Scientists have created an enzyme that eats plastic



The world's oceans are filled with plastics more than 5 million pieces of it are floating around being eaten by aquatic animals. Every year more than 100,000 marine animals and seabirds are killed by plastic waste.The accidental discovery of this natural enzyme was made while examining the structure of a bacterium found in the waste dump in Japan.A crew of Japanese researchers described that this bacteria named as Ideonella Sakaiensis could break the molecular bonds of one of the world's most used plastics Polyethylene terephthalate.
The aim of the researchers was to determine how this works and what's the structure of it, but they ended up creating an artificial one better than the natural one.Ideonella Sakaiensis was found outside of a bottle recycling plant, the pathogen appears to have evolved a pair of enzymes.It uses these break down a PET.PETase works by reversing the manufacturing process by reducing polyesters back to their building blocks.Ideonella Sakaiensis can degrade PET in 96 hours you can see it clearly via electron microscope that the PET being degraded.This natural enzyme could result in recycling millions of tonnes of plastic, especially plastic bottles.It is estimated that the world produces over 300 million tonnes of plastic every year.Currently, we are buying 10,00,000 (1 million) plastic bottles per minute world widely and we recycle only 15% of that.

Artificial Neurons can replace some real ones in our brain

Researchers have created the world's first Artificial Neuron which can parody the function of Organic Neuron.This could even replace some of the real neurons in our brain. Artificial neurons are made of conductive polymers.Neurons store and transmit information in the brain.These are as small as fingertip and contain no living parts.Miniaturizing the neuron size would enable it's implantation into the human body.   This is a potential way to end neurological disorders like spinal cord injuries and Parkinson's disease."Our artificial neuron is made of conductive polymers and it functions like a human neuron"   said Agneta Ritcher-Dahlfors a lead researcher from the Karolinska Institute in Sweden.Neurons communicate in our brain through chemical signals.The first thing that Artificial neuron does is it detects chemical signals which are then transmitted electrically from one neuron to another.Then the electrical signals release chemical neu...

BIRDS can see EARTH's MAGNETIC FIELD

A protein in the eyes of birds is what gives them their internal compass allows them to navigate using  the Earth's magnetic field . Birds can sense Earth's magnetic field which allows them to navigate and Embark on migrations that span tens of thousands of kilometers . Researchers thought Iron rich cells in birds'' beaks acted as microscopic compasses.But new studies have found increasing evidence that certain proteins in birds eyes .Might be what allows them to see magnetic fields.The studies examined 39 zebra finches European robins .Both single out a protein called Cry4 (cryptochromes) , a light sensitive protein found in the retina.The team found that while levels of Cry1 and Cry2 rose and fell over the day. Cry4 levels remained constant indicating the protein was being produced steadily .This is the first that such a molecule has been identified in animals A specific molecule that is responsible for the detection of magnetic fields. Cry4 is a ...

Autonomous Car

Have ever heard about driverless car. It means that there would be no person to drive the car,Which be done in some years. Driveless is also known as autonomous car, which can automaticallySense the environment and can senses the environment and navigates the car without human                                                                                   It also have some gadgets like  GPS,radar,ex.... to detect the surroundings and also have sensors which can detect speedbreakers,stones, Obstacles.These cars contain a analyzing sensory data distinguish cars on the road,it has significant reduction in traffic collisions Which result injuries. Driveless cars include less insurance.                          ...
