Best Science Pictures of 2010 :)

Best Science Pictures of 2010 :)




A microscope-enabled closeup of hairs on the seed of the common tomato won an honorable mention in the photography category.

The hairs secrete a mucus that appears as a clear membrane at the edge of the seed, according to photographer Robert Rock Belliveau, a retired pathologist. This mucus has several purposes: killing predators with a natural insecticide, preventing the seed from drying out, and anchoring the seed to the soil.
Plant-Gene Map



What looks like a fireworks display is really a portion of AraNet, a gene map of the mustard plant Arabidopsis thaliana, which earned an honorable mention in the illustrations category. (Get a genetics overview.)

A Carnegie Institution for Science team built Aranet from more than 50 million experimental observations of the plant and other organisms. Genes involved in the same biological processes are linked by lines, and color shows the strength of the link.
Rough Waters



Snagging first place for photography, this micrograph—a photograph taken through a microscope—shows 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, who collaborated with Steven J. Sibener from Argonne National Laboratory 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 is featured on the cover of the February 18 edition of Science.
“Horror” Virus



In a 3-D image, a bacteriophage aggressively attacks a bacterium “B-movie horror style,” according to creator Jonathan Heras of Equinox Graphics, Ltd. The digital ambush snagged an honorable mention in the illustrations category of the 2010 International Science and Engineering Visualization Challenge.

Bacteriophages are viruses with “alien, spindly legs” and sucker-shaped mouths used to “relentlessly pursue their prey,” Heras said in a statement. The viruses hijack bacteria’s biology and use the victims as virus “replication factories,” he said. (See “‘Zombie Virus’ Possible via Rabies-Flu Hybrid?”)

Overall, the 2010 entries were “exceptional,” communicating science “in a way that the public can understand and appreciate,” Monica M. Bradford, Science’s executive editor, said in a statement.

“The international competition highlights the innovation and technical expertise of scientists who are able to visually attract a wide audience and engage them to experience the complex nature and beauty of science.”
HIV in 3-D



The most detailed 3-D model yet of the HIV virus won first place for illustrations in the 2010 International Science and Engineering Visualization Challenge.

Sponsored jointly by the journal Science and the National Science Foundation, the annual competition awards entries that “engage people worldwide and convey science close up in novel and visually stimulating ways,” according to a statement. Judging criteria include visual impact, effective communication, freshness, and originality. (See some of the 2009 winners.)

A Russian team led by Ivan Konstantinov analyzed data from more than a hundred scientific journals to digitally depict HIV as close to the real thing as possible. The two-tone color scheme shows HIV (orange) attacking and fusing with an immune cell (gray). The triangular cut-away shows how the virus integrates itself to turn the cell into a virus factory.
Fungus Poster



All manner of fungi sprout in a detail from an educational poster that won first place in the Informational Graphics category. Depicted species include those found in cheese, beer, bread, and even hibernating bats.

“Fungi is a very complex subject,” Kandis Elliot, senior artist in the Department of Botany at the University of Wisconsin, Madison, said in a statement. “It’s not just about mushrooms anymore.”
Centipede Robot



A photograph of a centipede-inspired robot won an honorable mention in the photography category. The bug-size robot’s design may inspire better models for movement, according to Harvard University experts.

The multisegment millirobot offers insight into how flexibility and body undulations can enhance movement, and whether there is an ideal number of legs for efficient and stable walking. (See “Robot Fish to Detect Ocean Pollution.”)
 

Top 10 Fuel Efficient Cars


These days fuel efficient cars are in great demand. Car manufacturers are therefore competing with each other to give car buyers a choice in terms of other features along with fuel efficiency. Today you will get many cars that are not only fuel efficient but are also comfortable, safe and are fun to drive. Still when car buyers plan to buy a car that is popular for its fuel efficiency they also look for added features as well. Here in this article a brief sketch is given about the top 10 cars that are sought after for fuel efficiency as well as their extra features.
1. Audi A4



The first on the list is the Audi A4 which according to EPA returns fantastic mileage per gallon (MPG) both in city and highway driving conditions. One can get 23 MPG in the city and 30 MPG on the highway from the Audi A4. This car has a four-cylinder engine under the bonnet and is powered by turbocharger. Another added feature is that it has got direct fuel injection system. You can derive 258 lb-ft of torque from this car and the acceleration is great even while returning good fuel economy figures. It is also available as a station wagon variant. If you go for looks and would like to enjoy your drive then Audi a4 is the car you should go for.
2. BMW 335d



The BMW 335d which is next on the list returns 23 and 36 MPG in the city and highway respectively. Apart from its fuel economy you will love its power and torque. Rev up the engine and it will develop 425 lb-ft which is much more than many other cars in its class. Acceleration is also fast without compromising on fuel economy. The BMW 335d by far is the best car in the diesel segment that is currently being sold in USA.

3. Chevrolet Volt



Though the fuel efficiency figures of the Chevrolet Volt are yet to be declared by EPA yet it sounds promising given the fact that this car runs on twin power mode (electric motor and gasoline). That’s right; you don’t have to use fuel at least up to 40 miles. Thereafter you can switch over to gas. This can be an ideal car for people who have to commute short distances everyday. Now they don’t have to fill gas as they used to earlier.
4. Ford Fiesta



The Ford Fiesta which is available in both automatic and manual transmission variants returns fantastic figures (29 MPG for city and 40 for highway) though the automatic one returns a bit higher. The three great things about the Ford Fiesta are its size, price and fuel efficiency. The car looks good too and takes on the curves smoothly. You will love to drive this car for your everyday errands.
5. Ford Fusion Hybrid



Returning 41 and 36 MPG in the city and the highway respectively the Ford Fusion Hybrid is perhaps one of the most popular hybrid cars. It offers high mileage that can be expected from a hybrid and at the same time it gives the pleasure of a mid-size sedan. The car is spacious and good to drive. The dashboard is user-friendly and the other gizmos give that technological aura. If you are looking for a car that has everything packaged into one then it should be Ford Fusion Hybrid.
6. Honda Civic GX



The Honda Civic GX returns 24 and 34 MPG in city and highway respectively. This car really saves on fuel because it burns CNG (compressed natural gas). CNG as you know beats gasoline in terms of price, availability and safety. The Honda Civic GX has a simple system that burns GNG cleanly. Though it cannot beat gasoline powered cars in terms of range coverage yet this car offers a healthy range. If you are concerned about the environment and cutting down on gasoline costs then this car suits you.
7. Honda Fit



The Honda Fit which is available in three variants (2 automatic and 1 manual) returns an average of 28 and 35 MPG in city and highway respectively. Honda Fit which falls in the sub-compact category is a versatile car. The car can carry a lot of baggage and other stuff and entry and exit is quite hassle-free. Moreover given its fuel economy it is really an incredible car.
8. Hyundai Accent



The Hyundai Accent returns fuel averages of 27 and 36 MPG (city/ highway).

The car used to be lacking in the safety department earlier but its manufacturer stemmed out the problems last year transforming it into an affordable and fuel efficient car. It’s not big either and since it’s responsive you will enjoy driving it. The two big plus points are its mileage and price.
9. Volkswagen GTI



The Volkswagen GTI is a hatchback with front wheel drive which returns 24 and 32 MPG in city and highway driving conditions. Its fuel economy is really good and even better than many cars. Its engine is similar to that of the Audi A4. The only difference is the power as the Volkswagen GTI is a slightly toned down version. The car delivers 200 hp without guzzling on gas. That’s great news for car enthusiasts.
10. Volkswagen Jetta/Golf TDI



The Volkswagen Jetta and Golf TDI are available in two variants (automatic and manual) and returns great fuel averages. It gives 30 and 42 MPG, in city and highway driving conditions respectively. Both the cars are available in sedan and hatchback versions and sport a turbo diesel-powered engine. If you want to experience what modern technology can do to diesel cars then you should test drive these two cars. It is not that you have to cut down on acceleration to achieve great fuel averages with the Jetta because it just needs a judicious push on it. The 2011 model has been redone by Volkswagen to give you fuel averages that will make you grin in satisfaction. The interior is modest with nothing outlandish but the fuel economy of this car is sure to attract a lot of car buyers.



So, take your pick from these world cars which are currently vying with each other to take the honours in terms of fuel efficiency. 
 

Walk along the cableway!


Walk along the cableway!! But @ What Height???


Freddy Nock, acrobat, daredevil, walked a tightrope cable car.
45-year-old circus performer did this trick on the cable car Corvatsch in Switzerland. 



IF you start to wobble, just don’t look down.
 
  
 
 
 


Due to bad weather the first attempt failed, the second was successful.

Starting at the station at an altitude of 10,836 feet …
He dotopal to an intermediate station at an altitude of 8,865 feet.
This is not new for him, he did a similar trick in German mountain.

In general, Freddy Nock (Freddy Nock) deals with acrobat 4 years and as you can see he is pretty good at it…
