Q: Article: A board game is a game played on a pre-marked surface or "board" according to a set of rules. Board games have been played in most cultures and societies throughout history. Do you think of yourself as a bit of an expert at board games like chess or Go? Maybe you're not quite as good as you think. New research from the University of Manchester and Oxford suggests complex games like these are impossible to learn fully. They may even be too complex for the human mind to understand. Researchers studied two-player games, to try and understand the strategies which people use to make decisions during the game. Some games with two players are simple, with only a small number of possible moves. Players can quickly work out the best strategy but that means the game soon becomes boring. It gets more interesting when there are many possible moves. That's why people are so fascinated by complex board games like chess or Go, or some card games. But what the researchers found was that with difficult games, players find it hard to work out the best strategy and their actions become less reasonable. This research is part of the field called game theory: the study of human strategic decision-making. Much thinking on how people play complex games is based on something called "the balance point", which is when players have a perfect knowledge of what they are going to do and of what their rivals are going to do. When you add more than two players then of course the game becomes even harder to understand. Trading on the stock market is an example of a complex multi-player game.

Q: Article: Research has shown that 85 percent of communication is nonverbal, so choosing what to wear to an interview is clearly an important part of your overall presentation. It won't make up for weak answers, but it can communicate some positive things about your personality and what you might be like to work with. * Blue: You can't go wrong with darker shades of blue, especially navy. Choosing from this powerful color1 will project an image of someone who is in control. From the interviewer's point of view, the color1 blue suggests calm, stability, trust, truth, confidence and security. These are all great messages to send without saying a word. * Gray: After blue, gray is the second most popular color to wear for an interview. Like darker blue, it's not a distracting color1 to the interviewer, which means they'll be focused more on what you're saying and how you're saying it. Gray means sophistication , so use it to your advantage. * Black: This is a commanding color1 and represents authority. Black also suggests excitement, so use it carefully when putting together your interview outfit. You may want to use it as an accent --like in a scarf or tie, for instance--rather than as the primary color. * Red: This is an extremely powerful color1. It's so strong that you should only use it as an accent color1. Reds are associated with energy, passion, desire, power and aggression. People think of intensity and passion when they see the color1 red, so use it carefully or it could send the wrong message to the interviewer. * White: White shirts and blouses are always appropriate. It sends the message of simplicity, cleanliness, precision and goodness.

Q: Article: Almost all of us have been there: A sense of uneasiness strikes us when we see the battery running low on the smartphone. While today's smartphones enable us to surf the Internet, take pictures and play music, their limited, sometimes annoyingly short battery life has started to make people full of memories of early models. "My favorite phone of all time was a silver Nokia 6310i from the early 2000s. It may be primitive by today's standards, but it could run for 17 days on a single charge," wrote Daily Mail columnist David Derbyshire. But scientists spend no time thinking about the past. They have built an aluminium battery which could be a cheap, fast-charging alternative to current designs. You can squeeze, and practically bend it in half without breaking the packet. It is more environmentally friendly than alkaline batteries, and more safe than lithium batteries - it won't catch fire "even if you drill through it", as Hongjie Dai of Stanford University told The Telegraph. The battery is the work of a team led by Dai. And the best part is that it has a recharge time of around one minute. However, at present, the only problem is that it produces just half the voltage of a typical lithium battery. But Dai explained they were setting about changing the voltage and energy density ". "Our battery has everything else you'd dream that a battery should have. I see this as a new battery in its early days," he told The Telegraph.
