Emerald Robinson: New developments in understanding Stonehenge, fruits and veggies might be the key to happiness, and the fall of the almighty PC. Get ready to move at the speed of light on today's Daily Orbit!
Hello and welcome to the Daily Orbit! I am Emerald Robinson.
Stonehenge has long been a mystery to archeologists and laymen alike, with its unique design and unknown origins, it envelopes us in an old world of myth and superstition. New high-tech laser scans have revealed more secrets of the site. The scan's data show that the stones were deliberately arranged from the northeast, up the avenue, and towards the direction of the midwinter sun, with the smoothest, neater rocks facing the summer and winter solstices.
The scan also led to the discovery of 71 Bronze Age axe heads carved into the stone. Researchers say the scan disproved ideas that some of the cracks were prehistoric carvings and revealed they were due to natural weathering. Don't you just love ancient mysteries?
And a new fossil discovered in China shows that anatomically complex brains evolved earlier than previously thought. The find is the earliest known fossil to show a brain and suggest that the brain hasn't changed much over time. Deposited in the Cambrian period about 520 million years ago, the fossil's subject belonged to a type of arthropod that had an advanced brain with a primitive body. Arthropods are the taxonomic group that is comprised of crustaceans, arachnids, and insects. Scientists are calling it a "transformative discovery" as the find resolves an old debate on how and when complex brains evolved.
And now I am just waiting for a few human brains I know to evolve.
And what does this next story say? Eat your fruits and veggies! I feel like we are constantly bringing you new research on the benefits of eating healthy. Turns out these power-packed foods do more than keep your body healthy, they are good for mental health as well. A new study confirms that each serving of fruits and veggies you eat increases mental well-being and overall happiness. What's the optimal number to eat for ultimate happiness? That's seven portions a day, but that's the max; there is no increase in well-being found after that. Scientists are sounding a little like mom, don't you think?
And PC may soon stand for Positively Colonial as the popularity of smartphones and tablets outshine the old personal computer. Global shipments of personal computers are set to fall for the first time in 11 years. According to projections the market could drop from 352.
8 million units in 2011 to 348.
7 million units this year, marking the first drop in this market since 2001. PC makers are optimistic that the release of Windows 8 and the new Ultrabook computers will bounce them back in 2013. However, analysts say that the sale of smartphones and tablet devices will likely surpass the sale of PCs by 2016. They are just so much easier to fit in my purse.
Nothing can move faster than the speed of light, right? No say some scientists who believe their new mathematical formula allows for travel beyond this limit. Their new formula extends Einstein's special relativity, eliminating the speed of light as an absolute. But researchers say getting from the theory to any practical test is another matter entirely. That's ambitious, correcting Einstein!
Well, that's it for the Daily Orbit, see you tomorrow! Catch me if you can!
