...independent assessment of how they are faring. As a result, concerns have circulated among prehistorians in France and throughout the world that the rescue operation itself was endangering the cave's delicate equilibrium, and further damaging the site. Last month French officials admitted to Time that the Fusarium solani fungus has on occasion spread from the floor to the paintings, and that separate fusarium strains have now been identified in the various arms of the 235-m cave complex. Time was allowed to visit the cave because its keepers feel they finally have the outbreak under control. But to keep...
...disappeared entirely. More than two-thirds of the 110 species of colorful harlequin frogs in Central and South America, two shown above, have also disappeared. Scientists believe that what killed many of the harlequins and what threatens a great many other amphibian species is a disease caused by the fungus Batrachochytrium dendrobatidis. Climate change seems to be making frogs more vulnerable to infection by the fungus...
...scientists studying climate change. Quick and polychromatic, the frogs spend their days near stream banks, where their constant motion and vibrant hues make it easy for researchers to count them. Previous studies have shown that it's not heat alone that kills harlequins but also a pathogen--the chytrid fungus--that attacks their skin. The chytrid is actually a cool-weather organism, doing best at temperatures from 63°F to 77°F. Paradoxically, an effect of global warming is to increase cloud cover in the tropical forests, lowering daytime temperatures and making the frogs more vulnerable to fungal assault...
...wouldn't be surprising if he, or someone in his lab, believed strongly enough in the work to be willing to cut corners. If that's true, the precipitating event could have come last January, when some of his stem-cell samples became contaminated, possibly by a fungus circulating in poorly shielded air vents...
...cell lines at all. In a nationally televised press conference the next day, Hwang denied the accusations, saying he would retest five remaining frozen stem-cell lines to prove his cloning techniques were authentic-at the same time acknowledging that the other six colonies had been contaminated by a fungus. "One thing is for sure," said Hwang. "Our team did produce customized stem cells, and we possess the core technology to produce them." Hwang went on to suggest that "somebody" at Roh's MizMedi Hospital had tampered with at least five of the stem-cell lines presented in the Science...
