How Long Can a Nuclear Reactor Last?

OLDIE BUT GOODIE: Extending the life span of aging nuclear power plants could be essential to meet the nation's energy needs. WIKIMEDIA COMMONS/GREUDIN

From Scientific American:

Industry experts argue old reactors could last another 50 years, or more.

Could nuclear power plants last as long as the Hoover Dam?

Increasingly dependable and emitting few greenhouse gases, the U.S. fleet of nuclear power plants will likely run for another 50 or even 70 years before it is retired -- long past the 40-year life span planned decades ago -- according to industry executives, regulators and scientists.

High-Fliers Swear A 5am Start Is The Key To Success

Photo: Yawn chorus: Is 5am a productive time to begin the day?

From The Daily Mail:

But how do you do it all, I asked my high-powered friend Fiona, who had just reeled off her latest long list of projects. 'Oh, I get up at 5am,' she said. 'So by breakfast time, I've cleared emails, been through the diary and can hit the ground running.'

That did it. For years, I've heard people proclaim the advantages of early rising. Yoga teachers, life coaches and exercise gurus swear by its benefits for the body.

Over-achievers find it's the best time to get things done because their brains are fresh and ready for action.

Anna Wintour, the editor of American Vogue, famously rises at 5am to fit in an hour's tennis before her 6am blow-dry each day.

From The Guardian:

Woolly mammoths and other giant ice-age mammals faced extinction 2,000 years before deadly speartips were invented.

Woolly mammoths and other large, lumbering beasts faced extinction long before early humans perfected their skills as spearmakers, scientists say.

The prehistoric giants began their precipitous decline nearly 2,000 years before our ancestors turned stone fragments into sophisticated spearpoints at the end of the last ice age.

U.S. Exhausted Oil And Gas Supplies — Repeatedly -- A Commentary

From The Houston Chronicle:

What city contributed most to the making of the modern world? The Paris of the Enlightenment and then of Napoleon, pioneer of mass armies and nationalist statism? London, seat of parliamentary democracy and center of finance? Or perhaps Titusville, Pa.

Oil seeping from the ground there was collected for medicinal purposes — until Edwin Drake drilled and 150 years ago — Aug. 27, 1859 — found the basis of our world, 69 feet below the surface of Pennsylvania, which oil historian Daniel Yergin calls “the Saudi Arabia of 19th-century oil.”

For many years, most oil was used for lighting and lubrication, and the amounts extracted were modest. Then in 1901, a new well named for an East Texas hillock, Spindletop, began gushing more per day than all other U.S. wells combined.

Since then, America has exhausted its hydrocarbon supplies.

From Science Daily:

Science Daily (Nov. 22, 2009) — Solar wind generated by the sun is probably driven by a process involving powerful magnetic fields, according to a new study led by UCL (University College London) researchers based on the latest observations from the Hinode satellite.

Scientists have long speculated on the source of solar winds. The Extreme Ultraviolet Imaging Spectrometer (EIS), on board the Japanese-UK-US Hinode satellite, is now generating unprecedented observations enabling scientists to provide a new perspective on the 50-year old question of how solar wind is driven. The collaborative study, published in this month's issue of Astrophysical Journal, suggests that a process called slipping reconnection may drive these winds.

(Mercer Photography / University of Massachusetts Medical School)

Dr. Paul Zamecnik Dies At 96; Scientist Made Two Major Discoveries -- L.A. Times

He discovered transfer RNA, a crucial molecule in the synthesis of proteins in the cell, and antisense therapy, in which strands of DNA or RNA are used to block the activity of genes.

Most scientists are fortunate if they can make one major discovery in their lifetime. Dr. Paul Zamecnik made two, each of which should have won him a Nobel Prize.

Working with Dr. Mahlon Hoagland, he discovered transfer RNA, a crucial molecule in the synthesis of proteins in the cell. Later, he invented the idea of antisense therapy, in which strands of DNA or RNA are used to block the activity of genes -- a concept that is now being turned into a new class of drugs for cancer, HIV and a host of other diseases.

Why do we yawn? Dogs do it, lions do it, even babies in the womb do it - but nobody really knows why. Theories abound. We open wide when we are tired, bored, or hungry. Some have suggested that a sudden drop in blood oxygen, or a surge of carbon dioxide pumped out by a tired body, sparks it off – but no, breathing air rich in that gas, or with extra oxygen, makes no difference.
