We identify "life" with the capability of self-replication plus some other features. In other conditions, for instance on other planets, it could be possible for self-replication to happen in a way different from the RNA/DNA-based one.

I remember stumbling, years ago, on research and papers that studied this kind of possibility. But I'm having a hard time finding the old references or new ones.

Do you have interesting papers and research material to share about this? Thank you!

Use Shopify Apps

If you prefer a more dynamic and interactive size chart:

  1. Explore Shopify App Store: Search for "size chart" or "measurement guide" apps in the Shopify app store.
  2. Install and Configure the App: Select a suitable app and follow the installation instructions. Customize the app settings to match your store's design and preferences.
  3. Add Size Chart Data: Enter the measurements for each size in the app's settings or dashboard.
  4. Integrate with Product Pages: The app will provide a shortcode or integration method to add the size chart to your product pages. Insert the shortcode or follow the provided instructions.
  5. Test and Publish: Ensure the size chart functions correctly and appears as desired on your product pages. Make any necessary adjustments before publishing the changes.

To limit the frequency and severity of droughts, wildfires, flooding, and other adverse consequences of climate change, nearly 200 countries have committed to the Paris Agreement's long-term goal of keeping global warming well below 2 degrees Celsius. According to the latest United Nations Intergovernmental Panel on Climate Change (IPCC) Report, achieving that goal will require both large-scale greenhouse gas (GHG) emissions reduction and removal of GHGs from the atmosphere.

For the first time in the world, we succeeded in synthesizing the room-temperature superconductor (T(C) >= 400K, 127C) working at ambient pressure with a modified lead-apatite (LK-99) structure. The superconductivity of LK-99 is proved with the Critical temperature (T(C)), Zero-resistivity, Critical current (I(C)), Critical magnetic field (H(C)), and the Meissner effect. The superconductivity of LK-99 originates from minute structural distortion by a slight volume shrinkage (0.48 %), not by external factors such as temperature and pressure. The shrinkage is caused by Cu$^{2+}$ substitution of Pb$^{2+}$(2) ions in the insulating network of Pb(2)-phosphate and it generates the stress. It concurrently transfers to Pb(1) of the cylindrical column resulting in distortion of the cylindrical column interface, which creates superconducting quantum wells (SQWs) in the interface. The heat capacity results indicated that the new model is suitable for explaining the superconductivity of LK-99. The unique structure of LK-99 that allows the minute distorted structure to be maintained in the interfaces is the most important factor that LK-99 maintains and exhibits superconductivity at room temperatures and ambient pressure.

Completely Automated, AI-Powered Newsletter: Top Headlines in Politics, Events, Technology, and Business

Hello Everyone!

I'm excited to announce my newest project - an entirely automated Top Headlines Newsletter, powered by GPT-4. Top news that is picked and written entirely by AI is delivered to your inbox every morning at 9 AM PST.

Our system is** fully automated**, taking care of everything from selecting topics to sending the newsletter. This means that if I were to die today, you would still receive a newsletter every morning.

Our newsletter is integrated with our site, and all stories use 2 left, 2 center, and 2 right wing sources (characterized by AllSidesMedia).

I truly think that AI can revolutionize how we consume news, from mitigating polarization, stopping misinformation spread, and minimizing bias. Please let me know your opinions below!
