If you’re old enough, you might remember how some flowers around where you live blossom earlier or that summers and winters are unusually harsh. In short, freak weather is more common to the point it’s becoming the new norm. Human memory is fallible, which is why we keep records of things like temperature, humidity, concentration of gases in the atmosphere and so on. These record don’t go back that long though — maybe only a century. Some, however, go way back and scientists are using these to keep track of climate change over the centuries.
Wastewater spills from hydraulic fracking in North Dakota caused widespread water and soil contamination, a new Duke University study finds. Hydraulic fracking involves injecting highly pressurized fluids into subsurface rocks, creating a system of fissures through which the hydrocarbons can escape. There are many environmental issues associated with this technique, one of them being that the entire thing is difficult to control.
According to the Renewables Global Status Report (GSR) from REN21, roughly a fifth of the world’s electrical power production now comes from renewable sources. When will we see a full transition, though?
There’s good bacteria and bad bacteria, but the gut seems to be so diverse in its bacterial offering from person to person that scientists have always found it difficult to say “hey, this is what a healthy microbiome should look like.” Analyzing thousands of bacteria species in your guy is challenging and we’re still not there, but a recent effort involving 4,000 participants has some good hints as to what makes a healthy gut.
The visual effect was extremely strong, and everything was completely safe, activists say.

Lions previously held by circuses across South America were rescued and will be flown back to Africa, where they will spend the rest of their days in a safe sanctuary. It almost seems like a fairy-tale ending – after spending most or all of their life trapped in circuses in appalling conditions, these lions will finally get the chance to
