Summary: Researchers have uncovered neural circuitry that allows the CA1 region of the hippocampus to communicate with its counterpart in the opposite hemisphere despite there being no connection between them.

RIKEN neuroscientists have uncovered the neural circuitry that permits a subregion in the hippocampus to communicate with its counterpart in the opposite hemisphere despite there being no direct connection between them. While not directly applicable to people, this finding is important for informing future studies of the mouse brain.
The hippocampus is well known for its role in learning and memory. Vertebrates have two hippocampi: one on the left side of the brain and the other on the right. Each hippocampus has various subregions, including the CA1 and CA3 areas.
California’s effort to create high-speed rail line to cost another $5B more
New cost of California’s plan to bring high-speed rail to the state is now $105 billion. It started 14 years ago at $40 billion.
Telecommunications bit rates 1798–2120
This graph shows the progress in telecommunications bit rates over the last two centuries, and a future extrapolation to the 22nd century.
A primitive form of telecommunications emerged in the late 18th century, when French inventor Claude Chappe demonstrated a practical semaphore system that delivered messages between Paris and Lille. Known as the optical telegraph, it had a transmission rate of two to three symbols (196 different types) each minute, or about 0.4 b/s.
The electrical telegraph, popularised in the 1840s, used a coding system developed by American inventor Samuel Morse, which encoded text characters as sequences of two different signal durations, called dots and dashes. It achieved a rate of approximately 100 b/s.
More than 60 years on, Japan’s mercury-poison victims fight to be heard
Shinobu Sakamoto was just 15 when she left her home in the southern Japanese fishing village of Minamata to go to Stockholm and tell the world of the horrors of mercury poisoning.
Speed breeding is a powerful tool to accelerate crop research and breeding
Circa 2018 😀
Fully enclosed, controlled-environment growth chambers can accelerate plant development. Such ‘speed breeding’ reduces generation times to accelerate crop breeding and research programmes, and can integrate with other modern crop breeding technologies.
Michigan will get a new graphite processing factory to support US EV battery production
There have been almost no capabilities of processing graphite outside of China to date, but this new Michigan factory will change that.
Tesla gets all its Supercharger cables stolen at brand new station
Tesla was the victim of a theft that resulted in having to shut down a brand new Supercharger station, as all the cables on the eight stalls were cut off.
The automaker is currently working to triple the size of its Supercharger network over the next two years.
It is currently growing at a record pace.
Meteorite older than Earth likely came from a “protoplanet”
The rock, found in the Sahara, likely comes from a long-lost baby protoplanet.
