Chemical Defense: Proteomic analysis of tree frog secretions reveals both salves and weapons akin to snake venom
SKIN DEEP The skin of amphibians like this European tree frog secretes chemicals that act as its first line of defense and may inspire novel pharmaceuticals. (Image and legend come from American Chemical Society)
The skin of tree frogs tells a story of peril. Constantly assau... more |

(Baby monkeys stressed by separation from mothers - image from BBC News)
Baby monkeys grew up anxious and anti-social after the stress of separation from their mothers, a study says.
It suggests changes to the brains of infant monkeys may be irreversible, and the study could be a model for humans.
An early shock to the system may leave the monkeys prone to a life of anxiety, po... more |

Maternal separation (MS), which can lead to hypothalamic pituitary adrenal (HPA) axis dysfunction and behavioral abnormalities in rhesus monkeys, is frequently used to model early adversity. Whether this deleterious effect on monkeys is reversible by later experience is unknown.
In order to unravel the mystery, a research group headed by Dr. MA Yuanye and HU Xintian from Kunming Instit... more |

Over the past years, natural antimicrobial peptides (AMPs) have attracted considerable interests as a new type of antimicrobial agents for several reasons including their relative
selectivity towards targets (microbial membranes), their rapid mechanism of action and, above all, the low frequency in selecting resistant strains. The research team led by Prof. Lai Ren of Kunming institute of z... more |

Rhesus macaque is the most widely used nonhuman primate animal in biomedical research. Though the oversea scientists have sequenced the genomes of Indian rhesus macaque, it is still not enough to get a global map of genetic variations in rhesus macaque.
A research group from Kunming Institute of Zoology, Chinese Academy of Sciences and Beijing Genomics Institute (BGI) did a collaborative se... more |
