Masturbation is far more important in the timeline of human evolution than ever previously thought. In fact, we might not be here at all if it weren’t for primates masturbating thousands of years ago, a new study has claimed. New research from the Proceedings of the Royal Society B has focused on the effects of masturbating in male primates and its effects on ensuring reproductive methods. “Masturbation is common across the animal kingdom but is especially prevalent amongst primates, including humans,” the study authors said in a statement.

That’s because it “allows males to shed inferior semen, leaving fresh, high-quality sperm available for mating, which are more likely to outcompete those of other males.” It also helped male primates “by cleansing the urethra (a primary site of infection for many STIs) with ejaculate”. Things were less clear with female primates, with the study authors stating that “more data on female sexual behavior are needed to better understand the evolutionary role of female masturbation.” “Our findings help shed light on a very common, but little understood, sexual behavior,” said lead author Dr. Matilda Brindle, of University College London. “The fact that autosexual behavior may serve an adaptive function, is ubiquitous throughout the primate order, and is practiced by captive and wild-living members of both sexes, demonstrates that masturbation is part of a repertoire of healthy sexual behaviors.” Have your say in our news democracy.

New York City and much of the tri-state area has been blanketed by smoke caused by raging wildfires in Canada. The poor air conditions have continued to spread throughout the northeastern United States. On Wednesday (7 June), New York City was ranked number one for the worst air quality in the world, with the Air Quality Index (AQI) at 342 and air pollution levels described as “hazardous”. Many officials have since advised people to limit their time outdoors and wear masks to protect themselves from the smoke. Public schools have also cancelled outdoor activities, including recess and gym classes. Follow for live air quality alert updates. Experts estimate that each hour of exposure to wildfire smoke is equivalent to smoking cigarettes continuously for the same amount of time, but that’s just for humans. Imagine how wildfire smoke affects our beloved pets? In fact, poor air quality may pose an even greater risk to animals because of their much smaller size. Here’s how to protect your pets from wildfire smoke as air quality alerts continue throughout New York. The biggest danger to pets comes from the fine particles found in air pollutants, which can get into the lungs and cause a variety of health issues – like eye irritation or respiratory problems. Some of the most vulnerable pets are older animals suffering from heart or lung disease. Certain breeds, such as pugs and bulldogs, may be especially at risk of inhaling too much smoke, according to the American Kennel Club. There are several signs that indicate a pet may be having problems from poor air quality. According to the US Environmental Protection Agency (EPA), some of the symptoms include coughing or gagging (particularly in cats), red or watery eyes, inflammation of the throat or mouth, trouble breathing, fatigue or weakness, and reduced appetite or thirst. The first thing pet owners should do at the sign of wildfire smoke exposure is to call their veterinarian. In the meantime, saturating a cotton ball with lukewarm water and squeezing it over an animal’s eyes can help with irritation and flush them out. In order to protect pets from wildfire smoke, try to reduce their exposure as much as possible. For outdoor pets like horses or livestock, bring these animals into a room with good ventilation, such as a utility room or garage. The EPA also states that smoke is especially tough on pet birds because of the construction of their respiratory systems. Birds that are exposed to too much smoke may act lethargic or struggle to breathe, and may sit in the bottom of their cages. Keeping the indoor air clean can also help protect animals against wildfire smoke. Pet owners should keep their windows closed and their pets in a room with an air purifier. Activities such as frying foods, burning candles, or using a fireplace can also be bad for pets because it adds air pollutants to your home. If necessary, pet owners take short potty breaks with their dog or cat before returning inside. It’s probably not best to go on a long run with an animal when air quality alerts are in effect, either.
