How can blue whales, the largest animals on the planet, survive by feeding on krill, shrimp-like creatures that are the size of a penny? According to UCLA life scientists, it’s all a matter of dimensions. In findings published May 30 in the journal Nature, the researchers demonstrate for the first time that the relationship between […]

Highway through Amazon worsens effects of climate change, provides mixed economic gains

Paving a highway across South America is providing lessons on the impact of road construction elsewhere. That’s what a University of Florida researcher and his international colleagues have determined from analyzing communities along the Amazonian portion of the nearly 4,200-mile Interoceanic Highway, a coast-to-coast road that starts at ports in Brazil and will eventually connect […]
