    ‘Molecular prosthetics’ can replace missing proteins to treat disease

    Researchers have demonstrated that a small molecule can transport iron in human cells and live animals when proteins that normally do the same job are missing, a condition that often causes severe anemia in patients. Such “molecular prosthetics” might treat a host of incurable diseases caused by protein deficiencies, such as anemias, cystic fibrosis or certain types of heart disease.

    A 10-week muscle-building and dietary program involving 50 middle-aged adults found no evidence that eating a high-protein diet increased strength or muscle mass more than consuming a moderate amount of protein while training. The intervention involved a standard strength-training protocol with sessions three times per week. None of the participants had previous weightlifting experience.

  • Researchers tested 11 household fabrics that are commonly used for homemade masks and found that all are effective at curbing the small and large respiratory droplets that are released when we speak, cough or sneeze.

    Studies indicate that homemade masks help combat the spread of viruses like COVID-19 when combined with frequent hand-washing and physical distancing. Many of these studies focus on the transfer of tiny aerosol particles; however, researchers say that speaking, coughing and sneezing generates larger droplets that carry virus particles. Because of this, mechanical engineer Taher Saif said the established knowledge may not be enough to determine how the effectiveness of some fabrics used in homemade masks.
