Nanobacteria in clouds could spread disease, scientists claim

...se, and HIV is also slowly being recognised by the scientific community. "Experiments have shown that nanobacteria are excreted from the body in urine and their dispersal from the ground into the atmosphere and stratosphere appears to be inevitable," said Dr Sommer. The scientists argue that their occurrence ...

Alcohol consumption disrupts breastfeeding hormones

"Scientists studying cell migration have focused on the front of the cell and what drives it, while cell division researchers have concentrated on the furrow within the dividing cell," says Devreote...

Innovative coating could give medical implants a longer life

...the American Chemical Society, the world's largest scientific society. While the coating has not been tested in humans, it holds promise for use on a variety of medical implants including urinary catheters, cardiac stents, biosensors and dental implants and devices. The coating also could be used to prevent th...

Scientists use manufacturing methods to reconstruct mastodon

...astodon is important for what it can contribute to scientific understanding, Fisher said. Whereas most mastodon specimens are only about 20 percent complete, 70 to 80 percent of the Buesching mastodon's skeleton was found. "Having even a few specimens as complete as this one removes a lot of the guesswork that...

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

...y, added: "There are many quick fixes on offer 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 ma...
