NATURE'S BLUEPRINT

The exposed structural roots of this ancient Great Basin bristlecone pine resemble arms like that of a giant squid. White Mtns, Calif, Earth Dr Reese Halter's root research circa 1989

The antiquitous sedimentary White Mountains of east central California are home to the world’s oldest living trees – the venerable Great Basin bristlecone pines. Some of these trees have witnessed more than 1.68 million sunrises.

It seems fitting that the oldest trees on Earth should be living on layers of rock that started as sand and mud or shells deposited on the bottom of a shallow, warm sea 600 million years ago.

The White Mountains are the second highest in California next to the Sierra Nevada’s and the third-highest peak at 14,246 feet above sea level. Being located just east of the Sierra’s means that the White Mountains are dry. Most of the scant precipitation falls as snow, the remainder comes as isolated thunderstorms. From November to April the climate is inhospitable with 100 mile per hour winds occurring frequently.

At two miles above sea level the ultraviolet radiation is extreme. July and August are the hottest months, with average temperatures rarely exceeding 50 degrees F. and precipitation is a meager 12 inches per year.

The red-ochre or salmon-colored coastal wolves along the Great Bear Rainforest or mid-coastline of British Columbia are unique and dependant upon intact old growth forests that provide habitat for salmon bearing streams.

Wolves, similarly to humans and a few other highly social animals, work co-operatively by utilizing a division of labor.

Over the past 300 years in North American humans of European descent have relentlessly hunted wolves. In fact, the British Columbia coastal wolf population has been drastically reduced by at least 80 percent.

Coastal wolves are the least known subspecies of gray wolves left on the planet. They live in rugged yet picturesque terrain, which receives more than 7 feet of precipitation annually.

Sonoran Desert

Recently, I had a chance to spend a couple days exploring Arizona’s Sonoran Desert. It’s truly amazing to see how all the different animals use the desert to make a living.

The Sonoran Desert is spread across 106,000 square miles with about 40 percent of it in the U.S. and 60 percent in Mexico. It ranges in elevation from near sea level to over 3,300 feet along the eastern edge of Arizona. In Arizona it receives both winter and summer precipitation with an annual average of about 13 inches.

It is the most biologically diverse of the four big North American deserts. In fact, there are more than 1,000 species of solitary and social bees in the Sonoran Desert – more than anywhere else on the globe.

A mass of plastic in the Pacific, increasing tenfold each decade since 1945, is now the size of France and killing everything in its wake. And recently masses of plastic likened to toxic chunky soup has been documented in both the Indian and Atlantic Oceans as well as the Mediterranean Sea.

In America consume and discard 33 billion plastic disposable beverage bottles a year. Tens of millions of those bottles are now in the oceans.

Globally, 280 million metric tons of plastic are generated each year. Over 3.5 million pieces of plastic enter the oceans every year. The United Nations Environmental Program now estimates that there are 46,000 floating pieces of plastic for every square kilometer of ocean. Some of that trash circulating the globe is 95 feet deep.

Ever wonder why ice cream at the bottom of the carton is chewy and filled with frost? With U.S. sales in 2010 at over $10 billion and more than 1.5 billion gallons of U.S. ice cream produced in 2011, Nestle – the world’s largest food company wants answers.

Nestle scientists are looking to nature for help in revealing exactly which mechanism within ice crystal dynamics is responsible for taking the fun and flavor away from ice cream as it ages in home-freezer’s.

If you are now wondering about ice crystals within ice cream, it turns out that one of nature’s fiercest winter events – avalanches – hold many answers to making tastier ice cream.

Avalanches kill more than 150 people a year around the globe – mostly snow mobiliers, skiers and snow boarders. Imagine a massive slab of snow breaking loose from a mountainside, shattering like broken glass, moving in excess of 80 mph within 5 seconds, and carrying 20 football fields, 10 feet deep with snow. It’s a backcountry enthusiast’s worst nightmare.

So what causes avalanches? And why exactly would Nestle food scientists be interested in them?

Snowpacks are made up of layers of accumulated winter snow. Each layer contains ice grains constantly changing from smaller to larger crystals. Larger ice crystals are weaker because they have fewer bonds compared to smaller more rounded crystals, which are packed snuggly together (just like ice cream when it’s first made and frozen).

Avalanches occur when snowstorms or rainstorms add heavy weight causing instability within existing snowpack layers. In fact, rain in the mountains acts like a lubricant facilitating layers within a snowpack to unlock and slip-slide away.

Avalanche research over the past half century has closely examined the life history and growth of ice crystals as influenced by temperature.

The Institute for Snow & Avalanche Research in Switzerland (SLF) at Davos uses the world’s only x-ray tomography machine to time lapse study ice crystals at temperatures between 32 and minus 4 degrees Fahrenheit. Coincidentally, most home-freezer settings are maintained at the lower end of this range.

The dynamics of ice cream crystals are in many ways similar to the ever-changing ice crystals within mountain snowpacks. So it seemed very logical that Nestle scientists in Vevey, Switzerland should partner with their SLF brethren in Davos, and that’s exactly what they did.

Ice crystals grow because temperatures fluctuate. Home-freezer’s may be set at 0 degrees Fahrenheit but they, too, vary by a couple degrees on either side. Or, when you take the carton out of the freezer to get a few scoops, the ice cream is exposed to room temperature for a minute or so. When this occurs ice cream slightly melts then it refreezes. When ice cream ages the ice separates from the original ingredients of cream and sugar. Over time, ice cream becomes chewy because it looses water and air, or it becomes frosty (due to crystals growing larger similar to conditions in a snowpack) and harder to scoop.

The Nestle scientists are using the non-invasive x-ray tomography to investigate the shape and size of ice crystals and air bubbles in ice cream cartons under home-freezer conditions. By identifying the main mechanism for growth of crystals within ice cream, Nestle scientists will be able to slow it down by altering their receipt, thereby making yummier ice cream that lasts longer.

Coming soon in your favorite ice cream (and Vanilla still remains the most popular followed closely by Chocolate Chip Mint and Cookies & Cream) a tiny mouthful of nature’s avalanche.

Australia possesses some incredible geologic and botanical records. In the west on Mount Narryer there are four billion year old exposed zircons embedded in rocks that are 3.6 billion years old. On the west coast, the first forms of life – cyanobacteria – are found in stromatolites dating back 3.5 billion years. The southeast is home to the awesome Australian Alps, occupying 9,653 square miles (25,000 square kilometers) or 0.3 percent of the continent.

The Australian Alps are about 311 miles (500 kilometers) long and extend from the state of New South Wales through the Australian Capital Territory into the state of Victoria.

The Alps truly have a storied beginning. Five hundred million years ago the Australian Alps were beneath the ocean and made up of the sea floor mud and sand.

The next time you are walking along the seashore, take a closer look at the wave-battered coast. The beauty of this extremely brutal ecosystem is enhanced many fold by a growing understanding of how it works.

There is an intriguing collection of animal and plant life that lives along this edge. They are exposed to harsh physical elements: wind, sun and rain when the water recedes at low tide and waves breaking over them at high tide.

The area between the high and low tides is the inter-tidal zone. I cherish the time to explore this ecosystem.

Have you ever seen a starfish eat a mussel?

One of Earth Dr Reese Halter's students from Cal Lutheran University who will go onto to save the elephants as her life-calling

Elephants have fascinated humankind since early time.

There are two species of elephants: Asian and African, and within the latter there are two subspecies: savannah and forest elephants.

African elephants are heavier – 6 tons and taller – 11 feet at shoulder height compared to Asian’s. In addition, their immense triangular ears extend well beyond their neck. Ear’s of Asian elephants are comparatively small.

African elephants have concave backs, flat foreheads and carry their heads high. The backs of Asians’ are convex, foreheads are twinned domed and they carry their heads low.

In my opinion, Thanksgiving is the best holiday of the year for a number of important reasons. Irrespective of your faith or political beliefs, or lack thereof, our nation takes a day to breathe, reflect upon the past year and give thanks to our loved ones and the Earth’s bounty.

This year, I give thanks in particular for three very special people in my life and 1.8 trillion honeybees that directly account for a quarter of a trillion dollars of commerce, worldwide, annually.

Honeybees are responsible for every third bite on our dinner plate this Thanksgiving and at every meal throughout the year. They pollinate everything from apples to zucchinis, over 100 food crops including half the ingredients in most ice creams. In addition, they are crucial for ensuring alfalfa and clover for the beef and dairy industries around the globe, and annually they help provide 100 million bales of cotton, clothing our species.

But that’s not all; globally honeybees produce over 2.65 billion pounds of honey, 44 million pounds of beeswax, potent pain medicines and now they are going to protect us by sniffing out terrorists, drug lords and horrid diseases.

Honey contains over 200 substances. Bees secrete a glucose oxidase enzyme that assists in converting nectar into honey. Along with oxygen the glucose enzyme splits the glucose molecule into water and hydrogen peroxide. Due to its hydrogen peroxide and glucose oxidase content, honey is a powerful antiseptic.

High amounts of malic, citric, tartaric, oxalic and other organic acids combined with the enzymes catalase and peroxidase give honey its renowned antibacterial properties.

With over 80 percent sugar content and its natural acidity honey creates an inhospitable environment for the single-celled microbes that form infections. The low water content of honey keeps bacteria, which thrives in water, from flourishing. The ancient Mayan Shamans realized this and successfully used honey-based medicines to treat cataracts, conjunctivitis, chills, fevers and open wounds. Today, some modern bandage companies line their products with diluted traces of honey.

Honey is loaded with vitamins and minerals. It contains water soluble B1, B2, B6, panothenic and nicotinic acids, vitamin C — as well as high amounts of fat soluble vitamins E, K and A. Honey also provides us with essential minerals: calcium, phosphorus, potassium, iron, copper, manganese, magnesium and sulfur.

Some of these minerals in the specific concentrations found in honey mimic the concentrations of blood serum. Therefore honey metabolizes easily and can be an important source of essential nutrients. In addition, the combination of glucose and fructose and some maltose, melezitose and dextrin makes honey an excellent source of caloric energy.

Some researchers suggest that a teaspoon or two of honey before bed ensures a restorative sleep. Floridian tupelo and New Zealand manuka honeys are low on the glycemic index and therefore best for diabetics.

Beeswax is a somewhat silent partner in the daily lives of people around the world. From cosmetics, stick colognes, antiperspirants, candies and dental impressions to the mouth-pieces of didgeridoos, beeswax is often an important component.

Did you know that your pool table has beeswax filling its screw holes and seams between slates? Beeswax thread is still preferred by shoemakers — and sailors — because of its durability and resistance to weathering. Furniture and automobile polish, industrial lubricants, paint removers and even the frets on a two-stringed Philippine Kutiyapi boat-lute, they all rely on the wax of the bees.

Did you know that the Roman Catholic Church uses about 3.1 million pounds of beeswax in their candles each year, which are 49 percent beeswax?

Beehives can tell scientists a lot about the health and wellbeing of local environments. In fact, beeswax is a sponge for toxic chemicals. This past springtime researchers examined beehives from 23 states and two Canadian provinces and found 121 different insecticides in 887 samples of bees, wax, pollen and hives.

Of even more concern was that three out of five pollen and wax samples from 23 states had at least one systemic insecticide — a poison designated to spread throughout all parts of the plant including its pollen and nectar. One group of these chemicals, neonictinoids, are lethal to bees, moths, beneficial soil insects and known to contaminate fresh waterways.

Since 1957, the former USSR has used extracts of bee stings — bee venom, known as apis — to treat rheumatoid arthritis, multiple sclerosis and other debilitating autoimmune diseases. The powerful anti-inflammatory effects of melittin and adolapin in bee venom – along with apamin, improve nerve transmission and are being used to effectively treat fibromyalgia and tendonitis. Twelve European countries have officially recognized bee venom solution as a drug.

Bees are man’s best friend, provider and protector; they are being trained in 10 minutes to sniff, with a 98 percent accuracy, enriched uranium, methamphetamine and another 60 lethal and illegal substances. In addition, honeybees are already being used as early detectors of lung and skin cancers, diabetes and TB, as well as to monitor fertility cycles and confirm pregnancies.

Remember, you are what you eat. Visit Farmers’ Markets and buy local organic foods and support local beekeepers by purchasing their honey.

Last year in California, we used 19 billion plastic single-use bags enough to reach to the moon 15 times. Those bags are suffocating 267 marine species (over a million animals) each year; it’s senseless and unacceptable. Wherever you are across our nation or around the globe buy 6 organic cotton shopping bags. Use them instead of supermarket plastic bags. Make it a habit to return those bags to the trunk of your car after unpacking groceries.

This Thanksgiving help our bees by pledging not to use synthetic insecticides, herbicides, fungicides or miticides in your yard.

More than a half a century ago one of the most recognized scientists and arguably brightest mind ever – Dr. Albert Einstein said, “Our task is to widen our circle of compassion beyond a few people to embrace all living creatures and the whole of nature in its beauty.” To encompass this Einstein loved the beauty of bees.

Of the more than 1.6 million known forms of life on our home — planet Earth, bees truly are the “golden-hair” pollinator partners that have been entrusted with sustaining life on land.

Consider that at least 20,000 but perhaps as many as 40,000 species of solitary, stingless, bumble and honeybees quietly have gone about enriching the tapestry of life for over 100 million years.
