It's an assumption Tower began to seriously question about a year and a half ago, eventually deciding to include both male and female flies in all...Newly discovered West Coast arrhythmias cause
...upwelling," says Peterson. "What's catching us by surprise is the rate at which warming is hitting us. And, of course, how fast the ocean has changed -- that is what amazes me." The scientists hope that by better understanding the interplay of warming, winds, and storms with ocean currents and biological ...Penn researchers replace organ in adult mice using 'single-parent' stem cells
... could actually repopulate an adult organ. To our surprise we also found that by using male-only derived embryonic stem cells, we could do the same," McLaughlin said. "In humans, this could provide a therapeutic route for both genders; members of either sex can use this technique to produce compatible stem ...New bird, bat species revealed by extensive DNA barcode studies
...the vegetables in your soup. Perhaps the biggest surprise is that DNA barcoding works as well as it does, that a relatively short code of genes distinguishes species so clearly and there isn't more blurring between species, says Dr. Stoeckle. Barcoding has prompted speculation and theories about mechanism...Scientists identify specific enzymes that make meningitis hard to fight
... are known to cut theDNA during its repair. To our surprise we discovered that in themeningitis bacteria, one of the enzymes does not cut the DNA. Instead,it removes damaged DNA ends that prevent the DNA from being remadeduring the repair process.
