Growth in the sea comes down to a struggle for iron

...reported the first series of iron experiments that indicated iron was indeed the missing ingredient. And he went further than that. Since growing plants absorb carbon dioxide, a powerful greenhouse gas, he suggested that natural increases in iron inputs to the oceans during the geologic past may have removed e...

UCLA Study Shows One-Third of Drug Ads in Medical Journals Do Not Contain References Supporting Medical Claims

... data-on-file, but more than half of the responses indicated that the information would not be provided due to company policy or because it was proprietary. "We found that almost one-third of the pharmaceutical ads offered no references at all to support medical claims. In addition, most of the data-on-file d...

Newly discovered virus linked to childhood lung disorders and Kawasaki disease

...es. The Yale investigators, termingthe novel virus indicated by their findings the New Haven coronavirus,then used probes specific for the virus to screen respiratory specimensfrom 895 symptomatic children under age 5 who had tested negative forother viral infections. They found 79 (9 percent) who were positiv...

Scientists decipher genome of fungus that can cause life-threatening infections

...prevent rejection of transplantedorgans. One study indicated that as many as 13 percent of AIDS patientssuffer a life-threatening cryptococcal infection at some point duringthe course of their HIV disease. The disease caused by the fungus,cryptococcosis, sometimes involves a fatal brain inflammation."In develo...

How an AIDS-Related Cancer Unleashes Inflammation

...g to Ganem, early studies of Kaposi's sarcoma (KS) indicated that the abnormal growth of infected cells required the overproduction of cytokines ?immune system proteins that trigger the cell's inflammatory response. A central question, he said, has been how does the Kaposi's sarcoma-associated herpesvirus that...

Exposure can occur from undercooked products or through cross-contamination during food preparation, when raw poultry is handled in the kitchen. The danger of infec...

Substance protects resilient staph bacteria

...A, but other research in Dr. Otto's laboratory has indicated that PGA production is greater when a biofilm is present. Further, Dr. Otto says all 74 strains of S. epidermidis that his group tested also produced PGA, as did six other genetically related Staphylococcus pathogens. "This could be very important to...

Computational Method Speeds Mapping of Cell Signaling Networks

...ignals. An increase in the amount of the molecules indicated spots where they were most active. Information about the simultaneous activities of several signaling molecules in thousands of individual cells was analyzed using a powerful computational method called Bayesian network modeling. Bayesian analysis u...

Solutions that reduce death of marine life reeled in by International Smart Gear Competition

...s' logbook data and studies of sea turtle behavior indicated sea turtles swim and become hooked in shallower waters than tuna, the target species of most longline commercial fishing. According to Duke University researchers, more than 200,000 loggerheads and 50,000 leatherbacks are accidentally caught annually...

Discovery may lead to better Candidiasis drug

... the suspect target was missing. Further research indicated that histatin binding to the target protein killed the fungal cells by preventing it from regulating its ions, the positive and negative charged molecules that move into, and out of, cells. Ions regulate electrostatic pressure between the cells' inte...

Different microarray systems more alike than previously thought

...latforms had proved inconsistent. Previous studies indicated that Affymetrix GeneChips, for example, the commercially available and most expensive of the three platforms tested, provided different results from other platforms. Affymetrix GeneChips provided highly reproducible, or consistent results, but for a...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...enerated each time the bull vocalized. The results indicated that elephant vibrations are unlikely to travel more than 2 miles in the soil, not 20 miles as previously estimated. Why the discrepancy? Geology may be one reason. Seismic waves move at different speeds in different soils. In Salinas, vibrations ra...
