Fungus knocks a frog down but not out, raising questions about amphibian declines

...ption until now has been that when a population is hit by this pathogen it is wiped out. It doesn't appear to be that simple. "In Central America and Eastern Australia, the same pattern has occurred the frog populations have been healthy and all of a sudden there is a crash and some species are...

Low dose radiation evades cancer cells' protective 'radar'

Amphibians in dramatic decline; Up to 122 extinct since 1980

...hly infectious disease called chytridiomycosis has hit amphibians especially hard. New research is showing that in some regions, outbreaks of the disease may be linked to drought years, which scientists are increasingly attributing to the effects of climate change. But in most parts of the world inc...

Multi-species herbivore outbreak follows El Nio drought in Panama

... global temperatures rise. And because herbivores hit some tree species harder than others, repeated herbivore outbreaks could change the species composition of the forest. In a recent volume of the Journal of Tropical Ecology, ecologists in Borneo reported a similar outbreak in response to the ENSO ev...

Hurricane damage creates pecan shortage

...y reduced pecan crop. Alabama, which took a direct hit from Hurricane Ivan, lost 80 percent of its total crop. Damage to the pecan trees include pecans blown prematurely from the limbs, twisted limbs and limb breakage, as well as severe tree leaning and loss of entire trees. Approximately 15-20 percent o...

The connection between the pelvis and spine is stronger and larger relative to body size in humans than in their ancestors, providing more stability and shock absorption during running. Human buttocks "are huge," says Bramble. "...

As if this discovery weren't enough to earn the dwarf mistletoe a place of honour by the front door, Dr. Ross says her probing has revealed another floral first that's "really going to shake things up" in the world of plant reprodu...

Laser scalpel opens way for nerve regeneration studies in worms

The researchers also noticed an intriguing and potentially important result: The worms that had been operated on showed evidence that the nerves had regrown and also regained the ability to move the muscle served by the neuron. This ...

Science's Breakthrough of the Year: Salty, acidic soup could have supported life on Mars

.... Genes in a Drop of Water: In 2004, researchers hit on a new way to identify life forms too small and remote to see with the naked eye. They collected water from environments as different as the Sargasso Sea and the depths of an abandoned mine and sequenced the genes floating in it. This work has turn...

Violent ocean motion no magic potion for reefs

Hurricane churning also completely covered many reefs with sediment, and dusted the rest. Just before the hurricanes hit, the team had also begun to see patches of Lyng...

Research turning up the heat on fowl bacteria

...ation went haywire, Dr. Thompson says. "So we have hit on something that affects a large number of different processes in the cells. The genome of Campylobacter had been sequenced so CJ1461 was known, but there was only an educated guess as to what it did. What it appears to be is a DNA methylase, whi...

New evidence indicates biggest extinction wasn't caused by asteroid or comet

They contend that if there was a comet or asteroid impact, it was a minor element of the Permian extinction...

DNA molecules used to assemble nanoparticles

The self-assembled dendrimer clusters were shown to be well formed and functional. "This is the proof-of-concept experiment," Choi said. But now that the assembly system...

Population of rare gorillas may be increasing in war-torn Congo
