University of Bristol research into octopus vision has led to a quick and easy test that helps optometrists identify people who are at greater risk of macular degeneration, the leading cause of incurable sight loss. The basis for this breakthrough was published in the latest issue of the Journal of Experimental Biology and describes new technology developed by lead researcher, Professor Shelby Temple, to measure how well octopus—which are color-blind—could detect polarized light, an aspect of light that humans can't readily see. Using this novel technology, the research team showed that octopus have the most sensitive polarization vision system of any animal tested to date. Subsequent research used the same technology in humans and led to the development of a novel medical device that assesses the risk factor for sight loss later in life. Prof Shelby Temple, who holds honorary positions at the School of Biological Sciences, University of Bristol and the School of Optometry, Aston University, explained the impact of the team's findings. He said: "We knew that octopus, like many marine species, could see patterns in polarized light much like we see color, but we had no idea that they could do so when the light was only 2% polarized—that was an exciting surprise, but even more surprising was when we then tested humans and found that they were able to see polarization patterns when the light was only 24% polarized. "Humans can perceive polarized because macular pigments in our eyes differentially absorb violet-blue light depending on its angle of polarization, an effect known as Haidinger's brushes. It's like a super sense most of us don't even know we have, revealing a faint yellow bow-tie shape on the retina. The more of these pigments a person has, the better protected they are against sight-loss. Octopus eye. Credit: Prof Shelby Temple "By inventing a method to measure polarization vision in octopuses, we were able to use the core technology to develop a novel ophthalmic device that can quickly and easily screen people for low macular pigments, a strong risk factor for increased susceptibility to macular degeneration." Macular pigments are the body's natural protection against damaging violet-blue light. This new testing approach enables optometrists to provide preventative advice to patients. Empowering patients to make simple lifestyle choices, like wearing sunglasses or eating more dark green and brightly colored fruits and vegetables that can help them protect their sight through life. Prof Temple said, "I am so happy this work has been published, as it was the foundation upon which we developed our exciting new technology for measuring macular pigments." Macular pigments are the carotenoids lutein, zeaxanthin and meso-zeaxanthin that we can only acquire from our diet. They provide long term protection to the retina and this helps prevent age-related macular degeneration by acting as antioxidants and by strongly absorbing the most damaging high energy visible (violet-blue) wavelengths (380-500 nm) of light that reach our retina. A challenge to the eye care industry is that it is not possible to determine someone's macular pigment levels without measurement, and until now most techniques have been too time consuming, difficult, or expensive to become part of regular eye exams. The new technology developed by Prof Temple through his start-up company Azul Optics Ltd, enables rapid screening of macular pigment levels and can be used on patients from 5 -95 years of age. Prof Temple added: "We are all living longer and expecting to do more in our older age, so I hope this serendipitous invention will help empower people to do more to look after our eyes, so they don't suffer from this devastating disease." https://phys.org/news/2021-05-insights-color-blind-octopus-human-sight.html

Scientists have known for some time that many species of bats use echolocation to determine how far away an object is from them. They send out a signal and then measure its distance by the amount of time that it takes for the signal to bounce back to them. What is not known is whether this ability is something they are born with or if it is learned. To answer that question, the researchers conducted two kinds of experiments—one with bats reared in the lab, the other with captured wild bats. The first experiment involved raising bats from when they were pups until they were old enough to find food on their own. Each was trained to eat from a certain target placed 130 cm away from a starting perch. Some of the bats were raised in an environment with added helium in the air—helium is thinner than air, thus sound travels faster when passing through it. Each of the bats were then tested under two scenarios. In the first, the bats were tested on their ability to reach the target under normal conditions—they were also timed. In the second scenario, the bats were tested in the same ways as they flew in helium-enriched air. The researchers found that those flying in helium-enhanced air tended to underestimate the distance to the target—and it did not matter if they were raised in a helium-rich environment or not. In the second experiment, the researchers caught and trained several wild bats and taught them to eat from the same target as the bats in the first experiment. They then ran the same tests as they did in the first experiment and obtained the same results. The bats flying in helium-enriched air tended to underestimate the distance to the target. The researchers therefore suggest that bats have an innate sense of the speed of sound. https://phys.org/news/2021-05-innate.html

A new focus article in the May issue of Geology summarizes research on plastic waste in marine and sedimentary environments. Authors I.A. Kane of the Univ. of Manchester and A. Fildani of the Deep Time Institute write that "Environmental pollution caused by uncontrolled human activity is occurring on a vast and unprecedented scale around the globe. Of the diverse forms of anthropogenic pollution, the release of plastic into nature, and particularly the oceans, is one of the most recent and visible effects." The authors cite multiple studies, including one in the May issue by Guangfa Zhong and Xiaotong Peng. Zhong and Peng were surprised to find plastic waste in a deep-sea submarine canyon located in the northwestern South China Sea. "Plastic is generally considered to be the dominant component of marine litter, due to its durability and the large volume produced," write Kane and Fildani. "Nano- and microplastics are a particularly insidious form of anthropogenic pollutant: tiny fragments and fibers may be invisible to the naked eye, but they are ingested with the food and water we consume and absorbed into the flesh of organisms." One of their vital questions is, "If some plastics can survive for >1000 years in terrestrial environments, how long do they last in ocean trenches that are kilometers deep, dark, cold, and at high pressure? How long does it take microplastic to break down into microplastics and nanoplastics in the deep sea?" "While it is incumbent on policy makers to take action now to protect the oceans from further harm, we recognize the roles that geoscientists can play," write Kane and Fildani. That includes using their deep-time perspective to address the societal challenges, their understanding of the present-day distribution on the seafloor and in the sedimentary record, using geoscience techniques to record the downstream effects of mitigation efforts, and to predict the future of seafloor plastics. In summary, they write, "We understand ... the transient nature of the stratigraphic record and its surprising preservation, and the unique geochemical environments found in deep-sea sediments. Our source-to-sink approach to elucidate land-to-sea linkages can identify the sources and pathways that plastics take while traversing natural habitats and identify the context in which they are ultimately sequestered, and the ecosystems they affect. This will happen by working closely with oceanographers, biologists, chemists, and others tackling the global pollution problem." https://phys.org/news/2021-05-plastic-pollution-deep-sea-geological.html

Gates-Funded Doctor Demands Terrorist Experts to Attack Me Most recently, Dr. Peter Hotez, president of the Sabin Vaccine Institute,6 which has received tens of millions of dollars from the Bill & Melinda Gates Foundation,7,8,9 — with funds from the foundation most recently being used to create a report called "Meeting the Challenge of Vaccine Hesitancy,"10,11 — also cited the CCDH in a Nature article in which he calls for cyberwarfare experts to be enlisted in the war against vaccine safety advocates and people who are "vaccine hesitant." He writes:12 "Accurate, targeted counter-messaging from the global health community is important but insufficient, as is public pressure on social-media companies. The United Nations and the highest levels of government must take direct, even confrontational, approaches with Russia, and move to dismantle anti-vaccine groups in the United States. Efforts must expand into the realm of cyber security, law enforcement, public education and international relations. A high-level inter-agency task force reporting to the UN secretary-general could assess the full impact of anti-vaccine aggression, and propose tough, balanced measures. The task force should include experts who have tackled complex global threats such as terrorism, cyber attacks and nuclear armament, because anti-science is now approaching similar levels of peril. It is becoming increasingly clear that advancing immunization requires a counteroffensive." Why is Hotez calling for the use of warfare tactics on American citizens that have done nothing illegal? In my case, could it be because I've written about the theory that SARS-CoV-2 is an engineered virus, created through gain-of-function research, and that its release was anticipated by global elites, as evidenced in Event 201? Comment: Why, indeed. This isn't about educating the public, it's about outright thought control at a level hitherto unheard of. Treating anyone that thinks 'outside the box' as a threat akin to terrorist groups. It's absolutely insane. It may be. At least those are some of my alleged "sins," detailed on page 10 of the CCDH report, "Disinformation Dozen: The Sequel."13 Coincidentally enough, the Nature journal has helped cover up gain-of-function research conducted at the Wuhan Institute of Virology, publishing a shoddy zoonotic origins study relied upon my mainstream media and others, which was riddled with problems.14,15 So, it's not misinformation they are afraid of. They're afraid of the truth getting out. They're all trying to cover for the Chinese military and the dangerous mad scientists conducting gain-of-function work.
