3D food printers head for mass production

By the end of the year, 3D food printers will be in people’s homes for the first time, with the first thought to be produced by Natural Machines.

While a few companies have been working on the technology, Natural Machine’s Foodini looks to be the first in an oncoming wave of mass production in 3D food printing.

The Foodini machine is an open capsule model, in which the user places fresh ingredients and then tells the Foodini what to make with them. For example, rather than hand making ravioli from start to finish, you just load the dough and filling into the machine and it will print individual ravioli for you.

The notion behind the machine, and where it fits into average household usage, is to encourage better eating.

According to the Natural Machines website: “Today, too many people eat too much convenience foods, processed foods, packaged foods, or pre-made meals – many with ingredients that are unidentifiable to the common consumer, versus homemade, healthy foods and snacks. But there is the problem of people not having enough time to make homemade foods from scratch.

“Enter Foodini. Foodini is a kitchen appliance that takes on the difficult parts of making food that is hard or time-consuming to make fully by hand. By 3D printing food, you automate some of the assembly or finishing steps of home cooking, thus making it easier to create freshly made meals and snacks.”  

The notion of replacing the hand crafting process of cooking with 3D printing may well seem a strange one, perhaps raising concerns of a reduction of people’s skill and effort. While it is certainly a better option than potentially more suspect ready meals, there is an element to which the idea of machines like the Foodini may detract from the craft of cooking.

However, although it allows those who would not usually be in a position to hand make ravioli to enjoy food they would otherwise not, it may also make it too easy for those who are able to make said food to simply not bother.

The worries of excess convenience aside, it is reassuring to see a focus on homemade food and quality eating. And with 3D printing ever developing, a future where we use it to manufacture our meals as well as our homes is perhaps not so far-fetched. As to when you should expect this, it is hard to say.

The Foodini currently sells at $4,000, somewhat above what the average consumer can be expected to spend. Yet if successful, a growing market could see the price steadily come down to the point where, in the future, we may expect every home to utilise 3D printing as a regular part of their cooking.

Natural Machines’ device will be initially released by the end of the year, but the next production batch will not be available until some time in 2017. So if you wish to be a part of the first wave of home 3D food printing, place your order quickly.

School will use facial analysis to identify students who are dozing off

In September the ESG business school in Paris will begin using artificial intelligence and facial analysis to determine whether students are paying attention in class. The school says the technology will be used to improve performance of students and professors.

The brain starts to eat itself after chronic sleep deprivation

Brain cells that destroy and digest worn-out cells and debris go into overdrive in mice that are chronically sleep-deprived. The discovery could explain why a chronic lack of sleep puts people at risk of neurological disorders like Alzheimer’s disease.

Juno mission: Jupiter’s magnetic field is even weirder than expected

It has long been known that Jupiter has the most intense magnetic field in the solar system, but the first round of results from NASA’s Juno mission has revealed that it is far stronger and more misshapen than scientists predicted.

Announcing the findings of the spacecraft’s first data-collection pass, which saw Juno fly within 2,600 miles (4,200km) of Jupiter on 27th August 2016, NASA mission scientists revealed that the planet far surpassed the expectations of models.

Measuring Jupiter’s magnetosphere using Juno’s magnetometer investigation (MAG) tool, they found that the planet’s magnetic field is even stronger than models predicted, at 7.766 Gaus: 10 times stronger than the strongest fields on Earth.

Furthermore, it is far more irregular in shape, prompting a re-think about how it could be generated.

“Juno is giving us a view of the magnetic field close to Jupiter that we’ve never had before,” said Jack Connerney, Juno deputy principal investigator and magnetic field investigation lead at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

“Already we see that the magnetic field looks lumpy: it is stronger in some places and weaker in others.

At present, scientists cannot say for certain why or how Jupiter’s magnetic field is so peculiar, but they do already have a theory: that the field is not generated from the planet’s core, but in a layer closer to its surface.

“This uneven distribution suggests that the field might be generated by dynamo action closer to the surface, above the layer of metallic hydrogen,” said Connerney.

However, with many more flybys planned, the scientists will considerable opportunities to learn more about this phenomenon, and more accurately pinpoint the bizarre magnetic field’s cause.

“Every flyby we execute gets us closer to determining where and how Jupiter’s dynamo works,” added Connerney.

With each flyby, which occurs every 53 days, the scientists are treated to a 6MB haul of newly collected information, which takes around 1.5 days to transfer back to Earth.

“Every 53 days, we go screaming by Jupiter, get doused by a fire hose of Jovian science, and there is always something new,” said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio.

An unexpected magnetic field was not the only surprise from the first data haul. The mission also provided a first-look at Jupiter’s poles, which are unexpectedly covered in swirling, densely clustered storms the size of Earth.

“We’re puzzled as to how they could be formed, how stable the configuration is, and why Jupiter’s north pole doesn’t look like the south pole,” said Bolton. “We’re questioning whether this is a dynamic system, and are we seeing just one stage, and over the next year, we’re going to watch it disappear, or is this a stable configuration and these storms are circulating around one another?”

Juno’s Microwave Radiometer (MWR) also threw up some surprises, with some of the planet’s belts appearing to penetrate down to its surface, while others seem to evolve into other structures. It’s a curious phenomenon, and one which the scientists hope to better explore on future flybys.

“On our next flyby on July 11, we will fly directly over one of the most iconic features in the entire solar system – one that every school kid knows – Jupiter’s Great Red Spot,” said Bolton.

“If anybody is going to get to the bottom of what is going on below those mammoth swirling crimson cloud tops, it’s Juno and her cloud-piercing science instruments.”
