Norovirus appears to be spreading as rate of positive tests spikes

Norovirus is sometimes referred to as the stomach flu, but it is not related to the influenza virus. Rather, it is a highly contagious virus that typically causes gastrointestinal symptoms like diarrhea, vomiting, nausea and stomach pain. Mild fever and aches are possible, too.

Just a few virus particles are enough to make someone sick, and they spread easily via hands, surfaces, food and water. An infected person can transmit the virus for days after they’re feeling better, potentially even up to two weeks, according to the CDC.

Regionally, the Midwest had the highest average test positivity rate for norovirus as of Saturday, at over 19% — higher than any other week in the last year.

Compound in Mushrooms Discovered To Magnify Memory

Researchers from The University of Queensland have discovered the active compound from an edible mushroom that boosts nerve growth and enhances memory.

Professor Frederic Meunier from the Queensland Brain Institute said the team had identified new active compounds from the mushroom, Hericium erinaceus. This type of edible mushroom, commonly known as the Lion’s Mane Mushroom, is native to North America, Europe, and Asia. It is commonly sought after for its unique flavor and texture, and it is also used in traditional Chinese medicine to boost the immune system and improve digestive health.

Researchers have discovered lion’s mane mushrooms improve brain cell growth and memory in pre-clinical trials.

Can trees talk to each other with fungal networks? Study raises doubts

A new literature review of papers on “common mycorrhizal networks” seems to indicate the science behind them is not as strong as once thought.

Akin to the Ents from “The Lord of the Rings,” there is an idea in modern botany that trees can “talk” to one another through a delicate web of fungus filaments that grows underground. The idea is so alluring that it has gained traction in popular culture and has even been termed the “wood-wide network.”

However, according to Justine Karst, associate professor from the University of Alberta’s Faculty of Agricultural, Life, and Environmental Sciences, it could all be nonsense.

“It’s great that CMN research has sparked interest in forest fungi, but it’s important for the public to understand that many popular ideas are ahead of the science,” says Karst.

Farming robot kills 200,000 weeds per hour with lasers

In 2021, Carbon Robotics unveiled the third-generation of its Autonomous Weeder, a smart farming robot that identifies weeds and then destroys them with high-power lasers. The company now has taken the technology from that robot and built a pull-behind LaserWeeder — and it kills twice as many weeds.

The weedkiller challenge: Weeds compete with plants for space, sunlight, and soil nutrients. They can also make it easier for insect pests to harm crops, so weed control is a top concern for farmers.

Chemical herbicides can kill the pesky plants, but they can also contaminate water and affect soil health. Weeds can be pulled out by hand, but it’s unpleasant work, and labor shortages are already a huge problem in the agriculture industry.

Lifespan Record Broken In E5 Study

This has been the news lately. This is a good breakdown of info and apparently Katcher wishes to do dog trials.


In this video we provide a quick update on activities at Yuvan Research. It is very exciting to see that Sima, the last remaining rat in the E5 trial is still alive and has surpassed the age of the previous record for lifespan of a Sprague Dawley rat.
