Contact Information Available for logged-in reporters only Newswise The Smithsonians National Zoo and Conservation Biology Institute celebrated several births recently. During the past several weeks, 31 new residents have been born, many of which were endangered species. A short-eared elephant shrew was born May 8 at the Zoos Small Mammal House. The short-eared elephant shrew is the smallest of the 17 living species of elephant shrew, weighing between less than one-third of an ounce and 1.5 ounces at birth. It is too early to determine the babys sex. Although the tiny shrew has been active since birth, it stayed hidden for the first few days of its life, which is normal. Keepers are now getting more glimpses of the shrew as it comes out of its den to explore. These insect-eating mammals name comes from their noses resemblance to the trunk of an elephant. A fishing cat, recently named Hunter, was born April 15 on Asia Trail. Inhabiting India and Southeast Asia, fishing cat populations are declining, and the species is considered endangered because of habitat loss and hunting for food and fur. The first pair of twin fishing cats was born at the National Zoo in May 2012. Only … Continue reading →

West Lafayette, IN (PRWEB) June 13, 2014 High school students from Minnesota, Oregon, Virginia and Washington have been selected by the Center for Excellence in Education (CEE) to represent the United States at the 2014 International Biology Olympiad (IBO) next month in Indonesia. The four received gold medals during the CEE's 12th annual USA Biology Olympiad national finals hosted by Purdue University and will advance to the IBO on July 6-13. Team USA members selected during an awards ceremony Thursday (June 12) are: They will travel to Bali, Indonesia, to compete at the IBO, a worldwide event involving students from 63 countries. Kathy Frame, director of the USABO and special projects for the CEE, and Clark Gedney, director of the BioMedia Center for Instructional Design at Purdue, will accompany Team USA at IBO. This marks the fifth consecutive year that Purdue has co-sponsored the finals with CEE. Silver medalists at the USABO are: Grace Chen, Bridgewater-Raritan Regional High School, Bridgewater, New Jersey; Michael Gao, Freehold High School, Freehold, New Jersey; Siddarth Guha, Dulles High School, Sugar Land, Texas; and Catherine Wu, Canyon Crest, San Diego.

Worcester, Mass. (PRWEB) June 12, 2014 If a virus has got your goat, the sooner you know, the better. Especially if its the Caprine Arthritis-Encephalitis Virus (CAEV), which can spread undetected through a herd, reducing the milk production and lifespan of one of the most important farm animals in the developing world. Creating a simple, inexpensive way for farmers to test their goats (or sheep, which are also susceptible) for CAEV is the goal of the first team of undergraduates from Worcester Polytechnic Institute (WPI) to enter the undergraduate International Genetically Engineered Machine (iGEM) competition. iGEM is a global synthetic biology program that challenges students to create biological machines that work within living cells to produce a desired product or process. CAEV is slow to cause visible symptoms, so it can hit many animals before a farmer knows the herd is infected. Animals sick from CAEV may develop severe joint pain that limits mobility, a potentially fatal pneumonia, or a deadly swelling of the brain. There is no cure or vaccine, so animals suspected of having CAEV are either isolated or destroyed. The virus can be transmitted through saliva, nasal discharge, and other excretions, and is often passed from mother … Continue reading →
