Nature’s Cleanup Crew For Forever Chemicals

[ad_1]

Aligning manufacturing with nature is a massively important step toward becoming sustainable stewards of Spaceship Earth. In part, it will require addressing the existing consequences of industry and confronting pollution in partnership with nature.

Since the age of advanced chemistry in consumer products that took off in the middle of last century, the things humans make are more useful, durable, and affordable than ever. But that means they are often made of plastics and chemicals that extend more thoroughly throughout our ecosystems and stay there for much longer, even forever. Science is still working to understand the extent of pollution to Earth’s waterways, soil, even our own bodies.

Among the most concerning pollutants are polyfluoroalkyl substances, or PFAs, the ‘forever chemicals’ used to manufacture nonstick cookware, waterproof clothing, and countless other applications since manufacturers started using them in the 1930s. These days, they are being discovered all over the place, including the bloodstreams of almost every human being. Thankfully the PFA levels detected in humans have gradually declined as awareness has increased, but their presence in groundwater and food remain a real risk.

But where life is being harmed by such chemicals, life may also offer the solution: the endless creativity of microbes.

Within their tiny, often single-celled bodies, they contain the tools for creating and breaking apart endless varieties of chemicals. We harness these abilities to create things like citric acid to enhance our food, or ethanol for fuel. Microbes are even behind many of the vitamins we take to stay healthy, and countless other important chemicals.

Humans have been replicating microbes for millennia, in the form of fermentation, encouraging Lactobacillus bacteria to create lactic acid in a crock of sauerkraut, Saccharomyces cerevisiae yeast to create alcohol in a vat of beer. Fermentation is vast, but recent advances in parsing the DNA of different microbes given humans the ability to access and apply previously unknown or undetectable microbial abilities.

For instance, among the most exciting to emerge recently is the discovery of bacteria that consume PFAs as food, currently being advanced by a company called Allonnia. Their recently announced 1,4 D-Stroy system uses a specially identified bacteria that targets the forever chemical 1,4 Dioxane. Common to detergents and other consumer chemical products, been used since the 1950s, has been discovered in as much as 25% of drinking water, and causes serious health problems. To address the problem, Allonnia brings a tank of the specially cultivated bacteria to a target site, introducing them to the 1,4 D contaminated water, where the bacteria eagerly break the bonds of the forever chemical, leaving water and CO2. The company claims rates of as high as 98 percent removal of the contaminant.

This is an example of what is often called ‘bioremediation’, which essentially means using biology to clean up contamination and pollution. It’s a promising industry that has actually been around in a somewhat less sophisticated form for decades. What makes this moment different than before is the tools available to discover the useful abilities of microorganisms. This is made possible thanks to high resolution, high volume sequencing of DNA, and analytical tools that allow scientists to isolate a single microbe with a unique and super useful skill — like eating PFAs, for example. Companies and researchers are just beginning to explore the vast, untapped diversity of life already out there doing things that could help solve some of the biggest impacts of manufacturing and chemical industries.

Nature has already invented many of the solutions we are looking for. As our ability to scan swathes of DNA for specific traits and abilities becomes more refined, it will be like nature beginning to open all its patents for humanity to use.

Watch: Rare Comet Spotted Whizzing Across Dubai Sky

A comet that is passing by the Earth for the first time in 50,000 years has been photographed by the Dubai Astronomy group. The once in a lifetime Comet C/2022 E3 (ZTF) was captured at Al Thuraya Astronomy Center on January 20.

Captured between 4am and 6am, the dust tail and ionic tail are clearly seen in the images captured by the astronomy group.

The group also captured a video of the comet’s movement across the sky:

UAE residents will get an opportunity to see the comet in the next few weeks. It is expected to pass closest to Earth on February 1, 2023, at a distance of around 26 million miles. It will be equally visible till the 5th of Feb.

According to the CEO of Dubai Astronomy Group Hasan Al Hariri, although comet brightness can be difficult to predict, the celestial body can be easily spotted using binoculars and small telescopes around January and early February.

Viewing

Dubai Astronomy Group will host a special ticketed event on February 4, 2023, at the Al Qudra desert in Dubai from 6.30pm to 9.30pm that will spot deep sky objects like the comet, moon, Mars and Jupiter among others. The trip will also include astrophotography sessions, sky mapping and more.

Dubai residents can also spot the comet from their homes or open grounds using special equipment.“The best tools to observe the comet are binoculars,” said Hasan Al Hariri.“It has a wide-angle field of view of the sky so hunting down the comet becomes much easier than using a telescope because that has a narrow-angle field of view which makes it harder to locate the comet.”

The comet

Comets are icy bodies of frozen gases, rocks, and dust left over from the formation of the solar system about 4.6 billion years ago. But when they approach the sun and heat up, they become powerful cosmic objects, spewing gases and dust in a way that forms their iconic shape: a glowing core and flame-like tail that can stretch on for millions of miles.

Comets are named according to how and when they were originally observed. This particular comet’s name encodes such information:

● The letter C means the comet is not periodic (it will only pass through the Solar System once or may take more than 200 years to orbit the Sun);

● 2022 E3 indicates that the comet was spotted in early March 2022 and was the 3rd such object discovered in the same period;

● ZTF means the discovery was made using telescopes of the Zwicky Transient Facility.

Meteor Shower 2022: Geminids Meteor Shower 2022: Internet lights up with Night Sky Glitters, see video

[ad_1]

The Geminids meteor shower, which peaks around mid-December each year, is widely recognised as one of the best and most constant annual meteor showers. According to NASA, it is a unique astronomical phenomena that may be enjoyed during the night and predawn hours.

The Geminids Meteor Shower, expected to generate 120 meteors per hour and be active from November 19 to December 24, 2022, will peak on December 14th.

Many individuals shared photographs and videos of celestial occurrences on social media. People from throughout the world uploaded pictures and films of streaks of light seen in the night sky, enthralling the stargazers. Here are some of the greatest Geminids meteor shower photographs obtained by Twitter users.

What exactly is the Geminid Meteor Shower?

Geminids, according to NASA, move at 78,000 mph. These meteors are 1000 times quicker than a cheetah, 250 times faster than the world’s fastest automobile, and 40 times faster than a speeding bullet. The meteor shower was seen from both Hyderabad and Delhi.

Our solar system is still littered with debris, and the Geminids meteor shower is made up of fragments of rock comets that pass close to Earth once a year. The Geminids are made up of debris from the asteroid 3200 Phaethon.

The name “Geminids” refers to stars that appear to radiate from the constellation Gemini. According to Earthsky, the meteor shower will be best visible in the northern hemisphere, although individuals in the southern hemisphere will also be able to view some of the meteors. Astronomers predict that at the peak of the meteor showers, around 150 Geminids will be seen per hour.

The Geminids get their name from the constellation Gemini, which looks to be their ancestor. While some scientists think it is an asteroid due to its orbit and similarities to the main-belt asteroid Pallas, others believe it is an extinct comet based on studies that show a little amount of debris exiting Phaethon’s surface, as detailed in a statement by NASA.

FAQ

When were Geminids discovered?

1983 was the time when Germinids were discovered.

Which time of the year Germinids are seen?

Geminids are mostly seen in the November – December of the year.
