According to Di-Jia Liu, a chemist at the Argonne National Laboratory in the US, the carbon atoms (原子) in CO2 and the hydrogen (氢) atoms in water can be combined to make methane (甲烷) or ethanol (乙醇). They could be used as fuel. If we do this on Mars, energy from the ...

Humans began overfishing (过度捕捞) in the 19th century. Today, there are many fishing ships in the world to catch fish. In other words, we are taking away too many fish from the world’s oceans (海洋) . Fish can’t grow fast enough, so the number of species (物种) of fish is dr...
The theory of evolution proposes that life and humans arose through a natural process. A very large number of people do not believe this, which is something that keeps evolution in the news. In this article, we will explore the theory of evolution and how it works. We will also ...
How do bacteria create colonies in the first place? Bacteria, like other forms of life on Earth, need to make copies of themselves to survive. While humans and other organisms do this through sexual reproduction, it works a bit differently with bacteria. But first, we'll discuss why diversit...
The Earth became covered in a thin layer of lead, and lead is toxic to many living things (including humans). When lead was banned, gasoline got more expensive because refineries could not boost the octane ratings of cheaper grades any more. Airplanes are still allowed to use leaded gasoline...
Traditionally, this task is done by humans visually inspecting each and every image—but human eyes are limited in their capabilities, and we also only have so many waking hours to work and few scientists to get it all done. Not only is machine learning faster, but these algorithms can pin...
humans or animals, whatever kind of baby it is, but all is not lost. Join us today for an exploration of microplastics and nanoplastics and what we can do to dig out from underneath this mountain of plastic under which we have buried ourselves. Here we go with Matthew Simon....
