Omega fatty acid balance can alter immunity and gene expression

For the past century, changes in the Western diet have altered the consumption of omega-6 fatty acids (w6, found in meat and vegetable oils) compared with omega-3 fatty acids (w3, found in flax and fish oil). Many studies seem to indicate this shift has brought about an increased risk of inflammat...

Interaction between gene variants may alter brain function in schizophrenia

A collaborative study led by investigators from Massachusetts General Hospital (MGH) is giving what may be the first look at how interactions between genes underlie a key symptom of schizophrenia, impaired working memory. Functional imaging studies reveal how a combination of common variants in t...

Turtles alter nesting dates due to temperature change says ISU researcher

AMES, Iowa -- Turtles nesting along the Mississippi River and other areas are altering their nesting dates in response to rising temperatures, says a researcher from Iowa State University. Fred Janzen, a professor in ecology, evolution and organismal biology, has studied turtle nesting habits a...

Social interactions can alter gene expression in the brain, and vice versa

Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize. This is not a new idea to neuroscience, but one th...

Earthworm activity can alter forests' carbon-carrying capabilities

New study examines how rearing environment can alter navigation

Many animals, including humans, frequently face the task of getting from one place to another. Although many navigational strategies exist, all vertebrate species readily use geometric cues; things such as walls and corners to determine direction within an enclosed space. Moreover, some species su...

A cherry on top: Tart cherries may alter heart/diabetes factors

Fish extinctions alter critical nutrients in water, study shows

Ecosystems are such intricate webs of connections that few studies have been able to explore exactly what happens when a species dies out. Now, a Cornell study using computer simulations has teased out how the disappearance of a freshwater fish can affect the availability of certain nutrients tha...

Global changes alter the timing of plant growth, scientists say

Any gardener knows--different plant species mature at different times. Scientists studying plant communities in natural habitats call this phenomenon "complementarity." It allows many species to co-exist because it reduces overlap in the time period when species compete for limited resources. Now, ...

Research suggests beta agonists may alter the immune system
