Scott C Waring, a self-proclaimed alien researcher who operates from Taiwan, is one of the most prominent figures in the UFO community. The researcher has been releasing some mindblowing UFO videos over the past few years, and he believes these clips are proof of extraterrestrial existence.Throughout his career, Waring has blamed NASA and the government for covering up realities about alien life, and now he has targeted search engine giant Google for working ‘hand-in-glove’ with the authorities to censor facts of extraterrestrial existence from the general public.In a recent post on his website ‘UFO Sightings Daily’, Waring alleged that Google is intentionally trying to target UFO researchers in order to make sure that their content is not reaching the fingertips of internet users.”Google owns the platform my UFO Sightings Daily site is on, Google owns Youtube, Google owns Adsense. DO YOU SEE A PATTERN YET? Because I sure do. UFO researchers worldwide are being attacked by Google, which is an organisation worldwide controlling information that people are allowed to see. That Google itself is attempting to clean up and delete the UFO community from the Internet. We are under attack by Google,” wrote Waring on his website.A few months back, after spotting a fossil-like structure on Mars, Waring had urged United States president Donald Trump to appoint him as the head of NASA. In his web post, Waring claimed that he will disclose all secrets about alien life if he gets a chance to work as the head of the United States space agency.The comments from Waring came just a few days after a streak of pulsating UFOs were spotted in England. The clip of this bizarre incident was released by conspiracy theory YouTube channel ‘Mavixxx’, and it made many people believe that an alien invasion is imminent.

5 statesmen shaped the post-World War I eraThe Great War changed the world as empires collapsed, new nations were created and powerful political figures emerged, going on to set the agenda for a new order.Here are brief profiles of five of the leading figures of World War I and its aftermath.- US: Thomas Woodrow Wilson -Democratic president Thomas Woodrow Wilson (1856-1924) won re-election in 1916 on a campaign of keeping the United States out of the conflict in Europe, even though Washington was helping finance the Allied war effort.But this changed after German submarines sank US ships crossing the Atlantic and he sent the first troops over in April 1917.Wilson was a key player in the post-war negotiations in Paris in 1919 and the resulting Versailles Treaty was based on his “Fourteen Points” for peace.They included the creation of a body that became the League of Nations, the precursor to today’s United Nations, and provisions on sovereignty and open diplomacy.He was awarded the Nobel Peace Prize in 1920.- France: Georges Clemenceau -Nicknamed “The Tiger”, the hardline Republican Georges Clemenceau (1841-1929) was appointed French prime minister in 1917, when Allied victory seemed uncertain.With a fierce resolve for victory, he centralised and stimulated the war effort while gaining strong popular backing in part because of his regular visits to the front line.Also one of the architects of the Versailles Treaty, he was less open than his US and British allies to compromise with the Germans, insisting on punishing terms and vowing “Germany will pay”.- Britain: David Lloyd George -David Lloyd George (1863-1945) was a Liberal party pacifist who converted to rally behind the war, first as minister of munitions in 1915 and then as war minister and a galvanising prime minister in 1916.Dynamic and determined, he boosted public morale and brought new energy and organisation, creating the civil infrastructure to support the troops and unifying the Allied military command in 1917.Lloyd George represented Britain at the Paris Peace Conference and remained prime minister until 1922.- Russia: Vladimir Lenin -Marxist Bolshevik revolutionary Vladimir Ilich Ulyanov (1870-1924) lived mostly abroad during the war, which he opposed as “imperialist”.He returned home in February 1917, with the help of the Germans who hoped he would weaken their Russian enemy, and convinced fellow Bolsheviks to revolt in October.A supporter of an immediate peace with Germany, the founder of the Communist Party was the driving force in Russia for the Brest-Litovsk Treaty (1918) which ended the fighting at the cost of Moscow ceding massive areas of territory and more than 30 percent of its population.- Turkey: Mustafa Kemal Ataturk -A colonel and then general in the Ottoman army, Mustafa Kemal Ataturk (1881-1938) led the victory against the Allies in the Gallipoli campaign in 1915.He went on to head a nationalist movement that fiercely opposed the 1920 Treaty of Sevres between the Allies and the Ottoman empire and which led to the latter’s dismantling.As the Allies tried to carve up the empire, Ataturk commanded an army that re-conquered Armenia and Kurdistan and drove the Greeks out of Asia Minor. He became president in 1923 and is considered the father of modern Turkey.
(PhysOrg.com) — Physicists in Italy have discovered the first evidence of a rare nucleus that doesn’t exist in nature and lives for just 10-10 seconds before decaying. It’s a type of hypernucleus that, like all nuclei, contains an assortment of neutrons and protons. But unlike ordinary nuclei, hypernuclei also contain at least one hyperon, a particle that consists of three quarks, including at least one strange quark. Hypernuclei are thought to form the core of strange matter that may exist in distant parts of the universe, and could also allow physicists to probe the inside of the nucleus. The FINUDA experiment is located at one of the two interaction points of the DAFNE collider at INFN-LNF. As Elena Botta, a lead collaborator in the study, explained, DAFNE produces electron and positron beams. When these beams collide nearly head-on, they produce the phi meson (Φ), which decays with a 50% probability into a charged pair of K and anti-K mesons. FINUDA’s interaction point contains an octagonal prism with eight targets along the sides. When the anti-K meson interacts with a lithium nucleus in one of these targets, it can simultaneously produce a 6ΛH hypernucleus and a π+ meson of a particular energy. If scientists detect this particular meson, they’ve detected a signature of the strange nucleus formation. As Botta explained, 6ΛH production involves a two-step mechanism to decrease the number of protons in the lithium isotope, 6Li, from three to one, which produces hydrogen. Once produced, the neutron-rich 6ΛH hypernuclei slow down inside the target, and after 10-10 seconds they decay at rest into a π- meson and a 6He nucleus. The π- meson also has a particular energy, and scientists can easily detect it to give the signature of the decay. So both the formation and the decay of 6ΛH hypernuclei can be detected by searching for events with the presence of these particular π+ and π- mesons. Strange matterAs the first evidence for 6ΛH hypernuclei, the results could shed light on strange matter, which is hypothesized to exist at the center of ultra-dense neutron stars. The physicists hope to investigate strange matter further by producing strange nuclear systems.“Hypernuclei can be interpreted as the core of strange matter,” Botta told PhysOrg.com. “In particular, the possibility to produce strange nuclear systems containing two Λ particles will allow us to study the interaction between strange particles.”Hypernuclei could also serve as a useful tool to investigate the current model of nuclear structure, in which protons and neutrons are arranged in a stable configuration. “The fact that a hypernucleus has a strange quark does give it interesting characteristics compared to normal nuclei, since it allows the component L particle to act as a probe that can go very deep into the nucleus to test the description that the single particle shell model gives of nuclear matter,” Botta said. “In this respect, the study of hypernuclear physics allows us to get information not directly accessible otherwise.”She added that other hypernuclei with large neutron-to-proton ratios could exist in a stable state, even though ordinary neutron-rich nuclei are theoretically unstable. Neutron-rich hypernuclei seem to be an exception because of the way they modify the structure of a nucleus and increase its lifetime. During an upcoming experiment at the Japan Proton Accelerator Research Complex (J-PARC), physicists plan to search for 6ΛH as well as for other neutron-rich hypernuclei, such as lithium 10 Lambda (10ΛLi). Journal information: Physical Review Letters The particular hypernucleus investigated here, called “hydrogen six Lambda” (6ΛH), was first predicted to exist in 1963. Now, in a study published in a recent issue of Physical Review Letters, physicists working in the FINUDA experiment at the Istituto Nazionale di Fisica Nucleare – Laboratori Nazionali di Frascati (INFN-LNF) in Frascati, Italy, have reported finding the first evidence for the particle. The FINUDA collaboration’s analysis of millions of events has turned up three events for the rare hypernucleus. Strange propertiesAs its name suggests, 6ΛH is a large type of hydrogen nucleus that consists of six particles: four neutrons, one proton, and one Lambda (Λ) hyperon. Since an ordinary hydrogen nucleus contains one proton and no neutrons, hydrogen nuclei that contain one or more neutrons are sometimes called “heavy hydrogen.” The most common types of heavy hydrogen are deuterium (which has one neutron) and tritium (which has two neutrons). Since 6ΛH has four neutrons plus a L hyperon, physicists refer to it as “heavy hyperhydrogen.”The L hyperon, which consists of one up, one down, and one strange quark, does an even more interesting thing to 6ΛH: it increases its lifetime from 10-22 seconds (the lifetime of the hypernucleus core 5H without L) to 10-10 seconds. When scientists first discovered the L hyperon in 1947, they observed a similarly longer lifetime than predicted for this “strange” object. That observation led to the idea of the existence of the strange quark, with strangeness being the property that causes the quark to live so long.DetectionWithout the L hyperon, it would likely be impossible for physicists to directly observe a hydrogen nucleus with four neutrons, since such a heavy isotope is very difficult to produce and has a very short lifetime. Another hypernucleus, 4ΛH, which has two neutrons instead of four, is more easily produced than 6ΛH in similar experiments and has been detected many times. But detecting evidence of 6ΛH is much more difficult. The 27 million collision events analyzed by the FINUDA collaboration represents about one full year of continuous data-taking from an experiment that spanned several years. Theoretically, the formation probability of 6ΛH is at least 100 times smaller than that of 4ΛH. Explore further Nuclear physics incorporates a ‘strange’ flavor More information: M.

Play Drops of cold liquid SF6SF6 fall through an atmosphere of helium gas containing SF6SF6 vapor. Each drop, by cooling the surrounding vapor, creates a burst of tiny SF6SF6 droplets in its wake. The experiment illustrates a basic process of droplet seeding that may contribute to rain formation in the Earth’s atmosphere. Credit: P. Prabhakaran et al., Phys. Rev. Lett. (2017) They report that some of the sulphur hexafluoride pooled at the bottom of the tank and some of it remained as a gas in the upper portions of the tank. But then, the sulphur hexafluoride began to form droplets on the top of the box, which eventually detached, falling through the gas to land in the pool below. But the team found that as they fell, they caused smaller droplets to form in their wake—this was because the drops were colder than the gas they were passing through. These smaller drops than fell into the pool below as rain.The researchers acknowledge that they have no evidence that their experiment mimicked nature, but note that if something similar is happening in the atmosphere, it could explain the onset of sudden rainstorms. © 2017 Phys.org Contrast enhanced image sequence of an SF6 drop falling through the gaseous SF6-He layer.

Similarly, scientists are still baffled by sudden rainstorms. Why do some clouds suddenly release rain while others that appear nearly identical do not? No one knows, because the factors at play in rain clouds are too difficult to study. For that reason, scientists are trying to recreate atmospheric conditions in the lab or via computer simulations. Unfortunately, neither approach has led to answers regarding sudden rainstorms. In this new effort, the researchers have taken a new approach to better understand rainstorms.Because it is difficult to mimic normal upper atmospheric conditions in a lab container, the researchers chose to use sulphur hexafluoride as a stand-in for water in the atmosphere because it can exist as a liquid and a gas at surface level pressure and also because it forms into droplets when chilled. They used helium as a stand-in for general atmospheric gasses. The chemicals were pumped into a box which was then heated slightly on the bottom and chilled slightly at the top. The researchers used a high-speed camera to film the action. (Phys.org)—A team of researchers from Germany, France and the U.S. has found a possible explanation for the onset of sudden rainstorms. In their paper published in the journal Physical Review Letters, the group describes experiments they conducted with stand-ins for water and atmospheric gases in a box in their lab and what they witnessed.

DOI: 10.1103/PhysRevLett.119.128701 , On Arxiv: https://arxiv.org/abs/1705.10501AbstractWe present results from moist convection in a mixture of pressurized sulfur hexa-flouride (liquid and vapor) and helium (gas) to model the wet and dry components of the earth’s atmosphere. To allow for homogeneous nucleation, we operate the experiment close to critical conditions. We report on the nucleation of microdroplets in the wake of large cold liquid drops falling through the supersaturated atmosphere and show that the homogeneous nucleation is caused by isobaric cooling of the saturated sulfur hexaflouride vapor. Our results carry over to atmospheric clouds: falling hail and cold rain drops may enhance the heterogeneous nucleation of microdroplets in their wake under supersaturated atmospheric conditions. We also observed that under appropriate conditions settling microdroplets form a rather stable horizontal cloud layer, which separates regions of super and sub critical saturation.
