NSF funding to advance research on interplay between biology and society

...biology on society, and vice versa. Topics to be studied include widely disseminating the letters and other correspondence of Charles Darwin; ways to foster scientific collaboration with Native American communities on issues of sustainability; how populations in Brazil have used scientific information to a...

The kapok connection -- Study explains rainforest similarities

...come probable over 10 to 15 million years." Dick studied the rainforest form of Ceiba pentandra, a species of kapok that grows taller than a 16-story building, its head poking above the forest canopy. Its flowers produce more than 50 gallons of nectar per tree in a season, attracting bats that travel as ...

Fruit bats are not 'blind as a bat'

Marine phytoplankton changes form to protect itself from different predators

...s that had not been attacked. The scientists then studied how the different chemical signals affected the percentage of Phaeocystis living in colonies or as solitary cells. Finally, they examined whether this response affected how much the predators ate to determine if the change conferred a survival advan...

Microbes at work cleaning up the environment

...anoparticulate zinc sulfide spheroids. They also studied whether various amino acids induce rapid aggregation in metal-sulfide nanoparticles. The answer was yes in both cases. This demonstrates an extracellular biomineralization mechanism that is unexpected because it involves the bacteria excreting p...

Exploring the dark matter of the genome

...e functions. Karpen notes that one intensively studied and puzzling problem in chromosome biology will benefit enormously from the new findings: epigenetics -- the inheritance of traits and genetic information as controlled by proteins associated with the chromosomes, rather than by DNA sequence. Startin...

St. Jude study yields secrets of chromosome movement

...s the reports senior author. The St. Jude team studied combinations of molecules in yeast called the RITS and RDRC complexes, which together with an enzyme called Clr4 (Suv39 in humans), establish and maintain centromeric heterochromatin in the yeast cell during a carefully choreographed series of steps....

Cytokine resistance contributes to pathology of type 2 diabetes

...ansduction pathways, the Jak-STAT pathway, is well studied and well understood. The second, called the insulin receptor substrate 2 / phosphatidylinositol-3 kinase (IRS-2/PI3K) pathway, was more of a mystery, and of greater interest to Freund and his colleagues. What drew them to this pathway was its poten...

Banding together: RAS signaling of circadian output

... The fungus Neurospora crassa is one of the best studied laboratory systems for circadian rhythms. However, over the past 50 years, almost all of the work done on Neurospora has used laboratory strains carrying the band mutation, because it enables researchers to visualize the fungus' daily circadian growt...

University of Washington researchers play leading role in major study of human genome function

...nd the world. Even though the ENCODE consortium studied only 1 percent of the human genome, Stamatoyannopoulos believes their research will be useful for understanding the entire genome. The progress of the past four years has been breathtaking, as we have moved from being able to analyze only a few th...

The wider view from a detailed focus

...y copied in the cell, revealed the location and studied evolution of elements that control gene activity, and defined the relationship between DNA-associated proteins and gene activity and DNA replication. The complex tapestry of interwoven elements revealed today suggests that "our perspective ...

Food safety begins as vegetables grow

Beyond agriculture, the finding may also have key implications for understanding the dynamics of all social animals, including man. Pierces recently reported his research in an article appearing in the be...

Identification of genetic risk factor for coeliac disease promises improved treatment

...rols (i.e without coeliac disease). The consortium studied over four thousand individuals with and without coeliac disease, amongst British, Irish and Dutch populations. What they found is that healthy individuals more often have a protective DNA sequence in the interleukin-2 and interleukin-21 gene regi...

Hormone that signals fullness also curbs fast food consumption and tendency to binge eat

...s, the food intake effect of hormones in humans is studied only acutely, using a single meal test. More natural weight control? Unlike many diet pills, which typically block individual brain chemicals, hormone-based therapies such as pramlintide work by enhancing existing physiological pathways involv...

QUT microgravity tower attracts global scientific community

... scientists insights into phenomena not able to be studied in normal gravity since the effects of buoyancy, sedimentation and other convective disturbances are not present in gravity. For example, it has been demonstrated that the formation of certain silica nanomaterials is greatly enhanced when it occu...

2007 Image of the Year: Molecular imaging relates human brain chemistry to aggressive behavior

...ed that for more than two decades, scientists have studied MAO in relation to aggressive and violent behavior. Joanna S. Fowler, an SNM member, member of the National Academy of Sciences and a senior chemist at Brookhaven, developed a way to tag the MAO A enzyme and study its activity in the brain. The healt...

A new plant-bacterial symbiotic mechanism promising for crop applications

...oils in nitrogen. However, the symbiotic processes studied predominantly concern the leguminous plants of temperate zones, very little those of the tropics. The team from the IRDs Laboratoire des Symbioses Tropicales et Mditerranennes and its partners (1), taking as model a symbiosis between a tropical aqua...

The insect vector always bites twice

...2003 (1), scientists from IRD research unit UR 024 studied this still little known response with the aim of identifying in the arthropod vector saliva the immunogenic proteins responsible. They called on immunological techniques to evaluate qualitatively and quantitatively, in the serum sampled from human po...

What's going on in the body? Advanced time-of-flight PET takes a superior 'look'

...Pennsylvania in Philadelphia. "Previously, we have studied TOF/PET with computer simulations and controlled experiments to approximate the behavior within the human body, showing that we can get very good image quality with shorter scanning times," she said. "We have now moved our investigation to clinical s...
