Summary: A new study reveals how AI-driven deep learning models can decode the genetic regulatory switches that define brain cell types across species. By analyzing human, mouse, and chicken brains, researchers found that some brain cell types remain highly conserved over 320 million years, while others have evolved uniquely.

This regulatory code not only sheds light on brain evolution but also provides new tools for studying gene regulation in health and disease. The findings highlight how AI can identify preserved and divergent genetic instructions controlling brain function across species.

The study also has implications for understanding neurological disorders by linking genetic variants to cognitive traits. Researchers are now expanding their models to study the brains of various animals and human disease states like Parkinson’s.

Dream, a company focused on artificial intelligence (AI)-powered cybersecurity for nations and critical infrastructure, raised $100 million in a Series B funding round to expand into additional markets in which cyber threats pose challenges to national security.

The round valued Dream at $1.1 billion, the company said in a Monday (Feb. 17) press release.

Cyberattacks on critical infrastructure are becoming more common and more sophisticated, Sebastian Kurz, co-founder and president of Dream, and former prime minister of Austria, said in the release.

Science and Technology: 💻 A recent study conducted by researchers at Fudan University in China suggests that artificial intelligence (AI) systems may have taken a worrying step: self-replication without human assistance.

S Llama31-70B-Instruct and Alibaba “Successful self-replication without human assistance is the essential step for AI to outperform[humans], and is an early signal for rogue AIs,” the authors wrote in the paper. They added that understanding the risks associated with next-generation artificial intelligence, or “frontier AI,” is key to anticipating undesirable scenarios. The scientists investigated two specific scenarios: “shutdown avoidance” and “replication chain.” In the first case, an AI model was instructed to detect signs that it was about to shut down and then create a copy of itself before that happened. In the second scenario, the AI was told to replicate itself and then program the replica to do the same, starting a possible infinite cycle of copying.

To conduct these tests, the team created a “scaffolding agent,” or a set of system tools and instructions that allow the AI to interact with the operating system. They said there was no direct human interference in the process. At various times, when obstacles such as software conflicts or missing files arose, AIs found ways to work around them, including terminating conflicting processes and restarting the system.
