Sarasota sea life massacre

Original image

According to this story, the red tide currently floating off the coast of Sarasota "has not killed fish or caused respiratory problems on Siesta Public Beach, Sarasota County's biggest tourist beach."

Um, wrong.

There were hundreds, maybe even thousands, of dead fish on that particular beach yesterday -- mostly the ones in the cell-phone pic above, but also some pufferfish (pictured after the jump) and pinfish. About an hour up the road, snook have also been dying, apparently because of an underwater explosion. We think it bears repeating: It's hard out there for a fish.

By the way, the toxin involved in some red tides has a long and storied history involving, among others, Richard Nixon and the CIA. Find out about it here, or after the jump.

A more insidious aspect of the colourful history of saxitoxin has to be its involvement in covert government operations and in chemical warfare. Saxitoxin is about 1000 times more toxic than a typical synthetic nerve gas such as sarin, and it is perhaps not surprising that in the 1950s, the CIA began experimenting with it, reportedly using it in suicide capsules provided to its agents (notably U-2 pilot Francis Gary Powers).

In 1970, President Nixon ordered the CIA to destroy its entire stock of saxitoxin, painstakingly collected over several years, as part of the US commitment in accordance with the United Nations agreement on biological weapons. Nowadays, saxitoxin and ricin are the only two natural toxins classified as Schedule 1 Chemical Warfare Agents. However, in 1975 William Colby, the CIA Director, revealed to Congress that they still possessed over 10 grammes of the material in downtown Washington. Luckily, this supply of saxitoxin was eventually distributed to scientists and medical researchers under the auspices of the National Institutes of Health (NIH).

In connection with this, STX, like many other naturally occurring toxins, has been an indispensible tool in medical research. It is a potent and extremely selective sodium-channel blocker, having no effect on potassium or calcium channels, or the flux of chloride ions, or indeed on acetylcholine release (whereas other marine toxins have similarly selective effects on these aspects of nerve function). Saxitoxin has been used for the labelling, characterisation and isolation of various sodium channel components, and this has opened up new avenues for the study of various nervous disorders.

Google Street View Now Lets You Explore the International Space Station

Google Street View covers some amazing locations (Antarctica, the Grand Canyon, and Stonehenge, to name a few), but it’s taken until now for the tool to venture into the final frontier. As TechCrunch reports, you can now use Street View to explore the inside of the International Space Station.

The scenes, photographed by astronauts living on the ISS, include all 15 modules of the massive satellite. Viewers will be treated to true 360-degree views of the rooms and equipment onboard. Through the windows, you can see Earth from an astronaut's perspective and a SpaceX Dragon craft delivering supplies to the crew.

Because the imagery was captured in zero gravity, it’s easy to lose sense of your bearings. Get a taste of what ISS residents experience on a daily basis here.

6 East Coast Castles to Visit for a Fairy Tale Road Trip
Original image

Once the stuff of fairy tales and legends, a variety of former castles have been repurposed today as museums and event spaces. Enough of them dot the East Coast that you can plan a summer road trip to visit half a dozen in a week or two, starting in or near New York City. See our turrent-rich itinerary below.

STOP 1: BANNERMAN CASTLE // BEACON, NEW YORK

59 miles from New York City

Bannerman Castle can be found on its very own island in the Hudson River. Although the castle has fallen into ruins, the crumbling shell adds visual interest to the stunning Hudson Highlands views, and can be visited via walking or boat tours from May to October. The man who built the castle, Scottish immigrant Frank Bannerman, accumulated a fortune shortly after the Civil War in his Brooklyn store known as Bannerman’s. He eventually built the Scottish-style castle as both a residence and a military weapons storehouse starting in 1901. The island remained in his family until 1967, when it was given to the Taconic Park Commission; two years later it was partially destroyed by a mysterious fire, which led to its ruined appearance.

STOP 2. GILLETTE CASTLE STATE PARK // EAST HADDAM, CONNECTICUT

116 miles from Beacon, New York

William Gillette was an actor best known for playing Sherlock Holmes, which may have something to do with where he got the idea to install a series of hidden mirrors in his castle, using them to watch guests coming and going. The unusual-looking stone structure was built starting in 1914 on a chain of hills known as the Seven Sisters. Gillette designed many of the castle’s interior features (which feature a secret room), and also installed a railroad on the property so he could take his guests for rides. When he died in 1937 without designating any heirs, his will forbade the possession of his home by any "blithering sap-head who has no conception of where he is or with what surrounded.” The castle is now managed by the State of Connecticut as Gillette Castle State Park.

STOP 3. BELCOURT CASTLE // NEWPORT, RHODE ISLAND

74 miles from East Haddam, Connecticut

Prominent architect Richard Morris Hunt designed Belcourt Castle for congressman and socialite Oliver Belmont in 1891. Hunt was known for his ornate style, having designed the facade of the Metropolitan Museum of Art and the Breakers in Newport, Rhode Island, but Belmont had some unusual requests. He was less interested in a building that would entertain people and more in one that would allow him to spend time with his horses—the entire first floor was designed around a carriage room and stables. Despite its grand scale, there was only one bedroom. Construction cost $3.2 million in 1894, a figure of approximately $80 million today. But around the time it was finished, Belmont was hospitalized following a mugging. It took an entire year before he saw his completed mansion.

STOP 4. HAMMOND CASTLE MUSEUM // GLOUCESTER, MASSACHUSETTS

111 miles from Newport, Rhode Island

Inventor John Hays Hammond Jr. built his medieval-style castle between 1926 and 1929 as both his home and a showcase for his historical artifacts. But Hammond was not only interested in recreating visions of the past; he also helped shape the future. The castle was home to the Hammond Research Corporation, from which Hammond produced over 400 patents and came up with the ideas for over 800 inventions, including remote control via radio waves—which earned him the title "the Father of Remote Control." Visitors can take a self-guided tour of many of the castle’s rooms, including the great hall, indoor courtyard, Renaissance dining room, guest bedrooms, inventions exhibit room, library, and kitchens.

STOP 5. BOLDT CASTLE // ALEXANDRIA BAY, THOUSAND ISLANDS, NEW YORK

430 miles from Gloucester, Massachusetts

It's a long drive from Gloucester and only accessible by water, but it's worth it. The German-style castle on Heart Island was built in 1900 by millionaire hotel magnate George C. Boldt, who created the extravagant structure as a summer dream home for his wife Louise. Sadly, she passed away just months before the place was completed. The heartbroken Boldt stopped construction, leaving the property empty for over 70 years. It's now in the midst of an extensive renovation, but the ballroom, library, and several bedrooms have been recreated, and the gardens feature thousands of plants.

STOP 6. FONTHILL CASTLE // DOYLESTOWN, PENNSYLVANIA

327 miles from Alexandria Bay, New York

In the mood for more castles? Head south to Doylestown, Pennsylvania, where Fonthill Castle was the home of the early 20th century American archeologist, anthropologist, and antiquarian Henry Chapman Mercer. Mercer was a man of many interests, including paleontology, tile-making, and architecture, and his interest in the latter led him to design Fonthill Castle as a place to display his colorful tile and print collection. The inspired home is notable for its Medieval, Gothic, and Byzantine architectural styles, and with 44 rooms, there's plenty of well-decorated nooks and crannies to explore.
