Weed-killing robot is 20 times faster than humans

Posted by in categories: food, robotics/AI

The Autonomous Weeder, developed by Carbon Robotics, uses a combination of artificial intelligence (AI), robotics, and laser technology to safely and effectively drive through crop fields – identifying, targeting and eliminating weeds.

Unlike other weeding technologies, the robot utilises high-power lasers to eradicate weeds through thermal energy, without disturbing the soil. This could allow farmers to use less herbicides, while reducing labour costs and improving the reliability and predictability of crop yields.

“AI and deep learning technology are creating efficiencies across a variety of industries and we’re excited to apply it to agriculture,” said Paul Mikesell, CEO and founder of Carbon Robotics. “Farmers, and others in the global food supply chain, are innovating now more than ever to keep the world fed. Our goal is to create tools that address their most challenging problems, including weed management and elimination.”

New method preserves viable fruit fly embryos in liquid nitrogen

Posted by in categories: biological, cryonics, food, genetics, life extension

Cryopreservation, or the long-term storage of biomaterials at ultralow temperatures, has been used across cell types and species. However, until now, the practical cryopreservation of the fruit fly (Drosophila melanogaster)—which is crucial to genetics research and critical to scientific breakthroughs benefiting human health—has not been available.

“To keep alive the ever-increasing number of with unique genotypes that aid in these breakthroughs, some 160000 different flies, laboratories and stock centers engage in the costly and frequent transfer of adults to fresh food, risking contamination and ,” said Li Zhan, a postdoctoral associate with the University of Minnesota College of Science and Engineering and the Center for Advanced Technologies for the Preservation of Biological Systems (ATP-Bio).

In new research published in Nature Communications, a University of Minnesota team has developed a first-of-its-kind method that cryopreserves fruit fly embryos so they can be successfully recovered and developed into adult insects. This method optimizes embryo permeabilization and age, cryoprotectant agent composition, different phases of nitrogen (liquid vs. slush), and post-cryopreservation embryo culture methods.

Farming Robot Kills 100,000 Weeds per Hour With Lasers

Posted by in categories: chemistry, food, health, robotics/AI, space

A person can weed about one acre of crops a day. This smart robot can weed 20.


Carbon Robotics has unveiled the third-generation of its Autonomous Weeder, a smart farming robot that identifies weeds and then destroys them with high-power lasers.

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.

Intermittent Fasting for Longevity: The Science Behind the Hype

Posted by in categories: biotech/medical, food, life extension, science

Mice fed every other day in another study lived, on average, 12% longer than mice fed every day, largely due to the delay of cancerous diseases.

According to the International Food Information Council’s 2020 Food and Health Survey, you most likely know someone who is practicing intermittent fasting. The survey of 1000 adult Americans found that one in ten were putting down the fork during specified periods of time, making it America’s most popular “diet.”

BREAKING NEWS! America Study Confirms That House Flies Can Carry SARS-CoV-2 Virus Up To 24 hours After Exposure And Are Potential Vectors!

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

A new study by American researchers from Kansas State University and Agricultural Research Service have alarmingly found that house flies can carry the SARS-CoV-2 coronavirus for up to 24 hours after exposure and are potential transmission vectors of the SARS-CoV-2 coronavirus!

House flies are known to transmit bacterial, parasitic and viral diseases to humans and animals as mechanical vectors. Previous studies have shown that house flies can mechanically transmit coronaviruses, such as turkey coronavirus; however, the house fly’s role in SARS-CoV-2 transmission was not explored until now. The goal of the study was to investigate the potential of house flies to mechanically transmit SARS-CoV-2.

Physics of DNA –“In Each of Us Lies a Message, Its Beginnings Lost in the Mists of Time”

Physics of DNA —“In Each of Us Lies a Message, Its Beginnings Lost in the Mists of Time” | The Daily Galaxy.


“At one time,” writes science-fiction author Dennis E. Taylor in We Are Legion (We Are Bob), “we thought that the way life came together was almost completely random, only needing an energy gradient to get going. But as we’ve moved into the information age, we’ve come to realize that life is more about information than energy. Fire has most of the characteristics of life. It eats, it grows, it reproduces. But fire retains no information. It doesn’t learn; it doesn’t adapt. The five millionth fire started by lightning will behave just like the first. But the five hundredth bacterial division will not be like the first one, especially if there is environmental pressure. That’s DNA. And RNA. That’s life.”

This Wooden Sculpture Is Twice as Old as Stonehenge and the Pyramids

Posted by in categories: evolution, food

As the Times reports, researchers have been puzzling over the age of the Shigir sculpture for decades. The debate has major implications for the study of prehistory, which tends to emphasize a Western-centric view of human development.

In 1997, Russian scientists carbon-dated the totem pole to about 9500 years ago. Many in the scientific community rejected these findings as implausible: Reluctant to believe that hunter-gatherer communities in the Urals and Siberia had created art or formed cultures of their own, says Terberger to the Times, researchers instead presented a narrative of human evolution that centered European history, with ancient farming societies in the Fertile Crescent eventually sowing the seeds of Western civilization.

Prevailing views over the past century, adds Terberger, regarded hunter-gatherers as “inferior to early agrarian communities emerging at that time in the Levant. At the same time, the archaeological evidence from the Urals and Siberia was underestimated and neglected.”

American Honey Still Contains Radioactive Fallout From Nuclear Tests Decades Ago

Posted by in categories: food, military, nuclear weapons

As expected, various samples of fruits, nuts, and other foods revealed very faint traces of cesium-137 when measured with a gamma detector, but even Kaste wasn’t prepared for what happened when he ran the same test with a jar of honey from a North Carolina farmer’s market.


Traces of radioactive fallout from nuclear tests in the 1950s and 1960s can still be found in American honey, new research reveals.
