Robot taught table etiquette can explain why it won t follow the rules

frederik enneman / Alamy We use what is known as inner speech, where we talk to ourselves, to evaluate situations and make more-informed decisions. Now, a robot has been trained to speak aloud its inner decision-making process, giving us a view of how it prioritises competing demands. Arianna Pipitone and Antonio Chella at the University of Palermo, Italy, programmed a humanoid robot named Pepper, made by SoftBank Robotics in Japan, with software that models human cognitive processes, as well as a text-to-speech processor. This allowed Pepper to voice its decision-making process while completing a task. “With inner speech, we can better understand what the robot wants to do and what its plan is,” says Chella.

Alaskan forests may store more carbon after being burned by wildfire

Design Pics Inc/Alamy As the boreal forests of Alaska recover from wildfires, they may shift from containing mostly coniferous trees to a deciduous-coniferous mix – and this change could ultimately offset some of the carbon emitted during the fires. Climate change is making wildfires more frequent and intense in certain parts of the world, such as the boreal forests of the Arctic. These forests typically act as carbon sinks, but if fires burn deep into their soil, they could begin to release more carbon into the atmosphere than they store through new wood growth, accelerating the effects of climate change.

Female monkeys call to males when they see a predator approaching

C.Kolopp/WCS When faced with a predator, female putty-nosed monkeys will call males to help protect them from the threat. Putty-nosed monkeys ( Cercopithecus nictitans) live in the forests of West Africa in groups of one male with multiple females and their offspring. The male will tend to roam further from the group and leave females to forage for themselves, but the females and lone male will alert each other when predators are nearby. Advertisement Communication in this species differs based on sex. Females produce a single “chirp” to alert others when any form of predator is nearby, while the lone males will use different calls based on the type of predator spotted: “pyow” calls for those on the ground, like leopards, and “hack” calls for predatory eagles.

Most alien civilisations risk fuelling global warming on their planets

NASA, ESA, M. Kornmesser Most planets inhabited by advanced civilisations would be likely to face catastrophic climate change as a result of burning fuel, researchers have found. Human activity has had a geological impact on Earth, putting it into a new epoch known as the Anthropocene. Adam Frank at the University of Rochester, New York, and his colleagues wanted to know if the same thing might happen on other Earth-like planets. The researchers began with the assumption that “exocivilisations” would arise on planets with initial carbon dioxide levels … Continue reading Subscribe now for unlimited access App + Web
