KFC’s latest weird tech suggests an order based on your face
If you loathe having to talk out loud when ordering a meal at a fast-food restaurant, and you happen to love KFC, then you might want to start considering packing it up and moving to China where Baidu has just teamed up with the major chicken brand to create a more automated restaurant. The venture aims to use the company’s latest technologies to bring novel ways of providing service to KFC customers.
As an added feature, the outlet also offers augmented reality games via table stickers, a concept also made available to 300 other KFC locations in Beijing.
Baidu’s tech in this new restaurant, however, is all about guessing what you want before you can even ask; image recognition hardware installed at the KFC will scan customer faces, seeking to infer moods, and guess other information including gender an age in order to inform their recommendation.
Biology’s ‘breadboard’
Nice; using gene regulatory protein from yeast as a method for reducing the work required for making cell-specific perturbations.
The human brain, the most complex object in the universe, has 86 billion neurons with trillions of yet-unmapped connections. Understanding how it generates behavior is a problem that has beguiled humankind for millennia, and is critical for developing effective therapies for the psychiatric disorders that incur heavy costs on individuals and on society. The roundworm C elegans, measuring a mere 1 millimeter, is a powerful model system for understanding how nervous systems produce behaviors. Unlike the human brain, it has only 302 neurons, and has completely mapped neural wiring of 6,000 connections, making it the closest thing to a computer circuit board in biology. Despite its relative simplicity, the roundworm exhibits behaviors ranging from simple reflexes to the more complex, such as searching for food when hungry, learning to avoid food that previously made it ill, and social behavior.
Understanding how this dramatically simpler nervous system works will give insights into how our vastly more complex brains function and is the subject of a paper published on December 26, 2016, in Nature Methods.
Food withdrawal results in stabilization of important tumor suppressor
Caloric restriction can help tumour supression.
Tumor suppressors stop healthy cells from becoming cancerous. Researchers from Charité — Universitätsmedizin Berlin, the Medical University of Graz and the German Institute of Human Nutrition in Potsdam-Rehbruecke have found that p53, one of the most important tumor suppressors, accumulates in liver after food withdrawal. They also show that p53 in liver plays a crucial role in the body’s metabolic adaptation to starvation. These findings may provide the foundation for the development of new treatment options for patients with metabolic or oncologic disorders. Results of this study have been published in The FASEB Journal.
Previously described as the ‘guardian of the genome’ and voted ‘Molecule of the Year’ in 1993, p53 is one of the most important proteins regulating cell growth and a major focus for oncology research. It is a protein that has the ability to interrupt the cell cycle and block the division of diseased cells. In order to better understand its physiological regulation, the researchers around Prof. Dr. Michael Schupp from Charité’s Institute of Pharmacology studied the regulation and function of p53 in normal, healthy cells. After withholding food from mice for several hours, the researchers were able to show that p53 protein accumulates in the liver. In order to determine which type of liver cells cause this accumulation, the researchers repeated the experiment using cultured hepatocytes. They found that the starvation-induced accumulation of p53 was indeed detectable in hepatocytes, irrespective of whether these cells were of mouse or human origin.
“Our data also suggest that the accumulation of p53 is mediated by a cellular energy sensor, and that it is crucial for the metabolic changes associated with starvation,” explains Prof. Michael Schupp. The researchers were able to show that mice with an acute inactivation of the p53 gene in liver had difficulties in adapting their metabolisms to starvation. “Food intake seems crucial in determining the protein levels of p53 in liver, and p53 also plays an important role in normal liver metabolism,” says Prof. Schupp. The researchers are planning to study whether their observations are limited to liver cells, or whether this p53 accumulation also occurs in other tissues and organs.

Interstellar Human Hibernation –Science of Deep-Space Travel from From ‘Aliens’ to ’Arrival‘
In “Passengers,” a 2016 science-fiction thriller film two space travelers wake up 90 years too soon from an induced hibernation on board a spaceship bound for a new planet. From “Aliens” to “Interstellar,” Hollywood has long used suspended animation to overcome the difficulties of deep space travel, but the once-fanciful sci-fi staple is becoming scientific fact. The theory is that a hibernating crew could stay alive over vast cosmic distances, requiring little food, hydration or living space, potentially slashing the costs of interstellar missions and eradicating the boredom of space travel.
The perfect Christmas gift? A nanoscale snowman
Happy Holidays; happy end of the year, happy launch of next year, happy snow days, happy hot chocolate day, etc. Nonetheless, my gift to you this year is a Nanoscale Snowman.
Would a jewel-encrusted snowman make the perfect Christmas present? At only 5 nanometres in size, the price might be lower than you think. And it’s functional too, catalysing the splitting of water to make green hydrogen for fuel cells.
The nanoparticle, as imaged with the aberration-corrected scanning transmission electron microscopes, features eyes, nose and mouth of precious-metal platinum clusters embedded in a titanium dioxide face. Each platinum cluster typically contains 30 platinum atoms; within the whole nanoparticle there are approximately 1680 titanium atoms and 180 platinum atoms.
The nano-snowman formed spontaneously from a self-assembled platinum-titanium nanoparticle which was oxidised in air, drawing the titanium atoms out to the surface. The self-assembly occurred in a gas phase, cluster beam condensation source, before size-selection with a mass spectrometer and deposition onto a carbon surface for oxidation and then imaging. The mass of the snowman was 120,000 atomic mass units. Compared with a more conventional pure platinum catalyst particle, the inclusion of the titanium atoms offers two potential benefits: dilution of how much precious platinum is needed to perform the catalysis, and protection of the platinum cores against sintering (i.e. aggregation of the nanoparticles). The shell is porous enough to allow hydrogen through and the particles are functional in the hydrogen evolution reaction.
FDA approves pink, genetically engineered pineapple from Del Monte
(FoxNews.com) — Food producer Del Monte has received approval from the Food and Drug Administration to start selling a genetically engineered pineapple with pink flesh.
The new species Ananas comosus has been given the more consumer-friendly name of the “Rosé” and, according to The Packer, Del Monte has quietly been working on the fruit’s development since 2005.
So what makes the usually golden-colored fruit pink? The patened pineapple DNA is injected with a healthy dose of lycopene, the bright red pigment found in tomatoes and watermelons.
Monster-wheat grown by Oxford could revolutionise farming
A crop spray which can boost farmer’s wheat yields by one fifth, without the need for genetic modification, has been developed by scientists at Oxford University.
Researchers have found a molecule which helps plants make the best use of the sugary fuel that they generate during photosynthesis. And with more fuel, the plants can produce bigger grains.
Other scientists in Britain have developed ways to genetically modify crops to increase yields, and the Department of Environment is currently deciding whether to allow a field trial for GM wheat in Hertfordshire.
Turning the potential of electronic printables into a real breakthrough
Those “sell by” or “best by” dates that you see on food packaging? They’re so last century. In the future, built-in sensors in food labels will not only tell you when a product is going bad but also if you’re storing it correctly. Some might even be able to give you a breakdown of its nutritional data. All this is thanks to developments in the burgeoning world of printable electronics. Now researchers at MIT have invented a printing process that could turn a lot of the potential breakthroughs, such as electricity-generating clothing and smart sutures we’ve been seeing in this space, into an inexpensive reality.
“There is a huge need for printing of electronic devices that are extremely inexpensive but provide simple computations and interactive functions,” says A. John Hart, an associate professor in contemporary technology and mechanical engineering.
While some researchers have been studying the possibility of using inkjet printing and rubber stamping, these techniques have produced mixed results at best, often resulting in fuzzy, coffee-ring patterns or incomplete circuits due to the difficulty of controlling ink flow at such small scales.
