Dust off those Bic ballpoints and college-ruled notebooks — research shows that taking notes by hand is better than taking notes on a laptop for remembering conceptual information over the long term. The findings are published in Psychological Science, a journal of the Association for Psychological Science.

Pseudomonas aeruginosa is a bacteria that commonly infects the lungs of cystic fibrosis patients, often with lethal consequences. A cationic antimicrobial peptide called LL-37 produced from neutrophils, one of the major cellular components of the innate immune response, can induce mutations in P. aeruginosa bacterial DNA that can paradoxically increase bacterial lethality. This is the major finding of a new study in the journal PLoS Pathogens from a team of researchers in different US institutions.

The smallest, most abundant marine microbe, Prochlorococcus, is a photosynthetic bacteria species essential to the marine ecosystem. An estimated billion billion billion of the single-cell creatures live in the oceans, forming the base of the marine food chain and occupying a range of ecological niches based on temperature, light and chemical preferences, and interactions with other species. But the full extent and characteristics of diversity within this single species remains a puzzle.

A newly identified disorder affecting the human nervous system is caused by a mutation in a gene never before implicated in human disease, according to two studies published by Cell Press April 24th in the journal Cell. By performing DNA sequencing of children affected by neurological problems, two research teams independently discovered that a disease marked by reduced brain size, as well as sensory and motor defects, is caused by a mutation in a gene called CLP1. Insights into this rare disorder may have important implications for the treatment of common disorders.

Researchers at UNSW have for the first time used electrical pulses delivered from a cochlear implant to deliver gene therapy, thereby successfully regrowing auditory nerves.The research also heralds a possible new way of treating a range of neurological disorders, including Parkinson’s disease, and psychiatric conditions such as depression through this novel way of delivering gene therapy.
