The Global Carbon Project reported that world CO2 emissions reached 37 billion tons per year in 2019. This was an increase from the 36.6 billion tons emission estimate for 2018. This was a 0.6% increase from 2018. There was 2.1 …

Researchers injected D-ESCs (embryonic stem cells) into porcine blastocysts (pig pre-embyros) to obtain neonatal interspecies chimeras. The D-ESCs differentiated into all three germ layers in the pig fetuses, consistent with a previous study reporting human/pig chimeras. The human/pig fetuses survived …

A study analyzed the nuclear power capacity needed in China by 2050 to realize the 1.5 °C target, as well as the feasibility, necessary measures, and difficulty. China generated 6990 terawatt-hours of electricity in 2018 and is generating 3.1% more …

Commonwealth Fusion Systems (CFS), a startup commercializing fusion energy, has raised $115 million and closed its Series A round. New participants in the round include Future Ventures, Khosla Ventures, Lowercase Capital, Moore Strategic Ventures, Safar Partners, Schooner Capital, and Starlight …

2020 starts in 26 days. 2020 is a milestone year and those are years when people love to make long-range predictions. I, Brian Wang of Nextbigfuture, have been tracking global developments for over 40 years. I will make some long-range …

A NASA NIAC study is developing the technology to get within 0.5 solar radii of the sun. The goal is to scatter 99.9% of the solar radiation. A solar radii is 700,000 kilometers. They want to get to 0 to …

Rigidized polymers appear to be a feasible technology to create space telescopes larger than kilometer sizes. It should be possible to make 50 meter space telescope elements in 1000 kilometer baseline space telescope arrays. The Event Horizon Telescope at 1.3 …
