An often-overlooked water plant that can double its biomass in two days, capture nitrogen from the air—making it a valuable green fertilizer—and be fed to poultry and livestock could serve as life-saving food for humans in the event of a catastrophe or disaster, a new study led by Penn State researchers suggests.

Native to the eastern U.S., the plant, azolla caroliniana Willd—commonly known as Carolina azolla—also could ease food insecurity in the near future, according to findings recently published in Food Science & Nutrition. The researchers found that the Carolina strain of azolla is more digestible and nutritious for humans than azolla varieties that grow in the wild and also are cultivated in Asia and Africa for livestock feed.

The study, which was led by Daniel Winstead, a research assistant in the labs of Michael Jacobson, professor of ecosystem science and management, and Francesco Di Gioia, assistant professor of vegetable crop science, is part of a larger interdisciplinary research project called Food Resilience in the Face of Catastrophic Global Events conducted in the College of Agricultural Sciences.

The Cocoa Press isn’t an easy 3D printer — but how many let you eat the results?

I hate to be the bearer of bad-for-the-waistline news, but yes — you can now buy a 3D printer that prints chocolate.

The Cocoa Press is a 3D printer that prints chocolate. It costs $1,499 as a DIY kit, and $3,995 prebuilt. It’s shipping now.

The cultivation of triploid genetics could be the game changer for the cannabis industry, as it promises to deliver higher THC levels, larger yields, faster growth, and seedless flowers.

The application of triploids is not a new concept in agriculture. Consuming seedless fruit generally enhances the eating experience for most people.

Consider bananas, for instance. Bananas lack seeds because the parent banana tree is triploid, even though pollination normally occurs.

Studies show that physical activity is actually a mental health exercise. One article that states just 15 minutes of walking, especially in the out-of-doors, can boost mood and reduce feelings of depression.

People seem to think more clearly after a brisk walk as well. It makes sense. As the heart pumps oxygen and nutrients to working muscles, the brain gets the same benefits.

Are there foods that might help our brains stay focused? In 2015, scientists reported on a diet that was found to help slow the gradual decline in cognitive function we may experience as we age. It was a hybrid of the Mediterranean diet and the DASH diet (Dietary Approaches to Stop Hypertension) cutely named the MIND diet (Mediterranean-DASH Diet Intervention for Neurodegenerative Delay).

In a study published last month in mSystems, researchers from Osaka University revealed that the interaction between two common types of oral bacteria leads to the production of a chemical compound that is a major cause of smelly breath.

Bad breath is caused by volatile compounds that are produced when bacteria in the mouth digest substances like blood and food particles. One of the smelliest of these compounds is methyl mercaptan (CH₃SH), which is produced by microbes that live around the teeth and on the surface of the tongue. However, little is known about which specific bacterial species are involved in this process.

“Most previous studies investigating CH₃SH-producing oral bacteria have used isolated enzymes or relatively small culture volumes,” explains lead author of the study Takeshi Hara. “In this study, we aimed to create a more realistic environment in which to investigate CH₃SH production by major oral bacteria.”

Researchers in South Korea injected grains of rice with cow muscle and fat cells to create something being called beef rice. This pink-colored substance could offer a cheaper and more sustainable protein source than standalone meat.

Is there a connection between cannabis use and binge eating? This is what a recent study published in Experimental and Clinical Psychopharmacology hopes to address as a team of researchers investigated the medical risks associated with cannabis use and binge eating, specifically the link between the two. This research marks only the third study conducted to make a connection between cannabis use and binge eating disorder and holds the potential for scientists, medical practitioners, and patients make better informed clinical decisions for treating binge eating.

“Distinguishing the relationship between cannabis use, eating disorder severity and other psychiatric symptoms in binge eating patients is necessary for informing screening and clinical recommendations,” said Megan Wilkinson, who is a PhD student in Drexel University’s College of Arts and Sciences and lead author of the study.

For the study, the researchers enlisted 165 participants who were pursuing medical treatment for binge eating and were asked to report both their cannabis and alcohol use as part of the survey. In the end, the researchers found that 23 percent of the participants had used cannabis within the prior three months. Additionally, the participants were also found to have increased alcohol consumption, as well. In terms of the connection between cannabis use and binge eating, while the researcher concluded that cannabis use did not result in increased binge eating, they found the opposite in that binge eating could result in increased cannabis use, as noted by the 23 percent participants who reported using cannabis.
