While cesium from both the nuclear weapons testing and the Chernobyl accident spread through the soil, [cesium seeps very slowly.] Deer truffles, located between 20 and 40 centimeters, have already absorbed the “older” cesium from six decades ago.

Waste coffee grounds make concrete 30% stronger

Researchers have found that concrete can be made 30% stronger by replacing a percentage of sand with spent coffee grounds, an organic waste product produced in huge amounts that usually ends up in landfill. The method also reduces the use of natural resources like sand, further contributing to a greener circular economy approach to construction.

[A doctoral study] has found that the behavior of small perch exposed to bioplastics in fish food changed over a period of six months. They reacted far more when they met fellow perch than normal. In addition, there were signs of reduced movement, altered ability to form shoals and altered reaction when approached by danger.
