Stoicism and Longevity Research

Posted by in category: life extension

Of the three great Stoics, Seneca always interested me the least. A playwright and professional philosopher, he seemed unlikely to be acquainted with the more mundane forms of suffering that beset humanity. This made him seem unfit to propound upon a philosophy concerned with right conduct under challenging circumstances.

Marcus Aurelius, ruler of an enormous empire, spent most of his reign embroiled in wars he had no desire to fight. Epictetus, a Greek who endured the hardships of slavery, also embodied the Stoic ideal. Cries of “ad hominem!” aside, it is hard to dispute that our experiences shape our outlooks on living. Biographical criticisms can be flimsy, but the central argument in De Brevitate Vitae — an otherwise inspirational classic — was exceptionally naive for the 1st century.

Although Seneca understood intrigue and exile firsthand, he was not privy to the time-sapping vicissitudes of householding or holding down a job.

Multimodality and Large Multimodal Models (LMMs)

Posted by in categories: media & arts, robotics/AI

For a long time, each ML model operated in one data mode – text (translation, language modeling), image (object detection, image classification), or audio (speech recognition).

However, natural intelligence is not limited to just a single modality. Humans can read and write text. We can see images and watch videos. We listen to music to relax and watch out for strange noises to detect danger. Being able to work with multimodal data is essential for us or any AI to operate in the real world.

OpenAI noted in their GPT-4V system card that “incorporating additional modalities (such as image inputs) into LLMs is viewed by some as a key frontier in AI research and development.”

Electronic waste — more recycling needs to be encouraged

Posted by in categories: materials, sustainability

New research conducted by the not-for-profit organisation, Material Focus, has found that half a billion small, cheap electrical everyday items, such as headphones or handheld fans, found their way into landfill in the UK last year.

$9.5 bn of key metals in overlooked electronic waste: UN

Posted by in categories: sustainability, transportation

Consumers discard or possess disused electronic goods containing raw materials critical for the green energy transition and worth almost $10 billion every year, the United Nations said on Thursday.

Toys, cables, , tools, electric toothbrushes, shavers, headphones and other domestic gadgets contain metals like lithium, gold, silver and copper.

Demand is expected to soar for these materials due to their crucial role in rapidly growing green industries such as electric vehicle battery production.

Raytheon to build revolutionary rotating detonation engine for DARPA

Posted by in categories: energy, military

DARPA has contracted Raytheon to develop a practical version of a revolutionary air-breathing rotating detonation engine called Gambit, which would have no moving parts and could lead to lighter missiles with longer ranges at lower cost.

Gas turbines are remarkable power plants that have made possible modern air travel and many weapon systems, but they suffer from a number of disadvantages. They are complex machines that are heavy, have many moving parts that are costly to assemble and maintain, and they require exotic materials and special processing to handle the tremendous temperatures they operate at.

It’s bad enough when such an engine is installed in an aircraft, but when it’s part of a throwaway weapon like a cruise missile, this not only limits the payload, it runs into some serious money.

Scientists unlock biological secrets of the aging process

Posted by in categories: biological, life extension

How we grow old gracefully—and whether we can do anything to slow down the process—has long been a fascination of humanity. However, despite continued research the answer to how we can successfully combat aging still remains elusive.
