WHO Warns Of Increased Risk Of Vector-borne Diseases In Tsunami-affected Areas

...machines and spray tanks (as well as the hiring of vehicles for spraying activities). WHO also assists in the clean-up of debris in which water collects, to prevent the formation of dengue breeding sites. In India, a number of anti-vector measures are being implemented, including the strengthening of vector ...

Scientists journey to southern Africa to unravel the secret world of elephant communication

.... "This could potentially be used to track poacher vehicles as well." Eventually, O'Connell-Rodwell hopes to broaden her research to include other large animals that produce low-frequency vocalizations, such as rhinos, lions and giraffes. "Caitlin and others have already established that small creatures use ...

Edible bivalves as a source of human pathogens: signals between vibrios and the bivalve host.

Clams, mussels and oysters are important vehicles for the transmission of enteric diseases when consumed raw or undercooked. Vibrio species, including human pathogens, are particularly abundant in bivalve tissues, where they can persist even after cleaning procedures, thus representing a potential r...

'Sinkers' provide missing piece in deep-sea puzzle

...rs of Monterey Bay using MBARI's remotely operated vehicles (ROVs). After seeing how common sinkers were, Robison wondered if they might be delivering significant amounts of food (in the form of organic carbon) to the deep sea. As he explains, "When it became apparent that sinkers might be important carbon so...

HIV inserts into human genome using a DNA-associated protein

...ld of gene therapy. Controlling where gene-therapy vehicles insert in the human genome could help make the delivery of new therapeutic sequences safer. The new findings about LEDGF suggest that engineered tethering interactions might some day allow control over integration site selection during gene therapy. ...

Engineered Stem Cells Show Promise For Sneaking Drugs Into The Brain

...shows that stem cells can be used as drug delivery vehicles in the brain," says Svendsen, a professor of anatomy whose laboratory is at the UW-Madison Waisman Center. The new Wisconsin study, whose lead author is Soshana Behrstock, depended on formative brain cells that were coaxed from blank-slate stem cell...

USC, Rice to develop bacteria-powered fuel cells

... Force has long been interested in micro-scale air vehicles ?some as small as insects ?but it has been stymied by the lack of a suitable, compact power source. With $4.4 million from the Department of Defense's Multidisciplinary University Research Initiative, or MURI, the USC and Rice research team hopes to ...

The molecular mechanism that underlies this coordination is reported by lead researcher Nava Segev, UIC professor of biological sciences, in the November i...

Edge density key to controlling gypsy moth spread

...External colonies occur when moths hitch a ride on vehicles or other items relocated by people. Without an Allee effect, these colonies would establish, but because gypsy moths exhibit an Allee effect, the low populations are insufficient for establishment of permanent populations. This is also true at th...
