Knowing whether food has spoiled without even opening the container!
Research paper presented at a meeting of the American Chemical Society shows how.
A color-coded smart tag could tell consumers whether a carton of milk has turned sour or a can of green beans has spoiled without opening the containers, according to researchers. The tag, which would appear on the packaging, also could be used to determine if medications and other perishable products were still active or fresh, they said.

This report on the color-changing food deterioration tags was presented recently as part of the 247th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society.

When would people lie? Interesting Question. Phsycologists are trying to learn about it.

Psychologists Shaul Shalvi, Ori Eldar and Yoella Bereby-Meyer tested the hypothesis that people are more likely to lie when they can justify the deception to themselves in a 2013 paper entitled “Honesty Requires Time (and Lack of Justifications),” published in Psychological Science. Subjects rolled a die three times in a setup that blocked the experimenter's view of the outcome and were instructed to report the number that came up in the first roll. (The higher the number, the more money they were paid.) Seeing the outcomes of the second and third rolls gave the participants an opportunity to justify reporting the highest number of the three; because that number had actually come up, it was a justified lie.

Some subjects had to report their answer within 20 seconds, whereas others had an unlimited amount of time. Although both groups lied, those who were given less time were more likely to do so. In a second experiment subjects rolled the die once and reported the outcome. Those who were pressed for time lied; those who had time to think told the truth. The two experiments suggest that people are more likely to lie when time is short, but when time is not a factor they lie only when they have justification to do so.

“By lying, we deny our friends access to reality—and their resulting ignorance often harms them in ways we did not anticipate. Our friends may act on our falsehoods, or fail to solve problems that could have been solved only on the basis of good information.”

A practical solution is to think of a way to tell the truth with tact.

nearly all of us shade the truth just enough to make ourselves or others feel better. By how much do we lie? About 10 percent, says behavioral economist Dan Ariely in his 2012 book The Honest Truth about Dishonesty (Harper).

Lying, Ariely says, is not the result of a cost-benefit analysis. Instead it is a form of self-deception in which small lies allow us to dial up our self-image and still retain the perception of being an honest person. Big lies do not.

The Inflation Debate Is the theory at the heart of modern cosmology deeply flawed?

Why I Still Doubt Inflation, in Spite of Gravitational Wave Findings

here is what I’d like to see: First, corroboration of the BICEP2 findings by other groups and observatories. Second, experiments from high-energy physics that provide some sort of corroborating evidence of the driving mechanism of inflation. Third, an explanation of why the Alice’s Restaurant Problem isn’t still a problem. Fourth, an explanation of why only inflation, and not other more conventional physical phenomena, can account for the gravity-wave findings.

When these conditions are met, I’ll be happy to admit I was wrong about inflation. But multiverses? Never!

Honey is being used since ages in India to treat burns and various wounds that might harbour microbes that cause infection. Now researchers have found that
HONEY could be the key in the battle against antibiotic resistance. As well as being a tasty treat, honey could be used to help fight infections, they said.
Scientists at Salve Regina University in the US said that honey has a combination of weapons to beat infection including hydrogen peroxide, acidity, high sugar concentration and polyphenols – all of which actively kill bacterial cells.

Bionic Plants Offer Superpowered Photosynthesis
Rebuilding plants into bionic superpowered energy photosynthesizers ( using nanotechnology)

A team of MIT researchers writing in the journal Nature Materials say they have discovered the first steps in a new field of science known as “plant nanobionics.”

The researchers found that they were able to boost a plant's ability to capture light energy by 30 percent by embedding carbon nanotubes in the chloroplast. They were also able to use another type of carbon nanotube to modify the plants to detect nitric oxide.
