What if you were the last person alive? Movie makers and authors continue to spend a lot of time and money on imagining a world when mankind has left the building, but we have the scientific version this issue. And it’s fascinating… To push the scenario along, but in a more fun way, we also have an engaging feature on Mars, and how the portrayal of the Red Planet over the years has mirrored the state of the world Away from gloom and doom, we’re loving our portfolio of cool photographs of flamingos; they make such a dramatic contrast to almost-colourless landscapes. Viruses come in for rare approbation too, with an analysis of how they play a part in keeping us alive. On our history menu is a captivating profile of BT Barnum, aptly…

WILDLIFE Special! Like you, dear Editor, I, too, have never seen a tiger in the wild, though I have undertaken tiger safaris in some of India’s best wildlife parks. I once went through this ritual every day for five consecutive days at Corbett, but without success except for the occasional roar of the tiger. I personally feel we are over-obsessed with tigers when there are many other wonderful animals and birds in the wild, like the gharial and the wild boar. That’s why I thoroughly enjoyed reading the wildlife issue of BBC Knowledge that gave me valuable information about other creatures of the wild, besides the tige Om Prakash Pareek, via email BBC Knowledge is my favourite magazine. The content is unique and new, and that makes this magazine special. I hunt through…

do we need holiday homework?

Panel of Principals is a knowledge circle that taps into the collective wisdom of educators and academicians “As with all assignments, I believe that holiday homework should be meaningful for students, give genuine feedback and build on prior learning, enabling them to scaffold their learning. “Unfortunately, too many instances of holiday homework are heavily reliant on parents and are completed in the last days of the vacation. Teachers, too, struggle to grade the projects or reams of worksheets and, as a consequence, the student comes to believe that this was not, nor will ever be, a worthy use of their time. “My most memorable holiday homework assignments: “At 11: I had to draw and colour in a map of the recently dissolved USSR during which I learned so much, primarily because my parents insisted…

The US Forest Service has commercial contracts for a fleet of 300 helicopters and more than 50 fixed-wing aeroplanes, which dump 40 million litres of fire-retardant sludge onto forest fires each year. But, surprisingly, there isn’t very good evidence that it works. A 2011 study found no correlation between the use of fire retardant and fire-fighting success rates. Once a wildfire is raging, airdrops seem to be more about public relations than effective firefighting.

seven earth-sized exoplanets found

DISCOVERIES DISPATCHES FROM THE CUTTING EDGE TRAPPIST-1, an ultracool dwarf star located just 40 light-years from Earth in the Aquarius constellation, was first detected by researchers from Liege using the Transiting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile, and later confirmed by NASA’s Spitzer Space Telescope and the Very Large Telescope, also in Chile. The planets were detected by observing dips in the star’s light output caused by each of the seven planets passing in front of it, events known as transits. The researchers found that all of the planets are comparable in size to the Earth, while density measurements suggest that the innermost six are rocky. Current climate models suggest the three innermost planets are probably too hot to support liquid water, and the one furthest from the star is…

DRONING ON Uber uses UAVs for ads As if the traffic wasn’t bad enough in Mexico City, these commuters have to put up with these ad-toting drones too. The slogans carried by the UAVs are urging people to use their cars less, and use Uber instead – the ad at the front says “This is why you never see the volcanoes,” a reference to the smog blocking out the vistas in the city. The makers of the ride-sourcing app see Central and South America as a key area for growth and, true to form, are utilising the very latest technology to get their message directly to potential users. While it’s a smart publicity stunt, we can’t help but worry about it catching on over here VIRTUAL REALITY You can touch this With the VR revolution…
