| Among the over 4,000 amphibian species worldwide, most distribute in rain forests, creeks, mountains, plateaus, or deserts, but almost no one survives in environments with high salinity. As an exception, the crab-eating frog, Fejervarya cancrivora, a species native to south-eastern Asia, is the only known modern amphibian tolerates hyperosmotic external conditions. Compared with other species w... more |

| Cockroach, a common insect pest in the urban inner-city environment, is an important source of inhalant indoor allergen resource, and has been recognized as a major cause of asthma. In 1964 Bernton and Brown first clearly documented the skin reaction test of cockroach allergens. In 1979 the relationship between asthmatic patients and inhalant cockroach allergens was conformed. According to the ... more |

| Butterflies are exceptionally diverse but their potential as an experimental system has been limited by the difficulty of deciphering heterozygous genomes and a lack of genetic manipulation technology. In order to develop butterflies as new models for exploring such topics as genetic mechanism of morphological evolution, the researchers from the Kunming Institute of Zoology (KIZ), Chinese Acade... more |

| Breast cancer is a common malignant tumor. The advance of breast cancer treatments is hindered in part by challenges in translating to humans the successes achieved indistantly related rodent species. To bridge that evolutionary gap, scientists have begun to turn to an alternative model organism, the tree shrew (Tupaiabelangerichinensis). Tree shrews have increasingly become an attractive exper... more |
