How one brain circuit encodes memories of both places and events
Nearly 50 years ago, neuroscientists discovered cells within the brain’s hippocampus that store memories of specific locations. These cells also play an important role in storing memories of events, known as episodic memories. While the mechanism of how place cells encode spatial memory has been well-characterized, it has remained a puzzle how they encode episodic memories.A new model developed by MIT researchers explains how those place cells can be recruited to form episodic memories, even whe
Scientists achieve direct experimental realization of dual-type entangling gates
To develop scalable and reliable quantum computers, engineers and physicists will need to devise effective strategies to mitigate errors in their quantum systems without adding complex additional components. A promising strategy to reduce errors entails the use of so-called dual-type qubits.
Air pollution and brain damage: what the science says
<p>Nature, Published online: 14 January 2025; <a href="https://www.nature.com/articles/d41586-025-00053-y">doi:10.1038/d41586-025-00053-y</a></p>Epidemiological studies have linked dirty air to dementia and other brain disorders. Now researchers are trying to determine how pollutants do their damage, and how much harm they cause.
