Structure of fat-processing enzyme determined

After decades of work with no success, researchers have determined the high-resolution, three-dimensional structure for lipoprotein lipase, the enzyme that processes fats, or triglycerides, in the bloodstream and releases ...

Linking sensing to signaling during plant immunity

Plant defense against invading pathogens relies upon effective recognition of non-self organisms and a subsequent signaling response characterized by reprogramming of host gene expression and localized cell death to combat ...

Advancing the science of smell—with a hint of musk

Researchers have identified key molecular mechanisms at work when people smell musks, a highly valued group of fixatives used in many perfumes and colognes. The discovery may have implications for a wide range of effects ...

First oceans may have been acidic

One way to understand how ocean acidity can change, for example, in response to rising carbon dioxide (CO2) levels, is to look to the history of seawater acidity. Dr. Itay Halevy of the Weizmann Institute of Science has looked ...

Proteins assemble and disassemble on command

Scientists have deciphered the genetic code that instructs proteins to either self-assemble or disassemble in response to environmental stimuli, such as changes in temperature, salinity or acidity. The discovery provides ...
