Scientists ‘Blown Away’ By Discovery of Longest Animal Ever Recorded—And It’s Quite Beautiful

An estimated 150-foot siphonophore—seemingly the longest animal ever recorded—was discovered during a month-long scientific expedition exploring the submarine canyons near Perth, Australia.

Additionally, up to 30 new underwater species were found by researchers from the Western Australian Museum aboard Schmidt Ocean Institute’s research vessel Falkor.

The discovery of this massive gelatinous string siphonophore—a floating colony of tiny individual zooids that clone themselves thousands of times into specialized bodies that string together to work as a team—was just one of the unique finds among some of the deepest fish and marine invertebrates ever recorded for Western Australia.

Scientists from the Western Australian Museum, led by Chief Scientist Dr. Nerida Wilson, were joined by researchers from Curtin University, Geoscience Australia and Scripps Institution of Oceanography in exploring the Ningaloo Canyons in the Indian Ocean. Using an underwater robot, ROV SuBastian, they completed 20 dives at depths of up to 4,500 meters (14,700 feet) over 181 hours of exploration.

During the expedition, scientists collected the first giant hydroids in Australia, discovered large communities of glass sponges in Cape Range Canyon, and observed for the first time in Western Australia the bioluminescent Taning’s octopus squid, long-tailed sea cucumber, and a number of other molluscs, barnacle and squat lobster species. Some of the species collected will be exhibited at the Western Australian Museum.

The team also found the largest specimen of the giant siphonophore Apolemia ever recorded—video of which was posted on Schmidt Ocean Institute’s Twitter account.

“We suspected these deep sea areas would be diverse but we have been blown away by the significance of what we have seen,” Wilson said. Added Dr. Lisa Kirkendale, head of aquatic zoology at the Western Australian Museum and co-principal investigator, “These specimens represent so many extensions in depth and range records for so many species, and will form an important new part of WA Museum collections.”

The expedition is part of Schmidt Ocean Institute’s year-long initiative in Australia and the Pacific to conduct a number of science and engineering expeditions with teams of scientists and researchers from around the world. Using the underwater robot SuBastian, scientists for the first time are able to explore deep sea canyons and coral reefs around Australia that have never been seen before. The footage and samples collected from the oceans that surround Australia will have important implications for the sustainability and protection of these underwater ecosystems—and for similar habitats worldwide that are in peril because of rising ocean temperatures and other environmental threats.

Owned and operated by Schmidt Ocean Institute, a philanthropic nonprofit established by Eric and Wendy Schmidt in 2009, Falkor is the only year-round seagoing philanthropic research vessel in the world. The vessel is equipped with a state-of-the-art 4,500 meter-capable underwater robotic system, ROV SuBastian, that was used to visually explore and collect samples from critical deep ocean areas that had not been explored before.

The ship and ROV are both made available to the international science community at no cost, and the scientists agree to make their discoveries publicly available. The collection data for these specimens will be made publicly available.

“There is so much we don’t know about the deep sea, and there are countless species never before seen,” said Wendy Schmidt, co-founder of Schmidt Ocean Institute. “Our planet is deeply interconnected–what happens in the deep sea impacts life on land–and vice versa. This research is vital to advance our understanding of that connection–and the importance of protecting these fragile ecosystems. The Ningaloo Canyons are just one of many vast underwater wonders we are about to discover that can help us better understand our planet.”

The science completed will allow the research team to formally describe many of the new species of animals that were found, develop ROV methodology for monitoring Marine Parks in Australia and screen deep water samples for environmental DNA in the Indian Ocean. The ROV SuBastian dives were livestreamed and are available in perpetuity on Schmidt Ocean Institute’s YouTube page, including video highlights, making the incredible diversity in the Ningaloo region available for the public to explore. The footage and specimens collected are important records within the Gascoyne Marine Park, serving as a permanent record of biodiversity in the canyons to build on in the future.

“Ongoing scientific exploration is vital to the effective management of our marine parks,” said Dr. James Findlay, director of Australia’s National Parks, who has been closely following the Falkor expedition, “and we are committed to partnering with other agencies to record and monitor these precious places.”

Chinese Rocket Segment Plunges Back To Earth, Crashes Near Maldives

Published

on

Beijing:

A large segment of a Chinese rocket re-entered the Earth’s atmosphere and disintegrated over the Indian Ocean on Sunday, the Chinese space agency said, following fevered speculation over where the 18-tonne object would come down.

Officials in Beijing had said there was little risk from the free falling segment of the Long March-5B rocket, which had launched the first module of China’s new space station into Earth orbit on April 29.

But the US space agency NASA and some experts said China had behaved irresponsibly, as an uncontrolled re-entry of such a large object risked damage and casualties.

“After monitoring and analysis, at 10:24 (0224 GMT) on May 9, 2021, the last-stage wreckage of the Long March 5B Yao-2 launch vehicle has re-entered the atmosphere,” the China Manned Space Engineering Office said in a statement, providing coordinates for a point in the Indian Ocean near the Maldives.

It added that most of the segment disintegrated and was destroyed during descent.

The US military’s Space Command said the rocket “re-entered over the Arabian Peninsula at approximately 10:15 pm EDT on May 8 (0215 GMT Sunday)”.

“It is unknown if the debris impacted land or water.”

Monitoring service Space-Track, which uses US military data, said that the location in Saudi Arabia was where American systems last recorded it.

“Operators confirm that the rocket actually went into the Indian Ocean north of the Maldives,” it tweeted.

The segment’s descent matched expert predictions that any debris would have splashed down into the ocean, given that 70 percent of the planet is covered by water.

Because it was an uncontrolled descent, there was widespread public interest and speculation about where the debris would land.

American and European space authorities were among those tracking the rocket and trying to predict its re-entry.

Accusations of negligence

Objects generate immense amounts of heat and friction when they enter the atmosphere, which can cause them to burn up and disintegrate. But larger ones such as the Long March-5B may not be destroyed entirely.

Their wreckage can land on the surface of the planet and may cause damage and casualties, though that risk is low.

Last year, debris from another Chinese Long March rocket fell on villages in the Ivory Coast, causing structural damage but no injuries or deaths.

That, and the one that came down Sunday, are tied for the fourth-biggest objects in history to undergo an uncontrolled re-entry, according to data from Harvard-based astronomer Jonathan McDowell.

The uncertainty and risks of such a re-entry sparked accusations that Beijing had behaved irresponsibly.

US Defense Secretary Lloyd Austin suggested last week that China had been negligent, and NASA Administrator Bill Nelson echoed that after the re-entry on Sunday.

“Spacefaring nations must minimize the risks to people and property on Earth of re-entries of space objects and maximize transparency regarding those operations,” Nelson said in a statement.

“It is clear that China is failing to meet responsible standards regarding their space debris.”

China’s space ambitions

To avoid such scenarios, some experts have recommended a redesign of the Long March-5B rocket — which is not equipped for a controlled descent.

“An ocean reentry was always statistically the most likely,” McDowell tweeted.

“It appears China won its gamble (unless we get news of debris in the Maldives). But it was still reckless.”

Chinese authorities had downplayed the risk, however.

“The probability of causing harm to aviation activities or (on people and activities) on the ground is extremely low,” foreign ministry spokesman Wang Wenbin said Friday.

Beijing has poured billions of dollars into space exploration to boost its global stature and technological might.

The creature can chomp through plastic, even polyethylene, a common and non-biodegradable plastic currently clogging up landfills and seas.

Scientists have discovered that wax worms can eat and biodegrade polyethylene, the rugged, common plastic used to make the shopping bags that are currently glutting landfill sites. The discovery was serendipitous. The findings, which were published in the journal Proceedings of the Royal Society B Tuesday, could guide efforts to find an effective biodegradation system to tackle plastic waste.

Researchers Use Gene-focusing on Breakthrough Against COVID-19 Cells With CRISPR Tool Called ‘PAC-MAN’

Researchers Use Gene-focusing on Breakthrough Against COVID-19
DOE / LAWRENCE BERKELEY NATIONAL LABORATORY, R.N. Zuckermann

A group of scientists from Stanford University is working with researchers at the Molecular Foundry, a nanoscience client office situated at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), to build up a quality focusing on, antiviral specialist against COVID-19.

Last year, Stanley Qi, an assistant professor in the departments of bioengineering, and chemical and systems biology at Stanford University and his team had begun working on a technique called PAC-MAN—or Prophylactic Antiviral CRISPR in human cells—that uses the gene-editing tool CRISPR to fight influenza.

Be that as it may, that all changed in January, when updates on the COVID-19 pandemic rose. Qi and his group were out of nowhere stood up to with a baffling new infection for which nobody had an unmistakable arrangement. “So we figured, ‘For what reason don’t we take a stab at utilizing our PAC-MAN innovation to battle it?'” said Qi.

Since late March, Qi and his team have been collaborating with a group led by Michael Connolly, a principal scientific engineering associate in the Biological Nanostructures Facility at Berkeley Lab’s Molecular Foundry, to develop a system that delivers PAC-MAN into the cells of a patient.

Like all CRISPR frameworks, PAC-MAN is made out of a chemical—for this situation, the infection murdering compound Cas13—and a strand of guide RNA, which orders Cas13 to pulverize explicit nucleotide successions in the coronavirus’ genome. By scrambling the infection’s hereditary code, PAC-MAN could kill the coronavirus and prevent it from repeating inside cells.

It’s all in the delivery

Qi said that the key test to deciphering PAC-MAN from a sub-atomic instrument into an enemy of COVID-19 treatment is finding a compelling method to convey it into lung cells. At the point when SARS-CoV-2, the coronavirus that causes COVID-19, attacks the lungs, the air sacs in a contaminated individual can get aroused and load up with liquid, seizing a patient’s capacity to relax.

“But my lab doesn’t work on delivery methods,” he said. So on March 14, they published a preprint of their paper, and even tweeted, in the hopes of catching the eye of a potential collaborator with expertise in cellular delivery techniques.

Soon after, they learned of Connolly’s work on synthetic molecules called lipitoids at the Molecular Foundry.

Lipitoids are a kind of engineered peptide imitate known as a “peptoid” first found 20 years prior by Connolly’s tutor Ron Zuckermann. In the decades since, Connolly and Zuckermann have attempted to create peptoid conveyance atoms, for example, lipitoids. Also, as a team with Molecular Foundry clients, they have exhibited lipitoids’ adequacy in the conveyance of DNA and RNA to a wide assortment of cell lines.

Today, researchers studying lipitoids for potential therapeutic applications have shown that these materials are nontoxic to the body and can deliver nucleotides by encapsulating them in tiny nanoparticles just one billionth of a meter wide—the size of a virus.

Now Qi hopes to add his CRISPR-based COVID-19 therapy to the Molecular Foundry’s growing body of lipitoid delivery systems.

In late April, the Stanford researchers tested a type of lipitoid—Lipitoid 1—that self-assembles with DNA and RNA into PAC-MAN carriers in a sample of human epithelial lung cells.

As per Qi, the lipitoids performed well indeed. At the point when bundled with coronavirus-focusing on PAC-MAN, the framework decreased the measure of engineered SARS-CoV-2 in arrangement by over 90%. “Berkeley Lab’s Molecular Foundry has furnished us with an atomic fortune that changed our examination,” he said.

The team next plans to test the PAC-MAN/lipitoid system in an animal model against a live SARS-CoV-2 virus. They will be joined by collaborators at New York University and Karolinska Institute in Stockholm, Sweden.

If successful, they hope to continue working with Connolly and his team to further develop PAC-MAN/lipitoid therapies for SARS-CoV-2 and other coronaviruses, and to explore scaling up their experiments for preclinical tests.

“An effective lipitoid delivery, coupled with CRISPR targeting, could enable a very powerful strategy for fighting viral disease not only against COVID-19 but possibly against newly viral strains with pandemic potential,” said Connolly.

“Everybody has been working nonstop attempting to think of new arrangements,” included Qi, whose preprint paper was as of late companion looked into and distributed in the Journal Cell. “It’s exceptionally compensating to join skill and test new thoughts across establishments in these troublesome occasions.”
