Malaria Parasite Diversity Three studies independently characterize the genetic diversity of the parasite that causes malaria.
Scientists Share Thoughts On Animal Research An anonymous online poll of nearly 1700 researchers has revealed intriguing insights into scientists' views on the use of animals in research.
Cellular 'Dustbin' Modelled A detailed model of the phagosome, the cellular 'dustbin' that engulfs and destroys foreign matter, is unveiled.
Protein Blocks Brain Tumour Growth A protein that blocks the growth of aggressive human brain tumours in a mouse model has been identified.
Navigating The Mouse Brain The comprehensive digital map of gene expression in the mouse brain will have an impact on the fields of neuroscience and mammalian genomics alike.
Carbon Dioxide Receptors And Malaria The discovery of a pair of receptors that enable fruit flies to sense carbon dioxide (CO2) could boost the development of a new type of mosquito repellent.
Molecular Genetic Analysis Of The Human Dihydrofolate Reductase Gene Subjects were screened for the 9-bp repeat (n=417), as well as the recently reported 19-bp deletion in intron 1 (n=330) of the human dihydrofolate reductase (DHFR) gene, and their associations assessed with plasma tHcy, serum and RBC folate levels.
Novel Experimental Melanoma Treatment Combining an antibody with radiation shows promise for melanoma treatment and is expected to enter early-stage human clinical studies in 2007.

Auditory Repetition And Dyslexia Study reports that some dyslexic individuals have trouble encoding regularities in repeated sets of sounds.
An Unexpected Mechanism Of Pain A naturally produced pain reliever can exacerbate certain pain states rather than attenuate them in rodents.
High Times For Memory The active ingredient in marijuana -- tetrahydrocannabinoid or THC -- interferes with synchronized activity between neurons in the hippocampus of rats.
Fast 3D Imaging Of Brain Cell Networks A method of fast scanning microscopy that allows in vivo imaging of signalling in neuronal and glial cell networks is reported.
New Antibacterial Targets? Small molecules that bind to segments of RNA called riboswitches could represent a novel class of antibiotics.
Mycobacterium Tuberculosis Copper Regulator Found Scientists have discovered a protein that controls gene expression in response to copper in the bacterium that causes most cases of tuberculosis and potentially a wide variety of other bacteria.
How Primary Tumours Prepare Lung For Invasion Primary tumours prepare the lung for invasion by inducing factors that guide migration of both inflammatory and tumour cells to the lung.
Cell Senescence Cancer Link Researchers now think they know why in the early stages of many cancers, the activation of certain tumour-forming genes goes hand-in-hand with cellular senescence.
Words Roll Onto The Tongue People with synaesthesia - a 'crossing' of the senses - who can 'taste' words, begin to experience the taste sensation even before the word is actually spoken by them.
Drug Promise For Renal Disease Study suggest that the drug (r)-roscovitine that alters renal cell proliferation may prove a useful treatment for polycystic kidney disease.
