A tree representation of genetic relationships between H3N2 influenza viruses from 2002 to 2007. The thicker line on the tree represents the successful evolutionary trunk lineage that gives rise to all influenza strains over time. The tree is colored according to estimated geographic location, indicating high permanence of the trunk in China and Southeast Asia.

Figure 2. Stenogobius hawaiiensis (O‘opu naniha) is one of the five species of stream gobies found on Hawaiian Islands. Its pelvic fins are fused and form a sucking disc, a common feature for all gobies. Several species of stream gobies use that disc for attaching to stones in rivers and even for climbing on vertical rock surfaces behind waterfalls.

They began to develop deep in the ocean through active volcanic processes and eventually emerged above the water creating completely new habitats for different types of organisms. How numerous species of plants and animals colonized these novel…

How will East Africa address its food crisis?

by Saul Daniel Ddumba Over decades, food production in East Africa has been affected by a changing climate, limited use of fertilizers and pest control, inadequate food storage facilities and complex marketing channels that together have led to chronic malnutrition, hunger and poverty (Figure 1). We are also uncertain about how future changes in climate will…

Stopping global food waste might be harder than you think

By Alexandra Heeney Do you usually buy your groceries in a single shopping trip each week? Are there large stacks of fruit and vegetables on display at the grocery stores you frequent?
