Seventy years ago, more than 160,000 Allied troops stormed the beaches of Normandy during the D-Day invasion. And while we all know that day served as a huge turning point for the Allied cause you probably haven't thought much about what those ,soldiers carried with them to eat during and after the invasion. Food had to be lightweight, nutritious and very high in energy; after all, these men were about to invade Nazi-occupied land. As it happened, the one substance that could fulfill all those requirements was a very unlikely item--a Hershey's chocolate bar.
The Hershey chocolate company was approached back in 1937 about creating a specially designed bar just for U.S. Army emergency rations. According to Hershey's chief chemist SamHinkle, the U.S. government had just four requests about their new chocolate bars: they had tow eight 4 ounces, be high in energy, withstand high temperatures and "taste a little better than a
boiled potato". The final product was called the "D ration bar", a blend of chocolate, sugar, cocoa butter, skim milk powder and oat flour. The viscous mixture proved too thick to move through the normal chocolate bar manufacturing set up at the Hershey plant, so initially each bar had to be packed into its 4-ounce mold by hand.
As for taste, well, most who tried it said they would rather had eaten the boiled potato. The combination of fat and oat flour made the chocolate bar a dense brick, and the sugar did little to mask the overwhelmingly bitter taste to the dark chocolate. Since it was designed to withstand high temperatures, the bar was nearly impossible to bite into. Most men who ate it had to shave slices off with a knife before they could chew it. And despite the U.S. Army's best efforts to stop the men from doing so, some of the D ration bars ended up in the trash. Later in the war, Hershey introduced a new version, known as the Tropical bar, specially designed for extreme temperatures of the Pacific Theater. By the end of the war, the company had produced more than 3 billion ration bars.
But "Hitler's Secret Weapon", as many infantrymen referred to the chocolate bar, was hardly the only candy in the D-Day rations. Candy was an easy way to pep up the troops, and the quick burst of energy provided by sugar was a welcome addition to kit bags. Along with the D rations, troops received three days worth of K ration packs. These were devised more as meal replacements and not sustenance snacks like the D rations, and came completely with coffee, canned meats, processed cheese and tons of sugar. At various points during the war, men could find powdered orange or lemon drink, caramels, chewing gum and--of course--more chocolate. Along with packs of cigarettes and sugar cubes for coffee, the K ration packs provided plenty of valuable energy for fighting men.

More and more gadgets seek to replicate the sorts of things your mother used to needle youabout: getting exercise, eating more slowly or brushing your teeth. Now one company has decided toembrace that image--it has named iom a firm called Sense, caught my eye at a press preview for the 2014 ConsumerElectronics Show in Las Vegas, in part because of its unique design. It looks like a cross betweenWALL-E's girlfriend EVE and Russian nesting dolls. Mother has slightly creepy glowing eyes--butsurely has your best interest at heart? Mother's potential use is intriguing: Each Mother unit talkswirelessly to a set of smaller tracking devices, dubbed cookies, which can sense motion andtemperature. You can put cookies on things and people--on your body to gather data about how muchyou walk, on your coffee machine to track many espressos you drink, on your front door to trackwhenever it is opened, on your toothbrush to see how often and how long you brush ... and so forth.
Whenever the cookies get close to the Mother unit, they wirelessly send back their data to theInternet.
The company says users of Mother, which is supposed to start shipping in the spring, will beable look at all their information at once, or drill down on certain topics. And if something is reallyimportant, you can have an alert sent to your phone when a sensor detects a change.
So what does all that data do for you? That's a question that bedevils many Internet of Thingsgadgets on display here at CES. Mother's makers say the data she tracks can help you gain peaceof mind by answering specific questions in your life, such as,"Am I drinking enough water?" or,"Did somebody open my secret drawer?"
Lots of companies want to connect parts of your body, home and life to the Internet--a trendcalled the "Internet of Things". Mother's maker, Rafi Haladjian, told me he thinks having separatedevices for all these things is too expensive and too cumbersome because they can't talk to eachother."There are not so many needs that are worth $200" for a distinct Internet-connected device,he said.
Mother, which costs $222 for a base unit and four cookies, is designed to be repurposed asnew challenges or needs spring to mind, he said. It's kind of like a mobile device that can run anever-changing array of apps.
Where did the name come from? "We need a device that does all sort of things," Haladjiansaid. "The metaphor that matched this noble caring figure is the mother. She is not a nurse, agardener or a cop--she is everything at the same time."

Several decades ago, the US sociologists went so far as to develop a series of universal facial images supposed to represent the seven basic human emotions: happiness, sadness, surprise, fear, disgust, anger and neutrality. But now, a new study by researchers at the University of Glasgow indicates that these standardized facial images aren't so universal after all.
For the study, the Scottish researchers found 13 Western Caucasians (mainly Europeans) and 13East Asians (mostly Chinese students). The volunteers were shown the standardized facial images and asked to identify the emotions being expressed. At the same time, the researchers electronically monitored the eye movements of the volunteers.
According to the results, published in the journal Current Biology, the Asian participants had a harder time than the Caucasians telling the difference between a face meant to look fearful compared with one showing surprise, and a face supposedly expressing disgust compared with one displaying anger. "This strongly suggests that the meanings of facial expressions are different across culture." says Rachael Jack, who led the study.
The study also showed that the volunteers focused on different parts of the face in their efforts to understand the underlying emotions. "Westerners look at both the eyes and the mouth to the same degree, yet Easterners favor the eyes and overlook the mouth. This means that Easterner shave difficulties distinguishing facial expressions that are similar around the eyes." Ms Jack says. The faces representing fear and surprise "both have big, wide open eyes, while the mouths are very different." She notes. "It would be difficult to distinguish between the two ... if you didn't look at the mouth."
So why would different cultures express emotions in different ways? Ms Jack thinks it may be considered impolite in some Asian cultures to display certain emotions in an obvious manner, and that they use more subtle ways to express them. In particular, muscle movements around their eyes could be more important for expressing feelings than over-expressive mouth movements, explaining why the Asian participants focused on the eyes, she says.
