Touret et al., "Quantitative and dynamic assessment of the contribution of the ER to phagosome formation," Cell, 123:157–170, Oct. 7, 2005.Aligning an impressive array of methods, this study provides strong evidence against the recently proposed model of a significant contribution of endoplasmic reticulum (ER) membranes during early phagosome
Worms learn: If something makes you sick, don't eat it again.
Scientists have identified a candidate taste receptor for lipids.
Neuronal cells clogged with a mutant protein associated with amyotrophic lateral sclerosis (ALS) die within hours after clumps first form, researchers report.1 The finding directly links aggregation of malformed proteins with cell death characteristic of the disease, the authors claim.By watching individual cells over the course of 48 hours, Richard Morimoto at Northwestern University and colleagues demonstrated that most cultured neurons die between 6 and 24 hours after mutant superoxide dismut
Using a novel bioinformatics approach, researchers identified a gene fusion that seems to occur in a majority of prostate cancers.
Dope may help the growth of new brain cells.
Take the bully out of the schoolyard and another quickly takes his place.

O'Doherty et al., "An aneuploid mouse strain carrying human chromosome 21 with Down syndrome phenotypes," Science, 309:2033–7, Sept. 23, 2005.This is the first study to show that a human chromosome can be introduced into a mouse's germline and transmitted to successive generations. The authors introduced a copy of human chromosome 21. The mice
Jamming the epidermal growth factor (EGF) receptor allows severed neurons to regenerate.1 "It's a surprising finding," says Martin Schwab of the University of Zurich, as activation of the EGF receptor is normally associated with proliferation and growth of cells.Previous research that sought to explain why mammalian axons fail to regenerate in the wounded brain or spinal cord found several inhibitory cues that prevent healing. The culprits include proteins associated with myelin and proteoglycan
