Why PDAs failed
|
view preview
I found this wonderful article online that seems to have been abandoned for some time now (source below), it's called: Timing of Entry from PDAs to Smart Phones: The Evolution of an IndustryDespite having innovative and sophisticated product designs, most of the early PDA companies failed. This was mainly because the success of PDAs was dependent on several aspects of enabling technology that had not been fully developed at the time a flurry of companies ventured into this sector. The success of PDAs was dependent on the invention of enabling technologies such as handwriting recognition software, modems, and power and memory miniaturization.

This isn't a fancy dessert

We know they kind of look and sound like a fancy dessert, but you won't find Little Egg Cowries on a dinner plate any time soon. In fact, you'll have a hard time finding them anywhere, because these spotty little sea creatures are masters of disguise. Through a process known as 'alimentary homochromy', they can change the colour, patterns, and shape of their flesh to perfectly mimic that of the coral and sea sponges around them.

This moon looks like a ball of cheese
|
view preview

Taken by the Galileo spacecraft, this image shows Jupiter's moon, Io, and its incredibly bright colours derived from sulphur and molten silicate rock. Io is covered in volcanoes that are so active, they effectively turn the whole moon inside out. And some of Io's volcanic lava is so hot, it glows in the dark.

Hunting for honey

view preview
This is what hunting for honey from a 90 metre cliff in Nepal looks like. This tradition has been held by the Gurung people of Nepal for thousands of years, and it's only going to get more dangerous, now that bee populations are dwindling around the world.

Stress alters children's DNA
|
view preview
Stress affects children too. Children who grow up in stressful situations have shorter telomeres, an early sign of genetic ageing that makes them vulnerable to diseases such as cancer. Telomeres shrink when cells divide, but when they get too short, the cell can’t divide and dies.
