The origins of handedness in life

Handedness is a complicated business. To simply say life is left-handed doesn't even begin to capture the blooming hierarchy of binary refinements it continues to evolve. Over the years there have been numerous imaginative ...

Researchers unlock mystery of how 'handedness' arises

The overwhelming majority of proteins and other functional molecules in our bodies display a striking molecular characteristic: They can exist in two distinct forms that are mirror images of each other, like your right hand ...

Right/left handedness of snails changed in the lab

(PhysOrg.com) -- Like most animals, snails have either left- or right-handed asymmetry (chirality), both internally and externally, and the handedness is hereditary. A new study has for the first time found that handedness, ...

Lefties are all right with kangaroos

Kangaroos prefer to use one of their hands over the other for everyday tasks in much the same way that humans do, with one notable difference: generally speaking, kangaroos are lefties. The finding, reported in the Cell Press ...

Beer's bitter compounds could help brew new medicines

(Phys.org)—Researchers employing a century-old observational technique have determined the precise configuration of humulones, substances derived from hops that give beer its distinctive flavor.

Efficient catalysis on chiral surfaces

(Phys.org)—Practice is when everything works but nobody knows why. This light-hearted saying can equally be applied to chemical processes. "The process of so-called heterogeneous asymmetric catalysis is very easy to use ...
