The US Presidential Order imposing travel restrictions is of deep concern to the international scientific community.
Many expressions of concern emerged from the scientific community in the wake of Presidential Executive Order 13769, ‘Protecting the Nation from Terrorist Entry into the United States’, signed by President Donald J. Trump on 27 January 2017. Among them was a statement on 3 February issued by the American Chemical Society, discussing the ‘chilling effect this order may potentially have on the freedom of scientific exchange among scientists and students worldwide’.

I have been to Timor Leste twice, in 2015 and 2016. In 2016, I met with Professor Samuel Venancio de Sousa Freitas, Dean of the Faculty of Science at the National University of Timor Leste. He is a chemist and is keen to form a Timor Leste Chemical Society (TLCS) and to participate in regional activities through the Federation of Asian Chemical Societies. I have been helping him to set up the society.
Overcoming hydrogen alloy embrittlement
Next-generation steel and metal alloys are a step closer to reality, thanks to an international research project involving a University of Queensland scientist.
Cobalt, a naturally occurring mineral that can also be an environmental pollutant, has been recorded in the blood of Queensland turtles at potentially harmful levels.
Researchers at the University of Warwick, UK, have witnessed – for the first time – cancer cells being targeted and destroyed from the inside, by an organo-metal compound.
Dave Sammut speaks to Caltech professor Frances Arnold, who is ‘using biology to do chemistry’.
‘I signed up for chemistry, not mathematics’ is a common complaint among chemistry students, especially at first-year undergraduate level, but also at senior secondary level and TAFE. Chemistry teachers and educators have observed that today’s students have less confidence to handle numerical calculations then their counterparts 20 years ago.
A century ago, amongst military conflict and political change, chemistry in Australia and around the world was making its mark.
It's almost impossible to pick up a scientific publication at the moment without reading something about graphene or one of its carbon cousins, including nanotubes and buckyballs. Graphene itself is simply an individual layer of the common mineral graphite – the black material in pencil lead – pure carbon atoms bonded together in an ultrastrong hexagonal pattern.
Self-assembly around metal ions
Scientists at the University of Manchester have produced the most tightly knotted physical structure ever known – a scientific achievement that has the potential to create a new generation of advanced materials.
The Professional Scientists Employment and Remuneration Survey is an annual snapshot of remuneration including base salary and other benefits across sectors, responsibility levels, years of experience, job functions, industries and branches of science.
Despite numerous studies, our standards of evidence for drugs in relation to driver impairment still fall behind those for alcohol and fatigue.
