Study finds the air rich with bacteria

...borne bacteria. Does it come from nearby farms and water treatment plants, or is it imported by the wind from another state or country?" The team also determined that location was not as strong a source of microbial variation as time and weather. Specifically, the time of the year during the 17-week tes...

"Our hypothesis is that once a biofilm starts in a wound it interferes with the normal healing process and becomes very tough to eradicate," said Phil Stewart, Ce...

The Gormley statues not only provide a perfect anchor point but sheltered parts of the figures such as the inner thigh protect them from extreme harsh conditions. "This particular breed is a ...

Ocean temperature predicts spread of marine species

...ser together than in colder water, since in warmer water dispersal distances tend to be shorter," O'Connor said. While a one degree increase in temperature at the ocean surface means larvae will travel a shorter distance in warm seas, the effect is more severe when temperatures are below about 59 degree...

Steep oxygen decline halted first land colonization by Earth's sea creatures

Parasitic plants sniff out hosts

...First the researchers placed dodder seedlings in a water vial at the center of a filter paper disk. A tomato plant was placed near the edge of the disk and the dodder plant was allowed to grow and attempt to locate its host. Dodder plants search for hosts by growing and moving in a circular pattern. In ...
