Lungs of Europe Burning

Scientists are concerned about fire and logging destroying the Siberian taiga, also known as the "lungs of Europe." The Siberian taigi contains half of the planet's evergreen trees and 1/5 of the world's forested area. National Geographic has a description and photograph of the Siberian taiga here. The Independent reports that large swathes are the forest are being destroyed by logging and fires caused by global warming.
Twenty years ago forest fires destroyed about two million hectares of Siberian forests - the loss of an area the size of Wales. Last year 22 million hectares - about half the size of France - were lost to fire. Russian forestry scientists said they were bracing themselves for this year's fire season, which starts in late June.

Siberia's largest forest, the taiga, accounts for one fifth of the world's total forested land and contains half of the planet's evergreen forest. Yet in the space of a couple of decades this seemingly unlimited expanse of trees has suffered an unprecedented tenfold increase in the rate of deforestation caused by fire.

  • First Ever Heat Advisory for Seattle Area

    Hot weather in the Seattle metropolitan area has boosted temperature 20+ degrees above average. Temperatures are expected to reach the upper 80s to low 90s in the normally cool climate that is perfect for coffee consumption. The Associated Press reported that Thursday's high temperature of 89 degrees at Seattle-Tacoma International Airport broke a 58-year-old record. The National Weather Service issued the first-ever heat advisory for the area:
    Temperatures will climb into the upper 80s and lower 90s today in parts of the Everett-Seattle-Tacoma urban corridor...more than 20 degrees above normal for late may. Excessive physical activity in heat this intense can be dangerous. The elderly...very young... sick...and persons with heart conditions are most at risk.
    More on hot temperature in Seattle and Washington can be found here on the NWS website.

    Marburg Outbreak Continues in Angola

    The marburg outbreak that has struck with surprising tenacity in Angola has now killed 315 people. The New York Times reports that new cases continue to emerge.
    The epidemic in Angola, thought to have begun weeks or months before it was recognized, is the largest on record. As of yesterday, there was a total of 376 suspected or confirmed cases in Uíge, including 315 deaths. The disease is spread by contact with body fluids like blood, saliva or urine, though people do not transmit the virus until they become ill. Those who recover can still transmit the virus sexually for about three months.

    Ms. Bhatiasevi said that because the virus had also been found in breast milk, infected mothers were being advised not to breast-feed. Healthy mothers of infected children were also being advised not to breast-feed, she said, lest the mothers become infected as well.

    Marburg, a close relative of the Ebola virus, causes a hemorrhagic fever that is often fatal within a week. The incubation period is three to nine days. There is no cure, and no vaccine.
    The Times article also says that cases are being reported in areas where there were no cases before and that health workers in the area say the outbreak is still not over. This outbreak surpassed previous marburg outbreaks as the worst ever several weeks ago.

    Huge Planet Discovered With Microlensing

    The BBC reports that a planet three times as big as Jupiter and located 15,000 light-years from Earth has been discovered using a microlensing technique. The BBC also said that two amateur astronmers in New Zealand discovered the planet using "backyard" telescopes and the microlensing technique:
    Microlensing occurs when a massive object in space, like a star, crosses in front of another star shining in the background.

    The near object's gravity bends the light rays from the more distant object and magnifies them like a lens. Here on Earth, we see the star get brighter as the lens crosses in front, and then fade as the lens moves away.

    Scientists Create Tailor Made Stem Cells

    The big news in science health news this week was a report from South Korea that a group of scientists have found a way to create stem cells that match the genes of the patients. Because stem cells can be used to grow cells for many different tissues, organs, bones, etc. this could be an incredible breakthrough if it turns out to be true. Scientists will try and reproduce the results found by the South Korean scientists in other labs around the world. The BBC has an article about the discovery. This raises big questions for medical research here in the United States? With the possibility of enormous health benefits why is the U.S. government not pouring money into stem cell research? The answer is that President Bush and some far-right religious groups claim the procedure is unethical because it uses stem cells from cloned embryos. However, a similar procedure is used with in vitro fertilization and you don't hear these same politicians arguing against this procedure. Unfortunately, President Bush has already announced that he will veto any bill that comes his way that increases embryonic stem cell funding or lessens current restrictions. The Media Cynic has more about Bush's veto threat.

    2004 Sumatra Quake Vibrated Entire Planet

    Last year's massive earthquake near Sumatra which generated the killer tsunami was also the longest earthquake ever recorded. CNN reports that the quake released energy equivalent to a 100 gigaton bomb. The magnitude of the quake has also been increased from the original estimate of 9.0 to somewhere between 9.1 and 9.3.
    "Normally, a small earthquake might last less than a second; a moderate sized earthquake might last a few seconds. This earthquake lasted between 500 and 600 seconds," said Charles Ammon, associate professor of geosciences at Penn State University.

    The quake released an amount of energy equal to a 100 gigaton bomb, according to Roger Bilham, professor of geological sciences at the University of Colorado.
    The article also says that the earthquake was picked up all over the world -- everywhere that scientists had instruments they were able to detect the massive earthquake.

    WHO Confirms Ebola in Congo

    The World Health Organization (WHO) has confirmed that Ebola has caused the death of nine people in Congo. There have been 11 cases so far. An outbreak of ebola in Congo in 2003 killed 150 people. From a ProMed report:
    "The results (of laboratory tests) came in yesterday ... It is indeed a case of Ebola," said Adamou Yada, WHO's representative in Congo, which has faced serious outbreaks of the disease in the past. Nearly 150 people died in 2003.

    "Since the beginning (of the outbreak), we have registered 11 cases, including 9 deaths," Yada said in the capital Brazzaville. The latest outbreak is in the forested Cuvette-Ouest region, near the border with Gabon, where the 2003 outbreak struck.

    Get Ready for Another Bad Hurricane Season

    Hurricane season begins on June 1st. That doesn't mean a hurricane can't or won't form before that date. It is just the date the National Hurricane Center (NHC) uses to begin issuing regular tropical weather advisories and discussions. The NHC will issue advisories if a tropical disturbance forms before June 1st. The most active period for hurricanes is usually during August, September and October with the peak falling during the month of September. Last year's season was unusual with four hurricanes hitting Florida. The Associated Press reports on this year's forecast:
    Conrad C. Lautenbacher Jr., head of the National Oceanic and Atmospheric Administration, predicted 12 to 15 tropical storms, seven to nine of them becoming hurricanes, and three to five of those major hurricanes, with winds of at least 111 mph.

    "We can't predict this far in advance how many will strike land," he said. But given the active season, "be prepared for two or three of these to make landfall."
    Here is a link to the full outlook from the NOAA.

    NOAA Issues Space Weather Warning

    Forecasters at the NOAA Space Environment Center in Boulder, Colo., observed a geomagnetic storm on Sunday, May 15, which they classified as an extreme event, measuring G-5—the highest level on the NOAA Space Weather Scales. As a result NOAA has issued a Space Weather Warning. In the right-hand corner is an image of the storm from the SOHO satellite. A larger version of the image is available here. Slashdot has an ongoing discussion about this story. Here is part of NOAA's Weather Warning announcement:
    "This event registered a 9 on the K-Index, which measures the maximum deviation of the Earth's magnetic field in a given three-hour period," said Gayle Nelson, lead operations specialist at NOAA Space Environment Center. "The scale ranges from 0 to 9, with 9 being the highest. This was a significant event."

    Possible impacts from such a geomagnetic storm include widespread power system voltage control problems; some grid systems may experience complete collapse or blackouts. Transformers may experience damage. Spacecraft operations may experience extensive surface charging; problems with orientation; uplink/downlink and tracking satellites. Satellite navigation may be degraded for days, and low-frequency radio navigation can be out for hours. Reports received by the NOAA Space Environment Center indicate that such impacts have been observed in the United States.

    Scientists Create Robots That Self-replicate

    A group of scientists at the Cornell Computational Synthesis Lab have invented a way for robots to self-replicate. The scientists say an advanced form of the technology might allow robots to repair themselves which could be very useful on a robot-only space mission where there are no humans to repair damaged robots.

    Pleasant Morning Buzz points out a frightening science fiction scenario involving robot replication (the Replicators from StarGate). A Faq on the project website attempts to provide an answer to the question: Could the robots proliferate out of control? The scientists say:
    These robots were programmed to stop after two generations, because we wanted to show just a proof of concept. Also, they cannot reproduce without a supply of power and more cubes provided at the right place and at the right time, so they are fairly constrained and under control. So there is no danger they will "take over the world". Other forms of artificial self-replication can be more concerning - computer viruses and genetically modified crops, for example, are less controllable. Ray Kurzweil has an interesting discussion on the Ethics and concerns of self-replication technologies.

    Orange UFOs Spotted Over Melbourne

    Orange UFOs have been spotted over Melbourne. And police said Melbourne Airport reported nothing on the radar during the time many citizens of the Australian city reported the orange lights or objects. The Herald Sun has a report on the strange incident.
    Another friend, Stuart Wilson, 24, managed to take video footage of the lights.

    The shaky video shows a dozen pricks of light forming shapes such as diamonds, lines, characters and what looks like the Southern Cross.

    The lights were visible for 10 minutes before flying in different directions and vanishing, Mr Wilson said.

    "It's possible aliens are driving them, but until I see one I'm not going to be convinced," he said. "This is pretty close, but I didn't see any little green men."

    But Mr Webster didn't need convincing.

    "I was never into sci-fi but now I'm going to do my homework on UFOs," he said.

    What King Tut May Have Looked Like

    Forensic scientists, working in three seperate teams, have reconstructed King Tutankhamun's face using photos from CT scans. The BBC reports that the images are simliar to King Tut's mask and images found on artwork when his tomb was discovered in 1922:
    The models bear a striking resemblance to the mask which covered the mummified face of King Tutankhamun when his remains were found by archaeologist Howard Carter in 1922 and other ancient portraits.

    "The shape of the face and skull are remarkably similar to a famous image of Tutankhamun as a child where he was shown as the sun god at dawn rising from a lotus blossom," said Zahi Hawass, Secretary-General of the Egypt's Supreme Council of Antiquities.
    A National Geographic article explains the reconstruction process in greater detail.

    USGS Calls for Volcano Early Warning System

    The U.S. Geological Survey (USGS) has released the first ever comprehensive and systematic review of the 169 U.S. volcanoes and established a framework for a National Volcano Early Warning System (NVEWS) which calls for a 24-hour seven-day-a-week Volcano Watch Office and enhanced instrumentation and monitoring at targeted volcanoes. The Yellowstone caldera is one of those listed as high risk for an explosion by the USGS according to an Associated Press story on the report:
    Yellowstone ranks 21st most dangerous of the 169 volcano centers in the United States, according to the Geological Survey's first-ever comprehensive review of the nation's volcanoes.

    Kilauea in Hawaii received the highest overall threat score followed by Mount St. Helens and Mount Rainier in Washington, Mount Hood in Oregon and Mount Shasta in California. Kilauea has been erupting since 1983. Mount St. Helens, which erupted catastrophically in 1980, began venting again in 2004.
    According to the USGS report, since 1980, 45 eruptions and 15 cases of notable volcanic unrest have occurred at 33 U.S. volcanoes. About half of the most threatening U.S. volcanoes are monitored at a basic level and a few are well monitored with a suite of modern instruments. However, the report cautions, monitoring capabilities at many hazardous volcanoes are sparse or antiquated, and some hazardous volcanoes have no ground-based monitoring whatsoever. This poses a threat to people on the ground and in the air. Flying into an ash cloud can cripple a jet aircraft in flight. Tens of thousands of people fly over U.S. volcanic regions every day.

    The Multi-ton Megasquids are Coming

    Yes, humans are doomed and the megasquids are destined to take our place -- if Dougal Dixon and John Adams authors of The Future is Wild are correct. But don't worry it won't happen anytime soon. The authors believe there might not only be gaint land squids but huge rodents and flying bumblebeetles as well. A recent MSNBC.com article discusses this possible future and several others as well -- even ones where humans actually survive thanks to genetic engineering. Here is how MSNBC describes the vision from The Future is Wild:
    In their vision, humans become extinct in an Ice Age 5 million years from now. "Shagrats," or giant rodents, and "gannet whales," large aquatic birds, have evolved during this stretch of time.

    The Ice Age melts away 100 million years later, marking the beginning of the end of large mammals and giving rise to creatures like the "ocean phantom," a jellyfish the size of a truck; the "swampus," a relative of the octopus that emerges from swamps to feed; and the "toraton," a reptile bigger than dinosaurs.

    In 200 million years, evolution brings bizarre animals like "flish," birds that evolved from fish; "bumblebeetles," beetles that fly; and "megasquid," multi-ton, land-based squid creatures.

    "Squibbons," a hybrid squid-gibbon ape, live in trees, eat plants as well as flish and "represent the pinnacle of intelligent life on Earth," according to Dixon and Adams' vision.

    Blog Chases Tornadoes

    WeatherBug has a blog called StormChase 2005 that has been tracking the WeatherBug team's efforts to chase a tornado. Their hard work was rewarded on May 6th when they spotted a funnel emerging from a wall cloud:
    Today was a great day! We tracked a storm from its beginnings as a small cumulus cloud crossing the dryline, to its development into a full mesoscale system complete with two funnels that lowered several hundred feet out of a wall cloud before they dissipated back up into the cloud. Fortunately for the farmers and residents of Dundy County, no tornadoes touched down. It was a thrill to behold. Megan's Boston accent finally came out as she kept repeating "This is wicked awesome!" We captured great video and photos. A few are included below and some in my photo album that you can view at right. Take a look!

    Marburg Outbreak Ongoing

    The Marburg outbreak in Angola continues to sicken and kill local citizens. Over 277 people have died so far. The WHO reports that new vehicles and resources continue to be applied to stop the outbreak. During this outbreak of Marburg the disease has killed about 90% of those who have fallen ill. From WHO's latest report:
    As of 3 May, the Ministry of Health in Angola has reported 308 cases of Marburg haemorrhagic fever. Of these cases, 277 were fatal. In Uige Province, which remains the epicentre of the outbreak, 297 cases, of which 266 have been fatal, were reported. The large increase in the number of reported cases for Uige is the result of retrospective investigation and entry into the database of cases that occurred previously. However, new confirmed cases and deaths continue to be reported in Uige.

    666 Not So Bad After All

    An acient 1,500-year-old Greek papyrus has been found that contains a Book of Revelation passage that shows 666 is not the "number of the beast." The correct number according to the text is 616. This papryus, which was part of the Oxyrhynchus discovery, predates all other existing Revelations documents. The National Post has more on the story:
    The tiny fragment of 1,500-year-old papyrus is written in Greek, the original language of the New Testament, and contains a key passage from the Book of Revelation.

    Where more conventional versions of the Bible give 666 as the "number of the beast," or the sign of the anti-Christ whose coming is predicted in the book's apocalyptic verses, the older version uses the Greek letters signifying 616.

    "This is very early confirmation of that number, earlier than any other text we've found of that passage," Dr. Aitken said. "It's probably about 100 years before any other version."

    Animals Grow Human Organs for Science

    Scientist are growing human tissue and organ inside of animals for study and the possibility of creating donor parts that can be harvested from the animals. MSNBC.com reports that just outside of Reno, Nevada a farm contains a "flock of about 50 smelly sheep, many of them possessing partially human livers, hearts, brains and other organs." The research is legal and could have huge health benefits but some are concerned that growing human parts inside mice, pigs, sheep and other animals is gong too far.
    But the biological co-mingling of animal and human is now evolving into even more exotic and unsettling mixes of species, evoking the Greek myth of the monstrous chimera, which was part lion, part goat and part serpent.

    In the past two years, scientists have created pigs with human blood, fused rabbit eggs with human DNA and injected human stem cells to make paralyzed mice walk.

    Particularly worrisome to some scientists are the nightmare scenarios that could arise from the mixing of brain cells: What if a human mind somehow got trapped inside a sheep's head?
    One of the problems with the research so far is that the organs grown inside the sheep and other animals tend to mix with the animal's own cells which would cause problems during transplanting such as rejection -- or worse giving the recipient a disease the animal had.

    Beautiful Mummy Found

    A stunning 2,300 year-old mummy has been found in Egypt's Saqqara Pyramids. The AP reports that the mummy is from the 30th pharaonic dynasty and is wrapped with spectacular colors and artwork.
    The mummy, found two months ago, was covered from head to toe in brightly colored cartonage burial material depicting a range of graphic scenes, including the Goddess Maat of balance and truth who was shown with outstretched arms that took the shape of feathered wings.

    Also shown were the four children of the falcon-headed god, Horus, and the rituals and processes to mummify the person, who Hawass believed must have been wealthy considering his burial location and fine gold used for the mummy's mask.

    Attack of the Flying Squids

    Scientists are watching for flying jumbo giant squids off the coast of British Columbia. Last year the Royal B.C. Museum obtained 11 Humboldt squid specimens -- which previously had not been seen that far North. The Globe and Mail reports that fishermen fear the creatures and for good reason:
    Some descriptions from witnesses sound like the plot to a horror movie -- water roiling with tentacles; otherworldly creatures suddenly launching into the air from beneath the surface; nightfall bringing to the surface vicious predators that slip back into the depths at daybreak, like vampires of the sea.

    A Humboldt squid can grow to the size and weight of a hockey player. So, imagine Todd Bertuzzi with bulging eyes, eight arms, two tentacles, three hearts, a beak for a mouth, a brain wrapped around his esophagus and gullet with a willingness -- nay, eagerness -- to dine on his own kind every other meal, and you get a sense of how the squid has earned such a fearsome reputation.

    Mexican fishermen call the creature el diablo rojo -- the red devil.
    Dave Barry's Blog offers a humorous take on this story.
