#1- Expat Eddie outlines a few of his own pointed Latin learning experiences as a gringo boss, including interviewing, hiring, firing, managing and training Latin workers. #2- When gringos get into car accidents. What if a gringo didn’t know Spanish, had an expired driver’s license and no insurance. On top of that, what if he totaled the other guy’s car, …
Katharyn Boyer’s work is focused on the ecology and restoration of coastal habitats, primarily salt marshes and seagrass beds. She is particularly interested in how species interact to structure their environments and influence fundamental ecosystem processes such as nutrient cycling. Such basic ecological research has important implications for the restoration of damaged habitats. Today we talk about seagrasses. Download this …
The risk of flooding in the United States is changing regionally, and the reasons could be shifting rainfall patterns and the amount of water in the ground. In a new study, University of Iowa engineers determined that, in general, the threat of flooding is growing in the northern half of the U.S. and declining in the southern half. The American …
On August 9, 1967, a 5.5 magnitude earthquake struck Northglenn, a northern suburb of Denver, Colorado. The Associated Press wrote that it was “the severest earthquake ever recorded” in the city’s history. Building foundations cracked, windows broke, bricks flew off of downtown rooftops. A year later in the prominent academic journal “Science,” geophysicist J.H. Healy and his associates proposed that …

Photo credit: DB Marsh/Library and Archives Canada via Flickr The researchers report in the Journal of Remote Sensing that examination of 87,000 images captured by the NASA Landsat satellite reveals that Alaska, Quebec and other regions became greener between 1984 and 2012. Landsat, a project also backed by the U.S. Geological Survey (USGS), provides the …
The director of the Southern California Earthquake Center, Thomas Jordan, made an announcement recently that would have sent a chill down the spine of every Californian: that the San Andreas fault appears to be in a critical state and as such, could generate a large earthquake imminently. Of course, the reiteration of the seismic hazard to Californians will be nothing surprising, …
The U.S. Environmental Protection Agency (EPA) has released its first-ever analysis on the effects of three common pesticides—chlorpyrifos, diazinon and malathion—on endangered and threatened species and designated critical habitat nationwide. The resounding conclusion? Pesticides are terrible for them. According to the report, malathion and chlorpyrifos harms an astounding 97 percent of the 1,782 animals and plants protected under the Endangered Species Act. Diazinon harms 79 percent. Malathion is often used on fruit, vegetables …
Oil and gas drilling has made parts of the central United States as dangerous as the most earthquake-prone regions of California, according to the U.S. Geological Survey (USGS), exposing millions of people to the risk of human-induced earthquakes, known as “frackquakes.” According to new maps released on Monday by the USGS, roughly 7 million people who live and work in parts of …
A new study (abstract below) has found that the monarch butterfly population in the US has “a substantial probability of quasi-extinction, from 11–57% over 20 years”. The study repeats the well-documented fact that a major factor in the decline of the monarch is the adoption of herbicide-tolerant GM corn and soybeans. The herbicide spraying has killed off the monarch larvae’s only food, …
PARIS, 9 December, 2015 – Some of the world’s coldest places, on land and sea, may be plunged into an unstoppable transition to a climate system most scientists believe has not existed for 35-50 million years. The almost immediate consequences would include the loss of reliable water resources for millions of people, and the start of a process leading to …
