Malibu dentist aims to ban mercury amalgam fillings (3) Oct 25, 2009
I was also told by the toxicologist that it has a long half life, so that the mercury that I played with as a child could still be doing damage to my body today. I had all the mercury fillings in my mouth replaced - but as a dentist, I was still removing old fillings and inhaling the unsuspecting colorless, odorless toxic gas that was being created by the drill.

Scientists Try to Debunk Shroud of Turin Oct 7, 2009
Group Funded by Italian Atheists, Agnostics Claims Experiment "Clearly Indicates" Shroud Was Man Made. In this Aug. 12, 2000 file photo, The Holy Shroud, a 14 foot-long linen revered by some as the burial cloth of Jesus, is shown at the Cathedral of Turin, Italy. (CBS News -- Sci/Tech)
Survival trumps aesthetics Aug 30, 2009
Nuclear power: The waste is the most toxic stuff in the cosmos and has a half life of 28,000 years. The fuel can be diverted toward civilization-busting bomb production. (Logan Herald Journal, UT)
Remote-control closed system invented for inserting radio-active atoms inside fullerenes Jul 8, 2009
It all takes less than a day, which is important because 177Lu has a half life of six and one-half days. "So we can't take 30 days to make the product," said Duchamp. (EurekAlert!)
Ongoing worldwide shortage of medical isotopes could threaten patient care, says expert Mar 19, 2009
Around 80 per cent of clinical nuclear medicine work is dependent on the routine availability of the radioisotope molybdenum-99 (Mo-99), from which Tc-99m is derived, which has a half-life of three days and cannot therefore be stockpiled. Ninety-five per cent of the world's Mo-99 is produced by five commercial nuclear reactors NRU at Chalk River in Canada, HFR at Petten in The Netherland, BR-2 at Fleurus in Belgium, OSIRIS at Saclay in France and SAFARI-1 at Pelindaba in South Africa.

The Plain Truth About Glorious Carbon Dioxide Feb 28, 2009
" -- Suggest you follow the excellent advice of Roger Arnold above. And one of the very best days I've had in many years was the day several years ago when I first encountered (on PhysOrg.com newssite) the theory that cosmic rays could be a (to then ignored) significant balancing factor in earth's climate. The theoretical arguments were very carefully presented, very solid science and it looked to me like this single item might have the potential to allow me to significantly re-formulate my...

New models question old assumptions about how many molecules it takes to control cell division Feb 25, 2009
To achieve this level of control, the Virginia Tech researchers conclude, in their PNAS paper, that 1) the average number of specific mRNA molecules must be 5 to 10 times larger than the generally accepted value, or 2) the half-life of mRNA molecules must be 10 to 20 times shorter than the reported value, or 3) the cell must have specific mechanisms for noise reduction in its mRNA populations. Or some combination of these strategies. (EurekAlert!)
