Selenium: an insidious and persistent toxin

..., "because the primary impact is on the egg, which receives the toxin from the mother's diet. When the eggs are hatched, the developing fish metabolize the selenium. Some fish are visibly deformed, but others grow into adult fish that appear healthy yet fail to reproduce. Because there is no apparent fish kil...

...ably more brackish water than the saline inflow it receives from the Mediterranean and there is a stratified, two-layer flow that has a strong affect on aquatic life and seabed sediments. The Marmara Sea Gateway (narrow straits of Dardanelles and Bosphorus, and deep intervening Marmara Sea) provides a set of ...

NIH grants infrastructure awards for human embryonic stem cell research

...l is uncommitted and remains uncommitted, until it receives a signal to develop into a specialized cell. Researchers hope that the study of hESC will lead to a better understanding of cell function, cell differentiation, and human development. BresaGen, Ltd. is an Australian biotechnology company committed t...

Filtering patient's blood before kidney transplant allows transplant from any donor

...live donor operation where the transplant patient receives a kidney from a live person (most commonly a friend or relative) is far preferable to transplanting an organ from a cadaver, Montgomery says. On average, the kidneys last twice as long, they work right away, total hospital costs are reduced and pat...

First primate archaeological dig uncovers new tool development links

...sa Panger, a GWU post-doctoral research fellow who receives support through NSFs Integrative Graduate education and Research Traineeship (IGERT) program, said the discovery could help archaeologists establish new dates for tool development. She and Christophe Boesch of the Max Planck Institute for Evolutiona...

Gene found that controls stomatal cell growth in plants

... "This tells us that the TMM protein probably receives signals that orient the position of asymmetric cell division," Sack said. "The TMM protein is found in a set of stem cells and their progeny. It apparently controls which cells divide dur...

Communities dealing with hazardous waste need independent adviser, UCLA engineering professor says

...ser's "charter would be to make sure the community receives unbiased information," he said. Cohen and McCarty made several recommendations specific to the Del Amo site. One of their recommendations was that monitoring for contaminants should be done whenever there is any deep excavation in the area. "The EPA ...

Findings aid understanding of neurodegenerative diseases

...roper shape. In this delicate process, the protein receives its folding instructions from its amino acid sequence and is assisted by a class of proteins known as heat shock proteins or molecular chaperones that function to prevent misfolding, or, in the case of already misfolded proteins, to detect them and p...

Database lets researchers worldwide access genome of malarial parasite

...://PlasmoDB.org -- went live in June 2000 and now receives thousands of queries a day from more than 100 countries. With release of the complete genome sequence, the Penn team expects to see a further rise in activity. The database will be updated constantly as Plasmodium sequencing and annotation proceed....

OSU genetics expert wins award for lifetime achievement

De la Chapelle's keynote address will be, "Inherited Diseases: Challenges, Victories and Disappointments." "I am really quite honored, and very surprised,...

Three inferior prefrontal regions of the brain found receptive to somatosensory stimuli

...ain plays an important role in emotional behavior, receives direct inputs from the dorsomedial thalamus, temporal cortex, ventral tegmental area, olfactory system, and the amygdala (illustration). Its outputs go to several brain regions, including the cingulate cortex, hippocampal formation, temporal cortex,...

How crayfish do the locomotion

...y connect to. As the swimmerets beat, each module receives a stream of nerve impulses from the modules behind and in front of it. Signals from behind indicate a power stroke; those from the front represent a recovery stroke. Mulloney's team has found that those different messages converge on the same target ...

Without water, the body will shut down its need to ingest food

...ors (a receptor in the central nervous system that receives stimulus from the blood) or other detectors of body fluid status in the brain, circulation, or gut may be involved. In the rat, various stimuli known to cause thirst and antidiuresis also inhibit feeding, including injection of hypertonic solutions ...

Saving energy for sex

... identity of the oocyte cell surface molecule that receives and transmits the MSP signal to the intracellular MAPK machinery has, until now, remained a mystery. As published in the January 15 issue of Genes & Development, Dr. Greenstein and colleagues report that MSP binding to the VAB-1 receptor culminates i...

Too much oxygen on the cell biology bench? New study suggests so

...llular biology research, which receives billions of dollars of funding nationally, said Ohio State scientist Chandan Sen. He is the lead author of a study which suggests that cells act differently depending on how much oxygen they...

Crop producers go high-tech with GPS technology

Global positioning systems (GPS) and advances in computer software allow for precise identification of soil sample positions in the field and improved soil-test mapping. Variable...

UCSF study suggests novel factor could contribute to adult obesity

...ack a brain cell receptor known as 5-HT(2c), which receives signals from the brain chemical serotonin; an effect, though less dramatic, was also seen in normal mice. Traditionally, scientists have surmised that the increase in weight gain seen in middle-aged mammals, including mice and people, was due in part...

First molecule discovered that directs nerve cells to connect with each other

... cells form a close connection, and SYG-1 probably receives a signal to form a synapse from the animal's egg-laying tissue, the scientists report. Discovery of matchmaker proteins in humans may help treat disorders such as chronic epilepsy and chronic pain in which synapse formation goes awry and neurons form...
