Hippos spew ‘tornado poo’ when they hear the voice of a hippo stranger

It might sound gross, but this knowledge could help with hippo conservation efforts.

When you hear a stranger’s voice, hopefully you don’t react by releasing «tornado poo.» Scientists have learned that hippopotamuses, however, have a tendency to defecate intensely upon hearing an unfamiliar hippo’s call. That might sound melodramatic, but it’s actually a way hippos mark their space. They’re known to be aggressive and males sometimes in engage in battle.

A study published in the journal Current Biology on Monday delves into the secret social lives of hippos. News portal Science Media Exchange, which published the Cell Press release on the study, seems to be the one that came up with the evocative «tornado poo» description. That phrase doesn’t appear in the paper, which prefers «dung spraying.»

The research took place in the Maputo Special Reserve in Mozambique. The reserve is home to multiple groups of hippos residing in different lakes, giving researchers the chance to record calls (hippos sound a loud «wheeze honk»)from animals that lived near each other, and from ones that were total strangers.

The researchers played the calls for the animals and monitored the reactions. «We found that the vocalizations of a stranger individual induced a stronger behavioral response than those produced by individuals from either the same or a neighboring group,» said co-author Nicolas Mathevon of University of Saint-Etienne, France. Hippos responded to the recordings by vocalizing back, approaching or spraying dung, or sometimes a combination of those behaviors. The hippos were more likely to unleash dung when hearing a stranger’s call.

The study could help when hippos need to be moved as part of efforts to conserve the species. «Before relocating a group of hippos to a new location, one precaution might be to broadcast their voices from a loudspeaker to the groups already present so that they become accustomed to them and their aggression gradually decreases,» Mathevon suggests. The same could be done for the hippos being moved, essentially a get-to-know-you effort on both sides.

Hippos are listed as vulnerable on the IUCN Red List of Threatened Species, which catalogs the conservation status of animals and plants. The researchers hope to learn more about how hippos communicate through future studies. They’re expressive animals, whether they’re using their mouths or a very different part of their anatomy.

Apple’s New Smart Home Display Delayed Until Fall Over Siri Issues

It has been nearly a year and a half since the company announced the AI-powered product.

Your home could get smarter with Apple’s Siri, but it will have to wait a few more months. Bloomberg reported the iPad-shaped AI home hub won’t be ready until September, several months after the company was hoping to launch it this spring. Apple engineers first need to complete work on a new and improved Siri assistant for the home device, code-named J490, according to Bloomberg.

Apple was hoping to release J490 this month, along with a slew of other new devices, including the iPhone 17e, MacBook Neo, MacBook Air M5, new Pro models, and iPad Air M4. Apple first teased the smart home display in November 2024.

A representative for Apple did not immediately respond to a request for comment.

Siri is Apple’s virtual assistant that uses voice recognition and AI to fulfill a variety of tasks and commands, along with intriguing uses. You might use Siri to find your iPhone — «Hey Siri, where are you?» — or to hear the weather forecast — «Siri, what will the weather be today?» Siri is available on iPhones, MacBooks and iPads. It was launched in 2011 as a feature of the iPhone 4S.

As CNET reported last month, Apple engineers have struggled to push the upgraded Siri assistant out the door. It isn’t fast enough, gets confused by complex commands and doesn’t interact well with other Apple AI models. The company is also wrestling with how much personal data to access to inform the AI, and the new Siri is not yet able to complete in-app tasks, such as finding a photo and posting it to socials, all with one command.

It has been nearly two years since Apple announced that it would give Siri a major upgrade. In the meantime, competitors like Alexa Plus and Gemini for Home have entered the marketplace.

Tech tester Jon Rettinger, whose YouTube channel has 1.66 million subscribers, says the repeated delays in upgrading Siri can «erode» confidence in Apple’s ability to keep up in the AI race.

«Apple as a whole is still one of the strongest companies on the planet. But their AI play is clearly the weakest link in an otherwise very strong chain,» Rettinger told CNET.

Rettinger said he has had issues getting Siri to complete basic commands, such as setting two alarms at the same time, and that it’s a bit of «a mess» right now.

«Having said that, the iPhone has such massive market penetration that I’m not sure it will actually matter in the end. Which is kind of wild when you think about it,» Rettinger said.

Facial recognition for residents

The hardware for the forthcoming smart home display has already been finished. It resembles an iPad and can be either attached to a wall or rest on a half-domed-shaped base, the Bloomberg report said.

The device will be equipped with facial recognition, so when residents walk up to it, they will be shown personalized data such as music preferences, news headlines, appointments, reminders, tasks and so on.

The screen interface will include a bunch of circular app icons, similar to the display on an Apple Watch. The Bloomberg report said the smart home display will be the first of several home devices by Apple. Future products include a tabletop robotic limb with a 9-inch screen, a smart security camera and a Face ID-enabled smart doorbell.
