The Sun undergoes a type of seasonal variability, with its activity waxing and waning over the course of nearly two years, according to a new study by a team of researchers led by the National Center for Atmospheric Research (NCAR). This behavior affects the peaks and valleys in the approximately 11-year solar cycle, sometimes amplifying and sometimes weakening the solar storms that can buffet Earth’s atmosphere.

Most research on the role of introduced species of plants and animals stresses their negative ecological impacts. But are all introduced species bad actors? In one fascinating case the answer might be no. The iconic giant tortoises of the Galapagos Islands are thriving on a diet heavy on non-native plants. In fact, the tortoises seem to prefer these plants to native ones.

It is estimated that in 2014 over two billion mobile phones were sold worldwide. Of these, over one billion were estimated to be smartphones. It is also estimated that a massive 87% of the world’s population now use mobile phones. These are staggering figures, but how many of us have ever stopped to think of where our precious mobile phones came from and what happens to them once we discard them for a newer model?

Each year millions of mobile phones are produced in the world and an equal number are disposed of. In the vast majority of cases these discarded phones work perfectly well. However, like all technological products these days, phones have a built-in technological obsolescence (we demand the latest model or the latest upgrade) as well as a built in aesthetic obsolescence (we demand the latest style or design).

In spite of their extremely small size and simplicity of look, mobile phones are immensely complex pieces of technology with many, many components. If we stop to think about it for a moment all of these products need sourcing: the raw materials needed to produce them need extracting from the ground, these need to manufactured into working parts which are then assembled into the final phone.

California’s water situation is beyond an emergency, according to Healdsburg resident Dave Howard. He and his sons returned from a “ski trip” in Northern California.

“The peaks are as bald as they normally are in August! Where’s the snow pack that’s supposed to be providing us water all summer? It’s zero folks. There is nothing there,” he said.

They proceeded on to Northstar ski resort. On a normal year there are more than a hundred runs. The temperatures are low enough and Northstar is making it’s own snow. Dave dropped his sons off, to go ahead.

“They did one run, then called me and said, ‘Dad we’re done. This is stupid. There is only one run worth doing and everyone is on it. This is not even worth spending any time on,” said Dave.

He added, “Northstar is scraping for their lives. Where’s their Spring skiing? It doesn’t exist. There in March, they’ve had a bad season already and its not going to get any better. There’s no hope on the horizon for those guys.”

On World Health Day (7 April), European Commissioners Vytenis Andriukaitis and Neven Mimica highlight the importance of food safety, malnutrition, and fighting health threats both in the Union and in developing countries.

2015 is the European year for development (EYD). It is an opportunity to show how EU assistance is improving the lives of millions in developing countries; but also in Europe. Food safety, which is the theme of this year’s World Health Day, is a clear example of this.

Too often in Europe we take for granted that the food on our plates is safe. Europe should be proud that its 500 million consumers benefit from the highest food safety and health protection standards in the world, and that many other countries take them as the norm to be followed. However, we must not become complacent.
