Weapons of Mass Confusion: Assessing the True Risks
Panelists gathered for this discussion agree that when setting weapons policy it is counterproductive to lump weapons together. The dangers from nuclear, biological, and chemical weapons need to understood individually. Owen Cote says nuclear weapons, with their large-scale production process and instant lethal capacity, belong in one categ

Survey on opinions from national bioethics committees or similar bodies, public debate and national
The European Commission, DG Research (Directorate E: Biotechnology, Agriculture and Food) devised a survey during the Spring 2001 in order to compile opinion-based data from national bioethics committees and current national legislation in relation to human embryonic stem cell research. The data would be used to structure an informative debate on stem cells across Europe. The survey has been updated regularly in accordance with the continual monitoring of the societal dialogue, the ethical consi
Started by Oxford Journals in 2009, AoB PLANTS is an online, open-access journal publishing papers on all aspects of plant biology, including palaeobotany, and covering micro-organisms and animals where their impact on plants is central. Papers are peer-reviewed before publication, after which readers are able to submit comments through the medium of E-LETTERS which provides a published exchange of views. NB There is as yet very little content in this journal.

Sci-tutors: Life Processes and Living Things: Cells and Cell Functions
The emphasis of this article is on the conceptual changes needed by learners (tutors, teachers and their pupils) to come to an understanding of living things. This covers the material useful at KS1-4, and provides access to the key ideas of the topic and provides suggestions for appropriate practical experiences to support learning.
Sci-tutors: Life processes and Living Things: Green Plants and Organisms
The article from the Sci-tutors website provides an outline of the expectations of the National Curriculum regarding green plants at Key Stages 1 - 4 and explores the various alternative conceptions held by learners.
Phase separation in solid solution upon cooling: vial projection
The vial containing a mixture of cyclohexane and aniline cooling from 35º, has been filmed perpendicular to the direction of the laser light (left to right). When the critical temperature is reached and the mixture goes from a single phase to two phases, the spot of light on the screen is disrupted as the phases separate. The spot 'flickers' and then becomes totally diffuse. It will eventually form a single spot again once the transition is completed and the two chemicals have completely separa
Phase separation in solid solution upon cooling: laser beam projection
As video "Phase separation in solid solution upon cooling: vial projection", but filmed looking into the laser light after it has passed through the vial (i.e. the video is of the laser beam as projected onto a screen): The vial contains a mixture of cyclohexane and aniline cooling from 35º. When the critical temperature is reached and the mixture goes from a single phase to two phases, the spot of light on the screen is disrupted as the phases separate.

Stem Cell Therapies are no More Drugs Than Soufflés are Fast Food
Stemcell discoveries make great news stories, but their actual translation into routine clinical practice is still a major hurdle. Is it reasonable to expect the big pharmaceutical companies to manufacture these living therapies or is the paradigm shift from today’s drugs to ‘living cells as therapies’ overwhelming? Would McDonald’s ever put delicate soufflés on their fast-food menus? This lecture will use examples from current cell and tissue-engineered clinical therapies to illustrate
