Free and open software have transformed the tech industry. But we still have a lot to work out to make them healthy, equitable enterprises.
Scientists studying learning in mice have inadvertently encountered ‘zombie neurons’ in the brain – not flesh-eating, virus-spreading monsters, but cells that stop interacting normally even though they’re functionally alive. What’s more, they shed new light on learning processes in the brain.
A team from Portugal discovered the cells as part of an investigation into how a part of the brain called the cerebellum learns from the environment around us.
The cerebellum processes sensory information related to motor movements. It helps us walk down a crowded street, or pick up a drink without spilling it, and it’s also important for learning: so if we bump into something, we know how to refine our movement to avoid it next time. Exactly how that learning happens was the subject of this new study.
Rational and scientific use of hyperspectral imaging involves the selection of appropriate imaging hardware and data analysis software. Sun et al. describe applications of hyperspectral imaging in food quality inspection and provide guidance for non-specialist researchers aiming to implement this technology.
A newly developed AI method can calculate a fundamental problem in quantum chemistry: Schrödinger’s Equation. The technique could calculate the ground state of the Schrödinger equation in quantum chemistry.
Predicting molecules’ chemical and physical properties by relying on their atoms’ arrangement in space is the main goal of quantum chemistry. This can be achieved by solving the Schrödinger equation, but in practice, this is extremely difficult.
Despite their ancient ages, some stars orbiting the Milky Way’s central supermassive black hole appear deceptively youthful. But unlike humans, who might appear rejuvenated from a fresh round of collagen injections, these stars look young for a much darker reason.

Experts are concerned about the way our planet is rotating due to climate change. For years, scientists have been concerned about the impacts of global warming.
Now, new research has revealed a change in the Earth’s spin due to the melting of the ice poles.

Study: Dr ChatGPT tell me what I want to hear: How different prompts impact health answer correctness
As AI becomes increasingly integral to our daily lives, its ability to provide accurate and reliable information, particularly in sensitive areas such as health, is under intense scrutiny. The study conducted by CSIRO and The University of Queensland researchers brings to light the nuanced ways in which the formulation of prompts influences ChatGPT’s responses. In the realm of health information seeking, where the accuracy of the information can have profound implications, the findings of this study are especially pertinent.
Using the Text Retrieval Conference (TREC) Misinformation dataset, the study precisely evaluated ChatGPT’s performance across different prompting conditions. This analysis revealed that ChatGPT could deliver highly accurate health advice, with an effectiveness rate of 80% when provided with questions alone. However, this effectiveness is significantly compromised by biases introduced through the phrasing of questions and the inclusion of additional information in the prompts.
