Heart tissue sustains irreparable damage in the wake of a heart attack but because cells in the heart cannot multiply and the cardiac muscle contains few stem cells, the tissue is unable to repair itself — it becomes fibrotic and cannot contract properly.
The search is on for innovative methods to restore heart function and so scientists have been exploring cardiac "patches" that could be transplanted into the body to replace damaged heart tissue.
An “intelligent knife”, dubbed the iKnife (naturally) can tell surgeons whether the tissue they are cutting is cancerous or not.
In operating room situations, the iKnife diagnosed tissue samples from 91 patients with 100 percent accuracy, saving about 30 minutes of time that would usually be needed for laboratory tests.
A saying in the Old West was that God made men, but Sam Colt made them equal.
Well, not completely equal, but his invention of the revolver certainly made life better for flintlock pistol owners. Speed and accuracy were still a subjective issue.
Now, maybe even accuracy is going to be egalitarian.
When I was a young man at Duquesne, we had a rifle team. In the NCAA then, if you were going to have a popular Division I sport that offered scholarships (such as basketball) you had to offer multiple smaller (less popular) Division I sports also - with scholarships, though obviously not full ones.
A group at the Bristol Robotics Laboratory have developed a novel way of charging mobile phones - using urine as the power source to generate electricity.
Lead author Dr. Ioannis Ieropoulos from
the University of the West of England
is an expert at harnessing power from unusual sources using microbial fuel cells and says, “We are very excited as this is a world first, no-one has harnessed power from urine to do this so it's an exciting discovery. Using the ultimate waste product as a source of power to produce electricity is about as eco as it gets.”
Basically, the microbial fuel cells contain bacteria that produce electricity from pee. Bet you never thought of that, Muad'Dib.
If you have ever used a GPS system to find a route to somewhere, you might have wondered on occasion how they can be so wrong - though it's often not the signal itself that is wrong.
Yet sometimes a distorted signal can be a good thing. By figuring out how messed up GPS satellite signals get when bouncing around in a storm, researchers have found a way to do something completely outside their original intent: measure and map the wind speeds of hurricanes.
My short paper, "An Ecological Development Abstraction for Artificial Intelligence," will be featured in the symposium "How Should Intelligence be Abstracted in AI Research: MDPs, Symbolic Representations, Artificial Neural Networks, or _____?
" and will be published in the AAAI (Association for the Advancement of Artificial Intelligence) technical report for the AAAI 2013 Fall Symposium Series
. The symposia will occur November 15-17 in Arlington, Virginia.This is the abstract:
A biologically inspired AI abstraction based on phylogenetic and ontogenetic development is proposed.
MicroAire has entered the Biologics market with the launch of the StromaCell mechanical cell-separation device, which is is designed to prepare an autologous nucleated cell concentrate from a sample of adipose tissue, or fat, at the patient's point of care.
The StromaCell's closed-system design uses centrifugation to concentrate a stromal-vascular fraction from adipose tissue, for which there are numerous applications.
Antonio Stradivari is universally recognized as the most famous violin maker in the world - if people can name one violin, it is his. During his life, he and his apprentices built more than a thousand violins, violas, cellos and other stringed instruments. The importance of Stradivari's work obviously lies in the craftsmanship, the quality of the materials used and the finishes on the instruments' surfaces. The sound of a violin is a result of the combination of the materials used e.g. wood species and varnishes, the construction technique and the skill of the maker.
So scientists have sought to duplicate that sound by reverse-engineering ways it could have been done.
The 400-mile IndyCar race July 7th at Pocono Raceway will be the first open-wheeled event at the 2.5-mile, triangular-shaped track since 1989.
Pocono Raceway's triangular design, known as "The Tricky Triangle," makes it truly unique. Pocono is the America's only professional race circuit with three turns, three different radii and three variant degrees of banking.
The Solar Impulse airplane, brain-child airplane of Bertrand Piccard and André Borschberg (who co-piloted the entire journey) that can fly day and night without fuel or polluting emissions, has ended its cross-country journey in New York City. Solar Impulse is an unique adventure that seeks to put some emotion into solar power and also a flying laboratory to find innovative technological solutions for today’s solar challenges.
