Biological engineers have created a multitissue model that lets them study the relationships between different organs and the immune system on a microfluidic chip seeded with human cells. With this ‘organs-on-a-chip’ model, they could explore the role of immune cells in ulcerative colitis and other inflammatory diseases. Source: Using 'organs-on-a-chip' to model complicated diseases

Infants from rural families tend to display negative emotions such as anger and frustration more frequently than their urban counterparts, according to a recent study. Babies born in big cities, on the other hand, typically are less fussy and not as bothered by limits set by their caregivers. Source: Where you live may influence your […]

Ion channels, which allow potassium and sodium ions to flow in and out of cells, are crucial in neuronal ‘firing’ in the central nervous system and for brain and heart function. These channels use a ”ball-and-chain” mechanism to help regulate their ion flow, according to a new study. Source: Ball-and-chain inactivation of ion channels visualized […]

A puzzling modification of DNA that is typical in bacteria does not occur in humans or other mammals. This has been shown in a new study. The study shows that findings from the epigenetic marker 6mdA in animals are probably the result of limitations in technology and bacterial contamination of samples.

A recent study in mice led a team of researchers in Japan to believe that psychosis may be caused by problems with specialized nerve cells deep within the brain, as well as a certain kind of learning behavior. The researchers hope this could provide insight into the emergence of delusions in patients with psychosis or […]

With the help of photolithography and programmable DNA, researchers have created a new technique that can rapidly ‘print’ two-dimensional arrays of cells and proteins that mimic a wide variety of cellular environments in the body. This technique could help scientists develop a better understanding of the complex cell-to-cell messaging that dictates a cell’s final fate. […]

Maggots on a dead body or wound can help pinpoint when a person or animal died, or when maltreatment began in elder, child care or animal neglect cases. However, the current process for making this determination is time consuming and resource intensive. It also relies on species assessment by trained entomologists. Now, researchers report the […]
