Protect your Gonads for around $25.

There’s been plenty of hearty debate between cell phone proponents and critics about potential cancer risks.  After one study claimed cell phones had more detrimental health effects than smoking, a major cancer doctor came forward stating that there was strong upcoming evidence of a cell phone-cancer link, the first time a head of a major academic cancer research institution had suggested such a possibility.

Now another new study has been released citing a decidedly different hazard of cell phone use.  The new study shows that cell phones are no friends of testes, the male reproductive organs in which sperm is made.  In the upcoming study, it was shown that when in close range to the testes and in talk mode, cell phones damage sperm.

The new study is alarming because of two key problems.  First, damaged sperm can lead to birth defects and higher incidences of various disabilities, as seen among the children of older fathers.  Second, the scenario tested in the study is a common one.  Males who chat using hands free headsets often leave their phones resting in their pockets, in perfect range to cause the testes harm.

Ashok Agarwal, who led the study and is the Director of the Center for Reproductive Medicine at the Cleveland Clinic, states, “We believe that these devices are used because we consider them very safe, but it could cause harmful effects due to the proximity of the phones and the exposure that they are causing to the gonads.”

The study consisted of semen samples taken from 32 men, which exhibit similar sperm health.  The samples were kept at constant temperature and other similar conditions, while being split into a control group and a test group.  The test group was placed for an hour within 2.5 cm of a cell phone in talk mode, at 850 MHz, perhaps the most common frequency.

The transmissions led to an apparent increase in oxidative stress, with free radicals and oxidants being created at a higher rate and antioxidants being broken down.  Agarwal says this stress equates to damaged sperm.  Other factors which can cause it include environmental pollutants or infections in the urinary genital tract, he adds.

While the study does not trump up the cancer link, there may be a relation to testicular cancer as well.  Says Agarwal, “On average, there was an 85 percent increase in the amount of free radicals for all the subjects in the study. Free radicals have been linked to a variety of diseases in humans including cancer.” – dailytech

FDA to the rescue (of phone company profits):

The FDA says that cell phone use is safe, based on three large epidemiological studies conducted after 2000. But the agency admits that those studies only followed participants for an average of three years, whereas it regularly takes brain tumors 10 years to develop enough to be detectable. Concerned health professionals have warned that even if the risk from cellular phones is small, the scale on which the phones are used could still lead to a massive public health crisis. An estimated three billion mobile people – 45 percent of the world’s population – use mobile phones. – nn

Oh wait, that was from the “cell phones cause brain cancer” study, not the “cell phones cause sperm damage” study. Here is the cell phone industry answer to the sperm damage study:

Joe Farren, a spokesman for the CTIA was among the cell phone industry leaders who declined to criticize the studies, but argued, “The weight of the published scientific evidence, in addition to the opinion of global health organizations, shows that there is no link between wireless usage and adverse health effects.” But he even added, “We support good science and always have.  It’s important to look at studies that are peer-reviewed and published in leading journals and to listen to the experts.”

Yeah, I don’t know about you, but if any real scientist says this, I’m going to listen to him NOW, not 10 years from now when all the lawsuits from people with deformed kids finally cause the cell phone industry to get one of their experts to say it is true.

That’s why I use XENO’S NARDSAFE(tm) system. I use silver mesh to protect my vital organs from EMF pollution. You should too. You can verify that the mesh works by looking at the bars.  Your cell phone reception will drop to ZERO if the shielding works. I tried it. It works. Take it out to make calls and keep the NARDSAFE between you and the phone during the call. Simple. Cheap.

WARNING: Your cell phone batteries will die quickly. I think my phone turns up the power to try to get a signal and that runs down the battery faster.

Fire shuts 1 unit at Michigan nuclear power plant

A small fire led to the shutdown of one of the two units at a nuclear power plant in southwestern Michigan, utility officials said today. The fire happened Saturday night in a non-nuclear section of the Donald C. Cook Nuclear Plant and there was no release of radioactive material or other danger. No injuries were reported. The cause of the fire wasn’t yet known. American Electric Power Co. spokesman Bill Schalk said today the fire started in a turbine generator that uses steam to generate electricity. – freep

Huge natural diamond found + Make real $15,000 diamonds in 3 days for <$100, blood free.

Miners in the southern African kingdom of Lesotho have found one of the world’s largest diamonds, a near-flawless white gem weighing nearly 500 carats, mining group Gem Diamonds said on Sunday. The diamond was discovered in the Letseng Mine on September 8, the company said in a statement. It has been analyzed by experts in Antwerp and found to weigh 478 carats, with very few inclusions and of outstanding color and clarity.”It has the potential to yield one of the largest flawless D color round polished diamonds in history,” the company said.

Letseng is one of the most productive mines in history — four of the world’s 20 largest rough diamonds have been found at the mine, including the three largest found this century. – reuters

In 2004 the mine at Letseng employed 385 “local workers.”

Blood Diamond is an Academy Award nominated 2006adventure drama film co-produced and directed by Edward Zwick and starring Leonardo DiCaprio, Jennifer Connelly and Djimon Hounsou. The title refers to blood diamonds, which are diamonds mined in African war zones and sold to finance the conflicts and profit the warlords and the diamond companies across the world. – wiki

Hopefully the workers at Letseng are adults who are treated well and compensated properly.

Diamonds were first discovered at Letseng in 1957 by explorers and was commercially mined by De Beers from 1973. – br

There is an alternative…

Lux’s Gemesis Corp. is the largest maker of lab-grown diamonds, also known in the industry as cultivated diamonds, which sell for about a third of the price of the mined gems.

Gemesis grows the stones in boxy machines in a warehouse in Sarasota, Fla., and each produces a rough 3-carat diamond in about four days – a process that takes Earth millions of years. Natural diamonds form hundreds of miles below Earth’s surface, when carbon gets trapped under great amounts of pressure, is heated and then rises to the surface.

“These are diamonds,” Lux said. “Just from a different origin: a lab.” …

Gemesis has been fine-tuning its diamond-making machines since 2000, but it’s only now that the diamonds are ready for a mass market. If local diamond retailers snap up the stones, the yellow and green products – as well as purple ones – could shimmer from local display cases this holiday season.

But first, admirers of colorless diamonds will need to be convinced that the lab-grown spoils are just as good as the gems that come from Earth’s mantle.

Rob Bates, who covers the diamond industry for the trade magazine Jewelers’ Circular Keystone, said the man-made product received a credibility boost last year when the Gemological Institute of America, the industry’s authority on valuing gems, began grading and certifying the stones just as it does mined diamonds. Jewelers at the institute found that lab-grown stones are identical to natural diamonds, which means both are the hardest material known to man. – sfgate

Read the New Diamond Age by Joshua Davis which claims Carter Clarke purchased from the Russians via Yuriy Semenov an 8,000-pound machine for $57,000 that “used hydraulics and electricity to focus increasing amounts of pressure and heat on the core of a sphere.”[Excerpt]:

The device, he was told, re-created the conditions 100 miles below Earth’s surface, where diamonds form. Put a sliver of a diamond in the core, inject some carbon, and voila, a larger diamond will grow around the sliver.

… “This is very rare stone,” he says, almost to himself, in thickly accented English. “Yellow diamonds of this color are very hard to find. It is probably worth 10, maybe 15 thousand dollars.” “I have two more exactly like it in my pocket,” I tell him. He puts the diamond down and looks at me seriously for the first time. I place the other two stones on the table. They are all the same color and size. To find three nearly identical yellow diamonds is like flipping a coin 10,000 times and never seeing tails. “These are cubic zirconium?” Weingarten says without much hope.

“No, they’re real,” I tell him. “But they were made by a machine in Florida for less than a hundred dollars.”

Weingarten shifts uncomfortably in his chair and stares at the glittering gems on his dining room table. “Unless they can be detected,” he says, “these stones will bankrupt the industry.”

… Put pure carbon under enough heat and pressure – say, 2,200 degrees Fahrenheit and 50,000 atmospheres – and it will crystallize into the hardest material known. Those were the conditions that first forged diamonds deep in Earth’s mantle 3.3 billion years ago. Replicating that environment in a lab isn’t easy, but that hasn’t kept dreamers from trying.  … Starting in the 1950s, engineers managed to produce tiny crystals for industrial purposes – to coat saws, drill bits, and grinding wheels. But this summer, the first wave of gem-quality manufactured diamonds began to hit the market. They are grown in a warehouse in Florida by a roomful of Russian-designed machines spitting out 3-carat roughs 24 hours a day, seven days a week. A second company, in Boston, has perfected a completely different process for making near-flawless diamonds and plans to begin marketing them by year’s end. This sudden arrival of mass-produced gems threatens to alter the public’s perception of diamonds – and to transform the $7 billion industry. More intriguing, it opens the door to the development of diamond-based semiconductors.

How to Make a Diamond

The Gemesis Way:
High pressure, high temperature. Crystal is created in a chamber that mimics geologic conditions.

1. Place metal solvents and graphite in ceramic growth chamber. Insert diamond seed at bottom of chamber and put chamber in center of compression sphere.
2. Force oil into top layer of sphere, creating pressure against steel anvils. Increasing pressure is transferred through anvils and onto growth chamber. Even with minimal pressure at surface, force at center reaches 58,000 atmospheres.
3. Turn on juice. Current wired to one end of ceramic chamber raises temperature to 2,300 degrees Fahrenheit. Heat and pressure cause graphite – pure carbon – to atomize. Freed carbon drawn to cooler end of chamber bonds to diamond seed, crystallizing layer by layer.
4. Wait three days.
5. Open machine. Smash growth chamber, pull out stone. Cut and polish to make sparkling diamond gem.

The Apollo Way
Chemical vapor deposition. Crystal is formed when a plasma cloud rains carbon onto diamond wafers.
1. Place diamond wafers on pedestal. Depressurize chamber to one-tenth of an atmosphere.
2. Inject hydrogen, natural gas (CH4) into chamber. Heat with microwave beam. At 1,800 degrees Fahrenheit, electrons separate from nuclei, forming plasma.
3. Let it rain. Freed carbon precipitates out of plasma cloud and is deposited on wafer seeds.
4. Let it grow. Wafer seeds gradually become diamond minibricks, building up at half a millimeter a day.
5. Open chamber and remove diamond brick. Slice into wafers for semiconductors or cut and polish to make gems.

Nearly 13,000 children in China sick due to tainted milk powder

Nearly 13,000 children in China have been hospitalised due to tainted Chinese milk powder, officials say.

China’s health ministry said 104 out of 12,892 babies showed serious symptoms. Four infants have died after drinking the milk of the Sanlu Group containing the industrial chemical melamine, which could cause urinary problems. Meanwhile, in Hong Kong, a toddler has been diagnosed with a kidney stone after drinking the powder – the first such case outside mainland China.  A number of Asian and African countries have now banned Chinese dairy imports following the scandal. Chinese police have arrested 18 people in connection with the scandal….

They said that 1,579 babies had been treated and discharged, adding that hospitals had checked nearly 40,000 baby patients. Meanwhile, Chinese Prime Minister Wen Jiabao said that the authorities were doing everything possible to “prevent this happening again, not just with milk products, but with all foods”.- bbc

The look on that little guy’s face says it all. “What the heck is wrong with you adults? You are supposed to keep us safe, not make us sick.”

Blog: Enabling Gears and Https

WordPress.com is always making improvements and I enjoy trying them out. This blog is now more secure with https: encrypting my log in and I’ve enabled the “Trubo” option which uses Gears for firefox, so I should be able to add content faster. We shall see. I’ve been experimenting with a blogging add on called “Deepest Sender”. Will that still work with https?
