Indoor and Vertical Farming May Be Part of the Solution to Rising Demands for Food and Limited Natural Resources
"Imagine walking into your local grocery store on a frigid January day to pick up freshly harvested lettuce, fragrant basil, juicy sweet strawberries, and ripe red tomatoes – all of which were harvested at a local farm only hours before you’d arrived. You might be imagining buying that fresh produce from vertical farms where farmers can grow indoors year-round by controlling light, temperature, water, and oftentimes carbon dioxide levels as well. Generally, fresh produce grown in vertical farms travels only a few miles to reach grocery store shelves compared to conventional produce, which can travel thousands of miles by truck or plane." more »
National Institutes of Health: COVID-19 Vaccines Linked to Small Increase in Menstrual Cycle Length
"The team found that women who received a COVID-19 vaccine had an average increase in cycle length of nearly one day for each dose. Among women who received a two-dose vaccine, the first dose was associated with a 0.71-day increase in cycle length and the second dose with a 0.91-day increase. After adjustment for age, race and ethnicity, BMI, education, and other factors, the change in cycle length was still less than one day for each dose. Receiving two vaccine doses within the same menstrual cycle increased the cycle length further — about two days on average. Women’s cycle lengths often fluctuate, and experts consider cycle variation of up to eight days to be normal. The longer menstrual cycles after vaccination decreased in subsequent cycles, suggesting they are likely temporary." more »
Ferida Wolff's Backyard: Squirrel On Ice
Ferida Wolff Writes: I know it’s winter and it’s not unexpected but I realize that our outdoor critters are not as lucky as we are to have a warm place to shelter in. I hope that Mother Nature will be kind and help all her critters, even us, have a healthy winter. But we aren’t the only ones affected by the cold weather. Today a squirrel was trying to get a drink on the birdbath but the water was frozen over. (Adding a birdbath to your yard is the easiest way to provide drinking and bathing water for birds.) more »
GAO Reports - Disaster Recovery: School Districts in Socially Vulnerable Communities Faced Heightened Challenges After Recent Natural Disasters
Most school districts that received key federal disaster recovery grants following 2017-2019 presidentially-declared major disasters had elevated proportions of students from certain socially vulnerable groups, according to GAO's analysis of federal data. Research shows that socially vulnerable groups — including children who are low income, minorities, English learners, or living with disabilities — are particularly susceptible to the adverse effects of disasters. School districts serving high proportions of children in these groups may need more recovery assistance compared to districts with less vulnerable student populations. The Federal Emergency Management Agency's (FEMA) Public Assistance program and the Department of Education's Immediate Aid to Restart School Operations (Restart) program may provide such assistance. GAO found that 57 percent of school districts receiving these key grants for 2017-2019 disasters served a higher than average proportion of students in two or more of these socially vulnerable groups, compared to 38 percent of all school districts nationwide. more »
