The stresses that come with aging, chemotherapy treatments, and environmental exposures all threaten fertility. But what if there were a way to preserve women's limited egg supply? Researchers reporting on studies conducted in frog and mouse eggs in the Cell Press journal Molecular Cell on October 3rd may have found a way. The findings come at an important time when many women are waiting longer and longer to have children, renewing interest in the development of strategies to preserve...

African Clawed Frog Responsible For Spreading Deadly Fungus
2013-05-16 11:58:36

Brett Smith for redOrbit.com - Your Universe Online For years, scientists have been on the trail of a slippery culprit responsible for a deadly fungus, and they´ve finally found the culprit. The fungus, called Batrachochytrium dendrobatidis,“¯or ℠Bd´ for short, has played a role in the recent decline or extinction of 200 frog species worldwide. According to a new report in the open-access journal“¯PLOS ONE, long-suspected African clawed frogs have...

Cannibalistic Tadpoles Key To Understanding Digestive Evolution
2013-05-08 16:01:09

North Carolina State University A carnivorous, cannibalistic tadpole may play a role in understanding the evolution and development of digestive organs, according to research from North Carolina State University. These findings may also shed light on universal rules of organ development that could lead to better diagnosis and prevention of intestinal birth defects. NC State developmental biologist Nanette Nascone-Yoder, graduate student Stephanie Bloom and postdoc Cris Ledon-Rettig...

Salmonella Outbreak Traced To Pet Frogs

Brett Smith for redOrbit.com - Your Universe Online According to a new report from the Centers for Disease Control and Prevention (CDC), an outbreak of Salmonella infections from 2008 to 2011 was caused by small, aquatic pet frogs. "This was the first Salmonella outbreak associated with aquatic frogs, and in this case the frogs are often marketed as good pets for kids," lead author Shauna Mettee Zarecki, a public health advisor“¯with the CDC in Atlanta, told Reuters. The...

Zoologists of the University Jena clarify the role of the gene FOXN3 for the development of the clawed frog "Don't be a frog!" people say in jest when someone hesitates instead of acting straight away. However to be called a frog should actually be a reason to strengthen one's self-confidence. After all frogs are real winners "“ at least from the point of view of evolutionary biology: Nearly 6.000 species are known today. "In terms of numbers frogs are superior to all the other...

Proteins that import structural material and that regulate the import determine cell size Size matters when it comes to the nucleus of a cell, and now scientists have discovered the signals that control how big the nucleus gets. Nuclear size varies not only among different species, but also in different types of cells in the same species and at different times during development. In addition, cancer cells are known to develop larger nuclei as they become more malignant. Screening for cervical...

Rochester's 'Jumping Frog Lab' part of worldwide team decoding Xenopus tropicalis ROCHESTER, N.Y., April 29 /PRNewswire-USNewswire/ -- An African clawed frog has joined the spotted green puffer fish, the honeybee, and the human among the ranks of more than 175 organisms that have had their genetic information nearly completely sequenced. While the research could help scientists better understand the factors causing the vast die-off of amphibians around the globe, scientists are also...

A team of scientists led by the Department of Energy's Joint Genome Institute (JGI) and the University of California, Berkeley, is publishing this week the first genome sequence of an amphibian, the African clawed frog Xenopus tropicalis, filling in a major gap among the vertebrates sequenced to date. "A lot of furry animals have been sequenced, but far fewer other vertebrates," said co-author Richard Harland, UC Berkeley professor of molecular and cell biology. "Having a complete catalog of...

Atrazine, one of the world's most widely used pesticides, wreaks havoc with the sex lives of adult male frogs, emasculating three-quarters of them and turning one in 10 into females, according to a new study by University of California, Berkeley, biologists. The 75 percent that are chemically castrated are essentially "dead" because of their inability to reproduce in the wild, reports UC Berkeley's Tyrone B. Hayes, professor of integrative biology. "These male frogs are missing testosterone...
