Scientists discovered that non-brain cells in the body can learn and form memories, opening new pathways for understanding memory and treating memory-related afflictions. The study found that non-brain cells can detect patterns and retain information better when studied in spaced intervals, similar to the brain's massed-spaced effect.

To quickly print debug text without a font atlas texture, a technique uses a GLSL fragment shader to map a fragment's xy position to a bit in a stored font bitmap, drawing in foreground or background color based on the bit's state. This technique uses instanced drawing with two attribute streams, one for quad drawing and one for per-instance data including position offset and text to print, ...

They also discuss the limitations and potential misuse of LLMs, as well as the benefits of using them as a tool for augmenting human capabilities rather than replacing them.

NASA's Crew-8 astronauts were hospitalized after splashing down on Earth due to an unidentified medical issue. NASA is maintaining medical privacy and will release more information in the future, citing the complexity of space flight and its effects on the human body.

SQLite uses a write lock at the DB level, allowing only one connection to write at a time. This can be mitigated with immediate transactions that queue queries to retry acquiring the write lock.

The animation draws Voronoi cells around moving points on a Moore curve using a shader and Inigo Quilez's technique. The points follow a looping Hilbert curve with a "replacement technique" and a move speed factor controlling the pause duration.

The author argues that in the field of biology, companies that focus on ambitious and groundbreaking research often overshadow those that focus on more mundane but impactful tasks, such as developing better contract research organizations (CROs) or improving lab automation. The author believes that more attention should be given to "boring" biotech companies that prioritize practicality and ...
