Just like the gut, the skin and the mouth, the eye also has a collection of microbes that keep it healthy. Understanding the eye microbiome may lead to new probiotic therapies.
Researchers from Washington University School of Medicine in St. Louis have discovered a way to delay aging in mice with a protein that is abundant in the blood of young mice but declines with age.
eNAMPT and the NAD salvage pathway
That protein is extracellular nicotinamide phosphoribosyltransferase (eNAMPT), and it plays a key role in the process that cells use to create nicotinamide adenine dinucleotide (NAD), a crucial component that they need for energy production. NAD is a coenzyme found in all living cells. It is a dinucleotide, which means that it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine base, and the other contains nicotinamide.
Artificial Intelligence (AI) is an emerging field of computer programming that is already changing the way we interact online and in real life, but the term ‘intelligence’ has been poorly defined. Rather than focusing on smarts, researchers should be looking at the implications and viability of artificial consciousness as that’s the real driver behind intelligent decisions.
Consciousness rather than intelligence should be the true measure of AI. At the moment, despite all our efforts, there’s none.
Significant advances have been made in the field of AI over the past decade, in particular with machine learning, but artificial intelligence itself remains elusive. Instead, what we have is artificial serfs—computers with the ability to trawl through billions of interactions and arrive at conclusions, exposing trends and providing recommendations, but they’re blind to any real intelligence. What’s needed is artificial awareness.
Elon Musk has called AI the “biggest existential threat” facing humanity and likened it to “summoning a demon,”[1] while Stephen Hawking thought it would be the “worst event” in the history of civilization and could “end with humans being replaced.”[2] Although this sounds alarmist, like something from a science fiction movie, both concerns are founded on a well-established scientific premise found in biology—the principle of competitive exclusion.[3]
