Genome study of beneficial microbe may help boost plant health

...sion Service. The article in Nature Biotechnology presents the first complete genome sequence of a biological control agent for combating plant diseases. P. fluorescens Pf-5 was discovered two decades ago by Charles R. Howell, a plant pathologist with the ARS in Texas, who showed that the microbe suppressed...

Malaria killing a million a year

...2000, but an annual death toll of 1 million people presents challenges as the mosquito-borne parasitic disease makes a comeback, the first joint malaria report from the UN World Health Organization (WHO) and UN Children's Fund (UNICEF) says. The report on the disease that claims three times as many African c...

Discovering an ecosystem beneath a collapsed Antarctic ice shelf

...thin the Sea of Japan. The recent report, however, presents the first finding of the type in the Antarctic, where the near-freezing water temperatures and almost completely uncharted territory will likely provide a baseline for researchers to probe portions of the ocean floor that have been undisturbed for ne...

Stem cells bring fast direct improvement, without differentiation, in acute renal failure

...nd intensive care. Treating patients with ARF thus presents a major clinical dilemma, particularly when severe ARF occurs with multiple organ failure," Christof Westenfelder from the University of Utah explained. "Our laboratory has therefore been pursuing development of novel therapeutic interventions that a...

Genomics researchers discover protein deficit that causes drug toxicity

...is genetically variable response and the danger it presents over 20 years ago, no one had been able to explain the cellular mechanism behind it. ...

Breast tumors in mice eradicated using cancer vaccine

...t we encounter is that often by the time a patient presents with cancer, they've developed immune tolerance to the tumor antigen, particularly when the antigen is expressed at low levels on normal tissue as with Her2/Neu," explains Paterson. "So how is the body to mount a strong enough immune reaction?" In g...

Brain networks change according to cognitive task

...thin interconnected brain networks, said the study presents "the clearest and most convincing evidence to date" of the dynamics in effective connectivity. To better understand dynamic effective connectivity, Mesulam compares the brain networks to a network of highways connecting different parts of a city. Th...

Researchers find ways to turn manure into power

...ss into energy?" he said. The solid feedlot waste presents a different challenge than the liquid waste from hog or dairy operations, Sweeten said. Researchers are trying to determine what process and what mix of the product will create the most useable heat and, as a result, energy. For this study, composit...

New book expands biological classifications to account for 'alien' life

...ea would contain life found away from Earth. Ward presents his new model in a book called "Life As We Do Not Know It: The NASA Search for (and Synthesis of) Alien Life," published by Viking and being released Thursday. The new system is already necessary, he said, because "alien" life has been created in lab...

Grasshopper love songs give insight into sensory tuning

...the evolution of sensory circuitry. "Our approach presents a systematic way to uncover potential mismatches between the statistical properties of the natural environment and the coding strategy of sensory neurons. In turn, these discrepancies might improve our understanding of the evolutionary design of the ...

K-State professors discover enzyme responsible for creation of a beetle's hard shell

...e Proceedings of the National Academy of Sciences, presents the research results. The K-State researchers are Yasuyuki Arakane, research associate in biochemistry; Subbaratnam Muthukrishnan, professor of biochemistry; Richard Beeman, adjunct professor of entomology; Michael Kanost, professor and head of the d...

Many smokers fail to quit after cancer diagnosis

...ervices are available, but the diagnosis of cancer presents complex physical and emotional challenges to applying tools in the guidelines to cancer patients who smoke. For example, certain pharmacotherapies may be contraindicated or co-morbidities, such as depression and/or alcohol use, must be taken into acc...

A bug's life: Exceptional genomic stability yet rapid protein evolution in a carpenter ant mutualist

...reen's group from the Marine Biological Laboratory presents new data that support a fascinating model for genome evolution in bacteria that live inside insects. The scientists show that symbiotic bacteria have undergone exceptionally fast rates of protein evolution despite having precisely maintained their g...

Chernobyl: The true scale of the accident

...r targeting only high-risk groups is unpopular and presents political problems. Given significant reduction of radiation levels during past twenty years, governments need to revisit the classification of contaminated zones. Many areas previously considered to be at risk are in fact safe for habitation and cu...

Prostate cancer uses Wnt signaling proteins to promote growth of bone tumors

...hed in the Sept. 1 issue of Cancer Research, which presents results from U-M studies of Wnt proteins in human prostate cancer cell lines and in laboratory mice injected with prostate cancer cells. "Normal bone growth and remodeling depends on a controlled balance between production of new bone and resorption...

New study shows patients more willing to consider self-injectable HIV therapy than many physicians anticipate

Tsunami + 1 year: Reviving exhausted fisheries should trump replacing boats, gear, experts say

...ers, providing boats and gear to those that remain presents no risk to the sustainability of stocks or to the longer-term livelihoods of fishers." WorldFish warns that: 1. The catching power of new boats and fishing gear is likely to be higher than those they replaced; 2. When other livelihood options a...
