China’s Ambitious Plan to Build the World’s Biggest Supergrid (9 minute read)
China’s massive consumption of electricity over a large area presents unique problems in power transporting. 22 ultra-high-voltage (UHV) power grids have been built in the last decade, which power more than 30,000 km of UHV lines. A single line between Gansu-Hunan moved about 24 terawatt-hours between 2017 and 2019. China produces clean energy in its north-west region but its highest power consumption is in its south-east region. While linking its power grids together to create a supergrid may solve one of the many power issues in the country, it may also make the country more vulnerable to cascading blackouts. Being a world’s first, engineers are breaking new ground and a full understanding of the problems relating to building such a supergrid is still being developed.
China’s CRISPR twins might have had their brains inadvertently enhanced (3 minute read)
The removal of the CCR5 gene has been shown to have an effect on memory, cognition, and brain recovery. A lack of the CCR5 gene also protects against HIV, as the virus requires the gene in order to attach to a host. A scientist in China used CRISPR to delete the CCR5 gene in a pair of twin girls while they were embryos. It was claimed that the procedure was done in order to make the girls immune to HIV. The scientist is under investigation by China, but there is a lack of evidence that the procedure was done with the intent of enhancing the cognition of the twins.

simdjson : Parsing gigabytes of JSON per second (GitHub Repo)
JSON documents are everywhere on the internet, and this C++ library is able to parse gigabytes of JSON data in seconds. simdjson uses fewer instructions compared to RapidJSON and sajson, while still fully validating the document. The parser creates an immutable DOM file which can later be accessed. There are instructions on installation and use, as well as performance comparisons with other JSON parsers.
Cube.js (GitHub Repo)
Cube.js is an open source modular framework to build analytical web applications. It is designed to work with large-scale datasets and has implemented various optimization techniques. Businesses can easily build custom intelligence tools or customer-facing analytics without having to worry about performance, SQL code organization, or infrastructure. Data visualization is simple with customizable dashboards.

This has caused mixed reactions, with some teenagers feeling that it was a breach of trust with their parents, while others are pleased with the fact that they are ‘famous’ on the internet.
What's the Weather on Mars? NASA's InSight Now Providing Daily Reports (2 minute read)
In order to tell the difference between a gust of wind and a ‘marsquake’, NASA needed to implement weather sensing capabilities into its InSight lander. The lander records daily temperatures, air pressure, and wind speed and direction. It is currently winter in Elysium Planitia, where the InSight lander is located, with temperatures ranging from 15 Fahrenheit (-9 Celsius) to -80 Fahrenheit (-60 Celsius). Other strange phenomenon has also been recorded, such as dust devils strong enough to tilt the ground beneath the lander.
