Sweating the small stuff

Assistant professor of medical engineering Wei Gao is enriching the field of personalized and precision medicine with an abundant source of chemical data: sweat.

Veritable powerhouses—even without DNA

Whether human beings or animals, plants or algae: the cells of most life forms contain special structures that are responsible for energy production. Referred to as mitochondria, they normally have their own genetic material, ...

Can taking breaks improve how well you do on tests?

Might power naps enhance performance? Perhaps. Short breaks sure do. That is the finding of research by Kristina Lerman, principal scientist at the USC Information Sciences Institute and research associate professor in the ...

Yeast makes ethanol to prevent metabolic overload

Why do some yeast cells produce ethanol? Scientists have wondered about this apparent waste of resources for decades. Now, University of Groningen scientists think they have a solution: yeast cells produce ethanol as a 'safety ...

Using quantum entanglement to study proteins

For the first time, a University of Michigan chemist has used quantum entanglement to examine protein structures, a process that requires only a very small number of photons of light.

Was life on the early Earth purple?

Early life forms on Earth may have been able to generate metabolic energy from sunlight using a purple-pigmented molecule called retinal that possibly predates the evolution of chlorophyll and photosynthesis. If retinal has ...

Bioenergetics

Bioenergetics is the subject of a field of biochemistry that concerns energy flow through living systems. This is an active area of biological research that includes the study of thousands of different cellular processes such as cellular respiration and the many other metabolic processes that can lead to production and utilization of energy in forms such as ATP molecules.
