When assessing whether preschoolers are overweight, health professionals should use other measures such as waist-to-height ratio in addition to the body mass index (BMI). A study shows that this is because measuring the BMI of younger children often fails to identify those with excess stomach fat and possible associated health problems.
Cancer: Establishing metastasis
Scientists have discovered that a protein called VRK1 might help cancer to take root in new parts of the body. VRK1 was discovered to be necessary for mesenchymal-to-epithelial transition, which scientists suspect may be important for the establishment of metastasis.
Indoor HEPA filters significantly reduce pollution indoors when outside air unhealthy, study finds
Outdoor air pollution is a major contributor to indoor air pollution — but high-efficiency particulate air (HEPA) filters used in the home significantly reduce fine-particulate matter in the air compared with non-HEPA air filters, according to a new study.
