Four-story high rogue wave breaks records off the coast of Vancouver Island

A rogue wave measuring 58 feet (17.6 meters) tall was recorded off the coast of Vancouver Island, breaking the record for proportionality at three times the size of surrounding waves.

“Only a few rogue waves in high sea states have been observed directly, and nothing of this magnitude. The probability of such an event occurring is one in 1,300 years,” said Johannes Gemmrich, one of the lead researchers on rogue waves at the University of Victoria.

The wave made a splash in the scientific community for being proportionally the most extreme rogue wave ever recorded. Although it occurred in November 2020, the study confirming it was just released February 2 of this year.

Mystery Tsunami That Spread Around The World in 2021 Can Finally Be Explained

Last year in August, a surprise tsunami in the South Atlantic Ocean mushroomed to distances over 10,000 kilometers (more than 6,000 miles) away, rippling through the North Atlantic, the Pacific, and the Indian Oceans.

It was the first time a tsunami had been recorded in three different oceans since the 2004 Indian Ocean earthquake, and scientists have only just now figured out how the waves were triggered.

The epicenter of the August earthquake was measured 47 kilometers (about 30 miles) below the ocean floor, which is much too deep to initiate a significant tsunami, even one with relatively small waves between 15 and 75 centimeters tall (6 to 30 inches).

Plants help reduce toxic mercury from environment, says study

😀


Plants absorb a vast amount of toxic mercury gas in the atmosphere and help reducing the pollutant worldwide by depositing the element into soils, said researchers.

The process is similar to the absorption of carbon dioxide emissions by plants, said the team from University of Massachusetts Lowell, in the US.

Hundreds of tonnes of mercury each year are emitted into the atmosphere as a gas by burning coal, mining and other industrial and natural processes.

How Left and Right Hippocampal CA1 Regions in the Mouse Brain Talk With Each Other

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.
