Vitamin C produces gene-damaging compounds, test-tube study in Science reports
... much damage as it's preventing, but that's really speculation at this point. What we can say is that vitamin C clearly doesn't work when you expect it to, and now we're in a position to see if that's what's happening in vivo , [or, in living cells]" Blair said. Some scientists have long recommended dietary......quencing director Paul Predki. "There had been speculation that aligning the human and mouse DNA sequence might reveal many more genes," Stubbs said. "However, if chromosome 19 is indicative of other chromosomes, the estimate of 30,000 genes is fairly accurate." Before the comparison of human and mous...Knockout of cav-1 protein causes loss of a cellular organelle
...ery of caveolae their function remains a matter of speculation and controversy. The study provides clues as to the function of these organelles and also provides the first example of the effect of removing a cellular organelle. Caveolae have been associated with various cellular processes such as transcytosis of...Ecstasy component may help researchers measure brain damage from the drug

The findings may corroborate speculation that HHMA (3,4 dihydroxymethamphetamine), is at least partially responsible for Ecstasys harm to the human brain, according to lead researcher Rafael de la Torre, D.Pharm., of the Municipal Institute of Medical Research in Barcelona.

In the September 20, 2001 edition of Science Express, the researchers report that manipulating one of these signaling proteins in the developing mouse brain causes radical changes ...Betting on climate change: Alaskan gambling contest yields treasure trove of scientific data
...op work. According to Ice Classic historians, idle speculation about when the ice would break up is what led to the wagering. To determine the contest winner, the engineers came up with an ingenious contraption still in use today. It consists of a tall tripod made of wooden logs painted with black-and-white stri...Science Report: Super-crocodile crawls out of the African Cretaceous
...ok at hyper giant crocodiles--there's been rampant speculation about what they looked like and where they fit in the croc family tree, but no one had enough of the skull and skeleton to really nail any the of true croc giants down until now," says Sereno. The Science researchers confirmed that "massive" is one...Deep-ocean research program office established at Penn State

...he authors emphasize that this interpretation is a speculation awaiting further experimental proof. The authors also note that they found that an increased resistance predicted a lower likelihood of the presence of flow-limited breaths. This finding would indicate that a more narrow airway would be less prone t...Study examines data withholding in academic genetics
... of data withholding by their peers. Despite some speculation in earlier reports that data withholding was more common in genetics, the geneticists were no more likely to report denial of their requests than were the non-geneticists. Among the geneticists responding to the survey, 12 percent said they had deni...The new biology of rocks: 'Are there medical implications of geomicrobiology?'

Interestingly, while the early Viking and Mariner space probes were gathering data from Mars in the 197...USF presents new research on hyperlipidemic children

But Thompson says it may be the Terminator label itself that caught the public eye. The Terminator name was given to the technology by anti-biotechnology interest groups. ...First live studies of important cell structures may shed light on Alzheimer's, other diseases
