Water was plentiful in the early universe

Astronomers have long held that water—two hydrogen atoms and an oxygen atom—was a relative latecomer to the universe. They believed that any element heavier than helium had to have been formed in the cores of stars and ...

Hydrogen opens the road to graphene ... and graphane

(PhysOrg.com) -- An international research team has discovered a new method to produce belts of graphene called nanoribbons. By using hydrogen, they have managed to unzip single-walled carbon nanotubes. The method also opens ...

Scientists develop new hydrogels for wound management

Open wounds, whether caused by accidents or from medical procedures like surgery, require proper management to speed up healing and prevent infections. While sutures and staples are common wound closure methods, they can ...

Chemical engineers explain oxygen mystery on comets

A Caltech chemical engineer who normally develops new ways to fabricate microprocessors in computers has figured out how to explain a nagging mystery in space—why comets expel oxygen gas, the same gas we humans breathe.

NASA research gives guideline for future alien life search

Astronomers searching the atmospheres of alien worlds for gases that might be produced by life can't rely on the detection of just one type, such as oxygen, ozone, or methane, because in some cases these gases can be produced ...
