  • Video: Laacher Lake super volcano awakens, threatens Europe

    The German volcano lying under Laacher See or Laacher Lake near Bonn (37 km) and Koblenz (24 km), is usually active once every 10000-12000 years, and its last eruption occurred 12,900 years ago. Lately, there have been many earthquakes in the region, a clear sign that the volcano is very likely to become active. Besides that, the activity is confirmed by the dozens mofettes in the Laacher See area (see video below).

    Lake See Volcano has about the same size as Mount Pinatubo, which in 1991 caused the largest eruption of the twentieth century. Pinatubo released into the air 10 billion tons of magma, 20 billion tons of sulfur dioxide and 16 cubic kilometers of ash, causing a decrease in global temperatures by 0.5 degrees Celsius.

    When it last erupted, the Laacher See super volcano splashed ash and volcanic rocks that covered an area of 1,600 square kilometers. In recent years, several earthquakes occurred in this region, suggesting that the volcano becomes active again.

    In 2011, thousands of dead birds were found in several American cities, but also in Sweden. It turned into a global hysteria when, at the same time, a huge crab colony failed in the UK and dozens of tons of fish were found dead in Brazil and New Zealand.

    World-first hybrid shark have been spotted in Australian waters (scroll down for photo).

    That’s a proof of survival adaptation as the ocean temperatures are influenced by the global warming. The hybridizing effect on the sharks can make their swimming span over a larger range of temperatures and therefore larger distances.

  • VIDEO: Orca vs shark fight in New Zealand waters

    Viral video shows incredible images of a male orca attacking a shark in shallow waters at Blue Cliffs Beach off New Zealand coasts (scroll down for stunning video and photos).

    Residents living in the nearby area had the “once-in-a-lifetime” chance to see for themselves who wins the clash between the sea titans.

    The confrontation was extremely long (about 2 hours) and marine biologist Clinton Duffy believes there were more orcas and sharks getting involved in the fight. Many times orcas – known as killer whales -, get into the surfing area to gather large mass of fish. No one knows what the outgunned shark was doing there but certainly he was at the wrong location, at the wrong moment.

    According to eye-witnesses about 6 orcas and 6 sharks are estimated to have participated in the spectacular natural display.

    How did the deadly game end?
    Well, the only chance for the shark to escape orca’s fierce assault, was to head toward the shore but unfortunately he ended up stranded on the beach. However the “Jaws” could not find peace on land as well because Peter Robertson’s “brave” dog engaged into action. A dog harassing the shark? This must be something rare to see:)

According to Robertson, “It looked like the whales were fighting the sharks … the sharks were coming towards shore because they prefered not to be in the water.”

    So far, it’s unclear what species the beaten sharks were. In any case, they appeared to be much smaller than the orcas and would have ended up worse in most confrontations.

    The fact that an orca wins over a shark does not come as something surprising. Let’s not forget that in general orcas are stronger, bigger, swifter and heavier that EVEN the most fearful sea creature, i.e. the great white shark.

    The mastermind behind the unique phenomenon seemed to be the…sea. Due to strong winds which blew up to 150 kilometers per hour, huge waves formed and beat the shoreline leaving mountains of foam behind. The foam was subsequently spread by wind gusts along the streets of the town.

    An unknown metallic ball of quite significant size plummeted from outer space to Namibian soil fact which determined the puzzled African officials to get in touch with world’s top space agencies such as NASA and ESA.

    The UFO has a radius of 17.5 centimeters and was located close to a village in Northern Namibia about 700 km from capital Windhoek.

    Acording to various witnesses, some blasts were heard a couple of days before the incident. The enigmatic ball featuring a rough surface and apparently comprising 2 half-spheres soldered together, is made of a “metal alloy known to man” and has 6 kilograms in weight.

  • Video: Shroud of Turin shows original Jesus image, Italian experts say

    Investigation carried out by Italian scientists reveals that the Shroud of Turin is most probable authentic, but the experts have not agreed yet with a ultimate 100% hypothesis (scroll down for video).

    Turin Shroud puzzling the believers once again. Photo: google images
    Dozens studies on Jesus’ thought-to-be burial cloth have sparked a string of contradictory reports related to the shroud’s authenticity.

    Yet, researchers from Italy’s National Agency for New Technologies, Energy and Sustainable Economic Development are pretty confident that their discoveries undermine previous theories that the shroud was forged during the medieval time. The new results appears to ignite controversial debates again.
    In 2010 the experts could replicate marks on the shroud employing highly advanced UV techniques that weren’t available 2,000 years ago or during the medieval period.

    A 1980s study claims the image was “faked” on the cloth sometimes between 1260 and 1390, but researchers said the report was based on checking material from a patch likely used to repair the cloth after being damaged by fire.

    The researcher wished to unveil the breach in their findings.
    Vatican Insider writes:
    “This inability to repeat (and therefore falsify) the image on the Shroud makes it impossible to formulate a reliable hypothesis on how the impression was made.”

    However, professor Manuela Marinelli considers that the Shroud is at least 95 percent authentic. “None can provide a 100 percent certainty 2,000 years after it had been found.”

    Question of questions!!! Despite the number of research studies, Vatican Insider comes up with one of the most puzzling question ever:
    “Irrespective of the age the Shroud, either being medieval (1260 – 1390) as proved by the controversial dating by radiocarbon, or older as demonstrated by other investigations, and disregarding the actual importance of controversial historical documents on the existence of the Shroud in the years preceding 1260, the most important question, the “question of questions” sill stands: how did that body image showed up on the Shroud?

  • Europe, World on alert! A Dutch university laboratory created a deadly H5N1 strain of bird flu

    A highly contagious strain of avian influenza, created in a Dutch laboratory and able to infect and kill millions of people around the world put on alert the authorities after the European researchers wish to reveal the details of how they managed to do it, reports The Independent.

    The laboratory has indicated its intention to publish their results, sparking fears that the new virus could attract the interest of terrorists.

    U.S. administration fears that the deadly strain of bird flu could leak to the terrorists who might use it as a biological weapon of mass destruction.

    Some scientists believe that this research should not have been conducted in a university laboratory, but a military facility.

    For the first time, researchers were able to carry out a mutation of the H5N1 strain of avian influenza virus such that can be spread easily through the air by coughing and sneezing.

Dutch scientists have performed​ this controversial research to demonstrate how easy it is to achieve a genetic mutation of the H5N1 strain to become highly contagious human flu.

    They believe that new knowledge will help develop new vaccines and drugs.

    The H5N1 mutation research was conducted by a team of Dutch scientists, led by Ron Fouchier at the Erasmus Medical Center in Rotterdam, where the mutant virus is kept locked in the basement of a building, but without armed guards.

    The Dutch virologist Ron Fouchier began the scietific career as an expert in HIV-1. He obtained his PhD title at the University of Amsterdam in 1995. Following studies at the University of Pennsylvania School of Medicine, he shifted to a new focus in virology at Erasmus Medical Centre in Rotterdam, studying the molecular biology of the influenza A virus.

    During Malta conference last September, Fouchier said of his research as something that was “really, really stupid,” but ultimately helpful for the discovery of new vaccines.
