Breast cancer screening breakthrough

Couresty of yourobserver.com

The winner of the 2012 Google science fair was announced this summer, topping very stiff competition from around the world. Brittany Wenger, of Lakewood Ranch, USA was awarded first prize for her submission, which is expected to make a big impact in breast cancer screening.

Ever since a project in elementary school which introduced her to the world of computer programming, Brittany has chosen to preoccupy herself with textbooks on the how-to’s of programming neural networks. As a result, she has developed a program which is not only able to assess a tissue sample for malignancies, but is also able to learn from previous trials and improve its efficiency at doing so. A type of artificial intelligence if you will.

Despite the fact that there are many accurate ways to detect cancer in a patient, the importance of this development lays in the fact that it can be used to analyze tissue samples from a process called fine-needle aspiration, which is one of the least invasive procedures for detecting breast cancer. Previously, the questionable accuracy of fine-needle aspiration prevented it from being a truly reliable means of screening, but now with this neural network available, it should become a confident alternative to more invasive procedures.

The slideshow presentation for her submission can be viewed here.
I recommend watching this video to hear her own explanation of the project:

She was awarded $50,000 in scholarship money, an internship with a fair sponsor and a 10-day trip to the Galapagos Islands for her submission, which can only be described as an amazing accomplishment for a 17-year-old girl. Her plans to expand this program to work with other forms of cancer and diagnoses, reducing the requirement for invasive procedures, is just one more thing we can all be thankful for as we slowly move toward old age.

MIT researchers announce a possible solution to oil spills

In 2010, a massive oil spill devastated the Gulf of Mexico, leaving much of its coast in a seemingly hopeless environmental disaster. As a result, some important questions were raised, such as what the most effective method of removing oil from the water would be. The world really demonstrated its lack of preparedness in light of this incident, as the solutions involved extremely inefficient measures, such as setting fire to the oil on the surface of the ocean. However, this incident sparked a significant interest in researching new methods which separate oil and water as a precaution against future spills.

Recently, one of the most intriguing ideas driving research has been the use of magnetic nanoparticles with an affinity for oil. As a result, researchers at MIT have recently announced their progress on a ferrous nanoparticle which first binds to oil in water and can then be drawn out of the water by way of a magnet, taking the oil out with it. Furthermore, this technique is expected to be a vast improvement on the efficiency of previous techniques used to recover oil, because once the oil has been separated from the water, the nanoparticles can be recovered, which leaves the uncontaminated oil behind for sale or usage.

The concept is there, but the question of how practical such a method will be when dealing with vast bodies of water is still uncertain. Also, the nanoparticles themselves could be seen as an environmental contaminant, so recovery of the oil and then recollection of the particles should probably be done in a controlled manner. Hopefully some resolutions to all the issues surrounding this idea come to fruition soon, because even British Columbia could stand to benefit from the security this method of cleanup might offer, in light of the recently proposed pipeline.
