In recent years, hundreds of new synthetic recreational drugs have emerged – drugs that neither the general public nor the scientific community know very much about.

Many of these new synthetic drugs – often referred to as “legal highs” – are dangerous and continue to lead to poisonings throughout the US and the rest of the world.

These drugs provide similar highs to other, more well-known drugs, like marijuana and cocaine. Many are still legal and others have only recently become illegal.

So why would people use these potentially harmful new drugs?

Most of the times we have looked at Uranus, it has seemed to be a relatively calm place. Well, yes its atmosphere is the coldest place in the solar system.

But, when we picture the seventh planet in our solar system invariably the image of a calming blue hazy disc that the spacecraft Voyager 2 took in 1986 comes to mind.

However, all we have previously known about the atmosphere of Uranus has been ’thrown to the wind’ with observations made last year.

The number of women in paid employment has risen significantly over the past 40 years. In developed countries especially, there are increasing numbers of women reaching top positions in different fields of work. And new research shows how girls are doing far better than boys educationally across the world.

Sunday marks the 106th celebration of International Women’s Day.

Since New Yorkers first celebrated it in 1909, American women have made great strides toward equality in the workplace, politics and at home. Long gone are the days when women couldn’t vote or sex discrimination was blatant and legal.

Planning permission has been given for what could become the world’s largest offshore wind farm on the Dogger Bank, off England’s east coast.

If fully constructed, the project will have up to 400 turbines with a total generation capacity of 2.4 GW. That’s enough to power 1.9 million households – more than Manchester and Birmingham combined.

The NASA spacecraft Dawn has spent more than seven years traveling across the Solar System to intercept the asteroid Vesta and the dwarf planet Ceres.

Now in orbit around Ceres, the probe has returned the first images and data from these distant objects.

But inside Dawn itself is another first – the spacecraft is the first exploratory space mission to use an electrically-powered ion engine rather than conventional rockets.
