Up, up and away: Chemists say 'yes,' helium can form compounds

Can helium bond with other elements to form a stable compound? Students attentive to Utah State University professor Alex Boldyrev's introductory chemistry lectures would immediately respond "no." And they'd be correct – ...

Melting solid below the freezing point

Phase transitions surround us—for instance, liquid water changes to ice when frozen and to steam when boiled. Now, researchers at the Carnegie Institution for Science have discovered a new phenomenon of so-called metastability ...

New method of studying environmental toxins

In 1986, Gordon Brown used SLAC's Stanford Synchrotron Radiation Lightsource (SSRL) to visualize something no one had ever seen before: the exact way that atoms bond to a solid surface. The work stemmed from a eureka moment ...

Going against the grain—nitrogen turns out to be hypersociable

Nitrogen is everywhere—there is four times as much of it as oxygen in Earth's atmosphere. However, it is reluctant to form chemical bonds, especially with more than four atoms. Chemists from Warsaw predict, however, that ...

Scientists persuade nature to make silicon-carbon bonds

A new study is the first to show that living organisms can be persuaded to make silicon-carbon bonds—something only chemists had done before. Scientists at Caltech "bred" a bacterial protein to make the man-made bonds—a ...
