Rethinking proteasome evolution: two novel bacterial proteasomes.

drnknmstrr — Mon, 11 Aug 2008 16:41:39 -0700

The proteasome is a multisubunit structure that degrades proteins. Protein degradation is an essential component of regulation because proteins can become misfolded, damaged, or unnecessary. Proteasomes and their homologues vary greatly in complexity: from HslV (heat shock locus v), which is encoded by 1 gene in bacteria, to the eukaryotic 20S proteasome, which is encoded by more than 14 genes. Despite this variation in complexity, all the proteasomes are composed of homologous subunits.

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

noravolkow — Thu, 22 May 2008 14:36:31 -0700

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.

WSM - Wave Structure of Matter - Overview

RayTomes — Thu, 06 Mar 2008 14:06:03 -0800

WSM is used to mean the concept of matter really being fully explicable as spherical standing wave structures. By studying the possible actual structure forms we can understand how de Broglie's results make perfect sense and be in the company of de Broglie and Shroedinger who held to this view rather than one based only on probabilities.

The longest geological cycle identified is described as about 600 million years in "Megacycles", the proceedings of a geological conference, Edited by G Williams. However Prof S Afanasiev of Moscow has determined the cycle very accurately to be 586.24 million years using his Nanocycles Method.

Galaxy-Quasar Associations: Is the Big Bang Bung?

RayTomes — Fri, 22 Feb 2008 12:35:43 -0800

When we see a galaxy and a quasar near each other in the sky, it might be because they are really near each other, or it might be that they are far apart and just along the same line of sight. Tests performed by Alan Stockton (Astrophysical Journal 223:747-757, "The Nature of QSO Redshifts", 1978) on a sample of such pairs have shown that some galaxy-quasar pairs have the same redshift and so are accepted as being at the same distance.

Harmonic Cloud Patterns on Jupiter

RayTomes — Wed, 20 Feb 2008 18:11:14 -0800

Regularly spaced clouds appear in Jupiter's belts, sometimes white spots and sometimes swirling waves. A polar projection of Jupiter, made by NASA from the 2000 flyby, allows accurate testing of the hypothesis that these waves form as predicted by the Harmonics Theory. It is found that expected strong harmonics 12, 24 and 72 are present.

The NASA/ESA Hubble Space Telescope, in collaboration with several other ground- and space-based telescopes, has captured a galaxy being ripped apart by a galaxy cluster's gravitational field and harsh environment. The finding sheds light on the mysterious process by which gas-rich spiral-shaped galaxies might evolve into gas-poor irregular- or elliptical-shaped galaxies over billions of years.

Time Dilation - An Experiment With Mu-Mesons

TIME DILATION: an experiment with mu-mesons

This classic film documents an experiment done in 1963 the results of which can only be explained when one accepts the consequence that moving clocks run slow. This phenomenon is known as time dilation. The timekeeping device is the mu-mesona, a subatomic particle with origins away from the Earth moving at relativistic speed. What follows here is an explanation of the experiment described in that film.

In case temperature increases, the coating will release the sweat accumulated, reproducing the human natural sweating process through evaporative cooling.

Order in Spontaneous Behavior

brembs — Wed, 22 Aug 2007 06:07:09 -0700

Brains are usually described as input/output systems: they transform sensory input into motor output. However, the motor output of brains (behavior) is notoriously variable, even under identical sensory conditions. The question of whether this behavioral variability merely reflects residual deviations due to extrinsic random noise in such otherwise deterministic systems or an intrinsic, adaptive indeterminacy trait is central for the basic understanding of brain function.
