Episodic memory is also known as long-term memory, and the researchers approached the study of exercise in a different manner than previous studies. Other studies examined the impact of aerobic exercise conducted over many months, but this study simply asked participants to lift weights a single time. During the test, half of the participants were asked to use a weight machine before recalling a series of images they were shown at the start of the test. The other half of the participants were also asked to recall the images but without having engaged in any strenuous activity before the recall session. In demonstrating the memory improvement for the participants who engaged in just a single session of weight lifting, the researchers were able to show that improving one's memory through exercise didn't take hours of dedication in the gym. The next time you have the opportunity to lift weights or someone tries to convince you to join the gym you might just want to take him or her up on the offer.
Will China's stock market climb back to the 6,000-point mark it reached two years ago? The stock market was at its most bullish back then, but if you ask the same question now, some would cite a global economy still reeling from a recession.
'There are two ways of doing natural language processing: statistical or semantic,' D'Aloisio explains. A semantic system attempts to figure out the actual meaning of a text and translate it succinctly. A statistical system-the type D'Aloisio used for Summly-doesn't bother with that; it keeps phrases and sentences intact and figures out how to pick a few that best encapsulate the entire work. 'It ranks and classifies each sentence, or phrase, as a candidate for inclusion in the summary. It's very mathematical. It looks at frequencies and distributions, but not at what the words mean.'

‘Jeopardy!’ This game show celebrated the 50th anniversary of its debut (broadcast on March 30, 1964), and proved it can still not only stump viewers but also surprise them. That’s not just because the host, Alex Trebek, briefly regrew a mustache after 13 clean-shaven years, but also because some contestants showed they could still rile an audience. This year, it was Arthur Chu, who introduced a blitzkrieg style of gamesmanship that provoked a cyber hate-fest. His strategy was thrilling and certainly effective: he came in second in the Tournament of Champions. (Ben Ingram, the nice guy, finished first.)
