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. PETas e works by reversing the manufacturing process by reducing polyesters  back to their building blocks ...

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...

Meet the creature that can pretty much regenerate everything in it's body. Axolotl,  a Mexican salamander which is familiarly known as " walking fish " but it's not a fish it's an amphibian.This creature can regenerate the same limb for more than one hundred times. This specie can be found in Lake Xochimilco. Lake Xochimilco In the wild it remains in the larva state   and will never undergoes Metamorphosis into an adult salamander. According to International Union for the Conservation of Nature and Natural Resources [IUCN] these species are critically endangered.The key thing for it's regenerative ability is it's immune system.   Immune cells called  Macrophages are critical during the early stage of regenerating it's lost limbs. Taking out of these cells,permanently stopped it's regeneration ability.In fact, Macrophages Scientists done an experiment by injecting a drug which takes off the Macrophages completely, they observed no r...

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.                          ...

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 ...

No credit cards, debit cards, cheques ,vouchers ,cryptocurrencies. Just smile into the camera and your payment is done Interesting isn't it,  this is the  technology from Face++.Already this has been used in many popular apps.In China now it is possible to transfer money through Alipay a new revolutionary mobile payments app used by more than 120 million people in China.This uses only your face as  credentials.This system seems to work quite simple.Once a picture is uploaded into the system, payments confirmations,Identity verifications goes immediately in place by itself. This can also detect gender,differentiate face,eye status and much moreApart from that new payments app Didi, one of the most authoritative ride-hailing company of China uses the Face ++ software to let passengers confirm that the person behind the vehicle is a  legitimate and licensed d river. .. Face  payments can improve the financial security of the user.   This Face++ software is al...

Scientists have developed a new drug to prevent migraine :                                          Erenumab is an injectable drug that blocks pain signals in the brain.The drug, called   Erenumab consists of human antibodies. It   works by targeting a receptor in the brain where a protein associated with migraines usually blinds. This protein transmits migraine pain signals during an attack. Erenumab blocks this receptor. thus preventing a migraine attack. the drug reduced the number of monthly migraine attacks by more than 50%.   No side   effects of this drug were recorded in human patients. Migraine is a neurological disorder characterized by a severe throbbing pain on one or both sides of the head. In some cases, head pain may be accompained by other symptoms including Naused, vomiting, numbness or tingling in the face. Patients may be also experience sensi...
