After Google Glasses were revealed there was a lot of speculation as to just what the technology giant was going to do next. The answer, many were shocked to find, is that the Internet and technology giant is creating contact lenses. They won't be used to browse the Internet though; the lenses, if all goes according to plan, will be used to revolutionize the way diabetics live their lives.
Sugar-Sensing Contact Lenses
People who live with diabetes have difficulty maintaining a healthy blood sugar level. This leads to all kinds of medications, lifestyle changes, and other preventative measures being taken to help control the condition. One of the most common sights though is a diabetic person jabbing his or her fingertips, swabbing a bit of blood onto a test strip, and then inserting the strip into an electronic reader to check the glucose levels in the blood.
Google might be eliminating the need for that kind of testing
The contact lenses currently being tested have tiny, miniature LED lights that look like specks of glitter when worn. Sandwiched between layers of the lens, the technology measures glucose levels in the wearer's tears. When the levels get too high, or too low, the LED lights flash to warn the wearer of the condition. There's no pricking necessary, no need to carry test strips, and less of a package to carry around when leaving the house.
The question people might ask, and legitimately so, is at this point is what's next? If contact lenses can be fitted with circuitry and worn with little to no effort, then what else is possible? Will futuristic technology be installed directly into affected tissue to cure diseases from the common cold to cancer? Will the cell phones and iPods of the future be able to catch ambient brain waves to charge themselves? Or, for that matter, will people be able to download information straight into their brains?
We're not there yet, but the keyword in that sentence is yet. Things once thought completely impossible, such as cybernetic prosthetics capable of delivering sensation to the brain, have become common. Still cutting edge, but fairly common all the same. When it comes to Google's revolutionary contact lenses, the question is really what other conditions can be monitored and treated using this tiny technology? The miniaturization of medical monitors might result in a complete change in how conditions are diagnosed and treated. They could also lead to test results being completed in minutes, rather than in hours or days as has been the case previously. Only time will tell for certain.

After you've recovered from an injury you will find that there is still a way to go before you get completely back to normal. If you've had a damaged spine, damaged limbs or another kind of bone, joint or muscle problem, then you will probably be advised by the doctors to try and strengthen the damaged body parts in order to give the area more support and to help retrain the muscle around it that may have wasted away from lack of use. It's crucial that you do this in order to avoid further injure that can result from muscle imbalance, and to make sure that you recover as quickly as possible. At the same time though, it can also be quite difficult – using your weakened limbs is hardly easy when there's barely enough muscle to lift then and you are going to be weary of causing yourself pain or re-damaging the damaged area.
Fortunately though there are a few ways around this problem, and a number of gadgets and gizmos that can help you in your aim. Here we will look at some of the technology that can help you retrain your muscles and get back the strength and definition that you may have lost.
Electric Muscle Stimulators

Electric muscle stimulators work by generating lots of tiny little electric shocks delivered through moistened pads that you strap to your various body parts. The idea of this is to send signals to your muscle fibres (all our cells communicate through electrical impulses) which will then cause them to fire resulting in your muscles tensing. Since it's the act of tensing that trains your muscles, this is a great way to grow them without actually training and can help you to firm them up while you're not actually lifting weights or running on the treadmill.
Of course these machines aren't really as good as actually exercising – otherwise everyone would use them and everyone would be massively ripped – but they are a great alternative while you're in recovery.
If you have a back injury and you're being encouraged to move around, then you may be in need of some kind of analgesic to make your activities less painful and more bearable. Tens machines can provide just that, and work in the same way as the above electrical pads by sending jolts of electricity through your skin.
Only the difference here is that this time you're wearing the pads on your back around the sciatic nerve, and the idea is to stimulate the surrounding tissue to create a tingling sensation. This can act as 'noise' which disrupts the feeling of pain coming from the nerves in that area. The machines are even used by women giving birth, which should give you an idea of how useful they can be.
A power ball is a small plastic ball with a wheel inside that spins around when you shake your arm in the correct motion. This wheel inside is actually a gyroscope which means it's capable of exerting great amounts of pressure on your wrist while you shake it – though not so much as to aggravate any injuries. It’s a great way to build up strength in your arms and potentially to rehabilitate a broken forearm or wrist – but do check with your doctor before trying this one in case you're risking exacerbating the problem.
Recumbent Stationary Bike
Stationary bicycles are great machines for working out the muscles in your legs and burning calories by letting you do CV. They create zero impact, meaning they won't hurt your joints, and they don't require any space if you have on in your home.
The problem with most bikes though is that they require you place weight on your legs and spine which can be a problem if you have an injury. The recumbent bike gets around this by allowing you to lie back and cycle with just your legs. It's highly effective for training muscle without placing any strain on your various bodyparts.

For years contact lenses have allowed us to throw off the eyeball oppressing dictator known as the spectacle, exposing our beautiful visages to the world in all their natural glory - but what if contact lenses allowed you to do more than simply avoid the embarrassment of running into the arms of a stranger at the station?
Contact lenses that help enhance normal vision are now being designed by scientists using military funding, so you could one day peruse Facebook right before your eyes while boiling an egg in the morning.
The thinking behind this technology relates to the miniaturisation of displays and the fact that there has to be a limit to this process: “One of the limiting factors in further shrinking the size of electronic devices, say a laptop, is the display size,” says Babak Parviz, associate professor of electrical engineering at the University of Washington and leader of the study, told INO. “Below a certain size, displays are not really usable for the human eye. We wanted to see if we can de-couple the display from the rest of the device, allowing everything to get much smaller.”
A remote radio-frequency transmitter powers the display. Built into the lens are an antenna, a small radio and a light source - in this case, the single pixel. Once higher-resolution displays are developed, the researchers say this technology could be used for web browsing and video games, to provide visual warnings for the hearing impaired, or in various forms of training for military professionals. Indeed, researchers are even looking to develop hi-tech lenses that will feed battle field information directly into the eyes of military soldiers.
This technology could also be used medically. Sensimed, a Swiss medical equipment company, has been using similar technology with its Triggerfish contacts, which have already entered the market. These contact lenses, which also contain microscopic antennae, are designed to track changes in pressure within the eye. This information warns the wearer whether they show signs of possible glaucoma, one of the leading causes of blindness.
Indeed, the potential uses are countless, and include immersive video, 3D gaming, mobile device interfaces, and augmented reality applications layering computer imagery over what we see in the “real world”.
While some of these applications are clearly very useful, we have to ask ourselves if we really do need real time information feed straight into our eyes. The internet is restructuring people’s brains and shortening our attention spans, so could this be another unwelcome step towards an increasingly technology-stressed human mind?
But let’s stay positive, a brave new world awaits us as human thinking and creativity moves inexorably forward. In a couple of years, you may even be buying visual contact lenses from your contact lens retailer, as quickly as you would buy your daily disposables. With all these distractions, it’s important to remember - as exciting as it may be to watch your favourite show while walking down the street, don’t let it distract you from any open manhole covers!

The rising cost of power might be a thorn in the side of every consumer but the ever-improving solar power industry certainly represents a comforting light at the end of the tunnel.
Today, the feasibility of solar power is a globally recognised solution that’s been adopted by everyone from home owners and small businesses to large conglomerates around the world. Technology to harness the power of the sun first emerged in the 1860’s and was later put on hold due to the mass availability of coal and petroleum. Due to a 1973 oil embargo and a 1979 energy crisis, however, attention was once again put on the development of solar technology – and thank goodness it was. By the early 80’s photovoltaic or solar cell installations experienced rapid growth and since the 90’s, due to oil and natural gas supply issues and global warming concerns, the solar industry has simply been sky rocketing.
The sheer impact of solar power energy on the planet is undeniable and if today’s standards are anything to go by, it seems set to play a momentous part in the future of world-energy. Some notable solar energy projects include:
Gujarat Solar Park in India
This is the name of a group of solar parks being constructed in Gujarat in India that are set to be complete sometime in 2013. It’s been estimated that the park will collectively be responsible for saving around 8 million tonnes of carbon dioxide from being released into the atmosphere. And each year, it will save about 900 000 tonnes of natural gas. State of the art facilities like this are setting the bar high for businesses around the world when it comes to energy, and it’s an attractive prospect for investors too.
Solar energy to be main energy source for Gulf countries
Clean, renewable sources of energy are taking centre stage in countries like Saudi Arabia, Qatar and United Arab Emirates. It’s recently been estimated that solar power energy will be the Persian Gulf’s main source of energy by 2017, with 155 billion dollar’s worth of installation projects currently underway. Experts from the international solar power industry are currently being called in to make decisions about the challenges that come with solar constructions in desert terrain.
Solar powered wheelchairs
We’re already using solar power for things like traffic lights and water heating, but a group of students in the USA took it to a whole new level when they invented a solar powered wheel chair during a competition held for World Cerebral Palsy Day. The invention, which includes a USB port and a GPS navigation system, won the students the competition – and an invention disclosure has been filled out for the product. We may very well see it being manufactured sometime soon.
If the future of solar is a prospect that excites you, we’d recommend starting in your very own home. Installation professionals are readily available and can have you saving on your power bills significantly with their smart solar power solutions.

Throughout history we have been blessed with some great thinkers, people who have started a train of thought that others could not have envisioned before them. Below are some of the scientists I feel have shown themselves to be the greatest thinkers in history; people who have lead the way for others to follow.
Sir Isaac Newton
Perhaps the most brilliant scientist ever, Newton was a master of many fields of science and mathematics. He made breakthroughs in fields including astronomy and philosophy, but is probably better known for his work with gravitation and laws of motion. Between his own laws and the laws laid down by Kepler, he showed the world the reasoning behind why planets moved as they did and objects fell to earth. Many people think that his Philosophae Naturalis Principia Mathematician is the greatest scientific book ever written, and took Newton years to complete. Sir Isaac could have made this list many times over, but putting him at the top of my list should be enough for this truly influential man.
Leonardo da Vinci
Although more famous for his works of art, such as the Mona Lisa and the Adoration of the Magi, da Vinci was also an inventor and thinker who was far ahead of his time. His scientific contributions were mainly theoretical at the time, but being able to envisage tanks and helicopters shows the vision he had. He also was one of the first to appear to understand the human circulatory system and plate tectonics. Leonardo da Vinci was a visionary who was too far ahead of his time to see his thinking enter the mainstream, but still ranks as one of the greatest thinkers in history.
As child who underachieved at school, Albert Einstein certainly made up for it in later life. Einstein revolutionized science, and made us look at the physical world through different eyes. This genius who wrote 300 scientific works, contributed theories including the Special Theory of Relativity and the Quantum Theory, both of which had far reaching implications. The fact that is probably the most famous equation in the world, and the term Einstein is now used to denote intelligence, shows the impact this great thinker has had.
No scientist caused more controversy with their work than Charles Darwin. His theories as laid
out in On the Origin of Species by Means of Natural Selection, put forward an argument that disputed the truth of Man as created by God; and this caused uproar around the world. But his study of how life has developed has been shown to be a truth that cannot be denied. He argued that natural selection had driven the development of all living things, and felt this explained the differences between species that lived in different habitats. The debate may have raged for years, but in the end Darwins work has been revered as a brilliant piece of thinking backed up with research.
These men of science were ahead of their time, and showed us that real thinkers will find the truth no matter what the current thinking is. Being able to think outside the box and then prove your theory is the measure of true brilliance.

How do satellites work?
The first satellites may only have been launched into orbit less than 60 years ago, but many facets of the modern world and day-to-day life have come to depend on their presence.
Although the term ‘satellite’ also refers to natural objects in Earth’s orbit - the Moon in particular - it has come to be generally associated with artificial satellites sent into orbit to perform a variety of tasks, which are facilitated by the high vantage point and being outside interfering elements of the Earth’s atmosphere.
The first satellites
The Soviet Union was the first country to succeed in establishing an orbital satellite when Sputnik I was launched on 4 October 1957, shortly followed by Sputnik II that carried the first living creature, the dog Laika, beyond the Earth’s atmosphere.
The Sputnik launch is commonly viewed as the major catalyst in the Space Race that ensued between the USSR and USA, but it also inspired people around the world as possibilities that were previously consigned to science fiction started to become more tangible.
The United States launched its first satellite, Explorer I, in January 1958, which discovered the presence of magnetic radiation belts around the Earth and was succeeded by other satellites in the Explorer program designed for scientific research. This led to the establishment of the National Aeronautics and Space Administration (NASA) later that year.
Communication satellites are primarily responsible for sending and receiving radio signals to and from points on the Earth’s surface, and this is accomplished in a number of ways. The simplest satellites reflect or ‘bounce’ these signals at greater strength than they were received, and can convert the information into different frequencies and data, where it will be received by antennas on the ground. These may be large earth stations that broadcast signals over a wide area, such as radio and television towers, or compact antennas inside mobile phones and other devices.
Satellites do not broadcast signals indiscriminately, and are designed to send and receive information according to specified geographical locations. By working on dedicated frequencies, satellite users can also ensure that signals will not be mistakenly picked up by other receivers.
A number of orbiting satellites were designed for carrying out scientific and meteorological research. Weather satellites monitor changing cloud patterns, fluctuations in pressure and temperature levels and other factors to predict likely weather events, and have proven invaluable in providing early warnings for natural disasters such as typhoons and hurricanes.
Other research satellites are concerned with different aspects of the Earth, such as changes in the atmosphere or terrain, while others direct their attentions away from the planet entirely to study outer space. One of the most notable of these is the Hubble Space Telescope, which has taken some of the most spectacular images of the universe that would not have been possible from the Earth’s surface.
More breakthroughs came in the area of navigation, as satellite technology became ever more sophisticated and capable of pinpointing accurate locations on the Earth’s surface. This technology revolutionised search and rescue operations and eventually trickled down to passenger vehicles, many of which can now benefit from comprehensive maps, directions and real-time traffic updates.
The first satellite dedicated to communications and entertainment was Telstar 1, which was launched in 1962. It made the live broadcasting of global news events, sports and other TV shows possible for the first time.
This basic satellite laid the groundwork for others that followed in Telstar’s wake, which made long-distance telephone calls and household satellite TV broadcasting a reality - these satellite services are of course now common place. HBO was the first television network to offer satellite TV services to subscribers in 1975, and satellites became the primary means for broadcasting by the 1990s.

The work you do in your laboratory can only be done if you have the right supplies and the proper safety procedures in place. Not having a properly stocked and safe lab could spell disaster for any research project or team in an instant. No matter what work you are doing in your particular lab, chances are you will be exposed to any number of hazards, and you have to be sure you and those working in your lab are prepared to deal with these dangers in a safe and effective manner. Here are some tips to make sure your lab is safe.
Following Federal Standards
There are more than 500,000 laboratory workers employed in the United States, according to the United States Department of Labor. In order to protect these individuals, there are federal safety requirements in place, as well as state and local regulations, all of which must be followed in each lab. These rules are set to protect lab workers from the potential hazards they face each time they set foot into a lab. The federal regulations under OSHA deal specifically with:
- Exposure to hazardous chemicals
- Air contaminants
- Bloodborne pathogens
- Controlling hazardous energy
- Protection of the eyes and face
- Protection of the respiratory system
As well as a host of other safety regulations, all of which can be reviewed on the Department of Labor website.
Knowing How to Handle Different Emergencies
Part of working in a lab means knowing how to handle all of the ‘what if’ situations that may arise. For example, in a lab one could encounter many different kinds of emergencies ranging from chemical spills to fires. Those working within the labs should be trained to handle all of the potential situations as well as how they can best help their coworkers should they be in need of assistance. That means, whenever you have someone new come on to your team, you should be sure that they know how to respond to medical emergencies, fires, chemical spills, radioactive spills, and biohazard spills.
Having the Right Supplies
Of course, you can have all the safety measures and protocols in the world in place and they will mean nothing if you do not have the right laboratory supplies. A properly stocked lab with the right equipment for any given test or procedure will help to ensure your staff is protected while they do their work. Using the wrong tools as tests are preformed could create a dangerous, even deadly situation that could have been avoided if the right equipment had been available.
Having a well-functioning lab means being proactive in your preparation for an emergency. If you are not prepared to deal with an emergency, it could spell disaster for your lab and those who work within it. Be sure that each of your lab employees are aware of the safety regulations, have been prepared to deal with emergencies, and have the right equipment to do their job and your lab will be that much safer.

Whether you are an undergraduate college student fulfilling a course requirement for graduation or a scientist with years of experience, it is always a good idea to have a comprehensive working knowledge of general laboratory safety. The best source of this safety information is your professor, supervisor, or the risk management department for your institution. Below is a list of safety tips that any scientist should be aware of before entering a biological laboratory, regardless of their level of expertise.
Tip 1: No food or drinks should enter the research space, nor should cosmetics be used. This rule protects researchers from potential harm and minimizes the chances of an experiment being contaminated. Walk into any well-run research department in the life sciences and you will find rooms set aside for food and drink, refrigerators for storing edible perishables, and even kitchens for food preparation.
Tip 2: Upon entering a laboratory for the first time familiarize yourself with the location of the safety equipment. Pay particular attention to fire extinguishers and what types of fires they can be used on. Other important safety equipment includes eye-wash stands, showers, and chemical fume hoods.
Tip 3: Personal protective equipment (PPE) should be readily available for use whenever the need arises. The primary PPEs in a biological laboratory are safety gloves, lab coats, safety glasses and goggles, and face shields. In a modern biological laboratory PPEs help researchers protect themselves and their personal clothing from hazards, while protecting experiments from contamination.
Tip 4: The clothing worn under PPEs should also have safety in mind. Researchers should minimize the amount of exposed skin, thereby minimizing the risk of burns due to chemical spills and splashes. For this reason, sandals and open-toed shoes are a no-no and pants are a better choice than shorts.
Tip 5: A working knowledge of chemical safety is another essential skill for researchers. For example, using glass containers for acids and plastic containers for bases can prevent burns and chemical fires.
Tip 6: Every laboratory will have established protocols for handling biohazardous materials safely. These protocols will cover the use and disposal of human blood and tissue products and microbial organisms.
Tip 7: Another major safety concern in biological laboratories is sharp objects, including razor blades, needles, and broken glass. All laboratories will have guidelines covering the proper handling and disposal procedures for these sharp objects.
Tip 8: Most biological laboratories will have multiple sources of heat that could be the cause of serious injury. Some of the most common heat sources are Bunsen burners, hot plates, PCR machines, and water baths. This equipment should always be used in a manner that minimizes injury to self and others.
Tip 9: Never taste, smell, or mouth pipet a chemical or substance without express permission to do so.
Tip 10: Keeping the laboratory and the personal research space clean and well-organized is an excellent habit, because it minimizes the chances for unintended chemical reactions, fires, and contaminations that can ruin an experiment. Contamination is a safety concern because it forces the researcher to repeat the experiment, thereby doubling the researcher’s exposure to possible injury or harm.
Observing these and other safety tips will minimize the researcher’s risk of injury and increase the chances of producing good data. A good grade in a laboratory course or a successful career as a biologist therefore depends on a thorough understanding of laboratory safety.

In the field of medicine, technology remains in a state of growth and development. The Internet and robotic technologies have allowed for long-distance surgeries. Virtual reality simulators are being used to treat patients’ phobias. And heart valves have never been more effective. The following five technologies showcase the cutting-edge of the medical field.
1. The ITClamp
Created by Canadian Naval surgeon Dr. Dennis Filips, this device functions in a similar manner as a hair clip. After serving in three tours of the Middle East, Flips found that many soldiers were dying from injuries, such as in the abdomen that could not be stopped with a tourniquet. Rather than holding back hair, this device clamps wounds and contusions shut, stopping blood loss quickly.
2. Microfluidic Flu Chips
Researchers from Harvard, Boston University, and Beth Israel Deacones have created a microfluidic chip designed to diagnose the flu in a fraction of the time spent using traditional methods. This disposable chip, which is the size of one of the microscope slides you used in your high school biology class, is interlaid with channels for mucus to pass through. The chip detects RNA signature proteins from the influenza A virus, converts it to DNA, and replicates it until an external reader can detect it. The researchers are currently developing a 2.0 version, which will provide patients with results in under an hour.
3. Implanted Medical Devices
In the past few years, implanted medical technologies have shrunk from silver-dollar sized pacemakers to micro machines small enough to be swallowed in a pill or injected into our bloodstreams. Although this is not Nano technology, engineers at Stanford are developing implants that will be able to navigate through veins and arteries in order to remove blood clots. As if that is not impressive enough, these tiny bots will be powered from electromagnetic radio waves—that’s right, no wires attached.
4. iPhone and the Medisana ThermoDock
Due to their interactive features, universal Internet access, and array of apps, the iPhone and iPad have been used in health information technology for several years. Now doctors can take temperatures from a distance using infrared technology that plugs into their iPhones. It functions like a point-and-shoot camera, and will replace the old fashioned, thermometer approach.
5. Artificial Skin
Wound management specialists are using technology to extract collagen, a fundamental skin protein, from donated skin. They then grow grafts of collagen, which they place over wounds of burn victims, soldiers, and diabetics. The body grows skin tissue around the collagen, which allows patients to recover from wounds that would otherwise require amputation.
The promise that emerging technologies provide for the future exist as a constant source of inspiration and hope. The ways that medical technology has shaped the world in the past 50 years serves as an example of what we can expect in the future: longer lives, less disease, and faster healing for many injuries. For a cutting edge career in the medical industry, consider a health care degree like practical nursing or medial assisting to get you started.
