Using tranquillisers on racehorses is ethically questionable and puts horses and riders at risk

Paul McGreevy, University of Sydney and Cathrynne Henshall, Charles Sturt UniversityAustralia’s horse racing industry is in the spotlight after recent allegations of tranquilliser use on horses so they can be “worked” (exercised) between race days. A recent ABC report stated workers in the Australian racing industry allegge horses are being routinely medicated for track work at the peril of rider and horse safety. Using tranquillisers on horses during training and management may not be illegal but this could breach nationwide racing rules. The prevalence of the practice is not clear but many industry insiders report it as common. Racing Australia had “recently become aware” of the use of acepromazine for track work and had begun collecting data about the practice, but had not been made aware of any complaints or concerns. What medications are horses given? Horses may be given a low dose of a tranquilliser, most commonly acepromazine. This makes their behaviour easier to control in certain situations, such as when they’re being examined by a veterinarian. This drug must be prescribed by an attending veterinarian, and it can calm unfriendly and apprehensive animals. This could assist with making excited, hyperactive horses easier to control and less likely to buck, rear or put people at risk of injury from uncontrolled...

Number of Monarch Butterflies Wintering in Mexico is Way Up–Doubling the Forest Acreage Over Last Year

Monarch butterflies in Michoacán, Mexico forest by Alex GuillaumeThe number of monarch butterflies overwintering this year in Mexico has nearly doubled, according to the annual census released last week by the World Wildlife Fund in Mexico and their partners.During the last few months in 2025, the population of eastern monarchs occupied 4.42 acres of central Mexico’s forests—up from 2.22 acres during the previous winter.The encouraging survey was conducted with help from Mexico’s National Commission of Protected Natural Areas and local communities, and it serves as an important indicator of the health of a monarch population that has been clawing its way back from dangerously low levels this century.“It’s now time to turn this year’s increase into a lasting trend with an all-hands approach where governments, landowners, conservationists, and citizens continue to safeguard critical habitats along the monarch’s North American migratory route,” said Jorge Rickards, director general of WWF Mexico, who recognized the key role of local communities and the government of Mexico in conserving the forest that provides an annual respite to this iconic species.Scientists attribute much of this year’s population growth to better weather conditions in 2024—with less severe drought than in previous years along their migration route from the U.S....
