BALTIMORE, MD, May 13, 2025 – As communities across the United States continue to confront the devastating toll of mass shootings, new research reveals a staggering economic dimension to these tragedies. A study published in the INFORMS journal Marketing Science finds that mass shootings cause an estimated $27 billion in annual lost revenue for U.S. retailers driven by sharp declines in foot traffic, reduced transaction volume and long-term store closures.
BALTIMORE, MD, May 13, 2025 – Researchers who took a close look at loosened concealed carry laws between 2010 and 2017 have found that “Shall Issue” regulations, which remove local authority discretion on the issuance of concealed carry gun permits, contribute to a significant increase in handgun purchases. At the same time, the researchers found that in states that adopted “Permitless Carry” policies, there was no noticeable change in gun purchases.

The development of a COVID-19 vaccine is at the forefront of everyone’s minds. Recent news suggests that a solution may be available in 2021, though the hope is sooner. The race for a vaccine adds to a body of evidence that suggests when under pressure the pharmaceutical industry reacts quickly.
When it comes to COVID-19, what happens in Vegas doesn’t stay in Vegas. Las Vegas casinos reopened June 4, and they have become a likely hotbed for the spread of the novel coronavirus, public health experts said. But if tourists return home and then test positive for COVID-19, the limitations of contact tracing in the midst of a pandemic make it unlikely such an outbreak would be identified.
A vaccine for the coronavirus that causes covid-19 appears to be our best strategy to ending the current pandemic. Unfortunately, the fastest time frame in which scientists have managed to create any vaccine in history was four years, and there’s already plenty of skepticism surrounding the safety, availability, and effectiveness of any future covid-19 inoculation. So let’s go over the most pressing questions.
Thank you very much for the excellent article, “Get your flu shot!” Aug. 16, page A1, with the interview with Dr. Mark Kenton, who is urging that we get a flu shot this year, due to the Covid-19 pandemic. I agree that this is imperative not only for our community’s health but also to try to limit the demands for healthcare resources during what will certainly be very challenging fall and winter seasons with students returning to our towns and with still many unknowns about the coronavirus.
