site, which is apparently "walking
the web of chemical informatics" has archives
stretching back to August 2006 and some 121
posts. A nice tag cloug gives you an idea of
their content - inchi, 2d, cdk, opensource,
ruby, pubchem, and with popular posts on hacking
PubChem, free chemistry databases, the
aesthetics of chemical structure diagrams, and
converting IUPAC names to molecular formula with
Ruby CDK it is quite likely that this blog will
continue to grow in strength and populaity.
QSAR Love
5. Apr 2007
ChemSpy's good friend and cheminformatician
Wendy Warr emailed to alert us to a new resource
for drug discoverers - http://www.qsarworld.com
for which Dr Warr is a member of the Editorial
Advisory Board.
QSAR World is a free, comprehensive web-based
portal for the Quantitative Structure Activity
Relationship (QSAR) modeling community and
offers a free forum to share ideas and knowledge
via articles, posters and datasets.
Chemists invade second life
1. Apr 2007
The team at the UsefulChem blog have invaded
virtual reality world Second Life. Apparently,
they've already dug a cemetary and filled it
with blue obelisks (don't ask...it's for organic
chemistry class quizzes) and are working with
fellow SL'ers on a virtual molecular gallery
that allows others to walk around compounds,
such as cholesterol. You can discover more by
following this slurl
There's a new chemical search engine on the block. The ChemSpider search, has access to 10million+ molecules and growing and is structure and substructure enabled. If you have ChemSketch from ACD/Labs, you'll have the perfect tool in hand for accessing the database.
If you're a chemical physicist, a physical chemist, or just a plain vanilla physicist, you will almost certainly know about the arXiv preprint server. Well, as of this summer, arXiv will have built-in anti-plagiarism software, so just make sure all your words are original before you submit.
My good friend Mitch Garcia at Berkeley is a great proponent of Yahoo Pipes, the relatively new system that allows you to create sophisticated search algorithms based on RSS feeds (for search results). I asked him to look into creating a Pipe to allow anyone to search all the chemistry journals for ASAP papers, so here it is, give it a try and let us know what you think. The really useful part of creating such a pipe is that once you carry out a specific search, the results produce their own rss feed as output, which you can subscribe to in your newsreader as you would with any normal rss feed.
For those who haven't already heard MIT has made hundreds of its course available online in various forms. This item links to the Chem Eng section but there are so many more.
Chemindustry.com reports that the infamous IUPAC Gold Book has finally been brought into the 21st Century and is now taking "full advantage of new technologies based on eXtensible Markup Language (XML) and provides efficient ways of browsing, searching, and simply using this reference." We'll be updating our Gold Book search tool shortly.

BioRails is a new open source study & test management solution designed for biologists working in drug discovery research. It has been specifically designed to support biologists working in in vivo and therapeutic research areas.
A new open access outlet for chemists? peer reviewed research was launched today. Chemistry Central Journal. Publisher BMC says, the journal is the first international open access journal covering all of chemistry and will publish its first issue early in 2007.
The top searches on Chemspy reflect some of the fairly obvious interests of our readers as well as some of the more esoteric: imidacloprid formulations, anthracene, sulfuric acid, basic information of stereospecific compound, m-CPBA, terpenoids, Dynacco Inc, Polyvinyl Alchohol manufacturer, stoichiometry lab activity, chemical prices, ammonia, imidacloprid solubility, naphthalene, methanol, isooctanol, ketanserin, stoichiometry/labs, metformin, trichloromethane... The list goes on. At some point we may produce a page to point to detailed information on each of these. In the meantime, feel free to use our specialist search engines such as chemindustry.com, pubchem etc and of course Chemspy's own internal search facilities.
Chemspy was featured as a "Nice Web Site" this month by the Internet Resources Newsletter. "There's a great deal of information available through this site...All databases included in this service are free of charge and available without login". So, there you have it. Take a look at http://www.chemspy.com for all your chemical info needs.
We've upgraded the Chemspy chemical search page to purge obsolete search tools and to update the system. Give it a try, you can search for chemical prices, chemical companies, MSDS data sheets, chemistry journals, patents, dictionaries, acronyms, spectral data, physical properties, chemistry jobs, and more.
A new Open Access chemistry portal launches today. We will be keeping a close eye on how the system progresses and keep you informed of updates as well announcing the imminent launch of the organisation's new chemistry journal. Read the press release and commentary from David Bradley in the Sciencebase scienc blog.
We're now running the RSC's Chemistry World newsfeed on the ChemSpy site, to provide you with the latest breaking news from this award-winning magazine.
According to Steve Heller, writing in CHMINF-L, the recent addition of chemical structures from Spain's Prous Science's Drugs of the Future database, and additional structures from the NIH-funded UC-SF ZINC project now means the open access PubChem chemical structures database containes almost 8 million unique chemical (7,995,841 at the time of posting). You can search PubChem direct from your favourite chemical database and search site ChemSpy.com right now, for free.
Now you can search the full-text scientific literature from dozens of publishers courtesy of Google. We have embedded the appropriate tags on this test page. Enter your search term and hit Go. The results returned will filter out those you'd get from a normal web search and give you journal articles from each publisher site with the convenience of a single 100-entry search engine results page (SERP)
If you're called Frank, Nina, Tiberius, Asimov, Nicholas, or Hepburn, and you're a chemist, you're probably well aware that you can construct your name from periodic table element symbols, e.g. AsIMoV (arsenic, iodine, molybdenum, and vanadium), or if you're not that way inclined you may not have tried this periodic game with your monicker. Chemspy now presents a periodic table compliancy test for all visitors, c/o VIReN over at viren.org. Check it out! It's fun and if you can't remember your own name, pick your favorite movie or pop star, or a well-known chemist! The periodic table name game featured in SEED magazine's Daily Zeitgeist on June 27th.
Chemspy now brings you regularly updated listings of forthcoming chemistry conferences and meetings, chemical symposia, and industry trade shows and other events.
We've made a few changes to the site's front page, giving our what's new section it's own box, adding the free chemistry magazines portal, and running the chemistry blog headlines too. We've also adopted the new ChemRefer search standard for speedier searching of the open access chemical literature and switched our Chmoogle references to their new name - e-Molecules. We've also fixed some minor niggles such as the failure of our science events page to render, this has been repaired now. Visit soon and find out what's new in chemical searching!
You'll need Java enabled to work this chemical machine, but visit http://intro.chem.okstate.edu/1314F00/Laboratory/GLP.htm to have a play with the Gas law Program. Basically, lots of little green dots bouncing around, move the sliders to change temperature, pressure and volume and find out what happens when you squeeze or heat a gas. It's an oldie but a goodie.
Sadly, a higher power has decreed that the chemical search engine Chmoogle not be called -oogle any more. Can you guess who brought the suit against them? No? Really? So, now Chmoogle is eMolecules, and the group of scientists who run the site have decided not to fight on even though they think they're right. You can still search Chmoogle, sorry eMolecules, through the Chemspy tools. I'll await the final outcome before switching over to the new name...
A query on the Sciencebase.com site regarding whether it were possible to reverse engineer a high-resolution molecular weight to work out a likely molecule with that particular weight with no additional information sent me on a search for an appropriate tool. Thanks to Jonathan Goodman at the University of Cambridge I discovered that just such a tool does indeed exist. Now with Jonathan's permission we are enabling the tool on the ChemSpy site.
