Assisted by AI, a workforce of bees tracks pollution and boosts biodiversity

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

When Karl Wenner looks at his farm on Upper Klamath Lake in the mountains of southern Oregon, he sees a landscape in transition.

He and his partners converted part of their fields of barley into wetlands along the shore of the lake to filter runoff and protect the quality of the water that eventually flows back into the Klamath River, which empties into the Pacific on California’s coast. The project is part of a larger effort to clean up the river, remove dams and bring back salmon.

At Lakeside Farms, that transformation is being guided by a surprising source of information: the pollen collected by tens of thousands of honeybees. A Belgian start-up called BeeOdiversity enlisted Wenner, who is also a beekeeper, to help in a survey in the Klamath River Basin. Each colony, with 50,000 bees, harvests pollen over an area of more than two square miles, collecting as many as 4 billion tiny samples in a year. The resulting data creates a clear, accurate picture of the plant life and pollution present in the environment.

‘Electronic tongue’ holds promise as possible first step to artificial emotional intelligence

Posted by in categories: food, robotics/AI

Can artificial intelligence (AI) get hungry? Develop a taste for certain foods? Not yet, but a team of Penn State researchers is developing a novel electronic tongue that mimics how taste influences what we eat based on both needs and wants, providing a possible blueprint for AI that processes information more like a human being.

Human behavior is complex, a nebulous compromise and interaction between our physiological needs and psychological urges. While has made great strides in recent years, AI systems do not incorporate the psychological side of our human intelligence. For example, emotional intelligence is rarely considered as part of AI.

“The main focus of our work was how could we bring the emotional part of intelligence to AI,” said Saptarshi Das, associate professor of engineering science and mechanics at Penn State and corresponding author of the study published recently in Nature Communications.

Beetle grows ‘termite’ on back to steal food

Posted by in categories: evolution, food

In what may be one of Earth’s craziest forms of mimicry, researchers have discovered a new species of rove beetle that grows a termite puppet on its back to fool real termites into feeding it. The replica is so precise, it even mirrors the termites’ distinct body segments and has three pairs of pseudoappendages that resemble antennae and legs.

Rove beetles (family Staphylinidae) are already infamous in the animal kingdom as masters of disguise. Some, for example, have evolved to look like army ants, allowing the beetles to march alongside them and feed on their eggs and young.

The new beetle species (Austrospirachtha carrijoi)—found beneath the soil in Australia’s Northern Territory—emulates a termite by enlarging its abdomen, a phenomenon known as physogastry. Evolution has reshaped this body part into a highly realistic replica of a termite (as seen above), head and all, which rides on top of the rest of the beetle’s body. The beetle’s real, much smaller head peeks out from beneath its termite disguise, the authors report this month in the journal.

Australian Seaweed Boosts Collagen Levels in Human-Like Skin Cells in The Lab

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

If you believe the headlines, seaweeds can do almost anything from storing tons of carbon and stopping cows from belching methane, to making biofuels and renewable plastics – all while sustaining vibrant coastal ecosystems and feeding communities.

Add to that list their potential wound-healing properties and possible anti-aging effects, and it’s no wonder the seaweed farming industry is booming.

A new study adds to that fanfare, with lab experiments based on human-like skin cells revealing extracts from two brown seaweeds can inhibit reactions linked to skin aging and boost collagen levels.

A new wearable sensor can monitor sweat in real time

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

The patch can calibrate the glucose measurements based on the pH and temperature changes in sweat due to factors such as exercise and eating.

A team of researchers at Penn State has developed a new wearable patch that can monitor your health by analyzing your sweat. The patch, which is made of a special material that can detect glucose, pH, and temperature in sweat, can provide valuable information about your body’s condition and help diagnose and manage diseases such as diabetes.

Migraine headaches: What are they and how do you treat them?

Posted by in categories: education, food

The first time it happened, I was in a high school physics class. Suddenly, I couldn’t read half of the board. A crack zig-zagged through my vision, obscuring my teacher’s notes. “Huh,” I thought. “This can’t be good.”

My classmate walked me to the school nurse, who called my mom. Pain rippled from the back of my neck to my forehead. I’d had headaches before, but not like this. “Ah, your first migraine,” Mom said. “Welcome to the club.”

For nearly a billion people worldwide, migraine attacks disrupt work, vacation and school. They can be triggered by stress, weather changes, hormone shifts, missed meals or sleep changes — in other words, just about anything. These reoccurring headaches often spur pain on one side of the head. They can last a few hours or a few days, and they can cause nausea along with sensitivity to noises and light.

Newly engineered CRISPR enzyme for editing DNA could improve patient treatment

Posted by in categories: bioengineering, biotech/medical, food, genetics

A new CRISPR-based gene-editing tool has been developed which could lead to better treatments for patients with genetic disorders. The tool is an enzyme, AsCas12f, which has been modified to offer the same effectiveness but at one-third the size of the Cas9 enzyme commonly used for gene editing. The compact size means that more of it can be packed into carrier viruses and delivered into living cells, making it more efficient.

Researchers created a library of possible AsCas12f mutations and then combined selected ones to engineer an AsCas12f with 10 times more editing ability than the original unmutated type. This engineered AsCas12f has already been successfully tested in mice and has the potential to be used for new, more effective treatments for patients in the future.

By now you have probably heard of CRISPR, the gene-editing tool which enables researchers to replace and alter segments of DNA. Like genetic tailors, scientists have been experimenting with “snipping away” the genes that make mosquitoes malaria carriers, altering food crops to be more nutritious and delicious, and in recent years begun to overcome some of the most challenging diseases and genetic disorders.
