Researchers teach LLMs to solve complex planning challenges https://lifeboat.com/blog/2025/04/researchers-teach-llms-to-solve-complex-planning-challenges https://lifeboat.com/blog/2025/04/researchers-teach-llms-to-solve-complex-planning-challenges#respond Thu, 03 Apr 2025 02:11:13 +0000 https://lifeboat.com/blog/2025/04/researchers-teach-llms-to-solve-complex-planning-challenges

A new large language model framework teaches LLMs to use an optimization solving algorithm to resolve complex, multistep planning tasks. With the LLMFP framework, someone can input a natural language description of their problem and receive a plan to reach their desired goal.

30 Years Younger & Telomere Extension? Could Short Chains of Amino Acids Revolutionize Anti-aging? https://lifeboat.com/blog/2025/04/30-years-younger-telomere-extension-could-short-chains-of-amino-acids-revolutionize-anti-aging https://lifeboat.com/blog/2025/04/30-years-younger-telomere-extension-could-short-chains-of-amino-acids-revolutionize-anti-aging#respond Thu, 03 Apr 2025 02:03:46 +0000 https://lifeboat.com/blog/2025/04/30-years-younger-telomere-extension-could-short-chains-of-amino-acids-revolutionize-anti-aging

Could Short Chains of Amino Acids Revolutionize Anti-aging? We explore the exciting potential of peptide therapy to address key hallmarks of aging, including biological age and telomere length. This video delves into the science behind peptides and examines early clinical findings that suggest significant possibilities for age reversal.

What you’ll learn:
• Key peptides being studied for anti-aging (Epitalon, GHK-Cu, etc.).
• A look at clinical studies and patient data.
• The future of peptide therapy in longevity research.

Cancer cells ‘hacked’ to expose themselves to immune attack https://lifeboat.com/blog/2025/04/cancer-cells-hacked-to-expose-themselves-to-immune-attack https://lifeboat.com/blog/2025/04/cancer-cells-hacked-to-expose-themselves-to-immune-attack#respond Wed, 02 Apr 2025 22:06:28 +0000 https://lifeboat.com/blog/2025/04/cancer-cells-hacked-to-expose-themselves-to-immune-attack

When your social media account starts spewing out nonsensical or threatening status updates, it’s safe to assume that it has been hacked and must be shut down.

The cells in our body also update their “status” by presenting to their environment small proteins that are constantly being produced inside the cell. Our monitors these statuses and destroys cells that produce unusual proteins. A classic example of this is when a cell is infected by a virus and presents parts of the viral proteins on its surface, which allows the immune system to recognize them and destroy the cell.

In contrast, cancer cells often evade detection by displaying very few suspicious proteins that the immune system can identify and target. A new approach to cancer treatment, developed by researchers from Prof. Yardena Samuels’s lab at the Weizmann Institute of Science, increases the number of the immune system’s targets by disrupting production in .
