Most US pet food contaminated with ‘forever chemicals’, study finds

Posted by in categories: biotech/medical, chemistry, food, health

“This represents a significant source of PFAS in the home environment,” said Sydney Evans, a science analyst with the EWG.

PFAS, or per-and polyfluoroalkyl substances, are a class of about 12,000 compounds used to make products resist water, stains and heat. They’re called “forever chemicals” because they don’t naturally break down, accumulating in humans and animals. PFAS are linked to a range of serious health problems like cancer, birth defects, kidney disease and liver disease.

The chemicals are likely used in pet food bags to make them repel grease. For cats, the highest levels were detected in the Meow Mix Tender Centers salmon and chicken flavors dry cat food, at more than 600 parts per million (ppm). Purina Cat Chow Complete chicken showed over 350 ppm, while Blue Buffalo, Iams and Rachael Ray Nutrish all had levels of less than 100 ppm.

Eat This Drone

Posted by in categories: drones, food

Most delivery drones can only carry about one-third of their mass as payload, because most of their mass is both critical, like wings, and comes in the form of things that are essentially useless to the end user, like wings. But EPFL researchers have invented a drone with wings made from rice cakes.

Study involving CU-Boulder shows fertilizer can be made from sunlight

Posted by in categories: biological, chemistry, food, particle physics

A group of scientists led by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) in Golden and involving the University of Colorado Boulder has developed a new, eco-friendly method to produce ammonia, the main ingredient of fertilizer, using light.

The researchers discovered that light energy can be used to change dinitrogen (N2), a molecule made of two nitrogen atoms, to ammonia (NH3), a compound of nitrogen and hydrogen. The researchers hope the newly discovered, light-driven chemical process that creates ammonia can lead to future developments that will enhance global agricultural practices while decreasing the dependence of farmers on fossil fuels.

Traditionally there have been two main ways to transform nitrogen, the most common gas in Earth’s atmosphere, for use by living organisms. One is a biological process that occurs when atmospheric nitrogen is “fixed” by bacteria found in the roots of some plants like legumes and then converted to ammonia by an enzyme called nitrogenase.

Bumble bees like to ‘play’: new video study shows them moving balls for fun

Posted by in categories: food, robotics/AI

So even insects like to play and have fun.


Bumble bees enjoy playing with balls, suggesting insect minds are far more sophisticated than previously thought, researchers have found.

Study shows hazardous herbicide chemical goes airborne

Posted by in categories: chemistry, engineering, food

“Dicamba drift”—the movement of the herbicide dicamba off crops through the atmosphere—can result in unintentional damage to neighboring plants. To prevent dicamba drift, other chemicals, typically amines, are mixed with dicamba to “lock” it in place and prevent it from volatilizing, or turning into a vapor that more easily moves in the atmosphere.

Now, new research from the lab of Kimberly Parker, an assistant professor of energy, environmental and chemical engineering at Washington University in St. Louis’ McKelvey School of Engineering, has shed new light on this story by demonstrating for the first time that these themselves volatilize, often more than dicamba itself.

Their findings were published Sept. 23 in the journal Environmental Science and Technology.

Carbon dioxide can revolutionize rooftop farming, here is the proof

Posted by in categories: food, sustainability

A new way to boost the growth of plants in rooftop farms.

Humans constantly breathe out large amounts of CO2 and when we are inside a building for a period of time, it creates high concentrations of carbon dioxide inside the building. This CO2 is removed through a building’s exhaust system.
