1 . We've long known that crows exhibit extraordinary intelligence. These birds have inspired legends for centuries. But the more scientists know about their brain structure and behaviors, the more crows seem to resemble humans.
John Marzluff, a professor from the University of Washington, has been studying crows for decades. He's explored the exceptional size and function of crow brains, their long life and lifestyle. “Big brain, long life and sociality, those are really linked features,” Marzluff says. “You put those together, and it should sound pretty familiar.”
To top that off, just last fall other researchers determined that crows seem to exhibit a level of consciousness shown only in humans and very few of our mammal relatives. The breakthrough study published in Science showed that crows have an ability to draw on subjective experiences from the past in order to solve a task. This means the birds keep new information, or memories, in the front of their brains for extended periods, and use it in reasoning and dealing with new situations they meet.
That is, for people and crows alike, the forebrain deals with higher tasks, including reasoned decision-making, problem-solving and executive function. Taken together, these findings help explain the problem-solving and tool use in crows. The New Caledonian crow, for example, has recently gained welcome for not only tool use, but its ability to make compound tools out of various materials. These birds have been known to make hooks and sharp spears that they use to catch insects in hard-to-reach places. In research labs, they've successfully bent wire to grab baskets with food inside.
“They understand the concept of hooking and-pulling and spearing and what tools are needed to do that,” Marzluff says. These reasoning skills appear to be significantly more advanced than primitive tool use—such as using rocks to break open shells and other food—that researchers have observed in some other animals.

2 . For better or worse, many of us never forget those typical British school days—and with a site that now has over 32, 200 educational institutions as well as a growing number of users, you won't have to.
SchoolMates is a nice networking platform which offers a refreshing alternative to traditional social media in that the focus is on building more meaningful relationships and encouraging interaction between users. While social media sites are customarily designed to form an interactive online community, SchoolMates aims to help people find friends from their past.
“At SchoolMates, our mission is simple. We've created a platform aimed specifically to help people reconnect and keep in touch with former classmates,” explains founder and CEO Chris Goodwin. “Our site encourages people to revive those special relationships from their youth, letting them look back to the ‘good old days’ of summer holidays spent with friends, memorable school trips, as well as less memorable moments like those awful school lunches.”
SchoolMates brings together more than 32, 000 schools, colleges, academies and universities across England, Scotland, Northern Ireland and Wales and is aimed to help users get back in touch with former classmates. Aimed at the 35 plus age group, which represents 50% of the population, the easy-to-use website enables users to recall and share conversations, jokes, stories, memories and photographs.
Chris was diagnosed with a tumour at the age of 18. He couldn't move and could only sit in a wheelchair. Determined to conquer the world of the Internet and own a successful online business since completing his studies in computer science, he did not let his disability become an excuse to give up on his dreams; he had a successful business career before going on to start up SchoolMates.

6 . TOKYO, Japan—Maki Kaji, 69, the creator of the popular numbers puzzle Sudoku whose life's work was spreading the joy of puzzles, has died of cancer.
Known as the “Godfather of Sudoku,” Kaji created the puzzle to be easy for children and others who didn't want to think too hard. Its name is made up of the Japanese characters for “number” and “single,” and players place the numbers 1 through 9 in rows, columns and blocks without repeating them.
Ridiculously, it wasn't until 2004 that Sudoku became a global hit, after a fan from New Zealand got it published in the British newspaper The Times. Two years later, Japan rediscovered its own puzzle as a “reimport.”
Kaji traveled to more than 30 countries spreading his enjoyment of puzzles. Sudoku championships have drawn some 200 million people in 100 countries over the years. Sudoku was also never trademarked (注册) except within Japan, driving its overseas craze.
Born in the main northern island of Hokkaido, Kaji started Japan's first puzzle magazine after dropping out of Keio University in Tokyo. He founded Nikoli in 1983, and came up with the name Sudoku about the same time. In recent years, Sudoku, believed to be the world's most popular pencil puzzle, has come out in digital versions.
“Our mission (使命) is to seek Kaji's wishes and possibilities,” said Yoshinao Anpuku, who succeeded Kaji as Nikoli's chief executive (执行官). Major Japanese newspaper Mainichi credited Kaji for starting the puzzle sections at bookstores, as well as introducing the word “Sudoku” into the Oxford English dictionary.
