A`LA CARTE: ICY COLD SCIENCE

Summer is coming. The time of camping and icy cold drinks. I've been working on developing a freeze dried beer that comes in a small pack and rehydrates fully carbonated with all its alcohol intact. Once it goes to market you can say you knew me when. In the meantime, I can help with getting that warm six pack or vodka cooler cold in minutes. Geeky, yes, and yet you'll be so much more popular at summer parties.

Understanding how salt and ice interact will save you from many a warm bevvie this summer. Water freezes at 32 degrees F. (0 degrees C ) When the compound salt is added to water and ice, a new solution with a lower freezing temperature is formed. As the salt and ice molecules mix, the melting ice takes up heat energy from its surroundings and the surrounding water cools down fast.

Why should you care? Well, this little scientific nugget can keep you from ever having to drink warm drinks again. Instead of dropping your warm beverages into a cooler with ice, try adding water and a healthy dose of salt. And, there's no need to worry if some of that salt spills over into your drink. A little salt is good for you. Balances the electrolytes and makes tequila go down easier.

If you are in North America, you will likey be using iodized salt, which is table salt mixed with a minute amount of potassium iodide, sodium iodide, or sodium iodate. Iodized salt is used to bump up the amount of iodine in our systems and protect us from endemic goiter, a thyroid condition that arises from lack of iodine. In Europe, sodium fluoride or potassium fluoride is the more common additive, especially if they do not add fluoride to their drinking water. You may notice this in France. You'll also notice a slight yellowish tinge to the salt. Don't panic. Different culprit than yellow snow. They add a wee bit of Vitamin B9, hence the discoloration.

No matter which salt you choose, bada bing... icy cold bevvies in minutes.

ROMANIA: 35,000 YEAR-OLD HUMAN REMAINS

If Van Helsing were poking around Transylvania these days, chances are he'd be more likely to be looking for the decaying remains of 35,000 year old humans than blood drinking vampires. Romania's dark history extends back way past the days of Vlad.

It seems vampires and ghouls aside, something darker and much more interesting lurks in that eastern belly. I travelled to Transylvania last year and spent some time in Cluj, the newly minted anthro-capital of Romania. I was lucky enough to brush shoulders and prep tools with paleoanthropologists working on a new find that changes what we know about early human activity in Eastern Europe.

The remains of a man, woman and teenage boy -- the first Romanian family if you will... tell the most complete picture of what our ancestors were like some 35,000 years ago, shedding a bit of light on a black box in history. International scientists have been carrying out further analysis to get a clearer picture on the find, said anthropologist Erik Trinkaus, of Washington University in St. Louis.

It is clear that, "this is the most complete collection of modern humans in Europe older than 28,000 years," he told The Associated Press. "We are very excited about it," And they have reason to be. The find is changing perceptions about modern humans. Romanian recreational cavers unearthed the remains of three facial bones last year, and gave them to Romanian scientists. Romanian scientists asked Trinkaus to analyze the fossils, and he traveled to the Romanian city of Cluj this week with Portuguese scientist Joao Zilhao , a fossil specialist.

They also found a jawbone that belonged to a man who could have been around 35. Silhao also found part of a skull and teeth belonging to a teenage male, and female temporal bone.

"This was 25,000 years before agriculture. Certainly they were hunters," said Trinkaus . He said the bones were discovered in the foothills of the Carpathian Mountains . Trinkaus said the humans would have had religious beliefs, used stone tools, and a well-defined social system and lived in a period in during which early modern humans overlapped with late surviving Neanderthals in Europe.

Humans survived because the area was ecologically variable being close the Banat plain and close to the mountains. A team of international scientists from the United States , Norway , Portugal and Britain will return to the cave to continue their field work next year. Look out Van Helsing, there are new kids in town and they look to be very, very interesting.

DINOSAUR DISCOVERY IN TUMBLER RIDGE

Today is the First Annual Peace Region Palaeontology Symposium in Tumbler Ridge, an an important milestone for Tumbler Ridge and the Peace Region. Daniel Helm's find of dinosaur tracks along a river near the town of Tumbler Ridge sparked a new paleo craze in the town. I met with Daniel and Charles Helm back in 2005 at the British Columbia Paleontological Symposium. The photo above is from their original workshop that has now blossomed into a fully operation paleontological centre.

Congrats to the Peace Region Palaeontological Society! I'm sure this symposium marks the first of many great educational events.

GODS & CEPHALOPODS

A great temple to the god Amon was built at Karnak in Upper Egypt around c. 1785. It is from Amon that we get his cephalopod namesake, the ammonites and also the name origin for the compound ammonia or NH3.

Ammonites were a group of hugely successful complex molluscs that looked like the still extant Nautilus, a coiled shellfish that lives off the southern coast of Asia. While the Nautilus lived on, ammonites graced our waters from around 400 million years ago until the end of the Cretaceous, 65 million years ago.

Varying in size from millimeters to meters across, ammonites are prized as both works of art and index fossils, geological time markers, helping us date rock. They have proven especially useful for proving time markers for the strata of the Cretaceous System along the west coast of North America.

The ammonites with their hard exoskeleton, chambers and soft interior, were kissing cousins in the Class Cephalopoda, meaning "head-footed," closely related to modern squid, cuttlefish and octopus. Cephalopods have a complex eye structure and were excellent swimmers. Ammonites used these evolutionary benefits to their advantage, making them one of the most successful marine predators of ancient Cretaceous seas.

PADDLING WIDGEON ESTUARY

Interested in getting out on the water? Head out for a relaxing day paddle or overnight to Widgeon Estuary. The paddling is easy. You can do the trip via kayak or canoe and can stay for the night or do it as a day trip. I like to to camp near the base of the trail to the falls.

There is nothing better than to cruise flat water with rippling reflections of big snowy mountains cascading off your bow. The estuary of Widgeon Creek at the south end of Pitt Lake at Grant Narrows is the perfect place to enjoy this sensation.

If you like quiet peaceful waterways teaming with bird life this is the place to go for the whole estuary is a protected bird sanctuary. After making the 300m crossing of Grant Narrows, expect to see tons of waterfowl and other species from herons to harlequins that make this area their habitat. You might even see a fleeting glimpse of muskrat or beaver if you are lucky.

If Widgeon Creek is high in the spring or early summer you can paddle quite a distance up under lazy overhanging branches draped in moss and lichen. Huge lush ferns and skunk cabbage line the shoreline in the marshy areas and neat little gravel bars are gathered in the bends of the creek. When you are there you will be amazed that you can be so close to the city yet so far away.

A campsite is located near the west end of the estuary if you want to stay longer. This is probably best to do in the shoulder season when it isn't so busy. If the water is high more secluded sites are located up the river.

EIGHTH BC PALEONTOLOGICAL SYMPOSIUM

KWAK'WAKA'WAKW MATRILINE AND PATRILINE

The Kwakwaka’wakw are characterized by a particular iconographic promiscuity, a tendency to mobilize a diverse set of visual, material, or performative signs that index their individual standings. There may be various explanations for this. 

The Kwakwaka’wakw are geographically and culturally at the point on the central coast where the strictly matrilineal groups of the north (e.g., Tlingit, Haida, Tsimshian) give way to more patrilineal and less clan/crest-based patterns of descent in the south (Nuu-Chah-Nulth and Coast Salish), and they have long been known as the grand synthesizers of the region. 

Bilateral reckoning of Kwakwaka’wakw descent entails the claiming of crest images and personal prerogatives from both the matriline and patriline, increasing the number of images an individual might legitimately display. 

They developed and maintained through the assimilationist period the most elaborate system of restricted ceremonial performance of the famous ‘‘secret’’ or ‘‘dance’’ societies described by Franz Boas (1897) and Philip Drucker (1940) which is predicated on rather flexible and negotiated hereditary rights to (often multiple) ritual dramas and the accompanying regalia (see Roth 2002:144). 

The Kwakwaka’wakw have long proved remarkably amenable to participating in their own ethnographic representation, from adapting their visual motifs and performances to intercultural contexts of display, to applying the technologies and institutions of modernity to their own modes of cultural production (Glass 2004, 2006)

INSIGHT: ICE CORE LOOKING GLASS

Evidence from the past provides a window into the Earth's future. A sediment core from 400m below the seabed of the Arctic Ocean showed that Fifty-five million years ago, deep in the Eocene, the North Pole was ice-free and enjoying tropical temperatures. It also tells us that the temperature of the ocean was 20C, instead of the coolish –1.5C we see today… a truth that is hard to imagine with all the press surrounding global warming.

The bottom end of that core helped explain the fossils found at Eocene sites around British Columbia, species commonly seen in more tropical environments today. The warmer temperatures seen at McAbee and around the globe were recorded in the core sample and reveal evidence for a global event known at the Palaeocene-Eocene Thermal Maximum. Back in the Eocene, a gigantic emission of greenhouse gases was released into the atmosphere and the global temperature warmed by about 5C.

While the bookends of the geologic time scale slide back and forth a wee bit, the current experts in the geologic community set the limits to be 33.9 +_ 0.1 to 55.8 +_ 0.2 million years ago. The fossil record tells us that this part of British Columbia and much of the Earth was significantly warmer around that time, so warm in fact that we find temperate and tropical plant fossils in areas that now sport plants that prefer much colder climes, or as is the case in the Arctic, snow and ice.

The Okanagan Highlands is an area centred in the Interior of British Columbia, but the term is used in a slightly misleading fashion to describe an arc of Eocene lakebed sites that extend from Smithers in the north, down to the fossil site of Republic Washington. The grouping includes the fossil sites of Driftwood Canyon, Quilchena, Allenby, Tranquille, McAbee, Princeton and Republic. These fossil sites range in time from Early to Middle Eocene, and the fossil they contain give us a snapshot of what was happening in this part of the world because of the varied plant fossils they contain..

While the area around the Interior of British Columbia was affected. McAbee was not as warm as some of the other Middle Eocene sites, a fact inferred by what we see and what is conspicuously missing.

The plant species suggest that McAbee had a more temperate climate, slightly cooler and wetter than other Eocene sites to the south at Princeton, British Columbia and Republic and Chuckanut, Washington. Missing are the tropical Sabal (palm), seen at Princeton and the impressive Ensete (banana) and Zamiaceae (cycad) found at Republic and Chuckanut, Washington.

While we are the likely culprits of much of the warming of the Arctic today, the sediments of McAbee tell us that natural processes operating in the not too distant past have also resulted in significant temperature fluxuations on a world-wide scale.

"LOOK, LOOK, LOOK" A DAY AT THE ZOO

If you are feeling a bit hemmed in from all the cold weather, bundle up and take a trip to the Vancouver Aquarium, Science World or your local museum.

There is nothing more exciting than witnessing the awe on a child's face as they begin to explore the natural world.

If you've got a thing for fossils, remember to check out the ancient critters as well. The Royal BC Museum, Qualicum Beach Museum an Courtenay Museum all have permanent fossil displays. If you are in Vancouver, head on down to Science World to see their T-Rex. There re also many fossil exhibits planned at the new Beatty Biodiversity Museum openig later this year at UBC.
