The new way of producing fuel(Gut fuel)..!!

E.Coli is a bacterium found in the gut of endotherms,so called the warm blooded animals.The gut microbe can replicate the molecules and produce diesel.

A recent research from the university of Exeter,developed a new method which makes use of bacteria to produce fuel,which is almost identical to conventional diesel fuel.So they used bacteria and added genes from camphor tree,blue green algae and other two bacteria namely Photorhabdus luminescents and Bacillus subtilis that allows E.Coli to make hydrocarbons from fatty acids and then fed on sugars and yeast extract and then observed them floating in the growing medium suggesting that the microbes secrets the hydrocarbons from their cells once produced.
This biofuel is a fuel derived directly from the living matter that could make cars or motorcycles running on natural gas.This research continues to wean the E.Coli off plants and use organic wastes from agriculture or even sewage.

Amputed fingertip can be healed..

Stem cell  therapy is extraordinarily promising, since our bodies use different types of tissue- specific stem cells to fit a particular purpose,nowadays scientists all over the world are researching in new ways to harness stem cells and to use them in diagnosing various diseases.
A new study of mice led by Dr.Mayumi Ito, a stem cell biologists and dermatologists at NYU's Langone medical centre discovered a new groups of stem cells in fingernails that promote the regeneration of amputed finger tips  in mice,which may also play a role in bone regeneration.
Ito and her coworkers found a class of stem cells beneath the nails.These cells reside in sensitive tissue under the bottom most part of the fingernail.This region is concealed by skin .Further more the report tells that this was due to the structural tissue around the nail producing a family of proteins called "Wnts"(wints) which helps nerve cells to produce growth promoting chemicals that renew the bone and tissue in the finger tip of mice.These reports suggest that nail stem cells and Wnt proteins are sufficient for limb regeneration.
