A veterinary parasitologist and his team have demonstrated that dogs are definitive hosts for Neospora caninum, a single-celled parasitic organism causing cattle abortions. This discovery has led to recommendations for improved cattle management strategies to reduce economic losses estimated at $35 million per year.
Researchers have found that the Earth's inner core consists of two distinct parts: a lower area surrounded by an uneven upper layer with different material properties. This discovery is likely to affect the current model of how the Earth and its magnetic field came into being.
The Georgia Institute of Technology has partnered with Vivendi to develop innovative technologies for urban water and wastewater management. The partnership aims to improve environmental and economic issues related to water management, with a focus on drinking water treatment and distribution.
Researchers have found that cells in the developing limb provide a key signaling molecule that defines motor neuron identity. The study reveals that motor and sensory neurons express the same genes, suggesting a coordinating role for the target region in constructing proper connections within the spinal cord.
Researchers are exploring transgenic mosquitoes capable of transmitting nitric oxide, which can kill parasites. This approach may offer a key to disrupting the complex relationship between mosquitoes and malaria parasites.
Researchers at Chiron Corporation have identified a protein molecule (CD81) that binds to the hepatitis C virus (HCV), providing clues on how the virus infects human cells. This discovery has significant implications for the development of new vaccines and therapeutics to prevent and treat chronic HCV infection.
Researchers from Virginia Tech are training Jamaican agricultural personnel to use GIS in integrated pest management, reducing pesticide use and environmental harm. The system helps analyze spatial patterns of variables relevant to solving pest management problems.
A Cedars-Sinai researcher has identified a gene associated with malignancy in brain, liver, breast, colon, kidney, and reproductive organs, but not in healthy adults. The discovery could lead to the development of a method to block the gene's expression using antisense technology, potentially stopping cancer before it spreads.
University of Michigan scientists have developed a new generation of viral vectors that deliver the dystrophin gene to the muscles of adult mice with muscular dystrophy. The new vectors, called 'gutted' viruses, are stripped of most of their original genes to make room for the large dystrophin gene and reduce immune response.
A new Johns Hopkins study shows that ecstasy users are at risk of developing brain injury due to the drug's impact on serotonin-releasing nerves. The research found significant losses in these nerve cells with greater use, suggesting potential long-term damage.
