How microgrids could boost resilience in New Orleans

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

During Hurricane Katrina and other severe storms that have hit New Orleans, power outages, flooding and wind damage combined to cut off people from clean drinking water, food, medical care, shelter, prescriptions and other vital services.

In a year-long project, researchers at Sandia and Los Alamos national laboratories teamed up with the City of New Orleans to analyze ways to increase community resilience and improve the availability of critical lifeline services during and after severe weather.

The team used historical hurricane scenarios to model how storms cause localized flooding, disrupt the electrical system and cut off parts of the community from lifeline services. Sandia researchers then developed a tool to analyze and identify existing clusters of businesses and community resources in areas less prone to inundation—such as gas stations, grocery stores and pharmacies that could be outfitted with microgrids to boost resilience.

Researchers reveal how disrupting gut-brain communication may affect learning and memory

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

The connection between food and memory is one of those fundamentally human experiences we can all relate to. A compelling new study from the University of Southern California has revealed an intriguing explanation behind this phenomenon, and it illustrates how strongly the “second brain” in our gut communicates with our brain.

Inside our gastrointestinal tract lies a massive mesh of neurons often referred to as our “second brain.” While this neuronal control system primarily works to independently manage our digestive system, it also has been found to directly communicate with the brain via a long nerve, called the vagus nerve.

The vagus nerve has been found to mediate a great deal of metabolic communication between the gut and the brain. For example, one recent study revealed how feeding behavior, modulated by activity in the hippocampus, is directly activated by vagal nerve stimulation, mediated by signals from the gastrointestinal tract.

Lentils significantly reduce blood glucose levels, study reveals

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

Replacing potatoes or rice with pulses can lower your blood glucose levels by more than 20 per cent, according to a first-ever University of Guelph study.

Prof. Alison Duncan, Department of Human Health and Nutritional Sciences, and Dan Ramdath of Agriculture and Agri-Food Canada, found that swapping out half of a portion of these starchy side dishes for can significantly improve your body’s response to the carbohydrates.

Replacing half a serving of rice with lentils caused to drop by up to 20 per cent. Replacing potatoes with lentils led to a 35-per-cent drop.

Starch can replace normal plastic in food packaging

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

Eventually all petroleum-based material in food packaging will have to be replaced with bio-based material. Research done at Karlstad University shows that a mixture of starch and other polymers forms an equally effective protective barrier.

“Food packaging has to protect and extend the of food, and should also work during transport,” says Asif Javed, doctor in Chemical Engineering at Karlstad University. “To meet these demands, a protective barrier is needed in paper-based packing such as those used for juice or dairy.”

Isaac Launches New Era of Autonomous Machines

Posted by in categories: food, robotics/AI

ComputexNVIDIA today announced the availability of NVIDIA® Isaac™, a new platform to power the next generation of autonomous machines, bringing artificial intelligence capabilities to robots for manufacturing, logistics, agriculture, construction and many other industries.

Launched at Computex 2018 by NVIDIA founder and CEO Jensen Huang, NVIDIA Isaac includes new hardware, software and a virtual-world robot simulator.

“AI is the most powerful technology force of our time,” said Huang. “Its first phase will enable new levels of software automation that boost productivity in many industries. Next, AI, in combination with sensors and actuators, will be the brain of a new generation of autonomous machines. Someday, there will be billions of intelligent machines in manufacturing, home delivery, warehouse logistics and much more.”

Cockroach sushi? Inside a farming revolution that could cure cancer, compost waste – and shake up menus

Posted by in categories: biotech/medical, food

There is a history of insects’ acceptability as ingredients for Chinese medicine, as pets, and even as food. Yet in selling the idea to the general public, especially those living in big cities, there is still a way to go.


Hundreds of cockroach farmers across China are unleashing the insects’ potential in the country’s war on waste, in medicine, and deep or stir-fried.

News: SMAP, the spacecraft I once worked on, is providing relative moisture data from the Earth’s surface

Posted by in categories: food, health, space travel

It’s interesting to note that eastern Texas, Louisiana and Arkansas are experiencing much less soil moisture during the middle of May…


Data from the first NASA satellite mission dedicated to measuring the water content of soils is now being used operationally by the U.S. Department of Agriculture (USDA) to monitor global croplands and make commodity forecasts.

The Soil Moisture Active Passive mission, or SMAP, launched in 2015 and has helped map the amount of water in soils worldwide. Now, with tools developed by a team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, SMAP soil moisture data are being incorporated into the Crop Explorer website of the USDA’s Foreign Agricultural Service, which reports on regional droughts, floods and crop forecasts. Crop Explorer is a clearinghouse for global agricultural growing conditions, such as soil moisture, temperature, precipitation, vegetation health and more.

Scientists develop material that could regenerate dental enamel

Posted by in categories: biotech/medical, food

Researchers at Queen Mary University of London have developed a new way to grow mineralised materials which could regenerate hard tissues such as dental enamel and bone.

Enamel, located on the outer part of our teeth, is the hardest in the body and enables our teeth to function for a large part of our lifetime despite biting forces, exposure to acidic foods and drinks and extreme temperatures. This remarkable performance results from its highly organised structure.

However, unlike other tissues of the body, cannot regenerate once it is lost, which can lead to pain and tooth loss. These problems affect more than 50 per cent of the world’s population and so finding ways to recreate enamel has long been a major need in dentistry.

A protein activated

Posted by in categories: biotech/medical, food

Weight gain has often been noted as a side effect of quitting smoking, and research has well established that nicotine can function as an appetite suppressant. A new study has now uncovered a novel mechanism showing how nicotine directly activates a protein that signals a type of fat cell to start burning energy.

A few years ago, scientists discovered a new, third type of fat cell called beige fat. This important discovery revealed an entirely new metabolic target for obesity research. Along with brown fat cells, beige fat was found to rapidly burn calories and generate heat.

Now, new research from the University of Michigan Life Sciences Institute has revealed a novel metabolic mechanism explaining how a protein called CHRNA2 specifically stimulates beige fat cells to burn energy. The study found that CHRNA2 receptor proteins are activated by two molecules – nicotine and acetylcholine.
