Royal Institution Christmas Lectures
For those of you with access to Channel 4 in the UK, here is information about the The Royal Institution (RI) Christmas Lectures. See here for details of the 2015 lectures: how to survive in space.
Dr Kevin Fong opens a window onto today’s most exciting space missions, explores the future of space travel, and offers a unique insight into the challenges of protecting human life in the hostile environment of space in the 2015 Christmas lectures.

How to Name New Chemical Elements
IUPAC have modified provisional recommendations for naming new elements as follows:
A procedure is proposed to name new chemical elements. After the discovery of a new element is established by the joint IUPAC-IUPAP Working Group, the discoverers are invited to propose a name and a symbol to the IUPAC Inorganic Chemistry Division. Elements can be named after a mythological concept, a mineral, a place or country, a property or a scientist.

Interacting with molecules on the WWW
There are many chemical web pages that display chemical structures within the web page itself. You, the viewer can then rotate the molecule on screen, read off bond lengths and angles, and do other useful things. To do this, a free piece of software known as a plug-in is required. There are at least two plugins available for you to use.

WebElments and interactive spectra
WebElements now has the capability for authors on the site to embed easily interactive spectra using the JSpecView applet via bbcode using jspecview tags. This is achieved by writing:[jspecview=600,400]pclanilIR.jdx[/jspecview].
The =600,400 bit gives the desired spectrum size while the file name to be displayed is included between the tags. The file is uploaded by authors who are assigned rights to upload attachments.

Interactive molecules via Jmol
This site now has the ability to display molecules interactively via the Jmol Java applet. This should mean that some stories or articles may come to mean a little more. As an example:[jmol=300]H3N-BF3.mol[/jmol]The motivation for this came from CHMEMCONF Spring 2006 and in particular Bob Hanson’s paper. With Bob’s encouragment, what I’ve done here is made a small extension to the software I’m using here (Drupal so that molecules can be embedded simply with a bbcode type string, in this case: [jmol=300]H3N-BF3.mol[/jmol]I’ll

JSmol molecule viewer
This is for web authors.
Have a look at JSmol where you can find information about the JSMol molecule viewer. With this you can publish chemical structures in your web pages and it usually works just fine provided your viewers have fast access to the internet. For an example of JSmol in action try this VSEPR tutorial.
Quote: “JSmol is a JavaScript framework that allows web developers to create pages that utilize either Java or HTML5 (no Java), at will.

Spectroscopy of element 115 decay chains
A paper accepted Aug 2013 and published in September 2013 entitled Spectroscopy of element 115 decay chains by D. Rudolph et al. provides additional evidence for element 115.1
Abstract
A high-resolution α X-ray and γ-ray coincidence spectroscopy experiment was conducted at the GSI Helmholtzzentrum für Schwerionenforschung. Thirty correlated α-decay chains were detected following the fusion-evaporation reaction 48Ca + 243Am.
