Sphero 2.0 is the world’s first robotic ball you can control from a smartphone or tablet. It has over 25 apps available for iOS and Android, ranging from games to tools and lighting, and the device is cram-packed with tech. But with a sealed shell and no apparent moving parts, how does it roll? It all starts with inductive charging. In order to keep Sphero waterproof there can be no plugs, wires, or battery compartments. Instead, it has its own built-in batteries that are charged by passing energy through the shell itself. This is accomplished by a charging station containing a copper coil, which generates an alternating electromagnetic field. Inside the robot another copper coil converts that invisible field into electricity.</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px; text-align: justify;">
Once charged, a quick double-shake of Sphero is the command to ‘wake up’. This is when all of the robot’s electronics turn on, including its coloured LED lights, CPU and Bluetooth communication module, which allows it to talk to your smartphone. When a user starts the Sphero Drive app and touches the joystick, that touch is converted into a given speed and heading, which is then conveyed to the robot via Bluetooth. Sphero then rolls wherever the user directs it on their device.</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px; text-align: justify;">
Carefully packed inside the white shell is a tiny robot that uses a gyroscope to balance on two wheels. Think of it like a Segway stuck inside of a ball. Sphero might not look like it has a front or back, but the robot inside does thanks to the help of a gyroscope. When Sphero is commanded to drive in a new direction, it’s able to rapidly rotate to face the right way based on its position relative to the user. This all happens seamlessly inside the robot. To the user, Sphero rolls just like any other ball.</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px; text-align: justify;">
But, how does Sphero drive? In short, it drives like a hamster wheel spins. The robot drives up the side of its own shell just like a hamster runs up the side of its wheel. Of course, the hamster never gets anywhere. No matter how hard it tries to climb, gravity pulls it down and the wheel falls away beneath it. Sphero works the same way – constantly climbing uphill, scrambling up the side of its own shell only to have the shell roll out from under it – which causes Sphero to roll. In a sense, Sphero runs on gravity.</div>

Royal jelly is a milky white food that is secreted by glands in the throats of worker bees and fed to bee larvae. It’s named as such as it was once believed that this was only fed to those larvae in the colony destined to become queens. We now know that this protein-rich food is fed to all bee larvae in the colony, but larvae that are to become workers are fed small amounts and those to become queens are given an excess of this food.</div>

<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px; text-align: justify;">
People with defective eyesight can undergo laser- assisted in-situ keratomileusis (LASIK) eye surgery to correct their vision. LASIK involves using an ultraviolet laser beam to remove tissue and alter the shape of the cornea at the front of the eye.</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px; text-align: justify;">
If, say, the cornea is not perfectly spherical, light rays entering the eye won’t focus on a single point on the retina, causing diminished vision. However, by reshaping the cornea, light rays can be refracted (bent) as they pass through the cornea to focus light properly.</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
</div>
<div style="text-align: justify;">
A computer maps the shape of the patient’s cornea before calculating exactly how much tissue needs to be removed. Using a fine knife called a microkeratome, a flap is sliced on the surface</div>
<div style="text-align: justify;">
of the cornea and folded out the way. The main laser light doesn’t penetrate the eyeball, but rather it pulses, vaporising the tissue on the surface of the cornea. The flap is then folded back and heals without the need for stitches, resulting in instantly improved vision.</div>
<br />
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px; text-align: justify;">
The actual surgery takes a surprisingly short amount of time. From the point at which the numbing drops get popped in, the creation of a flap, reshaping and replacing it should take between 15 and 30 minutes, with full vision returning within 24 hours.</div>

What else can laser eye surgery do?</h3>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px; text-align: justify;">
Laser eye surgery is not limited to curing long and short-sightedness. Modern technology is also able to cure astigmatism, which happens when a person’s cornea is an irregular shape, which means light doesn’t enter the retina cleanly and is bounced about, resulting in blurred vision. The laser is able to reshape the cornea.</div>

The cornea in a short-sighted eye is bent too much, so when light enters, the image gets formed too early and becomes blurry when things are far away. The opposite applies to long-sightedness, as the cornea isn’t bent enough and the image hasn’t been formed by the time it hits the retina.</div>

What is 20/20 vision?</h3>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px; text-align: justify;">
We’ve all heard about 20/20 vision, but what exactly does that mean? Well, eye specialists have worked out how tall letters have to be for a normal eye to be able to see them at 20 feet (6.1 metres). Someone with 20/20 vision can see letters of that height from 20 feet, meaning their vision is just as expected. Someone with 20/40 vision can see something at 20 feet that a person with normal vision can see at 40 feet (12.2 metres). So, the bigger the second number, the worse the vision</div>

Experts from the University of Bristol are developing a type of a new type of education tool and information transfer: bubbles.</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
The new system, known as a ‘chrono-sensory mid-air display system’ will use a screen of water which displays messages on the bubbles. When popped, a particular scent will be produced. Primarily geared for use in education, the ‘SensaBubble’ will create a new type of learning style. For example, a clock could release the amount of bubbles to show the time, or fun and visual maths games could be created with a student popping a bubble which represents what they think is the correct answer. It would then release a different scent depending whether it is right or wrong. They could also be used in the office to show unread emails and missed calls and in shopping centres to help retail advertising.</div>

Imagine there are two identical twins; the first travels into space in a high-speed rocket, while the other remains on Earth. When the first twin returns he finds he has aged less than his Earth-bound twin.</div>
</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
<div style="text-align: justify;">
This happens because of something called ‘time dilation’ where, at high speeds, the faster something travels, the slower time passes for it.</div>
</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
<div style="text-align: justify;">
This effect is seen in global positioning system (GPS) satellites. As GPS works by precisely timing signals sent from the satellites to receivers on Earth, it is vital for the clocks involved to have a nanosecond (1 billionth of a second) accuracy. However, the satellites are travelling fast enough that time dilation occurs on the nanosecond scale, meaning the satellites are travelling through time at a slightly different rate to the receiver on Earth.</div>

Invisibility cloaks: Are they soon to become a reality?

<div style="color: #333333; font-family: roboto, sans-serif; font-size: 14px; line-height: 20px; text-align: justify;">
 For the moment Harry Potter’s famous invisibility cloak will remain in the realms of fiction, but significant steps have been made towards the very first real life invisibility. Researchers at the Lawrence Berkley National Laboratory and the United States’ Department of Energy have found a way of creating an ultra-thin, skin-like invisibility cloak that is able to conform to the shape of any object and conceal it from detection.</div>
</div>
<div style="background-color: white; box-sizing: border-box; color: #333333; font-family: Roboto, sans-serif; font-size: 14px; line-height: 20px; margin-bottom: 10px;">
<div style="text-align: justify;">
Sound brilliant right? The only difference between the multitude of sic-fi cloaks and this real life contraption is that currently it only works at a microscopic scale. Having said that the principle behind it has huge potential, and should be able to be scaled up to a macroscopic scale.</div>

<div style="text-align: justify;">
An invisibility cloak isn’t the only thing this technology could one day give birth to. Being able to manipulate the way light interacts with metamaterials could open the door to high resolution optical microscopes and super fast optical computers.

<div style="text-align: justify;">
Sphero 2.0 is the world’s first robotic ball you can control from a smartphone or tablet. It has over 25 apps available for iOS and Android, ranging from games to tools and lighting, and the device is cram-packed with tech. But with a sealed shell and no apparent moving parts, how does it roll? It all starts with inductive charging. In order to keep Sphero waterproof there can be no plugs, wires, or battery compartments. Instead, it has its own built-in batteries that are charged by passing energy through the shell itself. This is accomplished by a charging station containing a copper coil, which generates an alternating electromagnetic field. Inside the robot another copper coil converts that invisible field into electricity.</div>
</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
<div style="text-align: justify;">
Once charged, a quick double-shake of Sphero is the command to ‘wake up’. This is when all of the robot’s electronics turn on, including its coloured LED lights, CPU and Bluetooth communication module, which allows it to talk to your smartphone. When a user starts the Sphero Drive app and touches the joystick, that touch is converted into a given speed and heading, which is then conveyed to the robot via Bluetooth. Sphero then rolls wherever the user directs it on their device.</div>
</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
<div style="text-align: justify;">
Carefully packed inside the white shell is a tiny robot that uses a gyroscope to balance on two wheels. Think of it like a Segway stuck inside of a ball. Sphero might not look like it has a front or back, but the robot inside does thanks to the help of a gyroscope. When Sphero is commanded to drive in a new direction, it’s able to rapidly rotate to face the right way based on its position relative to the user. This all happens seamlessly inside the robot. To the user, Sphero rolls just like any other ball.</div>
</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
<div style="text-align: justify;">
But, how does Sphero drive? In short, it drives like a hamster wheel spins. The robot drives up the side of its own shell just like a hamster runs up the side of its wheel. Of course, the hamster never gets anywhere. No matter how hard it tries to climb, gravity pulls it down and the wheel falls away beneath it. Sphero works the same way – constantly climbing uphill, scrambling up the side of its own shell only to have the shell roll out from under it – which causes Sphero to roll. In a sense, Sphero runs on gravity.</div>

  The year is 2113. Humanity has spent the last 100 years stockpiling nuclear warheads. And not just a few – 600 billion of the largest, biggest, deadliest warheads they can build. Sort of like the <a href="http://www.howitworksdaily.com/video-worlds-biggest-nuclear-bomb/" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; box-sizing: border-box; color: #428bca; text-decoration: none;">Russian Tsar Bomba</a> (the biggest nuclear bomb ever detonated) but, well, times 600 billion.</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
Why? Because we’ve decided to blow up the Moon, and to do so would require the equivalent of 30 trillion megatons of TNT.</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
When we say blow up, we don’t just mean slightly-blow-up. See, if you don’t completely obliterate the Moon, the remaining fragments will likely coalesce back together into a Moon-sized object. Sure, it won’t look as pretty or as spherical as our modern Moon, but it will be pretty similar in its gravitational effect on Earth.<br />
No, what we (or, more specifically, our future selves) want to do is completely get rid of the Moon. So, with their multiple rockets ready and waiting to attack the Moon from all sides, they launch them towards our natural satellite and blow it to smithereens. Scientists around the world eagerly prepare for one of the greatest (and most idiotic) experiments of all time.<br />
With the fragments of the Moon too small to gravitationally bond together, they begin to spread out. First, a large number of them head towards Earth, raining molten Moon rock down on our planet. Cities are destroyed, countries are wiped off the map, and we begin to wonder if blowing up the Moon was such a brilliant idea.<br />
The remaining Moon material enters orbit around the world, forming a ring around our planet. But, like Saturn’s ring, it doesn’t just stay there. Periodically, for the rest of Earth’s life, meteorites break from the ring and slam into the surface. We’re now under constant bombardment from an apparently vengeful Moon.</div>

  But the Moon isn’t quite done getting even yet. Have you ever noticed that the Moon is covered in craters? Well, that’s because it gets pounded by meteorites, protecting Earth from some of the rocks that head our way. With the Moon annihilated, we’re now also more vulnerable to space rocks.<br />
Of course, one of the Moon’s most noticeable effects is (or was) the tides. With the Moon no longer there, the oceans of the world become much calmer. The Sun still has an effect on them (known as solar tides), so surfers wouldn’t be completely devoid of waves. But the oceans would largely become serene.<br />
This has a dire effect on life on Earth. When life first formed on Earth in tidal pools, it was thanks to the gravitational pull of the Moon that primordial life was able to traverse between different pools and generally spread across the planet. While we’re already here now, life that is currently in the oceans is no longer able to move so easily. The churning of the oceans, and thus the circulation of nutrients, ceases. Water-based life struggles to survive and, eventually, thousands (and probably millions) of species go extinct.<br />
The Moon isn’t done yet, though. You see, it also accounted for about one-eightieth of the Earth-Moon mass system. The loss of the Moon directly affects the Earth’s orbit, rotation and wobble. Without the Moon to act as a stabiliser, the Earth begins to wobble more and more, sending <a href="http://www.howitworksdaily.com/what-would-happen-to-our-weather-without-the-moon/" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; box-sizing: border-box; color: #428bca; text-decoration: none;">our seasons into turmoil</a> and changing our orbit around the Sun from slightly elliptical to massively elliptical. We now swing around the Sun in a wild, unstable, fluctuating orbit.<br />
As the world regrets their ill-advised decision to destroy the Moon, it’s already too late to do anything. If humanity survives the constant bombardment from the remains of the Moon and other space rocks, the eradication of most other species from the globe, and finally the potentially catastrophic seasonal changes then, well, maybe blowing up the Moon wasn’t such a bad idea.</div>

We’ve all been there. Halfway to the airport and suddenly gripped by the unshakable fear that we’ve forgotten to switch off the oven or lock the windows. With a smart home, you can put your mind at rest and fix any little oversights, all from your phone as you speed toward your flight.</div>
</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
<div style="text-align: justify;">
In a smart home, all the electronic devices are connected to one another in one controllable network, allowing inhabitants to interact with their homes like never before and offering greater comfort, convenience, personalisation, energy savings and opportunities for fun!</div>
</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
<div style="text-align: justify;">
Want your coffee maker to crank up downstairs as soon as you throw back your sheets? A smart home will let you arrange that. Want to start the bread maker churning and the pool heating as you leave the office? You can do that too. Want your home to learn your habits and help cut your energy consumption, or to notify you if it senses anything untoward like an intruder? No problem at all.<br />

<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
<div style="text-align: justify;">
The basis for all these technological advances is the ‘Internet of Things’ – the exponentially expanding web of devices that are connected to the Internet, allowing them to talk to each other and to you, transforming the way we live.</div>
</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
<div style="text-align: justify;">
Automated home electronics have been on the scene for decades, but only recently have they been able to begin talking to one another and functioning in concert. That’s largely thanks to the advent of efficient low-cost wireless protocols – think Wi-Fi, Bluetooth, mobile phone networks – in the early-2000s, which use radio waves to transmit messages wirelessly.</div>
</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
<div style="text-align: justify;">
ZigBee and Z-Wave are similar protocols that can be thought of as low-power versions of Wi-Fi. They are ideal for use inside the smart home because they’re optimised for transmitting small amounts of data – like messages to and from smart devices – through walls and furniture, over the range of a typical household.</div>
</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
<div style="text-align: justify;">
Smart devices are connected via these wireless networks to a central hub where they can be controlled with a tablet or smartphone. They can also be programmed to carry out any action based on the logic command ‘If This Then That’, or IFTTT (rhymes with lift). IFTTT lets you dictate what action a device should take for a given stimulus.</div>
</div>
<div style="box-sizing: border-box; font-family: Roboto, sans-serif; margin-bottom: 10px;">
<div style="text-align: justify;">
For example, announcing to your TV, “It’s movie time”, might lower the shades, dim the lights, activate your surround sound system and fire up the popcorn maker. Now that’s smart.</div>
