For the First Time in 240 Years, White-Tailed Eagles Spotted Flying Over England

Eagles had been nearly hunted to extinction throughout England, Ireland, Scotland, and Wales—but researchers are saying they are now making a triumphant return.

In Ireland’s majestic Glenveagh National Park, golden eagles had disappeared until 2001 when—with the help of the Golden Eagle Trust—birds collected from eyries in Scotland were released into the park, which now boasts a stable population of the majestic birds.

In England, white-tailed eagles had become extinct on the coasts and cliffs of Great Britain. Also known as sea eagles, they are one of the largest eagle species on Earth.

Now, 240 years after the last sighting, a mature white-tailed eagle was confirmed soaring in the wild high over the North York Moors. This is the direct result of several eaglets that were released onto the cliff sides on the Isle of Wight.

Also collected under a Scottish National Heritage license from the same populations that Glenveagh drew from, the sea eagle project is part of a 5-year strategy managed by the Roy Dennis Wildlife Foundation and Forestry England to bring eagles back.

A team of experts and dedicated volunteers insured the birds were happy and healthy all the way to adulthood when they were released back along the wilds of the south coast, where the team has worked to provide feeding stations that would encourage the majestic birds to make that area home, rather than journey into human civilization and risk the danger of being struck by a windmill, glass building, or some other hazard.

Roy Dennis, the man behind the plan said:

“I have spent much of my life working on the reintroduction of these amazing birds and so watching them take to the skies of the Isle of Wight has been a truly special moment. Establishing a population of white-tailed eagles in the south of England will link and support emerging populations of these birds in the Netherlands, France and Ireland, with the aim of restoring the species to the southern half of Europe. The team is pleased that the project fulfills one of the specific aims of the Government’s 25 year Environment Plan.”

Due to its central position, the Isle of Wight is the perfect habitat for these birds’ reintroduction into the English coastline, as they have ample opportunity to spread out along for tens miles of coastland both east and west. The cliffs are secluded and predator-free environments for chicks to grow up in, and the surrounding sea provides ample sources of food, like grey mullet.

On the Roy Dennis Wildlife Foundation website, Roy blogs semi-regularly about the wanderings of the eagles around the country, tracking them via radio-transmitters on their legs. After a sedentary winter, one of the eagles flew from Oxfordshire to North York Moors National Park, a distance of 200 miles in 15 days.

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’

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.”

Scientists Develop Near Invincible Textile Coating That Can Repel Almost Anything

Scientists Develop Near-Invincible Textile Coating That Can Repel Blood, Bacteria, and Even Viruses

Masks, gowns, and other personal protective equipment (PPE) are essential for protecting healthcare workers—however, the textiles and materials used in such items can absorb and carry viruses and bacteria, inadvertently spreading the disease the wearer sought to contain.

When the coronavirus spread amongst healthcare professionals and left PPE in short supply, finding a way to provide better protection while allowing for the safe reuse of these items became paramount.

Thankfully, researchers from the LAMP Lab at the University of Pittsburgh Swanson School of Engineering may have a solution. The lab has created a textile coating that can not only repel liquids like blood and saliva but can also prevent viruses from adhering to the surface. The work was recently published in the journal ACS Applied Materials and Interfaces.

“Recently there’s been focus on blood-repellent surfaces, and we were interested in achieving this with mechanical durability,” said Anthony Galante, PhD student in industrial engineering at Pitt and lead author of the paper. “We want to push the boundary on what is possible with these types of surfaces, and especially given the current pandemic, we knew it’d be important to test against viruses.”

What makes the coating unique is its ability to withstand ultrasonic washing, scrubbing and scraping. With other similar coatings currently in use, washing or rubbing the surface of the textile will reduce or eliminate its repellent abilities.

“The durability is very important because there are other surface treatments out there, but they’re limited to disposable textiles. You can only use a gown or mask once before disposing of it,” said Paul Leu, co-author and associate professor of industrial engineering, who leads the LAMP Lab. “Given the PPE shortage, there is a need for coatings that can be applied to reusable medical textiles that can be properly washed and sanitized.”

Galante put the new coating to the test, running it through tens of ultrasonic washes, applying thousands of rotations with a scrubbing pad (not unlike what might be used to scour pots and pans), and even scraping it with a sharp razor blade. After each test, the coating remained just as effective.

The treatment consists of polytetrafluoroethylene (PTFE) nanoparticles in a solvent thermally sintered to polypropylene microfibers. PTFE is stable and nontoxic at temperatures lower than 260 °C (500 °F).

The researchers worked with the Charles T. Campbell Microbiology Laboratory’s Research Director Eric Romanowski and Director of Basic Research Robert Shanks, in the Department of Ophthalmology at Pitt, to test the coating against a strain of adenovirus.

“As this fabric was already shown to repel blood, protein and bacteria, the logical next step was to determine whether it repels viruses. We chose human adenovirus types 4 and 7, as these are causes of acute respiratory disease as well as conjunctivitis (pink eye),” said Romanowski. “It was hoped that the fabric would repel these viruses similar to how it repels proteins, which these viruses essentially are: proteins with nucleic acid inside. As it turned out, the adenoviruses were repelled in a similar way as proteins.”

The coating may have broad applications in healthcare: everything from hospital gowns to waiting room chairs could benefit from the ability to repel viruses, particularly ones as easily spread as adenoviruses.

“Adenovirus can be inadvertently picked up in hospital waiting rooms and from contaminated surfaces in general. It is rapidly spread in schools and homes and has an enormous impact on quality of life—keeping kids out of school and parents out of work,” said Shanks. “This coating on waiting room furniture, for example, could be a major step towards reducing this problem.”

The next step for the researchers will be to test the effectiveness against betacoronaviruses, like the one that causes COVID-19.

“If the treated fabric would repel betacornonaviruses, and in particular SARS-CoV-2, this could have a huge impact for healthcare workers and even the general public if PPE, scrubs, or even clothing could be made from protein, blood-, bacteria-, and virus-repelling fabrics,” said Romanowski.

At the moment, the coating is applied using drop casting, a method that saturates the material with a solution from a syringe and applies a heat treatment to increase stability. But the researchers believe the process can use a spraying or dipping method to accommodate larger pieces of material, like gowns, and can eventually be scaled up for production.
