Smoking risk drops significantly in college graduates when they live near areas that completely banned smoking in bars and restaurants, according to a new Drexel University study published in the American Journal of Epidemiology.

A protein involved in cognition and storing long-term memories looks and acts like a protein from viruses. The protein, called Arc, has properties similar to those that viruses use for infecting host cells, and originated from a chance evolutionary event that occurred hundreds of millions of years ago.

When babies crawl, their movement across floors, especially carpeted surfaces, kicks up high levels of dirt, skin cells, bacteria, pollen, and fungal spores, a new study has found. The infants inhale a dose of bio bits in their lungs that is four times (per kilogram of body mass) what an adult would breathe walking across the same floor.  

A paper appearing in Geophysical Research Letters uses machine learning to craft an improved model for understanding geothermal heat flux — heat emanating from the Earth’s interior — below the Greenland Ice Sheet. It’s a research approach new to glaciology that could lead to more accurate predictions for ice-mass loss and global sea-level rise.

One of the most puzzling questions in breast cancer research is why some tumors stay put, while rogue cells from others break free and spread to surrounding tissues, the first step toward creating a more lethal disease. Although researchers have found some signs in mutated genes or telltale proteins on the cell’s surface, those discoveries don’t tell the whole story.

Paulette McIlvena went to bed, at home, and woke up three weeks later, in hospital. She became severely ill due to complications from pancreatitis. While she was in a coma McIlvena underwent surgery and was put on dialysis as a temporary measure. Following those events in 2004, the pancreatitis cleared up, McIlvena’s kidneys started working again, and she thought her kidney troubles were behind her.

Recently, however, she was diagnosed with chronic kidney disease related to her experience 13 years ago and is now being treated by UCalgary’s Cumming School of Medicine physician-scientist Dr. Matthew James.

In urban streams, persistent pharmaceutical pollution can cause aquatic microbial communities to become resistant to drugs. So reports a new study published today in the journal Ecosphere. 

A team of scientists at the Keck School of Medicine of USC is looking to some deep sea dwellers to create a better way to develop cancer-fighting therapies. Harnessing the power of the enzymes that give these marine animals the ability to glow, the team created a test that makes it easy for researchers to see whether a therapy is having its intended effect — killing cancer cells. The results of their study were published in Scientific Reports Jan. 9.

A University of Victoria molecular biologist has gained new insights into how environmental contaminants may disrupt thyroid systems. The discovery was made while assembling the genome of the North American bullfrog.

Caren Helbing’s findings could help explain the mechanisms of early development, as well as how environmental contaminants cause thyroidrelated diseases and malfunctions.

An old drug supercharged by University of Queensland researchers has emerged as a new antibiotic that could destroy some of the world’s most dangerous superbugs.
