Scientists Discover a Dynamic Cellular Defense Against Breast Cancer Invasion

Johns Hopkins Medicine

Johns Hopkins researchers report they have demonstrated in mouse tissue grown in the lab that the cell layer surrounding breast milk ducts reaches out to grab stray cancer cells to keep them from spreading through the body. The findings reveal that this cell layer, called the myoepithelium, is not a stationary barrier to cancer invasion, as scientists previously thought, but an active defense against breast cancer metastasis.

Do Obese Patients Have a Higher Risk of Infection and Dying After Colon Surgery?

Diseases of the Colon and Rectum Journal

In a study published in the August issue of Diseases of the Colon & Rectum, investigators from the University of Alabama at Birmingham sought to answer this question. While it has been long recognized that heavy patients are at higher risk of complications after surgery, Dr. Wahl and his colleagues wanted to find out whether there was a difference whether a patient was merely pudgy or downright obese.

Opioids and Older Adults: Poll Finds Support for Prescribing Limits, and Need for Better Counseling and Disposal Options

Michigan Medicine - University of Michigan

Nearly a third of older adults have received a prescription for an opioid pain medicine in the past two years, but a new poll shows many didn’t get enough counseling about the risks that come with them, how to reduce use, when to switch to a non-opioid, or what to do with leftovers. Nearly three-quarters support limits on how many opioids a doctor can prescribe at once.

WVU Experts Are Available to Talk About Food-Safety Regulations and How to Prevent Foodborne Illnesses

West Virginia University

West Virginia University expert Simon Haeder says the massive increases in food recall over the last five years-- 92.7 percent for the U.S. Food and Drug Administration and 83.4 percent for the U.S. Department of Agriculture (according to a study by the Stericycle Recall Index)-- could be attributed to alterations in agency regulations. Another WVU expert, Jacek Jaczynski, said it’s simple to avoid illness by washing hands and thoroughly cooking food.

WVU Expert Says Water on Mars Would Be Extremely Acidic but Could Host Life

West Virginia University

With new and compelling evidence for water existing beneath the south pole of Mars, a West Virginia University professor says this underground lake is likely to be extremely salty and more acidic than battery acid. Life forms that can survive in extreme physical and geochemical conditions are found in abundance in acid salt lakes such as those in Chile and western Australia, she said.

Enduring ‘Radio Rebound’ Powered by Jets From Gamma-Ray Burst:

National Radio Astronomy Observatory

Astronomers using ALMA studied a cataclysmic stellar explosion known as a gamma-ray burst, or GRB, and found its enduring “afterglow.” The rebound, or reverse shock, triggered by the GRB’s powerful jets slamming into surrounding debris, lasted thousands of times longer than expected. These observations provide fresh insights into the physics of GRBs, one of the universe’s most energetic explosions.

Saturn and Mars Team Up to Make Their Closest Approaches to Earth in 2018

Space Telescope Science Institute (STScI)

NASA’s Hubble Space Telescope has photographed Saturn and Mars near their closest approaches to Earth in June and July 2018. It’s now summertime in Saturn’s northern hemisphere and springtime in Mars’ southern hemisphere. The Hubble images show that Earth isn’t the only planet where intense spring and summer storms wreak havoc.

Bacterial Communities Use Sophisticated Strategy to Communicate over Long Distances

University of California San Diego

“Percolation” theory is helping explain how communities of bacteria can effectively relay signals across long distances. Once regarded as simple microorganisms, communities of bacteria have been found to employ a strategy we use to brew coffee and extract oil from the sea. Percolation helps the microscopic community thrive and survive threats.
