The Mars Farm Odyssey group is thinking of non-NASA-approved solutions for making sure our colonists on the red planet have food (and weed).

Increasingly the vegetarian diet seems promising in terms of longevity strategy. Here is a short article exploring this idea.

Our ability to live a long life is influenced by a combination of our genes and our environment. In studies that involve identical twins, scientists have estimated that no more than 30 percent of this influence comes from our genes, meaning that the largest group of factors that control how long a person lives is their environment.

Of the many possible environmental factors, few have been as thoroughly studied or debated as our diet. Calorie restriction, for example, is one area that is being investigated.

Struggling with your diet? Your microbiota could be to blame.

Your microbiota may not be on your side as you try improving your diet this New Year’s. In a study published December 29 in Cell Host & Microbe, researchers explore why mice that switch from an unrestricted American diet to a healthy, calorie-restricted, plant-based diet don’t have an immediate response to their new program. They found that certain human gut bacteria need to be lost for a diet plan to be successful.

“If we are to prescribe a diet to improve someone’s health, it’s important that we understand what microbes help control those beneficial effects,” says Jeffrey Gordon, Director of the Center for Genome Sciences and Systems Biology at Washington University in St. Louis and senior author of the paper. “And we’ve found a way to mine the gut microbial communities of different humans to identify the organisms that help promote the effects of a particular diet in ways that might be beneficial.”

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.

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.

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.

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.
