MOSCOW - Russia and Iran signed Tuesday a supplementary agreement on the delivery of 80 metric tons of nuclear fuel to a nuclear power plant in southern Iran in March 2007, the head of Russia's nuclear exporter said.
Russia is helping Iran build the plant at Bushehr, 400 kilometers (250 miles) southwest of the capital, Tehran. The NPP is being constructed under the supervision of the International Atomic Energy Agency, the UN's nuclear watchdog.

IF YOU are trying to commit something to memory, take a nap. Even a short daytime snooze could help you learn.
In science we aim for a picture of nature as it really is, unencumbered by any philosophical or theological prejudice. Some see the search for scientific truth as a search for an unchanging reality behind the ever-changing spectacle we observe with our senses. The ultimate prize in that search would be to grasp a law of nature - a part of a transcendent reality that governs all change, but itself never changes.
The idea of eternally true laws of nature is a beautiful vision, but is it really an escape from philosophy and theology? For, as philosophers have argued, we can test the predictions of a law of nature and see if they are verified or contradicted, but we can never prove a law must always be true. So if we believe a law of nature is eternally true, we are believing in something that logic and evidence cannot establish.

We live in a time when interest in science is at its highest, but trust in science is at its lowest. Polls and other investigations show that the public is aware of the important role that science has taken upon itself, but that they are concerned about its increasing commercialisation, the way it is presented in the media, and they would also like to have more influence on what the scientific endeavour chooses to research. The question arises: to what extent should we place our trust in science?
Science magazine this week details the discovery of a stone block in Veracruz, Mexico, that contains a previously unknown system of writing; believed by archeologists to be the earliest in the Americas.
The slab - named the Cascajal block - dates to the early first millennium BCE and has features that indicate it comes from the Olmec civilization of Mesoamerica. One of the archaeologists behind the discovery, Brown University's Stephen D. Houston, said that the block and its ancient script "link the Olmec civilization to literacy, document an unsuspected writing system, and reveal a new complexity to this civilization."

In 1989, I published the first in a series of books about the Second World War and its aftermath. The first, Other Losses, showed the tremendous atrocities committed against enemy prisoners in the prison camps of the US and France after 1945. The next, Just Raoul, was a biography of a hero of the French Resistance who saved many refugees from Nazi death camps. The next, Crimes and Mercies, described the full extent of all allied crimes against Germans, plus the wonderful charity work of Canada and the USA in saving 800 million people, including Germans, Japanese and Italians, from starving to death in the hungry years after 1945. The next, Dear Enemy, illuminated the attitudes of the western allies to Germany from 1945 to now.
Wikipedia reviews and criticizes only Other Losses, and in such a biassed way, that I finally tried to correct their many errors. Starting in March, 2006, I tried repeatedly over many weeks to correct the errors, but found that within a day at first, then within hours, and finally within minutes, some Wikipedian editor had expunged my corrections, replacing them with ever more hostile and denigrating allegations. Friends of mine tried also to correct the flawed Wikipedia article, but found the same situation. Finally we decided that Wikipedia was deliberately censoring my contributions, and that it was pointless to continue trying to present the facts on Wikipedia. After Serendipity (already acquainted with censorship at Wikipedia) heard of this situation I was offered the chance to publish the real story, which appears below.

Astronomers meeting in the Czech capital have voted to strip Pluto of its status as a planet.
About 2,500 experts were in Prague for the International Astronomical Union's (IAU) general assembly.
The scientists rejected a proposal that would have retained Pluto as a planet and brought three other objects into the cosmic club.

It looks like a heap of rubbish, feels like flaky pastry and has been linked to aliens. For decades, scientists have puzzled over the complex collection of cogs, wheels and dials seen as the most sophisticated object from antiquity, writes Helena Smith. But 102 years after the discovery of the calcium-encrusted bronze mechanism on the ocean floor, hidden inscriptions show that it is the world's oldest computer, used to map the motions of the sun, moon and planets.
'We're very close to unlocking the secrets,' says Xenophon Moussas,an astrophysicist with a Anglo-Greek team researching the device. 'It's like a puzzle concerning astronomical and mathematical knowledge.'

ANKARA, Aug. 20 (Xinhua) -- A joint team of Turkish and U.S. archeologists will start excavating an ancient Hittite city in southeastern Turkey next month, the semi-official Anatolia news agency reported on Sunday.
The excavation of Zincirli Tumulus city, which is located in Islahiye town of Gaziantep province, will begin on Sept. 1 and David Schloen, Associate Professor of Chicago University, will head the team, said the report.

TOKYO - Dell Inc.'s recall of 4.1 million notebook computer batteries could cost Sony Corp. anywhere from 10 billion yen to 50 billion yen ($85-$430 million), hurting the Japanese electronics maker's short-term earnings and its brand image, analysts said.
"As the batteries were made by Sony, the possible impact of the news on Sony's earnings is a concern," said Eiichi Katayama, an analyst at Nomura Securities Co. Ltd. "Until management discloses details of the cause, the risk of a larger impact remains."
