In Japan has developed a plastic bags decomposing in sea water

The Japanese company Mitsubishi Chemical announced the development of plastic packages that degrade in seawater, transmits television channel NHK.

The bags are made from a material which includes, in particular, sugar cane. To the touch this package will not differ from the usual plastic.

Traces of plutonium from the damaged Fukushima reactors have been found throughout Japan

Scientists from six countries using advanced analytical techniques found that the plutonium contained in nuclear fuel plant Fukushima-1, destroyed in March 2011, still contained in the environment in the composition of micro-particles ejected during an accident. The study is published in the journal Science of the Total Environment.

Environmentalists and chemists previously noted that the materials released into the atmosphere, soil and seawater after the accident, contained traces of plutonium, but its physical, chemical and isotopic forms remained unknown.

Aardvarks have changed their behavior due to global warming

South African scientists have discovered that aardvarks are usually active only at night, began to leave in search of food during the day. The researchers suggest that this is due to climate change and lack of food. Violation of circadian rhythm, according to biologists, may have a negative impact on the survival of these rare mammals and lead to the disruption of the ecosystem as a whole. The study is published in the journal Frontiers in Physiology.

The African aardvark is the only modern representative of the relic squad trubkozuby. Animals remained only in Africa South of the Sahara. They lead a solitary lifestyle, living in burrows, feed on ants and termites.

Tree rings confirmed climate change

The study of annual rings in tree cross-section for the last 600 years showed that extreme climate change began in the middle of the last century. The results were published in the journal Proceedings of the National Academy of Sciences.

Annual rings of trees is a natural document that tells about the climate in a particular period. Working on the creation of the South American drought Atlas (SADA), the scientists analyzed how over the past six centuries, changed the moisture content of the soil in which the trees grow.

Scientists told about the fate of killer whales and belugas from the "whale jail"

Released of killer whales took in the wild families of their relatives, they sailed into the Pacific ocean, plump Beluga whales often seen on the coast of Primorye, they are not afraid to approach people, told RIA Novosti in the press service of the all-Russian research Institute of fisheries and Oceanography (VNIRO) in world oceans day, celebrated on 8 June.

As explained by scientists, during the summer and early autumn of orcas kept in the Shantar area in the North-Western part of the Okhotsk sea, cruising in their traditional summer hunting: Bay Academy, Tugurskiy Bay Udskoe lip.

Named the place with the cleanest air on Earth

Researchers from the University of Colorado (USA) and Australian colleagues have identified the region with the cleanest air on the planet. The work of scientists published in the journal Proceedings of the Natural Academy of Sciences (PNAS).

Due to human activities on Land are almost no places with a "pristine" environment. Scientists have suggested that the clean air can be detected over the so-called Southern ocean – a collection of Pacific, Atlantic and Indian oceans surrounding Antarctica. These places, according to the authors of the study, almost did not felt the influence of aerosol pollution and dust from the continents.
