Scientists use manufacturing methods to reconstruct mastodon

...e full-scale replicas of the bones they lack. "In cases where there are paired bones in the body—left and right—but we found only one, we can generate the missing bone by making a digital model of the one we have, reflecting it on the computer and then producing a physical prototype of the reflected model...

(http://www.who.int/lep/stat2002/global02.htm) "Leprosy is still very real and devastating to patients who aren't treated appropriately. The better we can understand this pathogen's genome and the subtle differences among its ...

Tsunami-damaged coral reefs should be left to recover naturally, say scientists

...ffer but scientific evidence suggests that in most cases these would not be a good use of scarce resources and could actually harm surviving reefs. We need to find a long-term, sustainable solution for restoration. "We're advocating a cleaning up of the debris in the majority of cases, so as to allow natur...

Life detection instrument passes key test on road to Mars

...bers carried the complete analyzers in three large cases to Chile by plane - in itself a test of the ruggedness of the equipment - and trucked them to the barren Yunguy field station, essentially a ramshackle building at a deserted crossroads. With a noisy Honda generator providing power, they set up their...

In cases where the normal RNA shape and the DNA constraint cannot co-exist simultaneously, the balance between competing RNA and DNA structures is controlled by the concentration of magnesium ions, Silverman said.

(Half of the Earth is under more than 3,000 meters of water. The seas' deepest trenches drop to 12,000 meters.) While results from these samp...

Malaria mechanism revealed

... Malaria causes approximately 400 million clinical cases and 2 million deaths annually, with more than 80% of deaths occurring among children. The disease is caused by mosquito-borne parasites of the genus Plasmodium (primarily Plasmodium falciparum). Following the initial stages of infection, merozoite-st...
