Horses are smarter than previously thought, researchers say | Science & Tech News

Horses are much smarter than previously thought, researchers have claimed.

Their findings came during a study in which the animals performed better than expected in a complex reward-based game.

When denied treats for not following the rules of the game, researchers found the horses were able to instantly switch strategies to get more rewards.

The scientists from Nottingham Trent University (NTU) said this showed the animals have the ability to think and plan ahead – something previously considered to be beyond their capacity.

Dr Carrie Ijichi, a senior lecturer in equine science at NTU, said: “Horses are not natural geniuses, they are thought of as mediocre, but this study shows they’re not average and are, in fact, more cognitively advanced than we give them credit for.”

The study saw researchers set 20 horses a task consisting of three stages.

In the first stage, the animals touched a piece of card with their nose in order to get a treat.

But things became more complicated when a light was introduced and horses were only allowed a snack if they touched the card while the light was switched off.

The horses kept blindly touching the card, regardless of whether the light was on or off, and were rewarded for correct responses.

In the final stage of the game, a penalty was put in place where touching the card when the “stop” light was on resulted in a 10-second time-out.

But instead of indiscriminately touching the card, the horses were engaging with the rules – only making a move at the right time in order to receive their treat.

Louise Evans, a PhD candidate based in NTU’s School of Animal, Rural and Environmental Sciences, said: “Animals usually need several repetitions of a task to gradually acquire new knowledge, whereas our horses immediately improved when we introduced a cost for errors.

“This suggests that the horses knew all along what the rules of the game were.”

The findings were published in the journal Applied Animal Behaviour Science.

Doctors’ reluctance to discuss anal sex is letting down young women, researchers warn | UK News

Doctors’ reluctance to discuss the possible harms of anal sex is letting down a generation of young women, researchers have warned.

Many doctors are concerned that they may come across as judgemental or homophobic, but by avoiding the topic they may be failing patients who are unaware of the risks, according to a study.

Surgeons Tabitha Gana and Lesley Hunt argue that not discussing it “exposes women to missed diagnoses, futile treatments, and further harm arising from a lack of medical advice”.

Writing in the British Medical Journal, they say healthcare professionals, particularly those in general practice, gastroenterology, and colorectal surgery, “have a duty to acknowledge changes in society around anal sex in young women, and to meet these changes with open, neutral and non-judgemental conversations to ensure that all women have the information they need to make informed choices about sex.”

Data from the National Survey of Sexual Attitudes and Lifestyle shows that participation in heterosexual anal intercourse among 16 to 24 year-olds in Britain rose from 12.5% to 28.5% over the last few decades.

Up to 25% of women with experience of anal sex report they have been pressured into it at least once.

It is also associated with specific health concerns, the surgeons explain.

For example, increased rates of faecal incontinence and anal sphincter injury have been reported in women who have anal intercourse.

Women are also at a higher risk of incontinence than men, due to their different anatomy.

“The pain and bleeding women report after anal sex is indicative of trauma, and risks may be increased if anal sex is coerced,” the authors said.

Effective management of anorectal disorders requires understanding of the underlying risk factors, and good history taking is key, they say.

Yet clinicians may shy away from these discussions, influenced by society’s taboos.

What’s more, NHS patient information on anal sex considers only sexually transmitted diseases, making no mention of anal trauma, incontinence, or the psychological aftermath of the coercion young women report in relation to this activity.

“It may not be just avoidance or stigma that prevents health professionals talking to young women about the risks of anal sex,” the authors said.

“There is genuine concern that the message may be seen as judgemental or even misconstrued as homophobic.

“However, by avoiding these discussions, we may be failing a generation of young women, who are unaware of the risks.”

They added: “With better information, women who want anal sex would be able to protect themselves more effectively from possible harm, and those who agree to anal sex reluctantly to meet society’s expectations or please partners, may feel better empowered to say no.”
