Bill Gates-backed solar startup announces major breakthrough
Posted by Genevieve Klien in categories: solar power, sustainability
Heliogen is a startup that wants to “replace fuels with sunlight.” And the Bill Gates-backed solar startup, which has flown under the radar until today, has made a major green-energy breakthrough for heavy industry. Heliogen “has created the world’s first technology that can commercially replace fuels with carbon-free, ultra-high temperature heat from the sun.”

First detection of sugars in meteorites gives clues to origin of life

An international team has found sugars essential to life in meteorites. The new discovery adds to the growing list of biologically important compounds that have been found in meteorites, supporting the hypothesis that chemical reactions in asteroids—the parent bodies of many meteorites—can make some of life’s ingredients. If correct, meteorite bombardment on ancient Earth may have assisted the origin of life with a supply of life’s building blocks.
The team discovered ribose and other bio-essential sugars including arabinose and xylose in two different meteorites that are rich in carbon, NWA 801 (type CR2) and Murchison (type cm2). Ribose is a crucial component of RNA (ribonucleic acid). In much of modern life, RNA serves as a messenger molecule, copying genetic instructions from the DNA molecule (deoxyribonucleic acid) and delivering them to molecular factories within the cell called ribosomes that read the RNA to build specific proteins needed to carry out life processes.

New Data From First Human Crispr Trials Shows Promising Results

The clinical trials show that two patients have potentially been cured of their genetic illnesses.
Peak phosphorus is a concept to describe the point in time when humanity reaches the maximum global production rate of phosphorus as an industrial and commercial raw material. The term is used in an equivalent way to the better-known term peak oil.[2] The issue was raised as a debate on whether a “peak phosphorus” was imminent or not around 2010, but was largely dismissed after USGS and other organizations increased the world estimates on available phosphorus resources.[3]
Phosphorus is a finite (limited) resource that is widespread in the Earth’s crust and in living organisms but is relatively scarce in concentrated forms, which are not evenly distributed across the Earth. The only cost-effective production method to date is the mining of phosphate rock, but only a few countries have significant reserves of it. The top four are Morocco, China, Algeria and Syria. Estimates for future production vary significantly depending on modelling and assumptions on extractable volumes, but it is inescapable that future production of phosphate rock will be heavily influenced by Morocco in the foreseeable future.[4]
Means of commercial phosphorus production besides mining are few because the phosphorus cycle does not include significant gas-phase transport.[5] The predominant source of phosphorus in modern times is phosphate rock (as opposed to the guano that preceded it). According to some researchers, Earth’s commercial and affordable phosphorus reserves are expected to be depleted in 50–100 years and peak phosphorus to be reached in approximately 2030.[2][6] Others suggest that supplies will last for several hundreds of years.[7] As with the timing of peak oil, the question is not settled, and researchers in different fields regularly publish different estimates of the rock phosphate reserves.[8].
