New $150M facility will fire 7-petawatt lasers to (hopefully) achieve nuclear fusion

Forward-looking: Fusion energy is often regarded as the holy grail of power generation because it harnesses the same atomic process that powers the sun. The concept involves forcing atomic nuclei to fuse together, unleashing immense energy. If scientists can crack the code using lasers, it could lead to a virtually limitless supply of safe, sustainable energy without any carbon emissions.

Scientists use explosive X-rays to test viability of nuking incoming asteroids

Spoiler alert: It works but testing on an actual asteroid might be needed
Why it matters: The concept of launching nukes into space to knock asteroids off course or destroy them completely may not sound foreign thanks to numerous sci-fi films popularizing it. But the lack of atmosphere in space nerfs nukes' power considerably, so the idea isn't so easy to pull off. Now, researchers at Sandia National Labs have come up with a new way to compensate for this shortcoming.

US seeks assurance from China and Russia that AI will never control their nuclear weapons

What could possibly go wrong with giving AI control of nukes?
What just happened? If you think the prospect of artificial intelligence controlling fighter jets, drones, and machine gun turrets is concerning, think about the potential ramifications of AI making decisions on the deployment of nuclear weapons. The US is one of the countries that has declared control over nukes will also rest in human hands, and it wants China and Russia to make the same promise.

In nuclear fusion milestone, Japan unveils the world's largest reactor

The system is an important step forward to harnessing fusion as a clean energy source
Forward-looking: Fusion differs from fission, which is used in nuclear power plants, and it is based on the same principle that powers the Sun and stars as the hydrogen nuclei fuses into helium, releasing light and heat. Also, unlike nuclear power, fusion is intrinsically safe in that the reaction stops when the fuel supply or power source is shut down. Nor does it generate high-level long-lived radioactive waste.

Experts and CEOs warn of extinction risk posed by AI, compare dangers to nuclear war

"Mitigating the risk of extinction from AI should be a global priority"
What just happened? It's a case of another day, another warning about the possibility of AI causing the extinction of the human race. On this occasion, it's been compared it to the risks posed by nuclear war and pandemics. The statement comes from experts in the field and those behind these systems, including OpenAI CEO Sam Altman.
