She believes these could have many applications outside of the PLANTS project. "We were speculating, for example, that they might have an application in hostile environments, like gro...

"We're doing more extensive work on those figures in ourlab at Bushland. We want to determine how many eggs they lay, the life...

Mosquito spray increases toxicity of pyrethroids in creek, study finds

...erial applications can cover far more acreage than ground spraying from trucks, and are used if the human health risk from mosquito-borne infections is perceived to be greater than the risk of exposure to the pesticide. In this case, the decision to spray by air came after two dozen people in Sacramento C...

UCLA scientists strengthen case for life more than 3.8 billion years ago

...gone back to Greenland and done the study from the ground up, with much more data than existed at the time of the original paper. I'm much more confident today than I was in 1996 about the likelihood that this is evidence of early life. This is not 'smoking gun' evidence--we are not seeing fossils--but in e...

Tiny airborne particles are a major cause of climate change

...dies. Together with Kauffman, he used a network of ground sensors (AERONET) to measure the effect of aerosol concentration on cloud cover. Radiation absorption is less affected by meteorology, so if the skeptics are right and meteorology is the main influence, then the correlation between aerosol absorption...

Breaks in hibernation help fight bugs

...acteria such as E. coli and Salmonella in European ground squirrels, and how it affected their torpor patterns in relation to temperature. Microbial growth depends on temperature. Most bacteria grow faster when it is warm and much slower when it is cold. For animals exposed to Salmonella, which multipl...

Tropical forest CO2 emissions tied to nutrient increases

...espiration was measured using plastic tubes in the ground running into vented, closed chambers. According to the National Academy of Sciences, temperatures on Earth have risen by more than 1 degree F in the past century due to build-up of greenhouse gases in the atmosphere, primarily CO2. According to the...

Exxon Valdez oil found in tidal feeding grounds of ducks, sea otters

... This biologically diverse zone is a prime feeding ground for sea otters, ducks and other wildlife. Previously, scientists believed most of the oil was deposited on beaches at higher tide levels.> The researchers randomly dug 662 pits along 32 stretches of shoreline on northern Knight Island, one of...

Pollutant haze heats the Arctic

...d when warmer air aloft holds down cold air at the ground surface. "The pollution is similar to the haze we get in the Salt Lake Valley," says Garrett. "These [Arctic pollution] concentrations can get very high in winter and spring for exactly the same reasons Salt Lake has high pollution. The Arctic gets...

Tamed 11,400 years ago, figs were likely first domesticated crop

...ry easily propagated: A piece of stem stuck in the ground will sprout roots and grow into a plant. No grafting or seeds are necessary. Bar-Yosef, Kislev, and Hartmann suggest that this ease of planting, along with improved taste resulting from minor mutations, may explain why figs were domesticated some fiv...

Tarantulas produce silk from their feet

...ced tarantulas on a vertical glass surface. Though ground dwelling, these spiders can normally hang on to vertical surfaces by using thousands of spatulate hairs and small claws. However, the scientists noticed that when the spider started to slip down the surface, it produced silk from all four pairs of le...

Protowings may have helped bird ancestors cover rough terrain

Dial and two co-authors in the May 2006 issue of BioScience summarizes experimental evidence indicating that ancestral protobirds incapable of flight could have used their protowings to improve hindlimb traction and thus...
