Monday marks the 11th International Memorial Day for the "Comfort Women," which refers to victims forced into sexual slavery by Japanese troops during World War II. More than 200,000 Chinese women were tortured between 1931 and 1945 with fewer than 20 survivors still alive today in the Chinese mainland. 

The "comfort women" system was an organized and planned action directly orchestrated by the then Japanese militarist government during World War II and was executed by the Japanese troops. 

The victims of the "comfort women" system were not limited by race or borders. About 400,000 Asian women from China, the Korean Peninsula, Southeast Asia and the European and American countries were forcibly conscripted as "comfort women." 

In a video released by the Memorial Hall of the Victims in Nanjing Massacre by Japanese Invaders on its Sina Weibo, a Chinese "comfort women" survivor recalled her experience and fear of being imprisoned by the Japanese invaders. 

Many netizens left messages online to call on the public not to forget the suffering of "comfort women." 

One netizen said that history will not fade with the passage of time, and facts will not disappear due to eloquent denials, noting that revisiting history is not about indulging in suffering and hatred, but about ensuring that peace endures and justice prevails. Another netizen said that war is like a mirror that allows people to better understand the preciousness of peace. 

In South Korea, there left only nine surviving "comfort women" after one survivor passed away in May this year. All the South Korean survivors are now in their 90s. 

On August 14, 2022, which was designated the International Memorial Day for "Comfort Women" in 2012 by the 11th Asian Alliance Conference for "Comfort Women," South Korean people held a protest rally in Seoul with portraits of "comfort women" and their testimonies.

A newly discovered microbe chows down on polluting plastic.

For humans, polyethylene terephthalate, also known as PET, is a stiff, strong plastic fiber that’s the main ingredient in polyester clothing and disposable bottles. But for the bacterium Ideonella sakaiensis, PET is dinner.

Researchers in Japan discovered the bacterium living in samples of soil, wastewater and recycling plant sludge, all contaminated with PET particles. PET is very stable, and few known microbes can break it down. But I. sakaiensis can use PET as its main food source, the scientists report in the March 11 Science. Tests revealed that the bacterium latches onto PET particles and releases a protein that decomposes the plastic into molecules the bacterium can munch on (SN: 2/20/16, p. 20).

Millions of tons of PET are manufactured yearly, and the long-lasting plastic can pose an environmental threat as it builds up in ecosystems. With its appetite for this environmental hazard, I. sakaiensis might be valuable in plastic waste cleanup, the researchers say.

In the backwaters of the solar system beyond Pluto, lies the dwarf planet Makemake. And the tiny world has an even tinier moon, NASA announced April 26. The moon was spotted as a dark smudge orbiting Makemake in April 2015 images from the Hubble Space Telescope.

Researchers estimate that the moon, temporarily dubbed S/2015 (136472) 1, is roughly 160 kilometers wide; its home world, by comparison, is about 1,400 kilometers across. The satellite appears to trek around Makemake once every 12 days or more, though more observations are needed to nail down its orbit. The moon’s motion can help researchers determine the mass of Makemake, one of the largest known bodies in the Kuiper belt.
