Tissues and cells in the human body are subjected to a constant push and pull — strained by other cells, blood pressure and fluid flow, to name a few. The type and direction of the force on a cell alters gene expression by stretching different regions of DNA, researchers at University of Illinois Urbana-Champaign and collaborators in China found in a new study.

The findings could provide insights into physiology and diseases such as fibrosis, cardiovascular disease and malignant cancer, the researchers said.
“Force is everywhere in the human body, and both external and internal forces can influence your body far more than you may have thought,” said study leader Ning Wang, a professor of mechanical science and engineering at Illinois. “These strains profoundly influence cellular behaviors and physiological functions, which are initiated at the level of gene expression.”
The effects of physical forces and signals on cells, tissues and

- Researchers outline three elements of most effective flirtatious look
- Study concludes that flirting has the same weight as other widely-studied emotions
- Result of the study could contribute to today’s debate on consent
By using the Facial Action Coding System (FACS), a team of researchers from the University of Kansas (KU) was able to identify the specific flirtatious look from women that proved to be the most effective cues for men.
In the study published in the Journal of Sex Research, the team determined three elements that made the most obvious flirting cues for men to tell that the females are interested in them. These three elements are —
- Head turned to one side and tilted down slightly
- A slight smile
- Eyes turned forward toward the implied target
To conduct the study, the researchers asked women volunteers to show them their most flirtatious look when conveying their romantic or
