Scientific and Recreational Diving in Thunder Bay National Marine Sanctuary

Thunder Bay National Marine Sanctuary (TBNMS) is primarily known for its vast number of shipwrecks. An estimated 200 shipwrecks reside within and just outside the sanctuary’s waters. These wrecks range from nineteenth century lake schooners and paddleboats to perhaps Thunder Bay’s last wreck, the German freighter Nordmeer, which wrecked near Thunder Bay Island in 1966.

Each year hundreds of recreational divers come to TBNMS to brave the chilly waters of Lake Huron for a chance to glimpse sunken history. In addition to the recreational divers, the sanctuary has a team of scientific and archaeological divers working to protect, preserve and learn more about the sanctuary’s known wrecks as well as research and explore for undiscovered wrecks.

Scientific diving requires additional skills and training above and beyond what is required for a typical recreational diver. While diving to depths greater than 30 meters can be considered advanced for a recreational diver, imagine having to dive to that depth and greater to set up equipment or take samples!

The chilly water temperatures of Lake Huron also require divers to use dry-suits almost all year long. Water near the bottom of the Middle Island Sinkhole in early September is a brisk 38 degrees Fahrenheit!

TBNMS divers have played an important role in sinkhole exploration. Scientists depend on the divers to collect samples of the purple and white microbial mats at the bottom of the sinkhole and deploy and position instrumentation, such as the respiration chambers and tripods for accurate data collection. Divers also provide underwater photographs and video of the sinkholes.

What is Geothermal Energy

Several technologies have been urbanized to take benefit of geothermal energy. Geothermal is the heat from the earth. This heat can be drawn from the earth using many sources like hot water or steam reservoirs deep in the earth that are accessed by drilling; geothermal reservoirs located near the earth's surface, mostly located in western states, Alaska, and Hawaii; and the shallow ground near the Earth's surface that maintains a relatively constant temperature of 50°-60° F.

This variety of geothermal resources allows them to be used on both large and small scales. A utility can use the hot water and steam from reservoirs to drive generators and produce electricity for its customers. Other applications apply the heat produced from geothermal directly to various uses in buildings, roads, agriculture, and industrial plants. Still others use the heat directly from the ground to provide heating and cooling in homes and other buildings.

Other geothermal resources exist miles beneath the earth's surface in the hot rock and magma there. In the future, these resources may also be useful as sources of heat and energy.

Scottish embryologist Ian Wilmut presented Dolly, the cloned sheep, to a surprised world, ethicists and policymakers have been striving with the settling implications of his study. For years, cloning of adults, animals or humans has been largely the stuff of science invention. Because the successful cloning of a six-year-old sheep, many of the assumptions and questions being raised have roots in the fictional: Could Hitler or the Incan Ice Mummy brought back to life? Would humans be cloned only to cannibalize their organs?

Uses of Cloning
• The production of animals engineered to take human genes for the making of certain. proteins that could be used as drugs; the proteins would be take out from the animal’s
milk and used to treat human diseases
• The mass creation of livestock that have been hereditarily customized to possess certain desirable behavior.
• The upholding of endangered species.
• The production of offspring by infertile couples.
• The production of offspring frees of a potentially disease-causing genetic fault carried by one member of a couple; the person without the defect could be cloned.

From few years now India may not have goa beach.

One of the India's most beautiful beaches is the Goa beach.

One monsoon night in the year 2000, a 240 m long ship, River Princess, broke its anchor and got stuck ion cost . Since then it hasn't budged and the result? Twenty thousand tonnes of rusting metal, on Goa's beaches. This has led to an environmental disaster as these beaches are now almost on the verge of disappearing as the ship interferes with the natural movement of sand.

The Goa government has been accused for not taking any action to remove this ship. Now, 9 years later, just before this monsoon, the government seems to have woken up. The government is placing massive tubes, which they hope will serve as artificial sand dunes, like shock-absorbers between the land and the sea. Tubes cost Rs 6 crore.

The government even introduced a new law that enabled them to remove the ship.
They have permitted this to deliberately degrade and that is the shameful part.
But the damage is more widespread. Scientists say, while Goa thrives on tourism, the industry is also answerable for coastal degradation.

With no one to check its 100 kms seashore line sand dunes and plants on the beaches have been wiped off destroying much of the coasts natural security system.

Swine Flu: HK Quarantines Hundreds At Hotel

Swine Flu
Hundreds of tourists and employees were under quarantine in a downtown Hong Kong hotel Saturday after a Mexican guest tested positive for swine flu. With the outbreak on its doorstep, China suspended direct flights from the Latin American country.

Hours after the first confirmed case in Asia was reported, the continent got its second: Tests showed a South Korean woman also had the disease. She has been under quarantine since returning earlier this week from Mexico, the epicenter of the disease.

Sixteen people in Mexico and one toddler in the U.S. have died from the disease. More than 650 cases have been confirmed worldwide, with 397 in Mexico. Canada, Israel, New Zealand and more than a half-dozen European countries have also confirmed cases.

Fashion Life

Not content with offering cut-price lobsters and champagne Aldi supermarkets have ventured into the beauty world. And the product that’s hitting the headlines is called Lacura Wrinkle Stop and costs £6. And why is it causing a commotion? For two reasons - it claims to be the new Botox and it contains a form of snake venom.

This isn’t the first time a “snake venom” like substance has been used in creams, the featured image is of Planet Skincare’s daily moisturiser which costs up to £60 per pot. It literally flew off the shelves when Selfridges first introduced it, and top starlets including Hilary Swank are said to be fans.

SkincareThe chemical involved isn’t exactly snake venom, but a synthetic form based on the paralysing effects of the Asian temple viper snakes. Yes that’s right paralysing effects, hence why it’s the new Botox, the idea is that it stops those pesky nerve signals so your face doesn’t contract which means you can’t get lines. The synthetic venom is called Syn-Ake. Testers claimed that with a twice daily application for four weeks a 52% reduction in the appearance of wrinkles was noted.

It is very interesting, and is sure to cause bedlam in Aldi supermarkets on 20th April. I’m personally a bit of a sceptic about these things, I believe in daily moisturising and SPF 15 every day. But there is no doubt that we all want to look younger and this is preferable to Botox as there’s no injecting poisonous chemicals into your skin. What do you make of anti-aging products? Are they real or just a scam? Will you be trying this snake venom cream?
