— 30 Sep 2010 12:59 | HealthThe purification of drug components is a large hurdle facing modern drug development. This is particularly true of drugs that utilise proteins, which are notoriously difficult to separate…
Transition metal catalysts could be key to origin of life, scientists report
— 4 Sep 2010 10:51 | BiologyOne of the big, unsolved problems in explaining how life arose on Earth is a chicken-and-egg paradox: How could the basic biochemicals - such as amino acids and nucleotides - have arisen…
Mechanical regulation of cell substrates effects stem cell development, adhesion
— 2 Aug 2010 09:34 | HealthBioengineers at the University of Pennsylvania have created a system to control the flexibility of the substrate surfaces on which cells are grown without changing the surface properties,…
Blocking tumour's 'death switch' paradoxically stops tumour growth
— 27 May 2010 11:17 | HealthEvery cell contains machinery for self-destruction, used to induce death when damaged or sick. But according to a new research study, a receptor thought to mediate cell suicide in normal…
