THE RIPPLING SURFACE OF A SINGLE LAYER OF MOLECULES
"The layer is actually comprised of two different molecules that tend to separate something like oil and water, and in this image we’ve captured what that separation looks like at a very early stage," said Seth B. Darling (Argonne National Laboratory), who collaborated with Steven J. Sibener (University of Chicago) on the photograph.
Each of the millions of molecules in the image has sulfur at its head, but one type has carbon and hydrogen at the tail whereas the other has carbon and fluorine. The heights of the two molecule types differ by about 0.2 nanometers.
The image was featured on the cover of Science, February 18 2010.

Sixteen-year-old Elif Bilgin of Turkey has developed a way to replace traditional petroleum-based plastic with banana peels.
The Turkish teen took home a US$50,000 prize for her project “Go Bananas!” Thursday after winning the second annual Scientific American Science in Action Award, associated with Google Science Fair.
“My project makes it possible to use banana peels, a waste material which is thrown away almost every day, in the electrical insulation of cables,” Bilgin said in a media statement.
“This is both an extremely nature-friendly and cheap process, which has the potential to decrease the amount of pollution created due to the use of plastics, which contain petroleum derivatives.”
Bilgin spent two years developing the bio-plastic, which does not decay. She said the process is so easy that it is possible to repeat at home, with special care taken for chemicals used in the production process.
In September, the teen will compete at Google’s California headquarters for the overall Google Science Fair prize for 15-to-16 year olds. She will also have access to a one-year mentorship.

Bald Eagle gets a new 3D-Printed Beak
“Sometime in 2005, Beauty the bald eagle was shot in the face by a poacher, which damaged her beak badly enough that she couldn’t eat on her own. Animal rescue workers found her before she starved to death, and volunteers at the nonprofit group Birds of Prey Northwest nursed her back to health via tube-feeding and, later, hand-feeding with forceps. But it became increasingly clear that her beak was never going to grow back — meaning that Beauty would never be able to feed herself. She was on track to be euthanized.”
“But raptor specialist Jane Fink Cantwell, who dresses like Indiana Jones, refused to take “dead bald eagle” for an answer. She joined forces with mechanical engineer Nate Calvin of Kinetic Engineering Group, and together with other scientists, engineers, and even a dentist, they designed a nylon polymer beak that would perfectly replace Beauty’s lost upper mandible.
Calvin developed the new beak using a 3-D modeling program, then used a 3-D printer to fabricate it. After an arduous procedure to attach her prosthetic, Beauty was able to eat, drink, and preen herself on her own.”

Window Socket - Kyuho Song & Boa Oh
So this is an absolutley brilliant idea! Just attach the plug on to a window and it will harness solar energy. A small converter will convert it into electricity which can be freely used as a plug when you are in the car, on a plane or outside.
Love this design and I really think it has a great potential.
First Algae-Powered Building Goes Up in Hamburg
A 15-unit apartment building has been constructed in the German city of Hamburg that has 129 algae filled louvered tanks hanging over the exterior of the south-east and south-west sides of the building—making it the first in the world to be powered exclusively by algae. Designed by Arup, SSC Strategic Science Consultants and Splitterwerk Architects, and named the Bio Intelligent Quotient (BIQ) House, the building demonstrates the ability to use algae as a way to heat and cool large buildings. (x)
You guys this is so cool: this building has the potential to be completely energy-independent, with the algae growing during the day and serving as power source, shade & cooling, UV protection, and a sound buffer. The outside of the building will also look really cool as the algae grow, and the panels change color and shift toward sunlight throughout the day.
The algae will essentially serve as a bioreactor, generating biomass which is processed into ‘biofuel’ which will then power the building’s activities (heating, electricity, etc.) throughout the day:The building is set to open later this month, and many researchers and engineers are eager to see if this idea can be practically applied to other buildings around the world.The algae flourish and multiply in a regular cycle until they can be harvested. They are then separated from the rest of the algae and transferred as a thick pulp to the technical room of the BIQ. The little plants are then fermented in an external biogas plant, so that they can be used again to generate biogas. Algae are particularly well suited for this, as they produce up to five times as much biomass per hectare as terrestrial plants and contain many oils that can be used for energy. (x)
Potentially, the concept could power whole buildings at very low running-costs and act as a CO2 sink.

How Fracking Causes Earthquakes
Contributing Mother Jones writer Michael Behar “has an intriguing feature today that details the science behind the link between injection wells and earthquakes.”
From the New York Times:
VANCOUVER, British Columbia — Our digital age is all about bits, those precise ones and zeros that are the stuff of modern computer code.
But a powerful new type of computer that is about to be commercially deployed by a major American military contractor is taking computing into the strange, subatomic realm of quantum mechanics. In that infinitesimal neighborhood, common sense logic no longer seems to apply. A one can be a one, or it can be a one and a zero and everything in between — all at the same time.
It sounds preposterous, particularly to those familiar with the yes/no world of conventional computing. But academic researchers and scientists at companies like Microsoft, I.B.M. and Hewlett-Packard have been working to develop quantum computers.
Now, Lockheed Martin — which bought an early version of such a computer from the Canadian company D-Wave Systems two years ago — is confident enough in the technology to upgrade it to commercial scale, becoming the first company to use quantum computing as part of its business.
This is the type of thing that I’d ideally be designing in the future.
Neurons growing in a cell culture
These time lapse animations use phase contrast microscopy to show neural stem cells in a nutrient medium for 4 hours. They reveal the dynamic growth and recycling of dendrites and synapses as neurons establish relationships with each other. The social behavior of these cells creates the incredible properties of the mind and brain.
