Skin-like test models could help improve medical devices for people of all skin tones

Many medical devices and wearable health sensors work by shining light into the skin and measuring the signal that returns. These technologies are used in products ranging from pulse oximeters to fitness trackers. However, studies have shown that some optical devices can be less accurate for people with darker skin, raising concerns about health care equity and patient safety. In a recent study reported in the Journal of Biomedical Optics, researchers at the VTT Technical Research Centre of Finland addressed this problem by developing realistic skin-like test models that represent a range of skin tones and include artificial blood vessels with flowing blood-like fluid.

Microplastics cross placenta-like barrier and disrupt key pregnancy hormones in new cell model study

Tiny, near-invisible fragments of plastic shed from the products we use every day through sunlight and mechanical wear have been quietly working their way deep into the human body. Microplastics have already been found in the human brain, semen and even the placenta. A recent study investigated how these micro- and nanoplastics (MNPs) might move through the placenta and whether they affect a baby’s development.
