A New Study Has Identified a Dominant Force Driving Evolution on Earth Today
Mounting evidence suggests humans are now a major driving force of evolution on Earth. From selective breeding to environmental modifications, we're altering so much of our world that we're not only now driving the climate, but the direction of life

Earth's core is neither solid iron, nor liquid. It's a whole lot weirder
We've known for a while that Earth's deepest depths, its "solid iron" inner core, isn't made of pure iron — and now scientists say it might not be solid either.

1 in 3 Americans now 'alarmed' by climate change. Why aren't our leaders?
New results from a long-running public opinion survey show that about 1 in 3 Americans is now "alarmed" by global warming. Is it any wonder, given the horrific onslaught of fires, floods, heat waves and other climate disasters we've experienced in the last year alone?

New theory for the Earth's core
The Earth’s core consists of two parts: a solid inner iron core with a radius of 1,220 kilometers (slightly smaller than the Moon), and the outer core, a 2,500-kilometer-thick molten iron shell. The depth, pressure and temperatures of the core do not make it possible to access it by any technical means. That is why there are many questions both about its composition and its mechanisms.

With climate change, seemingly small shifts have big consequences
Climate change has been accumulating slowly but relentlessly for decades. The changes might sound small when you hear about them—another tenth of a degree warmer, another centimeter of sea level rise—but seemingly small changes can have big effects on the world around us, especially regionally.

Beer byproduct mixed with manure proves an excellent pesticide
The use of many chemical fumigants in agriculture have been demonstrated to be harmful to human health and the environment and therefore banned from use. Now, in an effort to reduce waste from the agricultural industry and reduce the amounts of harmful chemicals used, researchers have investigated using organic byproducts from beer production and farming as a potential method to disinfest soils, preserve healthy soil microorganisms and increase crop yields.

What could happen to change gravity on Earth as we know it?
There are several ways that surface gravity on Earth could change. We wouldn’t like most of them. If a mini black hole collided with Earth and didn’t pass straight through, it would sink to the planet’s centre. Gravity would soar as the entire planet is pulled into the hole. It would probably get very hot too, so no one would survive to see the final spaghettification as we got within a few kilometres of the hole, when we are pulled apart by intense gravity gradients.
