Arrests at Tiananmen Square Vigil
Today marks the 32nd anniversary of the Tiananmen Square Massacre, when a pro-democracy protest by Chinese students in Beijing turned violent on June 4, 1989. In Hong Kong, commemorations on the anniversary were once a tradition, but that came to an end this year. Police banned any demonstrations relating to the massacre. This did not stop hundreds of activists attending a vigil to commemorate those lost and protest against the government. Hong Kong police broke up the vigil and arrested the organizer, prominent activist Chow Hang Tung. Police cited the coronavirus pandemic as the reasoning for banning any demonstrations, despite no recent cases. The breakup of the vigil comes at a time when Hong Kong is facing pro-democracy issues of its own, as activists regularly face off against police and the government.

Pacific Ocean
Dead Zones in North Pacific
Sediment records reveal that human impact, a warming climate, and nutrient inputs are leading to oceanic dead zones, notably in the North Pacific. Dissolved oxygen content in the entire open ocean has decreased an estimated 2% in the last 50 years, creating dead zones. Dead zones, or Oxygen Minimum Zones (OMZs), are areas with dissolved oxygen in the water below the level needed for marine animals to survive. Evidence indicates that dead zones have been a recurring component of the Pacific during warm interglacial climates for at least 1.2 million years. Dead zones will continue to be an issue, with models predicting a 1% to 7% further decline in global dissolved oxygen by the year 2100.

Q: Running 470 miles (750 km), depending on the season, and at an estimated minimum of 300 million years old, what is believed to be the oldest river in the world?
A: Finke River (Larapinta), Northern Territory, Australia
The Finke River spends a great deal of the year as a series of mudholes or a gently trickling flow drying in central Australia’s arid ground. But when the rain does reach it, it can be a torrent extending to drain into Lake Eyre in South Australia. While dating the age of any river is an inexact science, geologists have good reason to believe that the Finke River’s meanders pre-date the mountains surrounding it, giving a good indication that the Finke and other neighboring rivers of central Australia collectively are the remains of the oldest river network on the planet.
