Rot fruit becomes bioplastic In this process special enzymes are used, which cut up the plant fibers in the waste. They convert the fibers into simple sugar molecules. Subsequently, bacteria break down the sugars into lactic acid, from which valuable bioplastic is made. Plastic waste becomes clothing Plastic can be ingeniously transformed into plastic polyester.
Last year, NASA discovered no fewer than seven earth-like planets around the Trappist-1 star. Several of them are in the habitable zone - the right distance to their star to hold life. And now an international research team has shown that six of the seven planets can contain large amounts of water.
The health authorities require that drug manufacturers provide their medicines with a best-before date, so that patients can be sure that a medicine is still working and that no toxins have been formed. Producers check the shelf life by storing a medicine in the recommended way and regularly testing its effectiveness.
Blood group system has been around for 20 million years The so-called AB0 blood group system is at least 20 million years old and was once created by a common ancestor of man and monkey. This is the conclusion of a 2012 study by an international research team including the University of Chicago, published in PNAS.
A hidden volcano world can melt more than 2 million cubic kilometers of ice in West Antarctica. Until 2017, only 47 volcanoes were known in that part of the South Pole, but thanks to a groundbreaking discovery, that number has now been increased to 138. So the ice-cold continent is one of the largest volcanic areas on earth - which worries researchers.
White shark does not get the sun in his eyes The world's largest predator fish, the white shark, hunts with the help of sunlight. According to studies from the Australian Flinders University. For a month, researchers observed 44 sharks in the sea near South Australia. It turned out that on sunny days the fish attacked their prey animals from the east in the morning, while they usually approached their victims from the west in the afternoon.
Originally, the team of scientists at the University at Buffalo wanted to study the mucin-7 protein to find out more about its effect on our health. Mucin-7 is the substance that makes your saliva slimy, and the protein would help rid the body of harmful bacteria. But during the research they came across a mysterious variant of the healing protein.

Volcanoes are a major geological threat and can cause enormous destruction worldwide. With a so-called super-eruption, 1000 gigatons of volcanic material is thrown into the air and entire continents can be covered with a layer of ash. Material will also end up in the atmosphere, as a result of which the global climate can be upset for decades.
About the lunar eclipse The earth casts a long shadow into the space, through which the moon occasionally passes. Sometimes the moon is completely covered by the darkest part of the Earth's shadow and we get a total lunar eclipse. Other times, that shadow falls only partially on the moon and so we also see a partial lunar eclipse - as now.

What does it mean if an earthquake is 7.5 on the Richter scale? What is 7.5 if you compare it with other earthquakes? And how do you actually measure this? These questions are always asked when an earthquake occurs. What is the Richter scale? The Richter scale is used all over the world to indicate how large and powerful an earthquake is.
Alien: Covenant In the film: A colonization ship with more than 2000 people on board is on its way to an exoplanet. On that planet they come across the only survivor of the Prometheus expedition: a mission to investigate where life on earth originated.

An inverted rainbow hot zenith arch. The weather phenomenon is somewhere else in the sky than a normal rainbow, and is created in a different way. Ice crystals break the light You can see the zenith arch when the sunlight is broken through ice crystals in thin cirrus clouds high in the atmosphere.
Thousands of asteroids have a job that brings them fairly close to the earth. Once a year, a planet the size of a car comes close to the earth, resulting in a meteor whizzing through the air until it burns out. 19-meter-large asteroid above Russia A larger asteroid can break if it encounters the atmosphere, so that only the remains fall to earth.
