Scientists at The University of Manchester have found evidence of the genetic basis of the evolutionary arms-race between parasitoids and their aphid hosts. The researchers studied the reaction of aphids when a parasitic wasp with genetic variation laid eggs in them. They found that different genotypes of the wasp affected where the aphids went to die, including whether they left the plant host entirely. The team also found an example of the emergence of a shared phenotype that was partly...

Female Pit Vipers Give Birth Without Mating

Brett Smith for redOrbit.com - Your Universe Online In what could be the ultimate act of feminism, wild female North American pit vipers have been shown to give birth without mating, according to a new report published in the Royal Society's Biology Letters. A phenomenon, known as facultative parthenogenesis (FP), has been observed in captivity before and the report asserts that it can occur regardless of the presence of male individuals. “In these populations, males are...

Researchers at Nationwide Children's Hospital report a gene therapy strategy that improves the condition of a mouse model of an inherited blood disorder, Beta Thalassemia. The gene correction involves using unfertilized eggs from afflicted mice to produce a batch of embryonic stem cell lines. Some of these stem cell lines do not inherit the disease gene and can thus be used for transplantation-based treatments of the same mice. Findings could hold promise for a new treatment strategy for...

By Mick Kulikowski, North Carolina State University In a finding that upends decades of scientific theory on reptile reproduction, researchers at North Carolina State University have discovered that female boa constrictors can squeeze out babies without mating. More strikingly, the finding shows that the babies produced from this asexual reproduction have attributes previously believed to be impossible. Large litters of all-female babies produced by the "super mom" boa constrictor show...

Shark pups born to virgin mothers can survive over the long-term, according to new research published Jan. 25, 2010 in the Journal of Heredity. The study shows for the first time that some virgin births can result in viable offspring. Genetic analysis led by a Field Museum scientist working with numerous colleagues has confirmed the first known case of a virgin female shark producing multiple offspring that survived. Two daughters of the white-spotted bamboo shark are now more than five years...

Hwang Woo-Suk, a South Korean cloning expert, was given a suspended prison sentence on Monday after a court found him guilty of embezzlement and other charges stemming from faking results of stem-cell experiments. However, Hwang was found not guilty of defrauding private entities that contributed funds to his research. South Korean prosecutors said they would appeal the not guilty ruling for fraud, as they had originally sought a four-year jail term when Hwang went on trial in June 2006....

Researchers at North Carolina State University have found that intrauterine growth restriction (IUGR), which results in low birth weight and long-term deleterious health effects in cloned swine, is linked to a type of gene - known as an imprinted gene - found only in placental mammals. Imprinted genes play an important role in the normal fetal development of all mammals, and this study could have future implications for the study of IUGR in humans. Of the 20,000-25,000 genes in the human...

In the emerging field of regenerative medicine one topic that has earned its fair share of notoriety is the issue of embryonic stem cell research. Stem cells are characterized by the ability to renew themselves through cell division and differentiate into a diverse range of specialized cell types. Since stem cells can be grown and transformed into specialized cells with characteristics consistent with various tissue such as muscles or nerves, their use in medical therapies has been prized....

The Red Swamp Crayfish, Procambarus clarkii, also commonly known as the Red Swamp Crawfish, Louisiana Crawfish or Louisiana Crayfish, is a freshwater crayfish species. Charles Frédéric Girard named the genus in honor of John H. Clark, who in 1851 surveyed the U.S. American border. Although native to the southeastern United States, it is also found on other continents, where it is considered an invasive nuisance. The Red Swamp Crayfish natively ranges along the Gulf coast from...
