When it was first discovered in 2004, Apophis was identified as one of the most dangerous asteroids in that there was a risk that it could impact Earth. But that impact assessment changed over the years after astronomers tracked Apophis, also known as asteroid 99,942, and its orbit became better determined, and it became clear that it was on course to miss our planet.
Getting into space is difficult, but it may be that other worlds have even harder times at it than we do, imprisoned by orbital debris, high gravity, or even being quarantined by alien civilizations.

The great mystery of where all the aliens are in our vast Universe contemplates ancient interstellar civilizations building enormous megastructures that rival worlds or even stars in the immensity… and asks why we can’t see these giant alien artifacts.

Working on these next-gen intelligent AIs must be a freaky experience. As Anthropic announces the smartest model ever tested across a range of benchmarks, researchers recall a chilling moment when Claude 3 realized that it was being evaluated.
Anthropic, you may recall, was founded in 2021 by a group of senior OpenAI team members, who broke away because they didn’t agree with OpenAI’s decision to work closely with Microsoft. The company’s Claude and Claude 2 AIs have been competitive with GPT models, but neither Anthropic nor Claude have really broken through into public awareness.
That could well change with Claude 3, since Anthropic now claims to have surpassed GPT-4 and Google’s Gemini 1.0 model on a range of multimodal tests, setting new industry benchmarks “across a wide range of cognitive tasks.”

Star Trek is the most popular and longest running Sci-Fi franchise in American history. Created by Gene Roddenberry, Star Trek follows the various crew of Starfleet in their missions across the galaxy.
This presentation showcases the inspiration behind Star Trek, how the Federation came to be, examines the post-scarcity economy featured in their future Earth society, and explores the philosophies of all of the major alien cultures shown throughout the Star Trek series.

New research shows that nasal drops of neuropeptide Y triggers extinction of fear memories in an animal model of PTSD.
The probe “performed as predicted” during the first of seven close approaches to the sun on its way to Apophis, NASA said.
Here’s my latest Opinion piece just out for Newsweek. Check it out! Lifeboat Foundation mentioned.
We need to remember that universal distress we all had when the world started to shut down in March 2020: when not enough ventilators and hospital beds could be found; when food shelves and supplies were scarce; when no COVID-19 vaccines existed. We need to remember because COVID is just one of many different existential risks that can appear out of nowhere, and halt our lives as we know it.
Naturally, I’m glad that the world has carried on with its head high after the pandemic, but I’m also worried that more people didn’t take to heart a longer-term philosophical view that human and earthly life is highly tentative. The best, most practical way to protect ourselves from more existential risks is to try to protect ourselves ahead of time.
That means creating vaccines for diseases even when no dire need is imminent. That means trying to continue to denuclearize the military regardless of social conflicts. That means granting astronomers billions of dollars to scan the skies for planet-killer asteroids. That means spending time to build safeguards into AI, and keeping it far from military munitions.
If we don’t take these steps now, either via government or private action, it could be far too late when a global threat emerges. We must treat existential risk as the threat it is: a human species and planet killer—the potential end of everything we know.
