In a conventional sewage works, nanoparticles should really be bound in the sludge and should not represent a major problem in the aqueous effluent. This is not true, however, as shown by a new study of the ceramic model material cerium dioxide.
Scientists seeking to protect the soldier of the future can learn a lot from a relic of the past, according to an MIT study of a primitive fish that could point to more effective ways of designing human body armor.
Japanese theorists show that a single beryllium nucleus can briefly resemble a covalently bonded molecule, an ionically bonded molecule, or just a pair of neutral atoms. It all depends on the energy with which two smaller nuclei collide to create the beryllium nucleus.
For years, human growth hormone has been considered one of the main banned substances used by athletes who want to build strength and avoid getting caught. Now a company in Virginia says researchers who originally set out to work on diagnosis and treatment of cancer have developed a test that can find HGH in urine, something one anti-doping expert believes 'could be a quantum leap forward' in the fight against drug use in sports.
Australia's regulatory systems are well placed to respond to the introduction of nanotechnology products. Two documents released this month identify areas for further work and the way the Government will address emerging nanotechnology issues.
The effects of a new class of molecules, polyoxometalates, which are primarily composed of metals and oxygen, has been identified. These molecules are very powerful inhibitors of a specific protein kinase, CK2, an enzyme that is overactive in a number of cancers.
Scientists at the University of Pennsylvania have created a one-step, repeatable method for the production of functional nanoscale patterns or motifs with adjustable features, size and shape using a single master 'plate'.
