Tectonic Activity Shakes Geologists
Long considered to be geologically inactive, our 4.6billion-year-old moon is showing signs of tectonic activity via seismometers deployed between 1969 and 1972 during the NASA Apollo program. Although some “moonquakes” have been recorded near cliff-like fault scarps on the surface, they may be caused by the irregular gravitational effects of orbiting the more massive Earth or extreme temperature differences created by sunlight in the vacuum of space. Employing more sensitive equipment has been proposed for future missions to assist in choosing potential colonization sites. 10
Climate change has inspired farmers to turn to regenerative agriculture, which pulls carbon dioxide out of the atmosphere and stores it in their soil. Regenerative agriculture incorporates the practices of planting trees, cover cropping, no-till farming and rotational grazing. As the groundswell of support grows, 250 soil health bills have been introduced in state and federal legislatures in the last two years. At a U.S. Senate Agriculture Committee climate change hearing, Nebraska soybean farmer Matthew Rezac said that keeping soil healthy, not just reducing greenhouse gas emissions, was a key part of what farmers could do to cool a warming planet. According to the Union of Concerned Scientists, the bills have different justifications, but they all focus on soil health. As disastrous floods and drought sweep away farmland, the idea that regenerative agriculture could make for more productive farming is gaining traction.
Artificial Light Tied to Inflammation Fluorescent lighting is one of the most common sources of artificial light, but new research from Texas State University suggests there may be unexpected consequences at the genetic level. Team member Ronald B. Walter says, “Over the past 60 years, we have increasingly relied on artificial light sources that emit much narrower wavelength spectrums than does the sun. Yet, little research has been conducted to determine gene expression consequences, if any, from use of common artificial light sources.” Their findings, published in the online journal Genes, show increased inflammation in tissue and organs and increased immune response in the subject animals, regardless of whether the species is primarily active in the day or night.
Farmers Responding to Climate Change
Critical habitat is threatened for 12 coral species in Florida, the Caribbean and the Pacific Ocean, while all corals worldwide are experiencing dramatic declines due to the impacts of climate change, pollution and overfishing. The Center for Biological Diversity, a Tucson-based nonprofit focused on species protection, intends to file a lawsuit against the federal government for failing to protect coral habitat as required under the Endangered Species Act. Benefits of securing a critical habitat designation from the National Marine Fisheries Service include improved water quality throughout the coastal zone, limits on overfishing, protection of spawning grounds, reduced impact from development and dredging, and reduced human pressures on thousands of species that inhabit the reefs. Nearly 30 percent of all corals have already been lost to warming ocean temperatures and ocean acidification due to greenhouse gas pollution; scientists predict that the rest could be gone by the end of the century without help.
