Sandia researchers take new approach to studying how cells respond to pathogens

...ion (MCR) is used to image the tagged proteins and provide quantitative measurements on multiple proteins simultaneously. The goal is to analyze as many as 10 to 40 proteins and cellular stains at a time in three dimensions. The end results of the imaging and protein analysis are large amounts of data tha...

2 brains -- 1 thought

...rks that exhibit a given dynamics. With this, they provide researchers with a tool which can be used to investigate the correlation between structure and function of a neuronal network. A common approach in scientific research is to investigate the structure of a system in order to then draw conclusions a...

Brain's reward circuit activity ebbs and flows with a woman's hormonal cycle

...uencing reward-evoked brain activity in humans may provide insights into menstrual-related mood disorders, women's higher rates of mood and anxiety disorders, and their later onset and less severe course in schizophrenia," said Karen Berman, M.D., chief of the NIMH Section on Integrative Neuroimaging. "The s...

...ll," he says. "So this is a total of 10 lakes that provide three separate instances -- one in Brazil, one in Ecuador and one in Peru, where there is evidence of long, continuous occupation of more than 5,000 years that did not spread to the adjacent, 8 to 10 kilometer distant lakes." The findings are pub...

Red flag for repetitive stress injuries identified for first time in humans

...ould also indicate another type of injury, they do provide a red flag where before there was none," said Barr, associate professor of physical therapy at Temple's College of Health Professions. Currently, healthcare providers can diagnose repetitive motion injuries (RMI) based only on physical examination...

Male-killing bacteria makes female butterflies more promiscuous

...land and South-East Asian populations. The islands provide an ideal location because every island is differently affected by the male-killling bacteria so that each has a different ratio of males to females. The researchers assessed the natural sex ratio in 20 populations and combined this data with femal...

Mutation improves memory, may lead to memory-enhancing pill

...d. "If such a pill could be generated, it might provide a new method for treating people with memory-related diseases such as Alzheimer's," said Mauro Costa-Mattioli, a senior postdoctoral fellow in Sonenberg’s laboratory. "While a drug that worked in this way wouldn't cure the disease itself, it might re...

Mine runoff continues to provide clues to microbial diversification

...obial biofilm communities found in the mine runoff provide perfect research subjects because they have fewer organisms than most communities found in nature. The reason, Hettich noted, is that these environmental conditions ?a pH of 0.8 -- are too extreme for most organisms to survive. A pH level of 7 is con...

Cambodian vulture nests offer hope for species
