Scientists say they have built a cell from scratch for the first time

Scientists have discovered new multicellular life forms which emerge from the cells of a dead organism and stay in a "third state" which is beyond the states of life and death.&nbsp;

Generally, death is considered as the opposite state of life in an organism. However, procedures like organ donation emphasise how organs, tissues and cells continue functioning after the demise of the organism.&nbsp;

Scientists in the past few years have demonstrated how the cells of organisms can be used in biological robots which represent the advancements in the field of synthetic biology.

<h2>What is the 'third state' of organisms?</h2>

In a new study, published in the journal&nbsp;Physiology, researchers have discussed the possibility of using cells from organisms, either dead or alive and using them in machines with totally new functions.&nbsp;

This underlines a biological "third state" which is not part of the general categories of life and death.

"The third state challenges how scientists typically understand cell behaviour," said biologists Peter Noble and Alex Pozhitkov, co-authors of the review, in&nbsp;an essay for&nbsp;The Conversation.

According to the researchers, biological robots or biobots are able to develop new functions which set them apart, because "there are few instances where organisms change in ways that are not predetermined".

"Taken together, these findings demonstrate the inherent plasticity of cellular systems and challenge the idea that cells and organisms can evolve only in predetermined ways," Noble and Pozhitkov stated.&nbsp;

"The third state suggests that organismal death may play a significant role in how life transforms over time," they added.

This organism is not living or dead but is in a 'third state'. Here's what it means

Eastern Sierra Nevada's Mono Lake is harbouring a creature that has not been seen previously. Scientists have identified an unknown microscopic organism in the water body which can provide hints about complex animal life originated on Earth. It is a type of choanoflagellate, a single-celled microorganism, and is linked to animals.

The creatures found in the lake and animals that roam Earth have a common ancestor, which makes the discovery crucial in many ways. Scientists are hoping to understand how life transitioned from single-celled to multicellular.

"I'm fascinated by the origin of animals, but it turns out that you can't really study it from the fossil record because the first animals were small and squishy," co-author of the study, Nicole King, told Newsweek. He is a professor of molecular and cell biology at UC Berkeley.

He added that choanoflagellates have been known to be "the closest living relatives of animals" but "no one was studying them."

King adds in the study published online in the journal mBio that "choanos" can form multicellular colonies, similar to what transpired in the early stages of animal embryonic development. This is why they can prove helpful in understanding ancient evolutionary processes.

<h2>Mono lake contains&nbsp;cyanide</h2>

Mono lake has an inhospitable environment and " only the hardiest of extremophiles" can call it home, King says. "Mono lake is hypersaline; I think it has three times the salinity of the ocean and is hyperalkaline," King said. "It also contains high levels of toxins, including cyanide."

However, the discovery of the organism means that the lake has much more to offer. The Barroeca monosierra choanoflagellate interacts with bacteria in interesting ways.

One of them is quite an interesting one, where a single-celled organism suddenly becomes multicellular. "Certain bacteria can cause them to switch from being single-celled to multicellular," King said.

Bacteria can also cause choanos to mate. King said that they act like an aphrodisiac for the creature because they suddenly leave their solitary asexual lives and get together with these molecules.&nbsp;

California lake full of cyanide hiding previously unknown creatures

Scientists have found two never-before-seen groups of microbes that live in the hot springs of Yellowstone National Park,&nbsp;United States. The discovery, made by researchers from Montana State University, was published in the journal Nature on July 24.&nbsp;

The study, titled, "Cultivation and visualization of a methanogen of the phylum Thermoproteota", revealed that the new microbe groups are dubbed Methanomethylicia and Methanodesulfokora. They are methanogens, single-celled organisms that produce methane.&nbsp;

Methanogens, known to science since 1933, are methane-producing bacteria, especially an archaean which reduces carbon dioxide to methane, unlike humans and other animals who eat food, inhale oxygen and exhale carbon dioxide to survive.&nbsp;

The findings of the research may have implications for the search for extraterrestrial life and the fight against climate change.&nbsp;

It was earlier believed that all bacteria that produced methane belonged to a single phylum called Euryarchaeota. Now, the discovery of the two new microbial groupings confirms that methane-producing microorganisms are more diverse. They were previously only identified from DNA samples.&nbsp;

Methane is a gas that is 28 times more potent than carbon dioxide when it comes to trapping heat in the atmosphere.&nbsp;

In a statement, microbiologist Roland Hatzenpichler of Montana State, an author of the paper, said: "All we knew about these organisms was their DNA. No one had ever seen a cell of these supposed methanogens; no one knew if they actually used their methanogenesis genes, or if they were growing by some other means."&nbsp;

Two distinct study groups—one from China and the other from the US—have succeeded in cultivating these microorganisms in the lab, confirming that they actually produce methane.&nbsp;

The finding is significant as methanogens produce 70 per cent of the world's methane, with Hatzenpichler saying: "Methane levels are increasing at a much higher rate than carbon dioxide, and humans are pumping methane at a higher rate into the atmosphere than ever before."&nbsp;

Scientists are still trying to find out whether Methanomethylicia in non-extreme conditions grows by using methanogenesis or if they use some other mechanism.&nbsp;

They may be able to change the circumstances in their habitats and reduce the amount of methane released into the atmosphere if they comprehend this.&nbsp;

"My best bet is that they sometimes grow by making methane, and sometimes they do something else entirely, but we don't know when they grow, or how, or why. We now need to find out when they contribute to methane cycling and when not," Hatzenpichler said.&nbsp;

Scientists have now found new fossil records which tell us something about the animal kingdom and its existence on Earth which remained hidden for 2.1 billion years.&nbsp;

In the new study of fossils, scientists stumbled upon the mould-like unicellular organism, who were identified to be all complex life's common ancestor on Earth and is likely to have existed a billion years ago than what was earlier estimated.

However, a team of scientists from Cardiff University found that the evidence of the ecosystem had been present in the Franceville Basin near Gabon on the Atlantic coast of Central Africa more than 1.5 billion years earlier.

Speaking to BBC News, Cardiff University’s professor Ernest Chi said, “We’re saying, look, there’s fossils here, there’s oxygen, it’s stimulated the appearance of the first complex living organisms.”

“We see the same process as in the Cambrian period, 635 million years ago — it helps back that up. It helps us understand ultimately where we have all come from,” he added.

The US state of Texas recently issued a disaster declaration after a six-year-old boy who was infected with a brain-eating amoeba died. The child died on September 8 after the brain-eating amoeba was found in the community’s water supply.&nbsp;

The amoeba in question - Naegleria Fowleri is a micro-organism which can live in freshwater bodies as well as unhygienic swimming pools. Once the amoeba enters the body through one’s nasal membranes, it goes straight for the brain, and causes migraines, vomiting, hyperthermia, and even hallucinations.

Local media reported that traces of amoeba were found in the garden hose of the kid’s home. More traces were found in a fountain as well as a fire hydrant in an area which is merely an hour away from Houston.

Josiah McIntyre, the child possibly came in contact with contaminated water while playing at a splash park, according to his grandparents.

The park has been ordered shut, and an advisory has been commissioned warning people against using tap water for drinking, cooking, and bathing. Even though this advisory has been lifted since then, the authorities are urging people to boil water before using it.

On Sunday, Texas Governor Greg Abbott had issued a disaster declaration for Brazoria County, which will enable authorities to use extra state resources due to the emergency.

The affected cities are Lake Jackson, Freeport, Angleton, Brazoria, Richwood, Oyster Creek, Clute and Rosenberg, Texas, along with the Dow Chemical plant in Freeport and the Clemens and Wayne Scott Texas Department of Criminal Justice corrections facilities.

These infections are rare, but can be fatal. As per the data provided by the CDC, nearly 145 people were infected from 1962 to 2018 and only four survived the infection.
