Plants generally orient their growth against the direction of gravity. Rotating them around an axis perpendicular to gravity can produce more complicated growth shapes that depend on the speed of rotation. The authors model this behavior and find a stable family of three-dimensional dynamic equilibria.

A rare Stratospheric Warming event has begun over the South Pole : https://www.severe-weather.eu/global-weather/polar-vortex-st…winter-fa/ Comments: https://news.ycombinator.com/item?id=40973342


A Stratospheric Warming event begins over the South Pole, with unusual intensity, raising question about a potential impact on the Northern Hemisphere and the U.S. Winter weather.

The U.S. High Speed Rail Association (USHSR) published a map outlining its proposal for a new 17,000-mile national high-speed rail network across the United States, which it claims will “cut our carbon footprint by epic proportions.”

Under the plan, which the USHSR proposes to build in four stages, it would be possible to travel between Seattle, Washington; San Diego, California; Miami, Florida; and Boston, Massachusetts, entirely on 220-mile-per-hour high-speed rail lines.

The past few years have seen a renaissance in high-speed rail interest across the United States, following decades of little activity. A number of lines are either proposed or under construction. Integrated high-speed rail networks already exist across much of Western Europe, Japan, and China, which, according to Statista, had a 25,000-mile-long network in 2021.
