Research on sweat glands suggests a route to better skin grafts

17/01/2017

As early humans shed the hairy coats of their closest evolutionary ancestors, they also gained a distinct feature that would prove critical to their success: a type of sweat gland that allows the body to cool down quickly. Those tiny glands are enormously useful, allowing us to live in a wide variety of climates, and enabling us to run long distances.

Scientists tissue-engineer part of human stomach in laboratory

17/01/2017

Scientists report in Nature using pluripotent stem cells to generate human stomach tissues in a petri dish that produce acid and digestive enzymes. Publishing their findings online, researchers at Cincinnati Children's Hospital Medical Center grew tissues from the stomach's corpus/fundus region.

Multiregional brain on a chip

16/01/2017

Harvard University researchers have developed a multiregional brain-on-a-chip that models the connectivity between three distinct regions of the brain. The in vitro model was used to extensively characterize the differences between neurons from different regions of the brain and to mimic the system's connectivity.

Study unveils how stress may increase risk of heart disease and stroke

13/01/2017

Heightened activity in the amygdala - a region of the brain involved in stress - is associated with a greater risk of heart disease and stroke, according to a study published in The Lancet that provides new insights into the possible mechanism by which stress can lead to cardiovascular disease in humans.

New type of monitoring: life of bacteria in microdroplets

12/01/2017

In the future, it will be possible to carry out tests of new drugs on bacteria much more efficiently using microfluidic devices, since each of the hundreds and thousands of droplets moving through the microchannels can act as separate incubators.

Study finds postdoc jobs in biomedicine don't yield positive returns in the labor market

12/01/2017

A new study by Boston University Questrom School of Business and University of Kansas researchers has found that postdoc jobs don't yield a positive return in the labor market, and that these positions likely cost graduates roughly three years' worth of salary in their first 15 years of their careers.

Aggressive prostate cancer secrets revealed in landmark study

11/01/2017

A landmark study, led by Monash University's Biomedicine Discovery Institute with the involvement of the Peter MacCallum Cancer Centre, has revealed the reason why men with a family history of prostate cancer who also carry the BRCA2 gene fault have a more aggressive form of prostate cancer.

Why high-dose vitamin C kills cancer cells

11/01/2017

Vitamin C has a patchy history as a cancer therapy, but researchers at the University of Iowa believe that is because it has often been used in a way that guarantees failure.
