Researchers in the US have shown that the oxide coating on copper nanoparticles can be stripped away by light, exposing the metallic, catalytic copper core. The finding is potentially significant because the oxidation state of many metals dictates their catalytic characteristics, and the ability to tune the oxidation state could open the way to producing more versatile and efficient catalytic systems.

Our bodies and homes are covered in microbes — some good for us, some bad for us, and some just along for the ride. As we learn more about the germs and microbes who share our living spaces, TED Fellow Jessica Green asks: Can we design buildings that encourage happy, healthy microbial environments?

Here we present the selection of the weirdest “handsome” animals in nature. Enjoy!
Scientists have resurrected an extinct frog species, that gives birth through its mouth, by transplanting its DNA into the eggs of another frog species.
The team implant cells of extinct amphibian, collected in the 1970s and kept in deep freezer for 40 years, into the eggs of living relative team implanted cell nuclei from tissues into donor eggs from a distantly-related frog.
Global research efforts to develop new antibiotics need to be accelerated urgently, the UK government’s chief medical officer has warned. She adds that that new drugs are desperately needed to fight the ‘catastrophic threat’ of growing antimicrobial resistance.
Armadillo girdled lizard The armadillo girdled lizard is a lizard endemic to desert areas of southern Africa. It is also known as the typical girdled lizard, armadillo lizard, golden armadillo lizard, and armadillo spiny-tailed lizard. When the armadillo girdled lizard gets frightened, it rolls up into a tight ball to scare away predators. Thorny dragon [...]
