Researchers have discovered that green tree frogs in the Chernobyl Exclusion Zone have turned dark in order to better mitigate the effects of radiation.

In April of 1986, a reactor at the Chernobyl nuclear power plant in Ukraine exploded, releasing approximately 100 times the energy released by the nuclear bombs of Hiroshima and Nagasaki and drastically altering the lives of both humans and wildlife in the surrounding area. But while authorities were able to evacuate most civilians from the area closest to the nuclear disaster, the animals were left to their own devices. In the decades since, the Chernobyl Exclusion Zone has become a wildlife refuge that offers a unique view into the evolution triggered by the nuclear meltdown.

Deinococcus radiodurans is listed in the Guinness Book of World Records as “the world’s toughest bacterium,” and it is fully deserving of that title.

Scientists discovered the red, spherical bacterium that later came to be known as deinococcus radiodurans about 70 years ago, when examining a can of ground meat that had spoiled despite having been sterilized by exposure to doses of radiation in the megarad range. Research would later show that this lowly bacterium can withstand 10,000 times the amount of radiation that would normally kill a human being, thanks to a miraculous ability to repair numerous DNA double-strand breaks in a matter of hours.

The Ukrainian government has announced the Chernobyl nuclear disaster site will be included in a full scale tourist program.

I know it sounds weird, but tourists have been visiting Chernobyl through unofficial tourism programs, for several years. Authorities are just trying to make things official, so they can actually cash out on the interest people have in the famous contaminated zone. Oddly enough, the Ukrainian Ministry of Emergency will be in charge of operating tours, and although they guarantee every measure will be taken to insure tourists’ safety, Chernobyl isn’t really as safe as they’ll have you think.

On April 26, 1986, reactor number 4 of the local nuclear power station exploded, causing the greatest nuclear disaster in the history of mankind (not counting the ones caused by US nuclear bombs in Japan). A perimeter of 30 miles around the epicenter was closed up to the public, to prevent radioactive contamination, maintained by thousands of technicians, to reduce exposure to radiation. While the catastrophe happened almost a quarter of a century ago, the area around the power station is still very dangerous, especially since the remaining three nuclear reactors have not been shut down, and the shield placed over reactor 4 has been steadily deteriorating, under pressure from within. A new, improved “sarcophagus”, big enough to cover the Statue of Liberty and weighing 20,000 tons, will be ready in 2012.

Ukrainian newspaper Segodnya revealed that a group of independent environmentalists have discovered a zone where radiation level is higher than that of Chernobyl.

The specified area is located in Ukraine’s Dnepropetrovsk region, around an abandoned uranium mine. According to Oleksiy Vedmidsky, a local ecologist, the mine is a huge danger to the people in the region and he has some pretty interesting data to back up his claims. He and his team have recently measured the radiation level around the uranium mine, and the results were nothing less than shocking – “My particle detector measured 2611 micro Roentgen per hour there. Even in the Chernobyl zone near the reactor the exposure is 500-600 micro Roentgen per hour,” Vedmidsky said, pointing out that normal reading is under 30 micro Roentgen per hour.
