Climate change and permafrost thaw alter greenhouse gas emissions in northern wetlands

... change. What this means for ecosystems and humans residing in the North remains of the most pressing issues in the climate change arena. Working closely with researchers from Southern Illinois University, Villanova University and the National Renewable Energy Laboratory, Turetsky, assistant professor of cr...

EDITOR's PICK A friendly foe: Bacteria residing in the gut boost immune response to tumors One potent, immune-based treatment for cancer is total body irradiation (TBI). This approach first depletes the body of the population of immune cells known as lymphocytes and then involves the adoptive ...

Economic impact of hunger affects all Americans

...idual basis, it means that on average, each person residing in the U.S. pays $300 annually for the hunger bill. Distributed on a household basis, it means that the annual cost is closer to $800 each year. And calculated on a lifetime basis, each individuals bill for hunger in the nation is nearly $22,000. ...

Research suggests a significant circadian rhythm in swim performance lasting 2-4 minutes

...adian rhythms originate from the tiny hypothalamus residing in the back of the brain. The hypothalamus, working with the endocrine system, drives many of our behavioral and physiological rhythms. Researchers have speculated that there may be a circadian rhythm inherent in athletic performance and point to ...

Together, biological membranes prevail

...oteins called SNAREs. Complementary SNARE proteins residing within the incoming and target membranes form a bundle, and bring the two membranes close enough for the merging to occur. The fusion is thought to proceed through highly fleeting intermediates that are very difficult to study when many membrane fusi...

Gene knockouts reveal FoxOs' vital functions in cancer defense, health of stem cells

... and regulated differently the same types of cells residing in different types of tissues." This is important knowledge, he said, for further research and for testing novel drugs in the right types of cancers. DePinho and Gilliland emphasized the importance of the collaboration between Brigham and Women's a...

Researchers determine why wolves not dispersing as fast as expected in Yellowstone

...from the original 31, with about 150 of them still residing in the park boundaries. However, wolves have been known to disperse at a rate of 100 km a year, but the Yellowstone wolves have only spread at one-tenth that rate. The slow dispersal rate had stumped researchers across North America until a team of...

No guts, no worries

...es--to obtain a profile of the microbial community residing in a particular environment. This is the first instance of such a symbiotic relationship being analyzed by using a metagenomic shotgun sequencing approach, heralding a renaissance in symbiosis research. In this experiment, Woyke donned scuba equipm...

Spineless tales provide strong backbone to human brain research

In a paper that appeared online July 25 ahead of regular publication in the journal Integrative and Comparative Biology, Tublitz and ...

Johns Hopkins researchers find link between cell's energy use and genome health

...copes revealed that this second enzyme, Asc2p, was residing - unexpectedly -- in the part of the cell housing its genetic material - its chromosomes - rather than in the part of the cell - the mitochondria -- that harvests energy from sugar. But why would an enzyme involved in generating energy live in t...

"Microbes are too small to be seen with the naked eye," said Carl Woese, professor of microbiology at the University of Illinois at Urbana-Champaign, whose pioneering contribution of phylogenetic taxonomy of 16S riboso...

Oregon researchers show how resident bacteria shape gut development

...ity of Oregon researchers have shown that bacteria residing in the intestine shape gut development by means of several distinct signaling mechanisms. This research is now available in the online version of the journal Developmental Biology and will be published in the journal's August print edition. The re...

The long and the short of it: Expanding small RNA biology in mammals

...tudies independently identifying unique small RNAs residing in the mouse germline. The newly identified piRNAs are bigger in size (26-31 nucleotides long) than most previously described small RNAs in mammals, and are shown to be associated with the piwi subfamily of the Argonaute protein family. They are larg...

Surprising symbiosis: Glassy-winged sharpshooter eats with friends

...hat the two resident bacteria are close neighbors, residing next door within host tissues and feeding each other chemical precursors needed to make nutrients. In the future, Eisen says, the bacteria will likely evolve into organelles of the insect, losing their distinction as bacteria altogether. Looking ahe...

Research provides clues to obesity's cause and hints of new approach for curbing appetite

...called the hypothalamus, leptin binds to receptors residing on the surface of neurons, setting off signals that tell the brain to stop eating and the body to expend energy by burning calories. While obese people produce much higher levels of leptin than thin and normal-weight individuals, they are somehow res...

Contaminants linked to sturgeon decline in Columbia river

"Fish residing in the reservoir behind the oldest dam had the highest contaminant loads," Feist added, "and exhibited reduced growth and reproductive fitness when compared to fish sampled in other locations. These data suggest that some contaminants may be accumula...
