The thought of how surgery will look in the future is something millions of people are always discussing. The amount of hours spent on surgery certainly can take a toll on a doctors schedule. If the population increases, how will doctors be able to keep up with more surgeries? Here is a post from CNN.com discussing the possibilities of surguries in the future:

LONDON, England (CNN) -- Over the past 20 years, robotics have revolutionized surgery, and new innovations are continuing to push the boundaries of medicine.

The "da Vinci" system revolutionized keyhole surgery.

 Mike Rustic, senior lecturer at the mechanical engineering department at Imperial College, London, says machines such as the "da Vinci" system have had a huge impact on surgery.

The "da Vinci" first appeared in 1991 and lets surgeons carry out keyhole surgery remotely, allowing them to control robot arms from a console that also provides a three-dimensional image of the proceedings.

While the "da Vinci" system is the most widespread robotic surgery tool, Rustic says the "Sensei Robotic Catheter System" is also starting to be used for electrophysiology procedures on the heart.  Take a look at the past, present and future of surgery »

A new exhibition at London's Royal College of Surgeons called "Sci-Fi Surgery: Medical Robots" has displays ranging from the "da Vinci" system to prototype microbots designed to be swallowed and self-assembled in the human body.

Rustic says there is much ongoing research into micro machines -- miniaturized robots that could be placed in a patient's body to gather information or carry out medical procedures.

But he says that although pill cameras -- cameras that are swallowed by a patient to provide images of their digestive system -- are already in common use, micro machines remain some way off.

"Micro machines are basically one of the holy grails, but it will take a while before we see something," he told CNN.

"The difficulty is that even if you can make little motors you need to power them up and you have to be able to communicate with them and direct them."

Rustic says one innovation on the horizon is a device being developed by Imperial College that would allow a surgeon to remotely control an endoscope while a patient is inside a Magnetic Resonance Imaging (MRI) machine, which would give real-time image feedback during gastric procedures and prostate biopsies.

But he adds that currently, robotic surgery devices are often prohibitively expensive and tend to be used for a narrow range of procedures. He told CNN that he would like to see an economical robot that can be reconfigured to perform a wide range of procedures in a standardized way, so that training can be simplified.

"There is currently a gap. We are trying to produce complex machines to replace surgical tools, which are hand tools. It's like when industry moved from a chisel and hammer to machine tools."

Pier Cristoforo Giulianotti is a professor at the University of Illinois department of surgery. He told CNN that as more manufacturers join the medical robotics marketplace, innovation will speed up and prices will come down.

He sees the future as bringing extreme miniaturization of tools, as well as developments in augmented reality, where visual displays show computer-generated images and information overlaid onto images of the real world.

Giulianotti cannot foresee a time when robots replace surgeons, but he has no doubts over the importance of robotics. "Robot surgery is the future of medicine," he said.

Have you been trying to figure a way to save a little bit more money each month? Well, you have come to the right place! Check out some of the small ideas below and start implementing them to save some extra cash each month.

   1. Brew your own coffee. Seriously, 3 bags of beans can get you through the month for a total of $20. Buying a cup every day would run about $4 for you, times 20 work days = $80 minimum per month.

   2. Put electronic equipment on power strips. You would be amazed at how much juice your unused equipment uses.

   3. Use a movie service like Neflix for $8.99 per month where you get 1 rental and unlimited computer viewing or console to television streaming. considering that renting from the store is about $5.00 per movie, and the movie theater costs $10, this is quite a deal. Plus, you don't have to drive anywhere, which saves money on gas.

   4. Buy fruit and vegetables at the local Farmer’s Market if you have one. It has been known to be  fresher and cheaper.

   5. Pay more than the minimum on your credit cards, auto loans, mortgages, etc. Every little bit helps in the long term when you are paying interest.

   6. Coupons for items that you do use regularly can be a blessing and save you lots of money. The lesson here is only getting things you need with coupons, it might take some searching but it can be beneficial.

   7. Buy a BRITA or PUR water filter and attach it to your faucet. The onetime expense of $20 gives you about 3 months of free filtered water, that most of the time you find is just as good as the bottled stuff you pay a fortune for.

   8. Go to the library to save money on buying literature to read, such as books and magazines. If you constantly are buying books and have nothing to do with them, you can always sell them to half priced book stores or donate them to libraries.

   9.  Take your lunch to work or school, which does call for buying groceries or preparing it the night before. If you or your family constantly has leftovers from the night before, packing your lunch shouldn’t be a problem.

  10. Buy generic medicines for Tylenol, ibuprofen, etc. The generic brands are just as good as the name brands and can be extremely less expensive.

Buying implementing some of these ideas, you will see the dollars literally fly back into your wallet or purse! If you have any other ideas or tips on how to save other money, give us a shout back because we want to hear from you!

A light-year or light year (symbol: ly) is a unit of length, equal to just under 1013 kilometers. As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian Year. A light year to the naked eye is looking a year in the past, which looking to the stars is looking to the past. A recent post by cnn.com has reported an image captured by the Hubble Space Telescope being titled as the "Butterfly Nebula". The picture below is of the image captured as well as cnn.com initial post of the amazing sight.

(CNN) -- Forget Hollywood special effects or Impressionist paintings -- some of the most stunning images are created by the mysterious and often violent forces in the universe.

Witness the handful of new snapshots taken by the Hubble Space Telescope, which was equipped with a new imaging camera during a space shuttle servicing mission in May.

It's back in business and there's lots to ooh and aah over.

"Let there be no doubt, this is truly Hubble's new beginning," said Ed Weiler, NASA's associate administrator, during a news conference Wednesday.

Take the image on the left of planetary nebula NGC 6302, also known as the Bug Nebula or the Butterfly Nebula.

Its "wings" are made of gas heated to more than 36,000 degrees Fahrenheit and there is a dying star at its center.

"The gas is tearing across space at more than 600,000 miles an hour -- fast enough to travel from Earth to the moon in 24 minutes," NASA's Web site says.

The "butterfly" is more than 2 light-years across.

NASA took advantage of the special filters on Hubble's camera to isolate the light of different elements, said Bob O'Connell, chair of the science oversight committee for Wide Field Camera 3.

The red in the image is nitrogen gas, for example, and the blue is oxygen. See some of the previous amazing images taken by Hubble

Colors are also prominent in the image of globular star cluster Omega Centauri, which contains almost 10 million stars, but the color contrast here is real. The gold dots are stars like our sun, but the blue ones are extremely hot, while the red ones are cool, O'Connell said.

"Just by looking at the color of the stars in the picture, you can sort them by temperature and evolutionary state because the temperature differences here are caused by differences in the internal structure of these stars and in the kinds of fuels they're burning deep inside of them," O'Connell said.

Another image shows Stephan's Quintet, a group of five galaxies -- some of which are 290 million light-years away in the constellation Pegasus. Over time, those galaxies will eventually merge into a single big galaxy, O'Connell said.

Finally, images of a stellar nursery as seen in visible and infrared light reveal the secrets inside the Carina Nebula, located 7,500 light-years away.

"This is a cloud of dense material which is being bombarded by intense radiation from surrounding stars," O'Connell said.

"But dissolve to infrared and the cloud disappears. ... An energetic infant star is being formed inside this cloud."

Hubble is expected to continue its mission for at least five more years.
