Locusts help uncover the mysteries of smell

By looking into the brains of locusts, researchers have determined how one smell can affect another, and how a locust can recognize a smell even though its brain activity looks different depending on the context. View the source article

Field test for dog Leishmania exposure evaluated

Dogs infected with Leishmania infantum, a parasite transmitted by the sand fly Phlebotomus perniciosus, are at risk for spreading leishmaniasis infections to humans. A new test provides an easier-than-ever way to test dogs for exposure to P. perniciosus sand flies, and could be used in monitoring the effectiveness of sand fly control efforts.

Empathetic dogs lend a helping paw

Many dogs show empathy if their owner is in distress and will also try to help rescue them. Scientists have just tested whether there is truth in the notion that dogs have a prosocial and empathetic nature. View the source article

Transmission of NDM bacteria between dogs and humans established

In 2015, a New Delhi-metallo-beta-lactamase (NDM) Escherichia coli bacteria was discovered in two Finnish dogs. A new article reveals that the dogs' owner did also carry the bacterium. This is presumably the first time in the world that the transmission of NDM-bacteria between a dog and a human has been reported. View the source article

Kissing bugs kiss their hiding spots goodbye, thanks to tiny radio transmitters

Researchers have successfully attached miniature radio transmitters to kissing bugs and tracked their movements. Also known as triatomine bugs, kissing bugs transmit the pathogen that causes Chagas disease in humans and animals. They typically move at night and hide during day, and uncovering their secretive movements could play a key role in reducing their impact as a disease vector. View the source article

Wolf reintroduction: Yellowstone's 'landscape of fear' not so scary after all

After wolves were reintroduced to Yellowstone National Park in the mid-1990s, some scientists thought the large predator reestablished a 'landscape of fear' that caused elk, the wolf's main prey, to avoid risky places where wolves killed them. But according to recent findings, Yellowstone's 'landscape of fear' is not as scary as first thought. View the source article

How do horses read human emotional cues?

Scientists demonstrated for the first time that horses integrate human facial expressions and voice tones to perceive human emotion, regardless of whether the person is familiar or not. View the source article

Dogs understand what's written all over your face

Dogs are capable of understanding the emotions behind an expression on a human face. This study is the latest to reveal just how connected dogs are with people. The research also provides evidence that dogs use different parts of their brains to process human emotions. View the source article

Dogs can detect agricultural diseases early

Laurel wilt disease has had a devastating effect on the avocado industry in South Florida in past harvest seasons. Early detection can be instrumental in deterring a widespread infection. The use of scent-discriminating dogs has shown to offer the avocado industry legitimate signs of hope in their fight against the spread of the disease throughout their groves. View the source article

Dogs can be a potential risk for future influenza pandemic

Dogs are a potential reservoir for a future influenza pandemic, according to a new study. The study demonstrated that influenza virus can jump from pigs into canines and that influenza is becoming increasingly diverse in canines. View the source article

Upgrading the toolbox for Duchenne muscular dystrophy research with a new rabbit model

Research to improve our understanding of Duchenne muscular dystrophy (DMD), and the development of new therapies, has previously relied on mouse models. However, physiological differences between the two species has limited how successfully findings in mice can be applied to humans. A newly developed rabbit model, created through the use of CRISPR/Cas-9 genome editing, exhibits greater clinical similarity to human patients than the mouse models currently in use, with huge potential to advance DM

How to achieve a peaceful coexistence between wolves and humans

The persecution of wolves in order to remove them from human settlements has culminated in their near-disappearance in numerous European countries, like Spain and Sweden. Following a recovery of the species, a team of scientists has determined what geographic areas in the Scandinavian country would be most suitable for a redistribution of the specie's range, in the interests of increasing the social acceptance of wolves.

Blame the mother's gene: Discovery for a blinding canine eye disease

A new gene for canine congenital eye disease has been identified. Defective RBP4 leads to vitamin A deficiency and abnormal eye development during pregnancy. The study defines a novel recessive mode of maternal inheritance, which may underlie other types of birth defects. View the source article

Tick bite protection: New CDC study adds to the promise of permethrin-treated clothing

The case for permethrin-treated clothing to prevent tick bites keeps getting stronger. In new experiments, clothing treated with an insecticide known as permethrin had strong toxic effects on three primary species of ticks known to spread disease-causing pathogens in the United States. Exposure to permethrin interfered with the ticks' ability to move properly, making them sluggish and likely interfering with their ability to bite. View the source article

Cause of E. coli beach closings? Gulls

Researchers have recently published results identifying the major sources of E. coli breakouts on several beaches on Lake Michigan. They have also researched an effective method of reducing the breakouts and the resulting beach closings. View the source article
