Fish bones may be used to create the environmentally friendly plastic we've been hoping for

-

 


    Plastics are a blight on land and sea, posing a threat to human and animal welfare, but finding a more "green" solution, apart from dramatically cutting our takeout containers and plastic straws, has proven difficult.

    Polyurethane, a form of plastic used in clothing, spray foam, mattresses, and other products, is made from crude oil and phosgene, a poisonous gas. The Memorial University of Newfoundland in Canada has created a method for turning fish waste into a substance that is similar to polyurethane but does not contain petroleum-derived crude. This plastic, which is composed of biological materials, will then dissolve more quickly, resulting in fewer microplastics in the atmosphere.

    “Around 40 to 60 percent of a fish's landed weight ends up going to waste,” she says. She claims that “surprisingly a lot of waste fish and waste oil will be generated around the world,” with oil accounting for 20% of the total.
    
    One of the most important characteristics of bioplastics is how quickly and effectively they dissolve in the atmosphere, which can help deter the contribution of any more microplastic to the oceans, which are still clogged with debris.

  Did people live more than 100 years this  days too Okinawa, Ryukyuan, Japanese Okinawa lies on the south of Japan's mainland, where a group of islands known as "Land of immortals" which spreads over 1000km long. People who live here have the highest life spans in the world. According to studies, there are more than 450 people are there over the age of 100. Above 66% of People who reached 100 were still living independently on others.  Studies show that it is the only place where people with low rates of heart diseases, strokes, cancer, and diabetes.

  Crew climbs aboard SpaceX NASA and SpaceX will need to thread the needle to launch the SpaceX Crew-1 Sunday evening. An approaching polar front will bring increasing clouds and therefore the threat of scattered downpours to the Space Coast. The 45th Weather Squadron downgraded the launch probability of Sunday’s launch from 60% attend 50% only to upgrade it to 80% afterward . The Navy meteorologists are highlighting the cumulus rule, flight through precipitation and surface field rule because the primary concerns for a weather violation Sunday evening. Teams are monitoring conditions both at the Cape and downrange across the Atlantic on the spacecraft’s ascent path to orbit. The SpaceX launch that was alleged to happen Saturday evening was pushed back 24 hours thanks to strong onshore winds. Come Sunday evening, the Space Coast can expect highs within the low 80s, light winds out of the northeast, and a 30% chance for showers which will start to taper off by 5 p.m. The launch remains
