If tiny lab-grown 'brains' became conscious, would it still be OK to experiment on them?

Recent advancements in lab-grown brain tissue have sparked a debate among neuroscientists about the potential for these tiny 'brains' to develop consciousness and experience pain. While current models are too simplistic for such experiences, the rapid pace of innovation raises ethical questions that society must address. As we push the boundaries of science, it's crucial to consider the implications of creating entities that could possess awareness, making this a timely discussion in the field of neuroscience.

This week in science news, we explore the discovery of the world's oldest mummy and an intriguing ant species that mates with clones of a distant relative. These findings not only shed light on ancient civilizations but also challenge our understanding of reproduction in the animal kingdom. Such discoveries are essential as they expand our knowledge of biodiversity and evolutionary processes, making them significant for both researchers and enthusiasts alike.

A significant milestone has been reached as sixty states have ratified a global treaty aimed at protecting the oceans, which will officially come into force in January. This treaty is crucial for marine conservation and reflects a growing international commitment to safeguarding our oceans, highlighting the importance of collaborative efforts in addressing environmental challenges.

The CDC's Advisory Committee on Immunization Practices has recently updated its recommendations regarding eligibility for this year's COVID-19 vaccines. This is important as it helps clarify who can receive the updated vaccines, ensuring that those most at risk are protected. Staying informed about these changes is crucial for public health and safety.

The recent decision by Kennedy's vaccine panel to limit access to COVID shots has raised concerns among public health advocates. This move could hinder efforts to achieve widespread vaccination, which is crucial for controlling the pandemic. As COVID-19 continues to pose a threat, limiting access to vaccines may lead to increased infections and complications, making this decision significant for public health.

A recent survey reveals that a quarter of UK university physics departments are at risk of closure due to funding pressures, with four out of five departments already making staff cuts. This alarming trend raises concerns about the future of physics education in the UK and its implications for the country's leadership in scientific research and innovation. The Institute of Physics highlights the urgency of addressing these challenges to ensure the sustainability of physics as a vital field of study.

Exciting news for space enthusiasts! NASA's VIPER moon rover, which was thought to be shelved, is set to be launched by Blue Origin in 2027. This mission aims to hunt for ice on the moon, which could be crucial for future lunar exploration and even for potential human colonization. The collaboration between NASA and Jeff Bezos' company highlights a significant step forward in our quest to understand the moon's resources and pave the way for deeper space missions.
