Across Appalachia and the Rust Belt region, including throughout the city of Pittsburgh, former industrial sites are being transformed into new neighborhoods, research centers and technology hubs.
The malaria parasite is able to detect changes in its host's environment and respond by increasing the production of sexual forms capable of being transmitted to mosquitoes. A study led by the Barcelona Institute for Global Health (ISGlobal) identifies the molecular mechanism underlying this process. The findings, published in Nature Microbiology, answer what has been one of the major unanswered questions in malaria research for decades.
Across South Africa, natural springs are more than sources of freshwater. Some are places of healing, spiritual cleansing and rituals, where communities collect water and maintain longstanding cultural connections with the environment. For example, during cleansing rituals, people bathe in or collect spring water as a way of seeking spiritual renewal, healing and protection. These are known as sacred springs.
The first storm warning for the Miami area wasn't issued until only a few hours before the powerful cyclone made landfall just south of downtown, leaving residents with little time to prepare for what would become the hurricane of their nightmares.
The electronic properties of materials are typically determined by their structure under normal, undisturbed conditions, when they are in a state known as equilibrium. Intense light beams, however, can temporarily reshape a material's electronic band structure (i.e., the range of energy states available to electrons), potentially giving rise to new electronic behaviors.
Cells rely on complex signaling networks in which different molecular pathways communicate with one another. Small GTPases act as molecular switches in these networks, controlling diverse cellular processes such as intracellular transport and cell morphogenesis. Although crosstalk between different families of small GTPases is established in animal cells, whether and how such crosstalk occurs in plants has remained largely unknown.
