Made my Asuna cosplay back in 2019. Was supposed to be part of a group but I ended up the only one finishing my cosplay so that sadly never happened 😭 still happy I made it nonetheless as it taught me alot of things 💙

[A hydrothermal system on #Mars] In the rocks bounding the Jezero impact crater, the #Pereverance rover's instrument array has detected the presence of #silica in various forms: opal, chalcedony and #quartz. Evidence of water-rock interaction dating back to the very beginning of the Red Planet's history ....

Knowing that siliceous rocks - opal in particular - have a remarkable ability to preserve traces of #life, all that remains is to sample these rocks and bring them back to Earth for further exobiological analysis.

When we think of #nutrients that limit #algae growth, it is usually nitrogen or phosphorus, which is absolutely true, but occasionally, other factors become important. One is hydrated silica dioxide, which is necessary for #diatoms to produce their glass "frustule" shells. In both lakes and oceans, #silica can be drawn down to the point it prevents reproduction. So, in some locations "dissolved sand" can actually limit algal growth. #Science

Scientists have stored a copy of humanity's genetic blueprint inside a near-indestructible "5D memory crystal" — a new data storage format that could keep the information safe for billions of years, or even potentially to the end of time.

The researchers believe the DNA time capsule could be used to revive our species long after we have gone extinct.

Environmental Impacts of #Geothermal Energy

Published Mar 5, 2013
Union of Concerned Scientists

"The most widely developed type of geothermal power plant (known as #hydrothermal plants) are located near #geologic#HotSpots” where hot molten rock is close to the earth’s crust and produces hot water. In other regions enhanced geothermal systems (or hot dry rock geothermal), which involve drilling into Earth’s surface to reach deeper geothermal resources, can allow broader access to geothermal energy."

[...]

"Some geothermal plants also produce small amounts of #mercury emissions, which must be mitigated using mercury filter technology. Scrubbers can reduce air emissions, but they produce a watery #sludge composed of the captured materials, including #sulfur, #vanadium, #silica compounds, chlorides, #arsenic, mercury, #nickel, and other heavy metals. This #ToxicSludge often must be disposed of at hazardous waste sites."

[...]

"Land #subsidence, a phenomenon in which the land surface sinks, is sometimes caused by the removal of water from geothermal reservoirs. Most geothermal facilities address this risk by re-injecting wastewater back into geothermal reservoirs after the water’s heat has been captured.

"Hydrothermal plants are sited on geological “hot spots," which tend to have higher levels of #earthquake risk. There is evidence that hydrothermal plants can lead to an even greater earthquake frequency. Enhanced geothermal systems (hot dry rock) can also increase the risk of small earthquakes. In this process, water is pumped at high pressures to fracture underground hot rock reservoirs similar to technology used in natural gas hydraulic #fracturing. (See How Natural Gas Works for more information.) Earthquake risk associated with enhanced geothermal systems can be minimized by siting plants an appropriate distance away from major fault lines. When a geothermal system is sited near a heavily populated area, constant monitoring and transparent communication with local communities is also necessary."
