But researchers studying blood samples from more than 12,000 individuals in Ethiopia now estimate these tests missed nearly 10% of malaria cases caused by the parasite Plasmodium falciparum, the most common cause of malaria cases and deaths. |
| Past suffering can affect future praise Posted: 28 Sep 2021 02:19 PM PDT Researchers have discovered that people tend to give more praise to someone for their good deeds as an adult after discovering that person has also had to overcome adversity or suffering earlier in life, such as abuse and neglect as a child. |
| Reducing salt in bread without sacrificing taste Posted: 28 Sep 2021 02:19 PM PDT Most people in the U.S. consume too much salt; adult Americans typically eat twice the daily amount recommended by dietary guidelines. Bread may not seem like an obvious culprit; however, due to high consumption and relatively high salt content, baked goods are a major source of sodium in the diet. A new study from the explores ways to reduce sodium in bread without sacrificing taste and leavening ability. |
| Researchers identify mutations of Delta, Delta Plus variants Posted: 28 Sep 2021 12:51 PM PDT Using bioinformatics tools and programming, researchers identified five specific mutations that are far more prevalent in Delta Plus infections compared to Delta infections, including one mutation, K417N, that is present in all Delta Plus infections but not present in nearly any Delta infections. The findings provide important clues to researchers about the structural changes to the virus recently and highlight the need to expand the toolbox in the fight against COVID-19. |

| There’s no place like home…to track blood pressure Posted: 28 Sep 2021 07:22 AM PDT Adults with elevated blood pressure who had not been diagnosed with high blood pressure found that monitoring their blood pressure at home was more acceptable than going to a kiosk, clinic or using a 24-hour wearable monitoring device. Adults were more likely to record the minimum number of measurements with at-home or clinic-based blood pressure monitoring versus going to a kiosk. Adults found the 24-hour wearable blood pressure measuring device least acceptable among the options. Health care professionals should consider talking with people who have high blood pressure about the option of home monitoring and providing the tools and education necessary to do it correctly. |
| Microscopic metavehicles powered by nothing but light Posted: 28 Sep 2021 04:50 AM PDT Researchers have succeeded in creating tiny vehicles powered by nothing but light. By layering an optical metasurface onto a microscopic particle, and then using a light source to control it, they succeeded in moving the tiny vehicles in a variety of complex and precise ways -- and even using them to transport other objects. |
