The quest for a theory linking all matter and all forces led physicists deep into hyperspace, where they got horribly lost. But suddenly the way ahead has become clear, says superstring theorist. Michio Kaku

Worrisome “quiet” in genes may predict lung cancer
Worrisome “quiet” in genes may predict lung cancer

The same may be true of genes that guard against lung cancer, researchers have found. They identified 15 such genes, adding that these could help predict cancer: if their collective activity becomes too quiet, it suggests other factors in the cell are suppressing them, a possible step toward cancer.
A test for these genes in normal cells sampled via bronchoscopy could identify people at risk for lung cancer, said James C. Willey of the University of Toledo, Ohio, the lead researcher.
In a study of 49 people, about half of whom had lung cancer, Willey and his colleagues said they identified those patients correctly 96 percent of the time. Willey cautioned that more, larger studies will need to be done to see if such a test can identify future cancer sufferers before they become sick.
“Smoking causes about 90 percent of all lung cancer cases, yet only about 10 to 15 percent of heavy smokers will develop lung cancer,” said Willey. “We are looking for new techniques that will allow us to pick out the 10 to 15 percent of individuals at highest risk for lung cancer from the enormous pool of current and former smokers.”
The United States alone has more than 40 million current or former heavy smokers, he added. And although increasingly powerful screening tools are available to detect lung cancer early, it’s very costly to screen all these people. The new test could lead to better targeted screening, Willey said.
To find which genes are active in lung cancer, Willey and his colleagues look for levels of messenger RNA transcripts—instructions copied from DNA that direct cells to create specific protein molecules.
Previously, the researchers had found that genes that protect lung cells from damage caused by smoke or toxins are poorly regulated in lung cancer patients. In the new work, the team tested their theories by measuring “transcript abundance” of 15 genes that encode protective antioxidant and DNA repair proteins in lung airway cells. Transcript abundance is an indicator of gene activity.
The findings were presented Sept. 18 at the American Association for Cancer Research’s International Conference on Molecular Diagnostics in Cancer Therapeutic Development, in Atlanta, Ga.

Cellphone chat may cause cancer
Cellphone chat may cause cancer
http://www.dawn.com/2007/08/31/int11.htm
LONDON: Just 10 minutes of chatting on cellular phones is enough to trigger such chemical changes in the brain that can increase the risk of cancer, warn scientists.
A study by the Weizmann Institute of Science in Israel has shown that even low levels of radiation from handsets interfere with the process of cell division, which encourages the growth of tumours.
Although the researchers have yet not found any evidence that signals from cellphones are harmful, their findings suggest they may be.
Several studies have been conducted to find an association between mobile use and brain tumours, but they neither found any such link nor any dramatic rise in cancer rates.
Ever since the inception of mobile phones, the official advice has been that the device are safe. The guidance is based on the assumption that the phones emit too little radiation to heat the brain dangerously.
The new study, however, suggests that �non-thermal� radiation can pose a risk.
In lab tests, the researchers exposed human and rat cells to low-level radiation at 875 megahertz, a similar frequency to the one used in many mobile phones.
Despite being weaker than emissions from a typical handset, the radiation began to switch on a chemical signal inside the cells within 10 minutes, say the researchers. The chemical signals detected were involved in the division of cells, they add.
The researchers also claimed to have found a separate way in which mobile phones can damage health.
�The significance lies in showing cells do react to cellphone radiation in a non-thermal way,� the Daily Mail quoted Dr Rony Seger, a co-author of the study published in the Biochemical Journal , as telling New Scientist magazine.�Dawn/The Times of India News Service

Probiotics for cancer prevention?
Probiotics for cancer prevention?
Probiotics may offer other health benefits, but one receiving more support recently is the possibility of helping to prevent colon cancer. If results of a small but well-controlled study in Ireland are repeated, probiotics - live bacteria that can benefit health - might have a place alongside vegetables, legumes, whole grains and regular exercise in our strategies to lower risk of cancer. Studies suggest that probiotics restore a healthy bacteria population in the gut and prevent diarrhea. Because colon cancer takes years to develop, the scientists looked at various signs of its early development. This study included 80 people who either had colon cancer tumours or non-cancerous colon polyps (precursors to cancerous tumors) recently removed. After 12 weeks, researchers found that the balance of colon bacteria had changed in those receiving the synbiotic, with more Lactobacillus and Bifidobacterium and less of the bacteria (Clostridium) that is linked with increasing cancer risk. Compared to patients who received placebos after polyp removal, those who received synbiotics showed decreased DNA damage in the lining of the colon and decreased growth and reproduction of colon cells (which increase in colon cancer). Neither of the groups reported adverse effects of synbiotics.

eBook: Full Bodybuilding Course
I would like you to practice Lesson One throughout your entire Course. Likewise follow the valuable food information in Lesson Two all through the Course. Every two weeks I would like you to add two new lessons to Lesson One. Then drop those two Lessons and take the next two new ones. For example; Practice Lesson One for two weeks then add Lesson 2 and 3. Practice these for two weeks then drop Lesson 3 and add Lessons 4 and 5.
After two weeks drop 4 and 5, and add 6 and 7. Continue this until you finish all the Lessons. But
remember to continue the exercises in Lesson 1 and the food information in Lesson 2 all through
the Course. Also, remember as a rule, do all exercises 10 - 12 times (reps) or until you become tired, unless otherwise specified. Study the written instructions as much as the photos illustrating the exercises so that you are sure to be doing them correctly.

A nuclear revival is welcome so long as the industry does not repeat its old mistakes
[The Economist September 08, 2007]
IN MARCH 1986 this newspaper celebrated “The Charm of Nuclear Power” on its cover. The timing wasn't great. The following month, an accident at a reactor at Chernobyl in Ukraine spread radioactivity over Europe and despair in the Western world's nuclear industry.
Some countries never lost their enthusiasm for nuclear power. It provides three-quarters of French electricity. Developing countries have continued to build nuclear plants apace. But elsewhere in the West, Chernobyl, along with the accident at Three Mile Island in Pennsylvania in 1979, sent the industry into a decline. The public got scared. The regulatory environment tightened, raising costs. Billions were spent bailing out lossmaking nuclear-power companies. The industry became a byword for mendacity, secrecy and profligacy with taxpayers' money. For two decades neither governments nor bankers wanted to touch it.
Now nuclear power has a second chance. Its revival is most visible in America (see article), where power companies are preparing to flood the Nuclear Regulatory Commission with applications to build new plants. But the tide seems to be turning in other countries, too. Finland is building a reactor. The British government is preparing the way for new planning regulations. In Australia, which has plenty of uranium but no reactors, the prime minister, John Howard, says nuclear power is “inevitable”.
Managed properly, a nuclear revival could be a good thing. But the industry and the governments keen to promote it look like repeating some of the mistakes that gave it a bad name in the first place.

Nawaz Sharif: Again in Saudi Arabia
Ah! Nawaz Sharif came back after a decision from supreme court. But military government kicked him back to Saudi Arabia for another unknown time. How a beautiful joke? Pakistan's juditiary (ADLIYA) allow him to come back on legeal grounds and the dictator of the countary forcely kicked him away from the countary. Is there no law exist in Pakistan? I think yes, no law exist in Pakistan, everywhere. The single rule served here in Pakistan is : "Might is right"
