Study links 'stuck' stem cells to hair turning gray (3 minute read)
A study by researchers at NYU Grossman School of Medicine found that certain stem cells in the skin of mice have a unique ability to move between different growth compartments in hair follicles. These cells control hair color by making protein pigments. The study showed that as mice age, these cells increasingly become stuck in the hair follicle stem cell compartment and lose their ability to mature into pigment cells, resulting in a loss of hair color. The same cells are also found in humans.

Ebb Carbon: Ocean Carbon Removal Startup Raises $20 Million Series A (19 minute read)
Ebb Carbon, a startup founded by former Tesla, SolarCity, and Google X employees, has found a way to remove carbon from the atmosphere while making the ocean less acidic. The process involves removing acidity from water and making it slightly alkaline, which triggers a chemical reaction that absorbs carbon dioxide and converts it into bicarbonate. Ebb Carbon's system is designed to be manufactured for scalability. A redacted version of Ebb Carbon's 13-slide pitch deck is available in the article.

GPTCache (GitHub Repo)
GPTCache is a project dedicated to building a semantic cache for storing LLM responses. It aims to lower LLM expenses and decrease response times. GPTCache fetches answers from the cache to eliminate the need to interact with LLM services for similar queries. Besides helping applications scale, GPTCache can also be used by developers to test apps without connecting to an LLM service.

Ask HN: People who were laid off or quit recently, how are you doing? (Hacker News Thread)
This Hacker News thread looks at how people who were laid off or quit recently are doing, whether they have found new work, how the new work compares to their previous jobs, and how their feelings about the industry have changed. Many developers are still looking for work. Workers now feel like they shouldn't do any extra work for companies as it doesn't give workers any benefits. While the current job landscape seems bad, it is comparably better than during the dot com bomb.

When Apple Comes Calling, ‘It’s the Kiss of Death’ (13 minute read)
Apple's long-term plan, when it takes an interest in a company, is to eventually create its own version of the company's product and take it all. It usually starts with Apple approaching a company with discussions about potential partnerships or integration of their technology with Apple products. The talks then end and Apple launches its own similar features. Apple claims that it doesn't steal technology and that it respects the intellectual property of other companies. Apple has attempted to invalidate more patent claims before the Patent Trial and Appeal Board than any other petitioner since 2012.
