Other collaborators include: the Department of Primary Industries ...

The insect vector always bites twice

The reality of the threat from vector-borne diseases has been recognized and the problem is prompting research scientists to take a strong interest. Most of these infections, classified as emerging or re-emerging diseases, are linked to ecosystem changes, climatic variations ...

Researchers examine carbon capture and storage to combat global warming

...asphyxiation and groundwater contamination. The threat of asphyxiation-or suffocation due to carbon dioxide displacing oxygen-is very low, the researchers said, because of the unlikelihood of a rapid leakage, which would have to occur to cause a problem. Drinking water contamination, Benson said, is t...

Warning from Asian bees

...s themselves could pose the beginning of a serious threat to Australian honey bee populations. Asian bees are known to have found their way into Australian ports at least half a dozen times in the last decade. This time it’s a Javanese strain of the bee and because the latest incursion had lain undiscov...

Potato wart eyed as risk to potato production

...t List" of plant pathogens deemed to pose a severe threat to plant health or to plant products. Although direct losses from potato wart may be insignificant when first detected, indirect economic losses resulting from zero-tolerance regulations for potato wart can be devastating to growers. Indirect eco...

Researchers demonstrate way to control tree height

... trees such as this are unlikely to be any kind of threat to spread, because they would compete very poorly with normal or wild trees. In virtually all tree species, low height is a disadvantage as trees compete for sunshine. Another possible value, from that perspective, is that this trait might be used to...

How plague-causing bacteria disarm host defense

... Ages. "This bacterial species could still be a threat today," said Navarro, adding that scientists had isolated an antibiotic-resistant strain of this species. In addition Y. pseudotuberculosis and Y. enterocolitica are big words for nasty, little bugs that cause what's commonly known as food poisoning...

Want to save polar bears? Follow the ice

...e near these fast swimming marine mammals. Another threat to the bears is the unpredictability of the melting of the sea ice away from the coast regions that bears shift to in the warmest parts of the year. Bears that make it to shore may be there for increasingly longer periods of time without food as the...

Amphibians in losing race with environmental change

...cur within some amphibian populations when a novel threat arises, other threats may be too intense and too new for amphibians to cope with them," the researchers wrote in their report. "Behaviors and ecological attributes that have probably persisted, and were probably beneficial, for millions of years . . ...

Hives ferment a yeasty brew, attract beetle pest

... hive beetles are common in Africa and pose little threat to African honeybee hives, it appears that domesticated European honeybees have a much harder time containing the beetles in their hives. European honeybees were bred to be docile and easy to work with, while African honeybees are noted for aggressio...

Fauci, M.D. “The new NIAID Centers of Excellence for Influenza Research and Surveillance will help expand the federal government’s e...

Corals that can fight global warming may one day help fragile reefs

..."Some corals show unusual resilience to the double threat [of pathogens and warming seas], and we should look to these hardy corals for clues that might enhance others," said Harvell. "Other corals are more sensitive and will not survive the continued warming trend." Yet there seems to be future promise f...

Veterinary scientists explore poultry virus as cancer killer
