Electronic components applied to implement IoT based smart farming systems, ranging from processors, sensors, signal conditioning, power management, connectivity, and positioning.

The IoT systems in smart farming have been depicted in six main sections by EET India, which are processors, sensors, signal conditioning, power management, connectivity, and positioning. Common use cases like automatic fertilization, automatic irrigation, crop management, precision farming, and livestock monitoring all can be realized through IoT systems. After sensors detect the environmental phenomena and target objects, the information will be transmitted to controlled processors through wireless connectivity. Then, the processors can collect and analyze these data, or even help farmers with further decision making.

A simple, cheap technology could help to boost food production and possibly allow crops to be grown in different places in order to cut down on food miles.

Hypoglycemic, anti-inflammatory, and antioxidant activities of fennel have been recorded in numerous investigations. The study aimed to evaluate the protective effects of fennel or its active component trans-Anethole (TA) on streptozotocin-induced liver injury in rats. Rats were injected with a single dose of STZ (65 mg/kg) and treated with fennel (200 and 400 mg/kg), TA (80 mg/kg), or metformin (300 mg/kg) for 35 days. Serum lipid profile and liver enzyme activity (aminotransferases), oxidative stress markers, and the degree of fibrosis in the liver tissue were assessed. Both fennel and TA decreased blood glucose levels, reduced liver enzyme activity, food, and water intake, and intensity of weight loss, reduced serum triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), and increased high-density lipoprotein cholesterol (HDL-c). Additionally, fennel and TA significantly reduced MDA concentration while increased CAT activity and thiol content and reduced the degree of injury and fibrosis in the liver of diabetic rats. Our results suggest that fennel seed extract and its active compound TA are able to protect the liver against diabetes-induced hepatic injury in rats, probably via hypoglycemic and antioxidant effects.

The effects of fennel seed extract and its active compound trans-Anethole were investigated in the STZ-induced liver injury in rats. Both fennel and trans-Anethole effectively reduced blood glucose l…

Some interesting new information on how humans use energy and why exercise is not necessarily useful for losing weight (though it can help prevent gaining weight in the first place and of course is good for health).

I’m still curious why I accidentally lost about 30 pounds without intending to while I was eating probably twice as much as normal when I spent three months at the South Pole (2007−08). Did the cold increase my brown fat and my metabolism? Did it have something to do with unpolluted air and water? Was it a difference in the food, most of which was from New Zealand? Was it the high altitude (equivalent to about 10,500 feet at the equator)? Did the roughly 30 pounds of extra clothing I wore every day somehow trigger weight loss to “maintain” my previous weight? Something else?

As this example shows, there is still a great deal we can learn about these questions which are crucial to maintaining human health.

The robot takeover starts at the drive thru as fast food rapidly turns to automation.

Before the pandemic started (ah, those glorious days…) a collective panic was mounting over automation and robots gradually replacing workers in various fields, or “stealing our jobs,” as the common refrain went. These worries haven’t subsided two years later, but they’re being countered by severe and largely unexpected labor shortages across multiple sectors of the economy. One of the industries that’s struggling most is restaurants. While we may still encounter automation-related unemployment problems down the road, right now it seems robots are lending a much-needed hand in food service.

One of these robots is none other than Flippy, initially debuted in 2017 to flip burgers at a California fast food chain. Since then Miso Robotics, Flippy’s maker, has expanded the bot’s capabilities, creating a version that can cook chicken wings, fries, and other greasy delights. This week also brought a significant expansion to Flippy’s presence as White Castle announced plans to install the robot at more than 100 restaurants this year.

Scientists have uncovered a set of neurons in fruit flies that shut down in cold temperatures and slow reproduction, a system conserved in many insects, including mosquitoes, which could provide a target for pest control.

Their study, published Feb. 16 in the journal Current Biology, takes a step toward understanding how a fly’s brain contributes to sensing the cold and limiting reproduction. Insects and animals, including many mammals, curb reproduction in the winter to protect their newborns from being exposed to harsh winter conditions.

The study has public health and agricultural implications, as tapping into environmentally-dependent mechanisms that influence reproduction in mosquitoes and crop pests may offer new control strategies. Mosquitoes act as reservoirs for the malaria-causing Plasmodium falciparum parasite, which spend the winter inside them.
