GREEN PETROL-say gud bye to petrol crisis
Scientists at University of Massachusetts-Amherst in the US have announced the creation of petrol from plant matter, with almost no carbon footprint. The “green petrol” – as the researchers describe it – is identical to standard petrol, yet created from sustainable biomass sources like switchgrass.It may take five to 10 years for the green petrol to arrive at the pump or find its way into a fighter jet, his team’s work has bypassed significant hurdles to bringing green petrol biofuels to market. It is likely that the future consumer will not even know that they are putting biofuels into their car. Biofuels in the future will most likely be similar in chemical composition to petrol an

FUSION HC6-the ultimate experience
This invention is the ultimate innovation for gym and entertainment enthusiasts. Once you appreciate its looks and design, you begin to realise how much you actually want to own one of these, despite it being out of many peoples price range for this kind of equipment. Nevertheless let's have a closer look at this ultimate fitness invention. The Fusion HC6 is one of the most sophisticated home gyms available and accommodates a vast array of exercises into a single contraption. The amazing thing about this gym is the ability to attach an add-on. The add-on is a built-in full-blown media centre. The fitness machine and media inbuilt makes this one of the most appealing gyms on the world.

CULTIVATING DIESEL-JATROPHA SHRUBS
Jatropha is a valuable multi-purpose crop to alleviate soil degradation, desertification and deforestation, which can be used for bio-energy to replace petro-diesel, for soap production and climatic protection, and hence deserves specific attention .
USES OF JATROPHA:
a)Currently the oil from Jatropha curcas seeds is used for making biodiesel fuel in Philippines.
b)Biodiesel produced from jatropha is one of the most promising solutions for tackling the growing carbon emissions from transport.
c)Jatropha podagrica or buddha belly plant or bottleplant shrub was used to tan leather and produce a red dye in Mexico and the Southwestern United States. It is also used as a house plant.
d)Jatropha cuneata limberbush, whose stems are used for basketmaking by the Seri people in Sonora.
e)Jatropha curcas, also known as physic nut, is used to produce the non-edible Jatropha oil, for making candles and soap, and as a feedstock for producing bio-diesel.
NEW QUASAR-California-Santa Cruz astronomers rockzz
Quasars are enormously bright cores of very distant galaxies thought to contain “super-massive” black holes a billion times larger than our sun. They are seen only in the centers of very distant galaxies that formed long ago .University of California-Santa Cruz astronomers are the first to discover the onset of a huge flow of gas from a quasar, or the super-bright core of an extremely remote young galaxy still being formed. The gas was expelled from the quasar and its enormous black hole sometime in the space of four years around 10 billion years ago – an extremely brief and ancient blip noticed only by a sharp-eyed undergraduate and the unlikely convergence of two separate observational efforts.

Bagalight Table Lamp
This is one of those gadgets that I kind of wish they were kidding, sadly, they aren’t. If anyone were to see this on your table, they’d likely think you had a small child that made an attempt at some arts and crafts one afternoon. Although despite the fact that it does look a bit ugly, it is said to be an eco-friendly table light. Actually the people at Liquidesign wanted to come up with an eco-friendly light and that’s how they came up with the idea for this lamp.
The bag is part of an entire series of lighting. Within that series is a pendant light as well, that is made from card and paper, as is the lamp shown here. You can also pick up their desk lamp version of the light. Hopefully the desk lamp version does actually point light directly at your desk. It’s always nice to have eco-friendly lighting. However, it being eco-friendly doesn’t exactly give the designers a free pass to stop caring about the look of the overall design. You can purchase this Bagalight for £29.99 or about $43

BLOGGER PLANT-"midori-san" the first green blogger
A potted plant named "midori-san" is proved to b the first green blogger.This succulent "sweet heart plant" contains bio-electrical sensors that translates the signal given by the plant into japanese language script using an efficient computer algorithm.
So far, the plant’s highly structured posts summarize the day’s weather, temperature and lighting conditions, describe its overall physical condition, tell how much light it received via the user-activated lamp (see below), and explain how much fun the day was.
The recent post by this green blogger is as follows:
"Today was a sunny day and I was able to sunbathe a lot. I had quite a bit of fun today."
"It was cloudy today. It was a cold day."

CAMERA PILLS*****SAY GUDBYE TO SURGERY*****
A swallowable camera, little bigger than a normal pill, can snap pictures as it floats through the stomach and intestine, offering a less invasive way to perform diagnosis than an endoscope or surgery.The pills are used on patients who typically have internal bleeding or abdominal pain that is hard to diagnose. Up until now doctors have used an endoscope – a camera on a flexible tube – to examine such problems. However much of the small intestine, which is tightly coiled and stretches for up to 6 meters, could not be reached using this method and the only alternative was for patients to swallow barium and have an X-ray which produced poor quality images.Now the camera pill allows the doctors a near perfect view of the inside of this organ as it makes its way through a patient's body. WORKING:
The pill is similar to a digital camera and sends 50,000 still images from along its journey to a small recorder device worn on the patient's belt. After eight hours the doctors take the recorder and download it onto a computer before watching the footage to see if there are any signs of bleeding, disease or swelling. If a concerning area is found then dedicated treatment can be taken to combat the problem.
Patients having the pill, which cost less than £400 each, must fast the day before but can leave the hospital and go to work as normal while the pill is in their body. The whole process takes just a day and patients will generally be given the results within a few days.
PATIENTS EXPERIENCE:
One patient to benefit was BRITNEY , 28, of Texas, who has suffered from severe abdominal pain for three years. For most of that time doctors were unable to diagnose what was the cause was, and it was only through the use of the camera pill that a firm diagnosis was possible. When the pain first started it would last a couple of days and was bearable but by the end it was really bad and I was doubled over in agony unable to do anything. It was very frustrating that no one was able to diagnose what the problem was.
I was referred to Dr John last year and when he suggested the camera pill I thought it sounded strange but just said 'let's do it'. It is quite a big pill but ok to swallow and I didn't feel anything as it passed through me. One of the nurses allowed me to watch the live images which was quite amusing.A few days later Dr John said the footage proved without doubt that I had Crohn's Disease which is like an inflamed gut. It was such a relief to finally have a diagnosis. It is a very cool piece of equipment. I've had nearly every test available but this was the best and also the least invasive. Also because it showed exactly where it was in my intestine they were able to decide which medication was most suitable. I still have a lot of pain but at least we know what we are dealing with now and the steps to control it.
