Shell creates nanofiltration water purification system for rural areas

Many Shell operations in rural areas have no safe drinking water sources nearby. So Shell sought a water purification unit that would provide safe water, be vandalism proof and be essentially maintenance-free, with low-skilled operators able to carry out the limited maintenance tasks necessary.

Quantum systems could flout physics law

Scientists in the Weizmann Institute's Faculty of Chemistry, together with colleagues in Germany, have made a startling prediction: Simply 'taking the temperature' of certain quantum systems at frequent intervals might cause them to disobey a hard and fast rule of thermodynamics.

Synergy between biology and physics drives cell-imaging technology

Developing techniques to image the complex biological systems found at the sub-cellular level has traditionally been hampered by divisions between the academic fields of biology and physics. However, a new interdisciplinary zeal has seen a number of exciting advances in super-resolution imaging technologies.

Research measures movement of nanomaterials in simple model food chain

New research shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level organisms.
