Growth in the sea comes down to a struggle for iron

...ily. Since prevailing winds tend to blow iron rich dust off the Asian continent into the Pacific, it may be that phytoplankton closer to the source of that dust may be primed to respond differently. Wells and his colleagues will be studying the possibility tha...

What's really making you sick? Plant pathologists offer the science behind Sick Building Syndrome

...h in its infancy to control it." Apart from mold, dust and other antigens also cause SBS. This makes SBS a complex problem and requires objective inspections for possible causes to detect and manage SBS. Skaria cites a need for more plant pathologists and mycologists to study building-related mold growth...

NASA probe could reveal comet life, scientists claim

...ed from a mixture of ices and organic interstellar dust at the time the solar system was formed some 4.6 billion years ago. "This material is quite porous, so it is daring again to predict that subsurface ponds or lakes form transiently due to heat penetrating the exterior crust. We can thus expect biolo...

Life detection instrument passes key test on road to Mars

...de of grass or a bug for ages, and contending with dust and temperature extremes that left her either freezing or sweating, Skelley ran 340 tests that proved the instrument could unambiguously detect amino acids, the building blocks of proteins. More importantly, she and Mathies were able to detect the pr...

Pillows - a hot bed of fungal spores

...: "We know that pillows are inhabited by the house dust mite which eats fungi, and one theory is that the fungi are in turn using the house dust mites' faeces as a major source of nitrogen and nutrition (along with human skin scales). There cou...

The dangerous legacy of lead

...where children come in contact with lead paint and dust and, as a result, may experience intellectual impairment, behavioral problems and lifelong health issues. The effects of lead in children are irreversible, so public health officials are primarily focused on preventing these exposures. ...

UCR environmental scientists propose chemical solution to cleaning California's Salton Sea

...hrink, exposing lake sediments that could generate dust and worsen air quality. Fish and fish-eating birds would disappear in 10-30 years, and be replaced perhaps by birds that eat brine shrimp. And the sea would continue to smell, which might even get worse. Doing something to address the Salton Sea's pr...

NASA study solves ocean plant mystery

...ater is mixed by the wind. Iron also can come from dust blowing in the air. Approximately half of the photosynthesis on Earth occurs in the oceans, and the remainder on land. Ocean and land plants share the same basic requirements for photosynthesis and growth. These requirements include water, light an...

Iron critical to ocean productivity, carbon uptake

...from the air, but it also enters the ocean through dust deposited by the wind. Windstorms blowing sand and dust off large deserts are a major source of iron for the world's oceans. "It's like dumping a load of G...

This is the first study to show a relationship between specific airborne fungal spores and an increased risk for multiple allergies in children, the UC team reports in an upcoming edition of P...

Allergy battle could be won in five years, says scientist

"Allergens from pollen or house dust mites are inhaled and then dissolve the binding material between the cells that form these protective linings; they can then enter the body by passing between the cells to cause an allergic response. "The drugs we are developing -- called Allergen ...
