A study published in the Journal of Neuroscience found evidence that artificial dog breeding has affected the animal’s brain.

Artificial dog breeding has been around for centuries, even notably performed by George Washington and the crossbreed of the American foxhound. Selective breeding is done to achieve desired behavioral and physical characteristics. A study at Harvard University set out to find out if the practice has affected their physical characteristics in ways we can’t see. 

Dr. Erin Hecht, the leader of the study, focused on brain structure unrelated to body size or head shape. 62 male and female dogs of 33 different dog species were given MIRS. After the areas of the brains were analyzed, the team created six separate brain network models, each related to a different behavior specialization like hunting, guarding, companionship, etc. An analyzation of the data revealed that brain anatomy has significant variation among the different dog species, likely related to human-applied selection for behavior. 

This study is one of the first related to the complications of selective breeding and Dr. Hecht, and their team, look forward to continuing their research.

Currently, 92% of Clorox’s packaging is recyclable but new goals set by the company will aim to make 100% of their packaging recyclable or compostable by 2025 and reduce half of the virgin plastic and paper-based fiber by 2030. In the United States and Canada, they aim for their buildings to be 100% renewable electricity. To increase transparency, the company has also agreed to publish a list of “restricted substances.”

In 2018, only 4% of corporate sustainability goals were met. To ensure success, Clorox is attaching executive pay to their sustainability targets, meaning executives who reach these goals will receive bonuses. Benno Dorer, chairman and CEO at Clorox said, “As a mission-driven company, it’s important for us to continue integrating ESG [environmental, social and governance] into our overall business strategy.”

EPA announced a ​new proposal to update the Lead and Copper Rule

After nearly 30 years of a stagnant Lead and Copper Rule, the Environmental Protection Agency announced a new proposal to update the regulation. The new regulations are aimed to increase lead identification, sampling, and strengthen treatment by increasing the number of hours a service provider needs to notify a customer that their water is contaminated with lead.

The Natural Resources Defense Council and other environmental activists have expressed concern that the new regulation allows communities more to time to replace the lead service lines, indicating these regulations may be weaker than the previous. The new proposal also establishes a lower “trigger level” of lead to 10 parts per billion from 15 parts per billion. The main counterargument is health experts have never established that any level of lead can be sustainable. “Even low levels of lead can cause harm to developing brains and nervous systems, fertility issues, cardiovascular and kidney problems, and elevated blood pressure. Pregnant women and children are particularly vulnerable,” the NRDC said in a statement.

The last major lead pipe exposure in Iowa outbreak was December 2016. More than 6,000 Iowans were exposed to contaminated water for over six months. The issue brought up major incongruency in the method to solve the problem between University of Iowa engineers or Iowa Departments of Public Health and Natural Resources.

Iowa Climate Statement 2019: Dangerous Heat Events to Become More Frequent and Severe


Kasey Dresser and Tyler Chalfant | October 7, 2019

Just weeks after July 2019 became the hottest month in 140 years of recordkeeping, 216 science faculty and researchers from 38 Iowa colleges and universities have endorsed the ninth annual Iowa Climate Statement 2019: Dangerous Heat Events to Become More Frequent and Severe.

The statement, released on September 18, warns Iowans and Midwesterners of sobering extreme heat projections for the region. Based on the most up‐to‐date scientific sources, the statement makes clear the urgency of preparing for dangerously hot summers in the coming decades.

Betsy Stone, Associate Professor in the Department of Chemistry at the University of Iowa, reads this year’s statement in the video above. Access the full written statement here.

Veggie Rx coming to Johnson County

A $50,000 grant from MidWestOne Bank has been awarded to Johnson County community organizations for the creation of the Veggie Rx Pilot Program. This 26-week program aims to help individuals with diet-related diseases by providing them with fresh fruits and vegetables.

Participants of the program will receive care from the University of Iowa Health Care’s upstream clinic and their food from either the Coralville or North Liberty Community Food Pantry. With routine access to locally grown fresh fruits and vegetables, individualized dietary guidance, and educational activities related to healthy food, the participants will hopefully see positive changes in their daily life. Food will be purchased directly from Sundog Farm in Solon, Wild Woods in Iowa City, and Echollective in Mechanicsville.

MidWestOne Bank CEO Charlie Funk said the bank was “delighted to lend support to the Veggie Rx Program,” which will give back not only to local residents but provide business to local farms as well.

Why is action on climate change more important than ever before?


Kasey Dresser| September 19, 2019

The Iowa Climate Statement 2019: Dangerous Heat Events to Become More Frequent and Severe was released yesterday at press conferences in Des Moines and Cedar Rapids.

Yesterday, at the Cedar Rapids Press Conference, Dr. Jerry Schnoor was asked what he would say to individuals that do not currently see climate change as a major issue. 

This year’s statement warns Iowans and Midwesterners of sobering extreme heat projections for the region. Based on the most up-to-date scientific sources, the statement makes clear the urgency of preparing for dangerously hot summers in coming decades.  The statement describes some of the sobering impacts of hotter heat waves and more hot days. The 9th annual Iowa Climate Statement was endorsed by a record 216 science faculty, researchers and educators from 38 Iowa colleges and universities.
