GM wants to sell electric car with autonomy of 320 kilometers in 2017

General Motors (GM) is expected to launch in 2017 a cheaper electric car and battery life up to 320 kilometres, according to The Wall Street Journal. The information, revealed also by AP, is expected to be announced today by the company itself, at the North American International Auto Show in Detroit, the United States.

According to press reports, the car could cost up to € 25,000 ($ 80,000) in the United States and it's going to be called Chevrolet Bolt.

How to survive marine otters in icy waters without becoming hypothermic.

Many of the mammals that live in the ocean â€" and that during the winter have to face icy waters â€" turn to body fat to keep the internal temperature constant, as in the case of whales, walruses, dolphins, sea lions and many others.

The Sea Otter is also a mammal that swims in freezing waters in winter and not to die of cold has to maintain an internal temperature of about 37.7 degrees Celsius, almost twice the water temperature where nothing. But how does this animal to keep body temperature constant and avoid hypothermia?

Unlike the large mammals, the Otter is small, which means you're always losing heat. In evolutionary terms, the Otter is relatively recent, having only appeared there are 1.6 million years. Already the whales emerged there are 50 million years, the sea lions between 23 to 29 million years, which is enough time to adapt to life in the ocean.

The secret of the otters to cope with low temperatures is fur, which is the thickest of all the animals on the planet, about a million by 2.5 inches square, writes the TreeHugger. The hair, which is waterproof, lets still imprison air near the surface of the skin, which helps keep the temperature and gives the characteristic bright aspect of the otters when they're in the water.

It was also this hair that almost caused the extinction of the species. During the 19th century marine otters were hunted extensively almost to extinction, for the manufacture of hats and coats.

Although the population of otters have recovered gradually over the years, the International Union for conservation of nature continues to classify these animals with the status of threatened. Currently, the greatest danger for the otters is not hunting for the production of clothing, since the species is protected internationally, but oil spills.

The oil interferes with the impermeability of the hair, in addition to making the otters patients due to toxins that they ingest.

Marine otters play an important role in terrestrial ecosystem and mitigate some of the environmental impacts of human activity. The otters help protect the kelp-Kelp algae, an order large algae that belong to the class Phaeophyceae â€" of sea urchins, which in turn slow down global warming.

Thus, it is important to protect this animal, not only for not perish but also to mitigate global warming.

Mysterious and legendary metal retrieved from the ship which sank in the 6th century BC.

Legend has it that, when Atlantis (pictured fictionalised) submerged in the ocean, took all the orichalcum can't. This metal, is quoted in various ancient texts, including the criticism of Plato, and considered the second most valuable metal after gold.

Now, a team of divers announced the discovery of 39 blocks of orichalcum on a ship that was wrecked in the 6th century BCE, near Sicily. According to Discovery News, the ship will have left Greece or elsewhere in Asia minor, and was carrying metal to Gela in southern Sicily, having been caught in a storm and wrecked the 300 metres from the harbour.

"Never found anything like it. We know the orichalcum of ancient texts and a few ornamental objects, "said Sebastiano Tusa, responsible for the Ministry of the sea of Sicily.

Experts claim that the orichalcum is a bronze alloy, developed by reaction of zinc ore, coal and copper metal. When the new bricks were analyzed by x-ray, explains the Discovery, it was discovered that the metal had 75 to 80% copper, 15 to 20% zinc and small percentages of nickel, lead and iron.

Currently, the team of Tusa's working in excavations related to the rest of the ship, which may reveal new findings about the work of artisans of antiquity.

Most of the reserves of fossil fuels will have to be explored to avoid climate change

Most of the vast oil reserves of the former USSR, the United States, the Arctic and the Middle East, as well as coal from China and from the African continent may have to remain unfulfilled in order to avoid serious climate change. The conclusion of a new study that analyzed the fossil fuel reserves that cannot be exploited.

According to the study by two researchers at the University College of London, one-third of oil, half of the natural gas and more than 80% of the existing coal reserves will have to remain underground in order to avoid global warming more than two degrees Celsius by 2100. The study reinforces the idea that companies and investors should consider carefully the reserves of fossil fuels as financial assets. The idea also applies to countries whose economies rely heavily on these natural resources.

This is not the first research to calculate the amount of reserves that must be explored. However, the analysis of Christophe McGlade and Paul Ekins is the first to present a meticulous level of detail, indicating what could happen to the production of fossil fuels in the different areas of the globe.

"We now have tangible figures on the quantities and locations of fossil fuels that should be explored in an attempt to limit warming to two degrees Celsius," said Christophe McGlade to the Guardian.

Reservations must be indicated in the unexplored study result from the difference between the amount of greenhouse gases that would be released if all reservations were exploited and the maximum amount of these gases that can be released into the air so that the temperature does not increase by more than two degrees by the end of the century.
