BBC: Humans' early arrival in Britain

Researchers have discovered stone tools in Norfolk, UK, that suggest that early humans arrived in Britain nearly a million years ago - or even earlier.

The find, published in the journal Nature, pushes back the arrival of the first humans in what is now the UK by several hundred thousand years.

Environmental data suggests that temperatures were relatively cool.

This raises the possibility that these early Britons may have been among the first humans to use fire to keep warm.

They may also have been some of the earliest humans to wear fur clothing.

Exposed: The truth about Israel's land grab in the West Bank

As President Barack Obama and Israeli Prime Minister Benjamin Netanyahu meet, a report reveals 42 per cent of territory is controlled by settlers

Jewish settlers, who claim a divine right to the whole of Israel, now control more than 42 per cent of the occupied West Bank, representing a powerful obstacle to the creation of a Palestinian state, a new report has revealed.

Settlers from God! Religion Poisons Everything!

The jurisdiction of some 200 settlements, illegal under international law, cover much more of the occupied Palestinian territory than previously thought. And a large section of the land has been seized from private Palestinian landowners in defiance even of an Israeli supreme court ruling, the report said, a finding which sits uncomfortably with Israeli claims that it builds only on state land.

Drawing on official Israeli military maps and population statistics, the leading Israeli human rights group, B'Tselem, compiled the new findings, which were released just as the Israeli prime minister, Benjamin Netanyahu, arrived in Washington to try to heal a gaping rift with US President Barack Obama over the issue of settlements.

Planck telescope sends back a postcard of the universe


The Guardian Newspaper: This image from the Planck telescope is a first instalment from its survey of the universe's hidden structure

Giant clouds of interstellar gas and dust light up this panoramic view of the sky recorded by the European Space Agency's Planck telescope.

The space telescope was launched in May last year on a mission to survey the "cosmic microwave background" – ancient light left over from the big bang.

The bright streak across the middle of the picture is our own galaxy, the Milky Way, viewed edge-on. The intense light comes not from stars but from the radiation released by the dust and gas clouds that stretch between them.

"We are opening the door to an El Dorado where scientists can seek the nuggets that will lead to deeper understanding of how our universe came to be and how it works now. The image itself and its remarkable quality is a tribute to the engineers who built and have operated Planck," said David Southwood, director of science and robotic exploration at the European Space Agency (Esa).

The blue and white wisps that reach above and below our own galaxy are streamers of cold dust that trace out the "galactic web" where new stars are born.

The speckles at the top and bottom of the image are caused by microwave background radiation, the remnants of the first light that appeared 380,000 years after the big bang flung the universe into being 13.7bn years ago.
