“This image sparked scientific debate when it was released last year, with researchers arguing over whether newly forming planets were responsible for gaps in the dust and gas swirling around the young star.”

“University of Toronto, May 5, 2015.  Summary: A recent and famous image from deep space marks the first time we’ve seen a forming planetary system, according to a study by astrophysicists. The team found that circular gaps in a disk of dust and gas swirling around the young star HL Tau are in fact made by forming planets.”

arXiv hits 1 million submissions

From the “Cornell Chronicle”, Jan. 15, 2015, and seen in the “Fast Facts” column of “College & Research Libraries News”, Vol. 76(2)  p. 108, Feb., 2015,

“As an open-access service, it allows scientists from disciplines encompassing physics, statistics, computer science and others to share research before it’s formally published. One million papers have now been uploaded to the repository.”

“arXiv received more than 97,000 new submissions in 2014. More than 150 subject experts from around the world evaluate and categorize every article posted on arXiv.”

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.

    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]

    The Center for the Advancement of Science in Space (CASIS) is a non-profit organization that was founded in 2011 to manage the International Space Station. In addition to making access to the station faster and easier, connecting funders to scientists, and making research accessible to the public, CASIS hosts an excellent website packed with information about the space station. Readers may view the short videos on the homepage for more information on the projects CASIS sponsors, or peruse articles under the News & Events tab. Perhaps the most interesting part of the site, however, are the three tabs set aside for researchers, businesses, and educators. In fact, the For Educators tab is especially helpful, as it features Lesson Plans on topics such as “The Laws of Newton” and “Tracking Satellites,” a Q&A section, and Additional Resources for teachers.

    “Current Awareness Services have been published by libraries for a long time. They usually include new books, table of contents alerts, blogs, citation alerts, and other information. JournalTOCs builds on the idea by offering tables of contents (TOCs) for the newest issues of thousands of academic journals via this free website. Readers may type in the name of any journal in the search function on the homepage to access that journal’s latest table of contents. They may also browse by publishers and subjects. For librarians, students, and scholars who want to keep up to date on the breaking research in their field, this is a valuable resource. [CNH]

A very complimentary review by –J. N. Jeffryes, University of Minnesota

“Scopus’s nearest competitor is Web of Science http://thomsonreuters.com/thomson-reuters-web-of-science/ (CH, Jan’11, 48-2436), and the two tools remain somewhat complementary.  For post-1996 information, Scopus comes off as the more impressive of the two with its advanced citation analysis visualizations, wider inclusion of conference papers, and adoption of alternative impact metrics.  Because the citation counts and h index calculations go back only to 1996, Web of Science has the historical edge.  In the areas of interface design and record readability, Scopus is the stronger tool.  It provides an intuitive search format to explore an impressively broad base of research; if the depth of coverage were expanded (or as 1996 becomes more distant), this tool would become even more valuable.  Even as it is today, it is a very valuable resource for academic and professional libraries. Summing Up: Highly recommended. Upper-division undergraduates and above”
