Insects implicated in the evolution of new human infectious diseases
...s luminescens infection are left luminous. Genome studies
have found close similarities between the plague-causing bacterium, Yersinia pestis, and its ancestor, Yersinia psuedotuberculosis, which has been shown to be capable of causing disease insects, at least in the laboratory. Evidence suggests that the ...
Clues to the puzzle of 'talking' root cells
...the Short-Root protein in living root cells. These studies
indicated that in the cells from which the protein moves, it exists in the cytoplasm not associated with any molecular complex. However, the tracer did not reveal that the protein was moving from one cell to another. The researchers also fou...

have documented tool use among chimps in eastern Africa and other regions, authors Crickette Sanz of Max Planck Institute for Evolutionary Anthropology, WCS researcher David Morgan of Cambridge University, and Steve Gulick of Wildland Security say th...
Study: Inadequate physical activity worsens as teenagers become adults
...eath for Americans," Gordon-Larsen said. "Previous studies
at UNC and elsewhere have shown that all major racial and ethnic groups and both sexes get too little physical activity, and black and Hispanic girls face the greatest risk of being significantly overweight or obese and inactive." In the new re...

Paratek Pharmaceuticals presents multiple sclerosis data at Society for Neuroscience annual meeting
...maceuticals, Inc. announced results of preclinical studies
demonstrating that a new class of compounds, orally available non-antibacterial tetracyclines, has shown promising activity in a preclinical animal model of multiple sclerosis (MS). Affecting approximately two million people worldwide, MS is a chron...
Evidence that learning is consolidated during sleep
...id eye movement (NREM) sleep. Evidence from animal studies
of learning and sleep indicated that spatial memories seem to be replayed in the hippocampus during the deep "slow wave sleep" (SWS) during the NREM sleep stage. Peigneux and his colleagues explored the memory consolidation process by asking voluntee...
Trojan-horse therapy blocks buildup of Alzheimer's plaque
... penetrate the cell membrane to enter the cell. In studies
of the molecules' effects on amyloid growth in cultures of neurons, the researchers confirmed that the Trojan horse molecules substantially reduced the toxicity of the amyloid by inhibiting growth of the shorter, more toxic chains of the amyloid plaq...
ASU gets grant to develop high speed DNA sequence reader

to identify genes that contribute to cancer, diabetes and other common diseases. The ASU team is utilizing part of the machinery of a human cell, which can read out the entire genome and make an exact complimentary copy of human DNA in about 24 hour...
Diabetic damage to eyes, heart, nerves, kidneys may be explained by controversial theory
...ypoxia. Williamson and his coauthors used in vitro studies
of rat retinas to show that both of these conditions decrease the ratio of NAD to NADH in different ways. Hyperglycemia does it by increasing the rate of transformation of NAD to NADH. Hypoxia makes it difficult for cells to turn NADH back to NAD. ...

indicate that PKC may also be overactive in the brains of patients with schizophrenia. Antipsychotics, which are used to treat bipolar disorder as well as schizophrenia, block receptors in the brain that activate PKC....
Research uncovers role of Apolipoprotein E in Alzheimer's disease
