Restaurants Are in Need of a Helping Hand. Miso Robotics Is Offering Them One. Literally

Posted by in categories: biotech/medical, employment, food, robotics/AI

Both are AI-enabled, allowing them to take in their surroundings and learn and evolve over time. They know what time to start cooking a well-done burger so that it’s done at exactly the same time as a medium-rare burger for the same order, or could learn how to optimize oil use to minimize waste, for instance.

In a pre-pandemic time of restaurant labor shortages, Flippy kept kitchen productivity high and costs low, a giant deal in an industry known for tiny margins. Introducing Flippy into a kitchen can increase profit margins by a whopping 300%, not to mention significantly reduce the stress managers feel when trying to fill shifts.

Here’s what potential Mars colonists really need from Earth: A large gene pool

Posted by in categories: biotech/medical, Elon Musk, existential risks, food, genetics

Sending a handful of people certainly could serve as a proof of concept analogous to America’s Spanish and Portuguese outposts in the early 1500’s, or the English and Dutch settlements in the early 1600’s. In these instances the populations measured in the dozens and would not have amounted to a lasting European presence had they not been followed by thousands of new settlers over the next few decades. But, given our more advanced technology, our level of medicine, the idea that humans could have equipment that will utilize the Martian environment to produce food, air, and other consumables, and the certainty that settlers will not be at war with the Martian equivalent of the Aztecs or Incas—couldn’t a Martian settlement survive long term with just a low number of colonists?

The answer is no—not if the goal is a permanent human presence. Not if the goal is to provide our species with some kind of extinction insurance against planetary disaster on Earth, such as a mega-volcanic eruption, nuclear war, or some other existential threat. Mars setters can use technology to get air and food from the Mars environment, but early European explorers in the New World had access to one natural resource that mid-21st century Mars colonists will not be able to manufacture: a human gene pool.

If we really want Martian colonies, we can’t send just a few Adams and Eves. We can’t set-up a Martian Jamestown of 100 people. Long-term survival will depend on the genetic diversity of a large gene pool, and this means the Elon Musk plan of sending thousands might be the only colonization plan that could work.

Cheese contains a chemical found in addictive drugs, scientists have found.

The team behind the study set out to pin-point why certain foods are more addictive than others.

The limits of color awareness during active, real-world vision

Posted by in categories: food, virtual reality

Color is a foundational aspect of visual experience that aids in segmenting objects, identifying food sources, and signaling emotions. Intuitively, it feels that we are immersed in a colorful world that extends to the farthest limits of our periphery. How accurate is our intuition? Here, we used gaze-contingent rendering in immersive VR to reveal the limits of color awareness during naturalistic viewing. Observers explored 360° real-world environments, which we altered so that only the regions where observers looked were in color, while their periphery was black-and-white. Overall, we found that observers routinely failed to notice when color vanished from the majority of their visual world. These results show that our intuitive sense of a rich, colorful world is largely incorrect.

Color ignites visual experience, imbuing the world with meaning, emotion, and richness. As soon as an observer opens their eyes, they have the immediate impression of a rich, colorful experience that encompasses their entire visual world. Here, we show that this impression is surprisingly inaccurate. We used head-mounted virtual reality (VR) to place observers in immersive, dynamic real-world environments, which they naturally explored via saccades and head turns. Meanwhile, we monitored their gaze with in-headset eye tracking and then systematically altered the visual environments such that only the parts of the scene they were looking at were presented in color and the rest of the scene (i.e., the visual periphery) was entirely desaturated. We found that observers were often completely unaware of these drastic alterations to their visual world. In the most extreme case, almost a third of observers failed to notice when less than 5% of the visual display was presented in color.

Aerosol-printed graphene unveiled as low cost, faster food toxin sensor

Posted by in categories: chemistry, food

Researchers in the USA have developed a graphene-based electrochemical sensor capable of detecting histamines (allergens) and toxins in food much faster than standard laboratory tests.

The team used aerosol-jet printing to create the sensor. The ability to change the pattern geometry on demand through software control allowed and efficient optimization of the sensor layout.

Commenting on the findings, which are published today in the IOP Publishing journal 2-D Materials, senior author Professor Mark Hersam, from Northwestern University, said: “We developed an aerosol-jet printable graphene ink to enable efficient exploration of different device designs, which was critical to optimizing the sensor response.”

Essential components of dietary restriction revealed

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

Another link on diet/healthspan.

Studies by Monash Biomedicine Discovery Institute (BDI), have provided a new understanding into the roles two essential amino acids play in metabolic health, which may help scientists in the fight against obesity.

Led by Dr. Adam Rose, the recent finding, published in Nature Communications, shows that by reducing the amount of two —threonine and tryptophan—in young healthy mice, they were able to burn more calories than they consumed, without calorie reduction, keeping them lean and healthy and without the side-effect of lower muscle mass. A low-threonine even protected mice that were morbidly obese and prone to developing type 2 diabetes.

Appetite can be increased by cells in the brain

Posted by in categories: food, neuroscience

It has previously been discovered that tanycytes—cells found in part of the brain that controls —detect nutrients in and tell the brain directly about the food we have eaten.

Tanycytes do this by responding to found in foods, via the same receptors that sense the flavor of amino acids (“umami” taste), which are found in the taste buds of the tongue.

In the paper ‘Hypothalamic tanycytes generate acute hyperphagia through activation of the arcuate neuronal network.’ published today, the 8th June, in the journal PNAS, researchers from the School of Life Sciences at the University of Warwick, explain how tanycytes can increase appetite.

Drug researcher develops ‘fat burning’ molecule that has implications for treatment of obesity

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

Mentions aging!

Obesity affects more than 40 percent of adults in the United States and 13 percent of the global population. With obesity comes a variety of other interconnected diseases including cardiovascular disease, diabetes, and fatty liver disease, which makes the disease one of the most difficult—and most crucial—to treat.

“Obesity is the biggest health problem in the United States. But, it is hard for people to lose weight and keep it off; being on a diet can be so difficult. So, a pharmacological approach, or a drug, could help out and would be beneficial for all of society,” said Webster Santos, professor of chemistry and the Cliff and Agnes Lilly Faculty Fellow of Drug Discovery in the College of Science at Virginia Tech.
