Divergent life history shapes gene expression in brains of salmon

...places to mature in oceans versus those who do not leave the freshwater environment to mature. The researchers, at Harvard University, the University of Massachusetts and the US Geological Survey, report the finding in the current issue of Proceedings of the Royal Society B. They compared female salmon, m...

Looks matter to female barn swallows

...es in the population, the female is more likely to leave him and then secretly copulate with another male, according to a Cornell University study featured on the cover of the journal Science (Sept. 30, 2005). "The bad news for male swallows is the mating game is never over," said lead author Rebecca Safr...

Carnegie Mellon University research reveals how cells process large genes

...also indicates that most recursive splicing events leave no clues in the final mRNA. This is why they have not been detected before now." These previously undetected events could have profound implications for predicting what constitutes a gene and for studying gene expression, mutation and evolution, ac...

Hopkins scientists uncover 'tags' that force proteins to cell surface

...ikano uncovered 65 that forced a normal protein to leave the cell's protein-building factory and go to the cell surface. By searching sequences of known human proteins, the researchers then identified those that use variations of the most potent tag they'd found, dubbed SWTY, shorthand for the four buildin...

Identical twins may have more differences than meet the eye

...tart to look and act less alike. The changes could leave one twin susceptible to diseases like cancer, while the other twin remains healthy. Researchers report in this week's Proceedings of the National Academy of Sciences that these differences may stem from changes in the epigenome. The epigenome refers...

Computer modeling reveals hidden conversations within cells

...of the pathological functions of the proteins, but leave the healthy functions intact. For example, many current cancer drugs dramatically reduce immune function. Computer modeling should make it possible to design anti-cancer drugs that do not weaken patients' immune systems." The computer model compri...

Scientists find evidence of catastrophic sand avalanches, sea level changes in Gulf of Mexico

Study charts origins of fear

...e brain receives a shock. Over time, the receptors leave their imprint on brain cells. By delivering shocks to mice, the researchers activated the NMDA receptors and traced a subunit of the molecule - a protein called NR2B - long believed to be associated with fear memory in the hippocampus and the amygd...

Water management in cells

... of all activated. These ensure that chloride ions leave the cell. Further research revealed that the efflux of organics only starts one or two minutes later. This efflux only takes place if there is a large difference between the intracellular and extracellular salt concentrations. From this the researche...

New NIAID grants strengthen national biodefense and emerging infectious diseases research network

Each institution also leads an RCE consortium made up of universities and other research institutions within its geographic region. The network con...

Elusive salamanders have role in developing new sampling models

Techniques available to detect soil that inhibits destructive soybean pest

...f eggs while they mature, hatch into juveniles and leave the cyst to further attack the plant roots. Swollen females can be seen with the naked eye, but worm-like juveniles and males can best be seen with a microscope. As nematodes steal nutrients from the roots, the plants are weakened and don't grow wel...

Newly recognized gene mutation may reduce seeds, resurrect plants

If researchers learn how to control plant embryo abortion, they may be able to increase yield by helping plants shed fewer seeds, grains or fruits, especially under drought conditions and in other stressful envi...

Defective Gene Linked to Two Inherited Immune Deficiencies

Dendritic cells offer new therapeutic target for drugs to treat MS and other autoimmune disease

"But our studies show that though many dendritic cells were destroyed, some still remained," he said. Their tests also revealed that mice infected with a potent bacterium survived after treatment...

Mouse genome much more complex than expected

Each mRNA contains the blueprint for precisely one specific protein ?this at least has been the traditional doctrine. Three years ago the DNA of the mouse was completely sequenced...
