It’s all very well choosing not to eat genetically modified (GM) food, or even banning it entirely, but what if you then rear your cows on GM soya? Can you really maintain a consistent moral objection?

The Calbuco volcano, a 2,000 meter peak in southern Chile, sent a column of ash about 15 kilometers skywards twice on the night of April 22 and early the following morning. 

As the risk of deadly flows of ash and hot air was immediate, a 20 kilometer radius evacuation zone was declared.

The event was spectacularly visible from Puerto Montt, a city of nearly 200,000 inhabitants, only 30 km away. It seems to have begun within barely five hours of warning signs being first detected by local seismometers.

Renewable electricity has nearly trebled under this government.

said Ed Davey, Liberal Democrat energy and climate change minister, during an environment debate held by the Daily Politics show.

Amid the climate of mistrust about claims made by politicians that tends to accompany election campaigns, it is reassuring to report that the evidence supports the minister’s statement.

Recent advances with so-called meta-materials have shown that a practical invisibility cloak might one day be possible. But a new study has approached the scenario from the other direction, asking what it would feel like to be invisible. The answer, it turns out, is it would make us feel more confident.

Have you ever wondered what those food additive numbers in the ingredients list on your food packaging meant and what they were really doing to your body?

A recent study suggests emulsifiers – detergent-like food additives found in a variety of processed foods – have the potential to damage the intestinal barrier, leading to inflammation and increasing our risk of chronic disease.

The research was done on mice, so it’s too early to say humans should stop eating emulsifiers, but let’s examine the mechanisms involved.

As we celebrate Earth Day this week, it is an opportune time to recognize that not all Americans have equally enjoyed the dividends of our nation’s environmental protections.

Decades of research clearly demonstrate that poor and minority communities often experience more environmental burdens and enjoy fewer environmental amenities. These communities tend to host a disproportionate number of landfills, incinerators and other polluting facilities. These are not only unpleasant to live by but also can pose significant health risks.
