Return to Zambia MWV 17

submitted by: MicrobeWorld
The American Society for Microbiology is helping African nations foster a scientific community that is better able to address the current and future problems that threaten not only the local population, but the world at large. Like many African countries, Zambia and South Africa are deeply affected by HIV and tuberculosis, as well as a number of other infectious diseases. In March of 2008, ASM President Cliff Houston, Ph.D., traveled to Zambia and South Africa to gauge and assess the...

Methylphenidate Decreased the Amount of Glucose Needed by the Brain to Perform a Cognitive Task

submitted by: noravolkow
The use of stimulants (methylphenidate and amphetamine) as cognitive enhancers by the general public is increasing and is controversial. It is still unclear how they work or why they improve performance in some individuals but impair it in others. To test the hypothesis that stimulants enhance signal to noise ratio of neuronal activity and thereby reduce cerebral activity by increasing efficiency, we measured the effects of methylphenidate on brain glucose utilization in healthy adults. We...

open genius: strumento per una scienza libera

submitted by: atnp lab

In this presentation, Andrea Gaggioli describes crowd-funding as a possible strategy to cope with the lack of investments in research, as well as to increase democratization in the sciences. Projects seeking funding could be stored in an online repository. Each project would include a description of its objectives, duration, and requested contribution. Investors (either people or funding agencies) could decide which projects to fund.

Small Regulatory RNAs May Sharpen Spatial Expression Patterns

linked profile(s): hlevine
submitted by: apryl
The precise establishment of gene expression patterns is a crucial step in development. Formation of a sharp boundary between high and low spatial expression domains requires a genetic mechanism that exhibits sensitivity, yet is robust to fluctuations, a demand that may not be easily achieved by morphogens alone. Recently, it has been demonstrated that small RNAs (and, in particular, microRNAs) play many roles in embryonic development. Whereas some RNAs are essential for embryogenesis,...
