Research: The body's fat-metabolism causes detoxification of harmful substances from blood sugar

For several years, medical researchers, doctors, and dieticians have known that a low carbohydrate diet and plentiful fat can prevent a range of lifestyle and age-related diseases and thus promote healthy aging. But researchers from around the world have not been able to explain why this is the case.

Penn study provides insight into how cells maintain identity during replication

Prior to cell division, chromosomes are seemingly a jumbled mess. During cell division, parent cell chromosomes and their duplicates sort themselves out by condensing, becoming thousands of times more compact than at any other time.

DNA robot sorts molecules without external input

Researchers at the California Institute of Technology have developed an autonomous molecular machine comprising a single strand of DNA that can move around, collect specific molecules and sort them into predefined locations. Furthermore, this nanobot has been designed in such a way that requires no external source of energy or instruction.

Study provides first structural glimpse of circadian clock's molecular machinery

Scientists have long known that circadian clocks- biochemical oscillators that control physiology, metabolism and behavior on a roughly 24-hour cycle- are present in all forms of life, including animals, plants, fungi and some types of bacteria. However, the molecular mechanisms that "run" these systems remain largely unknown.

Seeing the full picture, real-time analysis of live-cells

Every cell is a miniature factory taking in raw material (extracellular signals) and processing it to produce something (a biological response). But unlike a factory that can be easily tweaked to run at steady-state and look the same from day to day, cells are dynamic.

Study identifies novel source for brain's development

A study conducted by a team of researchers at the New York University has found an unexpected source for the development of the brain. According to the research, which was published in the journal Science, a group of non-neuronal cells called glia, which were previously considered as passive support cells, are important for the development of nerve-cells present in the brain.
