Dinosaurs seem bigger than life – big bones, big mysteries. So it's a delicious irony that the next big answers about dinosaurs may come from small – very small – remains.

An experimental tuberculosis drug may be effective against not only multi drug-resistant forms of the disease but could also be the first compound to treat the latent stage of infection as well. Researchers report their results today at the 2006 ASM Biodefense Research Meeting.

Anthrax spores may survive traditional drinking water disinfection methods and can attach themselves to the inside surface of water pipes, suggesting water treatment facilities should be prepared to employ alternate disinfection methods in the unlikely event of the release of anthrax in the water supply. Researchers report their findings today at the 2006 ASM Biodefense Research Meeting.

Princeton biologist reports at AAAS on partnership with St. Louis Zoo to empower Kenyan communities in endangered Grevy's zebra conservation

There is growing consensus among scientists, regulators, politicians, industry and the public that we need to know more about the possible harmful or adverse effects of nanoparticles on human health.

The race is on to buy up inexpensive land along coastlines for vacation homes and tourist hotels. But increased development can mean more nutrient rich runoff that threatens the very coral reefs attracting tourists in the first place. David Kline at the Smithsonian Tropical Research Institute and colleagues find that bacteria on coral reefs grow out of control as the level of simple sugars in seawater increases.

Researchers at Children's Hospital of Pittsburgh have found that increased levels of certain proteins in the blood or spinal fluid may signal brain injury in infants with vomiting, fussiness and several other common symptoms.

As thousands of pink-footed geese (Anser brachyrhynchus) prepare for their spring migration north to breeding grounds in the Arctic, ecologists are warning that the escalating conflict between farmers and the geese is threatening the birds' survival. Writing in the new issue of the British Ecological Society's Journal of Applied Ecology, Professor Marcel Klaassen of the Netherlands Institute of Ecology says that international action is urgently required.

UC Riverside researchers have released a new variety of asparagus that offers a higher yield than previous varieties of the vegetable and boasts an excellent spear quality, marked by a high percentage of marketable spears. Higher yield of marketable spears reduces the impact of high land and labor costs, thereby making the asparagus more profitable without raising consumer prices.
