Why Are We the Only Human Species Left? What happened to others...

Roughly 70,000 years ago, an ice age in Europe caused a massive drought in Africa. Most of the human population died off, with roughly 7,000 individuals surviving along the southern coast of Africa. However, these people built the first permanent dwellings, invented many new tools, and learned to fish.
Once the drought receded, these more technologically advanced humans began spreading out. In a couple of thousand years, they would reach other continents. They likely outcompeted, if not killed, other species of humans.
People of European descent still have a small amount of Neanderthal DNA. Decades ago, there was a report of a skull found in Israel that was half Neanderthal and half Homo sapiens.

Sugar Alcohols Ruined My Health
2 years ago
I didn't notice sugar-alcohols in very many products. I have occasionally bought no-sugar-added mini-pies that contain sugar-alcohols. They give me gas, but as long as I eat them in moderation, I am fine. Too much can have a laxative effect.

Antares Nuclear Mark-0 Microreactor Achieves Criticality at Idaho National Lab
The initiative is intended to help jump-start the US nuclear sector, which largely stagnated after the 1970s due to shifting public opinion, political pressure, and increasingly stringent regulations that prioritized safety above all else. The result was an approval process so complex and costly that it was almost impossible to navigate without going bankrupt. Launched in 2025, the Reactor Pilot Program seeks to fast-track a new generation of reactors by using the DOE's independent safety authorization and oversight process at federal laboratory sites rather than the standard Nuclear Regulatory Commission (NRC) commercial licensing pathway for early-stage technology validation.
