The Asp: a Toxic Caterpillar
The Asp, also known as a Puss Moth Caterpillar, is a dangerous pest that many people are unaware of since caterpillars and moths are typically seen as harmless. The Asp can be found in Texas and other southern states. The UT Houston Medical School offers a webpage with more information about these unusual caterpillars including an explanation of why they are a serious health risk.
Puss moth caterpillars can pose a genuine health hazard. Intense, throbbing pain develops immediately or within five minutes of contact with the caterpillar. Stings on the arm may also result in pain in the axillary (armpit) region. Erythematous (blood-colored) spots may appear at the site of the sting. Other symptoms can include headaches, nausea, vomiting, intense abdominal distress, lymphadenopathy, lymphadenitis, and sometimes shock or respiratory stress. Pain usually subsides within an hour and spots disappear in a day or so -- however, with a larger dose of the venom, it is not uncommon for the symptoms to last up to 5 days.
More information can be found on this website which refers to the asp as the most toxic caterpillar in the U.S. An article on PubMed explains more about the health risk from Asps:
The most frequently reported caterpillar envenomation in Central Texas is by the puss caterpillar or "asp," Megalopyge opercularis. This caterpillar is described by patients and physicians as inflicting intense radiating pain. The intensity of symptoms may be underestimated leading to undertreatment. Adequate treatment protocols have been lacking and those in use are not very successful.

Tropical Storm Beta Forms in Caribbean
Tropical Storm Beta, the 23rd named storm of this extraordinarily busy year, has formed in the Caribbean. The current forecast from the National Hurricane Center has Beta becoming a Category 2 Hurricane and making landfall on the coast of Nicaragua. A couple computer models show Beta as a threat to Florida but the NHC does not think this scenario is likely.
IT SHOULD BE NOTED THAT TWO
MODELS WHICH BRING BETA NORTHWARD TOWARD CUBA AND FLORIDA...LBAR
AND THE CANADIAN...HAVE SHOWN A NORTHWARD BIAS IN PREVIOUS SIMILAR
SITUATIONS. THEREFORE...WHILE NOT BEING RULED OUT AS POSSIBILITIES
THEY ARE BEING GIVEN LITTLE WEIGHT AT THIS TIME.
The next named storm in this record breaking season will be named Gamma. If more storm develop after Gamma they will be named Delta, Epsilon, Zeta and onward deeper into the Greek Alphabet.

Wilma Slightly Amplifies Noreaster
MSNBC.com is reporting that a Nor'easter has formed and is being amplified by Hurricane Wilma, which is located very far offshore. The NWS said the storm is a strong storm even without Wilma's help.
An early nor'easter reinforced by distant Hurricane Wilma on Tuesday pounded beaches with 20-foot waves, knocked out power to thousands of people and spread rain across the Northeast, where many residents were still cleaning up from flooding earlier in the month.
The low pressure system has intensified with added moisture from Wilma.
Twenty-foot waves eroded New Jersey beaches. Dozens of flights were canceled at Boston's Logan Airport and gusts to 70 mph were reported on Cape Cod.
The storm was drawing moisture from the remnants of Hurricane Wilma, which was passing far offshore after battering Florida a day earlier.
"It's getting some energy from Wilma, but it's its own separate system," said Alan Dunham, a meteorologist with the National Weather Service in Taunton. The nor'easter is "going to be a good storm in it's own right."
Despite the strong winds and rain the Northeast is actually very lucky compared to how bad it would have been if Wilma had hugged the east coast on its way north. Fortunately Wilma is 600 miles to the east and is moving north rapidly at a speed of over 50 mph.

Wilma Hits South Florida as Cat 3
Hurricane Wilma strengthened over night to sustained winds of 125 mph to hit Southwestern Florida as a Category 3 hurricane. After moving across the everglades the storm only weakened slightly and still carried sustained winds of 110 mph into major cities like Miami, Ft. Lauderdale and West Palm Beach. There have been early reports of serious flooding in the Florida Keys and there will be lots of wind damage across Southern Florida. Miami.com and the Sun-Sentinel.com websites have damage reports. Our BloggersBlog.com website lists lots more Wilma blog and news resources. Wilma is not forecast to become a dangerous northeaster but the Northeast will need to keep a close eye on Wilma just in case.

Tropical Storm Alpha Forms
The National Hurricane Center reports that Tropical Storm Alpha has formed to the southeast of Hispanola making 2005 the most active hurricane season on record.
AT 18Z...A SHIP REPORT FROM
C6FN4 HAD A 22 KNOT SOUTHWEST WIND ABOUT 30 NM SOUTHEAST OF THE
CENTER WITH A 1007 MB PRESSURE. BASED UPON THE ABOVE INFORMATION
THE CYCLONE HAS BEEN UPGRADED TO TROPICAL STORM ALPHA. ALPHA IS THE
TWENTY-SECOND NAMED STORM THIS SEASON AND OVERALL MAKES THE 2005
HURRICANE SEASON THE MOST ACTIVE ON RECORD.
The NHC forecasts Alpha to slowly strengthen in then make landfall in southern Hispanola. The storm is supposed to move to the north and northeast after Hispanola. Alpha is not expected to threaten the U.S.

Wilma Slowly Exits Yucatan
Wilma is just starting to emerge in the Gulf of Mexico after spending several hours inland over the Yucatan Peninsula. The damage in Cancun and Cozumel could be catastrophic with the duration and strength of the winds experience there. An MSNBC.com article has some initial damage reports as well as reports of looting in the mostly abadoned tourist destinations. Unfortunately for Florida residents the structure of Wilma still looks pretty solid. Wilma is still a Category 2 hurricane with sustained winds of 100mph and the latest forecast has her strengthening back to at least a Cat 3.
MAXIMUM SUSTAINED WINDS ARE NEAR 100 MPH...160 KM/HR...WITH HIGHER
GUSTS. WILMA IS A CATEGORY TWO HURRICANE ON THE SAFFIR-SIMPSON
SCALE. SOME STRENGTHENING IS FORECAST DURING THE NEXT 24
HOURS...AND WILMA COULD REGAIN CATEGORY THREE STATUS DURING THE
NEXT 24 HOURS.
Wilma is also a large storm with hurricane winds extending out 85 miles from the center and tropical storm force winds extending 200 miles from the center. A large area of Florida will be impacted with strong winds regardless of where in Florida she makes landfall. Hurricane watches are already up for the Keys as well as South and Central Florida counties. Maps showing the advisories can be found here and here. It still unclear what impact, if any, Wilma will have on the Northeast coast.

Wilma Weakens Slightly and Slows Down
Hurricane Wilma has weakened slightly and is slowing down. Wilma is now a very strong Category 4 hurricane. Wilma's winds have dropped to 145 mph -- this is still an extremely dangerous and destructive hurricane. The forecast path for Wilma from the NHC has changed slightly and there is now a greater chance Wilma will make a landfall on the Yucatan Peninsula. The forecast path has not changed for Florida and a second landfall is still forecast for Florida. Because of the slower pace of Wilma this landfall has been delayed and will take place on Sunday instead of Saturday. The NHC forecast still has Wilma making landfall in Florida as a major hurricane -- Category 3. However, if Wilma spends a long time over the Yucatan it could weaken considerably. Dr. Jeff Masters explains:
Finally, by Saturday, strong westerly winds will build in behind the trough and carry Wilma rapidly northeastward across South Florida or the waters between Florida and Cuba. The absolutely critical thing is -- where will Wilma stall out? The GFDL model believes Wilma will push inland over the tip of the Yucatan, and spend two days overland, and weaken to a tropical storm. The UKMET model believes Wilma will stall in the Yucatan Channel, and not lose much strength. The other models have modest variations on these two themes. The difference in postions is only 100 miles or so. This is impossible to reliably forecast even 12 hours in advance, given the weak steering currents that are likely to exist Friday. Will will just have to wait and see what happens. Very small changes in storm position will cause huge changes in Wilma's intensity.
The risk to the Northeast and New England still exists but it will be a while before we know whether Wilma stays far offshore or makes a severe impact on the Northeast.

Hurricane Wilma Most Intense Ever in Atlantic Basin
Wilma is now the most intense hurricane ever in the Atlantic basin with a minimum central pressure of 882 millibars. Winds are sustained at 175 mph. The National Hurricane Center continues to forecast a hit on South Florida and some evacuations have already started in the Florida Keys. Skeetobite Weather has some good graphics that show the forecasted path of Wilma. Some of the computer models are showing a threat to the New England region but so far the NHC has not adjusted their 5 day path to the left. We would not want to see another Long Island Express scenario. Our Hurricane Wilma Section on BloggersBlog.com will continue to provide blog coverage as well as links to blogs, graphics and news resources.

Wilma Now a Cat 5 With 175 Mph Winds
Hurricane Wilma has been upgraded by the NHC to an incredibly powerful Category 5 hurricane with sustained winds of 175mph. The minimum pressure has dropped to 892 mb making Wilma the strongest storm of 2005 and tying the record for the 2nd most intense hurricane every recorded in the Atlantic. The all-time lowest was Gilbert with a minimum pressure of 888 mb. The National Hurricane Center relaesed a special update after receiving new data from a hurricane hunter aircraft.
DATA FROM A RECONNAISSANCE AIRCRAFT INDICATE THAT HURRICANE WILMA
HAS BECOME AN EXTREMELY DANGEROUS CATEGORY FIVE HURRICANE ON THE
SAFFIR-SIMPSON HURRICANE SCALE. THE RECONNAISSANCE PLANE MEASURED
175 MPH WINDS AND ESTIMATED A MINIMUM PRESSURE OF 892 MB. THIS IS
THE LOWEST PRESSURE OBSERVED IN 2005 AND IS EQUIVALENT TO THE
MINIMUM PRESSURE OF THE 1935 LABOR DAY HURRICANE IN THE FLORIDA
KEYS.

Wilma Bombs Out. Strengthens to Strong Category Four.
Hurricane Wilma has strengthened incredibly rapily today and has become a straong Category Four Hurricane with sustained winds of 150 mph. Wilma is very close to a Category Five and could become one tomorrow according to the National Hurricane Center. Wilma has a very low minimum central pressure of 901 mb which puts it in the same ballpark as the deadly hurricanes Rita and Katrina. Wilma's pressure is actually lower than Katrina's lowest minimum central pressure of 902 mb.
AN AIR FORCE PLANE MEASURED MAXIMUM SUSTAINED WINDS OF NEAR 150
MPH...240 KM/HR...WITH HIGHER GUSTS. WILMA IS AN EXTREMELY
DANGEROUS CATEGORY FOUR HURRICANE ON THE SAFFIR-SIMPSON SCALE. THE
HURRICANE COULD BECOME A CATEGORY FIVE HURRICANE TODAY.
LATEST MINIMUM CENTRAL PRESSURE JUST REPORTED BY AN AIR FORCE
RECONNAISSANCE PLANE WAS IS 901 MB...26.61 INCHES.
It is unbelievable to see so many incredibly powerful hurricanes in one season. The NHC is describing the eye of Hurricane Wilma as a "pinhole eye." Unfortunately, for Floridians the forecast path still shows Wilma targeting the Florida Peninsula with South Florida as the highest probable landfall area. If Wilma retains most of its strength and moves rapidly over Florida as expected then some inland Florida counties and east coast Florida counties may also experience strong winds. More Hurricane Wilma blogs and news coverage can be found here.

Hurricane Wilma Threatens Florida and East Coast
Wilma is now a Category 1 Hurricane with sustained winds of
80 mph. The National Hurricane Center is forecasting Wilma to strengthen to a Cat 3 Hurricane and eventually make landfall somewhere on the Florida Peninsula this weekend with South Florida being the most likely target. After making landfall in Florida, Wilma could move very rapidly up the east coast possibly battering New England with heavy winds and rain. The Eastern US Weather Forum is currently discussing this possiblity. The Philadelphia Weather blog also says there is the potential for a big east coast storm with Wilma. The Sun-Sentinel offers good coverage of the storm for Floridians. More blogs and news resources covering Wilma can be found on the Hurricane Wilma section of our BloggersBlog.com site.

Tropical Storm Wilma Forms in the Caribbean
The National Hurricane Center reports that Tropical Storm Wilma has formed in the Caribbean. This ties the 1933 record for the most named storms ever at 21. Wilma is currently forecast to strengthen to a hurricane and make a first landfall on the Yucatan Peninsula. Then Wilma is forecast to enter the Gulf of Mexico, so there is a potential U.S. threat from Wilma. Florida residents should keep an eye on Wilma since cold fronts often pick up tropical systems this time of year and move them north and northeast. Dr. Jeff Masters also blogs that a Florida landfall is a likely possibility. He also points out that Hurricane Stan, which caused devastation in Guatemala, is now the 30th deadliest hurricane. Over 400 deaths occurred from a massive mudslide created by Stan's heavy rains. The next storm names will come from the Greek alphabet: Alpha, Beta, etc.

Bird Flu Confirmed in Romania
The BBC reports that one day after being confirmed in Turkey the deadly H5N1 strain of avian flu that has killed over sixty people has now been confirmed in Romania.
The test result confirms that the lethal variant of the virus has arrived on the European continent.
"The results are that it is H5N1 but further laboratory results are required in order to confirm the origin of the virus," said a spokesman for the UK agriculture ministry.
Romanian officials have said further drastic measures will be needed to contain the outbreak.
Domestic poultry has already been culled in the affected area, and a 3km quarantine zone has been set up around it.
The BBC also has an article explaining some precautionary measures other European countries are taking.

Bird Flu Continues to Spread
The deadly H5N1 strain of bird flu has been confirmed Turkey. Meanwhile, the BBC reports that the bird flu discovered in Romania has been discovered in another flock of birds in that country 30 kilometers away.
Results showing whether this case, or the earlier confirmed outbreak, is the lethal H5N1 strain found in Turkey are expected in the coming days.
The World Health Organization says there is a high probability that the first birds did carry that strain.
The news comes as EU veterinary officers hold an emergency meeting to discuss measures to contain bird flu.
In Turkey and Romania, the sites of bird flu infection have been close to areas favoured by migratory birds.
The bird flu has not yet been confirmed as H5N1 in the birds found in Romania. If migratory birds are carrying the virus then a continued spread of the disease -- at least in birds -- seems likely.

Google Powered UFO Map Site Launches
A new website called UFO Maps combines UFO reports with a Google maps overlay. The website puts little clickable UFO icons on the map to represent where a UFO report took place. You can click on the UFO icon to learn more about each UFO report. There were quite a few reports in September primarily in the Midwest, which looks like it is being invaded. As UFO Maps points out Wikipedia's UFO entry lists some of most frequently reported characteristics of UFOs.
Saucer, toy-top, or disk-shaped "craft" without visible or audible propulsion. (day and night)
Rapidly-moving lights or lights with apparent ability to rapidly change direction ? the earliest mention of their motion was given as "saucers skipping on water." Disc-shaped craft are sometimes reported to move in an irregular or "wobbly" manner at low speeds.
Large triangular "craft" or triangular light pattern
Cigar-shaped "craft" with lighted windows (Meteor fireballs are sometimes reported this way)

Vince Surprises Spain. Two Storms Until Alpha.
The record setting Hurricane season of 2005 continues with a first tropical storm ever for Spain. Vince, the 20th storm of this incredibly active season, is Spain's first tropical storm in recorded history according to the National Hurricane Center (NHC). Here is an except from the offical NHC discussion about Vince making landfall in Spain.
THE HISTORICAL RECORD SHOWS NO TROPICAL CYCLONE EVER MAKING LANDFALL
ON THE IBERIAN PENINSULA. BASED ON SURFACE REPORTS FROM FARO
PORTUGAL...THE CENTER PASSED JUST TO THE SOUTH OF THE COAST OF
PORTUGAL...BEFORE BECOMING THE FIRST TROPICAL CYCLONE TO MAKE
LANDFALL IN SPAIN.
Vince leaves us just two storms away from a Tropical Storm Alpha or Hurricane Alpha. The next storm name available is Wilma and after Wilma the names will come from the Greek alphabet.

1918 Flu Pandemic Was Avain Flu Strain
Scientists studying the deadly 1918 flu strain that killed approximately 50 million people worldwide have discovered that the 1918 flu also came from birds. This makes it similar to H5N1, the deadly bird flu virus that infectious disease experts are concerned could create a modern pandemic killing tens or hundreds of millions of people. H5N1 has killed 65 people so far according to the BBC article. H5N1 has not yet acquired the ability to transmit easily from person to person -- it is this step that could lead to the global pandemic.
Working on virus samples from the remains of victims of the 1918 pandemic, the researchers were able to piece together the entire genetic sequence of the virus.
They found the virus contained elements that were new to humans of the time - making it highly virulent.
And analysis of the final three pieces of the virus' genetic code has revealed mutations that have striking similarities to those found in flu viruses found only in birds, such as the H5N1 strain currently found in south east Asia.
NBC5.com's Dr. Malloy also has a helpful Question and Answer article that answers some basic questions about bird flu that he has received.
What exactly is bird flu?
Bird flu is a viral infection carried by wild birds. It has now spread to domesticated birds and has killed over 100 million of them. Now the bird flu virus has shown it can easily mutate and in some instances make a direct jump from birds to people. Thee have been at least 100 human cases mainly in the far east with the most case occurring in Vietnam.
When did the first human case occur?
1997
Why is bird flu different from regular flu?
Bird flu is genetically different and much more lethal with over half the victims dying. The most deadly type of bird flu virus is H5N1 and it is very similar genetically to the 1918 Spanish Flu that killed 59 million worldwide.
The BBC also offers a Q and A page. More resources can be found on the CDC's Avian flu page. Past bird flu coverage in the Science News Blog can be found here

Media Access to Government Meteorologists Restricted?
A report in the Raw Story says that media requests for interviews with meteorologists from National Oceanic and Atmospheric Administration (NOAA), including the National Weather Service (NWS), now has to be approved first by the Department of Commerce. Some NOAA mets were surprised when they were informed by Raw Story of this change.
"I have been worked for NOAA for roughly 15 years," said a NOAA employee speaking of both the Department media policy and the Teet email. "There has never been a blanket policy of needing approval before granting an interview with a national media outlet."
Another NOAA employee, also wishing to remain anonymous, concurred.
"This is a big change in our policy with the media," he said. "This comes all the way down from DOC," he added, indicating that such media decisions were formerly made at the local level.
It isn't clear why interview requests can no longer be handled by the local NWS centers but at a minimum it ads another layer of bureaucracy to the interview process. The Raw Story article has a copy of the memo that was sent to NOAA employees about the change in procedure. The new procedure makes little sense and seems likely to slow down the transfer of information from the NOAA and the NWS to the public.

Bees Defend Hive From Hornest With Heatballing Defense
If you have seen the 30 hornets vs. 30,000 bees video then you know the devastation a few hornets can cause a hive of bees. Fortunately, there a few honeybee species that defend themselves with a technique called heatballling where lots of bees surround a hornet raising the internal temperature and killing the wasp with their body heat. A Sciencenews.org article explains how the special honeybee defense works.
However, a few honeybee species can defend themselves by surrounding an invader. Researchers used to think that the few-dozen bees were trying to sting the wasp, says Seeley. Thermal cameras, however, revealed the balls' soaring heat.
To see what margin of safety the bees have, Tan and his research colleagues presented tethered wasps to six colonies each of native Asian bees and European bees. At each nest, worker bees engulfed the wasp immediately. Within 5 minutes, the center of a typical bee ball had reached 45?C.
To check the bees' and wasps' tolerance for heat, researchers then caged each of the species in incubators and systematically cranked up the temperature. The wasps died at 45.7?C, but the Asian honeybees survived heat to 50.7?C and the European bees made it to 51.8?C.
The native Asian bees, ancient adversaries of the wasps, mobilized half again as many defenders into a heat ball as the European bees did, the researchers report. Furthermore, Asian bees not mobbing the wasp were more likely to take shelter during an attack than bystander European bees were.
At least some bees can defend their nests.

Young Luke Uses Science to Solve Problems
Luke Shakespeare is only 11 but he has already won awards for math, science, photography and poetry. The Syndey Morning Herald says Luke's latest project was an investigation into how rock climbers can reduce muscle strains using goniometry.
Luke burst onto the science scene aged 8 and his CV is now two-pages long. For his latest experiment, he used goniometry (the science of measuring joints) to investigate how rock climbers can avoid muscle strains.
"I was rock climbing and my arms started to hurt," he said. "I was only climbing for three minutes. So I was like, 'How can you fix this?' Then we walked through St Vincent de Paul and I saw a book on goniometry." Luke studied rock climbers' positions, found correlations between repetitive movements, then designed a measuring device to work out how to reduce repetitive strains. If climbers were then educated about these strains and could use different movements, he concluded, they should be able to reduce tendon, ligament and muscle problems. The project won a national Australian Association of Mathematics Teachers' award.
The Herald also says Luke wants to be a basketball player and if that fails he will look into rocket science. With the kind of mind it sounds like Luke has it seems unlikely he will be able to avoid science.

Rita Surge Devastates Cameron Parish
The USGS Coastal and Marine Geology Program has conducted some Hurricane Rita impact studies and the results are very alarming. The surge from Hurricane Rita completely wiped out small buildings and homes in Cameron Parish, Louisiana. The USGS has provided several before and after comparison photos like the one on the right to show the devastation. The surge was 20 feet is some areas. The photograph comparison on the right is from Holly Beach and as you can see the surge completely wiped out the buildings located near the shoreline.
The beaches of Cameron Parish, Louisiana were located just east of the point of landfall for Hurricane Rita, in the right-front quadrant where winds and surge were a maximum. Some small towns in this zone no longer have any structures remaining. The combination of low elevations and a storm surge approaching 6 m (20 ft) that swept across the coast, resulted in bare concrete slabs and less-than-vertical pilings where buildings had been located.
Be sure to visit the USGS page for more comparison photographs.
