Zap of Electricity Creates Fluid Situation for Liquid – New Substance Shifts to Solid and Back With Flip of Switch

With frost warnings popping up across the country, Americans are getting their seasonal reminder that when temperatures get low enough, liquids become solid.

Mobile phones can trigger eye damage, fear scientists

Saturday, August 6th, 2005

I feel somewhat vindicated for using an earphone with my cell phone for the past 5 years. I had heard of research that there was a relationship between cell phone use and eye cancer. It seemed that all of the MSM media was focused on cell phones causing brain tumors. The eye cancer is the one that caught my attention. At any rate use an earphone if you use cell phones…

Prolonged use of mobile phones can lead to permanent eye damage including cataracts, scientists believe.

Medical researchers have found that microwave radiation of the type emitted by mobile phones causes eye tissue to “bubble” – a precursor to the formation of cataracts – and can also interfere with the ability to focus.

Science@NASA J-Track 3D

Thursday, July 28th, 2005

We hope you enjoy J-Track 3-D. It should appear in its own window and begin loading a database of over 500 satellites.

What you will see (assuming your system supports this JAVA applet) is a plot in 3-dimensions showing the position of these satellites. Be sure to try the “Satellite” pull-down menu to choose which satellite you wish to view.

Smoking Marijuana Does Not Cause Lung Cancer

Friday, July 8th, 2005

Marijuana smoking -”even heavy longterm use”- does not cause cancer of the lung, upper airwaves, or esophagus, Donald Tashkin reported at this year’s meeting of the International Cannabinoid Research Society. Coming from Tashkin, this conclusion had extra significance for the assembled drug-company and university-based scientists ( most of whom get funding from the U.S. National Institute on Drug Abuse ). Over the years, Tashkin’s lab at UCLA has produced irrefutable evidence of the damage that marijuana smoke wreaks on bronchial tissue. With NIDA’s support, Tashkin and colleagues have identified the potent carcinogens in marijuana smoke, biopsied and made photomicrographs of pre-malignant cells, and studied the molecular changes occurring within them. It is Tashkin’s research that the Drug Czar’s office cites in ads linking marijuana to lung cancer.

There was time for only one question, said the moderator, and San Francisco oncologist Donald Abrams, M.D., was already at the microphone: “You don’t see any positive correlation, but in at least one category [marijuana-only smokers and lung cancer], it almost looked like there was a negative correlation, i.e., a protective effect. Could you comment on that?”

“Yes,” said Tashkin. “The odds ratios are less than one almost consistently, and in one category that relationship was significant, but I think that it would be difficult to extract from these data the conclusion that marijuana is protective against lung cancer. But that is not an unreasonable hypothesis.”

Mad Cow From Texas

Friday, June 24th, 2005

Second US case of Mad Cow confirmed.
The initial rapid screening test in November was positive, but a more
stringent test was negative, and the USDA told America that the cow was
BSE-free. The agency did not mention that it had skipped the Western Blot test, used in 2003 to confirm the first U.S. mad cow.

No Wings? No Chutes? No Problem

Space agencies around the world, take note: The burgeoning private space industry isn’t content to follow your lead.

Homebrew Air Conditioning

Wednesday, June 15th, 2005

I’m a student, with limited funds and a cheap house without air conditioning. To avoid dying this summer, I’ve built a primitive air conditioner. It’s a basic heat pump, using water as the medium. You’ll probably need to fiddle a bit with the dimensions of the supplies based on your resources and preferences.

Thrillionaires: The New Space Capitalists

Monday, June 13th, 2005

Paul G. Allen’s first foray into rocketry, as he recalls it, was inauspicious.

“My cousin and I tried to build a rocket out of an aluminum armchair leg,” he said. At just 12 years old, the future billionaire raided his chemistry set for zinc and sulfur, and packed the fuel mixture into the tube. He got the formula right, but had not looked up the melting point of aluminum.

“It made a great noise,” he said, “and then melted into place.”

His rockets have gotten better since then, and a lot bigger, too. Mr. Allen, who became a co-founder of Microsoft, is responsible for SpaceShipOne, the pint-size manned rocket that won the $10 million Ansari X Prize competition last year as the first privately financed craft to fly to the cusp of space – nearly 70 miles up.

‘Mutant’ children are best

Thursday, May 26th, 2005

It would appear that Marvel comics was way ahead of it’s time with X-Men.

THE Chernobyl nuclear disaster has spawned a generation of ‘mutant’ super-brainy children.
