Crickets that are exposed to human drugs that alter serotonin levels in the brain are less active and less aggressive than crickets that have had no drug exposure, according to a new study led by researchers from Linköping University. The findings have been published in Scientific Reports.
Researchers from Washington University in St. Louis have mapped the regions of the brain in mormyrid fish in extremely high detail. The new measurements can help illuminate longstanding questions in neuroanatomy. As brains get bigger, do all regions of the brain scale up in a predictable way? Or does natural selection act independently on separate regions of the brain -- such that certain parts of the brain become enlarged in animals that have extra reasons to use them?
A vaccine used to prevent dogs from contracting the deadly, parasitic disease canine leishmaniasis also can be used to treat currently infected dogs, found Morris Animal Foundation-funded researchers at the University of Iowa, providing a new avenue of treatment for millions of infected dogs globally.
Scientists have developed a completely automated technique for real-time detection of sleep/wake states in freely moving mice, according to a study by Karim Benchenane, Sophie Bagur and colleagues at the National Centre for Scientific Research in Paris, publishing on November 8 in the open-access journal, PLOS Biology.
Goffin's cockatoos can tear cardboard into long strips as tools to reach food -- but fail to adjust strip width to fit through narrow openings, according to a study published Nov. 7, 2018 in the open-access journal PLOS ONE by A.M.I. Auersperg from the Medical University of Vienna, Austria, and colleagues.
Scars left by orca attacks indicate that most victims are young whales on the first trip from breeding to feeding grounds. Increasing numbers of scars may mean that there are more orcas in the Southern Pacific, researchers say.
Vatinoxan reduces the adverse effects on the cardiovascular system of pharmacological agents used for animal sedation and anaesthesia. Also, other drugs achieve their therapeutic effect faster when administered simultaneously with vatinoxan.
The American Association of Feline Practitioners (AAFP) today released the AAFP Consensus Statement, 'Feline Feeding Programs: Addressing Behavioral Needs to Improve Feline Health and Wellbeing' and accompanying client brochure to the veterinary community. The Consensus Statement, published in the Journal of Feline Medicine and Surgery, explores the medical, social, and emotional problems that can result from the manner in which most cats are currently fed.
Dogs could be trained to sniff out malaria in people according to new research aimed at preventing the spread of the deadly disease.
A canine cognition test could help organizations that train working dogs identify the dogs that are most likely to succeed, according to new research led by the University of Arizona. If organizations could better predict which dogs will succeed in working roles, it could save thousands of dollars in training costs and ensure people in need get dogs faster.
