Scientists find that black carbon is a good tracer to separate cooking organic aerosol from traffic-related organic aerosol.

Researchers from EPFL and the University Medical Center Utrecht in the Netherlands have developed an extremely fast optical method for sculpting complex shapes in stem-cell-laden hydrogels and then vascularizing the resulting tissue. Their groundbreaking technique stands to change the field of tissue engineering.

Now, researchers have shown that it is possible to evoke a shift in the metabolism from fermentation to respiration of E. coli and baker's yeast by optimizing fermentation conditions. This shift means that the cells can be pushed into producing more internal energy (ATP).

Japanese scientists at Tokyo University of Agriculture and Technology (TUAT) have found that for stroke patients, observing their own hand movements in a video-assisted therapy -- as opposed to someone else's hand -- could enhance brain activity and speed up rehabilitation.

A sophisticated chip the size of a coin in which cartilage can be cultivated and which can later be subjected to mechanical stress such that it generates the effects of Osteoarthrosis (OA).

In their paper published Aug. 23, 2019 in Cancer Prevention Research, University of Massachusetts Amherst food scientists showed that feeding frying oil to mice exaggerated colonic inflammation, enhanced tumor growth and worsened gut leakage, spreading bacteria or toxic bacterial products into the bloodstream.

Researchers from Carnegie Mellon University and Nanyang Technological University, Singapore have developed an organ-on-an-electronic-chip platform, which uses bioelectrical sensors to measure the electrophysiology of the heart cells in three dimensions. These 3D, self-rolling biosensor arrays coil up over heart cell spheroid tissues to form an 'organ-on-e-chip,' thus enabling the researchers to study how cells communicate with each other in multicellular systems such as the heart.

Researchers at Binghamton University, State University of New York have discovered the mechanism through which ultraviolet radiation, given off by the sun, damages our skin.
