Foot-and-mouth disease: A new antiviral stops the super-spreader in its tracks
Dr Tatsuya Nishi and Dr Kazuki Morioka from the National Institute of Animal Health at the National Agriculture and Food Research Organization, Japan, have been testing a promising treatment against foot-and-mouth disease virus (FMDV). Feeding pigs an antiviral drug (T-1105) may prevent any outbreak from spreading since it inhibits pigs from producing virus particles. Pigs are currently thought to be […]
Microbiomes – the key to a healthier planet?
Microbiomes are communities of microorganisms living on or in animals, helping to keep them healthy. Changes in the composition of microbiomes could make wildlife more vulnerable to diseases which may be zoonotic – transmissible to humans – so monitoring them could help us to predict outbreaks of disease and protect global health. Dr Andrew Bartlow and colleagues at the Los […]
Investigating the biopesticide activity of guayule resin
A team of researchers, led by Dr Manuel Carmona in the Institute for Regional Development at the University of Castilla-La Mancha, Spain, have unveiled recent discoveries about a unique plant called guayule. The silver-grey perennial shrub is an alternative source of natural rubber. Until now, guayule has not been commercially viable as its other co-products have not been considered to […]
Computational biology: How mathematical modelling can help cure cancer
Understanding how living cells work is difficult due to the number of varied and complex processes occurring in them. This complexity can be elucidated by breaking these processes down into simpler components and focusing on a particular mechanism. One approach to this study is to use mathematical equations – the basis of computational modelling. Dr Susan Mertins, the founder and […]
Thoroughbred racehorses: Speed machines and thermoregulatory specialists
Thoroughbred racehorses are exceptional athletes with explosive speed. At flat-out gallop, their working muscles generate heat faster than it can be lost, causing their core temperature to rise dramatically during racing. Through years of study, Meg Brownlow from Racing Australia and James Mizzi from Hong Kong Jockey Club have revealed the exceptional thermoregulatory mechanisms that enable racehorses to cope, including […]
Do phytoplankton hold the key to the evolution of marine biodiversity?
Life exploded in our oceans 250 million years ago, leading to the biodiversity that we see today. Before this point, however, the plant and animal life in our seas was considerably less diverse. Several theories have been proffered to explain this – often considering both habitat and climate changes – but very few studies have considered the role of phytoplankton. […]
Improving dog welfare: Helping owners decode their dogs’ behavior
Many dogs with behavioral problems are surrendered to shelters each year and are at risk of euthanasia. The Center for Canine Behavior Studies (CCBS) works with dog owners and canine professionals to gain a better understanding of canine behavior issues and the techniques that work best for treating these issues. This information is used to educate dog owners, veterinarians, and […]
Impact of dietary protein on cat health and wellbeing
Compared to dogs, cats require higher levels of protein in their diet to remain healthy. Based on current recommendations, commercially available cat food contains between 28% and 55% protein for cats of different ages and health conditions. Dietary protein levels are thought to influence disease susceptibility by affecting gut microbial communities. Dr Dayakar Badri and Dr Matt Jackson of Hill’s […]
Stress vulnerability and resilience: Insights from a novel mouse model
Stress and early life adversity alter the body’s stress response and are predisposing individuals to psychiatric disorders. Additionally, stress vulnerability and resilience have a genetic predisposition in humans due to variants of the FKBP5 gene. For in depth understanding of underlying mechanisms altering the stress-response network, valid animal models are needed. A novel mouse line developed at Taconic Biosciences and […]
Malaria modelling: An optimal control problem
Malaria, a life-threatening mosquito-borne disease, is a leading cause of death and infection in many developing countries. Using mathematical modelling, Professor Wandi Ding, Middle Tennessee State University, USA, and her colleagues investigate optimal control of malaria, using both the sterile insect technique and insecticide-treated nets. Their simulations show that a combination of both strategies results in a more rapid elimination […]
