Scientists set out to study Earth’s most forbidding – and Mars-like – locations

If we want to find life on Mars it might help to study the most forbidding places on Earth. And it turns out there are four places so inhospitable – too cold, dry, hot or salty – that match the conditions on Mars 델타포스 다운로드. A team of scientists visited these sites to see if life can survive.

The four places are:

  • Chott-el Jerid, a salt pan in Tunisia
  • Atacama desert in Chile
  • Rio Tinto in Southern Spain
  • Deception Island in Antarctica

From AstroBiology:

“The big questions are: what is life, how can we define it and what are the requirements for supporting life 카카오톡 맥용 다운로드? To understand the results we receive back from missions like Curiosity, we need to have detailed knowledge of similar environments on Earth. In the field campaigns, we have studied ecosystems…found a range of complex chemical processes that allow life to survive in unexpected places.”

The results are helping to guide NASA’s mission to Mars with the rover Curiosity 다운로드. Hinting at places where life might be found, how cloud cover can help create moisture, and showing that bacteria can survive just below the surface.

Average annual hours worked per country

“Over the last century, you’ve seen a reduction from very long working hours – nearly 3,000 a year at the beginning of the 1900s – to the turn of the 21st Century when most developing countries were under 1,800 hours,” says Messenger 다운로드. “And indeed some of the most productive countries were even lower than that.”

A look at the average annual hours worked per person in selected countries puts South Korea top with a whopping 2,193 hours, followed by Chile on 2,068 내 전화번호.

British workers clock up 1,647 hours and Germans 1,408 – putting them at the bottom of the table, above only the Netherlands.

Greek workers have had a bad press recently but, as we reported in February, they work longer hours than any other Europeans. Their average of 2,017 hours a year puts them third in the international ranking, based on figures compiled by the Organisation for Economic Co-operation and Development (OECD) 아이스크림 타이머 다운로드.

“…the US is the only developed country that has no legal or contractual or collective requirement to provide any minimum amount of annual leave,” he says 다운로드.

The UK, in contrast, is subject to the European working time directive, which requires at least four weeks of paid annual leave for every employee 다운로드.
