Argentine ants are taking over the world or at least the nice temperate parts. They've spread into Mediterranean and subtropical climates across the globe in sugar shipments from Argentina, and no native ant species has been known to withstand their onslaught until now. A group of Stanford University ...

(PhysOrg.com) -- Argentine ants are taking over the world – or at least the nice temperate parts. They've spread into Mediterranean and subtropical climates across the globe in sugar shipments from Argentina, and no native ant species has been known to withstand their onslaught – until now. A group of ...

Scientists from the Helmholtz Centre for Infection Research (HZI) in Braunschweig, Germany have discovered a new, hitherto unknown mechanism of Salmonella invasion into gut cells: In this entry mode, the bacteria exploit the muscle power of cells to be pulled into the host cell cytoplasm. Thus, the strategies Salmonella use ...

Like some bad science-fiction movie, Philippine fishermen are encountering strange alien creatures: tough, speckled fish with sharp spines that tear and rip their nets.

Australian scientists using new image and cell technologies have for the first time caught malaria parasites in the act of invading red blood cells. The researchers, from the Walter and Eliza Hall Institute in Melbourne, Australia, and the University of Technology, Sydney (UTS), achieved this long-held aim using a combination ...

A new field study confirms that an invasive weed called medusahead has growth advantages over most other grass species, suggesting it will continue to spread across much of the West, disrupt native ecosystems and make millions of acres of grazing land almost worthless.

CORVALLIS, Ore. A new field study confirms that an invasive weed called medusahead has growth advantages over most other grass species, suggesting it will continue to spread across much of the West, disrupt native ecosystems and make millions of acres of grazing land almost worthless. The ...

Intestinal worms sidestep the immune system by inducing the development of suppressive T cells, according to a study published on September 27th in the Journal of Experimental Medicine.
