W.M. Keck Foundation funds study of friendly microbes

...between microbes and humans will allow light to be shed on this previously mysterious interior world. Our objective is to understand how the human body functions as a carefully woven fabric of interacting species. Ultimately, such understanding promises to provide new ways of fortifying health and prevent...

Whole genome fine map of rice completed

...studying the differences among strains of rice and shed insight into mechanisms of hybrid advantages at a new level, according to BIG researchers. The efficiency and data quality of the fine maps of two strains of rice, Indica and Japonica, are better than the draft sequence published in 2002. The fine m...

Sea skate experiment sheds light on human cell transport

...y resemble cells in the human kidney, the findings shed light on how these organs cope with excess water. But Goldstein and Musch also believe the mechanisms that trigger this cellular "release valve" are universal. "We think that vesicle insertion, coupled with phosphorylation, is a broad mechanism for ...

Same mutation aided evolution in many fish species, Stanford study finds

...rick time and again to allow freshwater species to shed their burdensome body armor and transform into a lighter, spryer fish. This is among the first times scientists have shown that the same genetic change is responsible for an evolutionary adaptation in disparate populations. "Almost every time the st...

Scientists reveal molecular secrets of the malaria parasite

... in the mosquito vector.Researchers hope this will shed light on how the mosquito and parasiteinteract, and perhaps will lead to new ways of controlling the parasitein the vector. * Hall and scientists in Leiden identified evidence ofan unusual method of gene regulation (called post transcriptionalregulat...

Studies reveal methods viruses use to sidestep immune system

...up at UT Medical Branch in Galveston. The findings shed light on how HCV disrupts a separate immune pathway in infected liver cells, again by unleashing the NS3/4A protease to cleave another protein essential to triggering immune defenses. Again they found that protease inhibitors could reverse the effect...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...knowledge of the insect breathing pattern it could shed light on when pesticides should be used to control insects -- crucial for the agricultural industry." ...

The Shapes Of Life: NIGMS Project Yields More Than 1,000 Protein Structures

... 1,000 different structures. These structures will shed light on how proteins function in many life processes and could lead to targets for the development of new medicines. The PSI is a 10-year, approximately $600 million project funded largely by the National Institute of General Medical Sciences (NIGM...

Estrogen-like Component of Plastic Stimulates Growth of Certain Prostate Cancer Cells

...cer tumorimplants in laboratory animal models will shed additional light onwhether the synthetic pseudo-estrogen encourages tumor growth in wholeanimal systems.“We’ll know more about the ‘hormone sensitizing?ability of BPA inprostate cancer cells from studies on animals. It is also important tonote that o...

Scientists solve structure of key protein in innate immune response

...rtant in LPS transfer. Not only do these findings shed light on how cells recognize pathogens, they also may also lead to the development of drugs to help treat septic shock, an often fatal systemic bacterial infection that is triggered by LPS. "Pharmaceutical companies have tried to develop anti-septic...

World's largest rainforest drying experiment completes first phase

...the trees ran out of water in the soil, they would shed their leaves. In fact, this study shows that the reaction to drought is instead a decrease in the rate at which tree trunks grew in diameter. Many small trees, measuring 4 to 10 inches in diameter, simply stopped growing during the end of the dry sea...

Scientists find fossil proof of Egypt's ancient climate

...rn Egypt, lo those many years ago. They also could shed light on the possible role weather and climate played in the dispersal of humans "out of Africa" and into Europe and Asia. Periods of substantially increased rainfall compared to the present are known to have occurred in the Sahara throughout the las...

Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows

...extremely fast and accurate imaging technique have shed light on the tiny movements of molecular motors that shuttle material within living cells. The motors cooperate in a delicate choreography of steps, rather than engaging in the brute-force tug of war many scientists had imagined. "We discovered tha...

Cricket's finicky mating behavior boosts biodiversity

...of new species. The scientists say their findings shed light on the role of individual choices in the evolution of species and the growth of biodiversity. "Animals with nervous systems and brains have preferences and can make choices," says Tamra Mendelson, an evolutionary biologist at Lehigh. "Changes ...

Hirsute Or Hairless? Two Proteins May Spell The Difference

Wisconsin researchers identify sleep gene

...e which genes underlie this phenomenon in order to shed light on the mechanisms and functions of sleep," Tononi says. The Wisconsin study focuses on factors that control sleep duration as opposed to the timing of when sleep occurs, which is regulated by the circadian system, Tononi notes. "The key molecu...

Flocking together: Study shows how animal groups find their way

Key mechanism in genetic inheritance during cell division identified

...cts caused by certain Dam1 mutants. Their analysis shed new light on the structural nature of the kinetochore-microtubule interface, and may provide a biochemical explanation for the role of kinetochores in maintaining chromosome segregation during mitosis. "Our studies indicate that the Dam1 rings are f...
