Lockheed's Skunk Works has a Patent for a Portable Fusion Reactor Design

Defense contractor Lockheed Martin was recently awarded a patent for a novel design of compact nuclear fusion reactor, a device presumably small enough to be housed in a standard shipping container. According to earlier promotional material released by the company, the reactor's compact design could be used not only for commercial energy-generating applications, but also incorporated into ocean-going ships and aircraft to vastly extend the vehicles' ranges. In terms of generating electricity for commercial use, the device could also be used to replace not only nuclear waste-producing fission reactors, but also fossil fuel-based electrical generators, dramatically reducing the carbon footprint of our civilization's thirst for energy.

Quarterly Climate Report: Global Temperatures Aren't Breaking Records, but they're Still Disturbingly Above Normal

According to the National Oceanic and Atmospheric Administration, global average surface temperatures for the first three months of 2018 have eased off of their record-breaking streaks seen in recent years, with January and March each being only the fifth warmest months for their respective months, and February coming in as the 11th hottest February in the 139-year record. While this trend looks good on the surface, NOAA points out that each of these months' temperatures are still well above the 20th century average, meaning we're still far from out of the global warming gutter.

Rhino, el asombroso vehículo anfibio con ruedas “burbuja”

Funcionamiento del aireador de Elie Aghnides. Fuente: LIFE. 5, de agosto de 1946.

Elie Prodromou Aghnides, inventor e ingeniero de origen griego nacido en 1901 y fallecido en 1988, desarrolló su carrera sobre todo en los Estados Unidos. Su invención más célebre, que data de los años treinta, nos acompaña desde hace décadas y apenas nos damos cuenta de que está ahí. Se trata de los aireadores para grifos y duchas: sí, son los filtros rociadores, con malla metálica, que están presentes en todos los grifos, esos que de vez en cuando hay que desenroscar para limpiarlos de arenillas y similares (los hay de mil tipos diferentes, pero en general son modelos evolucionados y perfeccionados de la idea original de Elie Aghnides). Esa invención, junto con muchas otras similares, como varios modelos de “alcachofa” de ducha, le hicieron millonario (por cierto, por si alguien se lo pregunta, un aireador para grifos mejora el sabor del agua, reduce posibles olores, lo filtra y, sobre todo, mejora el flujo y supone un ahorro de agua).

Elie comentaba que el origen de sus invenciones se encontraba en la observación de su entorno, de la vida cotidiana y la naturaleza. Por ejemplo, la idea de del aireador para grifos le llegó cuando contemplaba una cascada. Así, al siempre inquieto Elie se le iluminó de nuevo la bombilla de la invención cierto día al contemplar cómo trabajaban unas máquinas de obra pública en Nueva York. ¿Por qué no crear una máquina que reuniera las capacidades de un buldócer con la agilidad de un automóvil? Una cosa era tener la idea y otra muy diferente fue materializarla: le costó década y media llevar a la vida el prototipo de su Rhino (lo de llamarlo “rinoceronte” fue algo natural, pues el pesado prototipo tenía especial tendencia para salir airoso de los lugares llenos de barro).

No llegó a comercializarse, aunque el inventor pensó en el mercado de obras públicas y el militar como objetivos prioritarios (los militares estaban preocupados por lo sencillo que parecía perforar aquellas ruedas hemisféricas incluso con armas ligeras). El Rhino levantó pasiones durante un tiempo, pero terminó olvidándose. El prototipo se presentó en Indianápolis en 1954, siendo probado sobre todo tipo de terrenos difíciles: arenas, barro, pendientes, navegando sobre las aguas… todo un monstruo de cinco toneladas capaz de sobrevivir a todo tipo de terrenos peligrosos. Sus ruedas delanteras huecas, de acero y aluminio, eran espectaculares sobre todo por su diseño de media burbuja (las traseras eran ruedas convencionales con un suplemento hemisférico). Ese diseño, y su bajo centro de gravedad, permitía mantener controlado el vehículo incluso en condiciones de inclinación extrema y, además, facilitaban la navegabilidad en las aguas, siendo impulsado en ese caso por una especie de hidrojet.

Researchers Find New Evidence that the Early Solar System had More Planets


Researchers may have discovered direct evidence of a former sister planet that resided in our Solar System, but was obliterated during an unknown cataclysm that occurred billions of years ago. It is theorized that the Solar System may have had as many as ten such lost planets early in its history, but this new evidence takes such theories and brings them that much closer to reality.

Argentina: Alleged Contactee Experience in Salta

Argentina: Alleged Contactee Experience in Salta

Residents of Rosario de La Frontera, in northwestern Salta Province, claim that "extraterrestrial contact" took place in recent days by exchanging light signals.

Ezequiel Alvarez, chief of the local volunteer firefighters of that community, managed to capture strange lights that turn on and off and then merge on his own cellphone. One appears at first and is joined by two more on the scene. "At 21:30 hours on Monday we received a call advising us of the presence of two strange lights on the banks of the Rosario River. We headed there and had a shocking experience."

In the recording, the Rosario fire chief explains how red lights flashed on and off from the object. Their intensity, color and trajectory was variable.

"We made signals at them with a flashlight and they replied," he stated. With full conviction and certainty, Chief Alvarez went a step further and added that extraterrestrials "are members of the Pleiadan civilization" (sic). He bases this belief on the fact that "they are in contact with Alejandro Godoy, a local resident who is also a UFO buff, and was told that two craft were in the vicinity of the Rosario River and that he should head for the site. That's how he was able to tell me about what happened later on," Alvarez explained.

"They choose whom they want to make contact with in these displays, regardless of the individual's social, cultural or religious status. Godoy is much involved with phenomena of this type," said Alvarez. "I went to the site immediately and felt great excitement. I have had many contact experiences with extraterrestrial craft, but this is the first time that a video has been recorded in which they can clearly be seen to greet us. We were in material contact with the ship," he added.



In his story, Alvarez claimed that a light was visible at first, and then others began to come in and out of that central point. "What happened in the Rosario River area was startling, because it was only two kilometers from the urban zone. This was a preparation of sorts. They were telling us that they were at our doorstep and knocking at the door. I have no question that they'll continue to materialize."

"What's happening to me is wonderful. But I think it's also a warning to humanity due to the wars and the use of nuclear and chemical weaponry," he observed. Regarding the sighting on the Rosario River area, he explained that the craft were over some trees, some fifteen meters tall. "They have allowed themselves to be recorded and documented in order that everyone may be aware of this display and eyewitness testimony."

Alvarez said there were many UFO sightings in the Rosario de la Frontera region. "There are many paranormal issues we can discuss. I can tell you there are various civilizations operating in Rosario de la Frontera. There are documented cases in the area of Duraznito, where locals and farmers saw them on the mountains," said the volunteer fire chief.

It is believed that the Pleiadans are a collective of entities from the seven stars we have come to know as the Pleiades, says the El Tribuno de Salta newspaper on its website. UFO theorists say they are our ancestors, as they contributed their DNA to bring about the human race. For that reason they are known as our seminal group. Their biology is like our own, although their technical and spiritual development is greater than Earth's. Pleiadans have their own spiritual masters who have in turn offered to contribute to our own evolution. Their preferred way of doing so is by sharing their knowledge, as they consider "the light" to be information and "the dark" to be the absence of information.

Researchers have Developed a Device that can Listen to your Inner Voice

A research team at the Massachusetts Institute of Technology has developed a device that can listen to and transcribe a person's otherwise silent inner voice, to make that information available to record or transmit electronically--all without the user having to utter a word.

The device, called "AlterEgo" by its designers, makes use of a specialized headset that wraps around the back of the user's ear, with an extension placed along the jawline. It picks up on neuromuscular signals transmitted through the jaw and face, an unconscious result of the internal verbalizations being made by the individual. These signals are then interpreted by a machine-learning system that translates the patterns into words.

The Threat of UFO Invasion



The Threat of UFO Invasion
By Scott Corrales © 2018

"A communication disruption can only mean one thing: Invasion."
--Sio Bibble, Queen Amidala’s prime minister in Star Wars Episode I – Attack of the Clones

Despite the sage courtier’s assertion in the first installment of George Lucas’s second round of space epics, we might sooner believe that a planet-wide interruption of communications, or a collapse of the power grid, was due to a Carrington-level event more than an alien attack. Unless cloaking technology really exists, an alien fleet would be visible to our telescopes and hopefully our orbiting satellites, unless they too had been wiped out. Nevertheless, the opening rounds of an assault by hostile non-humans are the key moment of any science fiction movie. How would that translate into a real life event?

In November 1979, Thomas Muldoon, writing for the National Enquirer, published an article with the sensational headline: "Take UFOs Seriously or Be Prepared for Sneak Invasion by Space Aliens." Some may find it amusing to see this article included among the National Security Agency's cache of information on the subject of unidentified flying objects (https://ift.tt/1qR7giK), but the Enquirer was at the forefront of much UFO journalism in those days, as evidenced by the sterling work of the late Bob Pratt. The NSA report - "obtained exclusively by The ENQUIRER", as we are reminded - was aimed at dispelling the notion that UFOs were unworthy of scrutiny by the military/scientific establishment.

"If America does not start taking the sightings seriously, we leaver ourselves wide open to the possibility of a Pearl Harbor-type UFO invasion. The very fact that UFO phenomena have been witnessed all over the world from ancient times, and by considerable numbers of reputable scientists in recent times, now indicates rather strongly that UFOs are not all hoaxes, and if anything, rather than diminishing, the modern trend is toward increased reports from all sources."

So far so good. The nameless report, allegedly prepared in 1968, then moves on to scorn the "leisurely scientific approach" and urge a more determined response to fight the perceived threat of an alien invasion.

Carl Sagan had issued his own thoughts on the matter just two years earlier. “One of the primary motivations for the exploration of the New World,” he wrote, “was to convert the inhabitants to Christianity – peacefully if possible, forcefully if necessary. Can we exclude the possibility of an extraterrestrial evangelism? Can we conclude even darker motives? Might an extraterrestrial society want to be alone at the summit of galactic power and make a careful effort to crush prospective contenders? Or might there even be the cockroach response – to stamp out an alien creature simply because it is different?”

The concept of an interplanetary war in our times, a thought which admittedly smacks of the Cold War's "flying saucer" scare, has been seriously invoked by Gen. Douglas MacArthur in the 1950's and by President Ronald Reagan in the 1980's. NATO allegedly prepared a document evaluating the threat posed to existing conventional and military forces in the 1960's, conceding that "we virtually have no defense against their advanced technology." Serious researchers like the late Dr. Olavo Fontes analyzed the possibility that northern Brazil would be occupied by a UFO invasion force in the wake of the attack on the Itaipú garrison in 1965. in the Summer 1998 issue of the Samizdat newsletter, Brazilian researcher Oriel Farías told the world about the incredible and still little-known UFO wave that covered northeastern Brazil and which centered on the town of Guarabira. According to Farías, the outstanding characteristic of the '98 flap was the sheer variety of objects reported, ranging from standard disk-shaped craft to massive objects projecting powerful beams of light. "Lengths of 30 meters have been reported, the size of a 20-storey building," he writes. The Guarabira "invasion" began on March 3, 1998 and was spearheaded by 26 UFOs flying over the city at 6:45 p.m., when the lights went out in Guarabira, and lasting until 3:45 a.m., when power returned to the city. This blackout remains unexplained to this day.

Almost 500 witnesses all over France reported seeing a veritable invasion force of giant black triangles on November 5, 1990. In an article translated by author George Andrews from OVNI-MAGAZINE, a publication of the Banque Internationale de Données Ufologiques, it was said that "...The flight path of this armada of over 70 ships (that is the minimal figure) was at an altitude of 1000 meters (some 320 feet), sometimes over the horizon, flying a horizontal course after rapidly descending from the skies, following parallel trajectories distant from each other by 5 to 25 kilometers...Considering the facts of the matter altogether implies that a non-human intelligence and technology were responsible for the phenomena." The French space agency, CNES, based in Toulouse, ascribed the sightings to the disintegration of the Soviet Gorizont booster in the upper atmosphere, using a telex received from NASA to substantiate their claim, in spite of the serious discrepancies between the booster reentry times and those of the sightings. The sightings recorded by OVNI-MAGAZINE appeared to indicate toward craft of the same nature as those seen in Belgium and the U.S.: spotlights on the underside of the vehicle' hull, strobes which swept the ground, simultaneous activation and deactivation of the spotlights were among the common characteristics. It is interesting to note that when UFOs were reported above the Pyrenees on March 31 1993, the CNES once again sought to dismiss the sightings as the reentry of another Russian space booster that had lifted the "Cosmos" 2238 satellite into orbit the previous evening.

In 1981, Colin A. Phillips of UFO Research had the following words to share in a meeting held in Adelaide, Australia: “Thirty years after the great UFO invasion of Earth occurred, because no physical war was fought, the battle of the mind was lost. Those who have knowledge of this event and dare speak of it, have been drowned out with laughter and ridicule or destroyed by character assassination. The world audience with its provincial view, narrow horizons and vested interests, is not ready for this new concept. However, those who talked about swamp gas and degraded facts to clues, are still "sifting carefully through the evidence", creating UFO jargon, statistics and methods of investigation, trying to make a science of what all the time was a major historical event. The UFO visitations to Earth of the 1950's have subsided now and the real work of UFO groups should be to use the best evidence to inform governments and citizens of the real significance of this event on our future civilization. We should have an informed public in readiness should the events of the 1950’s be repeated.”

Un estudio constata la necesidad de incluir los gases de efecto invernadero en proyecciones climáticas regionales

Las variaciones de los niveles de CO2 y otros gases de efecto invernadero se incluyen en los modelos climáticos a escala global de forma documentada y coordinada, pero no siempre se hace en las predicciones regionales. Así lo señalan investigadores de la Universidad de Murcia en un estudio donde se indica que este carencia puede afectar a los modelos de alta resolución espacial.
