U.S. threatens to abandon Saudis and their oil // via drudgereport.com

	'U.S. officials said the Bush administration has warned that Americans  
would not stay in Saudi Arabia unless the kingdom takes significant  
steps to protect them. The officials said the warning came in wake of  
the Al Qaida execution of Lockheed Martin engineer Paul Johnson on June  
18.' .... 'On June 20, Senate Foreign Relations Committee chairman Sen.  
Richard Lugar issued the most specific warning to Riyad. Lugar, a  
Republican close to Secretary of State Colin Powell, said that unless  
Saudi Arabia provides better protection to Americans "they're in deep  
trouble with regard to the oil business."'

World Of Worry Over Nukes // nuclear diplomacy, politics, terrorism.

	'The Bush administration is pressing for more cooperation from  
suspected nuclear weapons developers Iran and North Korea, but coming  
under criticism for neglecting the danger of nuclear proliferation.'  
.... 'In remarks to the Carnegie Endowment on Monday, International  
Atomic Energy Agency chief Mohammed ElBaradei said that "all evidence  
to date indicates that Iraq's nuclear weapons program had been  
effectively dismantled in the 1990s through IAEA inspection — as we  
were nearly ready to conclude before the war."' .. 'He claimed that  
"the Iraq experience demonstrated that inspections — while requiring  
time and patience — can be effective even when the country under  
inspection was providing less than active cooperation."' .. 'The  
Massachusetts Democrat [Sen. Kennedy] said the administration's efforts  
to rid Iraq of a nuclear program it didn't have not only has destroyed  
U.S. credibility around the world, but has made al Qaeda terrorists  
more determined to launch a nuclear attack on America.' .. 'Kennedy  
said the administration's unilateralism has caused a serious setback in  
nonproliferation policies. And he said Bush has compounded that neglect  
by pursuing research into a new type of nuclear weapon, called "bunker  
busters." The Senate last week rejected an effort to strip funding for  
the administration's research into mini-nukes.'

	'The capacitors, C, are charged up in parallel via the 1M (one megohm)  
resistors, so they each become charged to the input voltage. When first  
(leftmost) spark gaps breaks down (sparks), the voltage across the next  
increases, causing it to break down, and so on for all the other gaps.  
When all gaps have broken down, the low impedance of the ionised air in  
the sparks effectively connects all the charged capacitors in series,  
multiplying the input voltage by the number of capacitors. The ionised  
air path has sufficiently low resistance that the charge resistors  
don't have any significant effect.'

Toxic Pollution Rose 5 Percent in 2002 // .US, Environmental Protection  

	'The annual inventory is considered by EPA officials as one of the  
most important things the agency does, and is routinely criticized by  
some companies as too demanding and by some health and environmental  
groups as too lax.' .... 'Sen. Jim Jeffords, I-Vt., a senior member of  
the Senate Environment and Public Works Committee, said the pollution  
count shows the Bush administration is largely ignoring environmental  
protection.' .... 'The biggest polluters in recent years have been  
hard-rock mining companies and coal-burning power plants, according to

Rapid Urbanization In China Warming Regional Climate
Faster Than Other Urban Areas

	'Most scientists agree that land use changes from urbanization create  
an urban heat island (UHI) that is partially responsible for the  
observed warming over land during the past few decades. The cities'  
predominance of buildings, roads and paved surfaces with little  
vegetation largely explains the UHI effect.'

Yucca Nuclear Dump Funding Plan Draws Industry Ire

	'A plan by Republican Sen. Pete Domenici to tack a $446 million  
surcharge on utility customers to pay for a Nevada nuclear waste site  
drew the ire of nuclear power plant owners on Monday.' .. 'New Mexico  
Republican Domenici, a long-time nuclear industry ally, has drawn rare  
industry criticism for his plan to raise fees paid by utility customers  
by 60 percent in fiscal 2005, which starts Oct. 1.' .... 'Since 1983,  
utility customers have paid a fee of 1/10 of a cent per kilowatt-hour  
to a fund that holds about $15 billion earmarked to develop and build  
the Yucca facility, which would be the first permanent U.S. nuclear  
waste repository.' .... 'Spent fuel from the nation's nuclear plants  
has been piling up for years. An estimated 50,000 tons (45,500 metric  
tons) of it is stored at 72 sites in 33 states, mostly near urban areas  
in the East and Midwest.'

Cheney a chance to advance the White House agenda. But it's what the he  
didn't talk about that is getting a lot of attention here Thursday  
evening.' .... '"We know we have a difference of opinion with this  
administration on that issue." Nevada Senator John Ensign says when it  
comes to Yucca Mountain state lawmakers have ~agreed to disagree~ with  
the Bush Administration. John Morgan paid $250 to hear the speech. He  
sees the financial benefits of Yucca Mountain, but was looking to the  
Vice President for guidance on the issue.   "Yeah, I'm interested to  
see what's going to happen. I think we could use the money out of Yucca  
Mountain. That's a deep hole they can put a lot of stuff down there."'

	'Historically, DOE has striven to keep its most critical assets at a  
low risk level and may insist on immediate compensatory measures should  
a significant vulnerability develop that increases risk above the low  
risk level. Compensatory measures could include deploying additional  
protective forces or curtailing operations until the asset can be  
better protected.'

Investigators Suspect Inside Help in Iraqi Pipeline Blasts // press  

	'The two southern explosions — in which the bombs  were placed with   
precision amid the welter of buried gas, water, oil and petrochemical  
pipelines crisscrossing the open desert — had immediately raised  
suspicions that someone inside the company may have been involved.'

world, according to the latest Capgemini Global Utilities Survey,  
released this week.' .. 'The survey is based on interviews with senior  
utilities executives worldwide, including representatives of all of New  
Zealand’s major gas and electricity companies.' .... '“The electricity  
blackouts experienced in London, Italy and New York in the last  
northern summer were reflected in the survey respondents’ uncertainty,  
particularly in terms of how electricity markets will work to ensure  
sufficient supply and reliable delivery of electricity,” Mr Hancock  
said.' .. 'He said the survey highlighted a lack of clarity  
internationally on who is responsible for securing electricity supply.'  
.. '“The events of 2003 reawakened concerns about deregulation and its  
challenges and benefits.  This year’s survey shows that there are some  
important questions to consider around regulatory uncertainty,  
political intervention and a lack of long term price signals to support  
investment,” he said.' .... 'Mr Hancock said the survey pointed to the  
need to continually review and renew electricity market design, to  
ensure markets continue to deliver reliable electricity at appropriate  
prices over the long term.'

satellites could be repositioned to deliver energy to receiving  
stations in multiple locations.' .... 'Bush has repeatedly said that  
the United States must become less reliant on foreign sources of energy  
as a matter of national security, but his administration has given  
solar power from space the cold shoulder. While his administration has  
allocated millions of dollars for research into alternative fuel  
sources such as nuclear fusion and hydrogen , according to John  
Mankins, assistant associate administrator of advanced systems at NASA,  
there has been no funding for space solar power since 2001.'

'Wireless pebbles' track glaciers // ingenuity...

	'The low-powered pebble probes are placed near the bottom of the

and the makeup of the glacier's sediment.' .. 'They are positioned at  
the base at a depth of about 60-90m after a hot water drill, like a  
powerful carwash, has drilled a hole deep enough.' .. '"They send back  
their signals to the surface by radio, and these are picked up on a  
surface base station, which also records temperature and velocity.' ..  
'"It has a webcam and snow meter, and it is able to track the position  
of these probes we have put in," said Dr Hart.' .. 'The base station  
then sends the information by radio to the monitoring team's campsite.  
That data is then fed into a computer and put online to make it  
available instantly to glaciologists around the world.' .. 'At 14cm  
long, the tough polyester shells housing the probes are designed to be  
as much like a pebble as possible.' .. 'That way, they match the way  
sediment that gets caught up at the bottom of glaciers flows with the  
ice and meltwater.'

painting by introducing random visual noise - the equivalent of the  
snow seen on a badly tuned TV set - and asked 12 observers how they  
rated the resulting expression on a four-point scale from sad to  
happy.' .. 'As would be expected, noise that lifted the edges of her  
mouth made Mona Lisa seem happier, and those that flattened her lips  
made her seem sadder. More surprising though, was how readily the  
visual noise changed people's perception of the Mona Lisa's expression.'

Mini Transistors May Give Microprocessors a Maxi Boost // **  
"This is the first demonstration of a nanotube operating in the  
frequency range
of microwaves -- electromagnetic waves with faster frequencies than  
waves," says American Chemical Society spokesperson Jason Gorss. For  
and computer users, the discovery could mean speeds up to "1,000 times"  

	'Burke and his colleagues varied the voltage on an electrical circuit  
made from a carbon nanotube sandwiched between two gold electrodes.  
They discovered that the circuit operated at a frequency of 2.6  
gigahertz (GHz), which means electrical current could be switched on  
and off in about one billionth of a second.' .... '"I estimate that the  
theoretical speed limit for these nanotube transistors should be  
terahertz (1,000 GHz), which is about 1,000 times faster than modern  
computer speeds," Burke said.' .... 'High-speed nanotube transistors  
could be useful in a number of applications, such as "very low noise  
microwave amplifiers that could increase the range in which cell phones  
operate," Burke explained.' .. 'Nanotubes might also form "integrated  
nanosystems," doing the work of two components in one chip -- noise  
filtering and amplification, for instance.' .. '"Ultimately, we would  
like more sophisticated circuits on a single chip," Burke told
