New study says rainwater is now unsafe to drink

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

A new study says that changing guidelines for forever chemicals have made rainwater all around the world unsafe to drink.


Rainwater is an important part of our planet’s ecosystem, and it helps fuel access to drinking water in many places. However, a new study suggests that rainwater is now unsafe to drink. The study says that “forever chemicals” have reached unsafe levels. These forever chemicals are scientifically known as per-and poly-fluoroalkyl substances (PFAS), and they don’t break down in the environment.

You can find PFAS chemicals in non-stick and stain-repellent properties. As such, they’re found in a lot of household food packages, electronics, and even cosmetics and cookware. However, it seems that these chemicals are now mixing with our rainwater. As a result, it has made rainwater unsafe to drink. And researchers say they can’t tie this issue to just one location. It’s everywhere in the world, even in Antarctica.

Saving water with wireless technologies is possible — but there are challenges

Posted by in categories: food, internet, robotics/AI, sustainability, wearables

Water is the most essential resource for life, for both humans and the crops we consume. Around the world, agriculture accounts for 70% of all freshwater use.

I study computers and information technology in the Purdue Polytechnic Institute and direct Purdue’s Environmental Networking Technology (ENT) Laboratory, where we tackle sustainability and environmental challenges with interdisciplinary research into the Agricultural Internet of Things, or Ag-IoT.

This parasite makes you more attractive so you’ll have sex and spread it, strange study says

Posted by in categories: energy, food, sex

Toxoplasma gondii (T.gondii) is a common parasite, one that scientists say may infect more than half the world’s population. Now, scientists also believe that T.gondii may be manipulating its hosts to make them more attractive to others. If true, it means there may be a parasite out there that makes people more attractive to fuel its spread to new hosts through sexual activity.

Parasites have always been known to influence the way their hosts behave when trying to move to a new host. T.gondii itself has been known to manipulate its hosts. Researchers previously discovered that the parasite could make infected rats attracted to the smell of urine from predator cats. This led the rats to take part in riskier behavior. As a result, the likelihood of a cat eating the rat increased dramatically.

This allowed the parasite to move on to its optimal host. Once it has reached that optimal host, though, the parasite can then reproduce sexually. What’s most terrifying about how this parasite works is that the manipulation doesn’t stop there. Instead, similar manipulations have been seen in chimpanzees, hyenas, and humans, too. If the parasite can make people more attractive, it could spread more easily.

A New York farm is making a bacon substitute from mycelium. Pigs are happy.


MyForest Foods is harvesting 1.3 million kilos of “bacon” made from mycelium. It is one of a number of growing uses for this fungus.

Bad Things Happen After Dark

Posted by in categories: biological, food, neuroscience

You might identify with the Mind After Midnight hypothesis if you’ve ever stayed up late angrily commenting on Twitter posts, finishing another bottle of wine, eating a whole pint of ice cream out of the container, or just feeling miserable.

The hypothesis suggests that when humans are awake during the biological circadian night—after midnight for most people—there are neurophysiological changes in the brain that alter the way we interact with the world, especially actions related to impulse control, reward processing, and information processing. The hypothesis was detailed in a recent paper published in the journal Frontiers in Network Psychology.

“There are millions of people who are awake in the middle of the night, and there’s fairly good evidence that their brain is not functioning as well as it does during the day.” —

How artificial intelligence can make our food safer

Posted by in categories: food, robotics/AI

Food recalls could be a thing of the past if artificial intelligence (AI) is utilized in food production, according to a recent study from UBC and the University of Guelph.

The average cost of a food recall due to bacterial or microbial contamination, like E. coli, is US$10 million according to study co-author Dr. Rickey Yada, a professor and the dean of the UBC faculty of land and .

We spoke with Dr. Yada about how AI can help optimize the current systems used in the industry, and how it can help make our safer.

This lab-grown cooking oil could replace vegetable oil

The challenge: Just 100 years ago, vegetable oils were practically nonexistent in the human diet. Today, they’re a major part of it: 740 million acres — an area that would cover 90% of India — are dedicated to growing soybeans, palm trees, and other oilseed crops.

While these cooking oils can make food extra tasty, oilseed crop production releases greenhouse gasses, contributes to biodiversity loss, and consumes freshwater that could otherwise be used for drinking or to grow other food.

Scientists Identify Cover Crops That Keep Nitrogen in Soil

Posted by in categories: biological, food

From Alice in Wonderland to The Lord of the Rings, our stories have long depicted magical worlds hidden underground. Yet the most magical account of all might turn out to be reality, as scientists reveal a complex network of reactions between plants, fungi, bacteria, and more, interacting below the soil surface to support the foundations of life. At USDA’s Agricultural Research Service, one part of the research into this intricate underground world involves identifying techniques that will keep nitrogen—a vital element for plant growth—in the soil.

Like all good stories, this one has heroes and villains whose actions can wreak havoc or save us. When properly sequestered underground, some forms of nitrogen like ammonium and nitrate perform heroic feats, fertilizing the plants that we depend on for our food. Yet when they escape the soil in the wrong ways, they morph into closely-related super-villains malignant forms of nitrogen like nitrous oxide that, in the atmosphere, is 300 times more powerful than carbon dioxide in trapping heat, and lingers far longer. In fact, N2O is the largest source of greenhouse gas from agriculture. Escaped nitrogen can also get into groundwater or run off fields and into waterways; once there, it can fuel algae blooms in coastal waters that consume oxygen, harming fish and other aquatic creatures.
