From text-generating ChatGPT to voice-activated Siri, artificial intelligence-powered tools are designed to aid our everyday life -- as long as you speak a language they support. These technologies are out of reach for billions of people who don't use English, French, Spanish or other mainstream languages, but researchers in Africa are looking to change that. Scientists now draw a roadmap to develop better AI-driven tools for African languages.

Plants orient their organs in response to the gravity vector, with roots growing towards gravity and shoots growing in the opposite direction. The movement of statoliths responding to the inclination relative to the gravity vector is employed for gravity sensing in both plants and animals. However, in plants, the statolith takes the form of a high-density organelle, known as an amyloplast, which settles toward gravity within the gravity sensing cell. Despite the significance of this gravity sensing mechanism, the exact process behind it has eluded scientists for over a century.

Rapid alkalinization factors (RALFs) are required for pollen tube germination and elongation, an essential process in plant fertilization. But their role in monocot plants remains unexplored. Scientists have now identified OsRALF17 and OsRALF19 in rice and determined their functions in pollen tube germination and growth. This study provides novel insights into the role of RALFs in rice fertilization, paving the way for enhanced grain yield.

Developing new materials requires significant time and labor, but some chemists are now hopeful that artificial intelligence (AI) could one day shoulder much of this burden. In a new study, a team prompted a popular AI model, ChatGPT, to perform one particularly time-consuming task: searching scientific literature. With that data, they built a second tool, a model to predict experimental results.

A 390-million-year-old moss called Takakia lives in some of Earth's most remote places, including the icy cliffs of the Tibetan Plateau. In a decade-long project, a team of scientists climbed some of the tallest peaks in the world to find Takakia, sequence its DNA for the first time, and study how climate change is impacting the moss. Their results show that Takakia is one of the fastest evolving species ever studied -- but it likely isn't evolving fast enough to survive climate change.

New research shows that electrical stimuli passed between neighboring electrodes can also affect non-neighboring electrodes. Known as non-locality, this discovery is a crucial milestone toward creating brain-like computers with minimal energy requirements.

Researchers have developed a new explainable artificial intelligence (AI) model to reduce bias and enhance trust and accuracy in machine learning-generated decision-making and knowledge organization.

Researchers have unveiled an artificial intelligence-based model for computational imaging and microscopy without training with experimental objects or real data. The team introduced a self-supervised AI model nicknamed GedankenNet that learns from physics laws and thought experiments. Informed only by the laws of physics that universally govern the propagation of electromagnetic waves in space, the researchers taught their AI model to reconstruct microscopic images using only random artificial holograms -- synthesized solely from 'imagination' without relying on any real-world experiments, actual sample resemblances or real data.

As we start to edge out of winter, improving our diet and boosting our exercise start to appear on our agenda. But, when it comes to encouraging a healthier lifestyle, it may surprise you that artificial intelligence could be your best friend.

The research team at The University of Texas at Austin created a noninvasive electroencephalogram (EEG) sensor that they installed in a Meta VR headset that can be worn comfortably for long periods. The EEG measures the brain's electrical activity during the immersive VR interactions.

Researchers have found that robots can have a 'U-shaped' effect on profits: causing profit margins to fall at first, before eventually rising again. The researchers studied industry data from the UK and 24 other European countries between 1995 and 2017, and found that at low levels of adoption, robots have a negative effect on profit margins. But at higher levels of adoption, robots can help increase profits.

Northern muriquis, which live in the Atlantic forest of Brazil, are one of the most endangered species of monkey in the world. To better understand what goes on in the mating lives of muriquis, researchers turned to the monkeys' poop to help gain insight into how the primates choose their mates.

Researchers looked at the effects of declawing on larger cat species and found that declawing disproportionately impacts their muscular capabilities as compared to their smaller brethren.

The artificial intelligence language model GPT-3 performed as well as college students in solving certain logic problems like those that appear on standardized tests. The researchers who conducted the experiment write that the results prompt the question of whether the technology is mimicking human reasoning or using a new type of cognitive process. Solving that question would require access to the software that underpins GPT-3 and other AI software.
