Ubiquitin basics

Despite its discovery as a protein that seems to show up everywhere, at least in eukaryotic cells, researchers are only beginning to scratch the surface of all of the cellular functions involving ubiquitin. 

Ubiquitin Chains in Action

Present in every tissue of the body, ubiquitin appears to be involved in a dizzying array of functions, from cell cycle and division to organelle and ribosome biogenesis, as well as the response to viral infection. The protein plays at least two role

Biofuels by the Numbers

Of the many available no- or low-carbon methods to harvest energy, including wind, geothermal, hydroelectric, and solar approaches, conversion of plant biomass to liquid fuels is the most cost-effective strategy.

Medical Mavericks

ALS patients take their fate into their own hands, self-administering an unapproved chemical and collating their results online.

Slideshows

Printing 3-D Molecules

View some molecular models produced by fast and inexpensive 3-D printing processes, and learn how they’re yielding a fuller understanding of biochemical interactions. 

Meet the Relatives

Meet some of the most famous fossil discoveries of the hominin clan in this slide show. 

Better Biofuel Crops

One way to increase biofuel production is to engineer plants that can withstand harsh environmental conditions, thereby expanding the range in which such crops can be grown.
