Howie Choset's snakebot technology can navigate through three-dimensional terrains with enhanced flexibility and 'reach' ability. The robot's hyper-redundant mechanisms enable it to thread through tightly packed spaces without disturbing the surrounding areas.
Ethiopian wolf populations are threatened by rabies, which spreads rapidly among packs. Vaccinating surrounding dogs is a costly and difficult option, but researchers found vaccinating wolves themselves could increase survival rates. Developing an oral rabies vaccine for wolves may be a more effective solution.
A study of 24,690 British children found a dose-related association between maternal antibiotic exposure during pregnancy and increased risk of asthma, eczema, and hay fever. Another study on Alaskan sled dogs suggests that 'ski asthma' may be a model for exercise-induced airway injury in humans.
Dogs on a reduced-calorie diet lived up to 13 years, while those with high-calorie diets averaged 11.2 years. The study also found that lean body conformation and dietary restriction can help prevent chronic illnesses like osteoarthritis.
The National Human Genome Research Institute (NHGRI) has upgraded the priority of cow, dog, Oxytricha trifallax, and Trichoplax genomes to high or moderate based on medical and biological opportunities. The genome sequences are expected to speed up studies of these agriculturally important animals and have medical benefits for dogs.
Researchers have developed a gene therapy approach to treat mucopolysaccharidosis VII, a disorder affecting multiple organ systems, in dogs. The treatment involves four intravenous injections of a retroviral vector expressing canine beta-glucuronidase, resulting in normal enzyme activity and near-normal mobility in treated dogs.
A study found that children exposed to dogs and cats in the home have a significantly reduced risk of developing common allergies, with exposure levels reducing allergy rates by up to 45%. The research suggests that early exposure to endotoxins from pets may help the immune system develop a different response, making it less likely for...
A study by Pauline Entin, PhD, found no significant gender difference in running speed for horses, which contradicts the assumption that men are faster than women. In contrast, female horses have been successful in premier events and dogs show a similar lack of gender-based segregation in racing.
A recent study found that dog collars fitted with deltamethrin resulted in a 42% reduction in transmission of zoonotic visceral leishmaniasis to children and a 54% drop in infection rates among dogs. This alternative control method is more practical and effective than current methods, such as dog culling and spraying insecticide.
Researchers have discovered genetic mutations in dogs that mirror the genetic mutations of humans with inherited blindness, providing new insights into photoreceptor cell degeneration. The study has potential implications for treating both canine and human retinal diseases, including progressive retinitis pigmentosa.
Bats are the leading cause of human rabies in the US, with tiny bites going unnoticed. The study found it unlikely for bat rabies to be transmitted through the air or from an infected animal like a cat or dog. Dr. Gibbons advises seeking emergency care if direct contact occurs.
Researchers have discovered a genetic mutation in English mastiffs that causes retinal dysfunction and degeneration, mirroring human dominant retinitis pigmentosa. The study aims to find treatments and cures for inherited forms of blindness in humans by testing therapies first in dogs.
A team of researchers is tracking the health of rescue dogs and their handlers who searched at the World Trade Center and Pentagon. The study aims to identify potential long-term consequences, including cancer and mental health issues, and provide assistance to those affected.
Researchers found that hip laxity is a solid risk factor for canine arthritis, which affects an estimated 70-80 percent of dogs in certain breeds. Selective breeding to avoid high-laxity individuals could slash the incidence of canine arthritis within 10 years.
Researchers at the University of Illinois have developed a simple protein test to detect telomerase activity in cancerous cells of dogs and cats. The test has shown promising results in diagnosing malignant tumors in pets, with high accuracy rates compared to traditional diagnostic methods.
Researchers developed a mathematical model that suggests barring domestic animals from bedrooms can significantly reduce Chagas disease transmission. By analyzing household dynamics, they found keeping dogs in bedrooms is the worst thing for households, while excluding infected dogs from sleeping areas virtually eliminates transmission.
Keeping chickens and dogs out of bedrooms can reduce Chagas disease risk by reducing the bug population, say Science researchers. Removing infected dogs from households nearly wipes out transmission of the parasite.
A new study has revealed that Italian wolves have maintained a pure population despite facing threats such as competition for food and space. The researchers analyzed mitochondrial DNA samples from over 100 Italian wolves, finding unique sequences that indicate the species has remained genetically distinct from feral dogs.
A study by Mississippi researchers found that flea collars with organophosphate insecticides can release residues on dogs' fur, which can then be transferred to humans. The levels of these residues vary depending on the collar's design, and experts are urging parents to keep children away from pets when new collars are used.
Researchers found that three out of 11 wild wolves carried the enzyme corticosteroid-induced alkaline phosphatase, which is also found in dogs. This enzyme reflects long-term stress and indicates the presence of hepatic disease in the wolves. In contrast, captive wolves had no enzyme, suggesting they are healthier.
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 discovered Cryptosporidium and Giardia parasites in 7.3% and 11.7% of stool samples from dogs, with puppies under 30 weeks old most affected. Despite no visible symptoms, these parasites can cause serious illness in humans.
Researchers at Cornell University have discovered a genetic correlation between dog blindness and a similar human disease, potentially leading to new treatments for human eye disorders. The study identifies the canine version of the human RP17 gene defect, which could lead to gene therapy methods for both dogs and humans.
A genetic map of dogs was constructed using 150 microsatellite markers, revealing the organization of genes and traits on the canine genome. The study has significant implications for understanding human diseases such as cancer, epilepsy, and bleeding disorders.
Researchers are documenting the existence of seizure-alert dogs that claim to detect seizures before they strike, offering hope for people with epilepsy. The study aims to determine if these phenomena are real and reliable, and how dog trainers approach training such dogs.
Scientists at the University of Wisconsin-Madison have successfully transplanted nervous system cells into dogs with diseased spinal cords, achieving significant myelination and growth. This breakthrough finding offers new hope for multiple sclerosis treatment and may be applicable to other demyelinating disorders.
