    Evolutionary Leaps ^ | June 2010 | Robert Felix & video by Dr. Gregory Ryskin, Professor
    Jun 2010 - The Permian-Triassic Extinction Event, the largest extinction in history, could have been caused by huge, worldwide methane explosions, says Dr. Gregory Ryskin, Professor of Chemical Engineering at Northwestern University Could such explosions have created the Carolina Bays? (More than two million huge holes were gouged into the ground about 12,000 years ago at the Gothenburg magnetic reversal. Some of the holes - which are still there - are bigger than nearby cities. Those holes are now collectively known as the Carolina Bays.) During the Great Permian Extinction, when up to 95% of all species went extinct, Dr....

    The worst-case scenario of the consequences of global warming - mass extinctions - appears to be a reality for lizards, according to a new report in Science. The authors found that 12 percent of local populations of lizards have already disappeared from hundreds of sites in Mexico. Furthermore, within the next 70 years, the authors predict that 1 in 5 lizard species will no longer exist anywhere on the planet, all the result of rising global temperatures. Although a growing amount of data is showing the impact of climate change on species, these lizard extinctions were somewhat surprising, said Jack...

    The Anglican Church in Canada – once as powerful in the nation's secular life as it was in its soul – may be only a generation away from extinction, says a just-published assessment of the church's future. The report, prepared for the Anglican Diocese of British Columbia, calls Canada a post-Christian society in which Anglicanism is declining faster than any other denomination. It says the church has been “moved to the far margins of public life.” According to the report, the diocese – “like most across Canada” – is in crisis. The report repeats, without qualification or question, the results...
  • Tasmanian Devil Facial Cancer Origins 'Identified'

    Researchers believe they have identified the source of fatal tumours that threaten to wipe out the wild population of Tasmanian devils. Writing in Science, an international team of scientists suggest cells that protect nerves are the likely origin of devil facial tumour disease (DFTD). The disease is a transmissible cancer that is spread by physical contact, and quickly kills the animals. DFTD has caused the devil population to collapse by 60% in the past decade. "To look more closely at the tumours' origin, we sequenced the genes that are expressed in this devil cancer and compared them with other genes...

  • Findings on Origin of a Cancer in Tasmanian Devils (Davils hurtling toward extinction)

    The Tasmanian devil, the spaniel-size marsupial found on the Australian island of Tasmania, has been hurtling toward extinction in recent years, the victim of a bizarre and mysterious facial cancer that spreads like a plague. Now Australian scientists say they have discovered how the cancer originated. The finding, being reported Friday in the journal Science, sheds light on how cancer cells can sometimes liberate themselves from the hosts where they first emerged. On a more practical level, it also opens the door to devising vaccines that could save the Tasmanian devils. “It’s a great paper,” said Katherine Belov, a geneticist...

    Climate change threatens the survival of dozens of animal species from the emperor penguin to koalas, according to a report released Monday at the UN climate summit. Rising sea levels, ocean acidification and shrinking polar ice are taking a heavy toll on species already struggling to cope with pollution and shrinking habitats, said the study from the International Union for the Conservation of Nature (IUCN), an intergovernmental group. "Humans are not the only ones whose fate is at stake here in Copenhagen -- some of our favourite species are also taking the fall for our CO2 emissions," said Wendy Foden,...

    Stephen Hawking believes that one of the major factors in the possible scarcity of intelligent life in our galaxy is the high probability of an asteroid or comet colliding with inhabited planets. We have observed, Hawking points out in Life in the Universe, the collision of a comet, Schumacher-Levi, with Jupiter (below), which produced a series of enormous fireballs, plumes many thousands of kilometers high, hot "bubbles" of gas in the atmosphere, and large dark "scars" on the atmosphere which had lifetimes on the order of weeks. It is thought the collision of a rather smaller body with the Earth,...

    Comet strikes are an unlikely cause of past mass extinctions on Earth, according to computer simulations. Scientists used the simulations to model the paths of long-period comets, to determine the likelihood of these "dirty snowballs" striking our planet. The University of Washington, Seattle, research appears in Science journal. How many mass extinctions in Earth's history were caused by these icy bodies crashing into our planet has been a subject of considerable debate. Many scientists agree that an asteroid strike 65 million years ago wiped out the dinosaurs. But there is uncertainty about how many other such events were triggered by...

    NY- The Internet is by far the most popular source of information and the preferred choice for news ahead of television, newspapers and radio, according to a new poll in the U.S. But just a small fraction of U.S. adults considered social Web sites such as Facebook and MySpace as a good source of news and even fewer would opt for Twitter. More than half of the people questioned in the Zogby Interactive survey said they would select the Internet if they had to choose only one source of news, followed by 21% for television and 10% for both newspapers...

    A brilliant burst of gamma rays may have caused a mass extinction event on Earth 440 million years ago—and a similar celestial catastrophe could happen again, according to a new study. Most gamma-ray bursts are thought to be streams of high-energy radiation produced when the core of a very massive star collapses. Such a disaster may have been responsible for the mass die-off of 70 percent of the marine creatures that thrived during the Ordovician period (488 to 443 million years ago), suggests study leader Brian Thomas, an astrophysicist at Washburn University in Kansas. The simulation also shows that a...

    Feb. 4, 2009 -- An ancient killer is hiding in the remote forests of Siberia. Walled off from western eyes during the Soviet era and forgotten among the endless expanse of wilderness, scientists are starting to uncover the remnants of a supervolcano that rained Hell on Earth 250 million years ago and killed 90 percent of all life. Researchers have known about the volcano -- the Siberian Traps, for years. And they've speculated that the volcanic rocks, which cover an area about the size of Alaska, played a role in runaway global warming that led to the end -- Permian...

    Arctic find challenges the idea that the massive reptiles declined slowly. A new fossil find suggests the dinosaurs may have died out quickly.Ablestock / Alamy Fossils uncovered recently in the Arctic support the idea that dinosaurs died off rapidly — perhaps as the result of a massive meteor hitting Earth. The finding contravenes the idea that dinosaurs were already declining by this time.Geological evidence indicates that an impact occurred near the Yucatán Peninsula at the end of the Cretaceous 66 million years ago. But whether the event created an all-out apocalypse that wiped out the dinosaurs is still a matter...

    With the increased seismic activity in the Yellowstone Caldera, it is likely that there is some increased interest in in the geology of the area. Here are some resources that should be of interest. First, we have a fairly recent peer reviewed publication on the "Super Volcano" known as Yellowstone, including some discussion of just what a "Super Volcano" is. The largest scale of volcanic eruptions, the so-called super-eruptions, can destroy all living beings and infrastructure over tens of thousands of square kilometres, can disrupt agriculture over millions of square kilometres and can alter global climate for years or decades....
