|Virtual Textbook of Organic Chemistry|
|William H. Reusch, emeritus professor at Michigan State University, published his Introduction to Organic Chemistry in 1977. Readers may purchase it for a list price of $137.74; or they may access the Virtual Textbook of Organic Chemistry, which contains nearly the same information online, for free, on this surprisingly comprehensive website. Here readers will find a fully operational organic chemistry textbook, divided into the two overarching topics of General Principles and Functional Group Reactions. Within General Principles, readers will learn the basics of Structure & Bonding, Intermolecular Forces, Chemical Reactivity, Aromaticity, and other subjects. Functional Group Reactions covers Alkanes, Alkenes, Alkynes, Alcohols, and many other subjects. For readers looking for a comprehensive, freely available organic chemistry textbook, this site will be a true boon. [CNH]”

Arctic Matters day, according to the National Research Council of the National Academies is January 14th. Go to http://nas-sites.org/arctic/ to read about it. Link to their Interactive web tool, or download a PDF of their 32-page, well-illustrated booklet or download a poster. What happens in the Arctic, affects the whole globe.

Poisonous Plants Database
The people in the College of Agriculture and Life Sciences at Cornell University want to make sure that you don’t accidentally poison your livestock or pets with toxic plants. Their Poisonous Plants database includes a sizable number of entries such as oak trees (the acorns and young leaves are poisonous to horses and cattle), Daphne (toxic to cats, dogs, and humans), and rhubarb (the leaves are toxic to goats, swine, horses, and even people—who knew?). Each entry is accompanied by images of the plants, as well as answers to questions that the authors have either encountered in the past or anticipate that readers may have. The database is simple to browse—either by scientific name or common name—or users can search the database by scientific name, common name, primary poisons, or species most often affected.

Summary: A group of unusual giant black holes may be consuming excessive amounts of matter, according to a new study. This finding may help astronomers understand how the largest black holes were able to grow so rapidly in the early Universe.”
A group of unusual giant black holes may be consuming excessive amounts of matter, according to a new study using NASA’s Chandra X-ray Observatory. This finding may help astronomers understand how the largest black holes were able to grow so rapidly in the early Universe.

“National Science Foundation YouTube Channel
Nearly 13,000 viewers have subscribed to the National Science Foundation’s YouTube channel. It’s not a secret why. These well-produced and often poignant presentations have managed to pack so much into such a small space. Nearly all the videos clock in at less than four minutes. Many of the clips are just two or three minutes long so readers can easily learn about the birth of planets, the details of the tropospheric ozone, and the wonders of biomedical engineering – all within the timespan of a quick coffee break. The hundreds of available videos are broken into categories such as Computer Science, Brain Research, and Education, among others. Whether you are looking for an interesting tidbit to add to your lecture on Geoscience or you are simply curious about conservation efforts in Central Africa, there is much to enjoy here. [CNH]“

From today’s WhatsNew@National-Academies.org:
Engineering Schools throughout the U.S. are committing to educate certain numbers of engineers with special interests and talents in helping to solve our greatest challenges.
“In a letter of commitment presented to President Obama today, more than 120 U.S. engineering schools announced plans to educate a new generation of engineers expressly equipped to tackle some of the most pressing issues facing society in the 21st century. Read More”

“Sure, the year 1941 may best be remembered for being the year of the attack on Pearl Harbor, but it was also the year in which X-ray diffraction patterns were obtained for the tomato bushy stunt virus (TBSV) and tobacco mosaic virus (TMV). You can find this and other world history/structural biology history side-by-side comparisons in the nifty timeline feature on the Viruses: From Structure to Biology website. This site—the creation of Sondra and Milton Schlesinger at Washington University School of Medicine —provides some nice background on key milestones in structural virology and the resulting biological breakthroughs in the field. There isn’t a ton of information on the site—one might call it a single-serving website—but within that serving you’ll be able to chew on some interesting science history.”
