Credit: Carnegie Mellon University and Northeastern University Batteries have come a long way since Volta first stacked copper and zinc discs together 200 years ago. While the technology has continued to evolve from lead-acid to lithium-ion, many challenges still exist--like achieving higher density and suppressing dendrite growth. Experts are racing to address the growing, global need for energy-efficient and safe batteries. The electrification of heavy-duty vehicles and aircraft requires batteries with more energy density. A team of researchers believes a paradigm shift is necessary to mak...

The research team integrated systems metabolic engineering and membrane engineering strategies for the production of seven natural rainbow c...

Real-world data from Sleep Number® smart bed sleepers shows a potential model for predicting and tracking COVID-19 infection using sleep and biometric measures. Analysis of 18.2 million 360 smart bed sleep sessions finds heart rate variability differs with age, gender and day of the week.

 E-Mail For decades, physicians and dieticians have urged people to limit their intake of high fat foods, citing links to poor health outcomes and some of the leading causes of death in the U.S., such as diabetes, heart disease and cancer. According to the Centers for Disease Control and Prevention, dietary components high in saturated fats such as red meat are thought to be risk factors for colon cancer. Diet is thought to strongly influence the risk of colorectal cancer, and changes in food habits might reduce up to 70% of this cancer burden. Other known epidemiological risk factors are f...
